Abstract

Provided is a method of controlling a temperature of a heater included in an aerosol generation device according to a type of cigarette. The method includes receiving temperature profiles of different types of cigarette from a user terminal; sensing a cigarette coupled to the heater after receiving the temperature profiles; identifying a type of the sensed cigarette; selecting a temperature profile corresponding to the identified type from among the temperature profiles; and controlling power supplied from a battery to the heater according to the selected temperature profile.

Claims (20)

1. A method of controlling a temperature of a heater included in an aerosol generation device, the method comprising:

receiving temperature profiles of different types of cigarette from a user terminal before a cigarette is coupled to the heater;

sensing the cigarette coupled to the heater after receiving the temperature profiles, when a distance between the heater and the cigarette becomes less than a predetermined distance that enables the aerosol generation device to detect an identification code on the cigarette;

identifying a type of the sensed cigarette by detecting the identification code on the cigarette;

selecting a temperature profile corresponding to the identified type from among the temperature profiles of different types of cigarette that are stored in the aerosol generation device;

in response to a user input selecting a temperature profile that is different from the selected temperature profile being received, controlling power supplied from a battery to the heater according to the user input; and

in response to the user input not being received, controlling the power supplied from the battery to the heater to cause the temperature of the heater to match a variable temperature value according to the selected temperature profile.

2. The method of claim 1 , wherein the temperature profiles of different types of cigarette are received by the user terminal from a cigarette database for storing the temperature profiles of different types of cigarette.

3. The method of claim 1 , wherein the temperature profiles of different types of cigarette received from the user terminal are generated based on information input through an input device of the user terminal.

4. The method of claim 3 , wherein the information is input by recognizing one of quick reference (QR) code, bar code, and case code that are attached to a cigarette case.

5. The method of claim 1 , wherein the sensing includes sensing the coupling of the cigarette to the heater according to a result of recognizing an optical sticker that is attached to the cigarette.

6. The method of claim 1 , wherein the controlling of the power according to the selected temperature profile comprises:

controlling a pulse width modulator based on the selected temperature profile to supply the power to the heater so that the temperature of the heater varies over time according to the selected temperature profile.

7. A method of controlling a temperature of a heater included in an aerosol generation device, the method comprising:

sensing coupling of a cigarette to the heater;

identifying a type of the cigarette;

in response to sensing the coupling of the cigarette to the heater when a distance between the heater and the cigarette becomes less than a predetermined distance that enables the aerosol generation device to detect an identification code on the cigarette, identifying the type of the cigarette by detecting the identification code on the cigarette, and acquiring temperature profiles of different types of cigarette from a storage device for storing the temperature profiles of different types of cigarette, and identifying a temperature profile corresponding to the type of the cigarette, among the temperature profiles of different types of cigarette;

in response to a user input selecting a temperature profile that is different from the selected temperature profile being received, controlling the temperature of the heater according to the user input; and

in response to the user input not being received, controlling the temperature of the heater to vary over time according to the temperature profile corresponding to the type of the cigarette.

8. The method of claim 7 , wherein the identifying the type of the cigarette, includes identifying the type of the cigarette using a radio frequency identification (RFID) reader sensing an RFID tag attached to the cigarette.
