Abstract

A control unit of an aerosol generation device includes: a flow rate sensor configured to output a flow rate of inhalation by a user; and a processing device configured to acquire an atomization command of an aerosol source by an atomizer. The processing device is configured: to control discharge from a power supply to the atomizer, based on the atomization command; to acquire a flow rate per unit time during the inhalation corresponding to each atomization command, based on an output of the flow rate sensor; to acquire an inhalation time that is a length of the inhalation corresponding to each atomization command; and to acquire at least one of a remaining amount of a flavor source configured to add flavor to aerosol generated from the aerosol source and a consumed amount of the flavor source, based on the flow rate per unit time and the inhalation time.
