Abstract:
An aerosol-generating device may include a first heater for generating a first aerosol and a second heater for heating a second aerosol-generating substrate, and may significantly increase the initial atomization amount of the aerosol generating device by heating the second heater based on a preheating time of the first heater in a preheating section for increasing the temperatures of the first heater and the second heater.
