Electronic cigarette atomization core and preparation method thereof

Abstract

The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette atomization core and a preparation method thereof. The electronic cigarette atomizationcore comprises a heating body and a tar storage body connected with the heating body; the heating body comprises a first ceramic block and a heating mesh embedded in the first ceramic block; the heating mesh comprises electrodes, a heating wire assembly connected between the electrodes and fixing pins. The depth of the electrodes and the heating wire assembly embedded in the first ceramic block is0.5-1 time of the thickness of the heating mesh; the depth of the fixing pins embedded in the first ceramic block is 0-1 time of the thickness of the first ceramic block, and the included angle between the fixing pins and the heating wire assembly is 0-180 degrees. By means of the mode, the heating mesh is not prone to being separated from the first ceramic block when heated, the requirement formaterial selection of the heating mesh and the first ceramic block is lowered, meanwhile, the requirement for the preparation process of the heating body is lowered, and the production yield is increased.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette core and a preparation method thereof. Background technique [0002] The ceramic heating body is a safe and reliable electric heating element that generates heat without being charged and has no open flame after being energized. The main form of the current ceramic heating element is to print electronic paste on the ceramic, bake it at high temperature and then process the electrode and lead wire to produce the heating element. However, the heating element of the printed heating circuit generally has technical defects such as slow heating speed, uneven temperature distribution, easy breakage of the heating circuit, warping deformation or even cracking of the ceramic sheet, poor user experience, and short service life.

Problems solved by technology

However, the heating element of the printed heating circuit generally has technical defects such as slow heating speed, uneven temperature distribution, easy breakage of the heating circuit, warping deformation or even cracking of the ceramic sheet, poor use experience, and short service life.

[0003] At present, some heating elements are inlaid with stainless steel heating mesh on the surface of ceramics. Although it can solve the problems of slow heating speed, uneven temperature distribution, easy breakage of heating lines, warping deformation and even cracking of ceramic sheets, etc., but The thermal expansion of the heating mesh is generally larger than that of ceramics, and there are strict requirements for the selection of materials for the heating mesh and ceramics. During molding and sintering, the heating mesh is easy to separate from the ceramic body. The heating mesh is separated from the ceramic body, causing dry burning, or even burning out the atomizing core components
