    摘要： An aerosol generating device includes a housing including a hollow portion and a body portion. The body portion includes a cavity formed at the bottom of the hollow portion. The aerosol generating device includes a membrane which partitions the cavity into an upper part and a lower part hermetically, and a pressure sensor which seals a bottom of the cavity and detects a pressure change in the lower part of the cavity which is caused by a puff on an aerosol generating article (e.g., cigarette) loaded in the aerosol generating device.

    摘要： An aerosol-generating device is disclosed. The aerosol-generating device of the present disclosure includes a cartridge, which includes a chamber configure to store a liquid, a wick for receiving the liquid from the chamber, and a heater for heating the wick, a case, to which the cartridge is detachably coupled and which has an insertion space formed to accommodate insertion of a stick therein, a first circuit including the heater, and a second circuit for sensing the temperature of the heater. The second circuit includes a first resistor, which is disposed to be in contact with or adjacent to the heater to receive heat from the heater, wherein a resistance value of the first resistor is variable based on changes in the temperature thereof, a second resistor connected to the first resistor, and a sensor for acquiring the value of current applied to the second resistor.
