Abstract (en)
An aerosol generating device comprises: a heating unit configured to heat an aerosol source; a power supply configured to supply electric power to the heating unit; a thermistor configured to output a value depending on a temperature of the heating unit; and a control unit configured to control the supply of electric power from the power supply to the heating unit in accordance with a control sequence including a first section in which electric power is supplied to the heating unit by setting a target value of temperature control at a value corresponding to a first temperature, a second section in which the supply of electric power is stopped so that the temperature of the heating unit falls toward a second temperature lower than the first temperature, and a third section in which electric power is supplied the heating unit. The control unit is configured to controls the supply of electric power from the power supply by using a first temperature index based on an electrical resistance value of the heating unit, in the first and third sections, and determine a timing to terminate the second section by using a second temperature index based on the output value from the thermistor.
