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.
