Thermostatic toilet seat, seating signal collection method and temperature control method

Abstract

The invention discloses a thermostatic toilet seat, which comprises a seat base layer, a heating layer and an insulating layer in sequence. The heating layer and the insulating layer are arranged above the seat base layer. The heating layer is a heat generating film formed by curing the wire paste printed on the base layer. The thermostatic toilet seat also comprises a safety special low-voltage DC power supply used for supplying power to the heat generating film. The insulating layer adopts resin paint with a curing hardness greater than 2H, and the thickness of the insulating layer is less than 0.5mm. Through eliminating the temperature control sensor and seating sensor on the traditional toilet seat, the overall cost is reduced. The thermal conduction distance of the heat generating film to the surface of the seat is reduced, so that the corresponding temperature rises faster while using less power for heating in an efficient and safe way. The surface of the toilet seat is high andmore scratch-resistant, and the structure is simpler. The thermostatic toilet seat is easy to produce with simple process, and the production cost is low.

Description

technical field [0001] The invention belongs to the field of toilet seats, and more specifically relates to a constant temperature seat ring, a seat signal acquisition method and a temperature control method. Background technique [0002] With the development of science and technology and the improvement of living standards, smart toilets are gradually being understood by the public and have begun to enter ordinary families. The seat of the smart toilet generally has the functions of temperature detection, seat detection, and heating power control to achieve constant temperature control. In order to achieve these functions, the seat shell is made of thermoplastic material injection molding, which is divided into two parts, the upper shell 1 and the base, such as Figure 1-4 As shown, the inner surface of the upper shell 1 is integrated with a temperature sensor 4, a seating sensor 3, a heat-conducting aluminum foil 5, and a heating wire 2. The upper shell and the base are fi...

AI Technical Summary

Problems solved by technology

[0004] 1. The seat ring is a hollow plastic shell with upper and lower parts bonded. The production process is more complicated, with many procedures, and the strength of the bonding part is weak, and it is easy to fatigue and crack after long-term use;

[0005] 2. The heating wire is powered by 220V AC, which has certain safety risks. It is necessary to pay attention to the insulation of the seat ring, and prevent water from entering the bonding part;

[0006] 3. Some sensitive people will feel the AC induction on the surface of the seat ring, causing panic and anxiety;

[0007] 4. Taking into account the weight of the human body, the upper shell of the seat ring is relatively thick, generally more than 3.5mm, the section of the heating wire is circular, and the heating wire is covered with an insulating skin of more than 1mm, resulting in very slow heat conduction, the surface of the seat ring The temperature rise rate is very slow, and it takes 2 minutes to reach the set temperature under full power heating, and it cannot be made into an instant heating seat;

[0008] 5. In order to speed up the temperature rise, some designs use high-power heating wires, which may easily cause safety problems such as overheating and burning;

[0009] 6. Regardless of whether PP or ABS is used, the surface hardness of the seat ring is not enough, generally 1B or HB, and it is easy to leave scratches during use;

[0010] 7. The seat ring is relatively thick and bulky, the appearance design is limited, and it is not beautiful;

[0011] 8. There are many parts, the process is complicated and the cost is high
