Abstract

The present invention provides an aerosol generation system comprising: a controller for an inhalation device, the controller including a first power supply, a first connector, and a first processor configured to perform energization control of a heater which is used to heat an aerosol source, and a power supply device including a second power supply, a second connector which is connected to the first connector at the time of charging of the first power supply, and a second processor configured to perform control of power supply from the second power supply to the controller via the second connector, wherein a first voltage applied to a power supply terminal of the first processor and a second voltage applied to a power supply terminal of the second processor are different from each other.

Claims (55)

1. An aerosol generation system comprising:

a controller for an inhalation device, the controller including a first power supply, a first connector, and a first processor configured to perform energization control of a heater which is used to heat an aerosol source;

a power supply device including a second power supply, a second connector which is connected to the first connector at the time of charging of the first power supply, a second processor configured to perform control of power supply from the second power supply to the controller via the second connector;

a linear regulator on a first line connecting the second power supply and a power supply terminal of the second processor; and

a DC/DC converter configured to convert a voltage supplied from the second power supply and output the converted voltage to the second connector, wherein

a first voltage applied to a power supply terminal of the first processor such that the first processor is capable of performing the energization control and a second voltage applied to a power supply terminal of the second processor such that the second processor is capable of performing the energization control are different from each other, and

the DC/DC converter is not connected to the second power supply via the linear regulator.

2. The system of claim 1 , wherein

the first processor is configured to perform energization control of the heater and to perform a temperature calculation process of calculating an estimated temperature of the heater.

3. The system of claim 2 , wherein

the first voltage applied to the power supply terminal of the first processor is a voltage sufficient for the first processor to perform the temperature calculation process during the energization control.

4. The system of claim 1 , wherein

the first voltage applied to the power supply terminal of the first processor is a voltage sufficient for the first processor to operate at a first processing speed, and

the second voltage applied to the power supply terminal of the second processor is a voltage sufficient for the second processor to operate at a second processing speed, which is different from the first processing speed.

5. The system of claim 4 , wherein

the second processing speed is lower than the first processing speed.

6. The system of claim 5 , wherein

the first voltage is higher than the second voltage.

7. The system of claim 1 , wherein

the first voltage is applied to the power supply terminal of the first processor via a second line connecting the first power supply and the power supply terminal of the first processor.

8. The system of claim 7 , wherein

the second voltage is applied to the power supply terminal of the second processor via the first line connecting the second power supply and the power supply terminal of the second processor.

9. The system of claim 1 , wherein

the first voltage is higher than the second voltage.

10. The system of claim 1 , wherein

the linear regulator outputs, as the second voltage, a voltage lower than the first voltage.

11. The system of claim 10 , wherein

the controller includes, on a second line connecting the first power supply and the power supply terminal of the first processor, no component that causes a larger voltage drop than the linear regulator.

12. The system of claim 11 , wherein

the controller comprises a diode on the second line.

13. The system of claim 1 , wherein

in a state in which the first connector is connected to the second connector, a third voltage is applied from the power supply device to the power supply terminal of the first processor.

14. The system of claim 13 , wherein

the third voltage is different from the second voltage.

15. The system of claim 14 , wherein

the third voltage is higher than the second voltage.

16. The system of claim 1 , wherein

the controller comprises a second line connecting the first power supply and the power supply terminal of the first processor, and another line connecting the first connector and the power supply terminal of the first processor, and

the first processor is configured to be operated by each of power supplied from the first power supply via the second line and power supplied from the power supply device via the another line.

17. The system according to claim 16 , wherein

in an unconnected state in which the first connector is not connected to the second connector, the first processor is operated by power supplied from the first power supply via the second line, and

in a connected state in which the first connector is connected to the second connector, the first processor is operated by power supplied from the power supply device via the another line.

18. The system according to claim 1 , wherein

during charging of the first power supply by power supplied from the power supply device, a voltage applied to the power supply terminal of one of the first processor and the second processor that controls the charging is higher than a voltage applied to the power supply terminal of the other processor.

19. An aerosol generation system comprising:

a first power supply;

a first connector;

a first processor configured to perform energization control of a heater which is used to heat an aerosol source;

a second power supply;

a second connector which is connected to the first connector at the time of charging of the first power supply;

a second processor configured to perform control of power supply from the second power supply to a controller via the second connector;

a linear regulator on a line connecting the second power supply and a power supply terminal of the second processor; and

a DC/DC converter configured to convert a voltage supplied from the second power supply and output the converted voltage to the second connector, wherein

a first voltage applied to a power supply terminal of the first processor such that the first processor is capable of performing the energization control and a second voltage applied to a power supply terminal of the second processor such that the second processor is capable of performing the energization control are different from each other, and

the DC/DC converter is not connected to the second power supply via the linear regulator.
