| (54) | CONTROL UNIT OF AEROSOL GENERATION DEVICE |
| (57) 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.
