Electronic cigarette, sheet heating body of electronic cigarette and preparation method of sheet heating body

Abstract

The invention discloses an electronic cigarette, a sheet heating body of the electronic cigarette and a preparation method of the sheet heating body. The preparation method comprises the steps that ceramic slurry is prepared and subjected to casting to form a plurality of membranes; a part of the membranes are punched; electrodes are printed on first sides of the punched membranes; heating circuits and temperature measuring circuits are printed on second sides of the membranes where the electrodes are printed, and the heating circuits and the temperature measuring circuits are connected with the electrodes through holes formed in the membranes; the second sides of the membranes where the heating circuits and the temperature measuring circuits are printed are stacked on the non-punched membranes for lamination, and a sheet green body is formed; the sheet green body is sintered to obtain the sheet heating body of the electronic cigarette. According to the electronic cigarette, the sheetheating body of the electronic cigarette and the preparation method of the sheet heating body, the heating circuits and the temperature measuring circuits are sintered together with ceramic, so that the temperature of the heating body is uniformly distributed, and a temperature measuring area is reasonable and accurate.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an electronic cigarette, a sheet heating element thereof, and a preparation method of the sheet heating element. Background technique [0002] With the rapid development of low-temperature baking electronic cigarettes, its heating element has become the core component, which determines the overall design and performance quality level of electronic cigarettes. At present, most of the heating elements are directly inserted into the middle of the shredded tobacco (cigarette pod) with a heating body, and the heating body is directly wound with a wire with a certain resistance value. The heating resistance wire is in direct contact with the shredded tobacco. Hazardous substances are produced and there is an adverse risk to consumers. [0003] In some existing technologies, the heating wire is printed or grooved on the existing ceramic core to form a resistance circuit p...

AI Technical Summary

Problems solved by technology

At present, most of the heating elements are directly inserted into the middle of the shredded tobacco (drug cartridge) by the heating body, and the heating body is directly wound with a wire with a certain resistance value. The heating resistance wire is in direct contact with the shredded tobacco. Hazardous substances are produced and there is an adverse risk to consumers

[0003] In some existing technologies, the heating wire is printed or grooved on the existing ceramic core to form a resistance circuit pattern with a certain resistance value, and then a protective layer material is placed on the surface, because the two materials belong to secondary manufacturing. It is easy to cause the surface protective layer to fall off, so that the resistance wire directly contacts the shredded tobacco, and the heating element cannot be inserted into the shredded tobacco (cigarette cartridge) smoothly, which reduces the stability and service life of the heating element
