Description

Technical Field

[0001] This utility model relates to the field of capacitive foot-sensing technology, specifically to an exposed capacitive foot-sensing device for a smart toilet. Background Technology

[0002] Capacitive foot-sensing technology is based on the principle of capacitive sensing. In a capacitive foot-sensing device, electrodes are usually installed under the seat or footrest area of ​​a smart toilet, while the human body acts as another electrode. When a human body approaches or touches the capacitive foot-sensing area, a capacitance is formed between the human body and the electrode. Since the human body is a conductor, it changes the electric field distribution between the electrode and the ground, thereby affecting the capacitance value. The capacitive foot-sensing circuit monitors the change in this capacitance value and determines whether someone is approaching based on the change, thereby triggering functions such as raising or lowering the toilet seat, opening or closing the seat, or starting the flushing function.

[0003] In existing technologies, capacitive foot sensor functions are usually enabled by default on smart toilets. However, the exposed capacitive foot sensors on existing smart toilets generally have a short sensing distance during use. Users need to get very close to the sensor to trigger the corresponding function, which is inconvenient and affects the user experience. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an exposed capacitive foot sensor for a smart toilet, which solves the problem that most existing exposed capacitive foot sensors for smart toilets have a short sensing distance during use, requiring users to be very close to the sensor to trigger it.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an exposed capacitive foot sensor for a smart toilet, comprising a housing shell composed of an upper shell and a lower shell bonded together, an end cap provided at the outer end of the housing shell, a capacitive sensing PCB board provided at the outer end of the inner cavity of the housing shell, and conductive silicone filling the space between the capacitive sensing PCB board and the end cap.

[0006] The outer ends of the sidewalls of the upper housing and the lower housing are provided with convex sides, and the two convex sides form an convex annular portion. The inner end of the housing is provided with a wiring structure.

[0007] Furthermore, the wiring structure includes a connecting wire and a rubber sleeve. The connecting wire is disposed in the inner cavity of the housing and one end is electrically connected to the capacitive sensing PCB board. The other end of the connecting wire extends to the outside of the housing. The rubber sleeve is fixedly connected to one end of the surface of the connecting wire.

[0008] Furthermore, the surface of the rubber sleeve is provided with a plurality of bending grooves, and the plurality of bending grooves are evenly spaced and distributed along the surface of the rubber sleeve.

[0009] Furthermore, one end of the outer surface of the rubber sleeve is provided with an annular portion, and the inner end of the inner wall of the receiving housing is provided with a locking portion adapted to the annular portion.

[0010] Furthermore, the inner cavity of the housing is provided with a mounting bracket adapted to the capacitive sensing PCB board, and the inner end of the outer surface of the mounting bracket is fixedly connected with two sealing rings that abut against the inner wall surface of the housing.

[0011] Furthermore, a sensor port is provided on the end cap.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: by incorporating conductive silicone, the sensing distance of the capacitive sensing PCB board is increased. The longer sensing distance allows users to trigger relevant functions without having to press their hands against the toilet, improving ease of use and enabling faster response and activation of toilet functions, saving users time and enhancing the overall user experience. Furthermore, the protruding side improves the fit and sealing between the housing and the toilet, effectively preventing moisture and humidity from entering the toilet, thus extending the toilet's lifespan. The electronic components, mechanical parts, and housing inside the toilet are less susceptible to moisture and corrosion, reducing the frequency of repairs and replacements, and lowering maintenance and operating costs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an exposed capacitive foot sensor for a smart toilet, comprising a housing 1 consisting of an upper housing 2 and a lower housing 3 bonded together, an end cap 5 provided at the outer end of the housing 1, a capacitive sensing PCB board 12 provided at the outer end of the inner cavity of the housing 1, and conductive silicone 13 filling the space between the capacitive sensing PCB board 12 and the end cap 5.

[0019] The outer ends of the side walls of the upper housing 2 and the lower housing 3 are provided with protruding side edges 4. The two protruding side edges 4 form a protruding annular part, and the inner end of the housing 1 is provided with a wiring structure.

[0020] The conductive silicone 13 increases the sensing distance of the capacitive sensing PCB board 12. The longer sensing distance allows users to trigger related functions without having to press their hands against the toilet, improving ease of use and enabling faster response and activation of the toilet's related functions, saving users time and enhancing the overall user experience.

[0021] The two protruding side edges 4 form a protruding annular portion, which can improve the fit between the housing 1 and the toilet, and improve the sealing between the housing 1 and the toilet. This can effectively prevent water vapor and moisture from entering the toilet, thereby extending the service life of the toilet.

[0022] The electronic components, mechanical parts, and housing inside the toilet are less susceptible to moisture and corrosion, reducing the frequency of repairs and replacements, and lowering the maintenance and operating costs of the toilet.

[0023] The wiring structure includes a connecting wire 9 and a rubber sleeve 8. The connecting wire 9 is located in the inner cavity of the housing 1, and one end is electrically connected to the capacitive sensing PCB board 12. The other end of the connecting wire 9 extends to the outside of the housing 1. The rubber sleeve 8 is fixedly connected to one end of the surface of the connecting wire 9. The rubber sleeve 8 improves the anti-bending performance of the connecting wire 9 and extends the service life of the rubber sleeve 8.

[0024] The surface of the rubber sleeve 8 is provided with several bending grooves. The multiple bending grooves are evenly distributed and spaced along the surface of the rubber sleeve 8. The bending grooves facilitate the slight bending of the rubber sleeve 8 and prevent the rubber sleeve 8 from cracking easily.

[0025] One end of the outer surface of the rubber sleeve 8 is provided with a ring portion 10, and the inner end of the inner wall of the housing 1 is provided with a locking portion 11 that is adapted to the ring portion 10.

[0027] The inner cavity of the housing 1 is provided with a mounting bracket 6 that is compatible with the capacitive sensing PCB board 12. Two sealing rings 7 that abut against the inner wall of the housing 1 are fixedly connected to the inner end of the outer surface of the mounting bracket 6. The end cover 5 is provided with a sensing port 14. The two sealing rings 7 effectively improve the sealing performance of the inner cavity of the housing 1.

[0028] During operation, the conductive silicone 13 increases the sensing distance of the capacitive sensing PCB board 12. The longer sensing distance allows users to trigger related functions without having to press their hands against the toilet, improving ease of use and enabling faster response and activation of the toilet's functions. This saves users time and enhances the overall user experience. Furthermore, the protruding side 4 improves the fit between the housing 1 and the toilet, enhancing the seal between them. This effectively prevents moisture and humidity from entering the toilet, thus extending its lifespan. The electronic components, mechanical parts, and housing 1 inside the toilet are less susceptible to moisture and corrosion.
