Heating body and production process

Abstract

The invention discloses a heating body and a production process, the heating body comprises a high-porosity ceramic body and a low-porosity ceramic body, the high-porosity ceramic body is embedded ina cavity of the low-porosity ceramic body, the outer side surface of the high-porosity ceramic body is printed with a heating circuit, and the heating circuit is connected with a lead. The process forproducing the heating body comprises the following steps: forming a low-porosity ceramic body penetrating through a cavity, forming a high-porosity ceramic body in the cavity of the low-porosity ceramic body to obtain a composite base, embedding the composite base into ceramic powder, discharging the forming agent in the composite base in a glue discharging furnace, sintering the high-porosity ceramic body and the low-porosity ceramic body into a whole, printing the heating circuit on the outer surface of the high-porosity ceramic body, and welding the lead to an electrode of the heating circuit. The method has the advantages that the problem of low strength caused by high porosity is solved, the purpose of high porosity and high strength is achieved, the structural strength is met underthe condition that the ideal atomization taste effect is guaranteed, and the problem of fragmentation is solved.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to a heating body and a production process. Background technique [0002] At present, the thick-film printed microporous ceramic atomizing core of the electronic cigarette is formed by printing a thick-film heating circuit on the microporous ceramic base and co-firing at high temperature. The ceramic base is formed by a single formula, and the microporous ceramic base is made of a higher The porosity is made. In the case of high porosity, the strength of the microporous ceramic base is relatively low, and it is easy to break, resulting in poor assembly and quality risks. Microporous ceramics with low porosity have high strength, but the atomization effect is not good, the liquid conduction is slow and it is easy to dry, which affects the taste. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a heati...
