Description

Background inhibition bathroom inductor and induction self-starting equipment

Technical Field

The invention relates to the technical field of bathroom equipment, in particular to a background inhibition bathroom sensor and induction self-starting equipment with the background inhibition bathroom sensor.

Background

In modern bathroom facilities, the introduction of automated sensing technology greatly improves the convenience and sanitation standards of use. In particular induction type faucets, toilets, urinals, etc. products, which are often equipped with infrared reflective sensors for sensing the proximity of the user and activating the corresponding functions, such as turning on the water flow, flushing, etc. within the effective range. The operating principle of the infrared reflection sensor is based on the emission and the receiving of infrared rays, and whether an object is close or not is judged by detecting the reflection intensity of the infrared rays. However, this technique has significant limitations and disadvantages, especially in a bathroom environment.

Limitations of the prior art are as follows:

1. The color and the material of the object are obviously influenced by the color and the material of the surface of the object. For example, light colored objects or high reflectivity surfaces (e.g., mirrors, white ceramic sinks) may result in an increase in reflected signals, which may trigger the sensor when the object has not completely entered the active sensing area, whereas dark colored objects or light absorbing materials (e.g., some clothing, leather shoes) may attenuate the reflected signals, which may not respond properly even if the object has been in proximity.

2. The influence of the field illumination condition is that the change of the external illumination condition can also interfere the normal operation of the infrared reflection sensor. In strong light conditions, the background light may enhance or interfere with the reflected signal, resulting in erroneous decisions, while in low light conditions, the sensitivity of the sensor may decrease, affecting its normal sensing.

3. The problems of cost and power consumption are that some improved sensors, such as PSD (Position Sensitive Detector) induction devices, TOF (Time of Flight) induction devices, microwave induction devices and ultrasonic induction devices, overcome the problems to a certain extent, but the improved sensors respectively bring new problems of high cost, high power consumption, complex installation, poor waterproof performance or excessively wide induction area, easy false triggering and the like, and the problems are particularly remarkable in bathroom occasions.

Wherein:

Although the PSD sensing device can provide higher position accuracy, the PSD sensing device has the defects of high cost, strict installation requirement and difficult popularization due to a plurality of components.

The TOF sensing device measures distance by utilizing light flight time, but has high cost and larger power consumption, and is not suitable for bathroom scenes which continuously work for a long time.

The microwave induction device is easy to generate false triggering during multi-station simultaneous induction due to the wide-angle emission characteristic of 180 degrees, and has large using power, thereby being unfavorable for energy conservation and environmental protection.

Although the ultrasonic sensing device has lower cost, the ultrasonic sensing device needs to be perforated during installation, which not only damages the beauty of bathroom equipment, but also has poor waterproof performance and is not suitable for being in a humid environment for a long time.

In summary, the prior art has limitations in adaptability, cost, power consumption, installation simplicity, waterproof performance and the like to different extents, and a novel induction technology is urgently needed, which can overcome the above disadvantages and realize a bathroom induction solution with high efficiency, accuracy, low cost, low power consumption and easy installation and maintenance.

Limitations of the prior art are as follows:

Wherein:

For this purpose, as shown in fig. 1 to 9, the background suppressing bathroom sensor according to the present invention includes a transmitting module 200 mounted on a base 100, and a receiving module 300 mounted on the base 100, wherein the base 100 is mounted on a bathroom device, the transmitting module 200 includes a light emitting element 210 and a transmitting lens 220, the light emitting element 210 is used for emitting light, and the transmitting lens 220 is located on the transmitting side of the light emitting element 210 to focus the light and direct the light outwards. In addition, the receiving module 300 includes a first position sensor 310, a second position sensor 320, and a receiving lens 330, and the receiving lens 330 is located at front ends of the first position sensor 310 and the second position sensor 320. In some applications, the receiving lens 330 is used to focus light reflected back from a first range of distances in front of the light emitting element 210 and directed toward the first position sensitive element 310 to communicate with the bathroom fixture and actuate the operation of the bathroom fixture. In some applications, the receiving lens 330 is used to focus light reflected back from a shield located at a second distance range that is rearward of the first distance range and directed toward the second position-sensitive element 320 to interrupt communication with the bathroom fixture and to urge the bathroom fixture to remain closed. It is easy to understand that the back view object 500 is in front of the transmitting module 200, when the object 400 enters a suitable position between the transmitting module 200 and the back view object 500, i.e. within a first distance range in front of the light emitting element 210, the object 400 can shade the light emitted by the light emitting element 210 and reflect the light to the first position sensing element 310, so as to send out a sensing signal to start the bathroom device for a user to use. It should be noted that, through integrating the transmitting module 200, the first position sensing element 310, the second position sensing element 320, and the transmitting lens 220 and the receiving lens 330, accurate and stable control of the bathroom device is achieved, limitations of the traditional sensing technology are effectively overcome, wherein, focusing and orientation of light are ensured by using the transmitting lens 220, utilization efficiency of light is improved, external interference is reduced, sensing distance is more accurately controllable, and design of the receiving lens 330 allows different sensing requirements to be adapted through adjustment, stable sensing effect is ensured regardless of light or dark objects, whether in a strong light or weak light environment, in addition, intelligent management of the operation state of the bathroom device is achieved by matching the double PD sensors of the first position sensing element 310 and the second position sensing element 320, embarrassment that the bathroom device is not started in place or not started in place is avoided, energy consumption is also reduced, intelligent level and user experience of the device are improved, and the sensing accuracy, adaptability, durability and energy saving are remarkably improved.

Referring again to fig. 1, the base 100 has a first cavity 101, a second cavity 102, and a cavity wall 110 separating the first cavity 101 and the second cavity 102, the cavity opening of the first cavity 101 and the cavity opening of the second cavity 102 are disposed toward the same side of the base 100, the light emitting element 210 is disposed in the first cavity 101, and the first position sensing element 310 and the second position sensing element 320 are disposed in the second cavity 102. It can be appreciated that the cavity wall 110 can isolate the light emitting element 210 from the first position sensing element 310 and the second position sensing element 320, so that the cavity wall 110 can isolate the light emitted by the light emitting element 210, thereby avoiding the sensor sensing error caused by the light emitted by the light emitting element 210 being refracted to the first position sensing element 310 or the second position sensing element 320 in the base 100, improving the definition of the signal, and ensuring the high precision and stability of the sensor. In some specific embodiments, the first cavity 101 is funnel-shaped, the light emitting element 210 is mounted at a small end of the first cavity 101, the cavity opening of the first cavity 101 is located at a large end of the first cavity 101, and the light emitting element 210 emits light in a direction of the cavity opening of the first cavity 101, so that the side wall of the first cavity 101 is prevented from shielding the light emitted by the light emitting element 210, and the funnel-shaped structure enables the light emitted by the light emitting element 210 to be effectively converged to form a narrower and more concentrated light beam, so that the penetrating power and the sensing range of the light are enhanced, meanwhile, the light is ensured to be accurately projected to a target area according to a preset direction, and energy loss is reduced.

Referring to fig. 2, in some embodiments of the present invention, the second cavity 102 extends obliquely in the direction of the cavity opening, and the cavity opening of the second cavity 102 is inclined in the direction close to the first cavity 101, so that the second cavity 102 can incline following the inclination of the reflected light, and the side wall of the second cavity 102 is prevented from shielding the reflected light, so that the receiving lens 330 can better capture the reflected light, and the receiving efficiency is improved. Meanwhile, the inclination of the cavity port helps to prevent water, reduces the possibility of moisture or other liquid entering the receiving module 300, and enhances the waterproof performance and durability of the whole system.

In some embodiments of the invention, a background suppression bathroom sensor is used to control the opening of water. Specifically, the bathroom device is provided with a water outlet mechanism and the electromagnetic valve 900 arranged in the water outlet mechanism, the first position sensitive element 310 is communicated with the electromagnetic valve 900 to drive the water outlet mechanism to be opened, and the second position sensitive element 320 is interrupted from being communicated with the electromagnetic valve 900 to drive the water outlet mechanism to be closed, so that the instant response and the accurate control of the bathroom device are realized, the waste of water resources is reduced, and the user experience is improved.

In some embodiments, the receiving lens 330 is adjustably mounted to the base 100 to adjust the position of the first distance range. The sensor allows a user to adjust the sensing distance according to the actual use environment, enhances the adaptability and flexibility of the sensor, and meets the requirements of different scenes and user preferences. Specifically, the second position sensor 320 is located on the side of the first position sensor 310 facing the light emitting element 210, and in application, moving the receiving lens 330 to the left shortens the detection distance, moving the receiving lens 330 lengthens the detection distance, decreases the distance between the receiving lens 330 and the position sensor, decreases the detection distance, and increases the detection distance by lifting the distance between the receiving lens 330 and the position sensor.

Referring to fig. 3 and 4 again, in some embodiments of the present invention, the bathroom device is a faucet 600, the faucet 600 includes a standpipe portion 610 and a horizontal tube portion 620 connected to the top end of the standpipe portion 610, the bottom end of the standpipe portion 610 is used for water inflow, the bottom of one end of the horizontal tube portion 620 far away from the standpipe portion 610 is provided with a water outlet 6202, the bottom of the horizontal tube portion 620 is provided with a mounting hole 6201, the mounting hole 6201 is located at one side of the water outlet 6202 near the standpipe portion 610, and the base 100 is mounted in the mounting hole 6201. On the other hand, the base 100 can avoid the lower side of the water outlet 6202, so that the base 100 can avoid the hand from being prevented from being stretched to the lower side of the water outlet 6202 by a user to wash hands. Alternatively, the solenoid valve 900 is used to open and close the water outlet 6202, so that the water outlet 6202 of the base 100 can be controlled to be opened and closed by the solenoid valve 900, thereby eliminating the need to manually open and close the water outlet 6202 and further facilitating use.

In some specific embodiments, the bottom of the cross tube 620 is provided with a convex ring protruding downward, and the convex ring is used to form the water outlet 6202, so that the water outlet 6202 can protrude out of the bottom surface of the cross tube 620, and further, the user can conveniently identify the position of the water outlet 6202. Further, the bottom end of the axis of the water outlet 6202 is inclined towards the direction far away from the vertical pipe portion 610, so that the water outlet direction of the water outlet 6202 can be inclined towards the direction close to the user, and further, the user does not need to stretch hands into the position right below the water outlet 6202 to wash hands when washing hands, and the experience of using is improved. Specifically, the bottom end of the axis of the water outlet 6202 is inclined by 5±2 degrees in a direction away from the standpipe portion 610, so that the water outlet inclination angle of the water outlet 6202 is controlled in a smaller angle range, and the water outlet 6202 is prevented from being sprayed to the body of the user due to the overlarge water outlet inclination angle. In some embodiments, the outer wall of the collar transitions with the bottom arc of the cross tube 620, thereby making the appearance of the connection of the collar to the cross tube 620 more aesthetically pleasing. In some embodiments, the cross tube portion 620 and the standpipe portion 610 are perpendicular to each other, thereby providing an aesthetically pleasing appearance to the body. Optionally, the inner angle of the connection between the horizontal pipe 620 and the vertical pipe 610 is rounded, so that the corner of the connection between the horizontal pipe 620 and the vertical pipe 610 is reduced, and the outer pipe of the body is smoother and more beautiful.

It can be appreciated that when the sensor detects that the shielding object exists, the electromagnetic valve 900 can be controlled to open the water outlet 6202, so that the effect of automatically sensing the water opening and closing of the faucet 600 is realized, meanwhile, the sensor has the advantages of accurate detection and low cost, the shielding object can be accurately detected, the sensing accuracy is high, the water spraying when the shielding object is not in place is avoided, and the water spraying when the shielding object is not in place is avoided. Specifically, the first distance range is a set water outlet sensing distance range, and the second distance range is a set distance range exceeding the water outlet sensing distance.

Further, the mounting hole 6201 is a waist-shaped hole, so that, on one hand, the mounting hole 6201 can be matched with the shape of the base 100, and on the other hand, the mounting position of the base 100 on the mounting hole 6201 can be conveniently adjusted, and further, the position of the base 100 on the transverse tube 620 can be adjusted. In some specific embodiments, the length direction of the mounting hole 6201 is set along the length direction of the transverse tube 620, so that the position of the base 100 can be adjusted along the length direction of the mounting hole 6201, and further, the distance between the base 100 and the water outlet 6202 can be conveniently adjusted. In some specific embodiments, the line connecting the center of the mounting hole 6201 and the center of the water outlet 6202 is parallel to the length direction of the lateral tube portion 620, such that when a user stretches his hand from the direction of the water outlet 6202 away from the standpipe portion 610 to the water outlet 6202, the user's hand can enter the detection area of the base 100 along the direction of stretching his hand, so that the base 100 mounted on the mounting hole 6201 can detect his hand in time.
