Title:
AEROSOL GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/214734
Kind Code:
A1
Abstract:
An aerosol-generating device is disclosed. The aerosol-generating device of the disclosure includes a chamber configured to store a liquid, a heater configured to heat the liquid, a resistance detection sensor configured to output a signal corresponding to a resistance of the heater, and a controller configured to calculate a temperature of the heater based on the resistance of the heater. The controller is configured to determine whether the temperature of the heater exceeds a first temperature in response to supply of sensing power to the heater in a first preheating period, control so that a first amount of power is supplied to the heater in a heating period after the first preheating period, based on the temperature of the heater being equal to or less than the first temperature, control so that a second amount of power less than the first amount of power is supplied to the heater in the heating period, based on the temperature of the heater exceeding the first temperature, determine whether the temperature of the heater exceeds a second temperature greater than the first temperature in response to supply of the sensing power to the heater in a second preheating period after the heating period, based on the temperature of the heater exceeding the first temperature, and determine that the liquid is exhausted based on the temperature of the heater exceeding the second temperature.
