Abstract

Claims (28)

1. An aerosol generating system comprising:

a cigarette including a mouth piece and a substrate portion including a first segment and a second segment;

a heater configured to generate an aerosol by heating at least a portion of an aerosol generating substrate arranged in the first segment and the second segment;

a cigarette recognition sensor comprising:

a first sensor configured to detect the aerosol generating substrate arranged in the first segment in the cigarette by transmitting a first magnetic field signal of a first preset frequency and detecting a first signal reflected from the aerosol generating substrate of the first segment; and

a second sensor configured to detect the aerosol generating substrate arranged in the second segment in the cigarette by transmitting a second magnetic field signal of a second preset frequency and detecting a second signal reflected from the aerosol generating substrate of the second segment; and

a controller configured to:

identify a type of the cigarette based on a detection result of the first sensor and the second sensor, and

control power supplied to the heater such that the cigarette is heated according to a temperature profile corresponding to the identified type.

2. The aerosol generating system of claim 1 , wherein the first segment includes a first substrate providing a user with a first aerosol, and the second segment includes a second substrate providing the user with a second aerosol.

3. The aerosol generating system of claim 2 , wherein

the first substrate is related to an amount of nicotine transfer in the cigarette, and

the second substrate is related to an amount of glycerin transfer in the cigarette.

4. The aerosol generating system of claim 1 , wherein the heater comprises at least one of:

a contact-type heater configured to heat the aerosol generating substrate by contacting the aerosol generating substrate; and

a non-contact-type heater configured to heat the aerosol generating substrate without contacting the aerosol generating substrate, and arranged outside of wrapping paper surrounding the aerosol generating substrate.

5. The aerosol generating system of claim 1 , wherein

the cigarette recognition sensor includes a plurality of sensors, and

the controller is configured to identify different aerosol generating substrates based on detection results of the plurality of sensors.

6. An aerosol generating device comprising:

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

a cigarette recognition sensor comprising:

a first sensor configured to detect the aerosol generating substrate arranged in a first segment of a cigarette by transmitting a first magnetic field signal of a first preset frequency and detecting a first signal reflected from the aerosol generating substrate of the first segment; and

a second sensor configured to detect the aerosol generating substrate arranged in a second segment of the cigarette by transmitting a second magnetic field signal of a second preset frequency and detecting a second signal reflected from the aerosol generating substrate of the second segment; and

a controller configured to:

identify a type of the cigarette, based on a detection result of the first sensor and the second sensor, and

control power supplied to the heater such that the cigarette is heated according to a temperature profile corresponding to the identified type,

wherein the cigarette includes a mouth piece.
