Abstract

As an embodiment of the present disclosure, there is disclosed an aerosol generating device including: a heater configured to generate an aerosol by heating an aerosol generating substrate; a storage unit configured to store information regarding a first time period and a second time period for controlling a temperature of the heater; and a controller configured to control power supplied to the heater, wherein the controller, when the first time period time elapses after the temperature of the heater reaches the first target temperature, changes the temperature of the heater to a second target temperature for the second time period, and the sum of the first time period and the second time period is a time period in a preset change.

Claims (16)

1. An aerosol generating device comprising:

a heater configured to generate an aerosol by heating an aerosol generating substrate;

a storage unit configured to store information regarding a first time period, a second time period and third time period for controlling a temperature of the heater;

a controller configured to control power supplied to the heater,

wherein the controller,

when the temperature of the heater reaches the first target temperature and the first time period elapses, changes the temperature of the heater to the second target temperature over the third time period and maintains the second target temperature for the second time period, and

the sum of the first time period, the second time period, and the third time period is a time period in a preset range.

2. The aerosol generating device of claim 1 , wherein a length of the first time period is greater than a length of the second time period.

3. The aerosol generating device of claim 1 , wherein the first target temperature is higher than the second target temperature.

4. The aerosol generating device of claim 1 , wherein the sum of the first time period and the second time period is greater than four minutes and less than five minutes.

5. The aerosol generating device of claim 1 , wherein the sum of the first time period and the second time period is greater than three minutes and less than four minutes.

6. The aerosol generating device of claim 1 , a proportion of the length of the first time period to the length of the second time period is a constant value.

7. The aerosol generating device of claim 1 , wherein the heater is an induction heating type heater including an electrically conductive coil.

8. The aerosol generating device of claim 1 , wherein the controller warm up the heater to reach the temperature of the heater to the first target temperature.

9. The aerosol generating device of claim 1 , wherein the controller controls the temperature of the heater so that the amount of migration of nicotine increases in the first period and the amount of migration of nicotine decreases in the second period after the first period.

10. The aerosol generating device of claim 1 , wherein the controller controls the temperature of the heater so that the amount of migration of glycerin increases in the first period and the amount of migration of glycerin decreases in the second period after the first period.
