An aerosol generation device according to an embodiment may comprise: a body having an inner space into which an aerosol-generating article is inserted from one surface of the body; a susceptor accommodated in the body to heat the aerosol-generating article; an induction coil surrounding the susceptor to generate an alternating magnetic field; and a control unit controlling operations of the aerosol generation device and including at least one processor, wherein the susceptor includes a hollow portion for increasing inductance of the susceptor during heating.

A method for determining whether a susceptor is changed, according to one embodiment, may comprise the operations of: applying a first signal to a coil of a heater so as to generate an alternating magnetic field having a first frequency; determining a first value of an electrical characteristic of the susceptor indicated by the first signal; applying a second signal to the coil of the heater so as to generate an alternating magnetic field having a second frequency; determining a second value of an electrical characteristic of the susceptor indicated by the second signal; and determining whether the susceptor is a changed susceptor, on the basis of the first value and the second value.

An aerosol generating device includes a battery, a DC/DC converter configured to boost a voltage of the battery to supply a boosted voltage to a first heater and a second heater, a first resistor circuit connected in series with the second heater and configured to detect a current flowing through the second heater, a second resistor circuit connected in series with the first resistor circuit and configured to reduce a peak value of the current flowing through the second heater, an operation switch configured to determine whether or not the current flows through the second heater, and a processor configured to control the battery, the DC/DC converter, and the operation switch.

An aerosol generating device includes a main body including a main body portion having an accommodation space into which an aerosol-generating article is inserted; a cap detachably coupled to the main body; a cartridge detachably coupled to the main body portion; a first sensor configured to detect whether the cap is attached or detached; a second sensor configured to detect whether the cartridge is attached or detached; a third sensor configured to detect a remaining amount of liquid in the cartridge; and a microcontroller electrically connected to the first sensor, the second sensor, and the third sensor. The microcontroller wakes up when a measurement value detected by the first sensor changes to a preset value or more and determines whether the cap is attached or detached, when it is determined that the cap has been removed from the main body, the microcontroller detects whether the cartridge is detached or not using the second sensor during a preset grace time, but when the microcontroller does not detect attachment or detachment of the cartridge during the grace time, the microcontroller switches to sleep mode when the grace time elapses, and during the sleep mode, the microcontroller wakes up when the measurement value detected by the third sensor changes to a preset value or more, and re-detects whether the cartridge is attached or detached using the second sensor.
