Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a seat ring sensing device and a smart toilet. Background Technology

[0002] Current toilet seat sensors generally use capacitive sensors. By touching the corresponding seat position, the sensor determines whether the user has sat down. Capacitive sensors require the user to touch the seat sensing area; otherwise, they cannot detect sitting down. Moreover, when the user cleans the seat with a cloth, it can easily be mistaken for sitting down, thus triggering the flushing function. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a seat ring seating sensing device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0012] The seat ring seating sensing device according to the embodiment of this utility model has at least the following beneficial effects:

[0013] This invention employs a microswitch as a pressure-sensitive switch. When a user sits on the seat, regardless of whether their weight is applied to the front, middle, or rear of the seat, the pressure is transmitted through the seat to the movable plate, triggering the microswitch and improving the restriction of the user's seating area. Because the elastic element has a set force threshold, triggering the switch requires exceeding this threshold, preventing accidental triggering when the user cleans the seat. The sealing sleeve prevents water from entering the seat housing, ensuring the long-term reliability and service life of the microswitch.

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] Reference Figure 1-4 A seat ring seating sensing device, comprising:

[0032] The seat ring housing 100 has an internal cavity 110 and a through hole 120 that communicates with the cavity 110.

[0033] A micro switch 200 is installed in the cavity 110, and the contacts 210 of the micro switch 200 are aligned with the through hole 120.

[0034] 300mm sealing sleeve, 120mm sealing cover for through hole;

[0035] The movable plate 400 is located outside the seat ring housing 100. The movable plate 400 and the seat ring housing 100 are movably engaged. The movable plate 400 and the seat ring housing 100 can move towards each other so that the movable plate 400 triggers the contact 210 of the micro switch 200. The movable plate 400 and the seat ring housing 100 are movably engaged, that is, the movable plate 400 has a certain degree of freedom of movement in the direction perpendicular to the surface of the seat ring, but will not fall off. When subjected to pressure (human weight), the seat ring housing 100 will overcome the elastic force of the elastic element 500 and move towards the movable plate 400.

[0036] The elastic element 500 abuts against the movable plate 400 and the seat ring housing 100. When the person leaves the seat ring (pressure disappears), the elastic element 500 pushes the seat ring housing 100 back to its original position, and the micro switch 200 contacts 210 disconnect and reset. The stiffness (elastic coefficient) and pre-compression of the elastic element 500 directly determine how much force is needed to press the seat ring housing 100 down a sufficient distance to trigger the micro switch 200.

[0037] According to some embodiments of this utility model, the seat ring housing 100 is formed by connecting an upper seat ring housing 130 and a lower seat ring housing 140. The upper seat ring housing 130 and the lower seat ring housing 140 form a cavity 110, and a through hole 120 is formed in the lower seat ring housing 140. A movable plate 400 is installed in the lower seat ring housing 140 as one of the foot pads, and its appearance is no different from that of an ordinary seat ring. The surface of the movable plate 400 is covered with a layer of soft rubber to prevent collisions and noise when the ring is closed.

[0038] In some embodiments of this utility model, the wire of the micro switch 200 reaches the pivot hole of the seat housing 100 along the cavity 110 and is connected to the toilet bowl mechanism through the pivot hole. The wire runs entirely within the enclosed cavity 110 of the seat housing 100, which effectively prevents the wire from being scratched, pulled, or accidentally damaged by external objects, and ensures a clean product appearance with no exposed cables interfering with the visual aesthetics.

[0039] In some embodiments of this utility model, a first mounting groove 150 is formed in the cavity 110, and the micro switch 200 is fixed in the first mounting groove 150. The geometric dimensions of the first mounting groove 150 match the shape of the micro switch 200, defining the mounting position and orientation of the micro switch 200. The micro switch 200 is fixed to the seat housing 100 with screws.

[0040] In some embodiments of this utility model, a second mounting groove 160 is formed on the outer side of the seat housing 100, and a through hole 120 is located in the second mounting groove 160. The outer contour shape of the movable plate 400 is adapted to the shape of the second mounting groove 160, and the movable plate 400 can move in the second mounting groove 160. The side wall of the second mounting groove 160 forms a rigid guide rail, restricting the movable plate 400 to move only in a direction perpendicular to the seat, eliminating the risk of lateral offset or tilting. The side wall of the second mounting groove 160 and the outer periphery of the movable plate 400 are clearance-fitted, ensuring smooth sliding without jamming and preventing shaking and abnormal noise.

[0041] In some embodiments of this utility model, the side wall of the second mounting groove 160 is provided with a protrusion 161, and the edge of the movable plate 400 is provided with a slot 410. The slot 410 is fastened to the protrusion 161, and the protrusion 161 can move within the slot 410. The slot 410 limits the movement but does not lock it. After the protrusion 161 is embedded in the slot 410, it forms a "guide rail-slider" mechanism, forcing the movable plate 400 to move only in one direction.

[0042] In some embodiments of this utility model, the movable plate 400 is provided with a protruding trigger rib 420, which is aligned with the contact 210 of the micro switch 200.

[0043] In some embodiments of this utility model, the movable plate 400 is provided with a protruding positioning rib 430, and the elastic element 500 is a spring. One end of the spring is sleeved on the positioning rib 430, and the other end abuts against the seat ring housing 100. The positioning rib 430 forms a radial constraint on the spring, restricting the spring to be compressed only along the axial direction, thus eliminating the risk of lateral bending.

[0044] In some embodiments of this utility model, the sealing sleeve 300 is in the form of a thin sheet, wrapped around the micro switch 200, and sandwiched between the micro switch 200 and the seat housing 100. The structure of the sealing sleeve 300 is adapted to the contour of the micro switch 200 and fits tightly against the micro switch 200. The sealing sleeve 300 is clamped by the edge of the through hole 120, which not only protects the micro switch 200, but also allows the pressure of the movable plate 400 to be transmitted to the contact 210 of the micro switch 200 without obstruction.

[0045] A smart toilet includes the aforementioned seat placement sensing device.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
