Problems solved by technology

The heating components of existing electric heating products are generally directly sewn or bonded to the base material by metal resistance sheets, which not only has poor heating effect, but also has poor flexibility and is not easy to bend. It is not suitable for bending with elbows, knees, necks, etc. At the same time, when the heating element fails, the electric heating product must be disassembled as a whole, which is very inconvenient for maintenance. Generally, it can only be scrapped, which greatly causes waste of materials

Abstract

The invention relates to the technical field of heating and provides an electric heating device. The electric heating device comprises two protection layers, two adhesive layers and a heating layer, wherein the heating layer is arranged between the two adhesive layers in a coated mode, forming a closed structure; a set of power supply connecting points are arranged on the opposite corners of the heating layer, comprise one positive pole connecting point and one negative pole connecting point and are connected with a power supply through guide lines separately; the two protection layers are arranged on the outer sides of the two adhesive layers separately, and the edge of the first protection layer and the edge of the second protection layer are adhered together to form a closed structure; the protection layers and the heating layer are made of flexible materials; the heating layer comprises carbon nanotube thin films and two electrode plates, and the two electrodes are not intersected and connected through at least one carbon nanotube thin film; the power supply connecting points are contact points of the guidelines and the electrode plates. The electric heating device is good in heating effect, good in flexibility, easy to bend, convenient to disassemble and assemble, and long in service life.

Description

technical field [0001] The invention relates to the technical field of heat generation, in particular to a heat generation layer. Background technique [0002] With the enhancement of people's health awareness, diversified human body electric heating and health care products such as clothing, protective gear, bedding, and electronic products emerge in an endless stream. The heating components of existing electric heating products are generally directly sewn or bonded to the base material by metal resistance sheets, which not only has poor heating effect, but also has poor flexibility and is not easy to bend. It is not suitable for bending with elbows, knees, necks, etc. At the same time, when the heating element fails, the electric heating product must be disassembled as a whole, which is very inconvenient for maintenance. Generally, it can only be scrapped, which greatly wastes materials. Contents of the invention [0003] The object of the present invention is to overco...
