[0063] FIG. 1 illustrates an article 1 according to an embodiment of the present invention. The article 1 has an aerosol at its distal end. The tubular cooling cell includes a rod of steam generating material 2 and a mouth end segment 3 at the opposite or proximal end. a segment 4 located between the aerosol-generating material 2 and the mouth end segment 3 and having an inner surface 5 The aerosol-generating material 2, the tubular cooling segment 4, and the mouth end segment 3 are It is aligned longitudinally along the longitudinal axis XX.

[0064] The aerosol-generating material 2 may contain an aerosol-forming material such as glycerol. In some examples, the aerosol-forming material may be another material described herein or a combination thereof. The aerosol-forming material transports compounds, such as flavor compounds, from the aerosol-generating substrate 2 to the consumer. It has been shown that making it easier to move improves the perceived performance of item 1. However, the aerosol generator in the article 1 for use in a non-combustion aerosol delivery system By adding such an aerosol-forming material to the raw substrate 2, the aerosol-generating material 2 is heated. When aerosolized by the article 1, it increases the mass of the aerosol delivered by the article 1. This increased mass causes the aerosol to travel to the mouth end segment 3. The aerosol is maintained at a higher temperature as it passes through the mouth end segment 3. As it passes through, the aerosol transfers heat into the mouth end segment 3, which is then applied to the consumer's lips during use. The outer surface of the mouth end segment 3 is heated, including the area that comes into contact with the mouth end segment. The temperature and / or aerosol temperature may be adjusted to suit the consumer's needs, e.g., when smoking a conventional cigarette. Therefore, if the mouth end segment 3 is It is desirable to lower the temperature of the aerosol to prevent it from becoming too warm.

[0065] In the embodiment of the present invention, the tubular cooling segments 4 are cooled by air drawn into the tubular cooling segments 4. The cooling air is drawn into the tubular cooling segment 4 through the ventilation area 7. The air being drawn in mixes with the aerosol generated by the aerosol generating material 2, This acts to cool the aerosol as it travels towards the mouth end segment 3, The ventilation area 7 extends along the length of the tubular cooling segment 4. The aerosol-generating material 3 may be positioned closer to the mouth end segment 3 along the length than the aerosol-generating material 3 .

[0066] As shown in FIG. 1, the aerosol-generating material 2 is wrapped in a wrapper 8. The tip 4 and mouth end segment 3 are wrapped in a plug wrapper 9. Tipping paper 10 connects the aerosol generating material 2 to the tubular cooling segment 4 and the mouth end segment 3. Tipping paper 10 covers both the tubular cooling segment 4 and the mouth end segment 3. It extends over a part of the aerosol-generating material 2 .

[0067] As shown in FIG. 2, the embodiment of article 1 includes a tubular cooling segment 4 and a mouth end segment 3. The filter segment 11 may further include a filter segment 11 located between the filter segments 11 and 12. 11 may be formed from filamentary tow, optionally the filamentary tow being In this configuration, the aerosol-generating substrate 2 is wrapped in a wrapper 8. The filter segment 11 is wrapped in a first plug wrapper 12. The cooling segment 4, the wrapped filter segment 11 and the mouth end segment 3 are The aerosol-generating material 2 is then wrapped in a second plug wrapper 9. Tipping paper 10 encases the aerosol-generating material 2. The cooling segment 4, the filter segment 11 and the mouth end segment 3 are connected to The tipping paper 10 connects the tubular cooling segment 4, the filter segment 11 and the mouthpiece. The article 1 covers the end segment 3 and extends over a portion of the aerosol-generating material 2. Alternatively, a longer filter segment 11 may be included in place of the mouth end segment 3. In this embodiment, article 1 comprises an aerosol-generating substrate 2, a tubular cooling segment 4, and a and a filter segment 11. The filter segment 11 is connected to the mouth end segment 3. It is long to fill the space left vacant by the absence of

[0068] 3A and 3B are tubular cooling segments taken along line AA in FIGS. 1 and 2, respectively. In some embodiments, the tubular cooling segment 4 is made of a fibrous material such as paper. If the tubular cooling segment 4 is made of a fibrous material, the fibrous material may be The fiber material may be filamentary tow, optionally cellulose acetate. The wall thickness of the tubular cooling segment 4 if the segment 4 is formed from filamentary tow The tubular cooling segment 4 is made of paper, as shown in Figure 3A, or several 3B than if it were made from other materials.

[0069] If the tubular cooling segment 4 is made of a material that has a certain degree of air permeability, the ventilation area 7 may not extend through the tubular cooling segment 4, but may pass through the ventilation area 7. The air entering the tubular passage of the tubular cooling segment 4 passes through the tubular cooling segment 4. The tubular cooling segment 4 is arranged so that the aerosol diffuses through the tubular cooling segment 4 before mixing with the aerosol. It is also possible that the inner surface 5 of the slit 4 is not reached. Such an embodiment will be described below with reference to FIG. will be explained in detail.

[0070] The ventilation area 7 may include at least one ventilation hole 13 in the tubular cooling segment 4 . As shown in Figures 3A and 3B, the ventilation zones are evenly spaced around the circumference of the tubular cooling segment 4. The ventilation area 7 includes four ventilation holes 13 formed in the tubular cooling segment 4. may include any number of holes 13 spaced any distance from each other around the circumference of the The ventilation area 7 also extends within the tubular cooling segment 4 and extends in the circumferential direction of the tubular cooling segment 4. Each row may include one or more rows of holes 13 arranged in a line. Each row may have a tubular cooling The cooling segments 4 may be spaced apart in a direction along the longitudinal axis XX of the cooling segment 4.

[0071] The holes 13 extend perpendicularly to the longitudinal axis XX of the tubular cooling segment 4. However, the air may enter the tubular cooling segments 4 through holes 13. and towards the longitudinal axis but at an angle towards the distal end of the article 1 or towards the mouth end segment. The holes 13 are arranged at an angle to the longitudinal axis XX so that they enter the tube cooling tube 3 at an angle. It is also envisioned that the cooling section 4 may extend through the cooling section 4.

[0072] As shown in Figures 3A and 3B, each hole allows air entering the tubular cooling segment 4 to As shown by arrows S in 3B, the tube is cooled to generate a swirling flow inside the tubular cooling segment 4. This swirl flow may extend into the tubular cooling segment through holes 13. The air entering the tubular cooling segment 4 flows longitudinally along the axis XX of the tubular cooling segment 4. This promotes mixing with the aerosol moving in the direction of the particle.

[0073] To generate the swirl flow, the holes 13 are preferably positioned so that the air flows through the inner surface 5 of the tubular cooling segment 4. The cooling pipe 4 is positioned so as to enter the tubular cooling segment 4 tangentially or nearly tangentially to the cooling pipe 4 . The air entering the tubular cooling segment 4 through the holes 13 therefore passes through the tubular path close to the inner surface 5. The swept passage around the tubular cooling segment 4 generates vortices and causes mixing. The good mixing condition in the tubular cooling segment 4 caused by the generated vortex promotes Before the aerosol generated by the aerosol generating material 2 reaches the mouth end segment 3, This increases the cooling of the aerosol. Therefore, the temperature of the mouth end segment 3 decreases. do.

[0074] Naturally, the air must enter the tubular cooling segment 4 tangent to its inner surface 5. is parallel to both the tangent and the line intersecting the longitudinal axis XX of the tubular cooling segment 4. and may enter along paths offset from these tangent and intersecting lines. 1 is parallel to the hole 13 and is offset from the line YY extending through the axis XX as shown in FIG. The set distance is close to the maximum, where it is almost tangent to the inner surface 5 of the tubular cooling segment 4. The dashed line 14 in FIG. 3A indicates another possible location of the hole 13 between the tangent position and the line YY. The position of the hole is shown. Naturally, the swirling effect that occurs becomes Become smaller.

[0075] 4A and 4B illustrate another embodiment of the article 1. In FIG. The air entering the cooling segment 4 causes the aerosol to flow from the aerosol generating material 2 to the inlet end segment. When flowing toward port 3, the aerosol flows in the opposite direction to the aerosol flow. This is achieved by ventilation holes 7 which extend in an angled direction towards the aerosol-generating material. In FIG. 4B, the ventilation holes are formed so that the air entering the tubular cooling segment 4 can pass through the ventilation holes. The flow direction of the aerosol is the same as that of the aerosol flowing from the aerosol generating material 2 to the mouth end segment 3. This is angled towards the mouth end segment 3. This is achieved by ventilation holes 7 extending in the direction.

[0076] In some embodiments, the ventilation holes 7 taper in the direction they extend into the tubular cooling segment 4. In other words, the diameter of each hole 13 on the outer surface of the tubular cooling segment 4 may be The diameter of the hole 13 at the inner surface 5 of the ment 4 can be larger than that of the hole 13 at the inner surface 5 of the ment 4.

[0077] In embodiments including multiple rows of holes 13, the multiple rows of holes 13 are located within the tubular cooling segment 4. For example, the first row of holes 13 may be configured to create opposing swirling effects. The cooling tubular segments 4 may be configured to generate a clockwise vortex, and the second row The holes 13 may be configured to generate a counterclockwise vortex within the tubular cooling segment 4. .

[0078] The ventilation holes 13 may be of any shape or size, and may even be cylindrical. In another embodiment, the holes 13 are slots 13. The slots 13 are similar to the article shown in FIG. longitudinally along the axis XX of the tubular cooling segment 4 as shown in the side view of a portion of the proximal end of Alternatively, slot 13 may have a major dimension extending in the vicinity of the article as shown in FIG. A direction perpendicular to the longitudinal axis XX of the tubular cooling segment 4 as shown in a side view of a portion of the end Further, the major dimension of the slot 13 may be the major dimension of the slot 13. The major dimension of the slot 13 extends longitudinally along the axis XX. The slots may extend in a direction angled between the maximum extending in a direction perpendicular to X. The nozzles 13 may be spaced apart circumferentially around the tubular cooling segment 4. Furthermore, one or more rows of slots arranged circumferentially around the tubular cooling segment 4 may be provided. 13, in which case each row is longitudinally aligned along the axis XX of the tubular cooling segment 4. The ventilation area 7 is provided by a slot 13. If so, these slots are offset in the same way that holes 13 are offset in Figures 3A and 3B. Alternatively, the slots may be offset relative to the longitudinal axis of the tubular cooling segment 4. It may extend radially towards XX.

[0079] In embodiments including multiple rows of slots 13, the multiple rows of slots 13 are tubular cooling segments. For example, the first row of The slots 13 may be configured to generate a clockwise vortex within the tubular cooling segment 4. The second row of slots 13 preferably generates a counterclockwise vortex within the tubular cooling segment 4. It may be configured so that

[0080] FIG. 6 illustrates a tubular cooling segment according to an embodiment of the present invention. The slot 13 of the tubular cooling segment 4 includes a flap 17. axially extending at an angle to deflect the aerosol flowing through the tubular cooling segment 4. For example, the flap 17 is angled within the tubular cooling segment 4 to provide a suction 1. The slot 13 may extend in a direction toward the opening end segment 3. The air drawn into the tubular cooling segment 4 is generated by the aerosol generating material 2. The aerosol flows in the tubular cooling segment 4 toward the mouth end segment 3. Apart from this, the flap 17 is also provided to prevent aerosol generation in the tubular cooling segment 4. The slots 13 may extend at an angle in the direction toward the green material 2. The air drawn into the cooling segment 4 is the air emitted by the aerosol-generating material 2. The direction opposite to the direction in which the aerosol flows through the tubular cooling segment 4 toward the mouth end segment 3. Of course, the flap 17 can be positioned within the tubular cooling segment 4 at any angle. The presence of the flap 17 in the tubular cooling segment 4 allows the aerosol-generating material 2 to The mixture of the aerosol and ventilation air emitted by the aerosol is passed through the tubular cooling segment 4. The flow of air is diverted by the flap 17, which promotes the flow of air. The slots 13 are cut into the tubular cooling segments 4 so that some of the cut material remains in the tubular cooling segments. The flap 17 may be formed by remaining attached to the tubular segment 4. It may be angled by mechanical means into the cooling segment 4. The flap 17 cools the tubular cooling segments via non-mechanical means such as a controlled air blast. The hole 4 may be bent at an angle.

[0081] In any embodiment of the present invention, the tubular cooling segment 4 is made of a material that has some degree of air permeability. For example, the tubular cooling segment 4 may be made of a fibrous material such as paper. The fibrous material used to form the tubular cooling segment 4 is preferably a filamentary tubular material. Alternatively, it may be cellulose acetate.

[0082] Holes or slots 13 forming the ventilation zone 7 penetrate the wall of the tubular cooling segment 4. However, the tubular cooling segments 4 may extend into the tubular passages. If the cooling tubular segment 4 is made of a material having a thickness of 1000 Å, the holes 13 may extend only through a portion of the wall of the cooling tubular segment 4. It is expected that this may be extended.

[0083] Referring to the cross-sectional view through the ventilation area 7 of the tubular cooling segment 4 in FIG. The ment 4 includes a wall 15 separated by inner and outer surfaces 5, 16. The duct 13 extends within the tubular cooling segment 4 from the outer surface 16 toward the inner surface 5. The air passing through the holes or slots 13 does not reach the ventilated material of the tubular cooling segment 4. The aerosol passes through a path extending through the tubular cooling segment 4, and the aerosol passing through the path The ventilation holes or slots 13 are formed on the inner surface 5 of the tubular cooling segment 4. The distance D2 may be 0.2 to 1 mm.

[0084] The holes or slots 13 do not reach the inner surface 5 of the tubular cooling segment 4. The air drawn into the tubular cooling segment 4 through the slot 13 is drawn over a distance D2. The cooling fluid penetrates the material of the tubular cooling segment 4 and spreads around the periphery of the inner surface 5 of the tubular cooling segment 4. Therefore, the inner surface 5 of the tubular cooling segment 4 is cooled more uniformly. The aerosol generated by the aerosol generating material 2 is cooled along the tubular cooling segment 4. 3. The air flows through the nozzle end segment 3 and acts as a cooling blanket, cooling the air as it passes through the nozzle end segment 3.

[0085] The cross-sectional view of FIG. 7 shows that holes or slots 13 direct air along the longitudinal axis X of the tubular cooling segment 4. Although the illustrated configuration is aligned to guide the radial direction toward -X, Of course, the holes or slots may extend through a portion of the wall of the tubular cooling segment 4. Additionally, they may be offset as described above with reference to Figures 3A and 3B.

[0086] FIG. 8 illustrates an aerosol-generating medium / material such as the aerosol-generating material 2 of the article 1 described herein. An example of a non-combustion aerosol delivery device 100 for generating an aerosol from a material is shown. In general, device 100 heats the aerosol-generating material of article 1 to may be used to generate an aerosol that is inhaled by a user of the chair 100. Device 100 and article 1 together form a non-combustion based aerosol delivery system.
