Abstract

Discloses is a aerosol generating system including: an aerosol generation device configured to generate an aerosol by heating an aerosol generating material; and an external power supply device including a case, a charger receiving unit which is rotatably coupled to the case and configured to receive the aerosol generation device in a detachable manner such that the aerosol generation device is driven in one of a charging mode, a cleaning mode, a preheating mode, and a smoking mode while being received in the charger receiving unit.

First claim

What is claimed is:

1. A system for charging an aerosol generation device, the system comprising:
an aerosol generation device comprising a heater for generating heat by resistance when a current is applied to the heater, a power storage unit for supplying electric power to the heater, and a controller for controlling the heater; and
an external power supply device comprising a case, a charger receiving unit mounted rotatably on the case and configured to receive the aerosol generation device in a detachable and attachable manner, an auxiliary power storage device for storing electric power to be delivered to the aerosol generation device, and an auxiliary power supplying device for controlling the auxiliary power storage device to supply the electric power to the aerosol generation device,
wherein the aerosol generation device is driven in one mode from among a charging mode, a cleaning mode, a preheating mode, and a smoking mode, according to where the aerosol generation device is received in the charger receiving unit,
wherein the charger receiving unit is rotatable between a first position where the charger receiving unit is positioned parallel to a longitudinal direction of the case and a second position where the charger receiving unit is tilted with respect to the longitudinal direction of the case,
wherein the external power supply device further comprises a first magnetic body and a second magnetic body provided on the case, the first magnetic body and the second magnetic body being positioned on opposite sides of a rotation axis of the charger receiving unit, and
wherein the charger receiving unit comprises a third magnetic body facing one of the first magnetic body and the second magnetic body.

2. The system of claim 1 , wherein
a hole is formed to penetrate the charger receiving unit,
grooves corresponding to the hole is formed inside the case,
the charger receiving unit is coupled to the case by means of a hinge inserted into the hole and the grooves, and
the charger receiving unit is rotatable about the hinge with respect to the case.

3. The system of claim 1 , wherein
the charger receiving unit comprises a first charging terminal which is exposed to outside and electrically connected to the auxiliary power storage device and the auxiliary power supplying device, and
the aerosol generation device further comprises a second charging terminal that is connected to the first charging terminal when the aerosol generation device is inserted in the charger receiving unit such that electric power is supplied from the auxiliary power storage device to the aerosol generation device through the first charging terminal.

4. The system of claim 1 , wherein
the charger receiving unit further comprises a fourth magnetic body facing the other one of the first magnetic body and the second magnetic body.

5. The system of claim 4 , wherein
the charger receiving unit maintains the first position by attraction force between the third magnetic body and one of the first magnetic body and the second magnetic body, and maintains the second position by an attraction force between the fourth magnetic body and the other one of the first magnetic body and the second magnetic body.

6. The system of claim 4 , wherein
when the aerosol generation device is received in the charger receiving unit, the charger receiving unit aligns the aerosol generation device inside the charger receiving unit in such a manner that a distance between a centerline of the fourth magnetic body and the other one of the first magnetic body and the second magnetic body is minimized.

7. The system of claim 1 , wherein
the aerosol generation device further comprises a first button portion configured to receive a user's manipulation input to block or allow supply of the electric power from the power storage unit to the heater.

8. The system of claim 1 , wherein
the external power supply device further comprises a second button portion configured to receive a user's manipulation input to block or allow supply of the electric power from the auxiliary power storage device to the aerosol generation device.

9. The system of claim 7 , wherein
when the charger receiving unit, in which the aerosol generation device is received, is in the first position where the charger receiving unit is positioned parallel to a longitudinal direction of the case, the aerosol generation device is driven in the charging mode, and
when the aerosol generation device is driven in the charging mode, the electric power stored in the auxiliary power storage device is delivered to the power storage unit of the aerosol generation device.

10. The system of claim 8 , wherein
when the second button portion is manipulated while the charger receiving unit, in which the aerosol generation device is received, is in the first position where the charger receiving unit is positioned parallel to a longitudinal direction of the case, the aerosol generation device is driven in the cleaning mode, and
when the aerosol generation device is driven in the cleaning mode, the auxiliary power storage device activates the heater of the aerosol generation device.

11. The system of claim 8 , wherein
when the charger receiving unit, in which the aerosol generation device is received, is in the second position where the charger receiving unit is tilted with respect to a longitudinal direction of the case, the aerosol generation device is driven in one of the preheating mode and the smoking mode.

12. The system of claim 11 , wherein
when the second button portion is manipulated while the charger receiving unit, in which the aerosol generation device is received, is in the second position, the aerosol generation device is driven in the preheating mode, and
when the aerosol generation device is driven in the preheating mode, the auxiliary power supplying device raises a temperature of the heater to an operating temperature.

13. The system of claim 12 , wherein,
when the temperature of the heater is raised to the operating temperature, the aerosol generation device is driven in the smoking mode in which the temperature of the heater is maintained at the operating temperature.

14. The system of claim 1 , wherein
the charger receiving unit comprises a switching member protruding toward the auxiliary power supplying device,
the auxiliary power supplying device comprises a third button portion configured to be pressed by the switching member when the charger receiving unit is in the second position, and
when the third button portion is pressed, the auxiliary power supplying device supplies the electric power from the power storage unit to the heater of the aerosol generation device, thereby operating the heater.
