Graphene electric heating piece and manufacturing process and application thereof

Abstract

The invention provides a combustion-free roasting device made of a graphene electric heating piece. The graphene electric heating piece comprises a positive electrode conductive gate, a negative electrode conductive gate and a graphene electric heating coating, wherein the positive electrode conductive gate and the negative electrode conductive gate are connected through the graphene electric heating coating. The graphene electric heating coating forms a conductive network with invariable resistivity and emits heat when being electrified. The resistance value of the graphene electric heating coating is relatively low, so that the graphene electric heating coating is high in heating power, low in power consumption and long in service life under a constant-voltage condition. The manufacturedcombustion-free roasting device is large in heating area, small in power consumption, long in service life, environmentally friendly, capable of better meeting the use requirements of smokers, more beneficial to abandoning traditional smoking habits of the smokers and capable of reducing public health hazards caused by smoking of the smokers.

Description

technical field [0001] The invention relates to the technical field of reducing environmental pollution, in particular to a graphene electric heating element, its manufacturing process and its application. Background technique [0002] Smoking is harmful to health, but it is difficult for smokers to quit, so smokers are still everywhere. In traditional smoking, tobacco burns to produce a large number of smoke particles, causing serious environmental pollution, causing others to smoke passively and endangering public health. In the absence of universal smoking ban, the only way to reduce the public health hazards caused by smokers is to change the way of smoking. [0003] A class of non-combustion smoking products that use electric energy to generate heat has appeared in the market. This type of product evaporates the volatile substances or flavor substances in the cigarettes by heating the cigarettes, so as to meet the needs of smokers without burning cigarettes and avoid ...

AI Technical Summary

Problems solved by technology

The carbon rod heating scheme needs to ignite and ignite the carbon rod operation, which is a one-time fast-consumable item, which will bring a lot of waste; the resistance wire heating scheme, the heating area of ​​the resistance wire is small, and the direct use of the resistance wire as a broiler will cause heat generation. The area is too small to roast a large area of ​​non-combustible smoking cigarettes, that is, it cannot meet the requirements of smokers; in order to make the resistance wire heating scheme meet user requirements, the roasting surface of the roaster is increased through secondary conduction, but in this way It will cause the product to require a battery with a larger storage capacity, and the greater the storage capacity of the battery, the greater the cost of the battery, and the increase in product volume. While increasing the cost of the product, it will also bring inconvenience to smokers. Make smokers more inclined to use traditional smoking methods, which is not conducive to achieving the purpose of changing smokers' smoking habits
