Provided is an aerosol generating apparatus including: a heater configured to generate aerosol by heating a cigarette, the heater including a first electrically conductive heating element formed along a first path on an electrically insulating substrate, a second electrically conductive heating element formed along a second path on the electrically insulating substrate, and a temperature sensor track formed along a third path in a region between the first path and the second path; a battery configured to supply power to the heater; and a controller configured to control the power supplied from the battery to the heater and monitor a temperature sensed using the temperature sensor track.

To provide a control device for an aerosol inhalator capable of compensating changes in temperature of a heater due to inhalation. A control device for an aerosol inhalator includes a first sensor for obtaining a first value relating to a temperature of a load which atomizes an aerosol source stored in a reservoir or retained by an aerosol base using heat generated by supply of electric power, a second sensor configured to detect an inhalation, and a controller, wherein the controller is configured to determine, based on a second value based on the first value and a threshold, whether the aerosol source in the reservoir or the aerosol base is depleted or insufficient (850A), and correct at least one of the second value and the threshold when detecting the inhalation (840) and, in the determination, compare the second value and the threshold, at least one of the second value and the threshold being corrected (842).

Features relating to vaporizer devices configured to allow for user control of a vaporizer session are provided. Session size selection and temperature selection options allow for a user to select a desired session size and a desired temperature for the vaporizer session. A session control user interface is provided on a user device to allow for user selections and to provide for user viewing of a status of the vaporizer session.

A power supply unit for an aerosol inhaler includes: a power supply able to discharge power to a load for generating an aerosol from an aerosol source; a connector able to be electrically connected to an external power supply; a control device configured to control at least one of charging and discharging of the power supply or configured to be able to convert power which is input from the connector into charging power for the power supply; and a zener diode provided between the connector and the control device so as to be connected in parallel with the control device. A maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the control device.

A heater assembly includes a container including a cylindrical portion that forms a chamber in which a flavor generating article is contained, and a heater arranged in a peripheral surface of the cylindrical portion. The container includes a first channel extending along a longitudinal direction of the cylindrical portion and located adjacently to the chamber in a direction intersecting with the longitudinal direction of the cylindrical portion, and a second channel extending through the chamber along the longitudinal direction of the cylindrical portion. The first channel is in communication with the second channel.

An aerosol-generating device includes a heating chamber structure, a heater coupled to the heating chamber structure, and a compression assembly. The heating chamber structure defines a fixed-volume enclosure and is configured to hold an aerosol-forming substrate within a first region of the enclosure. The heater is proximate to a first surface that at least partly defines the first region and is configured to generate heat that is transmitted into the first region to cause the aerosol-forming substrate to form an aerosol without any combustion. The compression assembly includes a compression plate and a compression actuator. The compression plate and the first surface define opposing boundaries of the first region. The compression actuator moves the compression plate through the enclosure to adjustably compress the aerosol-forming substrate in the first region against the first surface.
