Abstract: An inhalation device includes: a heater configured to generate aerosol by heating a substrate containing an aerosol source; and a control circuit configured to control an operation a of the heater based on a heating profile defining a time-series transition of a target temperature. The control circuit is configured to: start control of the heater in a control mode defined by the heating profile in response to a generation request for the aerosol; acquire information indicating an inhalation mode in a first period in which the heater is controlled in the control mode defined by the heating profile; and change the control mode for the heater in a second period after the first period from the control mode defined by the heating profile to a control mode based on the inhalation mode in the first period.

Abstract: A method for operating an electric power source unit for an inhaler is provided. The method includes making a sensor detect a puff action performed by a user; measuring detected-time that is a puff action period during that the detected puff action is continued; correcting the measured detected-time, by using a time correction model that is based on a characteristic parameter associated with the puff action; calculating accumulated detected-time by accumulating the corrected detected-time; and estimating a remaining quantity level of an inhaled component source, based on the accumulated detected-time.
