Description

FIELD OF THE INVENTION

The present invention relates to the technical field of electronic atomization, and particularly to an aerosol generation device.

DESCRIPTION OF THE RELATED ART

A heat-not-burning (HNB) device is a kind of electronic equipment that heats, but does not burn, an aerosol generating base material (which is a product of processed plant leaves). The heating device heats, at a high temperature, the aerosol generating base material 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 base material generates an aerosol desired by a user.
The HNB devices that are currently available in the market generally adopts resistor heating means, namely a centered heating plate or a heating pin penetrates, at a center location of the aerosol generating base material, into the interior of the aerosol generating base material 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 base material cannot be uniformly carbonized, leading to insufficient baking of the aerosol generating base material 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 base material extractor and a heating plate holder, and a portion of the aerosol generating base material 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 base material being high and mouthfeel being consistent, and the mouthfeel being much closer to cigarettes.
Further, for the resistor heating based HNB devices, controlling of the heating temperature uses a thermocouple to provide feedbacks of measurement to control output of electrical current or electrical voltage in order to achieve the purpose of temperature controlling. Requirement for consistency and accuracy of electrical parameters of the heating plates is extremely high, and the accuracy of temperature controlling is poor, and the inaccurate temperature controlling may easily generate undesired substances. For microwave heating based HNB devices, since heating with microwave may generate a strong electromagnetic field, and under such a strong electromagnetic field, when a regular temperature detection member is used to detect a temperature, a temperature detection probe that is made of a metallic material and conductor wires may generate an inducted current in the high-frequency electromagnetic field, and due to the skin effect and the eddy current effect, they may raises their own temperatures and may easily induce sparking, causing severe influence on temperature measurement, and generating a great error of the temperature readings or being unable to stably perform temperature measurement.
