Description

Technical Field

[0001] This utility model belongs to the field of graphene heating pad technology, specifically a graphene electrothermal film heating pad. Background Technology

[0002] Graphene is a two-dimensional periodic honeycomb lattice structure composed of six-membered carbon rings. It can be warped into zero-dimensional (0D) fullerenes, rolled into one-dimensional (1D) carbon nanotubes, or stacked into three-dimensional graphite. Therefore, graphene is the basic unit that constitutes other graphite materials. Graphene is a two-dimensional material composed of a single layer of carbon atoms with excellent thermal and electrical conductivity. This allows graphene to quickly and uniformly convert electrical energy into heat energy. Due to its extremely high thermal conductivity, graphene can be used to make graphene heating pads to provide heat to objects or users.

[0003] Graphene heating pads (flexible pads) typically consist of a graphene heating film, a felt pad or a flexible pad, and a heat insulation and protective pad.

[0004] In existing technologies, the flexible pad is usually placed on top of the graphene heating pad, which is in direct contact with the external environment. Over time, the flexible pad is prone to wear and tear, affecting its service life. In addition, the graphene heating pad has poor air permeability. Summary of the Invention

[0005] The purpose of this invention is to provide a graphene electric heating film heating pad that can shield and protect the internal structure of the protective pad, thus extending its service life. It also gives the pad good moisture absorption and breathability, prevents wear and tear on flexible pads caused by prolonged use, and improves the anti-slip performance of the protective pad.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a graphene electric heating film heating pad, comprising a protective pad, wherein a graphene heating film is disposed inside the protective pad, and a heat-conducting film layer and a heat-insulating pad are also disposed inside the protective pad on the upper and lower sides of the graphene heating film, and a power cord is connected to one side of the graphene heating film via a terminal block; a flexible pad is disposed on the upper surface of the heat-conducting film layer, and a wrapping pad is disposed above the protective pad, wherein a first Velcro fastener is disposed between the upper surface of the protective pad and the wrapping pad, and the wrapping pad comprises a breathable layer and a sweat-absorbing layer disposed on the upper surface of the flexible pad, wherein the breathable layer is disposed on the upper surface of the sweat-absorbing layer;

[0007] The bottom of the protective pad is provided with a bottom layer.

[0008] To facilitate the disassembly of the flexible pad and the thermally conductive film layer, in a preferred embodiment of the graphene electric heating film heating pad of this utility model, the thermally conductive film layer and the flexible pad are bonded together by a second Velcro fastener.

[0009] To improve aesthetics, in a preferred embodiment of the graphene electric heating film heating pad of this utility model, the side of the wrapping pad near the protective pad is fixedly connected to an extension edge for covering the first Velcro, and the extension edge is located outside the first Velcro.

[0010] To keep the present invention dry, the preferred embodiment of the graphene electric heating film heating pad of the present invention has a breathable layer made of cotton material and a sweat-absorbing layer made of pure cotton material.

[0011] To improve the anti-slip performance of the structure, the bottom layer of the graphene electric heating film heating pad of this utility model is preferably provided with raised dots on its bottom surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by placing a covering pad on top of the protective pad, can shield and protect the internal structure of the protective pad, extending its service life. Simultaneously, by incorporating a breathable layer and a sweat-absorbing layer, it provides excellent moisture absorption and breathability, keeping the user dry and improving comfort. Furthermore, the covering pad and protective pad can be disassembled for easy cleaning of the covering pad. It also prevents the flexible pad from directly contacting the outside, thus avoiding wear and tear from prolonged use and extending its service life.

[0014] By setting a bottom layer, the anti-slip performance of the protective pad is improved, preventing the pad from shifting during use. Attached Figure Description
