Abstract

The invention pertains to the field of smoking devices, and provides an aerosol generation device (10) and a control method thereof. The method comprises: controlling a heater (101) to rise from an initial temperature to a first pre-determined temperature (S11); if the heater (101) has risen from the initial temperature to the first pre-determined temperature, controlling the heater (101) to maintain the first pre-determined temperature for a first pre-determined duration (S12); and controlling a sum of the duration of the heater (101) to rise from the initial temperature to the first pre-determined temperature and the first pre-determined duration to be greater than or equal to a second pre-determined duration (S13).
