An aerosol generating device includes an accommodation space in a cylindrical shape for accommodating a cigarette, an induction coil wound along an outer surface of the accommodation space, a power supply for supplying electric power to the induction coil, a controller for controlling electric power supplied to the induction coil, and a shield film including a ferromagnetic material for shielding electromagnetic interference from electromagnetic waves emitted from the induction coil. The shield film surrounds only a portion of an outer surface of the induction coil to shield the electromagnetic interference from the electromagnetic waves having a frequency that does not exceed 500 kHz.

An aerosol generating device, including an inductance channel, includes: a heater configured to generate an aerosol by heating a cigarette; a cigarette insertion space into which the cigarette is inserted; a first inductance channel; a second inductance channel; and a controller configured to generate a control signal by using information received from the first inductance channel and the second inductance channel, wherein the controller measures, when an amount of a change in frequency of current flowing through the first inductance channel exceeds a first reference value due to an object adjacent to the cigarette insertion space, an amount of a change in frequency of current flowing through the second inductance channel and controls, when the measured amount of the change in frequency of the current is less than a second reference value, a power supply to the heater to be started.

An aerosol-generating device may include a housing defining at least one internal compartment. The housing may be waterproof. The aerosol-generating device may further include a power supply, an electric heater, and/or a haptic feedback device. Each of the power supply, electric heater, and/or haptic feedback device may be positioned within one or more of the at least one internal compartment.

Provided is an aerosol generation device including: a case into which a cigarette is insertable; a heater arranged in the case and configured to heat the cigarette inserted into the case; a mainstream smoke passage connecting an internal end portion of the cigarette to the outside; and a vaporizer configured to heat a liquid composition to generate aerosol and deliver the aerosol to the mainstream smoke passage, wherein at least a portion of the mainstream smoke passage extends in a direction crossing a longitudinal direction of the cigarette.

The invention relates to an aerosol-generating device comprising a main body, a mouthpiece, which is configured removably attachable to the main body and a two-piece Venturi portion. The two-piece Venturi portion comprises an inlet portion, an outlet portion, a main airflow channel extending between the inlet portion and the outlet portion and a constricted airflow channel arranged in the main airflow channel. The inlet portion of the two-piece Venturi portion is at least partly arranged in the main body when the mouthpiece is attached to the main body, and the outlet portion of the two-piece Venturi portion is at least partly arranged in the mouthpiece or integrated with the mouthpiece.

There is provided an aerosol generating device including: an aerosol generating material delivery element configured to absorb an aerosol generating material stored in the cartridge; a heating element configured to heat the aerosol generating material; a support that includes a through-hole and accommodates the heating element and the aerosol generating material delivery element such that an end of the heating element passes through the through-hole and is exposed to an outside of the support; and a connector comprising a terminal providing power, and coupled to the support such that the end of the heating element contacts the terminal.

Disclosed are a susceptor for an aerosol generation apparatus, and the aerosol generation apparatus. The susceptor includes: a metal body, which may be penetrated by a varying magnetic field to generate heat; and a protective layer, formed on the metal body, the protective layer containing a quasicrystal alloy material to reduce adhesion or deposition of organic matter from a smokable material on the surface of the susceptor. When in use, water vapor, aerosol condensation oil, and the like from the smokable material cannot spread on the surface of the quasicrystal alloy material, and can be maintained in a substantially spherical shape and can be easily separated from the susceptor. Meanwhile, solid-phase organic matter such as tobacco slag and carbon deposition falling on the susceptor is difficult to be stubbornly bound to the protective layer, without forming stubborn adhesion or deposition.

A heater assembly for accommodating and heating an aerosol generating article includes an accommodation space into which the aerosol generating article is inserted, a coil surrounding at least part of the accommodation space and configured to generate an induced magnetic field, and a susceptor disposed in the accommodation space and configured to generate heat according to the induced magnetic field, wherein, in a state in which the aerosol generating article is fully inserted into the accommodation space, a distal end portion of the susceptor is placed upstream of a boundary between the tobacco rod and the filter rod by a preset distance inside the aerosol generating article.

A water dispenser and a method of controlling a water dispenser are provided. The water dispenser may control power output of an induction heater having a hot water module based on changes in flow rate of water supplied or a temperature of water discharged.

A system and method for inductive heating of dispersed metallic particles is provided. The method includes: providing a particle-laden flow comprising a carrier phase comprising a carrier fluid and a dispersed phase comprising the dispersed metallic particles; exposing the dispersed metallic particles to a magnetic field for heating the dispersed metallic particles via at least one of hysteresis and Joules heating mechanisms; inductively heating the dispersed metallic particles in the particle-laden flow via the magnetic field; and controlling a flow configuration of the particle-laden flow by adjusting a flow parameter, the flow parameter being any one or more of an induction heating timescale, a particle thermal timescale, a heat diffusion in the carrier phase, and a particle clustering of the dispersed metallic particles.
