Abstract
An inhaler and a direct current power supply voltage control device with a relatively simple structure that output a predetermined drive voltage according to a specified time interval to a drive object such as a heating resistor. An inhaleris equipped with a liquid ejection head, and is set so that a user is able to inhale liquid droplets ejected from the liquid ejection head. The inhalerincludes: specifying meansandfor specifying a drive voltagebased on preset voltage datarespectively corresponding to preset time intervals that respectively specify the drive voltageof the liquid ejection headin synchronization with the start of control of a drive signalof the liquid ejection head; and drive meansandfor driving the liquid ejection headaccording to the drive signalat the specified drive voltage
