Carbon crystal electric warming mat

Abstract

The invention discloses a carbon crystal electric warming mat which comprises a five-layer structure. An anti-sliding layer and one face of a PTC constant temperature two-sided heating layer are glued through a first gluing layer, the other face of the PTC constant temperature two-sided heating layer and a decoration layer are glued through a second gluing layer, an electrode is arranged in the PTC constant temperature two-sided heating layer, a control switch is arranged on the carbon crystal electric warming mat, and the control switch is connected with the electrode of the PTC constant temperature two-sided heating layer. By means of the mode, the shortcomings that a safe voltage lower than 36V cannot be used in a common carbon crystal electric warming mat, and gear control at the high temperature and the low temperature cannot be achieved under the condition that a 36V safe voltage is used are overcome, and the energy consumption is low; risks, such as temperature gathering, fire catching and radiation, of the common carbon crystal electric warming mat after long-time use are overcome, and the mouth parched and tongue scorched discomfort symptoms and the like of people after long-time use are avoided.

Description

technical field [0001] The invention relates to an electric heating device, in particular to a carbon crystal electric heating pad which is used for laying the ground of homes and workplaces and has a heating function. Background technique [0002] With the development of society, people's living standards have been greatly improved. In the cold winter, many families are no longer satisfied with the heating mode of the air conditioner, but are pursuing a healthier and more convenient heating method. The electric heating pad is favored by users because of its flexible and convenient use, safe and reliable laying. However, the electric heating pads in the prior art generally use ordinary metal resistance wires or carbon fibers as heating elements to make electric heating pads, and there are also two parallel electrodes made on polyester films, and parallel, regular ordinary carbon electrodes are printed. The slurry wire connects two electrodes as a heating element, and final...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the above-mentioned prior art, the main purpose of the present invention is to provide a carbon crystal electric heating pad, which solves the problem that ordinary electric heating pads cannot use a safe voltage below 36V and that when using a safe voltage of 36V, It can't reach the high and low temperature gear control and other deficiencies, and the energy consumption is low; it also overcomes the dangers of heat accumulation, fire, radiation, etc. after long-term use of ordinary electric heating pads; people will not feel discomfort such as dry mouth and tongue after long-term use symptom
