Description

Aerosol-generating substrate, aerosol-generating device and system

Technical Field

The invention belongs to the technical field of electronic atomization, and particularly relates to an aerosol generating substrate, an aerosol generating device and an aerosol generating system.

Background

A Heat Not Burning (HNB) device is an electronic device that heats but does Not burn an aerosol generating substrate (a treated plant leaf preparation). The heating means is heated by the elevated temperature to a temperature at which the aerosol-generating substrate is capable of generating an aerosol but is not sufficiently combustible to enable the aerosol-generating substrate to generate the aerosol for the user's needs without combustion.

The non-combustion heating appliances currently on the market mainly employ a resistance heating method, that is, heating is performed by inserting a central heating sheet or a heating needle into an aerosol-generating substrate from the center thereof. The device needs long preheating waiting time before use, can not be freely pumped out and stopped, and the carbonization of the aerosol generating substrate is not uniform, so that the aerosol generating substrate is not fully baked and the utilization rate is low; secondly, the HNB device heating sheet is easy to generate dirt in the aerosol generating substrate extractor and the heating sheet base and is difficult to clean; the temperature of the local aerosol generating substrate contacting the heating element is overhigh, partial cracking occurs, and substances harmful to human bodies are released. Therefore, microwave heating technology is gradually replacing resistance heating method to become a new heating method. The microwave heating technology has the characteristics of high efficiency, timeliness, selectivity and no heating delay, and only has a heating effect on substances with specific dielectric characteristics. The application advantages of adopting microwave heating atomization are as follows: a. the microwave heating is radiation heating, is not heat conduction, and can realize the pumping and stopping immediately; b. the heating sheet is not needed, so that the problems of broken sheets and cleaning heating sheets are avoided; c. the aerosol generating substrate has high utilization rate, high consistency of taste and more similar taste to cigarettes.

However, locations in the aerosol-generating substrate close to the microwave emitting end can be heated evenly, and locations in the aerosol-generating substrate remote from the microwave emitting end are less effective in heating, resulting in a lower utilisation of the aerosol-generating substrate.
