    摘要： According to some embodiments, an aerosol generating device may include a battery, a first control circuit configured to convert power received from the battery into a pulse width modulation (PWM) signal, a heater configured to heat an aerosol generating article based on the PWM signal received from the first control circuit, and a second control circuit configured to transmit an instruction for causing the first control circuit to generate the PWM signal, in response to a user input to the first control circuit. The first control circuit may determine abnormal operation of the second control circuit, and the second control circuit may determine abnormal operation of the aerosol generating device. Accordingly, the aerosol generating device may determine a more specific operation state and prevent abnormal operation of the heater.

    摘要： An aerosol generating device includes: an opening configured to receive a cigarette, an accommodation space configured to accommodate the cigarette inserted through the opening, a coil surrounding the accommodation space and configured to generate an induced magnetic field, a susceptor configured to generate heat due to the induced magnetic field generated from the coil, a heat dissipating structure surrounding the coil and having a double wall structure including a vacuum inner space, a shielding portion configured to block the induced magnetic field generated from the coil and disposed between the coil and the heat dissipating structure, a cigarette recognition sensor configured to detect changes in inductance of the cigarette recognition sensor which is generated by insertion or extraction of the cigarette, and a controller configured to determine whether the cigarette is inserted or extracted, based on the changes in inductance.

    摘要： Provided is an aerosol generating apparatus including: a heater configured to heat an aerosol generating article inserted into an accommodation space of the aerosol generating apparatus; a sensing module including at least one of an inductive sensor configured to detect a change in an inductance of the accommodation space or a temperature sensor configured to detect a change in a temperature of the heater; and a processor configured to: detect, via the sensing module, whether the aerosol generating article that is inserted into the accommodation space is at least partially moved from the accommodation space; and based on detecting that the aerosol generating article is at least partially moved from the accommodation space, control a power supply to the heater, based on at least one of the change in the inductance or the change in the temperature acquired via the sensing module.
