Abstract

An aerosol generating device includes a cartridge configured to store an aerosol generating material, a main body to which the cartridge is detachably coupled, a first heater configured to heat a cigarette inserted into the aerosol generating device, a second heater configured to heat an aerosol generating material, and a processor configured to individually control the first heater and the second heater so that the aerosol generating device operates in one of a smokeless mode in which visible smoke is not generated and a smoke mode in which visible smoke is generated.

First claim

The invention claimed is:

1 . An aerosol generating device comprising:
a main body to which a cartridge is detachably coupled, wherein the main body comprises:
a first heater configured to heat a cigarette inserted into the aerosol generating device;
a second heater configured to heat an aerosol generating material stored in the cartridge; and
a processor configured to:
individually control the first heater and the second heater so that the aerosol generating device operates in either a smokeless mode in which only the first heater is operated and visible smoke is not generated, or a smoke mode in which visible smoke is generated; and
control a battery to supply power to both the first heater and the second heater in the smoke mode.

2 . The aerosol generating device of claim 1 , wherein the processor is further configured to control the first heater so that the cigarette is heated to a temperature less than a first temperature, the first temperature being a temperature at which visible smoke is generated.

3 . The aerosol generating device of claim 1 , wherein the processor is further configured to control the second heater so that the aerosol generating material is heated to a temperature equal to or higher than an evaporation point.

4 . The aerosol generating device of claim 1 , wherein, in the smoke mode, the processor is further configured to control the first heater so that the cigarette is heated to a temperature equal to or higher than a first temperature, the first temperature being a temperature at which visible smoke is generated.

5 . The aerosol generating device of claim 1 , wherein, in the smoke mode, the processor is further configured to control the second heater so that the aerosol generating material is heated to a temperature equal to or higher than an evaporation point.

6 . The aerosol generating device of claim 1 , further comprising:
a user interface configured to receive a first user input for selecting one of the smokeless mode and the smoke mode, wherein the processor is further configured to control the first heater and the second heater according to a previously-selected mode, in response to a second user input for generating an aerosol.

7 . The aerosol generating device of claim 6 , wherein,
when the smokeless mode is selected, the user interface is configured to receive a third user input for selecting one from among a plurality of temperature profiles within a first temperature range with respect to the first heater, when the smoke mode is selected, the user interface is further configured to receive a fourth user input for selecting one from among a plurality of temperature profiles within a second temperature range with respect to the first heater and one from among a plurality of temperature profiles within a third temperature range with respect to the second heater, and the processor is further configured to control the first heater and the second heater according to the selected at least one temperature profile.

8 . The aerosol generating device of claim 6 ,
wherein the main body comprises an internal space with a sensor configured to detect insertion of the cigarette, and wherein the processor is further configured to detect insertion of the cigarette based on a signal generated by the sensor, and when insertion of the cigarette is detected, control the first heater and the second heater according to a previously-selected mode.

9 . The aerosol generating device of claim 1 , wherein the processor is further configured to control an amount of nicotine provided to the user, by individually controlling the first heater and the second heater.

10 . An operating method of an aerosol generating device, comprising:
receiving a first user input for selecting either a smokeless mode in which visible smoke is not generated from the aerosol generating device or a smoke mode in which visible smoke is generated from the aerosol generating device; detecting whether a cigarette is inserted into the aerosol generating device; and when insertion of the cigarette is detected, individually controlling a first heater and a second heater based on a previously-selected mode, wherein in the smokeless mode, only the first heater is operated, wherein the first heater heats the cigarette, and the second heater heats an aerosol generating material stored in a cartridge, and wherein power is supplied, by a battery, to both the first heater and the second heater in the smoke mode.

11 . The operating method of claim 10 , wherein the controlling comprises:
operating only the first heater among the first heater and the second heater when the smokeless mode is selected.

12 . The operating method of claim 10 , wherein the receiving of the first user input comprises:
when the smokeless mode is selected, receiving a second user input for selecting one from among a plurality of temperature profiles within a first temperature range with respect to the first heater; and when the smoke mode is selected, receiving a third user input for selecting one from among a plurality of temperature profiles within a second temperature range with respect to the first heater and one from among a plurality of temperature profiles within a third temperature range with respect to the second heater, and wherein the controlling comprises controlling the first heater and the second heater according to the selected at least one temperature profile.
