Abstract

Claims (29)

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

displaying, by a user terminal, a plurality of cigarette types through a display unit included in the user terminal;

determining, by the user terminal, a cigarette type selected from the plurality of cigarette types based on information input through an input device included in the user terminal; and

transmitting, by the user terminal, the determined cigarette type to the aerosol generation device,

wherein, when a cigarette is coupled to the heater of the aerosol generation device, a temperature of the heater is controlled according to a temperature profile corresponding to the transmitted cigarette type regardless of a cigarette type of the coupled cigarette,

wherein the cigarette is divided into a first portion including an aerosol generating material and a second portion including a filter, and

wherein the aerosol generating material varies depending on the cigarette type, and the temperature profile defines the temperature of the heater over time for vaporizing the aerosol-generating material.

2 . The method of claim 1 , further comprising setting up a local area network with the aerosol generation device,

wherein the local area network comprises at least one of Bluetooth communication, near-field communication (NFC) communication, and Wi-Fi Direct communication.

3 . The method of claim 1 , wherein the user terminal communicates with an external server to receive a plurality of temperature profiles corresponding to the plurality of cigarette types stored in a cigarette database.

4 . The method of claim 1 , wherein the input device comprises at least one of a soft button, a hard button and a touch panel.

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

receiving a cigarette type among a plurality of cigarette types from a user terminal connected through a local area network; and,

when a cigarette is coupled to the heater of the aerosol generation device, controlling a temperature of the heater according to a temperature profile corresponding to the received cigarette type regardless of a cigarette type of the coupled cigarette,

wherein the user terminal is configured to display the plurality of cigarette types through a display unit of the user terminal and determine the cigarette type based on information input through an input device included in the user terminal,

wherein the cigarette is divided into a first portion including an aerosol generating material and a second portion including a filter, and

wherein the aerosol generating material varies depending on the cigarette type, and the temperature profile defines the temperature of the heater over time for vaporizing the aerosol-generating material.

6 . The method of claim 5 , wherein the heater comprises an electrically conductive coil and a susceptor heated by a magnetic field induced by the electrically conductive coil.

7 . An apparatus for controlling a heater of an aerosol generation device, the apparatus comprising:

a display unit;

an input device;

a communication unit communicating with the aerosol generation device by using a local area network; and

a controller configured to display a plurality of cigarette types through the display unit, determine a cigarette type among the plurality of cigarette types based on information input through the input device, and transmit the determined cigarette type to the aerosol generation device through the communication unit,

wherein, when a cigarette is coupled to the heater of the aerosol generation device, a temperature of the heater is controlled according to a temperature profile corresponding to the transmitted cigarette type regardless of a cigarette type of the coupled cigarette,

wherein the cigarette is divided into a first portion including an aerosol generating material and a second portion including a filter, and

wherein the aerosol generating material varies depending on the cigarette type, and the temperature profile defines the temperature of the heater over time for vaporizing the aerosol-generating material.

8 . The apparatus of claim 7 , wherein the local area network comprises at least one of Bluetooth communication, near-field communication (NFC) communication, and Wi-Fi Direct communication.

9 . The apparatus of claim 7 , wherein the controller is configured to set up the local area network with the aerosol generation device.

10 . The apparatus of claim 7 , wherein the input device comprises at least one of a soft button, a hard button and a touch panel.
