Abstract

The invention discloses an electronic cigarette film heating sheet, which comprises a ceramic bare chip made of zirconia or alumina, wherein a heating resistance film layer is plated outside the ceramic bare chip by a vapor deposition technology, the thickness of the heating resistance film layer is less than 2 mu m, and a three-protection protective film layer is plated outside the heating resistance film layer by the vapor deposition technology; with the vapor deposition technology applied to the heating resistance film layer of the electronic cigarette heating sheet, +/-1% resistance precision of the heating resistance film layer is realized, the circuit design difficulty of the electronic cigarette appliance is reduced, meanwhile, the surface coverage of the heating circuit pattern isrealized with the effective coverage area of the heating contact part of the electronic cigarette being more than or equal to 95%, the even heat and temperature of the whole heating layer are realized, and the smoking taste of the electronic cigarette is improved; with the application of the vapor deposition technology to the three-protection protective film layer of the electronic cigarette heating sheet, the protective layer can prevent the resistance from oxidation, has high temperature resistance and good heat conduction effect, improves the oleophobic and hydrophobic functions of the heating sheet, and achieves the self-cleaning effect of the heating sheet.

Description

technical field [0001] The invention relates to the field of low-power heating devices, in particular to an electronic cigarette film heating sheet. Background technique [0002] E-cigarettes are electronic products that mimic cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that allows users to smoke nicotine by means of heat-not-burn, atomization, etc., so that the specially-made pods and e-liquid can volatilize nicotine and reduce the harm of cigarettes. [0003] At present, the heating technologies of e-cigarettes on the market mainly include central heating sheet technology, central heating needle technology and peripheral heating cup technology. [0004] Advantages of central heating sheet technology: sheet structure, fast heating speed, can get any temperature distribution; high reliability, heating element material will not oxidize, excellent acid and alkali resistance; corrosion resistance, high temperature resistance, relativ...
