FIELD: smoking accessories.
SUBSTANCE: device with induction heating for generating microparticles of capturing and portable size includes an aerosol-forming substrate inside, has a cavity for a smoking article, including outer wrapping paper, and forms an aerosol by heating the aerosol-forming substrate of the smoking article, wherein the device for generating microparticles comprises: a multiple-wound excitation coil, installed inside the device; susceptor located inside the excitation coil so as to be surrounded by the excitation coil inside the device, which is made of a hollow cylindrical thin sheet defining a cavity, and is heated to temperature of 400° or lower by induction heating caused by eddy current losses during reaction with the excitation coil, wherein the inner surface of the susceptor is in contact with at least a portion of the outer surface of the wrapping paper of the smoking article placed in the cavity, and heated susceptor, by heating inductively, heats aerosol-forming substrate inside wrapping paper due to heat transfer, thereby forming an aerosol; an insulating part provided between the current collector and the excitation coil inside the device to prevent heat transfer from the current collector to the excitation coil; structure located inside the device for supporting at least a portion of one or more of the susceptor and the excitation coil; susceptor temperature obtaining unit located inside the device to obtain susceptor temperature; storage battery provided inside the device, which functions as a DC power supply; and a control unit electrically connected to the excitation coil, the susceptor temperature obtaining unit and the battery, which receives DC power from the battery, supplies to the excitation coil alternating current with resonant frequency or alternating current with frequency far from the resonant frequency, and inductively heats the susceptor to the specified temperature, wherein the structure includes a double-layer pipe consisting of a ferrite layer for preventing magnetic field leakage from the excitation coil and an insulating layer for preventing heat transfer from the susceptor to other components, which is configured to cover the outer side of the excitation coil.
EFFECT: invention provides easy control of heat release from the sensor by direct measurement of the sensor temperature.
