An atomization assembly including a metal cylinder and a magnetic induction coil. The magnetic induction coil is disposed around the metal cylinder. When the metal cylinder is in an electrified state, a heat is produced to heat a smoke material therein to produce smoke.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing having a storage chamber and a dispensing chamber, and a vaporization chamber in communication with the dispensing chamber. The storage chamber is configured to hold a first fraction of a vaporizable material and the dispensing chamber is configured to hold a second fraction of the vaporizable material. The dispensing chamber is further configured to selectively dispense at least a first portion of the second fraction of the vaporizable material through at least one dispense opening in response to generation of one or more pressure pulses created within the dispensing chamber. The vaporizable chamber is configured to receive the dispensed vaporizable material from the dispensing chamber for vaporization by a first heating element to form a vaporized material. Vaporizer devices are also provided.

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.

A nicotine delivery device (200) for generating a mist containing nicotine for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

The present disclosure describes a personal vaporizer which can detect whether or not a cartridge of the personal vaporizer has been breached. The cartridge includes a conductive shell. The conductive shell can include two or more conductors which are electrically isolated from each-other. Prior to operation, the personal vaporizer can use the two or more conductors to assess whether or not an outer shell of the cartridge has been breached. In some implementations, if it is determined that the cartridge has been breached, the personal vaporizer can shut down, or otherwise fail to operate normally.

A method of controlling a heater in an aerosol-generating device is provided, the device including: a heater including a heating element configured to heat an aerosol-forming substrate, and a power source configured to provide power to the heating element; and the method including the steps of: controlling power provided to the heating element such that in a first phase, power is provided to increase a temperature of the heating element from an initial temperature to a first temperature, and in a second phase, power is provided to decrease the temperature of the heating element below the first temperature to a second temperature, the power being provided to the heating element during the first phase is increased at least once during a duration of the first phase, and aerosol is produced during the second phase.

An aerosol generation device includes a case into which a cigarette is to be inserted; a protrusion pipe of a hollow shape protruding from one end portion of the case and having an opening; a heater installed in the case such that an end portion thereof is positioned inside the protrusion pipe, and configured to generate heat when an electric signal is applied thereto; and a heater fixing portion installed inside the protrusion pipe to support the heater and comprising a round surface that extends from an inner side surface of the protrusion pipe.

Provided herein are a sidestream smoke removal device and a control method thereof. The sidestream smoke removal device according to some embodiments of the present disclosure includes a housing in which a smoking space is formed, an article insertion portion which is disposed at one end of the housing and forms an opening for insertion of a smoking article into the smoking space, an ignition portion which is configured to ignite the smoking article inserted into the smoking space, a sidestream smoke processing portion which is configured to process sidestream smoke generated from the smoking article inserted into the smoking space, and a cutting portion. The cutting portion may provide a cutting function for the smoking article inserted into the smoking space and thus ensure a convenient, safe extinguishing function.

A storage tube assembly, with a cap having a top surface and a sealing member connected to the top surface, the sealing member has a generally cylindrical upper wall and a generally cylindrical lower wall, the sealing member also has a recessed portion between the upper wall and lower wall and a flange cut into the lower wall; a sealing ring, the sealing ring is sized to cooperate with and be received in the recessed portion of the sealing member of the cap; and a tube, the tube has a generally circular inner wall with a cut therein, the cut in the inner wall is positioned to receive the sealing ring when the sealing ring is positioned within the recessed portion of the cap and the cap is placed into an open end of the tube.

A battery unit is installed in a flavor inhaler with an atomizing unit that atomizes an aerosol-generating material according to a puffing action of inhaling air through an air passage leading from an air inlet to an air outlet. The battery unit includes a battery, an electronic component configured to control the atomizing unit, and a housing configured to accommodate the battery and the electronic component. The electronic component is located in a predetermined portion of the battery unit. The predetermined portion includes a water detection member configured to detect water that enters the predetermined portion.
