Patent ID: 8079363

Claim:
An inhaler for use in a user's inhalation of a liquid, comprising: a liquid ejection head for ejecting a liquid; and a drive unit for reading a voltage data from a plurality of preset voltage data respectively corresponding to preset time intervals, and driving said liquid ejection head at a drive voltage specified based on the read voltage data, wherein said drive unit comprises: a drive pulse control circuit for controlling a drive pulse signal of the liquid ejection head; a voltage table for recording a drive voltage corresponding to each time interval as voltage data; a drive voltage specifying circuit for specifying the drive voltage by reading the voltage data from the voltage table; a time control circuit for instructing said drive voltage specifying circuit to read the voltage data from said voltage table corresponding to each time interval in synchronization with the drive pulse signal; and a drive voltage control circuit for outputting at the specified drive voltage to the liquid ejection head based on the drive pulse signal.
