Description

Technical Field

[0001] This utility model relates to an electric heating pad, specifically a multifunctional far-infrared electric heating pad. Background Technology

[0002] Chinese Patent Publication No. CN202121410484.9 discloses an infrared electric heating pad, comprising: a surface layer, a middle layer, an inner layer, and heating wires. The surface layer is in contact with the user, the inner layer is away from the user, and the middle layer is located between the surface and inner layers. The surface layer is made of infrared fabric, and the heating wires are fixed to the middle layer. Because the infrared fabric, which is in contact with the user, is located on the side closest to the user, and the heating wires are fixed in the middle layer, the infrared fabric and heating wires work together to better exert the therapeutic effect of infrared radiation, which is beneficial to human health. The infrared fabric being located on the side closest to the user allows for better penetration and therapeutic effects. However, this design uses heating wires, which has drawbacks such as uneven heating and large temperature differences during operation.

[0003] Chinese Patent Publication No. CN202120148748.1 discloses an electric heating pad with accurate temperature control, comprising a heating film with a heating circuit and a control board electrically connected to the heating circuit. The key feature is that the control board has a temperature sensing element, and the outer surface of the heating film has a metallic ink layer. The temperature sensing surface of the temperature sensing element contacts the metallic ink layer for temperature sensing. This invention, by setting a metallic ink layer on the outer surface of the heating film, ensuring close contact between the metallic ink layer and the heating film, and by having the temperature sensing surface of the temperature sensing element contact the metallic ink layer for temperature sensing, allows the heat from the heating film during operation to be transferred to the temperature sensing surface of the temperature sensing element through the metallic ink layer, resulting in very little heat loss and highly accurate temperature sensing by the temperature sensing element, thus achieving accurate temperature control of the electric heating pad. However, this solution uses a metallic ink layer as the heating element, but the metallic ink layer is printed using a printing process. Over prolonged use, issues such as ink delamination may occur, posing a safety hazard.

[0004] Chinese Patent Publication No. 202022914684.X discloses a novel seamless, heat-pressed, integrated foot-warming electric heating pad.

The inner side of the Ballis floor covering is fixedly connected to the outer side of the heating film, the inner side of the heating film is fixedly connected to the outer side of the reflective film, the inner side of the reflective film is fixedly connected to the outer side of the insulation film, and the inner side of the insulation film is fixedly connected to the outer side of the bottom surface. The surface is made of PVC floor covering. PVC decomposes under long-term exposure to far-infrared temperatures of 40-55 degrees Celsius, resulting in a limited lifespan.

[0005] The main purpose of this utility model is to address the above-mentioned problems and limitations by providing a multifunctional far-infrared electric heating pad. Its entire surface is a heating surface, the heating temperature is uniform, the service life can reach up to 100,000 hours, it has good waterproof effect, a wide range of applications, is easy to carry, warm and comfortable, and energy-saving.

[0030] The upper insulating protective layer 31 and the lower insulating protective layer 33 are made of polyester film with PE, EVA, or polyurethane backing, wherein the polyester film is one of PET, PE, or HDPE.
