Definitions

• the present application relates to the technical field of atomization, and particularly to atomizers.
• An aerosol is a colloidal dispersion system formed by dispersing and suspending small solid or liquid particles in a gas medium.
• the aerosol can be absorbed by the human body through the respiratory system, providing users with a new alternative absorption method.
• An atomizer refers to a device that is adapted to form an aerosol from a stored atomizable medium by means of heating or ultrasound treatment.
• the existing atomizer used for atomizing the heat-not-burn aerosol-generating substrate includes a heating chamber. After the aerosol-generating substrate is inserted in the heating chamber, an external airflow enters the aerosol-generating substrate from the bottom of the substrate. The airflow and the effective substances such as aroma generated from the heated aerosol-generating substrate are mixed and then inhaled by the user. However, the airflow flowing into the bottom of the aerosol-generating substrate reduces the temperature of the aerosol-generating substrate, not allowing the substances in the aerosol-generating substrate to be thoroughly baked, so that the effective substances cannot be completely released, which leads to a decreased amount of the effective substances contained in the aerosol output from the atomizer, and thus reduces the user experience of the atomizer.
