Aerosol generating device and an operation method thereof

1. An aerosol generating device comprising:

a main body including a controller and a battery; and

a cartridge detachably coupled to the main body,

wherein the controller periodically detects whether the cartridge is coupled to the main body while the aerosol generating device operates in a first mode, determines whether a preset period of time has elapsed based on the cartridge being determined to have been separated from the main body, and switches the aerosol generating device from the first mode to a second mode based on whether the cartridge is coupled to the main body before the preset period of time elapses.

2. The aerosol generating device of claim 1 , wherein the controller performs a preheating operation by supplying power to the cartridge based on the cartridge being coupled to the main body before the preset period of time elapses.

3. The aerosol generating device of claim 1 , wherein the controller switches the aerosol generating device from the first mode to the second mode based on the cartridge being not coupled to the main body before the preset period of time elapses.

4. The aerosol generating device of claim 3 , wherein the controller does not perform periodic detection of whether the cartridge is coupled to the main body when the aerosol generation device is operating in the second mode.

5. The aerosol generating device of claim 1 , further comprising a user interface including at least one of a display for outputting visual information, a motor for outputting haptic information, and a speaker for outputting sound information,

wherein the controller outputs a notification through the user interface when the cartridge has been separated from the main body.

6. The aerosol generating device of claim 1 , wherein the preset period of time is set in a range of 10 seconds to 45 seconds.

7. The aerosol generating device of claim 2 , further comprising a puff detecting sensor for detecting a user's puff,

wherein the controller performs a heating operation by increasing the power supplied to the cartridge based on the user's puff being detected by the puff detecting sensor.

8. The aerosol generating device of claim 1 , further comprising:

a slider movably coupled to the main body such that the slider moves between a first position and a second position; and

a position change detecting sensor for detecting movement of the slider, and

the controller switches from the second mode to the first mode based on the slider moving from the first position to the second position and switches from the first mode to the second mode based on the slider moving from the second position to the first position.

9. The aerosol generating device of claim 8 , wherein minimal power is consumed to drive the position change detecting sensor when aerosol generating device operates in the second mode.

10. The aerosol generating device of claim 8 , wherein

an end of a mouthpiece coupled to the cartridge is covered by the slider when the slider is at the first position, and

the end of the mouthpiece is exposed to outside when the slider is at the second position.

11. A operation method of an aerosol generating device including a main body and a cartridge detachably coupled to the main body, the method comprising:

periodically detecting whether the cartridge is coupled to the main body while the aerosol generating device is operating in a first mode;

determining whether a preset period of time has elapsed based on the cartridge being determined to have been separated from the main body; and

switching from the first mode to a second mode based on whether the cartridge is coupled to the main body before the preset period of time elapses.

12. A computer-readable recording medium in which one or more programs including instructions for executing the method of claim 11 are recorded.
