Description

Aerosol-generating article having a filter with a plurality of holes {AEROSOL GENERATING ARTICLE HAVING A FILTER WITH HOLES}

The embodiment relates to an aerosol-generating article having a filter having a plurality of holes.

In recent years, there has been an increasing demand for alternative methods to overcome the disadvantages of regular cigarettes. For example, there is an increasing demand for a method in which aerosol is generated by heating the aerosol-generating material in the cigarette, rather than a method of generating aerosol by burning a cigarette.

However, various types of additives or flavoring substances are included to meet the needs of users. Various research is required to improve the aromatic properties of these flavoring substances when heated to satisfy users' preferences.

Figure 1 is a diagram schematically showing an aerosol-generating article according to the prior art.

The aerosol-generating article according to the prior art is located on the upstream side of the aerosol medium filter unit 10 and the aerosol medium filter unit 11 containing dried fruit or dried natural materials, and the upstream filter unit 20 consists of a filter body. ), located on the downstream side with respect to the aerosol medium filter unit 10, and includes a downstream filter unit 30 made of a filter body.

In a state in which the upstream filter unit 20, the aerosol medium filter unit 10, and the downstream filter unit 30 are sequentially stacked, the cigarette paper 40 wraps them to maintain the shape of the aerosol-generating article.

At this time, the coating film 14 is formed on the cigarette paper 40 on a portion surrounding the aerosol media filter portion 10 or on a portion surrounding the liquid filter portion 12. The vegetable medium 12 provided in the aerosol medium filter unit 10 has at least one of the following shapes: sawdust, chips, wood sphere, panel type, and stick shape.

The upstream and downstream filter units 20 and 30 may be made of CA filters, pulp, cotton wicks, and ceramic filters, and may be made of cylindrical or tube-shaped filter bodies. However, there was a problem that the flavor component contained in the aerosol generated in the aerosol medium filter unit 10 was absorbed into the filter as it passed through the downstream filter unit 30 right before being inhaled into the mouth, preventing the user from fully enjoying the scent.

Therefore, there is a need to develop a filter that prevents the outflow of the medium contained in the aerosol medium filter unit 10 and allows the user to sufficiently feel the scent.
