Abstract

Claims (41)

1. An aerosol generating system comprising:

a holder configured to generate aerosol by heating a cigarette;

a cradle having an inner space for accommodating the holder, wherein the holder is moveable in the inner space of the cradle;

at least one sensor configured to sense variation in a position of the holder in the inner space of the cradle; and

a controller configured to make a prediction about insertion of the cigarette into the holder based on sensing of the sensor, and start first preheating of a heater of the holder before the cigarette is inserted in the holder based on a result of the prediction, and start second preheating of the heater of the holder after the cigarette is completely inserted in the holder,

wherein the first preheating and the second preheating have different target temperature profiles.

2. The aerosol generating system of claim 1 , wherein

the sensor senses separation of the holder from the inner space of the cradle, and the controller is configured to start the first preheating based on the separation of the holder from the inner space of the cradle.

3. The aerosol generating system of claim 1 , further comprising

a power supply device,

wherein the controller is configured to start the first preheating by using power supplied from the power supply device.

4. The aerosol generating system of claim 1 , further comprising a power supply device disposed in the cradle,

wherein the controller is configured to start the first preheating by using power supplied from the power supply device.

5. The aerosol generating system of claim 1 , wherein

the controller is configured to control the first preheating within a preset temperature range.

6. The aerosol generating system of claim 5 , wherein

the controller is configured to control the first preheating within a range of 100° C. to 350° C.

7. The aerosol generating system of claim 1 , wherein

the controller is configured to control the first preheating to heat the heater for a preset time period.

8. The aerosol generating system of claim 7 , wherein

the controller is configured to control the first preheating to heat the heater for 1 to 3 seconds.

9. The aerosol generating system of claim 1 , wherein

the holder comprises at least one input device for controlling functions of the holder, and

the controller is configured to start the first preheating in response to receiving an input through the at least one input device.

10. An aerosol generating system comprising:

a holder configured to generate aerosol by heating a cigarette;

a cradle having an inner space for accommodating the holder, wherein the holder is moveable in the inner space of the cradle;

a controller configured to make a prediction about insertion of the cigarette into the holder, and start preheating a heater of the holder before the cigarette is inserted in the holder, based on a result of the prediction; and

a sensor configured to sense whether the cigarette is inserted into the holder,

wherein the controller preheats the heater until the cigarette contacts a predetermined portion of the heater based on a sensing result of the sensor.

11. A method of generating aerosol by heating a cigarette in an aerosol generating system, the method comprising:

making a prediction about insertion of the cigarette into a holder based on variation in a position of the holder that is accommodated in an inner space of a cradle;

starting first preheating of a heater of the holder before the cigarette is inserted in the holder based on a result of the prediction, and

starting second preheating of the heater of the holder after the cigarette is completely inserted in the holder,

wherein the first preheating and the second preheating have different target temperature profiles.

12. The method of claim 11 , wherein the making the prediction comprises:

sensing variation in a position of the holder after the holder is inserted into an inner space of a cradle; and

predicting the insertion of the cigarette into the holder based on a result of the sensing.

13. The method of claim 12 , wherein the sensing of the variation in the position of the holder comprises sensing tilting of the holder after the holder is inserted into the inner space of the cradle.

14. The method of claim 12 , wherein the sensing of the variation in the position of the holder comprises sensing separation of the holder from the inner space of the cradle.

15. A computer-readable recording medium having recorded thereon a program for performing the method of claim 11 on a computer.
