Description

Technical Field

[0001] The present application relates to the technical field of heating pads, and in particular to a foot heating massage pad. Background Art

[0002] Heating foot pads are popular among consumers for their ability to replenish foot temperature, activate acupuncture points and meridians on the soles of the feet, promote blood circulation, and relieve fatigue. Existing heating foot pads typically use heating elements such as heating wires and heating tubes. Their working principle is that current passes through the wire, converting electrical energy into heat to replenish foot temperature.

[0003] Existing heating mats that use heating wires, heating tubes, and other heat sources as heating elements can generate electromagnetic radiation hazards during use. Using polymer heating films as heating elements can reduce these electromagnetic radiation hazards, but the film thickness significantly affects heating uniformity and the production process is demanding. This results in high costs for these heating mats, making them unacceptable to consumers.

[0004] In addition, the polymer electric heating film used as a heating device for heating pads also has the problem of low bending life. Limited by the influence of the polymer electric heating film substrate, the stress and strain at the bending force point during the winding and bending process of the polymer electric heating film is quite large. Furthermore, due to the influence of long-term cyclic heating, the molecular chain structure of the winding and bending process is irreversibly broken, resulting in problems such as crystallization and silver streaks, which in turn affects the surface resistance uniformity and surface resistance of the polymer electric heating film, resulting in the heating power of the heating pad attenuation and the decrease in heating uniformity. The overall service life of the heating pad product is relatively short. Utility Model Content

DETAILED DESCRIPTION

[0037] The present application is further described in detail below with reference to the accompanying drawings and examples. Example

[0038] Example 1, with reference to Figure 1A foot heating massage pad includes a floor covering 1, a self-limiting temperature heating component 2, an anti-slip mat 3, a reflective layer 4, a coupler 5, and a power connector 6. The self-limiting temperature heating component 2 is fixedly connected between the floor covering 1 and the anti-slip mat 3. The reflective layer 4 is fixedly connected between the self-limiting temperature heating component 2 and the anti-slip mat 3. Specifically, the reflective layer 4 is fixedly connected to the inner surface of the anti-slip mat 3 facing the self-limiting temperature heating component 2. The reflective layer 4 is composed of aluminum foil and TPU film, and the TPU film is fixedly connected to the inner surface of the anti-slip mat 3 by hot pressing. The aluminum foil in the reflective layer 4 reflects the infrared and far-infrared rays released by the self-limiting temperature heating component 2 toward the surface of the floor covering 1, thereby enhancing the heating performance of the infrared and far-infrared rays.

[0039] Reference Figure 1 The self-limiting temperature heating component 2 includes a non-woven fabric insulation layer 21 and a self-limiting temperature heating cloth 22, and the non-woven fabric insulation layer 21 is compounded on the upper and lower surfaces of the self-limiting temperature heating cloth 22. A conductive staple non-woven fabric layer 23 is hot-pressed and fixedly connected to the non-woven fabric insulation layer 21. The conductive staple non-woven fabric layer 23 is a graphene non-woven fabric made of graphene staple fibers, and the graphene non-woven fabric is provided with through holes 231 distributed in a dot matrix. The aperture of the through hole 231 is 0.5-2.0 mm, preferably 1 mm, and the distance between adjacent through holes 231 is 1.0-1.2 mm. The conductive staple non-woven fabric layer 23 with through holes 231 distributed in a dot matrix effectively weakens the hazards of electromagnetic radiation, while ensuring a stable release of infrared and far-infrared rays, giving it a good heating and warming effect on the feet and less irritation to the skin of the feet, thereby enhancing the market competitiveness of the product.
