Description

FIELD

The application belongs to the technical field of electronic atomization, and particularly relates to an atomization assembly and an aerosol generation device.

BACKGROUND

A heat-not-burning (HNB) device is a kind of electronic equipment that heats, but does not burn, an aerosol generating substarte (which is a product of processed plant leaves). The heating device heats, at a high temperature, the aerosol generating substarte to a temperature that can generate an aerosol, but is not sufficient to cause burning, so that, without being caused to burn, the aerosol generating substarte generates an aerosol desired by a user.
The HNB devices that are currently available in the market generally adopts resistor heating means, namely a central heating plate or a heating pin penetrates, at a central location of the aerosol generating substarte , into the interior of the aerosol generating substarte to proceed with heating. Such a device takes a long time to wait for preheating before use, making it hard to freely start or stop vaping, and the aerosol generating substarte cannot be uniformly carbonized, leading to insufficient baking of the aerosol generating substarte and low efficiency of utilization. Secondly, the heating plate of the HNB device may easily causes generation of contaminants, which are hard to cleanse, in an aerosol generating substarte extractor and a heating plate holder, and a portion of the aerosol generating substarte that is in contact with the heating body may get locally excessively high temperature, causing partial decomposition and releasing undesired substances. Thus, the resistor heating means is gradually replaced by microwave heating technology, which becomes a new solution of heating. The microwave heating technology has advantages in respect of high efficiency, timeliness, optionality, and non-delay heating, and is only effective of heating for specific substances having certain dielectric properties. Advantages of microwave heating based atomization include: (a) instantaneous vaping or stopping being achievable as the microwave heating is radiation based heating, rather than heat conduction; (b) there being no plate breaking or heating plate cleansing issues as no heating plate is involved; and (c) the utilization efficiency of the aerosol generating substarte being high and mouthfeel being consistent, and the mouthfeel being much closer to cigarettes.
However, to realize microwave heating-based atomization, a conductor pillar for feeding microwaves has to be inserted into the aerosol generating substarte, and tobacco dirt generated due to high-temperature heating and combustion of the aerosol generating substarte after vaping may be adhered to the conductor pillar in an aerosol generation device, which makes cleaning difficult.
