Abstract: Provided is an aerosol generation device, the aerosol generation device comprising a chamber for receiving at least some of a smokable material; a magnetic field generator configured to generate a varying magnetic field; a susceptor configured to be penetrated by the varying magnetic field so as to generate heat, thereby heating the at least some smokable material received in the chamber; and a circuit configured to determine the temperature of the susceptor by acquiring a resistance value of the at least some of the material on the susceptor and on the basis of the resistance value. According to the aerosol generation device of the present application, the temperature of the susceptor is determined by measuring the resistance of the susceptor, and compared with a temperature measuring mode using a temperature sensor, production and preparation are more convenient and rapider, and the temperature measuring effect is more accurate.

Abstract: An aerosol generation device comprises a susceptor configured to be penetrated by a varying magnetic field to generate heat, so as to heat a smokable material; a circuit; and a temperature sensor comprising a sensing portion packaged or accommodated within the susceptor, and an electrical connection portion connected to the sensing portion and at least partially located outside the susceptor. The circuit is electrically connected to the electrical connection portion, so that the temperature sensed by the sensing portion can be received by the electrical connection portion. In the aerosol generation device, the temperature sensor is packaged or accommodated within the susceptor, the effect of a magnetic field on the sensing portion can be substantially isolated, and the susceptor and the temperature sensor can be integrated into one piece, improving the stability of installation and the accuracy of temperature measurement, and also facilitating replacement and installation as a whole.
