Abstract

An aerosol generation system includes a tobacco medium accommodation portion and a moisturizer accommodation portion located at an upstream end or a downstream end of the tobacco medium accommodation portion. In addition, an aerosol generation system includes an aerosol generation device including an elongated cavity for accommodating the cigarette, a first heater for heating the tobacco medium accommodation portion, and a second heater for heating the moisturizer accommodation portion.

First claim

1 . An aerosol generation system comprising:
a cigarette including:
a tobacco medium accommodation portion; and
a moisturizer accommodation portion located at an upstream end or a downstream end of the tobacco medium accommodation portion; and
an aerosol generation device including:
an elongated cavity configured to accommodate the cigarette;
a first heater configured to heat the tobacco medium accommodation portion; and
a second heater configured to heat the moisturizer accommodation portion.

2 . The aerosol generation system of claim 1 , wherein the moisturizer accommodation portion has one of a porous matrix structure, a tube structure, a paper tube structure a cavity structure, and a honeycomb structure.

3 . The aerosol generation system of claim 1 , wherein the moisturizer accommodation portion is located at the upstream end of the tobacco medium accommodation portion.

4 . The aerosol generation system of claim 2 , wherein moisturizer is impregnated in the moisturizer accommodation portion having one of the porous matrix structure, the tube structure, and the honeycomb structure, or coated on the moisturizer accommodation portion having one of the paper tube structure and the cavity structure is coated with the moisturizer.

5 . The aerosol generation system of claim 1 , wherein
the moisturizer accommodation portion is located at a downstream end of the tobacco medium accommodation portion, and the second heater has a cylindrical structure arranged to surround at least part of the moisturizer accommodation portion, or the moisturizer accommodation portion is located at the upstream end of the tobacco medium accommodation portion, and the second heater has one of a cylindrical structure arranged to surround at least part of the moisturizer accommodation portion, a planar structure arranged to be located at an upstream end of the cigarette, an elongated structure arranged to be inserted into the moisturizer accommodation portion, and a structure formed by a combination thereof.

6 . The aerosol generation system of claim 1 , wherein the first heater operates to heat the tobacco medium accommodation portion in a first temperature range so that nicotine contained in the tobacco medium accommodation portion is aerosolized, and
wherein the second heater operates to heat the moisturizer accommodation portion in a second temperature range higher than the first temperature range.

7 . The aerosol generation system of claim 1 , wherein the moisturizer accommodation portion is wrapped by aluminum foil located inside cigarette paper.

8 . An aerosol generation device comprising:
an elongated cavity configured to accommodate a cigarette; a first heater configured to heat a tobacco medium accommodation portion of the cigarette; and a second heater configured to heat a moisturizer accommodation portion of the cigarette.

9 . The aerosol generation device of claim 8 , wherein
the moisturizer accommodation portion is located at a downstream end of the tobacco medium accommodation portion, and the second heater has a cylindrical structure arranged to surround at least part of the moisturizer accommodation portion, or the moisturizer accommodation portion is located at an upstream end of the tobacco medium accommodation portion, and the second heater has one of a cylindrical structure arranged to surround at least part of the moisturizer accommodation portion, a planar structure arranged to be located at an upstream end of the cigarette, an elongated structure arranged to be inserted into the moisturizer accommodation portion, and a structure formed by a combination thereof.

10 . The aerosol generation device of claim 8 , wherein the first heater operates to heat the tobacco medium accommodation portion in a first temperature range so that nicotine contained in the tobacco medium accommodation portion is aerosolized, and
wherein the second heater operates to heat the moisturizer accommodation portion in a second temperature range higher than the first temperature range.
