Ceramic heating element for heat-not-burn electronic cigarette and preparation method of ceramic heating element

Abstract

The invention discloses a ceramic heating element for a heat-not-burn electronic cigarette and a preparation method of the ceramic heating element. The ceramic heating element comprises a ceramic rod core; a ceramic casting diaphragm arranged on the outer side of the ceramic rod core; a collinear circuit arranged on the ceramic casting diaphragm and used for controlling heating of the ceramic heating body and measuring the temperature of the ceramic heating body; a bonding pad which is arranged at the tail end of the collinear circuit and is used for connecting the outer electrode and the collinear circuit; a ceramic flange sleeving the ceramic rod core, wherein the ceramic flange is arranged close to one end of the bonding pad; and a protective coating arranged on the outer circumferential surface of the ceramic rod core. By means of the mode, heating and temperature control can be collinear, the difficulty of the printing technology is simplified, the hysteresis phenomenon of temperature control of the ceramic heating body is prevented, the temperature control precision is high, high temperature cannot be generated in the using process, and harm of toxic and harmful substances generated by the high temperature to the human body is reduced.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a ceramic heating element for heat-not-burn electronic cigarettes and a preparation method thereof. Background technique [0002] The heat-not-burn electronic cigarette is a new type of electronic cigarette. The heating element heats the tobacco-like atomizing medium to generate smoke to achieve the suction effect. Compared with traditional combustible tobacco, this new type of electronic cigarette has a lower temperature. It only bakes the tobacco-like atomizing medium at low temperature, reducing the large amount of tar and other harmful substances produced by tobacco during high-temperature combustion, so the new type of electronic cigarette is healthier. [0003] Existing heating elements for e-cigarettes usually print the heating circuit and the temperature measuring circuit separately. During the preparation process, the circuit needs to be screen-printed twice, and the...

AI Technical Summary

Problems solved by technology

[0003] Existing heating elements for e-cigarettes usually print the heating circuit and the temperature measuring circuit separately. During the preparation process, the circuit needs to be screen-printed twice, and the two sets of lead wires are connected, which increases the difficulty of silk screen printing. In addition, the temperature measurement and heating are controlled separately. It is prone to hysteresis during use, and if the temperature is not controlled in time, it will be prone to continuous heating. If the temperature is too high, a large amount of tar and other toxic and harmful substances will be produced.
