That is, the inhaler device 100 operates based on the operation setting of the use subject. More specifically, the controller 116 controls the operation of each structural element of the inhaler device 100 including the heater 121 based on the operation setting of the use subject. An example of the operation setting will be described below.
  • the operation setting may include a heating profile.

  • the heating profile is information indicating a time-series transition of a target value for a value measured for the heater 121 (hereinafter, also referred to as an actual measurement value).
  • the controller 116 controls the operation of the heater 121 so that a time-series transition of an actual measurement value measured for the heater 121 becomes similar to the time-series transition of the target value defined in the heating profile. Accordingly, an aerosol is generated as planned in the heating profile.
  • the heating profile is typically designed to optimize the flavor that the user tastes when the user inhales the aerosol generated from the stick substrate 150.

As a result, it is possible to optimize the flavor that the user tastes.
  • the heating profile includes one or more combinations of an elapsed time since a start of heating and a target temperature to be reached within the elapsed time. Then, the controller 116 controls the temperature of the heater 121 based on the difference between the current actual temperature and the target temperature in the heating profile corresponding to the elapsed time since the start of the current heating.
  • the control on the temperature of the heater 121 can be implemented by, for example, known feedback control. Specifically, the controller 116 causes the electric power from the power supply 111 to be supplied to the heater 121 in the form of a pulse by pulse width modulation (PWM) or pulse frequency modulation (PFM). In this case, the controller 116 can control the temperature of the heater 121 by adjusting the duty ratio of the electric power pulse.

  • the controller 116 may control the electric power supplied to the heater 121, for example, the above-described duty ratio, based on the difference or the like between the actual temperature and the target temperature.
  • the feedback control may be, for example, a proportional-integral-differential controller (PID controller).
  • PID controller proportional-integral-differential controller
  • the controller 116 may perform simple ON-OFF control. For example, the controller 116 may execute heating by the heater 121 until the actual temperature reaches the target temperature, stop heating by the heater 121 when the actual temperature has reached the target temperature, and execute heating again by the heater 121 when the actual temperature becomes lower than the target temperature.
  • the temperature of the heater 121 can be quantified by, for example, measuring or estimating a resistance value (more accurately, an electrical resistance value) of the heater 121 (more accurately, a heat producing resistor constituting the heater 121). This is because the resistance value of the heat producing resistor changes with the temperature.
  • the resistance value of the heat producing resistor can be estimated, for example, by measuring the amount of voltage drop in the heat producing resistor.
  • the amount of voltage drop in the heat producing resistor can be measured by a voltage sensor that measures the potential difference applied to the heat producing resistor.
  • the temperature of the heater 121 can be measured by a temperature sensor installed near the heater 121.
  • a time section from the start to the end of processing of generating an aerosol using the stick substrate 150, more specifically, a time section during which the heater 121 operates based on the heating profile is hereinafter also referred to as a heating session.
  • the start of the heating session is a timing at which heating based on the heating profile is started.
  • the end of the heating session is a timing at which a sufficient amount of aerosol is no longer generated.
