Heating device of electronic cigarette

Abstract

The invention discloses a heating device of an electronic cigarette, which comprises a base body, a heating unit and a conductive unit, the heating unit and the conductive unit are fixed on the outersurface of the base body, and the base body, the heating unit, the conductive unit and a power supply are electrically conducted to form a loop. The base body is used as an electric conductor to be connected with one end of the heating unit, the electric conductor is connected with the other end of the heating unit to form a loop, the heating unit can be arranged to be in a sheet shape, generatedheat is more uniform, a tobacco product can be heated more uniformly, and the situation that a high-temperature place is burnt, and a low-temperature place generates insufficient smoke or does not generate smoke is avoided.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a heating device for electronic cigarettes. Background technique [0002] When a cigarette is burned, it produces harmful gases such as carbon monoxide. With the development of science and technology, heat-not-burn electronic cigarettes have appeared, that is, the method of baking is used to make the smoke products emit smoke for people to smoke. [0003] In order to form a conductive circuit for the printed circuit on the existing heating needle, the printed circuit must be in the shape of a line (such as figure 1 ), can not be set into a sheet, so that on the one hand, the effective heating area of ​​the printed circuit is greatly reduced, on the other hand, the temperature of the place where the heating needle has a printed circuit is high, and it is easy to burn the smoked products; the temperature of the place where the heating needle is not printed circuit is low , Th...

AI Technical Summary

Problems solved by technology

The second heating circuit b should reserve a certain wiring space c, and for the heating needle to be easily inserted into the smoking product (the cross-sectional size of the heating tube needs to match the cross-section of the smoking product), the heating needle (or heating tube) The size is strictly limited and cannot be increased arbitrarily, so the second heating circuit b can only be narrowed. On the one hand, because the second heating circuit b needs to form a loop with the power supply, the second heating circuit b is too narrow to be printed. resulting in low yield; on the other hand, there is no heating circuit at the reserved wiring space c, so that the smoking products here cannot be heated well
