Description

Technical fields:

[0001] This utility model belongs to the field of intelligent toilet technology, and specifically refers to a micro switch for toilet seat engagement. Background technology:

[0002] Currently, most smart toilets feature seat heating and automatic flushing. To enhance their intelligence, sensor stickers are affixed to designated areas on the upper surface of the seat to indicate that the user's buttocks must contact this area to activate the seat sensor switch and automatically start the heating and flushing functions. However, this sensor switch structure is limited by human contact. Children and people with certain medical conditions may not be able to properly activate the washing function because their bodies cannot cover this area. Summary of the Invention:

[0003] The purpose of this invention is to provide a micro-switch for toilet seat rings, which uses a combination of a capacitive inductive switch and a metal sensing element. As long as the seat is pressed down on the main body of the seat ring, the inductive switch can be triggered accurately and stably.

[0004] This utility model is implemented as follows:

[0005] A toilet seat micro switch includes a stationary induction bracket disposed on the bottom surface of the seat body and a movable induction bracket disposed below the stationary induction bracket. The movable induction bracket is movably fitted to the bottom of the stationary induction bracket, and a return spring is provided between the stationary induction bracket and the movable induction bracket, which has elasticity to separate the stationary induction bracket and the movable induction bracket. An induction switch is disposed on the seat body, and a metal sensing element corresponding to the position of the induction switch is disposed on the movable induction bracket. When the metal sensing element approaches the induction switch, it causes a change in the capacitance of the induction switch, thereby generating a switch signal.

[0006] In the aforementioned toilet seat micro switch, the seat body includes an upper shell seat and a lower shell seat that are stacked and spliced ​​together, forming a sealed electrical cavity between the upper shell seat and the lower shell seat. The inductive switch is located in the electrical cavity. A sensing receiving groove is provided on the bottom surface of the lower shell seat. The sensing static bracket is located in the sensing receiving groove, and the bracket screw passes through the sensing static bracket from bottom to top and is screwed to the bottom surface of the sensing receiving groove.

[0007] In the aforementioned toilet seat micro switch, the bottom surface of the sensing bracket is connected to a force-bearing rubber pad, and the bottom of the force-bearing rubber pad extends beyond the opening of the sensing receiving groove.

[0008] In the aforementioned toilet seat micro switch, a fixing groove is provided on the top surface of the lower housing seat, and a sensing groove communicating with the sensing receiving groove is provided on the bottom surface of the fixing groove. The sensing switch is set in the sensing groove, and the fixing groove is connected to a sensor pressure plate that prevents the sensing switch from detaching from the sensing port by a pressure plate screw.

[0009] In the aforementioned toilet seat micro switch, the sensing static bracket has a limit window vertically, the sensing moving bracket is provided with a linkage support plate, and the linkage support plate is provided with a movable block that engages with a buckle and can move vertically along the limit window.

[0010] In the aforementioned toilet seat micro switch, there are three or more limiting windows distributed circumferentially, and the number and position of the linkage support plate and movable block correspond one-to-one with the limiting windows. There are two or more reset springs.

[0011] In the aforementioned toilet seat micro switch, the metal sensing element is a plate structure, and a conductive foam plate is provided on the end face of the metal sensing element facing the induction switch.

[0012] The outstanding advantages of this utility model compared to the prior art are:

[0013] This utility model has a simple structure, reasonable design, and low cost. It adopts a capacitive inductive switch and a metal inductive element in combination, which can accurately and stably trigger the inductive switch. That is, the user only needs to press down on the seat ring body. As the inductive moving bracket and the inductive stationary bracket move relative to each other, the metal inductive element approaches the inductive switch, causing a change in the capacitance of the inductive switch, thereby generating a switch signal.

[0017] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —2:

[0018] A toilet seat micro switch includes a static induction bracket 1 disposed on the bottom surface of the seat body and a movable induction bracket 2 disposed below the static induction bracket 1. The movable induction bracket 2 is movably fitted to the bottom of the static induction bracket 1, and a return spring 3 is provided between the static induction bracket 1 and the movable induction bracket 2, which has elasticity to separate the static induction bracket 1 and the movable induction bracket 2. A sensor switch 4 is disposed on the seat body, and a metal sensing element 5 corresponding to the position of the sensor switch 4 is disposed on the movable induction bracket 2.

[0019] This utility model has a simple structure, reasonable design and low cost. It adopts the capacitive sensing switch 4 and the capacitive sensing of the metal sensing element 5 to accurately and stably trigger the sensing switch 4. That is, the user only needs to press down on the seat ring body. Under the relative displacement of the sensing moving bracket 2 and the sensing stationary bracket 1, the metal sensing element 5 approaches the sensing switch 4 to cause the capacitance of the sensing switch 4 to change, thereby realizing the generation of the switching signal.

[0020] Considering that the inductive switch 4 is easily affected by external environmental humidity and pollution, which reduces its sensitivity, the main body of the seat ring includes an upper shell seat ring 6 and a lower shell seat ring 7 stacked together. A sealed electrical cavity is formed between the upper shell seat ring 6 and the lower shell seat ring 7, and the inductive switch 4 is located within this electrical cavity. A sensing receiving groove is formed on the bottom surface of the lower shell seat ring 7, and the sensing stationary support 1 is located within the sensing receiving groove. A support screw 8 passes through the sensing stationary support 1 from bottom to top and is screwed onto the bottom surface of the sensing receiving groove. This effectively solves the problem of the inductive switch 4's weak anti-interference ability by placing the inductive switch 4 between the upper shell seat ring 6 and the lower shell seat ring 7, which are sealed and separated from the outside environment.

[0021] Furthermore, to prevent the sensor support 2 from being damaged by frequent friction with the ceramic base, a force-bearing rubber pad 9 is connected to the bottom surface of the sensor support 2, and the bottom of the force-bearing rubber pad 9 extends out of the groove of the sensor receiving groove.

[0022] In order to ensure that the inductive switch 4 can be stably mounted on the lower housing ring 7, a fixing groove 10 is provided on the top surface of the lower housing ring 7, and an inductive groove 11 communicating with the inductive receiving groove is provided on the bottom surface of the fixing groove 10. The inductive switch 4 is set in the inductive groove 11, and the fixing groove 10 is connected to a sensor pressure plate 13 that can prevent the inductive switch 4 from detaching from the sensing port through a pressure plate screw 12.

[0023] Meanwhile, the vertical movement between the stationary sensing bracket 1 and the moving sensing bracket 2 can be a hinge mechanism, meaning one side of the moving sensing bracket 2 is hinged to the stationary sensing bracket 1, while the other side is a free end connected to the corresponding side of the stationary sensing bracket 1 via a return spring 3. In this embodiment, the specific structure of the vertical movement between the stationary sensing bracket 1 and the moving sensing bracket 2 is as follows: the stationary sensing bracket 1 has a limiting window 14 vertically, the moving sensing bracket 2 is provided with a linkage support plate 15, and the linkage support plate 15 is provided with a movable locking block 16 that engages with the limiting window 14 and can move vertically along the limiting window 14. Furthermore, there are three or more limiting windows 14 distributed circumferentially, and the number and position of the linkage support plate 15 and the movable locking block 16 correspond one-to-one with the limiting windows 14. There are two or more return springs 3.

[0024] In addition, to avoid dimensional deviations in the metal sensing element 5 caused by processing and assembly, which could affect the inductive switch 4, the metal sensing element 5 is a plate structure. A conductive foam plate 17 is provided on the end face of the metal sensing element 5 facing the inductive switch 4. That is, the conductive foam plate 17 can both buffer and ensure that it does not reduce the charge on the inductive switch 4.

[0025] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
