[0031] With the continuous advancement of technology and people's increasing demands for living standards, smart toilets are becoming more and more widely used. Most smart toilets are equipped with a seat sensor, which generates a signal when it detects a person sitting on the toilet seat, causing the smart toilet to automatically activate the corresponding functions. In related technologies, the top surface of the toilet seat is usually sloped to better conform to ergonomics and improve the user's sitting experience; however, the slope affects the contact area between the seat sensor and the seat cover, leading to a decrease in the accuracy of the seat sensor's detection results.

[0032] This utility model proposes a toilet seat ring, aiming to solve the technical problem of how to improve the detection accuracy of the seat sensor 40.

[0033] In the embodiments of this utility model, such as Figures 1 to 3 As shown, the toilet seat includes: an upper shell 10, which includes a top shell plate 11, the outer periphery of which is higher than its inner periphery, and the top shell plate 11 extends downward from the outer periphery to the inner periphery; a lower shell 20, which is connected to the bottom of the upper shell 10 and together with the upper shell 10 forms a receiving cavity 21; a sensor bracket 30, which is installed in the receiving cavity 21, and has an upwardly inclined support surface 31, which is parallel to the lower plate surface of the top shell plate 11; and a seating sensor 40, which is installed on the sensor bracket 30 and is used to generate a sensing signal when a human body is detected sitting on the upper shell 10; the bottom surface of the seating sensor 40 abuts against the support surface 31, and the top surface of the seating sensor 40 abuts against the lower plate surface of the top shell plate 11.

[0034] In this embodiment, the toilet seat is arranged in a ring shape, with an outer ring that is U-shaped and an inner ring that is figure-eight or gourd-shaped. The toilet seat is formed by splicing an upper shell 10 and a lower shell 20. When the toilet seat is in use, the lower shell 20 abuts against the toilet body, and the upper shell 10 is provided for the user to sit on when using the toilet. When the user sits on the upper shell 10, the seat sensor 40 can detect this seated state and generate a sensing signal. The sensing signal is transmitted to the main control board of the smart toilet and triggers the corresponding functions of the smart toilet, such as putting the smart toilet into standby mode or automatically heating the toilet seat.

[0035] The seating sensor 40 can be a capacitive sensor. When a human body comes into contact with the top shell plate 11 of the upper shell 10, the difference in dielectric constant between the human body and the seating sensor 40 will cause a change in capacitance. This change is detected by the sensor and converted into an electrical signal.

[0036] The top shell plate 11 of the upper shell 10 extends downwards from the outer periphery to the inner periphery. Both the upper and lower surfaces of the top shell plate 11 extend downwards from the outer periphery to the inner periphery, ensuring a consistent wall thickness from the outer to the inner periphery. The support surface 31 of the sensor bracket 30 is parallel to the lower surface of the top shell plate 11. After the bottom surface of the seated sensor 40 overlaps the support surface 31, the seated sensor 40 is tilted so that its top surface can effectively abut against the lower surface of the top shell plate 11, thereby increasing the effective detection area of ​​the seated sensor 40 and ensuring its detection effect. Because the seated sensor 40 is installed at an angle, the consistent wall thickness of the top shell plate 11 from the outer to the inner periphery is ensured, reducing internal stress and improving the structural strength of the top shell plate 11.

[0037] Specifically, such as Figure 4 and Figure 5 As shown, the sensor bracket 30 has a mounting groove 32, the support surface 31 is disposed within the mounting groove 32, and the seated sensor 40 is mounted in the mounting groove 32, with the top surface of the seated sensor 40 protruding from the opening of the mounting groove 32. The mounting groove 32 increases the mating area between the seated sensor 40 and the sensor bracket 30, thereby improving the installation stability of the seated sensor 40 on the sensor bracket 30.

[0038] In practical applications, such as Figure 4 and Figure 5 As shown, a reinforcing rib 33 protrudes from the bottom of the mounting groove 32, and the top surface of the reinforcing rib 33 forms the support surface 31. The reinforcing rib 33 can improve the structural strength of the sensor bracket 30, thereby further ensuring the installation stability of the seated sensor 40. The reinforcing rib 33 may include a first rib and a second rib that intersect horizontally and vertically, thereby further improving the structural strengthening effect of the reinforcing rib 33 on the sensor bracket 30.

[0039] The sensor bracket 30 can be connected to the upper shell 10 or the lower shell 20, and there is no restriction on this.

[0040] For example, such as Figure 3 As shown, the sensor bracket 30 is connected to the top shell plate 11. In this way, it can be ensured that the seated sensor 40 can abut against the lower surface of the top shell plate 11 after being installed on the sensor bracket 30, and the height of the seated sensor 40 can be reduced to simplify the structure of the seated sensor 40.

[0041] Specifically, such as Figure 4As shown, the side wall of the sensor bracket 30 is provided with a connecting lug 34, and the connecting lug 34 has a through hole 341; the lower plate surface of the top shell plate 11 is provided with a fixing post 12, and the end of the fixing post 12 has a fixing hole 121. The through hole 341 and the fixing hole 121 are connected by fasteners.

[0042] The fixing hole 121 can be a screw hole, and the fastener can be a screw. The fastener passes through the through hole 341 and is fixedly connected to the fixing hole 121 to achieve a fixed connection between the sensor bracket 30 and the upper shell 10. There can be two connecting lugs 34, which protrude from opposite sides of the sensor bracket 30. Each connecting lug 34 has a through hole 341. The number and position of the fixing posts 12 correspond to the connecting lugs 34. Each fixing post 12 has a fixing hole 121 at its end. Each connecting lug 34 is connected to each fixing post 12, which increases the connection points between the sensor bracket 30 and the top shell 11, thereby improving the installation stability of the sensor bracket 30.

[0043] In practical applications, such as Figure 4 and Figure 5 As shown, the connecting lug 34 and the sensor bracket 30 are integrally formed, for example, they can be integrally injection molded. This simplifies the connection method between the connecting lug 34 and the sensor bracket 30 and improves the connection strength between the connecting lug 34 and the sensor bracket 30.

[0044] For example, such as Figure 2 and Figure 3 As shown, the upper surface of the top shell plate 11 has a convex arc surface, while the area on the lower surface of the top shell plate 11 that abuts against the seating sensor 40 is planar. The convex arc surface of the upper surface of the top shell plate 11 increases the contact area between the upper shell 10 and the user's body, thus improving the user's seating experience. The lower surface of the top shell plate 11 has a concave arc surface corresponding to the upper surface, ensuring consistent wall thickness across all parts of the top shell plate 11. Only the area on the lower surface of the top shell plate 11 that abuts against the seating sensor 40 is planar; this ensures sufficient contact area between the lower surface of the top shell plate 11 and the seating sensor 40 while minimizing the impact on the overall wall thickness of the top shell plate 11.

[0045] Specifically, such as Figure 4As shown, a positioning groove 111 is provided on the lower surface of the top shell plate 11, and the top of the seat sensor 40 is disposed in the positioning groove 111. The bottom of the positioning groove 111 is flat. When fixing and installing the seat sensor 40 and the sensor bracket 30, the seat sensor 40 can be pressed into the positioning groove 111 first, thus ensuring the accurate installation position of the seat sensor 40. In addition, the positioning groove 111 can also limit the seat sensor 40, preventing the seat sensor 40 from easily shifting from the area abutting against the upper shell 10 during the process of the toilet seat being flipped up and down, thereby further improving the installation stability of the seat sensor 40 in the toilet seat.

[0046] This utility model also proposes a smart toilet, which includes a toilet body and a toilet seat. The specific structure of the toilet seat is as described in the above embodiments. Since this smart toilet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0047] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
