Abstract

The invention discloses a microporous ceramic heating device for an atomizer, which comprises a microporous ceramic substrate and a heating wire arranged on the microporous ceramic substrate. Wherein, the heating wire is a thin strip-shaped heating wire formed after thick film printing, sintering and molding, and then processing by mechanical cutting, chemical etching or laser lithography. The heating wires are evenly distributed on the heating surface of the ceramic substrate. The preparation process of the microporous ceramic heating device for the atomizer of the present invention includes the following steps: setting a microporous ceramic substrate, the microporous ceramic substrate having a heating surface, and performing thick film printing on the heating surface of the microporous ceramic substrate , drying, sintering treatment. Then, the sintered thick film printing part is processed by mechanical cutting, chemical etching or laser lithography to form thin strip heating wires with a predetermined shape.

Description

technical field

[0001] The invention relates to a microporous ceramic heating device for an atomizer, in particular to a microporous ceramic substrate heating device using a thick-film printed resistor as a heating material.

[0002] The present invention also relates to a preparation process of the above-mentioned microporous ceramic heating device. Background technique

[0003] In the field of electronic cigarette technology, the use of microporous ceramics as the oil-conducting medium has become the mainstream configuration. In the electronic cigarette atomizer that uses microporous ceramics as the oil-conducting medium, it is necessary to make the resistance wire as close as possible to the electronic cigarette liquid in the microporous ceramics. Although the resistance wire away from the e-liquid will also generate heat, when the microporous ceramic is used as the oil-conducting component, the precipitated e-liquid cannot be separated from the surface of the micro-poro...
