Title:
AEROSOL-GENERATING DEVICE AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/068793
Kind Code:
A1
Abstract:
An aerosol-generating device and an operation method thereof are disclosed. The aerosol-generating device of the disclosure includes a housing having an insertion space defined therein, a heater, a resistance detection sensor for outputting a signal corresponding to the resistance of the heater, and a controller for determining the resistance of the heater in response to the signal from the resistance detection sensor. The controller determines an initial resistance of the heater in response to insertion of a stick into the insertion space, performs control such that power is supplied to the heater based on a predetermined temperature profile, determines whether to change the initial resistance based on the temperature of the heater calculated based on the initial resistance and a predetermined temperature range, and changes the initial resistance based on the difference between the calculated temperature of the heater and a predetermined reference temperature.
