Aerosol generating article and aerosol generating device comprising same
The present invention provides an aerosol-generating article including a first aerosol-generating substrate portion, a second aerosol-generating substrate portion, and a filter portion containing nicotine, and an aerosol-generating device comprising the same, wherein the second aerosol-generating substrate portion includes an absorber impregnated with a liquid aerosol-generating composition.
1. An aerosol-generating article comprising:
a nicotine-containing first aerosol-generating substrate portion;
a second aerosol-generating substrate portion; and
a filter portion,
wherein the second aerosol-generating substrate portion includes an absorber impregnated with a liquid aerosol-generating composition, and
wherein a weight ratio of glycerin contained in the nicotine-containing first aerosol-generating substrate portion to glycerin contained in the second aerosol-generating substrate portion is 1 to 6:4 to 9.
2. The aerosol-generating article of claim 1 , wherein the nicotine-containing first aerosol-generating substrate portion contains an aerosol-generating composition, and the aerosol-generating composition contains a tobacco material, an additive in an amount of 0.2 to 50 parts by weight based on 100 parts by weight of the tobacco material, and glycerin in an amount of 0 to 400 parts by weight based on 100 parts by weight of the tobacco material.
3. The aerosol-generating article of claim 1 , wherein the liquid aerosol-generating composition contains glycerin in an amount of 5 to 60 parts by weight, propylene glycol (PG) in an amount of 0 to 15 parts by weight, an additive in an amount of 5 to 40 parts by weight, and water in an amount of 0 to 10 parts by weight.
4. The aerosol-generating article of claim 1 , wherein the second aerosol-generating substrate portion is positioned in front of the nicotine-containing first aerosol-generating substrate portion, behind the nicotine-containing first aerosol-generating substrate portion, or at front and back of the nicotine-containing first aerosol-generating substrate portion.
5. The aerosol-generating article of claim 1 , wherein the absorber impregnated with the liquid aerosol-generating composition is selected from the group consisting of paper, cotton, and silica.
6. The aerosol-generating article of claim 5 , wherein the absorber impregnated with the liquid aerosol-generating composition is a rolled form of paper in which stripe-shaped wrinkles or sheaths are formed by crimping the paper.
7. An aerosol-generating device comprising:
the aerosol-generating article of claim 1 , and
an aerosol generator including an aerosol-generating article receiving groove and a heater member provided under the aerosol-generating article receiving groove.
8. The aerosol-generating device of claim 7 , wherein the heater member is configured to simultaneously heat the nicotine-containing first aerosol-generating substrate portion and the second aerosol-generating substrate portion.
