1. An aerosol generating device comprising:
a main body including a controller and a battery; and
a cartridge detachably coupled to the main body,
wherein the controller periodically detects whether the cartridge is coupled to the main body while the aerosol generating device operates in a first mode, determines whether a preset period of time has elapsed based on the cartridge being determined to have been separated from the main body, and switches the aerosol generating device from the first mode to a second mode based on whether the cartridge is coupled to the main body before the preset period of time elapses.
