Problems solved by technology

[0002] At present, the office electric heating devices on the market are mainly glass electric heating plates. Because glass has strong thermal conductivity, the human body will feel icy cold after touching it at room temperature.
Moreover, because the common electric heating plate uses glass as the panel, it is not only bulky, but also very inconvenient to transport.

Abstract

The invention relates to the production field of electric heating pads, in particular to an electric heating wiring pad. The electric heating wiring pad comprises an anti-sliding rubber layer, a foaming sponge layer and a PU layer. The PU layer is arranged on the upper surface of the foaming sponge layer, and the anti-sliding rubber layer is arranged on the lower surface of the foaming sponge layer; a wire arrangement groove is formed in the foaming sponge layer, and a heating wire is arranged in the wire arrangement groove; and the end of the heating wire is connected with a controller and a plug through a wire. According to the electric heating wiring pad and a production method of the pad, the electric heating wiring pad is better in integrality, smooth and flat in surface, excellent in using comfort, longer in service life and safer in using process, and the high temperature resistance of the surface is better.

Description

technical field [0001] The invention relates to the field of electric heating pad production, in particular to an electric heating writing pad and a production method thereof. Background technique [0002] At present, the office electric heating devices on the market are mainly glass electric heating plates. Because glass has strong thermal conductivity, the human body will feel icy cold after touching it at room temperature. Moreover, because the common electric heating plate uses glass as the panel, it is not only bulky, but also very inconvenient to transport. At the same time, its heat conduction effect and warmth retention effect are also very general. Contents of the invention [0003] The object of the present invention is to provide an electric heating writing pad with comfortable hand feeling and high safety in use and a production method thereof in order to solve the deficiencies of the above-mentioned technologies. [0004] In order to achieve the above object...
