[0033] Reference Figure 1 This utility model provides a heated toilet seat, comprising: a seat body 100, a first insulating protective layer 200, and a silver paste heating layer 300.

[0034] Specifically, the seat ring body 100 is used to connect to the toilet bowl and provides mechanical support to ensure structural stability. A first insulating protective layer 200 is disposed on the upper surface of the seat ring body 100, and the shape and contour of the first insulating protective layer 200 are adapted to the shape and contour of the seat ring body 100. The first insulating protective layer 200 is used to isolate the human body from live parts and also serves as a heat conduction medium to prevent heat from directly losing to the toilet body, thus improving heat utilization. A silver paste heating layer 300 is disposed between the seat ring body 100 and the first insulating protective layer 200. The silver paste heating layer 300 is the main heating element, achieving uniform heat distribution through heating. The silver paste heating layer 300, disposed between the seat ring body 100 and the insulating protective layer, forms a sandwich structure of "base support - high-efficiency heating - safe isolation".

[0035] It should be noted that in the actual product, the seat ring body 100, the silver paste heating layer 300, and the first insulating protective layer 200 are tightly bonded together, and the silver paste heating layer 300 and the first insulating protective layer 200 are sequentially laminated onto the upper surface of the seat ring body 100. (Refer to...) Figure 1To better showcase the sandwich structure formed by the seat body 100, the silver paste heating layer 300, and the first insulating protective layer 200, it was split vertically.

[0036] Specifically, a silver paste heating layer 300 is disposed between the seat body 100 and the first insulating protective layer 200. The silver paste heating layer 300 has excellent electrical and thermal conductivity, enabling efficient current transmission, reducing energy consumption, increasing the heating speed of the toilet seat, and improving heat transfer efficiency compared to traditional heating technologies. Furthermore, the high thermal conductivity of the silver paste heating layer 300 allows for even heat distribution, preventing localized overheating of the toilet seat and enhancing its safety by preventing burns to the user. Additionally, the composite of the silver paste heating layer 300 and the first insulating protective layer 200 on the upper surface of the seat body 100 simplifies the overall structure of the toilet seat and streamlines the manufacturing process.

[0037] In some embodiments, the silver paste heating layer 300 is composed of silver powder, binder, solvent, and additives. The binder is the film-forming material of the silver paste heating layer 300, and different binders vary considerably in viscosity, cohesiveness, adhesion, and thermal properties. Specifically, preferred binders include phenolic resin, epoxy resin, polyurethane resin, acrylic resin, silicone resin, polyvinyl alcohol, and cellulose derivatives. In practical applications, those skilled in the art need to comprehensively consider the substrate on which the silver paste heating layer 300 acts, the curing conditions, and the physicochemical properties of the film-forming material.

[0038] In some embodiments, the solvent of the silver paste heating layer 300 serves the following functions: 1. dissolving the resin to ensure sufficient dispersion of the silver powder in the binder; 2. adjusting the viscosity and viscosity stability of the silver paste; 3. determining the drying speed; 4. improving the surface condition of the substrate, resulting in good adhesion between the paste and the substrate. Specifically, preferred solvents include isopropanol, ethanol, acetone, methyl ethyl ketone, ethyl acetate, butyl acetate, ethylene glycol monoethyl ether, toluene, xylene, water, terpineol, butyl carbitol, butyl solvent anhydride acetate, diethylene glycol butyl ether acetate, diethylene glycol ethyl ether acetate, isophorone, etc.

[0039] In some embodiments, the additives in the silver paste heating layer 300 are mainly used to improve its performance and process characteristics, and commonly include the following categories: 1. Dispersants, which prevent silver particle agglomeration and improve dispersibility, such as polymer dispersants (e.g., polyvinylpyrrolidone PVP) and surfactants (e.g., sodium dodecyl sulfate SDS). 2. Leveling agents, which improve the smoothness of the coating and reduce surface defects, such as silicone leveling agents and acrylic leveling agents. 3. Defoamers, which eliminate bubbles generated during stirring and coating, such as silicone defoamers and mineral oil defoamers. 4. Thickeners, which adjust the viscosity of the silver paste and improve printing performance, such as cellulose derivatives (e.g., hydroxyethyl cellulose HEC) and polyurethane thickeners. 5. Stabilizers, which improve the storage stability of the silver paste and prevent sedimentation and stratification, such as antioxidants (e.g., BHT) and UV stabilizers. 6. Coupling agents, which improve the adhesion between the silver paste and the substrate, such as silane coupling agents (e.g., KH-550) and titanate coupling agents. 7. Wetting agents, which improve the wettability of the silver paste on the substrate and enhance coating uniformity, such as nonionic surfactants (e.g., Tween series) and fluorocarbon wetting agents. 8. Conductivity enhancers, which improve the conductivity of the silver paste, such as graphene and carbon nanotubes. 9. Preservatives, which prevent microbial contamination of the silver paste during storage and use, such as isothiazolinone preservatives and benzisothiazolinones. In practice, those skilled in the art can select appropriate additives based on performance requirements and specific applications.

[0040] Reference Figure 1 , Figure 3 In some embodiments, the silver paste heating layer 300 includes sheet-like silver paste 310. Silver has excellent electrical conductivity, and the conductive network formed by the silver paste enables efficient current transmission, reduces energy consumption, and meets the requirements of rapid response or high-power heating functions for toilets. Furthermore, the low resistance and high thermal conductivity allow the silver paste heating layer 300 to heat up rapidly after being energized, with uniform heat distribution. This not only enables rapid response and uniform heating but also makes it suitable for the precise temperature control required by smart toilets. Additionally, the silver paste is oxidation-resistant, high-temperature resistant, stable, and weather-resistant, with slow performance degradation over long-term use, making it suitable for bathroom environments.

[0041] In some embodiments, the sheet-like silver paste 310 conforms to the shape and contour of the seat body 100, forming a continuous and complete heating surface. This allows current to pass evenly through the entire silver paste layer, avoiding situations where local resistance is too high or too low, thus achieving uniform heating across the entire area. Furthermore, since the sheet-like silver paste 310 covers the entire seat body 100, its thermal field distribution is more stable, resulting in a smaller temperature difference on the toilet seat surface. In terms of manufacturing process, the sheet-like silver paste 310 can be laminated onto the first insulating protective layer 200 using coating, spraying, or printing processes. Of course, the silver paste heating layer 300 can also be designed with other shapes and layouts, as long as it achieves a uniform and efficient heating effect for the toilet seat.

[0042] Reference Figure 1 , Figure 4 In some other embodiments, the silver paste heating layer 300 includes multiple S-shaped silver paste lines 320, which are connected end to end in sequence. The S-shaped curve design allows the silver paste lines to achieve a longer routing length within the limited area of ​​the toilet seat. Without increasing the amount of material used, the S-shaped silver paste lines 320 can increase the heating area, improve heating efficiency, and adapt to different shapes of toilet seat contours, thus improving adaptability.

[0043] Reference Figure 1 , Figure 5 In some other embodiments, the silver paste heating layer 300 includes multiple U-shaped silver paste lines 330. The orthographic projections of these U-shaped silver paste lines 330 are spaced apart, ensuring an effective heating area while allowing for flexible control of heat distribution. Specifically, the spaced U-shaped silver paste lines 330 can form multiple independent heating units on the toilet seat surface. By rationally designing the spacing and power of each unit, differentiated heating effects can be achieved. For example, setting U-shaped silver paste lines 330 of different densities at the front and rear of the toilet seat can specifically increase the temperature of key contact areas, improving comfort while reducing overall energy consumption. Alternatively, the front and rear of the toilet seat can be set with the same density of U-shaped silver paste lines 330 to achieve uniform heating. In actual design, the density of the U-shaped silver paste lines 330 at the front and rear of the toilet seat can be designed according to actual needs.

[0044] Reference Figure 1 , Figure 6In other embodiments, the silver paste heating layer 300 includes multiple linear silver paste lines 340 arranged in a cross-grid pattern to form a crisscrossing heating network. This network creates a uniform heat conduction matrix on the toilet seat surface, improving the uniformity and stability of the toilet seat surface temperature. Furthermore, the cross-grid arrangement of the linear silver paste lines 340 allows current to flow in multiple directions during transmission, preventing localized heating issues caused by single-line faults and improving the reliability of the heating system.

[0045] In some embodiments, the thickness of the silver paste heating layer 300 is 1μm to 200μm. This thickness range ensures a high degree of compatibility between the silver paste heating layer 300 and the first insulating protective layer 200, avoiding delamination problems caused by excessive thickness differences. Furthermore, the seat ring body 100 is made of plastic or wood substrate with a thickness of 5mm to 10mm. The silver paste heating layer 300 with a thickness of 1μm to 200μm does not alter the original structural strength and shape of the seat ring body 100, ensuring installation compatibility.

[0046] In some embodiments, the first insulating protective layer 200 is an insulating polymer film layer, which is bonded to the seat ring body 100 through bonding, hot molding, or in-mold injection molding processes. Specifically, the insulating polymer film layer is a film or sheet material with a softening temperature higher than 60°C. The insulating polymer film layer can be designed as a polyethylene terephthalate film, polycarbonate film, polymethyl methacrylate film, polyimide film, or polyolefin film. Furthermore, the thickness of the insulating polymer film layer is 0.05 mm to 0.5 mm, ensuring insulation performance while also considering heat conduction efficiency.

[0047] In some other embodiments, the first insulating protective layer 200 is a paint layer, which is formed by spraying or baking paint on the seat body 100 and the silver paste heating layer 300. This can prevent the risk of leakage of the silver paste heating layer 300 and ensure user safety.

[0048] In some embodiments, a TPX release film (not shown) is disposed on the upper surface of the first insulating protective layer 200. The TPX release film is a transparent and heat-resistant polyolefin polymer that can provide self-cleaning for the seat surface. In addition, the TPX release film has extremely low surface tension, preventing liquid from wetting the film surface. Instead, liquid forms droplets that roll off, carrying away surface dust and stains, thus achieving physical self-cleaning.

[0049] In some embodiments, a second insulating protective layer (not shown in the figure) is provided between the seat body 100 and the silver paste heating layer 300. That is, the silver paste heating layer 300 is disposed between the first insulating protective layer 200 and the second insulating protective layer, and the first insulating protective layer 200 and the second insulating protective layer form a double insulating barrier to further reduce the risk of leakage.

[0050] Reference Figure 2 In some embodiments, the seat body 100 is provided with a terminal 400, an electrode wire 500, a sensing device 600, and a sensing wire 700. The terminal 400 is connected to the electrode wire 500 and the sensing wire 700, respectively. The electrode wire 500 is connected to the silver paste heating layer 300, and the sensing wire 700 is connected to the sensing device 600. By only providing the terminal 400, electrode wire 500, sensing device 600, and sensing wire 700 inside the seat body 100, the overall thickness of the toilet seat is reduced, simplifying the overall manufacturing process.

[0051] In some embodiments, the terminal 400 is used in connector accessories to realize electrical circuit connections. The terminal 400 is connected to the electrode wire 500, the sensing wire 700, and other circuit groups, and the terminal 400 is connected to the power supply group. Of course, the circuit groups can also be designed to connect to a suitable carrier to form the terminal 400, such as a plastic material carrier. In actual design, the structure of the terminal 400 can be designed according to actual needs.

[0052] In some embodiments, the electrode wire 500 material includes, but is not limited to, stainless steel wire, copper wire, silver wire, aluminum wire, nickel wire, tungsten wire, molybdenum wire, titanium wire, and alloy wires of metals. Alloy wires of metals include, but are not limited to, titanium-tungsten alloy wire, copper-aluminum alloy wire, copper-tungsten alloy wire, silver-tungsten alloy wire, and combined metal wires. Combined metal wires include, but are not limited to, steel-cored aluminum electrode wire. Furthermore, in addition to metal electrodes, carbon material electrodes (e.g., graphite, carbon fiber, carbon nanotubes, etc.), metal oxide electrodes (e.g., iridium oxide, tin oxide, etc.), and polymer electrodes (e.g., conductive polymers polyaniline, polypyrrole, etc.) can all be used as electrode wire 500 materials. Preferably, the electrode wire 500 material is a copper wire, silver wire, or nickel wire with high conductivity.

[0053] In some embodiments, the electrode line 500 includes a positive electrode line and a negative electrode line, both of which are connected to the power supply group and the silver paste heating layer, respectively. Specifically, the positive electrode line is connected to the positive terminal of the power supply group and the silver paste heating layer 300, and the negative electrode line is connected to the negative terminal of the power supply group and the silver paste heating layer 300, ensuring stable power input and establishing a complete current loop.

[0054] In some embodiments, the sensing device 600 is a temperature sensing device. Specifically, a temperature sensing device is a sensor capable of sensing temperature and converting it into a usable output signal. Based on the measurement method, it can be divided into two main categories: contact and non-contact. Based on the sensor material and electronic component characteristics, it can be divided into two categories: resistance temperature detectors (RTDs) and thermocouples. By installing a temperature sensing device, the toilet seat temperature can be precisely controlled, and the seat temperature can be monitored in real time. The data is fed back to the toilet control system, which adjusts the power of the heating element accordingly to maintain the toilet seat at a suitable temperature, providing a comfortable user experience. Simultaneously, the temperature sensing device also ensures that the temperature of all parts of the toilet seat is even, avoiding localized overheating or undercooling. When the heating element inside the toilet seat malfunctions, causing an abnormal temperature rise, the temperature sensing device can also quickly detect this and transmit the signal to the toilet control system. The toilet control system will automatically cut off the power to prevent fires or other safety accidents.

[0055] In some other embodiments, the sensing device 600 is a mechanical travel device. A mechanical travel device uses the collision of mechanical moving parts to actuate its contacts, thereby connecting or disconnecting the control circuit to achieve a certain control purpose. Furthermore, mechanical travel devices include, but are not limited to, pressure sensors and vibration sensors.

[0056] Reference Figure 2 In some embodiments, the seat body 100 is provided with an assembly interface 800, which is connected to the toilet. The terminal 400 is installed inside the assembly interface 800. The assembly interface 800 ensures the alignment of the seat body 100 with the toilet and avoids seat shaking or discomfort caused by installation deviation.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
