A power supply unit of an aerosol generating device includes: an accommodating portion with a bottom and cylindrical shape, which is configured to accommodate a columnar cartridge that stores an aerosol source in a state in which the cartridge is rotatable 360 degrees in a circumferential direction of the cartridge. A rotation suppressing portion configured to generate a frictional force between the cartridge and the rotation preventing portion so as to suppress rotation of the cartridge in the circumferential direction is provided on a bottom portion of the accommodating portion.

Power supply unit of aerosol generating device and aerosol generating device

A power supply unit for an aerosol inhaler, which causes an aerosol generated from an aerosol source to pass through a flavor source to add a flavor component of the flavor source to the aerosol, includes: a power supply configured to be dischargeable to a first load configured to heat the aerosol source and dischargeable to a second load configured to heat the flavor source; and a processing device. The processing device determines whether the second load can heat the flavor source. When it is determined that the second load can heat the flavor source, the processing device starts or continues discharging from the power supply to the second load as second discharging before starting discharging from the power supply to the first load as first discharging.

Power supply unit for aerosol inhaler, aerosol inhaler, and aerosol inhale system

A power supply unit for an aerosol inhaler, which causes an aerosol generated from an aerosol source to pass through a flavor source, includes: a power supply dischargeable to a first load configured to heat the aerosol source and dischargeable to a second load configured to heat the flavor source; a notification unit; a processing device; a circuit board; and a conductive portion configured to electrically connect the second load and the circuit board. The processing device is configured to detect adhesion of a liquid to the second load or entry of the liquid into the conductive portion. When the adhesion or the entry is detected, the processing device executes at least one of a notification action that causes the notification unit to execute a notification and a first fail-safe action including prevention of discharging from the power supply to the second load.

A power supply unit for an aerosol generation device includes: a power supply; a first connector connectable to an atomizer for atomizing an aerosol source; a second connector connectable to a heater for heating a flavor source; and a processing device configured to acquire a temperature of the flavor source or the heater. The processing device is configured to start second discharge from the power supply to the heater to make the temperature of the flavor source or the heater converge to a target temperature, before starting first discharge from the power supply to the atomizer, acquire an elapsed time between a start time point of current second discharge and an end time point of a later one of previous first discharge and previous second discharge, and increase power in the first discharge more and/or decrease the target temperature more as the elapsed time becomes longer.

Power supply unit for aerosol generation device, and aerosol generation device

A power supply unit for an aerosol generation device, the power supply unit including: a power supply; a first connector electrically connectable to an atomizer capable of atomizing an aerosol source and electrically connected to the power supply; a second connector electrically connectable to a heater capable of heating a flavor source and electrically connected to the power supply; and a processing device. The processing device is configured to generate the aerosol to which the flavor is added by controlling discharge from the power supply to the atomizer and the heater, acquire a remaining amount of the flavor source at a first timing after generation of the aerosol as a first remaining amount, and acquire a second remaining amount, which is a remaining amount of the flavor source at a timing between the first timing and a second timing when next generation of the aerosol starts.
