Title:
INHALER AND METHOD FOR MANUFACTURING INHALER
Document Type and Number:
WIPO Patent Application WO/2021/181993
Kind Code:
A1
Abstract:
An inhaler comprising: a voltage regulator for generating voltage to supply power to a heater for heating an aerosol source; a resistor connected to the heater and the voltage regulator in series; a transistor for switching the amount of power to be supplied to the heater; an operational amplifier including an uninverted input terminal connected to a first end of the heater and an inverted input terminal connected to a second end of the heater for measuring a heater voltage applied to the heater; and a drive circuit connected between an output terminal of the operational amplifier and a control terminal of the transistor. The drive circuit continuously supplies an off-signal to the control terminal until an output signal of the operational amplifier becomes smaller than a threshold when the output signal is larger than the threshold, and continuously supplies an on-signal to the control terminal until the output signal becomes larger than the threshold when the output signal is smaller than the threshold.
