摘要： 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.

摘要： An aerosol inhaler includes: a first branch circuit including a load, a first resistor, and a first node; a second branch circuit including a second resistor, a third resistor, and a second node; an operational amplifier of which a non-inverting input terminal is connected to one of the first node and the second node, and of which an inverting input terminal is connected to the other of the first node and the second node; and a control device having an upper limit temperature and a lower limit temperature. A differential input of the operational amplifier is larger than potential of a negative power supply terminal of the operational amplifier or a minimum value acquirable by the operational amplifier in a first temperature range, and is equal to the potential of the negative power supply terminal of the operational amplifier or the minimum value in a second temperature range.

摘要： 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.
