Description

Aerosol generating device

technical field

The present application belongs to the technical field of electronic atomization, and in particular relates to 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 heat-not-burn device heats the aerosol-generating substrate at a high temperature to a temperature at which the aerosol-generating substrate can generate aerosol but is not high enough to burn, and can allow the aerosol-generating substrate to generate the aerosol required by the user without burning.

At present, the HNB devices on the market mainly adopt the resistance heating method, that is, use a central heating sheet or a heating needle to insert from the center of the aerosol-generating matrix to the inside of the aerosol-generating matrix for heating. This kind of device needs to be preheated for a long time before use, and it cannot be pumped and stopped freely, and 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 sol-generating matrix extractor and the base of the heating sheet, which is difficult to clean; the temperature of the local aerosol-generating matrix in contact with the heating element will be too high, and partial cracking will occur, releasing harmful substances 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, the existing microwave-heated HNB device cannot timely control the stop operation of the microwave component after the user stops pumping, resulting in waste of electric energy and aerosol matrix.
