Abstract
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.
