For example, the control device controls the cleaning device to perform cleaning operations, and the control device controls the charging device to charge the cleaning device. In this way, the operation of the cleaning device and/or the charging device is controlled based on the operating information of the cleaning device or the charging device, ensuring the reliability of the operation of the cleaning device and/or the charging device, thereby ensuring the accuracy of the reliability of the operation of the cleaning device.

The cleaning device according to the present application may also have the following additional technical features:

In some technical solutions, optionally, the detection device includes: a first coil, which is arranged in the cleaning device; a second coil, which is arranged in the charging device; the control device includes: a receiving control circuit, which is arranged in the cleaning device; and a transmitting control circuit, which is arranged in the charging device; after the first coil and the second coil signals are connected, the receiving control circuit is used to adjust the coil impedance of the first coil according to the working information of the cleaning device; the second coil is used to sense the coil impedance of the first coil and generate an induced current signal, and the transmitting control circuit is used to demodulate the induced current signal to obtain working information, and control the charging device to perform working tasks on the cleaning device according to the working information, and/or control the second coil to send a power transmission signal to the cleaning device according to the working information, so as to provide charging power to the cleaning device through the power transmission signal for charging.

In this technical solution, the detection device may specifically include a first coil and a second coil, and the control device may specifically include a receiving control circuit and a transmitting control circuit.

The receiving control circuit and the first coil are both arranged in the cleaning device, and the transmitting control circuit and the second coil are both arranged in the charging device.

Furthermore, the receiving control circuit is used to drive the first coil to work, and the transmitting control circuit is used to drive the second coil to work.

Furthermore, the second coil and the first coil are used to realize wireless charging of the cleaning device by the charging device, and the second coil and the first coil can also be used to realize information exchange between the charging device and the cleaning device.

Specifically, during operation, after the cleaning device approaches the charging device to align the signals of the first coil and the second coil, such as after the cleaning device completes its cleaning task and returns to the charging device, the receiving control circuit in the cleaning device obtains the cleaning device's operating information and encodes the obtained operating information. Specifically, the receiving control circuit adjusts the coil impedance of the first coil based on the cleaning device's operating information to modulate and superimpose the cleaning device's operating information on the impedance signal of the first coil. This change in the coil impedance of the first coil causes a change in the current in the second coil in the charging device, which then senses the coil impedance of the first coil and generates an induced current signal. Furthermore, the transmitting control circuit in the charging device reads the induced current signal and demodulates it to obtain a demodulation result, which is the cleaning device's operating information. Furthermore, based on the demodulation result of the induced current signal, which is the cleaning device's operating information, the transmitting control circuit controls the second coil to transmit a power transmission signal to the cleaning device, thereby providing charging power to the cleaning device via the power transmission signal. Furthermore, the transmission control circuit controls the charging device to perform tasks on the cleaning device based on the demodulated result of the induced current signal, i.e., the operating information of the cleaning device, such as controlling the charging device to collect dust from the cleaning device. Furthermore, the transmission control circuit can also adjust the amount of energy delivered to the cleaning device via the power transmission signal to control the charging status of the cleaning device.

Thus, on the one hand, one or more groups of first coils are provided in the cleaning device, and one or more groups of second coils are provided in the charging device. During the operation of the cleaning device, wireless charging of the cleaning device by the charging device is achieved through the method of electric-to-magnetic and magnetic-to-electric conversion. There are no metal contact points, which avoids the problem of being unable to charge the cleaning device due to oxidation and blackening of the metal pole piece, thereby improving the reliability and stability of charging the cleaning device. On the other hand, with the help of signal modulation and demodulation technology, the working information of the cleaning device is modulated on the impedance signal of the first coil at the cleaning device end, and the coil impedance of the first coil is sensed by the second coil at the charging device end to generate an induced current signal. Then, by demodulating the induced current signal, the working information of the cleaning device is obtained, thereby achieving communication interaction between the cleaning device and the charging device, avoiding the problem of communication failure due to signal blocking, inaccurate alignment, poor network quality, and poor communication environment, and improving the stability and reliability of communication interaction between the charging device and the cleaning device.

In some technical solutions, optionally, the receiving control circuit includes: a receiving control chip, used to detect the voltage and current information and working instruction information of the cleaning device, and determine the working information of the cleaning device based on the voltage and current information and the working instruction information; a modulation circuit, used to adjust the resonant cavity parameters of the first coil according to the working information to adjust the coil impedance of the first coil, and modulate the working information to be superimposed on the impedance signal of the first coil; the second coil is specifically used to: sense the impedance change information of the first coil, and generate an induced current signal based on the impedance change information, the impedance change information including the impedance change value and impedance change frequency of the first coil.

During the operation of the cleaning device, the receiving control chip is used to detect the working instruction information and voltage and current information of the cleaning device, and determine the working information of the cleaning device based on the detected working instruction information and voltage and current information.

Furthermore, the receiving control chip transmits the obtained working information to the modulation circuit, and the modulation circuit encodes the working information of the cleaning device. Specifically, the modulation circuit adjusts the resonant cavity parameters of the first coil based on the working information of the cleaning device to adjust the coil impedance of the first coil, and modulates the working information of the cleaning device and superimposes it on the impedance signal of the first coil. On this basis, the second coil can sense the impedance change information of the first coil, and generate an induced current signal based on the impedance change information, so as to subsequently obtain the working information of the cleaning device by analyzing the induced current signal. Among them, the above-mentioned impedance change information includes the impedance change value and impedance change frequency of the first coil. In this way, the signal-based modulation and demodulation technology realizes the communication interaction between the cleaning device and the charging device, avoids the problem of communication failure caused by signal blocking, inaccurate alignment, poor network quality and poor communication environment, and improves the stability and reliability of the communication interaction between the charging device and the cleaning device.

In some technical solutions, optionally, the transmission control circuit includes: a demodulation circuit, used to demodulate the induced current signal, determine the impedance change information of the first coil, and determine the working information of the cleaning device based on the impedance change information, the working information including the voltage and current information of the cleaning device; a transmission control chip, used to adjust the working frequency of the charging device according to the voltage and current information, so as to adjust the current on the second coil, and control the second coil to send a power transmission signal carrying charging power to the cleaning device; the first coil is also used to: sense the power transmission signal, generate a charging power signal, and charge the cleaning device through the charging power signal.

In this technical solution, the transmission control circuit may specifically include a demodulation circuit and a transmission control chip.

During operation, the demodulation circuit demodulates the induced current signal generated by the second coil to obtain impedance change information for the first coil. Based on this impedance change information, the cleaning device's operating information, including voltage and current information, is determined. Based on this information, the transmission control chip adjusts the operating frequency of the charging device based on the demodulated voltage and current information to adjust the current flowing through the second coil. This control controls the second coil to transmit a power transmission signal carrying charging power to the cleaning device, and controls the amount of energy delivered to the cleaning device via the power transmission signal, thereby controlling the charging of the cleaning device. Furthermore, the first coil senses the power transmission signal and generates a charging power signal, which is then used to charge the cleaning device. This signal-based modulation and demodulation technology enables communication between the cleaning device and the charging device, thereby controlling the charging parameters of the cleaning device. This improves the stability and reliability of communication between the charging device and the cleaning device, and enhances the reliability of charging the cleaning device.

In some technical solutions, optionally, the working information also includes working instruction information of the cleaning device, and the charging device also includes: a working component for performing working tasks; the transmission control chip is also used to: control the working component to work according to the working instruction information; wherein the working tasks include at least one of the following: dust collection tasks, cleaning tasks and drying tasks.

Furthermore, the charging device may also be equipped with working components, with different working components being used to perform different tasks. Based on this, after the demodulation circuit demodulates the working instruction information from the cleaning device, the transmission control chip can also control the working components in the charging device to operate according to this working instruction information, thereby performing tasks such as dust collection, cleaning, and drying on the cleaning device. In this way, signal-based modulation and demodulation technology enables communication and interaction between the cleaning device and the charging device, and further controls the charging device to perform tasks on the cleaning device. This improves the stability and reliability of communication and interaction between the charging and cleaning devices, and enhances the timeliness and accuracy of the charging device's execution of tasks.

In some technical solutions, optionally, when the signals of the first coil and the second coil are connected, the first coil at least partially overlaps with the second coil.

In this technical solution, when the charging device and cleaning device are brought close together to align the signals of the first and second coils, at least a portion of the second coil corresponds to the first coil. Specifically, at least a portion of the second coil overlaps the first coil. The greater the area of overlap between the second coil and the first coil, the more accurate the power wave transmission between the second coil and the first coil, and the more accurate the communication interaction between the charging device and the cleaning device.

In some technical solutions, optionally, the detection device includes: a first detection device, located inside the cleaning device, for detecting the voltage value of the charging port of the cleaning device; the control device includes: a first control device, located inside the cleaning device, electrically connected to the first detection device, for controlling the cleaning device to perform target work based on the first voltage value detected by the first detection device, wherein the first voltage value is the voltage value of the charging port when the charging device transmits power to the cleaning device.

The cleaning device provided in this application mainly includes a cleaning device, a charging device, a detection device and a control device, wherein the cleaning device can perform cleaning work or other work, and the charging device can provide electrical energy for the cleaning device. Furthermore, the detection device includes a first detection device, which is arranged inside the cleaning device, and the first detection device can detect the voltage value at the charging port of the cleaning device. The first detection device can be composed of a charging control circuit and can detect the power supply voltage input from the outside to the cleaning device. Furthermore, the control device includes a first control device, which is arranged inside the cleaning device and is electrically connected to the first detection device. When the voltage value detected by the first detection device is a first voltage value, wherein the first voltage value is the voltage value of the charging port when the charging device transmits power to the cleaning device, that is, when the first detection device detects that the charging device transmits power to the cleaning device, it means that the cleaning device has contacted the charging device at this time, that is, the cleaning device has reached the designated position. Therefore, when the first detection device detects the first voltage value, the first control device controls the cleaning device to perform the target work, wherein the target work can be charging, dust collection, rag washing, drying, etc. The present application sets a first detection device and a first control device in the cleaning device. When the first detection device detects that the charging device is charging the cleaning device, it indicates that the cleaning device has reached the specified position. Therefore, the first control device controls the cleaning device to perform the target work, thereby solving the problem in the related art that the cleaning device cannot sense that it has reached the specified position and cannot work normally due to damage and failure of the mechanical micro switch.

In some technical solutions, optionally, the first control device is also used to control the cleaning device to move toward the charging device and continue for a preset time based on when the first detection device detects a second voltage value, wherein the second voltage value is the voltage value of the charging port when the cleaning device is in contact with the charging device and the charging device does not transmit power to the cleaning device.

In this technical solution, when the voltage value detected by the first detection device is a second voltage value, the first control device controls the cleaning device to move toward the charging device and maintain this for a preset time, wherein the second voltage value is the voltage value of the charging port of the cleaning device when the cleaning device and the charging device are in contact and the charging device is not transmitting power to the cleaning device. In other words, when the first detection device detects that the cleaning device and the charging device are in contact, but the charging device has not yet transmitted power to the cleaning device, the cleaning device is controlled to move toward the charging device and maintain this for a preset time, thereby ensuring that the cleaning device and the charging device are in full contact. This application avoids the situation where an arc is generated between the charging device and the cleaning device due to insufficient contact between the charging device and the cleaning device by controlling the cleaning device to move toward the charging device for a preset time when contact occurs between the charging device and the cleaning device but the charging device has not yet transmitted power to the cleaning device, thereby avoiding the situation where an arc is generated between the charging device and the cleaning device due to insufficient contact between the charging device and the cleaning device, and avoids the situation where an arc is generated when the contact between the charging device and the cleaning device is in a charging state.

In some technical solutions, optionally, the cleaning equipment also includes: a battery, which is located inside the cleaning device and is used to provide electrical energy for the operation of the cleaning device; a first switch, which is electrically connected to the charging port and the battery respectively, and the first switch is communicatively connected to the first control device; the first control device is used to control the first switch to be in a closed state when the first detection device detects a first voltage value, so that the battery receives the electrical energy delivered by the charging device; the first control device is also used to control the first switch to be in an open state after the battery is charged.

In this technical solution, the cleaning device also includes a battery and a first switch. The battery is located within the cleaning device and is capable of receiving and storing electrical energy transmitted from the charging device to the cleaning device, thereby providing power to the cleaning device while it is performing cleaning or other tasks. The first switch is electrically connected to the charging port and the battery, respectively. Specifically, the first switch is located between the charging port and the battery. When the first switch is closed, the charging port and the battery are connected, allowing electrical energy received by the charging port to be transmitted to the battery. When the first switch is open, the charging port and the battery are disconnected, preventing the battery from receiving electrical energy from the charging port. When the first detection device detects a first voltage value, the first control device controls the first switch to be closed. Specifically, when the first detection device detects that the charging device is transmitting electrical energy to the cleaning device, the first control device controls the first switch to be closed, allowing the battery to receive electrical energy from the charging device. Otherwise, the first switch is open. By placing the first switch between the battery and the charging port and controlling the first switch to be closed only when the charging device is transmitting electrical energy to the cleaning device, the cleaning device is ensured to be safe to use.

Furthermore, when the battery is fully charged, the first control device controls the first switch to be in an off state, thereby terminating the power supply from the charging device to the cleaning device. By providing the first switch within the cleaning device, closing the first switch during charging and opening the first switch at the end of charging, the cleaning device is ensured to be safe to use.

In some technical solutions, optionally, the detection device includes: a second detection device, the second detection device is located inside the charging device, and is used to detect the voltage value of the power transmission port of the charging device; the control device includes: a second control device, located inside the charging device, electrically connected to the second detection device, and is used to control the charging device to supply electric energy to the cleaning device based on when the second detection device detects a third voltage value, wherein the third voltage value is the voltage value of the power transmission port when the cleaning device is in contact with the charging device and the charging device does not supply power to the cleaning device.

In this technical solution, the cleaning equipment primarily comprises a cleaning device, a charging device, a detection device, and a control device. The cleaning device is capable of performing cleaning or other tasks, and the charging device is capable of providing electrical energy to the cleaning device. The detection device includes a second detection device. The control device includes a second control device. Both the second detection device and the second control device are located within the charging device and are electrically connected to the second control device. The second detection device is capable of detecting the voltage at the charging device's power output port. The second detection device may comprise a circuit. When the second detection device detects a third voltage value, the second control device controls the charging device to supply electrical energy to the cleaning device. The third voltage value is the voltage at the charging device's power output port when the cleaning device and the charging device are in contact but not transmitting power to the cleaning device. In other words, when the second detection device detects contact between the cleaning device and the charging device, and the charging device is not transmitting power to the cleaning device, the second control device controls the charging device to supply power to the cleaning device, thereby achieving the technical effect of transferring electrical energy between the cleaning device and the charging device. For example, the second detection device may be a detection circuit.

In some technical solutions, optionally, the second control device is used to control the charging device to transmit electric energy to the cleaning device after a preset time delay based on the detection of the third voltage value by the second detection device, and the cleaning equipment also includes: a second switch, the second switch is electrically connected to the power transmission port, and the second switch is communicatively connected to the second control device; the second control device is used to control the second switch to be in a closed state after a preset time interval based on the detection of the third voltage value by the second detection device, so that the charging device transmits electric energy to the cleaning device.

In this technical solution, the second control device is specifically used to control the charging device to transmit electric energy to the cleaning device after a preset time delay based on the detection of the third voltage value by the second detection device. Specifically, when the second detection device detects contact between the cleaning device and the charging device, but the charging device has not yet transmitted power to the cleaning device, the charging device needs to wait for a preset time to allow sufficient contact between the charging device and the cleaning device. After waiting for the preset time, the charging device will transmit power to the cleaning device. This application arranges a second detection device inside the charging device. When the second detection device detects contact between the charging device and the cleaning device, it waits for a preset time to allow sufficient contact between the charging device and the cleaning device, and then controls the charging device to charge the cleaning device, thereby avoiding the situation where an arc is generated when the charging device transmits power to the cleaning device due to insufficient contact between the charging device and the cleaning device.

Specifically, the cleaning device also includes a second switch. The second switch is located within the charging device and is electrically connected to the power port. When the second switch is open, electricity cannot flow out of the charging device through the power port. When the second switch is closed, electricity can flow out of the charging device through the power port. The second switch is also in communication with a second control device, which can control the second switch to close or open. When the second detection device detects a third voltage value, the second control device controls the second switch to close after a preset time interval, thereby enabling the charging device to transmit power to the cleaning device through the power port, thereby transferring power from the charging device to the cleaning device. In other words, under normal circumstances, the second switch is open. When the second detection device detects contact between the charging device and the cleaning device, but the charging device has not yet transmitted power to the cleaning device, the second control device waits for a preset time to allow sufficient contact between the charging device and the cleaning device before controlling the second switch to close, thereby enabling power to be transmitted from the charging device to the cleaning device. The preset waiting time of the second control device is the same as the preset time that the cleaning device moves toward the charging device and continues to move. By providing the second switch, the second switch is controlled to be in a closed state only when the second detection device detects the third voltage value, thereby ensuring the safety of the charging device.

When the cleaning device is in contact with the charging device, the charging port of the cleaning device and the power transmission port of the charging device are connected through the metal pole piece. By utilizing the conductivity of the metal pole piece, the electric energy transmitted from the power transmission port of the charging device can enter the charging port of the cleaning device, thereby realizing the charging of the cleaning device by the charging device.

In this way, the communication interaction between the cleaning device and the charging device is realized based on the signal modulation and demodulation technology, avoiding the problem of communication failure caused by signal blocking, inaccurate alignment, poor network quality and poor communication environment, and improving the stability and reliability of the communication interaction between the charging device and the cleaning device.

In some technical solutions, optionally, the working information includes working instruction information of the cleaning device, and the charging device is controlled to perform working tasks on the cleaning device according to the working information, including: controlling the working components in the charging device to perform working tasks on the cleaning device according to the working instruction information; wherein the working tasks include at least one of the following: dust collection tasks, cleaning tasks, and drying tasks.

In this technical solution, the demodulated result of the induced current signal, i.e., the operating information of the cleaning device, may include the operating instruction information of the cleaning device. Based on this, when the control device of the cleaning device controls the charging device to perform the operating task of the cleaning device based on the demodulated result, i.e., the operating information of the cleaning device, the control device of the cleaning device controls the operating components of the charging device to operate according to the aforementioned operating instruction information, thereby performing dust collection, cleaning, and drying tasks on the cleaning device. In this way, signal-based modulation and demodulation technology enables communication and interaction between the cleaning device and the charging device, thereby controlling the charging device to perform the operating task on the cleaning device. This improves the stability and reliability of communication and interaction between the charging device and the cleaning device, and enhances the timeliness and accuracy of the charging device's execution of the operating task.

In some technical solutions, optionally, the working information includes voltage and current information of the cleaning device, and the second coil is controlled to send a power transmission signal to the cleaning device according to the working information, including: adjusting the working frequency of the charging device according to the voltage and current information to adjust the current size on the second coil in the charging device, and controlling the second coil to send a power transmission signal carrying charging power to the cleaning device.

In this technical solution, the demodulated result of the induced current signal, i.e., the operating information of the cleaning device, can also include voltage and current information of the cleaning device. Based on this, when the cleaning device's control device controls the second coil to transmit a power transmission signal to the cleaning device based on the demodulated result, i.e., the operating information of the cleaning device, the control device controls the transmitter control chip to perform a full-bridge inverter output based on the demodulated voltage and current information. This adjusts the operating frequency of the charging device to adjust the current in the second coil, controls the second coil to transmit a power transmission signal carrying charging power to the cleaning device, and controls the amount of energy transferred to the cleaning device via the power transmission signal, thereby controlling the charging of the cleaning device. Based on this, the first coil can sense the power transmission signal and generate a charging power signal, which is then used to charge the cleaning device. In this way, signal modulation and demodulation technology enables communication between the cleaning device and the charging device, thereby controlling the charging parameters of the cleaning device. This improves the stability and reliability of communication between the charging device and the cleaning device, and enhances the reliability of charging the cleaning device.

In some technical solutions, optionally, the cleaning device and/or charging device is controlled to work according to the working information, including: obtaining the voltage value detected by the first detection device in the cleaning device; when the voltage value detected by the first detection device is a first voltage value, controlling the cleaning device to perform the target work, wherein the first voltage value is the voltage value of the charging port of the cleaning device when the charging device transmits power to the cleaning device.

In this technical solution, controlling the cleaning device and/or charging device to operate based on operating information includes: obtaining a voltage value detected by a first detection device within the cleaning device. Since the first detection device detects the voltage value of the charging port of the cleaning device, obtaining the voltage value detected by the first detection device can determine the operating status between the cleaning device and the charging device. When the voltage value detected by the first detection device is a first voltage value, the cleaning device is controlled to perform a target operation, wherein the first voltage value is the voltage value of the charging port of the cleaning device when the charging device transmits power to the cleaning device. In other words, after obtaining the voltage value detected by the first detection device, the voltage value is analyzed. When the analysis shows that the voltage value represents contact between the cleaning device and the charging device, and that the charging device transmits power to the cleaning device, indicating that the cleaning device has reached the designated position, the cleaning device is controlled to perform the target operation, wherein the target operation can be charging, dust collection, rag washing, drying, and other actions. The present application obtains the voltage value detected by the first detection device. When the detected voltage value is the voltage value of the charging port when the charging device transmits power to the cleaning device, it indicates that the cleaning device has reached the specified position. Therefore, the cleaning device is controlled to perform the target work, thereby solving the problem in the related art that the cleaning device cannot sense that it has reached the specified position and cannot work normally due to damage and failure of the mechanical micro switch.

In some technical solutions, optionally, controlling the cleaning device and/or charging device to work according to working information also includes: when the voltage value detected by the first detection device is a second voltage value, controlling the cleaning device to move toward the charging device and continuing for a preset time, wherein the second voltage value is the voltage value of the charging port when the cleaning device is in contact with the charging device and the charging device does not transmit power to the cleaning device.

In this technical solution, controlling the cleaning device and/or charging device to operate based on the operating information further includes: when the voltage value detected by the first detection device is a second voltage value, which is the voltage value of the charging port when the cleaning device and the charging device are in contact and the charging device is not transmitting power to the cleaning device, controlling the cleaning device to move toward the charging device for a preset time, thereby enabling repeated contact between the cleaning device and the charging device. In other words, when the voltage value detected by the first detection device determines that the current operating state between the cleaning device and the charging device is contact between the cleaning device and the charging device, but the charging device is not transmitting power to the cleaning device, controlling the cleaning device to move toward the charging device for a preset time, thereby ensuring sufficient contact between the charging device and the cleaning device before the charging device transmits power to the cleaning device, thereby avoiding arcing caused by insufficient contact between the charging device and the cleaning device when the charging device transmits power to the cleaning device, and avoiding arcing caused by contact between the charging device and the cleaning device when the charging device and the cleaning device are in a charging state. For example, the preset time during which the cleaning device moves toward the charging device and remains in contact can be the same as the preset time the charging device waits before transmitting power to the cleaning device.

In some technical solutions, optionally, the step of controlling the cleaning device to perform a target task includes: determining the target task; and when the target task is charging, controlling a first switch in the cleaning device to be in a closed state so that the cleaning device receives electrical energy delivered by the charging device.

In this technical solution, the step of controlling the cleaning device to perform the target work includes: first determining the specific content of the target work. For example, the specific content of the target work can be charging, dust collection, rag washing, drying, etc. When the target work is charging, the first switch in the cleaning device is controlled to be in a closed state, so that the cleaning device can receive the electric energy transmitted by the charging device. Since the first switch is connected to the battery, when the target work is charging and the first detection device detects the first voltage value, the first switch is controlled to be in a closed state, thereby realizing charging of the battery. And since the first switch is controlled to be closed only when charging, the safety of the battery of the cleaning device can also be guaranteed when the cleaning device is performing other work.

In some technical solutions, optionally, the control method of the cleaning device further includes: controlling a first switch in the cleaning device to be in a closed state based on the voltage value detected by the first detection device being a first voltage value.

In this technical solution, the control method for the cleaning device further includes: when the voltage value detected by the first detection device is a first voltage value, where the first voltage value is the voltage value of the charging port when the charging device is transmitting power to the cleaning device, that is, when the operating state between the charging device and the cleaning device is that the charging device is transmitting power to the cleaning device, controlling a first switch in the cleaning device to be closed. The first switch in the cleaning device connects the charging port of the cleaning device and the battery, respectively. By controlling the first switch to be closed, the battery in the cleaning device can receive the power transmitted by the charging device, thereby completing the charging process of the cleaning device. Simultaneously, during the charging process, it is necessary to monitor the voltage value detected by the first detection device in real time. When the voltage value detected by the first detection device is not the first voltage value, indicating that the charging device has stopped transmitting power to the cleaning device, or the voltage transmitted by the charging device to the cleaning device exceeds a limit, the first switch is controlled to be opened, thereby stopping the battery from continuing to receive power from the charging device. By controlling the opening and closing of the first switch, the safety of the battery is protected.

In some technical solutions, optionally, the control method of the cleaning device further includes: obtaining the working status of a battery in the cleaning device; and controlling the first switch to be in an off state based on the working status of the battery being charging completed.

In this technical solution, the control method for a cleaning device further includes: obtaining the operating status of a battery within the cleaning device in real time, where the battery operating status is selected as uncharged, charging, and fully charged. When the battery operating status indicates fully charged, indicating that the battery no longer requires further power from the charging device, the first switch is controlled to open, thereby terminating the charging operation of the cleaning device. By controlling the first switch to open after battery charging is complete, the battery is protected.

In some technical solutions, optionally, the cleaning device and/or the charging device are controlled to operate according to the working information, including: obtaining the voltage value detected by the second detection device in the charging device; when the voltage value detected by the second detection device is a third voltage value, controlling the charging device to transmit electric energy to the cleaning device, wherein the third voltage value is the voltage value of the power transmission port of the charging device when the cleaning device is in contact with the charging device and the charging device is not transmitting power to the cleaning device.

In this technical solution, controlling the operation of the cleaning device and/or the charging device based on the operating information includes: obtaining a voltage value detected by a second detection device within the charging device. Since the second detection device detects the voltage value at the power transmission port of the charging device, the voltage value detected by the second detection device can be used to determine the operating status between the charging device and the cleaning device based on the voltage value. When the voltage value detected by the second detection device is a third voltage value, which is the voltage value at the power transmission port of the charging device when the cleaning device and the charging device are in contact and the charging device is not transmitting power to the cleaning device, the charging device is controlled to transmit power to the cleaning device. In other words, after obtaining the voltage value detected by the second detection device, when it is determined based on the obtained voltage value that the current operating status between the charging device and the cleaning device is contact between the charging device and the cleaning device but the charging device is not transmitting power to the cleaning device, the charging device is controlled to transmit power to the cleaning device, thereby achieving the technical effect of transmitting electrical energy between the cleaning device and the charging device.

In some technical solutions, optionally, the step of controlling the charging device to deliver electric energy to the cleaning device includes: controlling the charging device to deliver electric energy to the cleaning device after a preset time delay; the step of controlling the charging device to deliver electric energy to the cleaning device after a preset time delay includes: determining a first time when the voltage value detected by the second detection device is a third voltage value; determining a second time based on the first time and the preset time; and controlling the second switch in the charging device to be in a closed state based on when the time reaches the second time.

In this technical solution, the step of controlling the charging device to supply electrical energy to the cleaning device specifically includes: controlling the charging device to delay supplying electrical energy to the cleaning device for a preset time. Specifically, when the voltage value detected by the second detection device is a third voltage value, controlling the charging device to delay supplying electrical energy to the cleaning device for a preset time. The third voltage value is the voltage value at the power transmission port of the charging device when the charging device and the cleaning device are in contact but the charging device is not transmitting electrical energy to the cleaning device. In other words, when the second detection device detects the third voltage value, indicating that the charging device and the cleaning device are in contact but the charging device is not transmitting electrical energy to the cleaning device, the device waits for a preset time to allow sufficient contact between the charging device and the cleaning device, and then controls the charging device to supply electrical energy to the cleaning device. This application ensures sufficient contact between the charging device and the cleaning device by waiting for a preset time before controlling the charging device to supply electrical energy to the cleaning device when the operating state between the cleaning device and the charging device is that the cleaning device and the charging device are in contact but the charging device is not transmitting electrical energy to the cleaning device. This avoids arcing caused by insufficient contact between the charging device and the cleaning device when the charging device transmits electrical energy to the cleaning device.

Furthermore, the step of controlling the charging device to delay the transmission of electrical energy to the cleaning device for a preset time specifically includes: first, determining the time when the second detection device detects the third voltage value as a first time; then, deriving a second time based on the first time and the preset time, that is, delaying the first time by the preset time to obtain the second time; and when the second time is reached, controlling the second switch in the charging device to be closed, thereby enabling the charging device to transmit power to the cleaning device. In other words, after the second detection device detects the third voltage value, it is necessary to wait for a preset time to allow sufficient contact between the charging device and the cleaning device to prevent arcing between the two devices. After the preset time, controlling the second switch to close, allowing electrical energy to flow out of the power transmission port through the second switch to charge the cleaning device. By closing the second switch only when the charging device is transmitting power to the cleaning device, the safe use of the charging device is also ensured.

For example, the control unit controls the cleaning device to perform cleaning work, or the control unit controls the charging device to charge the cleaning device, etc. In this way, based on the operating information of the cleaning device or the charging device, the cleaning device and/or the charging device are controlled to operate, thereby ensuring the reliability of the operation of the cleaning device and/or the charging device, thereby ensuring the accuracy of the reliability of the operation of the cleaning equipment.

DETAILED DESCRIPTION

In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

1 to 17 , the cleaning device and its control method and device, electronic device, and readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

In one embodiment of the present application, a cleaning device is provided. As shown in Figures 1, 2, and 8, cleaning device 100 includes a charging device 102 and a cleaning device 104. Charging device 102 is capable of charging cleaning device 104, and the charging device 102 and cleaning device 104 are capable of communicating with each other.

Furthermore, as shown in FIG1 , FIG2 and FIG8 , the cleaning device 100 further includes a detection device 140 , which is disposed in the cleaning device 104 and/or the charging device 102 , and is used to detect working information of the cleaning device 104 or the charging device 102 .

Furthermore, as shown in Figures 2 and 8, the cleaning device 100 also includes a control device 134, which is arranged in the cleaning device 104 and/or the charging device 102. The control device 134 can control the cleaning device 104 and/or the charging device 102 to work based on the working information detected by the detection device 140.

Specifically, during operation of cleaning device 100, detection device 140 detects operating information of cleaning device 104 or charging device 102, and control device 134 controls the operation of cleaning device 104 and/or charging device 102 based on the operating information. For example, control device 134 controls cleaning device 104 to perform cleaning operations, and controls charging device 102 to charge cleaning device 104. In this way, based on the operating information of cleaning device 104 or charging device 102, the operation of cleaning device 104 and/or charging device 102 is controlled, ensuring the reliability of the operation of cleaning device 104 and/or charging device 102, thereby ensuring the reliability and accuracy of the operation of cleaning device 100.

In some embodiments of the present application, optionally, as shown in FIG1 , the detection device 140 may specifically include a first coil 108 and a second coil 106, and as shown in FIG2 and FIG17 , the control device 134 may specifically include a receiving control circuit 112 and a transmitting control circuit 110. As shown in FIG2 , the transmitting control circuit 110 and the second coil 106 are both disposed within the charging device 102, and the receiving control circuit 112 and the first coil 108 are both disposed within the cleaning device 104. Furthermore, the transmitting control circuit 110 is configured to drive the second coil 106 to operate, and the receiving control circuit 112 is configured to drive the first coil 108 to operate.

Furthermore, both the second coil 106 and the first coil 108 are wireless coils. When the charging device 102 and the cleaning device 104 are close to each other, the second coil 106 and the first coil 108 can overlap, thereby achieving signal connection. Furthermore, the second coil 106 and the first coil 108 are used to enable wireless charging of the cleaning device 104 by the charging device 102.

Specifically, one or more sets of second coils 106 are provided within charging device 102, and one or more sets of first coils 108 are provided within cleaning device 104. When charging device 102 is used to charge cleaning device 104, when second coils 106 and first coils 108 overlap, second coils 106 within charging device 102 act as transmitting coils to generate a magnetic field, while first coils 108 within cleaning device 104 act as receiving coils to receive the magnetic field and generate a voltage. Thus, when cleaning device 104 is close to charging device 102, cleaning apparatus 100 can wirelessly charge cleaning device 104 using second coils 106 and first coils 108, using electrical-to-magnetic and magnetic-to-electrical conversion methods.

In actual use, as shown in FIG2 , the charging device 102 may also be provided with a power supply and an MCU (Micro Control Unit), and the cleaning device 104 may also be provided with an MCU, a battery, and a main control board. When the cleaning device 104 is wirelessly charged by the charging device 102, the power supply and MCU within the charging device 102 drive the second coil 106 to perform an electro-magnetic conversion operation. The voltage generated by the first coil 108 charges the battery, thereby providing energy to the MCU and the main control board.

Furthermore, the second coil 106 and the first coil 108 can also be used to implement information exchange between the charging device 102 and the cleaning device 104, so that the cleaning device 100 can control the charging device 102 to charge the cleaning device 104 based on the interactive information between the charging device 102 and the cleaning device 104, and control the charging device 102 to perform dust collection, cleaning, drying, and other operations on the cleaning device 104. Specifically, in addition to driving the first coil 108 to operate, the receiving control circuit 112 can also superimpose the interactive information from the cleaning device 104 to the charging device 102 on the first coil 108 through signal modulation, thereby transmitting the interactive information from the cleaning device 104 to the charging device 102 to the charging device 102 via the first coil 108.

Specifically, for the cleaning device 100 provided in this application, during the operation of the cleaning device 100, when the cleaning device 104 is close to the charging device 102 so that the signals of the first coil 108 and the second coil 106 are connected, such as when the cleaning device 104 completes the cleaning task and returns to the charging device 102, the receiving control circuit 112 in the cleaning device 104 will obtain the working information of the cleaning device 104 and encode the obtained working information. Specifically, the receiving control circuit 112 adjusts the coil impedance of the first coil 108 according to the working information of the cleaning device 104 to modulate the working information of the cleaning device 104 and superimpose it on the impedance signal of the first coil 108. On this basis, the change in the coil impedance of the first coil 108 will cause the current in the second coil 106 in the charging device 102 to change. The second coil 106 senses the coil impedance of the first coil 108 and generates an induced current signal. Further, the transmitting control circuit 110 on the charging device 102 reads the induced current signal and demodulates the induced current signal to obtain the demodulation result, which is the working information of the cleaning device 104. Furthermore, based on the demodulated result of the induced current signal, i.e., the operating information of the cleaning device 104, the transmission control circuit 110 controls the second coil 106 to transmit a power transmission signal to the cleaning device 104, thereby providing charging power to the cleaning device 104 via the power transmission signal. Furthermore, based on the demodulated result of the induced current signal, i.e., the operating information of the cleaning device 104, the transmission control circuit 110 controls the charging device 102 to perform a task on the cleaning device 104, such as controlling the charging device 102 to collect dust from the cleaning device 104. Furthermore, the transmission control circuit 110 can also adjust the amount of energy transmitted to the cleaning device 104 via the power transmission signal to control the charging status of the cleaning device 104.

The aforementioned operating information may specifically include information related to the charging of the cleaning device 104, such as voltage information, current information, power information, overvoltage information, undervoltage information, overcurrent information, and over-temperature protection information. After the transmission control circuit 110 controls the second coil 106 to transmit a power transmission signal to the cleaning device 104 based on the operating information of the cleaning device 104, the charging status of the cleaning device 104 can be controlled, such as the voltage, current, and power used to charge the cleaning device 104.

Furthermore, the aforementioned operation information may specifically include task instructions that the cleaning device 104 requires the charging device 102 to perform, such as dust collection instructions, cloth cleaning instructions, and drying instructions. The transmission control circuit 110 controls the charging device 102 to operate according to the operation information of the cleaning device 104, and can control the charging device 102 to perform tasks such as dust collection, cloth cleaning, and drying for the cleaning device 104.

It is understandable that most existing cleaning devices with charging devices are charged by using a metal electrode contact conductive method, and the cleaning device and the charging device use an infrared module or a radio frequency module for communication and interaction. However, the metal electrode will oxidize and turn black over time, resulting in poor contact of the metal electrode and the inability to charge the cleaning device, which reduces the reliability and stability of the charging of the cleaning device. As for the communication and interaction between the charging device and the cleaning device, when the charging device and the cleaning device communicate through the infrared module, there will be problems of communication failure or signal loss due to dust on the surface of the charging device and the cleaning device or the infrared modules of the charging device and the cleaning device are not precisely aligned. When the charging device and the cleaning device communicate through a radio frequency module such as a 2.4GHz WIFI module, a 5GHz WIFI module, a Bluetooth module, a 433MHz module, and a LoRa module, there will be problems of communication failure or signal loss due to factors such as network quality and communication environment such as partitions or corners, which reduces the reliability of the interaction between the charging device and the cleaning device.

Therefore, the cleaning device 100 provided in the present application, on the one hand, is provided with one or several groups of second coils 106 in the charging device 102, and one or several groups of first coils 108 in the cleaning device 104. During the operation of the cleaning device 100, the charging device 102 wirelessly charges the cleaning device 104 through electric-to-magnetic and magnetic-to-electric methods. There is no metal contact point, which avoids the problem of being unable to charge the cleaning device 104 due to oxidation and blackening of the metal pole piece, thereby improving the reliability and stability of charging the cleaning device 104. On the other hand, with the help of signal modulation and demodulation technology, the working information of the cleaning device 104 is modulated on the impedance signal of the first coil 108 at the cleaning device 104 end, and the coil impedance of the first coil 108 is induced by the second coil 106 at the charging device 102 end to generate an induced current signal, and then the working information of the cleaning device 104 is obtained by demodulating the induced current signal, thereby realizing communication interaction between the cleaning device 104 and the charging device 102, avoiding the problem of communication failure caused by signal blocking, inaccurate alignment, poor network quality and poor communication environment, and improving the stability and reliability of communication interaction between the charging device 102 and the cleaning device 104.

In some embodiments of the present application, optionally, as shown in FIG17 , the receiving control circuit 112 may specifically include a receiving control chip 144 and a modulation circuit 146. During operation of the cleaning device 100, the receiving control chip 144 is configured to detect operating instruction information and voltage and current information of the cleaning device 104, and determine operating information of the cleaning device 104 based on the detected operating instruction information and voltage and current information.

Furthermore, the receiving control chip 144 transmits the obtained operating information to the modulation circuit 146, which encodes the operating information of the cleaning device 104. Specifically, the modulation circuit 146 adjusts the resonant cavity parameters of the first coil 108 based on the operating information of the cleaning device 104 to adjust the coil impedance of the first coil 108, modulating the operating information of the cleaning device 104 and superimposing it on the impedance signal of the first coil 108. Based on this, the second coil 106 can sense the impedance change information of the first coil and generate an induced current signal based on this impedance change information, so that the operating information of the cleaning device can be subsequently obtained by analyzing the induced current signal. The impedance change information mentioned above includes the impedance change value and impedance change frequency of the first coil 108.

It is understood that the modulation circuit 146 adjusts the resonant cavity parameters of the first coil 108, thereby changing the impedance of the first coil 108. This change in the impedance of the first coil 108, in turn, changes the current flowing through the second coil 106. Thus, the transmission control circuit 110 in the charging device 102 can determine the impedance change of the first coil 108 by measuring and analyzing the current flowing through the second coil 106, thereby demodulating and obtaining operating information of the cleaning device 104. In this way, signal-based modulation and demodulation technology enables communication between the cleaning device 104 and the charging device 102, avoiding communication failures caused by signal obstruction, inaccurate alignment, poor network quality, and a poor communication environment, thereby improving the stability and reliability of communication between the charging device 102 and the cleaning device 104.

In actual application, the above-mentioned work instruction information is specifically a task instruction that the cleaning device 104 requires the charging device 102 to execute, such as a dust collection instruction, a rag cleaning instruction, and a drying instruction, etc., which is not specifically limited here.

Furthermore, the receiving control chip 144 can also detect power information, overvoltage information, undervoltage information, overcurrent information, and over-temperature protection information of the cleaning device 104, and modulate and superimpose this information on the impedance signal of the first coil 108. In this way, the cleaning device 104 can control parameters such as the energy level, voltage level, current level, and power level of the charging device 102, while also implementing functions such as overvoltage protection, overcurrent protection, and over-temperature protection for the cleaning device 104.

In some embodiments of the present application, optionally, as shown in FIG. 17 , the transmit control circuit 110 may specifically include a demodulation circuit 150 and a transmit control chip 148 .

During operation of the cleaning device 100, the demodulation circuit 150 demodulates the induced current signal generated by the second coil 106 to obtain impedance change information of the first coil 108. Based on this impedance change information, the operating information of the cleaning device 104, including voltage and current information of the cleaning device 104, is determined. Based on this information, the transmission control chip 148 performs full-bridge inversion output based on the demodulated voltage and current information, thereby adjusting the operating frequency of the charging device 102, thereby adjusting the current in the second coil 106, controlling the second coil 106 to transmit a power transmission signal carrying charging power to the cleaning device 104, and controlling the amount of energy transferred to the cleaning device 104 via the power transmission signal, thereby controlling the charging status of the cleaning device 104. Based on this, the first coil 108 can sense the power transmission signal and generate a charging power signal, which is used to charge the cleaning device. In this way, the signal-based modulation and demodulation technology realizes the communication interaction between the cleaning device 104 and the charging device 102, thereby controlling the charging parameters of the cleaning device 104, improving the stability and reliability of the communication interaction between the charging device 102 and the cleaning device 104, and improving the reliability of charging the cleaning device 104.

In actual application, the impedance signal of the first coil may also carry power information, overvoltage information, undervoltage information, overcurrent information, and over-temperature protection information of the cleaning device 104. The transmitting control core may adjust the operating frequency of the charging device 102 according to the above information, thereby controlling the energy, voltage, current, and power parameters of the charging device 102 for charging the cleaning device 104, thereby realizing functions such as overvoltage protection, overcurrent protection, and over-temperature protection of the cleaning device 104.

In some embodiments of the present application, optionally, the demodulation result of the induced current signal may also include work instruction information of the cleaning device 104, and the work instruction information is specifically the task instruction that the cleaning device 104 requires the charging device 102 to perform, such as dust collection instruction, rag cleaning instruction, and drying instruction, etc., which is not specifically limited here.

Furthermore, as shown in FIG2 , the charging device 102 may also be provided with working components 142 such as a dust bag, a water tank, a water tank, and a drying device, with different working components 142 being used to perform different work tasks. On this basis, after the demodulation circuit 150 demodulates and obtains the above-mentioned work instruction information, the transmission control chip 148 may also control the working components 142 in the charging device 102 to operate according to the above-mentioned work instruction information, so as to perform dust collection tasks, cleaning tasks, and drying tasks on the cleaning device 104. In this way, signal-based modulation and demodulation technology enables communication and interaction between the cleaning device 104 and the charging device 102, thereby controlling the charging device 102 to perform work tasks on the cleaning device 104, thereby improving the stability and reliability of communication and interaction between the charging device 102 and the cleaning device 104, and improving the timeliness and accuracy of the charging device 102 in performing work tasks.

In some embodiments of the present application, optionally, when the charging device 102 and the cleaning device 104 are brought into proximity so that the first coil 108 and the second coil 106 are connected in signal connection, at least a portion of the second coil 106 and the first coil 108 correspond to each other. Specifically, at least a portion of the second coil 106 and the first coil 108 overlap. The greater the area of overlap between the second coil 106 and the first coil 108, the higher the accuracy of power wave transmission between the second coil 106 and the first coil 108, and the higher the accuracy of communication and interaction between the charging device 102 and the cleaning device 104.

In some embodiments of the present application, optionally, as shown in FIG8 , a cleaning device 100 primarily includes a cleaning device 104, a charging device 102, a detection device 140, and a control device 134. The cleaning device 104 is capable of performing cleaning or other tasks, and the charging device 102 is capable of providing electrical energy to the cleaning device 104. The detection device 140 includes a first detection device 132, which is disposed within the cleaning device 104 and is capable of detecting the voltage at a charging port 138 of the cleaning device 104. The first detection device 132 may comprise a charging control circuit capable of detecting the external power supply voltage input to the cleaning device 100. The control device 134 includes a first control device 136, which is disposed within the cleaning device 104 and is electrically connected to the first detection device 132.

When the voltage value detected by the first detection device 132 is the first voltage value, wherein the first voltage value is the voltage value of the charging port 138 when the charging device 102 transmits power to the cleaning device 104, that is, when the first detection device 132 detects that the charging device 102 transmits power to the cleaning device 104, it means that the cleaning device 104 is in contact with the charging device 102 at this time, that is, it means that the cleaning device 104 has reached the designated position. Therefore, when the first detection device 132 detects the first voltage value, the first control device 136 controls the cleaning device 104 to perform the target work, wherein the target work can be charging, dust collection, rag washing, drying and other actions.

It is understandable that household sweepers are currently widely used. As shown in Figure 7, the sweeper is in contact with the charging device through a microswitch. The triggering of the mechanical microswitch on the sweeper or base station (charging device) indicates that the sweeper has reached the designated position. After detecting that it has reached the designated position, the sweeper or base station starts charging, dust collection, cloth washing, drying, etc. However, the mechanical microswitch is prone to water corrosion or fatigue damage, which may cause the mechanical microswitch to be constantly triggered or unable to be triggered, thus making the sweeper unable to work properly.

Specifically, Figure 7 shows a schematic diagram of the structure of a cleaning device in the related art. As shown in Figure 7, current cleaning devices detect when a cleaning device (i.e., a sweeper) has reached a designated position by installing a mechanical microswitch on the cleaning device or charging device. When the mechanical switch is triggered, it indicates that the cleaning device (i.e., the sweeper) has reached the designated position, and the cleaning device or charging device begins charging, collecting dust, washing cloths, drying clothes, and other operations. However, the cleaning device in Figure 7 has the following disadvantages: 1. The mechanical microswitch is susceptible to water corrosion or fatigue damage, which can cause the mechanical microswitch to be constantly triggered or unable to be triggered, disrupting the charging, dust collection, cloth washing, drying, and other functions of the cleaning device and preventing them from functioning properly. 2. Communication between the charging and cleaning devices typically utilizes a radio frequency module or an infrared module. When the microswitch is placed on the charging device and communication between the two devices fails, the charging device cannot notify the cleaning device that the microswitch has been triggered, disrupting the charging, dust collection, cloth washing, drying, and other functions of the cleaning device and preventing them from functioning properly.

Based on this, the present application sets a first detection device 132 and a first control device 136 in the cleaning device 104. When the first detection device 132 detects that the charging device 102 is charging the cleaning device 104, it indicates that the cleaning device 104 has reached the specified position. Therefore, the first control device 136 controls the cleaning device 104 to perform the target work, thereby solving the problem in the related art that the cleaning device 104 cannot sense that it has reached the specified position and cannot work normally due to damage and failure of the mechanical micro switch.

In some embodiments, optionally, the first control device 136 is further configured to control the cleaning device 104 to move toward the charging device 102 for a predetermined period of time based on the detection of a second voltage value by the first detection device 132, so as to ensure full contact between the charging device 102 and the cleaning device 104. The second voltage value is the voltage value of the charging port 138 when the cleaning device 104 is in contact with the charging device 102 and the charging device 102 is not transmitting power to the cleaning device 104. That is to say, when the first detection device 132 detects that contact occurs between the cleaning device 104 and the charging device 102, but at this time the charging device 102 has not yet transmitted power to the cleaning device 104, the cleaning device 104 is controlled to move toward the charging device 102 and continue for a preset time, so that sufficient contact is made between the cleaning device 104 and the charging device 102. This application avoids the situation where an arc is generated between the charging device 102 and the cleaning device 104 due to insufficient contact between the charging device 102 and the cleaning device 104 by controlling the cleaning device 104 to move toward the charging device 102 for a preset time when contact occurs between the charging device 102 and the cleaning device 104 but the charging device 102 has not yet transmitted power to the cleaning device 104, thereby avoiding the situation where an arc is generated between the charging device 102 and the cleaning device 104 when the contact is in the charging state.

In some embodiments, as shown in FIG8 , the cleaning device 100 optionally further includes a battery 114 and a first switch 116 . Battery 114 is disposed within the cleaning device 104 and is capable of receiving electrical energy transmitted from the charging device 102 to the cleaning device 104 and storing the received electrical energy, thereby providing electrical energy to the cleaning device 104 while performing cleaning or other tasks. First switch 116 is electrically connected to the charging port 138 and the battery 114 , respectively. Specifically, first switch 116 is located between the charging port 138 and the battery 114 . When the first switch 116 is closed, the charging port 138 is connected to the battery 114 , allowing the electrical energy received by the charging port 138 to be transferred to the battery 114 . When the first switch 116 is open, the charging port 138 is disconnected from the battery 114 , preventing the battery 114 from receiving electrical energy from the charging port 138 . First switch 116 is communicatively connected to first control device 136. When first detection device 132 detects a first voltage value (the first voltage value is the voltage at charging port 138 when charging device 102 is transmitting power to cleaning device 104), first control device 136 controls first switch 116 to close, thereby enabling battery 114 to receive power from charging device 102. In other circumstances, first switch 116 is open. However, when charging device 102 is transmitting power to cleaning device 104, first switch 116 is controlled to close, thereby charging battery 114. By placing first switch 116 between battery 114 and charging port 138 and controlling first switch 116 to close only when charging device 102 is transmitting power to cleaning device 104, safe operation of cleaning device 104 is ensured.

Furthermore, when the battery 114 is fully charged, the first control device 136 controls the first switch 116 to be in an off state, thereby terminating the power transmission from the charging device 102 to the cleaning device 104. By providing the first switch 116 within the cleaning device 104, closing the first switch 116 during charging, and opening the first switch 116 at the end of charging, the safe use of the cleaning device 104 is ensured.

In some embodiments, optionally, as shown in FIG8 , the detection device 140 includes a second detection device 118 . The control device 134 includes a second control device 120 . The second detection device 118 and the second control device 120 are both located inside the charging device 102 , and the second detection device 118 is electrically connected to the second control device 120 . The second detection device 118 is capable of detecting the voltage value at the power transmission port 130 of the charging device 102 . The second detection device 118 may be composed of a circuit. The second control device 120 is configured to control the charging device 102 to transmit electrical energy to the cleaning device 104 based on a third voltage value detected by the second detection device 118 . The third voltage value is the voltage value at the power transmission port 130 of the charging device 102 when the cleaning device 104 and the charging device 102 are in contact but the charging device 102 is not transmitting power to the cleaning device 104 . That is, when the second detection device 118 detects contact between the cleaning device 104 and the charging device 102, and the charging device 102 has not yet transmitted power to the cleaning device 104, the second control device 120 controls the charging device 102 to transmit power to the cleaning device 104, thereby achieving the technical effect of transferring electrical energy between the cleaning device 104 and the charging device 102. For example, the second detection device 118 may be a detection circuit. In some embodiments, optionally, when the second detection device 118 detects a third voltage value, the second control device 120 controls the charging device 102 to transmit power to the cleaning device 104 after a preset delay. Specifically, when the second detection device 118 detects contact between the cleaning device 104 and the charging device 102, but the charging device 102 has not yet transmitted power to the cleaning device 104, the charging device 102 waits for a preset time to allow sufficient contact between the charging device 102 and the cleaning device 104. Only after the preset waiting time does the charging device 102 transmit power to the cleaning device 104.

Understandably, household vacuum cleaners are now widely used. As shown in Figure 1, the vacuum cleaner is charged through metal electrodes that contact the charging device. Both the vacuum cleaner and the charging device have metal electrodes. When the vacuum cleaner detects that it is ready to charge, it turns on the charging function. During the charging process, if the vacuum cleaner encounters unreliable contact, the metal electrodes will rub and spark, generating an arc. Over time, the metal electrodes will turn black, resulting in poor contact and failure to charge.

Specifically, as shown in FIG7 , in the related art, a mechanical microswitch is installed on the cleaning device or the charging device. When the mechanical microswitch is triggered, it indicates that the cleaning device is in place and the cleaning device can turn on the charging switch. However, the cleaning device in FIG7 has the following disadvantages: 1. After the mechanical microswitch is triggered, the sweeper starts charging. At this time, the metal electrode may not be fully in contact and has entered the charging state, and the metal electrode will spark and produce an arc. 2. Because the mechanical microswitch has a stroke problem, the sweeper shakes or is displaced by external force during charging, and the mechanical microswitch is released. At this time, the sweeper will retreat toward the charging device. During this process, the metal electrode will rub and spark to produce an arc. 3. The mechanical microswitch is likely to be corroded by water or damaged by fatigue, causing the mechanical microswitch to be triggered all the time. Charging is turned on before the sweeper and the charging device come into contact. At this time, the contact of the metal terminals will rub and spark to produce an arc.

Based on this, the present application sets a second detection device 118 inside the charging device 102. When the second detection device 118 detects that the charging device 102 and the cleaning device 104 are in contact with each other, it waits for a preset time to allow the charging device 102 and the cleaning device 104 to make full contact, and then controls the charging device 102 to charge the cleaning device 104, thereby avoiding the situation where an arc is generated when the charging device 102 transmits power to the cleaning device 104 due to insufficient contact between the charging device 102 and the cleaning device 104.

In some embodiments, as shown in FIG8 , the cleaning device 100 optionally further includes a second switch 122 . The second switch 122 is disposed within the charging device 102 and electrically connected to the power inlet 130 . When the second switch 122 is open, power cannot flow out of the charging device 102 through the power inlet 130 . When the second switch 122 is closed, power can flow out of the charging device 102 through the power inlet 130 . The second switch 122 is also communicatively connected to the second control device 120 , which can control the closing or opening of the second switch 122 . When the second detection device 118 detects the third voltage value, the second control device 120 controls the second switch 122 to close after a preset time interval, thereby enabling the charging device 102 to transmit power to the cleaning device 104 through the power inlet 130 , thereby enabling the charging device 102 to transmit power to the cleaning device 104 . That is, under normal circumstances, second switch 122 is in the open state. When second detection device 118 detects that charging device 102 is in contact with cleaning device 104, but charging device 102 has not yet transmitted power to cleaning device 104, second control device 120 waits for a preset time to allow sufficient contact between charging device 102 and cleaning device 104 before controlling second switch 122 to be closed, thereby enabling power transmission from charging device 102 to cleaning device 104. The preset waiting time of second control device 120 is the same as the preset time that cleaning device 104 moves toward charging device 102. By configuring second switch 122 to be closed only when second detection device 118 detects the third voltage value, the safety of charging device 102 is ensured.

In some embodiments, optionally, as shown in Figure 8, the cleaning device 100 also includes a metal pole piece 124, which can be located at the charging port 138 of the cleaning device 104 and/or the power transmission port 130 of the charging device 102. When the cleaning device 104 is in contact with the charging device 102, the charging port 138 of the cleaning device 104 and the power transmission port 130 of the charging device 102 are connected through the metal pole piece 124. By utilizing the conductivity of the metal pole piece 124, the electric energy transmitted from the power transmission port 130 of the charging device 102 can enter the charging port 138 of the cleaning device 104, thereby realizing the charging of the cleaning device 104 by the charging device 102.

In some embodiments, as shown in FIG8 , the cleaning device 100 optionally further includes a first infrared alignment circuit 126 and a second infrared alignment circuit 128 . The first infrared alignment circuit 126 is located on one side of the cleaning device 104, and the second infrared alignment circuit 128 is located on one side of the charging device 102. When the cleaning device 104 locates the charging device 102, it uses the first infrared alignment circuit 126 and the second infrared alignment circuit 128 to determine its location. Furthermore, when the cleaning device 104 and the charging device 102 come into contact, the first infrared alignment circuit 126 and the second infrared alignment circuit 128 align them, ensuring that the charging port 138 of the cleaning device 104 and the power port 130 of the charging device 102 are connected.

For example, the cleaning device 100 provided in the present application first places a charging control circuit, namely a first detection device 132, on the main control board of the cleaning device 104, namely the first control device 136, for detecting the external input power supply voltage. A control circuit, namely the second detection device 118, is placed on the charging device 102 for detecting the voltage state of the power transmission port 130; then, when the charging device 102 and the cleaning device 104 are not in contact, the power supply voltage value detected by the first detection device 132 in the cleaning device 104 is recorded as the fourth voltage value; when the charging device 102 and the cleaning device 104 are in contact, but the power switch of the charging device 102 is turned off, the power supply voltage value detected by the first detection device 132 in the cleaning device 104 is recorded as the second voltage value; when the charging device 102 and the cleaning device 104 are in contact, and the charging device 102 is in contact, the power supply voltage value detected by the first detection device 132 in the cleaning device 104 is recorded as the second voltage value. When the second switch 122 of the charging device 102 is open, the power supply voltage value detected by the first detection device 132 of the cleaning device 104 is recorded as the first voltage value. When the charging device 102 and the cleaning device 104 are not in contact and the second switch 122 of the charging device 102 is closed, the voltage value detected by the second detection device 118 of the charging device 102 is recorded as the fifth voltage value. When the charging device 102 and the cleaning device 104 are in contact and the second switch 122 of the charging device 102 is closed, the voltage value detected by the second detection device 118 of the charging device 102 is recorded as the third voltage value. When the second switch 122 of the charging device 102 and the first switch 116 of the cleaning device 104 are closed, the charging device 102 and the cleaning device 104 alternately detect the above voltages. When the metal electrode 124 of the cleaning device 104 and the charging device 102 are in contact, the cleaning device 104 moves toward the charging device 102 upon detecting the second voltage value and maintains this movement for a specific period of time, thereby ensuring full contact between the metal electrode 124. When the charging device 102 detects the third voltage value, it delays turning on the power supply for a specific time. The specific time that the cleaning device 104 continues to operate is the same as the specific time that the charging device 102 delays. When the cleaning device 104 detects the first voltage value after the charging device 102 turns on the power supply, it indicates that the cleaning device 104 has reached the designated location and can perform the target operation, i.e., charging, dust collection, cloth washing, drying, etc.

For example, the cleaning device 100 provided by the present application first places a charging control circuit, namely a first detection device 132, on the main control board of the cleaning device 104, namely the first control device 136, for detecting the external input power supply voltage. A control circuit, namely a second detection device 118, is placed on the charging device 102 for detecting the voltage state of the power transmission port 130; then, when the charging device 102 and the cleaning device 104 are not in contact, the power supply voltage value detected by the cleaning device 104 is recorded as the fourth voltage value; when the charging device 102 and the cleaning device 104 are in contact and the second switch 122 in the charging device 102 is disconnected, the power supply voltage value detected by the cleaning device 104 is recorded as the second voltage value; when the charging device 102 and the cleaning device 104 are in contact and the second switch 122 in the charging device 102 is in contact, the power supply voltage value detected by the cleaning device 104 is recorded as the second voltage value; When 122 is closed, the power supply voltage value detected by the cleaning device 104 is recorded as the first voltage value; when the charging device 102 and the cleaning device 104 are not in contact and the second switch 122 of the charging device 102 is disconnected, the voltage value detected by the control circuit in the charging device 102, i.e., the second detection device 118, is recorded as the fifth voltage value; when the charging device 102 and the cleaning device 104 are in contact and the second switch 122 of the charging device 102 is disconnected, the voltage value detected by the control circuit in the charging device 102, i.e., the second detection device 118, is recorded as the third voltage value. To begin charging, cleaning device 104 is first precisely aligned with charging device 102 using first infrared alignment circuit 126 and second infrared alignment circuit 128. With both second switches 122 of charging device 102 and 124 open, charging device 102 and cleaning device 104 alternately detect voltages. When cleaning device 104 and charging device 102 make contact via metal electrode 124, cleaning device 104 detects the second voltage value and moves toward charging device 102 for a specified period of time, ensuring full contact with metal electrode 124. Charging device 102 detects the third voltage value and then delays closing the second switch for a specified period of time, where the delay is the same as the delay of charging device 102. After charging device 102 closes its second switch, cleaning device 104 detects the first voltage value and, therefore, closes first switch 116 to begin charging. During charging, cleaning device 104 continuously monitors the external input power voltage and, if it is not at the first voltage value, opens first switch 116. Finally, the above steps are repeated until charging is complete, and the cleaning device 104 disconnects the first switch 116. Thus, the cleaning device 100 provided by this application solves the charging anomaly problem caused by sparks, blackening, and poor contact of the charging electrodes of the charging device 102 and cleaning device 104 on the market, thereby improving charging reliability. Furthermore, the mechanical microswitch is eliminated, reducing product costs.

In one embodiment of the present application, a control method for a cleaning device applied to any of the above embodiments is proposed. As shown in FIG3 , the control method for the cleaning device may specifically include the following steps 201 and 203:

Step 201: Detecting operating information of a cleaning device or a charging device;

Step 203: Control the cleaning device and/or the charging device to operate according to the operating information.

The technical solution of the control method for cleaning equipment provided in this application can be implemented by the control device of the cleaning equipment, and can also be determined according to actual use requirements, and is not specifically limited here. In order to more clearly describe the control method for cleaning equipment provided in this application, the following description is based on the implementation of the control method for cleaning equipment as the control device of the cleaning equipment.

Specifically, in the control method for cleaning equipment provided in this application, while the cleaning equipment is operating, operating information of the cleaning device or the charging device is detected, and then the cleaning device and/or the charging device are controlled to operate according to the operating information. For example, the cleaning device is controlled to perform cleaning operations, or the charging device is controlled to charge the cleaning device, etc. In this way, based on the operating information of the cleaning device or the charging device, the cleaning device and/or the charging device are controlled to operate, thereby ensuring the reliability of the operation of the cleaning device and/or the charging device, thereby ensuring the accuracy of the reliability of the operation of the cleaning equipment.

In one embodiment of the present application, optionally, as shown in FIG12 , the above step 203 may specifically include the following steps 202 to 208:

Step 202: adjusting the coil impedance of the first coil according to the operating information of the cleaning device;

Step 204: generating an induced current signal according to the coil impedance;

Step 206: Demodulate the induced current signal to obtain demodulated working information;

Step 208: Control the charging device to perform the work task on the cleaning device according to the work information, and/or control the second coil to send a power transmission signal to the cleaning device according to the work information, so as to provide charging power to the cleaning device through the power transmission signal for charging.

Specifically, in the control method for a cleaning device provided herein, during operation of the cleaning device, when the cleaning device of the cleaning device is close to the charging device so that the signals of the first coil and the second coil are connected, such as when the cleaning device completes its cleaning task and returns to the charging device, the control device of the cleaning device obtains the operating information of the cleaning device through the receiving control circuit on the cleaning device and encodes the obtained operating information. Specifically, the control device of the cleaning device adjusts the coil impedance of the first coil based on the operating information of the cleaning device, so as to modulate the operating information of the cleaning device and superimpose it on the impedance signal of the first coil. Based on this, the change in the coil impedance of the first coil causes the current in the second coil of the charging device to change. The second coil senses the coil impedance of the first coil and generates an induced current signal. Furthermore, the control device of the cleaning device reads the induced current signal through the transmitting control circuit on the charging device and demodulates the induced current signal to obtain the demodulation result, i.e., the operating information of the cleaning device. Furthermore, based on the demodulation result of the induced current signal, i.e., the operating information of the cleaning device, the control device of the cleaning device controls the charging device to operate. Specifically, based on the demodulated operating information of the cleaning device, the control device of the cleaning device controls the second coil to transmit a power transmission signal to the cleaning device, thereby providing charging power to the cleaning device via the power transmission signal. Furthermore, based on the demodulated result of the induced current signal, i.e., the operating information of the cleaning device, the control device of the cleaning device controls the charging device to perform a task on the cleaning device, such as controlling the charging device to collect dust from the cleaning device. Furthermore, the transmission control circuit can also adjust the amount of energy transmitted to the cleaning device via the power transmission signal to control the charging status of the cleaning device.

This allows for wireless charging of the cleaning device by the charging device during operation through both electrical-to-magnetic and magnetic-to-electrical conversions, improving the reliability and stability of charging. Furthermore, signal modulation and demodulation technology enables communication between the cleaning and charging devices, avoiding communication failures caused by signal obstruction, inaccurate alignment, poor network quality, and a poor communication environment, thereby improving the stability and reliability of communication between the charging and cleaning devices.

The aforementioned operating information may specifically include information related to the charging of the cleaning device, such as voltage, current, power, overvoltage, undervoltage, overcurrent, and over-temperature protection information. By controlling the second coil to transmit a power transmission signal to the cleaning device based on the operating information of the cleaning device, the charging status of the cleaning device can be controlled, such as the voltage, current, and power used to charge the cleaning device.

Furthermore, the aforementioned operating information may specifically include task instructions that the cleaning device requires the charging device to perform, such as dust collection instructions, cloth cleaning instructions, and drying instructions. By controlling the charging device to operate based on the operating information of the cleaning device, the charging device can be controlled to perform tasks such as dust collection, cloth cleaning, and drying for the cleaning device.

In some embodiments of the present application, optionally, the above step 202 may specifically include the following steps 202a and 202b:

Step 202a: detecting voltage and current information and work instruction information of the cleaning device, and determining work information of the cleaning device according to the voltage and current information and the work instruction information;

Step 202b: adjusting the resonant cavity parameters of the first coil on the cleaning device according to the working information to adjust the coil impedance of the first coil, and modulating the working information to be superimposed on the impedance signal of the first coil.

In this embodiment, in the process of the control device of the cleaning device adjusting the coil impedance of the first coil according to the working information of the cleaning device, the control device of the cleaning device detects the working instruction information and voltage and current information of the cleaning device through the receiving control chip in the receiving control circuit, and determines the working information of the cleaning device based on the detected working instruction information and voltage and current information. Furthermore, the control device of the cleaning device encodes the working information of the cleaning device through the modulation circuit in the receiving control circuit. Specifically, the modulation circuit adjusts the resonant cavity parameters of the first coil based on the working information of the cleaning device to adjust the coil impedance of the first coil, and modulates the working information of the cleaning device and superimposes it on the impedance signal of the first coil. In this way, the communication interaction between the cleaning device and the charging device is realized based on the signal modulation and demodulation technology, avoiding the problem of communication failure caused by signal blocking, inaccurate alignment, poor network quality and poor communication environment, and improving the stability and reliability of the communication interaction between the charging device and the cleaning device.

It's understandable that adjusting the resonant cavity parameters of the first coil can change the impedance of the first coil, which in turn changes the current flowing through the second coil. Thus, the transmission control circuit in the charging device can determine the impedance change of the first coil by measuring and analyzing the current flowing through the second coil, thereby demodulating and obtaining operating information about the cleaning device.

In actual application, the above-mentioned work instruction information is specifically a task instruction that the cleaning device requires the charging device to perform, such as a dust collection instruction, a rag cleaning instruction, and a drying instruction, etc., which is not specifically limited here.

Furthermore, the cleaning device's control device can also detect power information, overvoltage information, undervoltage information, overcurrent information, and over-temperature protection information from the cleaning device via the receiving control chip, and modulate and superimpose this information on the impedance signal of the first coil. In this way, the cleaning device can limit parameters such as the energy level, voltage level, current level, and power level of the charging device, while also implementing functions such as overvoltage protection, overcurrent protection, and over-temperature protection for the cleaning device.

In some embodiments of the present application, optionally, the above step 204 may specifically include the following steps 204a and 204b, and the above step 206 may specifically include the following steps 206a and 206b:

Step 204a: determining impedance change information of the first coil according to the coil impedance;

Step 206a: Demodulate the induced current signal to determine impedance change information of the first coil;

Step 206b: determining the operating information of the cleaning device according to the impedance change information;

The impedance change information includes the impedance change value and impedance change frequency of the first coil.

In this embodiment, in the process of the control device of the cleaning equipment generating an induced current signal according to the coil impedance, the control device of the cleaning equipment determines the impedance change information of the first coil according to the coil impedance, and then generates an induced current signal according to the impedance change information. Wherein, the above-mentioned impedance change information includes the impedance change value and impedance change frequency of the first coil. On this basis, in the process of the control device of the cleaning equipment demodulating the induced current signal to obtain the demodulated working information, the control device of the cleaning equipment demodulates the induced current signal, determines the impedance change information of the first coil, and then determines the working information of the cleaning device according to the impedance change information. In this way, the communication interaction between the cleaning device and the charging device is realized based on the signal modulation and demodulation technology, avoiding the problem of communication failure caused by signal blocking, inaccurate alignment, poor network quality and poor communication environment, and improving the stability and reliability of the communication interaction between the charging device and the cleaning device.

In some embodiments of the present application, the work information may optionally include work instruction information of the cleaning device. Based on this, the step of controlling the charging device to perform the work task on the cleaning device according to the work information may specifically include the following step 210:

Step 210: Control the working components in the charging device to perform the working task on the cleaning device according to the working instruction information;

The work tasks include at least one of the following: dust collection task, cleaning task and drying task.

In this embodiment, the demodulation result of the induced current signal, i.e., the working information of the cleaning device, may include the working instruction information of the cleaning device. The working instruction information is specifically the task instruction that the cleaning device requires the charging device to perform, such as dust collection instruction, rag cleaning instruction, and drying instruction, etc., which is not specifically limited here.

On this basis, as the cleaning device's control device controls the charging device's operation based on the cleaning device's operating information, the cleaning device's control device controls the working components of the charging device to operate according to the aforementioned operating instruction information, thereby performing dust collection, cleaning, and drying tasks on the cleaning device. In this way, signal modulation and demodulation technology enables communication between the cleaning device and the charging device, thereby controlling the charging device's execution of the cleaning device's operating tasks. This improves the stability and reliability of communication between the charging and cleaning devices, and enhances the timeliness and accuracy with which the charging device executes its operating tasks.

In some embodiments of the present application, the operating information may optionally include voltage and current information of the cleaning device. Based on this information, the step of controlling the second coil to send a power transmission signal to the cleaning device according to the operating information may specifically include the following step 212:

Step 212: Adjust the operating frequency of the charging device according to the voltage and current information to adjust the current on the second coil in the charging device, and control the second coil to send a power transmission signal carrying charging power to the cleaning device.

In this embodiment, the demodulated result of the induced current signal, i.e., the operating information of the cleaning device, may also include voltage and current information of the cleaning device. Based on this information, when controlling the second coil to transmit a power transmission signal to the cleaning device based on the operating information of the cleaning device, the control device of the cleaning device controls the transmitting control chip to perform a full-bridge inverter output based on the demodulated voltage and current information. This adjusts the operating frequency of the charging device to adjust the current in the second coil, controls the second coil to transmit a power transmission signal carrying charging power to the cleaning device, and controls the amount of energy transferred to the cleaning device via the power transmission signal, thereby controlling the charging of the cleaning device. Based on this, the first coil can sense the power transmission signal and generate a charging power signal, which is then used to charge the cleaning device. In this way, signal modulation and demodulation technology enables communication between the cleaning device and the charging device, thereby controlling the charging parameters of the cleaning device, improving the stability and reliability of communication between the charging device and the cleaning device, and improving the reliability of charging the cleaning device.

In actual application, the impedance signal of the first coil can also carry power information, overvoltage information, undervoltage information, overcurrent information and over-temperature protection information of the cleaning device. The transmitting control core can adjust the operating frequency of the charging device according to the above information, thereby controlling the energy, voltage, current and power parameters of the charging device for charging the sweeping, thereby realizing the overvoltage protection, overcurrent protection and over-temperature protection functions of the cleaning device.

In some embodiments of the present application, optionally, as shown in FIG4 , step 203 includes the following steps 302 and 304:

Step 302: Acquire a voltage value detected by a first detection device in the cleaning device;

Step 304: When the voltage value detected by the first detection device is the first voltage value, controlling the cleaning device to perform the target operation;

The first voltage value is a voltage value of a charging port of the cleaning device when the charging device transmits power to the cleaning device.

In this embodiment, controlling the cleaning device and/or charging device to operate based on the operating information includes: first obtaining a voltage value detected by a first detection device within the cleaning device. Since the first detection device detects the voltage value at the charging port of the cleaning device, obtaining the voltage value detected by the first detection device can determine the operating status between the cleaning device and the charging device. When the voltage value detected by the first detection device is a first voltage value, the cleaning device is controlled to perform a target operation, wherein the first voltage value is the voltage value at the charging port of the cleaning device when the charging device is transmitting power to the cleaning device. In other words, after obtaining the voltage value detected by the first detection device, the voltage value is analyzed. When the analysis shows that the voltage value represents contact between the cleaning device and the charging device, and that the charging device is transmitting power to the cleaning device, indicating that the cleaning device has reached the designated position, the cleaning device is controlled to perform the target operation, wherein the target operation can be an action such as charging, dust collection, rag washing, and drying. The present application obtains the voltage value detected by the first detection device. When the detected voltage value is the voltage value of the charging port when the charging device transmits power to the cleaning device, it indicates that the cleaning device has reached the specified position. Therefore, the cleaning device is controlled to perform the target work, thereby solving the problem in the related art that the cleaning device cannot sense that it has reached the specified position and cannot work normally due to damage and failure of the mechanical micro switch.

In some embodiments, optionally, as shown in FIG5 , the above step 203 may further include the following step 306:

Step 306: When the voltage value detected by the first detection device is a second voltage value, control the cleaning device to move toward the charging device for a predetermined time.

The second voltage value is a voltage value of the charging port when the cleaning device is in contact with the charging device and the charging device is not transmitting power to the cleaning device.

In this embodiment, controlling the cleaning device and/or charging device to operate based on the operating information further includes: when the voltage value detected by the first detection device is a second voltage value, which is the voltage value of the charging port when the cleaning device and the charging device are in contact and the charging device is not transmitting power to the cleaning device, controlling the cleaning device to move toward the charging device for a preset time period to ensure that the cleaning device and the charging device are in full contact. In other words, when the voltage value detected by the first detection device determines that the current operating state between the cleaning device and the charging device is contact between the cleaning device and the charging device, but the charging device is not transmitting power to the cleaning device, controlling the cleaning device to move toward the charging device for a preset time period to ensure that the charging device and the cleaning device are in full contact before the charging device transmits power to the cleaning device, thereby avoiding arcing when the charging device transmits power to the cleaning device due to insufficient contact between the charging device and the cleaning device, and avoiding arcing when the charging device and the cleaning device are in contact in the charging state. For example, the preset time period during which the cleaning device moves toward the charging device and remains in contact can be the same as the preset time period during which the charging device waits before transmitting power to the cleaning device.

In some embodiments, optionally, as shown in FIG9 , the step of controlling the cleaning device to perform the target task includes:

Step 308: Determine target work;

Step 310 : When the target operation is charging, control a first switch in the cleaning device to be in a closed state, so that the cleaning device receives electric energy delivered by the charging device.

In this embodiment, the step of controlling the cleaning device to perform the target work includes: first determining the specific content of the target work. For example, the specific content of the target work can be charging, dust collection, rag washing, drying, etc. When the target work is charging, the first switch in the cleaning device is controlled to be in a closed state, so that the cleaning device can receive the electrical energy transmitted by the charging device. Since the first switch is connected to the battery, when the target work is charging and the first detection device detects the first voltage value, the first switch is controlled to be in a closed state, thereby realizing charging of the battery. And since the first switch is controlled to be closed only when charging, the safety of the battery of the cleaning device can also be guaranteed when the cleaning device is performing other work.

In some embodiments, optionally, the control method of the cleaning device further includes: controlling a first switch in the cleaning device to be in a closed state based on the voltage value detected by the first detection device being a first voltage value.

In this embodiment, the control method for a cleaning device further includes: when a first detection device detects a first voltage value, where the first voltage value is the voltage value of the charging port when the charging device is transmitting power to the cleaning device, i.e., when the operating state between the charging device and the cleaning device is that the charging device is transmitting power to the cleaning device, controlling a first switch within the cleaning device to be closed. The first switch within the cleaning device connects the charging port of the cleaning device to the battery, respectively. By controlling the first switch to be closed, the battery within the cleaning device receives the power transmitted by the charging device, thereby completing the charging process of the cleaning device. Simultaneously, during the charging process, the voltage value detected by the first detection device is monitored in real time. When the voltage value detected by the first detection device is not the first voltage value, indicating that the charging device has stopped transmitting power to the cleaning device, or that the voltage transmitted by the charging device to the cleaning device exceeds a limit, the first switch is controlled to be opened, thereby stopping the battery from receiving further power from the charging device. By controlling the opening and closing of the first switch, the safety of the battery is protected.

In some embodiments, optionally, as shown in FIG10 , the control method of the cleaning device further includes:

Step 312: Obtain the working status of the battery in the cleaning device;

Step 314: Based on the battery's operating status being charging completed, control the first switch to be in an off state.

In this embodiment, the control method for a cleaning device further includes: obtaining the operating status of a battery within the cleaning device in real time, where the battery operating status can be selected as uncharged, charging, or fully charged. When the battery operating status indicates fully charged, indicating that the battery no longer requires further power from the charging device, the first switch is controlled to open, thereby terminating the charging operation of the cleaning device. By controlling the first switch to open after battery charging is complete, the battery is protected.

In some embodiments, optionally, as shown in FIG11 , the above step 203 may specifically include the following steps 402 and 404:

Step 402: Obtaining a voltage value detected by a second detection device in the charging device;

Step 404: When the voltage value detected by the second detection device is a third voltage value, controlling the charging device to transmit electric energy to the cleaning device;

The third voltage value is a voltage value of the power transmission port of the charging device when the cleaning device is in contact with the charging device and the charging device is not transmitting power to the cleaning device.

In this embodiment, controlling the operation of the cleaning device and/or the charging device based on the operation information includes: obtaining a voltage value detected by a second detection device within the charging device. Since the second detection device detects the voltage value at the power transmission port of the charging device, the voltage value detected by the second detection device can be used to determine the operating status between the charging device and the cleaning device based on the voltage value. When the voltage value detected by the second detection device is a third voltage value, which is the voltage value at the power transmission port of the charging device when the cleaning device and the charging device are in contact and the charging device is not transmitting power to the cleaning device, the charging device is controlled to transmit power to the cleaning device. In other words, after obtaining the voltage value detected by the second detection device, when it is determined based on the obtained voltage value that the current operating status between the charging device and the cleaning device is contact between the charging device and the cleaning device but the charging device is not transmitting power to the cleaning device, the charging device is controlled to transmit power to the cleaning device, thereby achieving the technical effect of transmitting electrical energy between the cleaning device and the charging device.

In some embodiments, optionally, as shown in FIG6 , step 404 may specifically include:

Step 404a: When the voltage value detected by the second detection device is a third voltage value, control the charging device to transmit electric energy to the cleaning device after a preset delay.

In this embodiment, when the voltage value detected by the second detection device is a third voltage value, the charging device is controlled to delay power transmission to the cleaning device for a preset time. The third voltage value is the voltage value at the power transmission port of the charging device when the charging device and the cleaning device are in contact but the charging device is not transmitting power to the cleaning device. In other words, when the second detection device detects the third voltage value, it indicates that the charging device and the cleaning device are in contact with each other, but the charging device has not yet transmitted power to the cleaning device. The device then waits for a preset time to allow sufficient contact between the charging device and the cleaning device, and then controls the charging device to transmit power to the cleaning device. This application ensures sufficient contact between the charging device and the cleaning device by controlling the charging device to transmit power to the cleaning device after a preset time when the operating state between the cleaning device and the charging device is that the cleaning device and the charging device are in contact but the charging device is not transmitting power to the cleaning device. This avoids arcing caused by insufficient contact between the charging device and the cleaning device when the charging device transmits power to the cleaning device.

In some embodiments, optionally, as shown in FIG13 , the step of controlling the charging device to transmit electric energy to the cleaning device after a preset delay time includes:

Step 406: Determine the first time when the voltage value detected by the second detection device is the third voltage value;

Step 408: Determine a second time based on the first time and the preset time;

Step 410: When the time reaches a second time, control the second switch in the charging device to be in a closed state, so that the charging device transmits power to the cleaning device.

In this embodiment, the step of controlling the charging device to transmit electrical energy to the cleaning device includes: first, determining the time at which the second detection device detects the third voltage value as a first time; then, determining a second time based on the first time and a preset time, i.e., delaying the first time by the preset time to obtain the second time; and, when the second time is reached, controlling a second switch within the charging device to be closed, thereby enabling the charging device to transmit electrical energy to the cleaning device. In other words, after the second detection device detects the third voltage value, it is necessary to wait for a preset time to allow sufficient contact between the charging device and the cleaning device to prevent arcing between the two devices. After the preset time, controlling the second switch to be closed, allowing electrical energy to flow out of the power transmission port through the second switch to charge the cleaning device. By closing the second switch only when the charging device is transmitting electrical energy to the cleaning device, the safe use of the charging device is also ensured.

In one embodiment of the present application, a control device for a cleaning device in any of the above embodiments is also provided. As shown in FIG14 , FIG14 shows a block diagram of a control device 500 for a cleaning device in an embodiment of the present application.

The control device 500 for a cleaning device provided in an embodiment of the present application includes a modulation unit 502, a demodulation unit 504, a control unit 506, and a processing unit 508. During operation of the cleaning device, when the cleaning device of the cleaning device is close to the charging device so that the signals of the first coil and the second coil are connected, such as when the cleaning device completes the cleaning task and returns to the charging device, the modulation unit 502 obtains the operating information of the cleaning device through the receiving control circuit on the cleaning device and encodes the obtained operating information. Specifically, the modulation unit 502 adjusts the coil impedance of the first coil according to the operating information of the cleaning device to modulate the operating information of the cleaning device and superimpose it on the impedance signal of the first coil. On this basis, the change in the coil impedance of the first coil will cause the current in the second coil in the charging device to change. The processing unit 508 senses the coil impedance of the first coil through the second coil and generates an induced current signal. Furthermore, the demodulation unit 504 reads the induced current signal through the transmitting control circuit on the charging device and demodulates the induced current signal to obtain the demodulation result, which is the operating information of the cleaning device. Furthermore, the control unit 506 controls the charging device to operate based on the demodulation result of the induced current signal, which is the operating information of the cleaning device. Specifically, based on the demodulated operating information of the cleaning device, the control unit 506 controls the second coil to transmit a power transmission signal to the cleaning device, thereby providing charging power to the cleaning device via the power transmission signal. Furthermore, based on the demodulated result of the induced current signal, i.e., the operating information of the cleaning device, the control unit 506 controls the charging device to perform a task on the cleaning device, such as controlling the charging device to collect dust from the cleaning device. Furthermore, based on the demodulated operating information of the cleaning device, the control unit 506 adjusts the amount of energy transmitted to the cleaning device via the power transmission signal to control the charging of the cleaning device.

This allows for wireless charging of the cleaning device by the charging device during operation through both electrical-to-magnetic and magnetic-to-electrical conversions, improving the reliability and stability of charging. Furthermore, signal modulation and demodulation technology enables communication between the cleaning and charging devices, avoiding communication failures caused by signal obstruction, inaccurate alignment, poor network quality, and a poor communication environment, thereby improving the stability and reliability of communication between the charging and cleaning devices.
