Abstract (en)
[origin: US2022071300A1] An inhalation device appropriately ascertains the state of a power supply part and, in particular, quickly and reliably detects the state when a power supply abnormality has occurred during battery discharge. An inhalation device generates an aerosol and includes a heating part that atomizes an aerosol source, a power supply part that performs an operation that supplies power to the heating part, a sensor that detects a voltage value for the power supply part, a control part that determines the state of the power supply part on the basis of a total power supply count and a normal power supply count that are tallied in accordance with the power supply operation, the normal power supply count being tallied when the voltage value for the power supply part is at or above a prescribed voltage threshold value throughout the power supply operation, and a notification part that gives notification of the state of the power supply part.
