Description

Technical Field

[0001] This application relates to the field of toilet seats, and more specifically, to an instant-heating toilet seat and toilet. Background Technology

[0002] Traditional heated toilet seats include a seat ring, seat liner, heating element, and electrical components such as a temperature sensor. The heating element is bonded to the bottom of the seat ring, and the electrical components such as the temperature sensor are fixed to the surface of the heating element and welded to it. The seat ring and seat liner are welded together. Both the seat ring and seat liner are single plastic components, and the heating element includes a heating wire or heating plate.

[0003] The heating function of the toilet seat is achieved by attaching a heating element to the bottom of the seat ring. However, because the heat from the heating element needs to pass through the entire seat ring to be reflected on the surface of the seat ring, the existing toilet seats have problems such as slow heating speed, high energy consumption and low safety. Utility Model Content

[0004] The purpose of this application is to provide an instant-heating toilet seat and toilet to alleviate the technical problems of slow heating speed, high energy consumption and low safety of toilet seats in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] Firstly, the instant heating seat ring provided by this utility model includes a seat ring body and a heating layer;

[0007] The seat ring body has an upper surface, and the heating layer covers the upper surface of the seat ring body and is integrally formed with the seat ring body;

[0008] The heating layer includes a heating diaphragm having heating lines that extend along the circumference of the seat body.

[0009] Furthermore, the heating lines are evenly arranged along the circumference of the seat body.

[0010] Furthermore, the heating layer also includes a composite diaphragm, which is bonded to the heating diaphragm and is located between the composite diaphragm and the seat ring body.

[0011] Furthermore, the composite diaphragm has a first decorative area on the surface opposite to the heating diaphragm.

[0012] Furthermore, the composite membrane includes a base film and a surface film, the base film and the surface film are bonded together, and the base film is located between the surface film and the heating membrane.

[0013] Furthermore, the instant-heating seat also includes a seating sensing structure located above the seat body.

[0014] Furthermore, the seat sensing structure includes a seat sensing circuit located within the heating diaphragm and extending along the circumference of the seat body.

[0015] Furthermore, the seat sensing circuit surrounds the outer periphery of the heating circuit and extends around the circumference of the seat body.

[0016] Furthermore, the instant heating seat also includes a coating that covers the surface of the composite diaphragm opposite to the heating diaphragm, and the surface of the coating opposite to the composite diaphragm has a second finishing area.

[0017] Secondly, the toilet provided by this utility model includes an instant-heating seat ring as described in any of the above claims.

[0018] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0019] The instant-heating seat ring provided by this utility model includes a seat ring body and a heating layer; the seat ring body has an upper surface, and the heating layer covers the upper surface of the seat ring body and is integrally formed with the seat ring body; the heating layer includes a heating diaphragm, the heating diaphragm has heating lines, and the heating lines extend along the circumferential direction of the seat ring body.

[0020] A heating layer covers the upper surface of the seat ring body and includes a heating diaphragm with heating circuitry. The heating diaphragm is heated via these circuits. This allows the heating layer to be positioned above the seat ring body, eliminating the need for heat to penetrate the seat ring body, thus achieving rapid heating, improving heating efficiency, reducing energy consumption, and enhancing safety. Furthermore, because this instant-heating seat ring heats up quickly, heating is completed from the moment you enter the bathroom until you begin using it, eliminating the need for prolonged waiting or continuous power supply. Not requiring prolonged power also avoids the problem of bacterial growth.

[0021] The heating layer and the seat ring body are integrally molded, eliminating the need for secondary welding, improving production efficiency, and avoiding the problem of dirt accumulating at the weld seam during secondary welding. Attached Figure Description

[0033] Example 1

[0034] Traditional heated toilet seats typically consist of two separate plastic pieces, the seat ring and the seat liner, welded together to form a single, commercially available toilet seat. The heating function of current toilet seats mainly uses heating wires or heating elements, which are attached to the bottom of the seat ring with adhesive thermal grease. Electrical components, such as temperature sensors, are then fixed to the heating element surface with screws. The entire assembly is then sealed to the seat liner through friction welding to form the finished product. While attaching the heating element to the bottom of the seat ring achieves the heating function, the heat from the heating wire needs to penetrate the entire seat ring to reach the surface, resulting in slow heating speed, high energy consumption, and insufficient safety. Furthermore, the surface material of traditional toilet seats is mostly ordinary polypropylene plastic, which lacks antibacterial, stain-resistant, and scratch-resistant properties, and its limited appearance fails to meet users' demands for comfort and aesthetics.

[0035] In view of this, see Figure 1 The instant-heating seat ring provided in this embodiment of the utility model includes a seat ring body 100 and a heating layer 200; the seat ring body 100 has an upper surface, and the heating layer 200 covers the upper surface of the seat ring body 100 and is integrally formed with the seat ring body 100; the heating layer 200 includes a heating diaphragm 210, the heating diaphragm 210 has a heating line 211, and the heating line 211 extends along the circumferential direction of the seat ring body 100.

[0036] Specifically, the seat ring body 100 can be configured as U-shaped, O-shaped, or figure-eight shaped, etc., without limitation; the upper surface of the seat ring body 100 and the side wall adopt a smooth arc transition to avoid the problem of stress concentration at sharp corners and easy breakage; the side wall of the seat ring body 100 can also be covered with a heating layer 200 to increase the area of ​​the heating layer 200 and thus improve heating efficiency. Furthermore, the seat ring body 100 and the heating layer 200 are integrally injection molded.

[0037] A heating layer 200 covers the upper surface of the seat ring body 100 and includes a heating diaphragm 210 with heating circuits 211. The heating diaphragm 210 is heated by the heating circuits 211. This allows the heating layer 200 to be positioned above the seat ring body 100, eliminating the need for the heating circuits 211 to pass through the seat ring body 100, thus achieving rapid heating, improving heating efficiency, reducing energy consumption, and enhancing safety. Furthermore, because this instant-heating seat ring heats up quickly, heating is completed from the moment the user enters the bathroom until use, eliminating the need for prolonged waiting or continuous power supply. The absence of prolonged power supply also prevents bacterial growth. The heating layer 200 is integrally formed with the seat ring body 100, eliminating the need for secondary welding, improving production efficiency, and avoiding the problem of contamination at weld seams during secondary welding. This instant-heating seat ring achieves rapid heating, energy saving, and environmental protection while ensuring safety, and also offers diverse design options and excellent surface performance.

[0038] The structure and shape of the instant-heating seat ring are described in detail below:

[0039] In the optional solution provided by this utility model embodiment, the heating line 211 is evenly arranged along the circumferential direction of the seat ring body 100.

[0040] Specifically, in existing technologies, the heating coils of the seat ring are unevenly distributed, failing to heat the seat ring surface uniformly. In this embodiment, the entire upper surface of the seat ring body 100 is covered with a heating layer 200, and the heating lines 211 within the heating layer 200 are evenly arranged, enabling the entire upper surface of the seat ring body 100 to be heated. Furthermore, in this embodiment, the heating diaphragm 210 is produced using an etching process, through precise printing, to ensure the uniform distribution of the heating lines 211.

[0041] The heating circuits 211 are evenly arranged to achieve uniform heating of the upper surface of the seat ring body 100.

[0042] As a method of uniformly arranging heating circuits 211: see Figure 2 The heating line 211 zigzags back and forth and extends along the circumference of the seat body 100.

[0043] As another way to uniformly arrange the heating lines 211: see [link / reference] Figure 3 The heating circuit 211 is in the shape of a ring and is wound in a bidirectional alternating manner along the circumference of the seat ring body 100, with adjacent coils rotating in opposite directions.

[0044] In the optional embodiment of this utility model, the heating layer 200 further includes a composite diaphragm 220, which is bonded to the heating diaphragm 210, and the heating diaphragm 210 is located between the composite diaphragm 220 and the seat ring body 100.

[0045] Specifically, the heating film 210 is a metal film. After the metal film and the composite film 220 are bonded together, heating lines 211 are printed and etched to form a heating layer 200. Furthermore, the heating film 210 and the composite film 220 are bonded together by a first adhesive layer 230.

[0046] The composite diaphragm 220 serves to support and protect the heating diaphragm 210.

[0047] In the optional embodiment of this utility model, the surface of the composite diaphragm 220 facing away from the heating diaphragm 210 has a first decorative area.

[0048] Specifically, the composite diaphragm 220 can be made of the following materials: PP (polypropylene), PVC (polyvinyl chloride), or PETG (polyethylene terephthalate-1,4-cyclohexanediol). The first decorative area refers to the area with color or pattern; multiple first decorative areas can be provided, arranged in different ways, such as alternating or staggered arrangements, to form instant heating seat rings with different appearances; alternatively, the first decorative area can be laid flat on the entire upper surface of the composite diaphragm 220. The specific pattern and arrangement of the first decorative areas can be designed according to customer requirements.

[0049] The composite diaphragm 220 has a first decorative area, which enables the seat ring to be decorated.

[0050] In the optional embodiment of this utility model, the composite film 220 includes a base film 221 and a face film 222, the base film 221 and the face film 222 are bonded together, and the base film 221 is located between the face film 222 and the heating film 210.

[0051] Specifically, both the base film 221 and the face film 222 are layered, and the base film 221 and the face film 222 are bonded together by a second adhesive layer 240.

[0052] The base film 221 and the face film 222 form a composite film 220, which improves the strength of the composite film 220.

[0053] In the optional solution provided by this utility model embodiment, the instant-heating seat ring also includes a seating sensing structure, which is located above the seat ring body 100.

[0054] Specifically, the instant-heating seat ring also includes a controller, which can be installed according to actual needs; the controller is connected to the seat sensing structure and the heating circuit 211; the controller can control the on / off of the heating circuit 211; the seat sensing structure can transmit information about whether the seat ring body 100 is in use to the controller, and the controller controls the opening and closing of the seat cover.

[0055] The seat sensing structure is used to sense whether the seat body 100 is in use. When the seat body 100 is in use, the controller controls the seat cover to remain open.

[0056] In the optional solution provided by this utility model embodiment, the seat sensing structure includes a seat sensing line 212, which is located inside the heating diaphragm 210 and extends along the circumferential direction of the seat body 100.

[0057] Specifically, the seating sensing circuit 212 and the heating circuit 211 are processed simultaneously to improve production efficiency. The seating status is determined by detecting the capacitance change of the seating sensing circuit 212 caused by the approach of a human body; this achieves non-contact detection and avoids mechanical wear.

[0058] In the optional solution provided by this utility model embodiment, the seat sensing line 212 is arranged around the outer periphery of the heating line 211 and extends around the circumference of the seat body 100.

[0059] Specifically, existing seat sensors are arranged at single or multiple points, which cannot meet the needs of different usage scenarios. For example, when using the toilet for a long time, the user's movement may accidentally trigger the seat sensor, causing the seat cover to close and hit the user. When children or toddlers use the toilet, they can only touch the front half of the seat, and the single or multiple seat sensors cannot detect this, causing the seat cover to close and hit the user. The seat sensing circuit 212 is arranged around the heating circuit 211 and extends around the circumference of the seat body 100, so that the seat sensing circuit 212 is evenly distributed and fully covered around the entire seat body 100, solving the problems of compatibility and prevention of accidental triggering for multiple usage scenarios and multiple users.

[0060] In the optional embodiment of this utility model, the instant heating seat ring further includes a coating 300, which covers the surface of the composite diaphragm 220 away from the heating diaphragm 210.

[0061] Specifically, coating 300 can be made of the following materials: PP, PVC, or PETG. Furthermore, in this embodiment, coating 300 is applied to the surface of heating layer 200 using a TOM (Three Dimension Overlay Method) process. The surface of coating 300 is resistant to scratches of 4H hardness and is stain-resistant (e.g., using a Deli 6824 oil-based pen).

[0062] Coating 300 improves the stain and scratch resistance of the seat body 100.

[0063] In the optional embodiment of this utility model, the coating 300 has a second decorative area on the surface opposite to the composite film 220.

[0064] Specifically, the second finish area refers to an area with color or pattern; multiple second finish areas can be provided, arranged in different ways, such as alternating or staggered arrangements, to form instant-heating seat rings with different appearances; or, the second finish area can be laid flat on the entire upper surface of the coating 300. The specific pattern and arrangement of the second finish area can be designed according to customer requirements. It is worth noting that if the instant-heating seat ring includes a coating 300 with second finish areas, the composite diaphragm 220 may not have a first finish area, avoiding the problem of the second finish area obscuring the first finish area and thus wasting costs.

[0065] The coating 300 has a second finish area, which allows for the appearance decoration of the seat ring.

[0066] In the optional solution provided by this utility model embodiment, the instant heating seat ring also includes a temperature sensor, which is installed inside the seat ring body 100 and is mechanically fixed.

[0067] Specifically, when the seat ring body 100 is injection molded using a mold, a position is reserved on the mold so that the temperature sensor can be installed inside the seat ring body 100 and fixed with screws. The temperature sensor is connected to the controller signal and can transmit the detected temperature information to the controller, which controls the on / off state of the heating circuit 211 based on the temperature information.

[0068] A temperature sensor is used to detect the temperature near the seat body 100 and control the on / off of the heating circuit 211 according to the actual temperature, so that the temperature of the instant heating seat is more suitable for the human body.

[0069] The following describes the production process of heating layer 200:

[0070] The base film 221 and the face film 222 are bonded together to form a composite film 220;

[0071] The composite diaphragm 220 is bonded to the metal heating diaphragm 210 to form a composite polymer diaphragm with heating diaphragm 210;

[0072] Printed heating circuit 211 forms a metal composite polymer film with circuitry;

[0073] Etching the heating lines 211 forms a heating layer 200 with complete heating lines 211.

[0074] The following describes the production process of integrally molding the heating layer 200 and the seat ring body 100:

[0075] A heating layer 200 with complete heating circuitry 211 is formed by in-mold injection molding to create a seat ring body 100 with heating function;

[0076] The coating 300 is then processed using the TOM process to form an instant-heating seat ring.
