It should be noted that, unless in conflict, the embodiments and technical features in the embodiments in this application may be combined with each other, and the detailed descriptions in specific embodiments should be understood as an explanation of the intent of this application and should not be considered as an inappropriate limitation to this application.

An embodiment of the present application provides a cleaning device, which can be used to clean a cleaning medium such as a floor, glass, etc., and when the cleaning device is operated, the cleaning device is placed on the surface of the cleaning medium.

The cleaning device may be a floor cleaning robot, a window cleaning robot, or may also be a device of this type, without limitation. In the embodiment of the present application, it is described by way of example that the cleaning device is a floor cleaning robot.

Referring to FIG. 1, the cleaning device includes a pumping device (30), a cleaning area (10a), and an operating mechanism (20); wherein the pumping device (30) includes a receiving portion (31) and a transitional connection mechanism (33), and the receiving portion (31) is provided with a receiving space (310) and a drainage port (31b) communicating with the receiving space (310), and the drainage port (31b) is communicated with the cleaning area (10a), for example, through a drainage pipe (37); the transitional connection mechanism (33) is operatively connected with the operating mechanism (20), and the transitional connection mechanism (33) can pump water in the receiving space (310) to the cleaning area (10a) by driving the operating mechanism (20).

The cleaning device of the embodiment of the present application uses a ready-made operating mechanism (20) as a power source, drives a pumping operation through a transitional connection mechanism (33), and the amount of additional water required for the cleaning area (10a) is determined by the operation of the operating mechanism (20) and the volume of water stored in the receiving space (310), and there is no need to perform control through a control circuit. Therefore, compared to a method of adding water through a water pump in the prior art, the structural reliability and practicality of the pumping device (30) of the embodiment of the present application are higher, the production and manufacturing cost is lower, and it is advantageous in promoting use.

What should be explained is that the above-mentioned operating mechanism (20) means an external operating mechanism for implementing the cleaning function of the cleaning device, such as a walking wheel (20') or a roll brush. The walking wheel (20') implements the movement function of the cleaning device, and the cleaning device must implement a continuous cleaning operation through the movement of the walking wheel (20'); and the roll brush implements the function of brushing the cleaning medium of the cleaning device.

The cleaning area (10a) refers to a part that comes into contact with the cleaning component (40), and the cleaning component (40) may be a mop, a sponge, or the like. For example, referring to FIG. 1, the cleaning area (10a) may be the lower part of the bracket (12) for installing the cleaning component (40), and before the cleaning device operates normally, the cleaning component (40) is installed at the lower part of the bracket (12), water in the water storage space (310) is pumped to the cleaning area (10a), and the water in the cleaning area (10a) is absorbed by the cleaning component (40), and during the next process of the cleaning device moving, the cleaning component (40) performs wiping cleaning on the cleaning medium.

It should be explained that the over-connection mechanism (33) can pump water within the receiving space (310) to the cleaning area (10a) using a different structure; and can pump water within the receiving space (310) to the cleaning area (10a) without using a different structure, for example, the over-connection mechanism (33) continuously and unidirectionally pumps air or other gas into the receiving space (310) by driving the operating mechanism (20), and the water within the receiving space (310) is pumped into the cleaning area (10a) under the action of air pressure.

In an embodiment of the present application, the over-connection mechanism (33) uses a different structure to pump water into the water cleaning area (10a) within the receiving space (310), specifically, the pumping device (30) includes a pumping unit (32), the pumping unit (32) is movably installed within the receiving space, the pumping unit (32) and the receiving unit (31) are surrounded together to form a water storage cavity (311), and the pumping unit (32) can pump water within the water storage cavity (311) to the cleaning area (10a), that is, the over-connection mechanism (33) uses the pumping unit (32) to pump water within the receiving space (310) to the cleaning area (10a). The embodiment of the present application drives the pumping unit (32) to perform a draining operation by transmitting power to the pumping unit (32) through the over-connection mechanism (33), thereby directly applying a greater pressure to the water in the water storage cavity (311), and is convenient for pumping the water in the water storage cavity (311) to the cleaning area (10a).

The specific structure of the receiving portion (31) is not limited, and as long as it can receive a certain volume of water, it is not limited here. In some embodiments, the cleaning device includes a tank (11), and a certain volume of water or a cleaning agent is pre-stored in the tank (11), and for the convenience of explanation, the embodiments of the present application are described using water as an example. The receiving portion (31) may be at least a portion of the structure of the tank (11), for example, a space in the tank (11) is isolated to form a receiving space of the receiving portion (31), and water pre-stored in the tank (11) enters the water storage cavity (311) through a through-hole of a certain diameter; for another example, the tank (11) itself is the receiving portion (31), and the space in the tank (11) is the water storage cavity (311).

For another example, referring to FIG. 1, in the embodiment of the present application, the receiving portion (31) is located on the outside of the water tank (11), and the receiving portion (31) is formed with an inlet (31a) that communicates with a water storage cavity (311), and the inlet (31a) is communicated with the water tank (11). It should be understood that the receiving portion (31) can be fastened and connected to the water tank (11), and can also be installed to be spaced apart from the receiving portion (31), but is not limited thereto. In the embodiment of the present application, by installing the receiving portion (31) on the outside of the water tank (11), the water tank (11) can have a relatively large volume within the limited space of the cleaning device, thereby improving the water storage capacity, and at the same time, the relative positions between the water tank (11), the cleaning area (10a) and the receiving portion (31) can be flexibly arranged, and the water tank (11), the cleaning area (10a) and the receiving portion (31) only need to be communicated through a corresponding pipeline, so that the structural design of the cleaning device is more flexible, and the structural layout of the cleaning device is more reasonable and compact.

In the embodiment of the present application, the operating mechanism (20) is a walking wheel (20'), and the transitional coupling mechanism (33) is connected to the walking wheel (20'), the rotation process of the walking wheel (20') is related to the marching distance of the cleaning device, and thus, the movement fluctuation range of the pumping unit (32) is related to the marching distance of the cleaning device. Specifically, when the cleaning device does not march, the walking wheel (20') stops, the transitional coupling mechanism (33) remains stopped, and the pumping unit (32) will not move either, at which time the cleaning component (40) will not perform the wiping cleaning operation, and the pumping device (30) will not drain into the cleaning area (10a); When the cleaning device marches a short distance, the rotational fluctuation range of the walking wheel (20') is relatively small, and the movement stroke of the pumping unit (32) is also relatively small, so the amount of water pumped by the pumping device (30) into the cleaning area (10a) is also relatively small, and when the cleaning device marches a short distance, the amount of additional water required by the cleaning component (40) is also relatively small, so that the amount of water pumped by the pumping device (30) into the cleaning component (40) and the amount of additional water required by the cleaning component (40) can be relatively well matched; similarly, when the distance of the cleaning device marches is relatively large, the amount of water pumped by the pumping device (30) into the cleaning area (10a) is relatively large, and the amount of additional water required by the cleaning component (40) is also relatively large.

In one embodiment, the over-connection mechanism (33) is connected to one side of the axial direction of the walking wheel (20'). This is convenient for connecting the over-connection mechanism (33) and the walking wheel (20'). Furthermore, the over-connection mechanism (33) is connected to the inner side of the axial direction of the walking wheel (20'), which means that the over-connection mechanism (33) will not be exposed to the outside of the cleaning device, and during the operation of the cleaning device, the over-connection mechanism (33) will not interfere with other external items; in addition, the structural arrangement of the pumping device (30) is more reasonable, and it is convenient for compactness.

The structural forms of the receiving portion (31) and the pumping portion (32) are various, for example, in one embodiment, the receiving portion (31) is cylindrical and, correspondingly, the pumping portion (32) is a piston (32'); in another embodiment, the receiving portion (31) is volute-shaped and the pumping portion (32) is a rotor.

The relative positions of the water tank (11), the operating mechanism (20), the transition connection mechanism (33) and the cleaning area (10a) can be appropriately changed according to demand.

Below, specific embodiments of the present application are described by combining the drawings.

Example 1

Referring to FIGS. 1 and 2, in the present embodiment, the receiving portion (31) is located outside the water tank (11). The receiving portion (31) is cylindrical, one end of the receiving portion (31) is a closed end, the other end is an open end, the pumping portion (32) is a piston (32'), the piston (32') performs a linear reciprocating motion within the receiving portion (31), and the piston (32') alternately introduces water within the water tank (11) into the water storage cavity (311) and pumps water within the water storage cavity (311) to the cleaning area (10a). In other words, at the same time, only one of the operations of introducing water in the water tank (11) into the water storage cavity (311) and the operations of pumping water in the water storage cavity (311) into the cleaning area (10a) can be selected, and specifically, when the over-connection mechanism (33) drives the piston (32') to slide in the first direction to the left as shown in FIG. 1, the volume of the water storage cavity (311) expands, so that a negative pressure is formed in the water storage cavity (311), and the water in the water tank (11) is sucked into the water storage cavity (311) under the action of the negative pressure, and in the process, the water channel between the drain (31b) and the cleaning area (10a) is blocked. When the over-connection mechanism (33) drives the piston (32') to slide in the second direction to the right as shown in FIG. 1, the piston (32') exerts a force on the water in the water storage cavity (311), so that the water in the water storage cavity (311) builds up a certain water pressure, and the water pressure can pump the water to the cleaning area (10a), and in the process, the water path between the water inlet (31a) and the water tank (11) is blocked.

In order to facilitate the opening and closing control of the water channel between the inlet (31a) and the water tank (11), and to facilitate the opening and closing control of the water channel between the drain (31b) and the cleaning area (10a), a valve is installed in the corresponding water channel so that it can be opened or closed at the appropriate time. The structural type of the valve is not limited, and may be an electric control valve, a hydraulic control valve, or the like.

In this embodiment, the pumping device (30) includes a first check valve (34), and the first check valve (34) belongs to one type of hydraulic control valve, and can perform open and close control without requiring electronic control. The first check valve (34) is installed in a water channel between the inlet (31a) and the water tank (11). It can be understood that the first check valve (34) can allow water to flow from one side of the water tank (11) to one side of the inlet (31a), that is, the inlet end of the first check valve (34) is communicated with the water tank (11), and the outlet end of the first check valve (34) is communicated with the inlet (31a). The structure of the first check valve (34) is simple, does not require electric control, and can automatically implement open and close according to water pressure. For example, when the negative pressure inside the water storage cavity (311) is greater than the opening pressure of the first check valve (34), the first check valve (34) is opened, and water inside the water tank (11) enters the water storage cavity (311) through the first check valve (34) under the negative pressure of the water storage cavity (311); when the water inside the water storage cavity (311) builds up pressure, the water pressure acts on the first check valve (34) in the opposite direction, and the first check valve (34) is closed, and since the water pressure inside the water tank (11) is insufficient to open the first check valve (34), the first check valve (34) can be stably, reliably, and automatically shut off.

The pumping device (30) includes a second check valve (35), and the second check valve (35) is installed in the water channel between the drain (31b) and the cleaning area (10a). The operating principle and operation process of the second check valve (35) are similar to those of the first check valve (34), and are not described here again.

It can be understood that a group of valves can be selected, for example, in some embodiments, the second check valve (35) can be installed in the water passage between the drain (31b) and the cleaning area (10a), and an electric control valve or another type of hydraulic control valve can be installed in the water passage between the inlet (31a) and the water tank (11); in another embodiment, the first check valve (34) can be installed in the water passage between the inlet (31a) and the water tank (11), and an electric control valve or another type of electric control valve can be installed in the water passage between the drain (31b) and the cleaning area (10a).

Taking the drain port (31b) as an example, if the drain port (31b) is located on the side wall of the receiving portion (31), i.e., located at the non-closed end, when the piston (32’) moves toward the closed end, the water in the water storage cavity (311) cannot be discharged if the piston (32’) moves until the circumference of the piston (32’) blocks the drain port (31b), and if the piston (32’) continues to move toward the closed end by the driving of the over-connection mechanism (33), the water pressure in the water storage cavity (311) is applied and the pressure continuously increases, which may damage the piston (32’), the receiving portion (31), or the valve. Therefore, when designing a product, the range of motion of the piston (32’) should not cover the position of the drain (31b), but this can increase the size of the receiving portion (31) in the direction in which the piston (32’) moves under the same conditions.

To this end, in the embodiment of the present application, the inlet (31a) and the drain (31b) are installed at the ends on one side of the sliding direction of the piston (32') in the receiving portion (31), i.e., located at the closed end of the receiving portion (31), so that the piston (32') can continue to move to the position where the closed end comes into contact, and the receiving portion (31) can have a more compact structure under the same conditions, and can prevent the water storage cavity (311) from being pressurized.

In the embodiment of the present application, referring to FIG. 2, the transition connecting mechanism (33) is a crank (33’). Specifically, one end of the crank (33') is connected to one side of the water storage cavity (311) of the piston (32'), and the other end of the crank (33') is rotatably connected to the actuation mechanism (20), the actuation mechanism (20) has a first rotation axis (see point O1 in FIG. 1), that is, the actuation mechanism (20) rotates around the first rotation axis, the second end of the crank (33') has a second rotation axis (see point O2 in FIG. 1), the first rotation axis and the second rotation axis are installed eccentrically, that is, in the process of the crank (33') rotating along the actuation mechanism (20), it orbits around the first rotation axis and also rotates around the second rotation axis, and the actuation mechanism (20) drives the piston (32') to make a linear reciprocating motion through the crank (33'), in other words, the actuation mechanism (20), the crank (33') and The piston (32’) forms a crank (33’) sliding block structure, and the crank (33’) can convert the rotational motion of the operating mechanism (20) into the linear sliding motion of the piston (32’).

In this embodiment, the actuating mechanism (20) is a walking wheel (20'). It should be understood that the actuating mechanism (20) may also be a roll brush or another type of actuating mechanism (20).

Second Example

Referring to FIG. 3, what is different from the first embodiment is that in this embodiment, the over-connection mechanism (33) includes a cam (331), a slider (332), and an elastic member (333), one end of the slider (332) is rotatably connected to the piston (32') in a hinge-like manner, the elastic member (333) applies a force toward the cam (331) to the slider (332) to press the other end of the slider (332) against the circumference of the cam (331), the actuation mechanism (20) has a first rotational axis, and the cam (331) is coaxially connected with the actuation mechanism (20), that is, when the actuation mechanism (20) rotates about the first rotational axis, the cam (331) also rotates about the first rotational axis.

Since the circumferential shape of the cam (331) is non-circular, when the cam (331) rotates around the first rotation axis, the slider (332) causes a linear reciprocating movement under the joint action of the elastic component (333) and the cam (331), thereby causing the piston (32’) to perform a linear reciprocating movement.

Specifically, in the embodiment of the present application, the elastic component (333) is a spring, the spring is sleeved on the slider (332), and the slider (332) implements a guiding action for the expansion and contraction movement of the spring, thereby improving the reliability of the spring. One end of the spring is in contact with one side facing the water storage cavity (311) of the piston (32'). Furthermore, with continued reference to FIG. 3, a flange structure (3321) is formed in the circumferential direction of the slider (332), and the other end of the spring is in contact with one side facing the receiving portion (31) of the flange structure (3321), that is, the spring is clamped between the flange structure (3321) and the piston (32').

What is different from the first embodiment is that in this embodiment, the receiving portion (31) is in the form of a volute, the pumping portion (32) is a rotor, the rotor rotates within the receiving portion (31), and the rotor synchronously introduces water within the water tank (11) into the water storage cavity (311) and pumps water within the water storage cavity (311) to the cleaning area (10a). In other words, the rotor simultaneously performs the work process of introducing water within the water tank (11) into the water storage cavity (311) and the work process of pumping water within the water storage cavity (311) to the cleaning area (10a), and the two work processes are performed synchronously.

In the above embodiment, the water inlet (31a) and the drain outlet (31b) are respectively located on the relative opposite sides of the rotor, the rotor divides the receiving space (310) into a first cavity and a second cavity, and the first cavity and the second cavity together form a water storage cavity (311), that is, the water inlet (31a) is communicated with the first cavity, and the drain outlet (31b) is communicated with the second cavity, and when the rotor rotates, the rotor squeezes the water in the first cavity into the second cavity, the first cavity generates a negative pressure, and the water in the water tank (11) is sucked into the first cavity under the negative pressure, and the water in the second cavity builds up a certain water pressure, and the water pressure pumps the water in the second cavity to the cleaning area (10a).

The operating mechanism (20) has a first rotation axis, the rotor has a third rotation axis, the first rotation axis and the third rotation axis are parallel and eccentrically installed, and the over-coupling mechanism (33) can transmit the torque of the operating mechanism (20) to the rotor.
