Abstract (en)

[origin: EP4074200A1] [Problem] To provide a mechanism capable of improving the accuracy of detection of a puff. [Solution] This inhalation device is provided with: a heating unit for heating an aerosol source; a temperature varying unit, the temperature of which is increased due to heat generated by heating by the heating unit, and is decreased as a result of suction of an aerosol generated from the aerosol source heated by the heating unit; and a control unit for detecting suction of the aerosol when the manner of temperature decrease of the temperature varying unit meets a detection reference. The control unit changes the detection reference on the basis of the time elapsed from the start of heating of the aerosol source by the heating unit.
