Abstract
A power supply unit for an aerosol inhaler includes: a power supply able to discharge power to a load for generating an aerosol from an aerosol source; a connector able to be electrically connected to an external power supply; a control device configured to control at least one of charging and discharging of the power supply or configured to be able to convert power which is input from the connector into charging power for the power supply; and a zener diode provided between the connector and the control device so as to be connected in parallel with the control device. A maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the control device.

A power supply unit for an aerosol inhaler, the power supply unit comprising:
- a power supply able to discharge power to a load for generating an aerosol from an aerosol source;
- a connector able to be electrically connected to an external power supply;
- a processor that controls at least one of charging and discharging of the power supply;
- a charger that converts power input from the connector into charging power for the power supply;
- and
- a zener diode that is connected between the connector and the charger and in parallel with the charger, wherein
- a voltage between both ends of the zener diode is fixed to a breakdown voltage of the zener diode to eliminate pulsation of a voltage supplied from the connector and stabilize an output voltage to the charger, and
- a maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the charger.
