Description

Aerosol generating device

Technical Field

The application relates to the technical field of atomization, in particular to an aerosol generating device.

Background

The aerosol is a colloid dispersion system formed by dispersing and suspending solid or liquid small particles in a gaseous medium, and the aerosol can be absorbed by a human body through a respiratory system, so that a novel alternative absorption mode is provided for users. An aerosol-generating device refers to a device that forms an aerosol from a stored nebulizable medium by means of heating or ultrasound, etc. Nebulizable media, including liquid, gel, paste or solid aerosol-generating matrices, are nebulized to deliver an aerosol for inhalation to the user, replacing conventional product forms and absorption modalities.

The microwave heating is used as a medium atomized by microwave radiation, and has the characteristics of instantaneity, integrity, selectivity and the like, and a separate heating body is not needed because the microwave heating utilizes the self-absorption of the heated substance.

Existing aerosol-generating devices that utilize microwave heating generally include an outer conductor and an inner conductor housed within the outer conductor, the outer conductor and the inner conductor together defining a resonant cavity, one end of an aerosol-generating substrate being inserted into the inner conductor. After the use, the residual aerosol-generating substrate needs to be taken out of the inner conductor, but residues are likely to be left in the aerosol-generating device during the taking out process and are difficult to clean, so that the use experience of a user is reduced; in the related art, there is also a relatively complex structure in which an additional extractor is used to extract the aerosol-generating substrate.
