Abstract

Provided is an aerosol generating device including: a heater heating an aerosol generating material by power supplied; a battery storing power to be supplied to the heater; and a controller controlling power supply to the heater and power supply to the battery, wherein, the controller monitors a heating state of the heater when the aerosol generating device is electrically connected to an external power supply source; performs heating of the heater without charging of the battery by the external power supply source when the monitored heating state is determined to be a rapid heating state; and controls power supply to the heater and power supply to the battery to perform charging of the battery and heating of the heater together by the external power supply source when the monitored heating state is determined not to be the rapid heating state.

Claims (19)

1. An aerosol generating device comprising:

a heater heating an aerosol generating material by power supplied;

a battery storing power to be supplied to the heater;

a terminal providing an electrical connection with an external power supply source; and

a controller configured to:

when the aerosol generating device is electrically connected to the external power supply source through the terminal, monitor a heating state of the heater; and

control power supply to the heater based on the monitored heating state of the heater.

2. The aerosol generating device of claim 1 , wherein the controller is further configured to:

monitor the heating state of the heater as a signal input by a user is detected, and

when the signal is not detected, supply power to the battery.

3. The aerosol generating device of claim 1 , further comprising a charger IC for supplying the battery and the heater with power supplied from the external power supply source,

wherein the controller is further configured to, based on the monitored heating state of the heater, control the charger IC to control the power supply to the heater.

4. The aerosol generating device of claim 3 , wherein the controller is further configured to:

when the monitored heating state of the heater is a rapid heating state, control the charger IC so that power supplied from the external power supply source is supplied only to the heater,

when the monitored heating state of the heater is a non-rapid heating state, control the charger IC so that a part of power supplied from the external power supply source is supplied to the battery and other part of power supplied from the external power supply source is supplied to the heater.

5. The aerosol generating device of claim 1 , wherein the heating state of the heater comprises a rapid heating state and a non-rapid heating state.

6. The aerosol generating device of claim 5 , wherein the rapid heating state is a heating state in which the heater is supplied with power higher than or equal to reference power.

7. The aerosol generating device of claim 5 , wherein the rapid heating state is a heating state in which the heater is supplied with a current higher than or equal to a reference current.

8. The aerosol generating device of claim 5 , wherein the rapid heating state is a heating state in which a change in temperature of the heater is greater than or equal to a reference change.
