Planar metal low-temperature heating device and fabrication process

Abstract

The invention discloses a planar metal low-temperature heating device and a fabrication process, and relates to the technical field of low-temperature heating cigarette. The planar metal low-temperature heating device comprises an external protection enamel layer, a metal support sheet layer, an insulation dielectric layer, a support layer and a metal heating track layer, wherein the insulation dielectric layer is coated on an outer surface of the metal support sheet layer, the metal heating track layer is embedded into the support layer, the metal heating track layer and the support layer form a filling layer, the filling layer is attached onto an upper surface of the insulation dielectric layer, the filling layer and the insulation dielectric layer are wrapped by the external protectionenamel, two ends of the metal heating track layer extends out of the external protection enamel layer, and the two ends of the metal heating track layer are respectively connected with a positive electrode and a negative electrode of a power supply. The planar metal low-temperature heating device has the beneficial effects that a metal material is used as a support body, the planar metal low-temperature heating device is good in flexibility, and the problem of circuit breakage caused by slight bending is prevented.

Description

technical field [0001] The invention relates to the technical field of low-temperature heating cigarettes, and more specifically, the invention relates to a flat metal low-temperature heating device and a manufacturing process. Background technique [0002] Traditional tobacco is smoked by burning. When the tobacco is burned, it will produce tobacco-flavored smoke containing nicotine to meet the needs of smokers. At the same time, the released smoke also contains more than 3,800 known chemical substances, most of which are harmful to the human body. , including carbon monoxide, amines, nitriles, drunks, phenols, alkanes, aldehydes, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, hydroxyl compounds, heavy metal elements, organic pesticides, etc., a wide range, they There are a variety of biological effects, causing various hazards to the human body. And the smoke from burning tobacco will enter the environment to produce second-hand smoke, which wi...

Problems solved by technology

[0004] At present, the internal heating structure of this kind of electronic cigarette products generally uses ceramic sheets as the support body. The ceramic sheet has the problem of poor toughness. Bending under force may easily cause the ceramic sheet to break, resulting in a short circuit of the heating circuit, resulting in damage to the product. question
