Description

Atomization components and aerosol generating devices

technical field

The present application belongs to the technical field of electronic atomization, and in particular relates to an atomization component and an aerosol generating device.

Background technique

A heat not burn (Heat Not Burning, HNB) device is an electronic device that heats without burning the aerosol-generating substrate (treated plant leaf products). The heating device heats the aerosol-generating substrate to a temperature at which the aerosol-generating substrate can generate the aerosol but is not high enough to burn through high temperature, so that the aerosol-generating substrate can generate the aerosol required by the user under the premise of not burning.

Heat-not-burn appliances currently on the market mainly adopt resistance heating, that is, use a central heating sheet or a heating needle to insert from the center of the aerosol-generating substrate into the interior of the aerosol-generating substrate for heating. This kind of appliance needs to be preheated for a long time before use, and it cannot be pumped and stopped freely. The carbonization of the aerosol-generating matrix is uneven, resulting in insufficient baking of the aerosol-generating matrix and low utilization rate; Dirt is generated in the matrix extractor and the base of the heating sheet, which is difficult to clean; the local aerosol in contact with the heating element will cause the temperature of the matrix to be too high, and partial cracking will occur, releasing substances harmful to the human body. Therefore, microwave heating technology has gradually replaced resistance heating as a new heating method. Microwave heating technology has the characteristics of high efficiency, timeliness, selectivity and no delay in heating, and it only has a heating effect on substances with specific dielectric properties. The application advantages of using microwave heating atomization are: a. Microwave heating is radiation heating, non-thermal conduction, which can realize immediate pumping and stop; b. There is no heating sheet, so there is no problem of broken pieces and cleaning heating sheets; c. Aerosol generation The matrix utilization rate is high, the taste consistency is high, and the taste is closer to cigarettes.

However, microwave heating atomization usually inserts the conductor post fed into the microwave into the aerosol generating matrix. After suction, the aerosol generating matrix is easy to stick to the conductor post set in the aerosol generating device due to the soot generated by high temperature heating and combustion. , and difficult to clean.
