Abstract

The invention relates to an electric heating pad and a manufacturing method thereof. A conducting film with positive temperature coefficient is adhered to one surface of base material; then two conducting wires which are mutually staggered are printed on the conducting film; two conducting pads are respectively riveted on the conducting wires, the conducting film and the base material; the conducting material adopts a full pad type conducting film, and is directly adhered to a work piece or the flexible base material; then the conducting wires are printed on the conducting material; and conducting carbon is not required to be printed on the conducting material. The electric heating pad has the advantages that the production and manufacture are convenient, the electric heating pad can be rapidly heated up, and the temperature can be effectively maintained.

Description

technical field [0001] The invention relates to a structure and a manufacturing method of an electric heating sheet, which can be applied to heating elements such as rearview mirror defrosting, electric blankets, heat preservation pads, etc., to ensure effective temperature maintenance. Background technique [0002] With the improvement of living standards, various heating or thermal insulation elements or products have emerged as the times require, and are widely used in various products. It is often necessary to manually wipe its surface, causing inconvenience in driving; or, because the weather temperature is low, the insulation effect of the blanket is limited. [0003] In order to solve the above problems, heating elements such as electric heaters are installed on the back of the rearview mirror of the car to defrost, or heating elements are embedded in the blanket to improve the heat preservation effect. Its heating element is as disclosed in my country's new patent N...
