[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0032] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0033] Reference Figures 1 to 9 As shown, a smart toilet capacitive foot sensor includes a fixing base 1 and a sensing base 2. The fixing base 1 is pre-buried in the toilet, and the sensing base 2 is inserted into the fixing base 1 and detachably connected thereto. One end surface of the sensing base 2 is exposed to the outside of the toilet. When the sensing base 2 needs to be disassembled and repaired, the sensing base 2 can be removed from the fixing base 1 along the direction in which the sensing base 2 is exposed to the outside of the toilet, thereby achieving simple disassembly and then repairing the sensing base 2.

[0034] The sensor base 2 includes a light-transmitting shell 21 and a sensor 22. The light-transmitting shell 21 includes a light-transmitting surface 213. The sensor 22 is provided with an LED indicator light 2212. The light of the LED indicator light 2212 can be transmitted through the light-transmitting surface 213. By observing the LED indicator light 2212 from the outside, it can be determined whether the sensor base 2 is working normally.

[0035] The sensor 22 includes a circuit board A221, a circuit board B222, and a bracket 223 for separating and supporting the circuit boards A221 and B222. The LED indicator light 2212 is arranged on the top of the circuit board A221, and the bottom of the circuit board A221 is provided with an induction coil 2211. The induction coil 2211 forms a discrete capacitor through a virtual ground loop. When a human body or a conductive object approaches the induction coil 2211, the discrete capacitor increases, and the sensor 22 outputs a signal; when the human body or the conductive object leaves, the discrete capacitor decreases, and the sensor 22 does not output a signal. Therefore, when the user extends his foot close to the side wall of the toilet capacitor area, the sensor 22 will be triggered to sense, and the toilet will perform actions such as turning the rim and flushing.

[0036] The bottom of the circuit board B222 is covered with copper material 2221. Since the induction coil 2211 is a three-dimensional spherical structure for releasing the external virtual ground, that is, the induction space of the sensor 22 is a three-dimensional solid sphere with the induction coil 2211 as the center, if it is directly applied to the smart toilet foot sensing device without processing, it will be affected by the toilet structure behind and easily cause false triggering. Therefore, by covering the bottom of the circuit board B222 with copper material 2221, the capacitive sensing effect at this position can be shielded.

[0037] The circuit board A221 and the circuit board B222 are electrically connected, and the electrical connection method includes connection with PIN needles 224 or connection with wires.

[0038] The circuit board A221, the circuit board B222 and the bracket 223 are partially buried in the light-transmitting shell 21 and filled with epoxy sealant to prevent the circuit boards from being corroded by water vapor.

[0039] Reference Fig. 9 As shown, the bracket 223 includes a panel 2231 and a plurality of deformation bars 2232 arranged in a circumferential array around the panel 2231. The deformation bars 2232 extend inward to form a separation step 22321. The free end of the deformation bar 2232 extends inward to form a limit hook 22322. The limit hook 22322 and the separation step 22321 form a first fastening space for fastening the circuit board A221, and the separation step and the panel form a second fastening space for fastening the circuit board B222. The first fastening space and the second fastening space formed by the bracket 223 can provide stable support for the circuit board A221 and the circuit board B222.

[0040] The sensor base 2 includes a light-transmitting shell 21, and the deformation strip 2232 extends outward to form an anti-detachment hook 22323 embedded in the light-transmitting shell 21. The anti-detachment hook 22323 ensures that the bracket 223 is stably connected to the light-transmitting shell 21.

[0041] The fixing seat 1 includes a face frame 11, an elastic member 12, a guide sleeve 13 and a nut 14. The nut 14 is pre-buried in the side wall of the toilet. The outer wall surface of the face frame 11 is provided with an external thread threadedly connected to the nut 14. The elastic member 12 and the guide sleeve 13 are assembled with the face frame 11, and then the face frame 11 and the nut 14 are threadedly locked to achieve the overall assembly of the fixing seat 1.

[0042] Specifically, the elastic member 12 is disposed in the face frame 11, and an annular boss 111 is disposed inside the face frame 11. The elastic member 12 is sleeved on the outer periphery of the annular boss 111. In one embodiment, the elastic member 12 can directly contact the sensing seat 2. In another embodiment, the elastic member 12 can drive the guide sleeve 13, and then drive the sensing seat 2 through the guide sleeve 13. The advantage of this embodiment is that the sensing seat 2 is driven by the guide sleeve 13, which can increase the contact area, and the driving of the sensing seat 2 is more balanced, so that the sensing seat 2 can be ejected more smoothly. Preferably, the elastic member 12 is a compression spring.

[0043] The outer wall surface of the guide sleeve 13 is provided with a hook 131, and the number of the hooks 131 is preferably two and they are symmetrically arranged. The interior of the annular boss 111 of the face frame 11 constitutes a movable part 1111, and the annular boss 111 is provided with a limiting surface 1112 perpendicular to the pop-up direction of the sensing seat 2. The hook 131 is driven in the movable part 1111, and due to the action of the elastic member 12, the hook 131 abuts against the limiting surface 1112.

[0044] The sensor seat 2 is arranged in the face frame 11, and the sensor seat 2 is inserted into the face frame 11 along the axial direction of the face frame 11, and the sensor seat 2 can be switched between the locked position and the unlocked position by rotating. When the sensor seat 2 is rotated to the locked position, the appearance surface of the sensor seat 2 exposed on the outside of the toilet is flush with the appearance surface of the face frame 11 exposed on the outside of the toilet. When the sensor seat 2 is rotated to the unlocked position, the elastic member 12 drives the guide sleeve 13 to move, and the guide sleeve 13 drives the sensor seat 2 to partially pop out, so that the appearance surface of the sensor seat 2 protrudes from the appearance surface of the face frame 11, thereby facilitating the sensor seat 2 to be removed from the toilet and repaired.

[0045] A first stop portion 211 is provided on the outer wall surface of the sensing base 2, and a second stop portion 112 is provided on the inner wall surface of the face frame 11. When the sensing base 2 is rotated so that the first stop portion 211 and the second stop portion 112 cooperate and lock with each other, the sensing base 2 is in a locked position, and the elastic member 12 cannot drive the sensing base 2 to bounce out of the fixing base 1.

[0046] Specifically, the second stop portion 112 includes a first groove 1121 and a second groove 1122, the first groove 1121 and the second groove 1122 are arranged vertically, the first groove 1121 and the second groove 1122 are connected, the inner wall surface of the face frame 11 is provided with the first groove 1121 along the axial extension, the first stop portion 211 is a convex structure, when the first stop portion 211 is inserted along the first groove 1121 and then rotated to abut the second groove 1122, the first stop portion 211 and the second stop portion 112 cooperate with each other to lock, so that the sensing base 2 is in a locked position.

[0047] The second groove 1122 is formed with a clamping bevel 11221, and the first stopper 211 is an L-shaped protrusion, which is partially embedded in and abuts against the clamping bevel 11221. One section of the L-shaped protrusion abuts against the clamping bevel 11221, thereby providing feedback on the rotation position of the sensing seat 2, that is, when rotating to this position, the sensing seat 2 moves along the clamping bevel 11221 so that it will move a short distance toward the outside of the toilet, thereby indicating that the sensing seat 2 has rotated to the locked position. And when the sensing seat 2 rotates from the locked position to the unlocked position, it is necessary to overcome the limiting force of the clamping bevel 11221, thereby preventing the sensing seat 2 from being removed by children or other personnel when the sensing seat 2 does not need to be repaired.

[0048] The outer wall of the face frame 11 facing the sensing seat 2 is provided with a lock mark 113 and an unlock mark 114, and the sensing seat 2 is provided with a directional arrow 212. When the directional arrow 212 is aligned with the lock mark 113, the surface sensing seat 2 is rotated to the lock position. When the directional arrow 212 is aligned with the unlock mark 114, the surface sensing seat 2 is rotated to the unlock position. The lock mark 113 and the unlock mark 114 are used to facilitate the determination of the rotation direction of the sensing seat 2.

[0049] The utility model provides an elastic member 12 and a guide sleeve 13 inside the face frame 11, and the hook 131 of the guide sleeve 13 is fixed to the face frame 11, and the guide sleeve 13 has a certain upward and downward movement space after being assembled, and the sensing seat 2 is inserted into the face frame 11 from the unlocking mark 114 position of the face frame 11, and after being inserted, it is rotated to the left to align with the locking mark 113 position of the face frame 11, and the sensing seat 2 is fixed. When the sensing seat 2 needs to be removed, the sensing seat 2 is rotated to the right, from the locking mark 113 mark of the face frame 11 to the unlocking mark 114 position, and the sensing seat 2 is ejected under the action of the elastic member 12, so that the sensing seat 2 is easy to remove and install.

[0050] As another aspect, the utility model provides a toilet, including a smart toilet capacitive foot sensor.

[0051] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
