1. A temperature control method for an aerosol generation apparatus, wherein the aerosol generation apparatus comprises a detection element and a heating element for heating an aerosol generation base material, and the temperature control method comprises:
in a first stage, controlling the heating element to increase a temperature of the aerosol generation base material from an initial temperature to a first temperature;
in a second stage, controlling the heating element to decrease the temperature from the first temperature to a second temperature; and
in a third stage, controlling the heating element to provide a constant temperature operation at the second temperature, and during an instance where the detection element detects suction, controlling the heating element to increase the temperature to a third temperature;
wherein, during the third stage, detection of the suction by the detection element occurs within a first preset duration, the heating element is controlled to maintain the second temperature as constant for the first preset duration and, thereafter, the heating element is controlled to increase the temperature to the third temperature; and
wherein, in an absence of the detection element detecting the suction within the first preset duration, the heating element is controlled to operate continuously at the second temperature until termination of the third stage.
