Document Type and Number:
WIPO Patent Application WO/2023/105773
Kind Code:
A1
Abstract:
Provided is a power supply unit for an aerosol generation device that can manage the temperature of a heater with high accuracy. This power supply unit 100 comprises: a power supply ba; a sheet heater HTR that heats a flavor source; a first thermistor th1 and a second thermistor th2 the resistance values of which change in accordance with the temperature of the sheet heater HTR; an MCU 6 that controls, on the basis of the temperature of the sheet heater HTR acquired from the resistance value of the second thermistor th2, the supply of power to the sheet heater HTR from the power supply ba such that the temperature of the sheet heater HTR converges on a target temperature; and a protective circuit (AND gate 10, FF9, and operational amplifier OP2) that stops the supply of power to the sheet heater HTR from the power supply ba when the temperature of the sheet heater HTR acquired from the resistance value of the first thermistor ht1 becomes greater than or equal to a threshold value THD1.
