Abstract: An inhalation component generating device includes: a power supply; a load group including a load configured to evaporate or atomize an inhalation component source by power from the power supply; an adjusting unit configured to adjust a value or waveform of voltage to be applied to the load; and a control circuit configured to be able to acquire a voltage value of the power supply. The control circuit performs: a process (a1) of acquiring a closed circuit voltage value of the power supply in a closed circuit state in which the power supply and the load group are electrically connected; and a process (a2) of controlling the adjusting unit based on the closed circuit voltage value.

Abstract: This inhalation component generation device comprises: a load which vaporizes or atomizes an inhalation component source using power from a power supply; and a control unit. The control unit comprises: a voltage sensor which uses a predefined correlation to convert the analog voltage value of a power supply to a digital voltage value and outputs the digital voltage value; and a power control unit which controls the supply of power from the power supply to the load on the basis of the digital voltage value. The control unit is configured to be capable of calibrating the correlation on the basis of changes in the digital voltage value or the analog voltage value obtained during charging of the power supply.

Abstract: To provide a control device for an aerosol inhalator capable of determining a residual amount of an aerosol source without being influenced by changes in temperature of a heater due to inhalation.
The aerosol inhalator is configured so that a temperature, during supply of an electric power or during aerosol generation, of the load which atomizes an aerosol source stored in a reservoir or retained by an aerosol base using heat generated by supply of electric power become higher when an inhalation is performed, the control device includes a sensor for obtaining a first value relating to the temperature of the load, and a controller, in which the controller is configured to determine depletion or insufficiency of the aerosol source in the reservoir or the aerosol base based on a comparison between a second value based on the first value and a threshold (850E), the threshold is a value obtained by adding a positive first predefined value to the second value when a first condition that a residual amount of the aerosol source in the reservoir or the aerosol base is sufficient and the aerosol is being generated in the load is satisfied, and the inhalation is not performed, in a case where the first value is increased when the temperature of the load is increased, and the threshold is a value obtained by subtracting the positive first predefined value from the second value when the first condition is satisfied and the inhalation is not performed, in a case where the first value is decreased when the temperature of the load is increased.
