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 generation source; a temperature measuring unit configured to measure temperature of the power supply; and a control device configured to control first power or a first amount of power to be supplied to the power supply in a case where a measurement value of the temperature measuring unit is equal to or higher than a first threshold, to a value smaller than second power or a second amount of power to be supplied to the power supply in a case where the measurement value is lower than the first threshold.

Claims (41)

1. A power supply unit for an aerosol inhaler, the power supply unit comprising:

a case;

a power supply which is able to discharge power to a load for generating an aerosol from an aerosol generation source and which is stored in the case;

a temperature measuring unit stored in the case to measure temperature of the power supply; and

a control device configured to control first power or a first amount of power to a value smaller than second power or a second amount of power, wherein the first power or the first amount of power is supplied to the power supply in a case where a measurement value of the temperature measuring unit is equal to or higher than a first threshold and the second power or the second amount of power is supplied to the power supply in a case where the measurement value is lower than the first threshold.

2. The power supply unit according to claim 1 , wherein

the temperature measuring unit is stored in the case so as to be close to the power supply.

3. The power supply unit according to claim 1 , wherein

in a case where the measurement value is equal to or higher than a second threshold larger than the first threshold, the control device stops charging of the power supply.

4. The power supply unit according to claim 1 , wherein

the first threshold is lower than 45° C.

5. The power supply unit according to claim 1 , wherein

the control device controls the first power or the first amount of power to 50% or less of the second power or the second amount of power.

6. The power supply unit according to claim 5 , wherein

the control device controls the first power or the first amount of power to 40% or less of the second power or the second amount of power.

7. The power supply unit according to claim 1 , wherein

in a case where the measurement value is equal to or higher than a second threshold larger than the first threshold, the control device stops charging of the power supply, and

in a case where the measurement value is equal to or higher than the first threshold and is lower than the second threshold, the control device controls the first power or the first amount of power such that the measurement value does not become equal to or higher than the second threshold.

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 generation source;

a temperature measuring unit configured to measure temperature of the power supply; and

a control device configured to control first power or a first amount of power to a value smaller than second power or a second amount of power, wherein the first power or the first amount of power is supplied to the power supply in a case where a measurement value of the temperature measuring unit is equal to or higher than a first threshold and the second power or the second amount of power is supplied to the power supply in a case where the measurement value is lower than the first threshold, wherein

in a case where the measurement value is equal to or higher than a second threshold larger than the first threshold, the control device stops charging of the power supply, and

a value which is obtained by subtracting the first threshold from the second threshold is equal to or larger than an absolute value of an error of the temperature measuring unit in measuring the temperature.

9. The power supply unit according to claim 1 , wherein

the first threshold is 43° C. or lower, and

the control device controls the first power or the first amount of power to 40% or less of the second power or the second amount of power.

10. The power supply unit according to claim 1 , further comprising:

a charger configured to convert power which is input, into charging power for the power supply,

wherein, among the charger and the control device, only the control device includes the temperature measuring unit.

11. The power supply unit according to claim 10 , wherein

the control device performs control on switching between a state where the temperature of the power supply can be acquired and a state where the temperature of the power supply cannot be acquired.

12. 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 generation source;

a temperature measuring unit configured to measure temperature of the power supply;

a control device configured to control first power or a first amount of power to a value smaller than second power or a second amount of power, wherein the first power or the first amount of power is supplied to the power supply in a case where a measurement value of the temperature measuring unit is equal to or higher than a first threshold and the second power or the second amount of power is supplied to the power supply in a case where the measurement value is lower than the first threshold;

a charger configured to convert power, which is input, into charging power for the power supply,

wherein the charger includes an information input part provided for detecting temperature of an element that is connected, and is configured to be able to supply one of a first charging voltage and a second charging voltage lower than the first charging voltage to the power supply, based on an input value which is input from the information input part,

a fixed value which is predetermined as one input value can be input to the information input part,

the fixed value is a value for supplying the second charging voltage to the power supply, among the charger and the control device, only the control device acquires the temperature measured by the temperature measuring unit, and

the control device selectively performs an input and a non-input of the fixed value to the information input part based on the temperature to control the power or the amount of power supplied from the charger to the power supply.
