Abstract

Official abstract text for this publication.

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; and 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. The power supply unit further includes a zener diode which is provided between the connector and the control device so as to be connected in parallel with the control device, and a maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the control device.

First claim

Opening claim text (preview).

What is claimed is: 1. 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 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, wherein a maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the control device, a minimum value of the zener voltage of the zener diode is higher than a minimum operation guarantee voltage of the control device, and a value which is obtained by subtracting the maximum value of the zener voltage of the zener diode from the maximum operation guarantee voltage of the control device is smaller than a value which is obtained by subtracting the minimum operation guarantee voltage of the control device from the minimum value of the zener voltage of the zener diode. 2. The power supply unit according to claim 1 , wherein the power supply unit further includes: a first circuit board on which the connector is provided; and a second circuit board which is apart from the first circuit board and on which the control device is provided, and the zener diode is provided on the first circuit board. 3. The power supply unit according to claim 2 , wherein the power supply unit further includes a resistor which is provided on the first circuit board so as to be connected in series with the connector and the zener diode. 4. The power supply unit according to claim 3 , wherein the resistor is connected between the control device and the zener diode. 5. The power supply unit according to claim 2 , wherein the power supply unit further includes a conductive member which electrically connects the first circuit board and the second circuit board. 6. The power supply unit according to claim 2 , wherein the power supply unit further includes a capacitor which is provided between the zener diode and the control device so as to be connected in parallel with the control device. 7. The power supply unit according to claim 6 , wherein the capacitor is provided on the second circuit board. 8. 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 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, wherein a maximum value of zener voltage of the zener diode is lower than a maximum operation guarantee voltage of the control device, a rated value for voltage which is supplied from the connector is higher than a minimum operation guarantee voltage of the control device, a minimum value of the zener voltage of the zener diode is higher than the rated value, and a value which is obtained by subtracting the maximum value of the zener voltage of the zener diode from the maximum operation guarantee voltage of the control device is smaller than a value which is obtained by subtracting the rated value for the voltage which is supplied from the connector from the minimum value of the zener voltage of the zener diode. 9. The power supply unit according to claim 8 , wherein the power supply unit further includes: a first circuit board on which the connector is provided; and a second circuit board which is apart from the first circuit board and on which the control device is provided, and the zener diode is provided on the first circuit board. 10. The power supply unit according to claim 9 , wherein the power supply unit further includes a resistor which is provided on the first circuit board so as to be connected in series with the connector and the zener diode. 11. The power supply unit according to claim 10 , wherein the resistor is connected between the control device and the zener diode. 12. The power supply unit according to claim 9 , wherein the power supply unit further includes a conductive member which electrically connects the first circuit board and the second circuit board. 13. The power supply unit according to claim 9 , wherein the power supply unit further includes a capacitor which is provided between the zener diode and the control device so as to be connected in parallel with the control device. 14. The power supply unit according to claim 13 , wherein the capacitor is provided on the second circuit board.
