Description
Technical Field
The invention belongs to the technical field of electronic cigarettes, and particularly relates to an aerosol generating device and a control method of the aerosol generating device.
Background
A Heat Not Burn (HNB) device is an electronic device that heats but does Not burn an aerosol generating substrate (treated plant leaf product). The heating device heats the aerosol-generating substrate to a temperature at which the aerosol-generating substrate can generate aerosol but is insufficient for combustion, and can enable the aerosol-generating substrate to generate aerosol required by a user without combustion.
The heating non-combustion apparatus in the market at present mainly adopts a resistance heating mode, namely, a central heating plate, a heating needle and the like are utilized to be inserted into an aerosol generating substrate from the center of the aerosol generating substrate for heating. The device has long preheating waiting time before use, can not be freely stopped, and the aerosol generating substrate is carbonized unevenly, so that the aerosol generating substrate is not sufficiently baked and has low utilization rate; secondly, the heating sheet of the HNB device is easy to generate dirt in the aerosol generating substrate extractor and the heating sheet base, and is difficult to clean; the partial aerosol contacting the heating element can generate the substrate with overhigh temperature and partial cracking, and release substances harmful to human body. Therefore, the microwave heating technology gradually replaces the resistance heating mode to become a new heating mode. The microwave heating technology has the characteristics of high efficiency, timeliness, selectivity and no delay in heating, and only has the heating effect on substances with specific dielectric characteristics. The application advantages of microwave heating atomization are as follows: a. the microwave heating is radiation heating, is not heat conduction, and can realize pumping and stopping at once; b. the heating plate is not needed, so that the problems of broken pieces and cleaning of the heating plate are avoided; c. the aerosol generating substrate has high utilization rate, high taste consistency and taste similar to cigarettes.
However, when the cavity loaded with the microwave device is opened, the microwave device continuously emits microwaves, which may cause injury to surrounding personnel, and it is difficult to ensure the use safety of users.
