Abstract: This application provides an aerosol generation device and a control method thereof. The aerosol generation device includes, a housing, provided with a through hole and an air inlet; a cavity, where an aerosol-forming substrate is received in the cavity or removed from the cavity through the through hole; a heater, configured to heat the aerosol-forming substrate received in the cavity; a heat drain device, arranged on a gas flow path extending between the air inlet and the through hole; and a circuit, configured to, after the heater starts for heating and before the heater enters an inhalation stage, control the heat drain device to start operation to drain hot air generated by heating out of the housing along the gas flow path. Before a smoker inhales on the aerosol generation device, the heat drain device drains an aerosol comprising vapor out of the housing.

Abstract: An aerosol-generating device comprises an infrared emitter and an electric core for supplying power to the infrared emitter; the infrared emitter comprises at least one first infrared emission region and at least one second infrared emission region arranged in sequence along the circumferential direction of the chamber; the first infrared emission region and the second infrared emission region are independently activatable to independently radiate infrared rays into the chamber to heat different portions of the smokable material. In the above aerosol-generating device, the regions of the smokable material receiving chamber which are different along the circumferential direction correspond to the first infrared emission region and the second infrared emission region, respectively, and can be independently heated by the first infrared emission region and the second infrared emission region, respectively, in use, so that the smokable material can be gradually heated from part to whole in use.

Abstract: An aerosol generating device comprises a magnetic field generator and a heater for heating a smokable material; the heater comprises a susceptor portion and an infrared emission portion, the susceptor portion is penetrated by a magnetic field to generate heat and heat the smokable material by heat conduction, and the infrared emission portion receives the heat of the susceptor portion, and is excited by heating to radiate infrared rays to heat the smokable material. During the use of the above aerosol generating device, on the one hand, the susceptor portion generates heat by inductive heating so that the smokable material is directly heated by heat conduction; and on the other hand, the infrared emission portion is excited by the heat of the susceptor portion to radiate infrared rays, thereby assisting in the heating of the smokable material, and improving the utilization efficiency of heat.
