Abstract

A non-heating aerosol generating article includes a tobacco medium filling at least one of a cellulose acetate filter or a paper filter, the tobacco medium includes granules including tobacco powder, and a pH adjusting aqueous solution including a pH adjuster and moisture, and the tobacco medium includes 8 wt % to 9 wt % of moisture with respect to a dry weight of the tobacco medium.

First claim

1 . A non-heating aerosol generating article comprising:
a tobacco medium filling at least one of a cellulose acetate filter or a paper filter, wherein the tobacco medium comprises granules comprising tobacco powder; and a pH adjusting aqueous solution comprising a pH adjuster and moisture, and the tobacco medium comprises 8 wt % to 9 wt % of moisture with respect to a dry weight of the tobacco medium.

2 . The non-heating aerosol generating article of claim 1 , wherein a pH of the tobacco medium is in a range of 8.7 to 8.9.

3 . The non-heating aerosol generating article of claim 1 , wherein the pH adjuster includes at least one of potassium carbonate (K 2 CO 3 ), sodium bicarbonate (NaHCO 3 ), or a mixture thereof.

4 . The non-heating aerosol generating article of claim 1 , wherein a particle diameter of the tobacco medium is 0.1 mm to 1.2 mm.

5 . The non-heating aerosol generating article of claim 1 , wherein a particle diameter of the tobacco medium is 0.3 mm to 0.6 mm.

6 . The non-heating aerosol generating article of claim 1 , wherein the tobacco medium is formed by spraying the pH adjusting aqueous solution onto the granules and then drying the granules.

7 . The non-heating aerosol generating article of claim 6 , wherein the pH adjusting aqueous solution includes 9 wt % to 11 wt % of a pH adjuster and 17 wt % to 23 wt % of moisture with respect a total weight of the granules.

8 . The non-heating aerosol generating article of claim 1 , further comprising: a front end portion; a medium portion disposed downstream of the front end portion and including the tobacco medium; and a filter portion disposed downstream of the medium portion and including a filter element.

9 . The non-heating aerosol generating article of claim 1 , wherein
the cellulose acetate filter includes a plurality of cellulose acetate tows, and the tobacco medium fills between the plurality of cellulose acetate tows.

10 . The non-heating aerosol generating article of claim 1 , wherein
the paper filter is included in a rolled form, and the tobacco medium fills between a paper of the paper filter in the rolled form and layers of the paper.

11 . The non-heating aerosol generating article of claim 8 , wherein the medium portion is filled with 2 mg/mm to 8 mg/mm of the tobacco medium.

12 . An aerosol generating system comprising:
a non-heating aerosol generating article of claim 1 ; and an aerosol generating device comprising an accommodation space accommodating the aerosol generating article and a cartridge comprising an aerosol generating material.

13 . The aerosol generating system of claim 12 , wherein the aerosol generating device includes a heating portion configured to heat the aerosol generating material included in the cartridge.

14 . The aerosol generating system of claim 13 , wherein
the aerosol generating material included in the cartridge is heated to generate an aerosol, and the aerosol is configured to be transferred to the aerosol generating article.
