Abstract

A flavor generation device comprising: a case; a first electronic component disposed in the case; a temperature sensor disposed in or in the vicinity of the first electronic component; a second electronic component disposed in the case; and a control device. The second electronic component is disposed away from the temperature sensor at a distance greater than a distance between the temperature sensor and the first electronic component. The control device is configured to detect or estimate the temperature of the second electronic component on the basis of an output value from the temperature sensor.

Claims (32)

1 . A flavor generation device comprising:

a case;

a first electronic component disposed in the case;

a temperature sensor disposed in the first electronic component;

a second electronic component disposed in the case; and

a controller configured to

determine or estimate a temperature of the second electronic component, based on an output value obtained from the temperature sensor, and

perform a predetermined control on the second electronic component when the output value obtained from the temperature sensor satisfies a predetermined condition.

2 . The flavor generation device according to claim 1 , wherein the first electronic component comprises the controller.

3 . The flavor generation device according to claim 1 , wherein the first electronic component comprises the controller, and wherein the controller is configured to perform the predetermined control on the second electronic component without performing a further control on the first electronic component when the output value obtained from the temperature sensor satisfies the predetermined condition.

4 . The flavor generation device according to claim 1 , wherein the second electronic component is a power supply.

5 . The flavor generation device according to claim 4 , wherein

the power supply comprises at least an electrolyte solution or an ionic liquid, and

the controller is configured to perform a protection control to protect the power supply when the output value obtained from the temperature sensor is lower than or equal to a first predetermined temperature at which the electrolyte solution or the ionic liquid freezes or when a temperature of the power supply is estimated, based on the output value obtained from the temperature sensor, to be lower than or equal to the first predetermined temperature.

6 . The flavor generation device according to claim 4 , wherein

the power supply is a lithium-ion secondary battery, and

the controller is configured to perform a protection control to protect the power supply when the output value obtained from the temperature sensor is lower than or equal to a second predetermined temperature at which electrodeposition occurs on an electrode of the power supply or when a temperature of the power supply is estimated, based on the output value obtained from the temperature sensor, to be lower than or equal to the second predetermined temperature.

7 . The flavor generation device according to claim 4 , wherein the controller is configured to perform a protection control to protect the power supply when the output value obtained from the temperature sensor is higher than or equal to a third predetermined temperature at which a structural or compositional change occurs in an electrode of the power supply or when a temperature of the power supply is estimated, based on the output value obtained from the temperature sensor, to be higher than or equal to the third predetermined temperature.

8 . The flavor generation device according to claim 4 , wherein the controller is configured to perform a protection control to protect the power supply when the output value obtained from the temperature sensor is less than 0° C. or greater than or equal to 60° C. or when a temperature of the power supply is estimated, based on the output value obtained from the temperature sensor, to be lower than 0° C. or higher than or equal to 60° C.

9 . The flavor generation device according to claim 1 , further comprising a load that heats or atomizes an aerosol source or a flavor source by using power supplied by the power supply, wherein

the controller is configured to control supply of power to the load.

10 . The flavor generation device according to claim 1 , wherein at least part of an outer shape of the first electronic component is cylindrical.

11 . The flavor generation device according to claim 1 , further comprising a heat transfer suppression unit in which the first electronic component and the temperature sensor are at least partially wrapped, the heat transfer suppression unit being configured to suppress transfer of heat between the first electronic component and the case.

12 . The flavor generation device according to claim 11 , wherein the heat transfer suppression unit forms a space in which the first electronic component and the temperature sensor are housed.

13 . The flavor generation device according to claim 1 , further comprising a thermally conductive member disposed between the first and second electronic components.

14 . The flavor generation device according to claim 1 , further comprising:

a first member in which the first electronic component and the temperature sensor are at least partially wrapped; and

a second member disposed between the first and second electronic components, wherein

a thermal conductivity of the second member is higher than a thermal conductivity of the first member.

15 . The flavor generation device according to claim 14 , wherein

the first electronic component and the temperature sensor are enclosed with the first and second members, and

the second member faces the second electronic component.
