{UNHEATED AEROSOL GENERATING ARTICLE COMPRISING ACIDIC AQUEOUS SOLUTION}

The present disclosure relates to an unheated aerosol-generating article comprising an acidic aqueous solution.

In recent years there has been an increasing demand for alternative methods that overcome the shortcomings of common aerosol-generating articles. For example, there is a growing need for products that provide nicotine in the form of chewing or ingestion of an aerosol-generating article, rather than a method of generating an aerosol by burning or heating the aerosol-generating article.

In particular, snus (snus) or snuff (snuff) products, unlike general cigarettes, are cigarette widely used in the United States, Europe, Asia, etc. because there is no carcinogen such as tar generated in the combustion process. If you work in a situation where you cannot smoke for a long time, Snoo or Snoop products are being used as a substitute for regular cigarettes because they can supply nicotine slowly for a long time.

The housing 110 may include a material having rigidity or elasticity so that the exterior has a certain shape. For example, the housing 110 may include gum, carrageenan, gelatin, or an agar material. However, the present disclosure is not necessarily limited to the above-mentioned materials, and well-known materials suitable for maintaining the external shape of the housing 110 uniformly may be utilized.

The first chamber 120 may include an acidic aqueous solution. Specifically, the first chamber 120 may include an aqueous solution containing a strong acid or a weak acid, for example, the acidic aqueous solution may have an acidity of pH 2 to 6.5. As a specific example, the first chamber 120 is hydrochloric acid (HCl), perchloric acid (HClO ₄ ), nitric acid (HNO ₃ ), sulfuric acid (H ₂ SO ₄ ), carbonic acid (H ₂ CO ₃ ), or acetic acid (CH ₃ COOH) ), and preferably, carbonic acid (H ₂ CO ₃ ), or acetic acid (CH ₃ COOH). However, the present disclosure is not necessarily limited to the above, and any known acidic aqueous solution that reacts with sodium hydrogen carbonate powder to generate carbon dioxide gas may be used without limitation.

The first chamber 120 may sufficiently contain the above-described acidic aqueous solution. The entire first chamber 120 may be filled with the acidic aqueous solution, only a part of the first chamber 120 may be filled with the acidic aqueous solution, and a part of the first chamber 120 may be empty.

Accordingly, the user can inhale the aerosol (A). Since the above-described chemical reaction occurs at a relatively appropriate rate, the injection of the aerosol (A) may occur at a rate corresponding to the rate at which the carbon dioxide gas (G) presses the second separation membrane 160 .

In addition, by adjusting the size of the liquid composition storage pack disposed in the third chamber 140 or the third chamber 140 of the aerosol-generating article 100, the liquid composition or liquid nicotine per one aerosol-generating article 100 is contained.
