1 is a view showing an example of an aerosol-generating rod.

Referring to FIG. 1, the aerosol-generating rod 100 includes a medium part 110 and a filter part 120.

In FIG. 1, the filter unit 120 is illustrated as a single segment, but is not limited thereto. In other words, the filter unit 120 may be composed of a plurality of segments. For example, the filter unit 120 may include a first segment for cooling the aerosol and a second segment for filtering a predetermined component included in the aerosol. In addition, if necessary, the filter unit 120 may further include at least one segment that performs other functions.

The aerosol-generating rod 100 may be packaged by at least one wrapper 140. The wrapper 140 may have at least one hole through which external air flows or internal gas flows out. As an example, the aerosol-generating rod 100 may be packaged by one wrapper 140. As another example, the aerosol-generating rod 100 may be packaged overlapping by two or more wrappers 140. For example, the medium part 110 may be packaged by the first wrapper, and the filter part 120 may be packaged by the second wrapper. In addition, the medium portion 110 and the filter portion 120 packaged by individual wrappers are combined, and the entire aerosol-generating rod 100 may be repackaged by a third wrapper. If each of the medium section 110 or the filter section 120 is composed of a plurality of segments, each segment may be packaged by a separate wrapper. In addition, the entire aerosol-generating rod 100 in which segments packaged by individual wrappers are combined may be repackaged by another wrapper.

The medium 110 includes an aerosol-generating material. For example, the aerosol-generating material may include, but is not limited to, glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In addition, the medium 110 may contain other additives, such as flavors, wetting agents and / or organic acids. In addition, a flavoring liquid such as menthol or moisturizer may be added to the medium portion 110 by spraying the medium portion 110.

The medium 110 may be manufactured in various ways. For example, the medium portion 110 may be made of a sheet or may be made of strands. In addition, the medium section 110 may be made of cut tobacco cut into cuts. Also, the medium portion 110 may be surrounded by a heat-conducting material. For example, the heat-conducting material may be a metal foil such as aluminum foil, but is not limited thereto. For example, the heat-conducting material surrounding the medium portion 110 may evenly disperse heat transferred to the medium portion 110 to improve the thermal conductivity applied to the medium portion, thereby improving the taste of tobacco. . In addition, the heat-conducting material surrounding the medium portion 110 may function as a susceptor heated by an induction heater. At this time, although not shown in the drawing, the medium portion 110 may further include an additional susceptor in addition to the heat-conducting material surrounding the outside.

The filter unit 120 may be a cellulose acetate filter. Meanwhile, the shape of the filter unit 120 is not limited. For example, the filter unit 120 may be a cylindrical type rod or a tube type rod including a hollow inside. Also, the filter unit 120 may be a recessed type load. If the filter unit 120 is composed of a plurality of segments, at least one of the plurality of segments may be manufactured in a different shape.

The filter unit 120 may be manufactured to generate flavor. As an example, the flavourant may be sprayed onto the filter unit 120, or a separate fiber coated with the flavourant may be inserted into the filter unit 120.

Also, the filter unit 120 may include at least one capsule 130. Here, the capsule 130 may perform a function of generating flavor or a function of generating an aerosol. For example, the capsule 130 may be a structure in which a liquid containing a fragrance is wrapped with a film. Capsule 130 may have a spherical or cylindrical shape, but is not limited thereto.

If the filter unit 120 includes a segment for cooling the aerosol, the cooling segment may be made of a polymer material or a biodegradable polymer material. For example, the cooling segment may be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment may be made of a cellulose acetate filter with a plurality of perforations. However, the cooling segment is not limited to the above-described example, and may be applied without limitation as long as the aerosol can perform a cooling function.

Referring to FIG. 2, the aerosol-generating rod 100 may be composed of a medium part 110 and a filter part 120 connected to an upstream end of the medium part 110. The filter unit 120 may be composed of a plurality of filter segments including an upstream filter segment 150, a capsule filter segment 160, and a downstream filter segment 170. The capsule filter segment 160 may be composed of a hard capsule 180 that carries the functional material 190 in the inner space.

The hard capsule 180 constituting the capsule filter segment 160 may have a structure having both ends and an inner space in a hemispherical shape. The hard capsule 180 may carry the functional material 190 in the interior space. The functional material 190 is a solid material and may be formed in any one of spherical, fillet, and sheet forms.

The functional material 190 may include at least one of a flavor component, a cooling component, a moisturizing component, an adsorption component, and a tobacco component. The hard capsule 180 and the functional material 190 filled in the inner space of the hard capsule 180 will be described later in more detail with reference to FIG. 3.

The filter unit 120 may be formed in such a manner that both ends of the hard capsule 180 contact one end of the upstream filter segment 150 and the downstream filter segment 170. Since the hard capsule 180 constituting the capsule filter segment 160 carries the functional material 190, the capsule filter segment 160 is not provided with a structure for fixing the position of the functional material 190 separately therein. You can. Thus, the hard capsule 180 can itself constitute one capsule filter segment 160.

On the other hand, in order to fix the position of the functional material 190 (or the carrier that carries the functional material 190), the composite filter has separate structures at each of the front and rear ends of the cavity in which the functional material 190 is located. Needs to be.

The length of the composite filter is limited to a predetermined length or less in consideration of the entire length of the aerosol-generating rod 100, and structures positioned at the front end and rear end of the cavity cannot be manufactured at a predetermined length or less in the manufacturing process. Therefore, the length of the cavity in which the functional material 190 can be located can be very limited to a predetermined length or less. As a result, the size of the outer diameter of the functional material 190 accommodated in the limited length cavity may also be limited.

In addition, since the size of the outer diameter of the functional material 190 inserted into the cavity of the composite filter is limited to a predetermined length or less, when the structure located at the front end or rear end of the cavity is in the form of a tube containing hollow, the functional material ( 190) It is possible to move through the hollow in the structure during the manufacturing process of the filter or the user's inhalation process.

In addition, the functional material 190 may be deformed through impact or wear in the process of being inserted into the composite filter. In order to prevent the possibility of such deformation, the functional material 190 needs to have a certain strength or more. However, in the case of a specific functional material 190, it may be very difficult to manufacture to have a certain strength or more. In addition, the shape of the functional material 190 may be limited to a circular shape to minimize deformation of the shape due to wear.

On the contrary, when the capsule filter segment 160 is formed by filling the hard capsule 180 with the functional material 190, a structure for fixing the position of the functional material 190 separately inside the capsule filter segment 160 Since it may not be provided, the hard capsule 180 may constitute one capsule filter segment 160 by itself. The functional material 190 may have any size, shape, etc., as long as it can be supported only in the space inside the hard capsule 180. As a result, the functional material 190 carried in the hard capsule 180 may have various shapes such as a spherical shape, a fillet, or a sheet, regardless of the shape. In addition, since the functional material 190 may be supported by the size of the inner space of the hard capsule 180, the functional material 190 may have a larger outer diameter than when inserted into the composite filter.

In addition, since the outer diameter of the hard capsule 180 carrying the functional material 190 is the same as the outer diameter of the aerosol-generating rod 100, the hard capsule 180 is less likely to move to another filter segment. Therefore, the functional material 190 can be stably positioned in the aerosol-generating rod 100.

In addition, the hard capsule 180 constituting the capsule filter segment 160 at the time of manufacture of the filter unit 120 including the upstream filter segment 150, the capsule filter segment 160 and the downstream filter segment 170 is It can be preformed. In the manufacturing process of the filter unit 120, the functional material 190 is surrounded by the hard capsule 180, so it is less likely to be deformed by impact or abrasion. Therefore, the low-strength functional material 190 can also be applied to the aerosol-generating rod 100.

As such, as the hard capsule 180 itself constitutes the capsule filter segment 160 and the functional material 190 is supported in the inner space of the hard capsule 180, it can be supported only in the inner space of the hard capsule 180 If present, the type, size, shape, and strength of the functional material 190 may not be limited. Accordingly, the functional material 190 can be applied to the aerosol-generating rod 100 without limitation to the type, size, shape, etc. of the functional material 190.

On the other hand, referring to Figure 2, the filter unit 120 is located upstream of the capsule filter segment 160, the upstream filter segment 150 and the capsule filter segment 160 connected to one end of the capsule filter segment 160 Located downstream of the, it may further include a downstream filter segment 170 connected to the other end of the capsule filter segment (160).

The upstream filter segment 150 can be a cellulose acetate filter. For example, the upstream filter segment 150 may be in the form of a tube including a hollow inside, but is not limited thereto.

The downstream filter segment 170 can be made of cellulose acetate. For example, the downstream filter segment 170 may be made of a recess filter, but is not limited thereto.

The upstream filter segment 150 and the downstream filter segment 170 are spaced apart from each other by a predetermined distance, and a cavity may be formed between the upstream filter segment 150 and the downstream filter segment 170. In the formed cavity, a hard capsule 180 supporting the functional material 190 may be located.

At this time, both ends of the hard capsule 180 may contact one end of the upstream filter segment 150 and the downstream filter segment 170, respectively.

In addition, a portion of the outer circumferential surface of the hard capsule 180 may contact the porous wrapper or the non-porous wrapper surrounding the filter unit 120. Specifically, the hard capsule 180 may have an outer diameter of the same size as the outer diameter of the aerosol-generating rod 100, and thus the hard capsule 180 constituting the capsule filter segment 160 in the filter unit 120 may be filtered. It may come into contact with the wrapper surrounding the part 120.

3 is a view for explaining an example of a capsule filter segment.

Specifically, the hard capsule 180 may have an outer diameter of about 5 mm to 9 mm, and preferably may have an outer diameter of 6 mm to 8 mm. However, the outer diameter of the hard capsule 180 is not limited to the above-described range.

In addition, the hard capsule 180 may have a length of about 10 mm to 20 mm, and preferably 16 mm to 18 mm. However, the length of the hard capsule 180 is not limited to the above-described range.

As the outer diameter of the hard capsule 180 is the same as the outer diameter of the aerosol-generating rod 100 and has a length of about 10 mm to 20 mm, the hard capsule 180 itself can constitute a filter segment in the form of a unit module. There will be.

At least one hole 300 or a slit may be formed at both ends of the hard capsule 180 to allow air flow therethrough. Through the holes 300 or slits formed at both ends of the hard capsule 180, it is possible to secure an airflow path in the longitudinal direction of the aerosol-generating rod 100. Here, the longitudinal direction means the longitudinal axis direction of the aerosol-generating rod 100 of FIG. 1.

In addition, through the holes 300 or slits formed at both ends of the hard capsule 180, in order to minimize the resistance of the air flow passing in the longitudinal direction of the aerosol generating rod 100, the porosity in the hard capsule 180 is 30 % Or more, but is not limited thereto.

The adsorption component may include at least one of activated carbon, zeolite, sepiolite, alumina, and carbonaceous polymer.

The tobacco component may include at least one of tobacco beads, platy leaf sheets, cut filler and strands. Tobacco beads may include tobacco leaf flakes, tobacco stems and / or tobacco fines generated during tobacco processing. The leaflet sheet may contain other additives such as wood cellulose fiber. Also, cuts can be produced by finely cutting the tobacco sheet (or slurry leaflet sheet). The tobacco component may function as a coolant that lowers the temperature of the aerosol passing through holes or slits formed at both ends of the hard capsule 180. In addition, the tobacco component carried in the hard capsule 180 can enrich the flavor of the cigarette delivered to the user and increase the amount of nicotine migration.

In step 410, the downstream filter segment 170 may be prepared. Specifically, the downstream filter segment 170 may be made of cellulose acetate and may be in the form of a recess, but is not limited thereto.

In step 420, the upstream filter segment 150 may be positioned to be spaced a predetermined distance from the downstream filter segment 170 to form a cavity. The upstream filter segment 150 may be a cellulose acetate filter, and in the filter forming apparatus, the downstream filter segment 170 and the upstream filter segment 150 may be arranged in a spaced apart state.

In step 430, the hard capsule 180 may be positioned in the cavity.
