Description

Technical Field

[0001] This utility model belongs to the field of heated cigarette technology, specifically relating to an aerosol generating product that can limit the position of the flavor capsule. Background Technology

[0002] As consumers become increasingly health-conscious and demand more personalized experiences with cigarette products, the tobacco industry is constantly responding to these evolving needs by developing various smoking products with reduced tar and harm. Among these, heated cigarettes, due to their heating method differing from traditional cigarettes, offer a healthier smoking experience while satisfying consumers' sensory requirements. However, maintaining the aroma persistence and enhancing the flavor of heated cigarettes has always been a technical challenge for the tobacco industry. One solution is to add flavored capsules to the filter section of heated cigarettes. When inhaled, the user pops the capsule, allowing the flavoring substances within to mix with the smoke and be inhaled, thus enhancing the aroma.

[0003] Traditional cigarette filters typically use low-denier cellulose acetate tow. However, in modern heated cigarettes, to reduce smoke trapping, the filter typically uses high-denier (larger diameter) tow, resulting in a smaller tow quantity. Therefore, when a flavor capsule is included in the filter of a heated cigarette, the smaller tow quantity increases the likelihood of the capsule slipping.

[0004] Furthermore, due to limitations imposed by heating devices, the length of heated cigarettes is generally within a certain range. When a heated cigarette has many functional sections, resulting in a short filter section (e.g., 7-8mm), the flavor capsule may slide to the upstream or downstream section of the filter when the user pops it. This can make it difficult for the user to find the capsule and pop it for added flavor. Alternatively, if the capsule slides to the downstream section of the filter and is then popped, the flavoring from the capsule may be sprayed directly into the user's mouth, affecting the smoking experience.

[0005] This application is submitted in order to address the above issues. Utility Model Content

[0006] In this application, the direction of movement of the flue gas generated by the heating of the smoke-generating section 1 when the aerosol product is inhaled by the user is denoted as from upstream to downstream.

[0007] Aerosol-generating products have upstream and downstream components. Each segment of an aerosol-generating product, such as smoke-generating segment 1, hollow cooling segment 3, cellulose acetate bursting segment 4, and end-sealing segment 5, also has its own upstream and downstream components.

[0008] The axial direction of this application is the direction of the central axis of the aerosol-generated product.

[0009] In this application, the radial direction is the direction perpendicular to the axial direction, and it is also the cross-sectional direction of the aerosol-generated article.

[0010] The first aspect of this application provides an aerosol generating product capable of limiting the position of burst beads, the aerosol generating product comprising, from upstream to downstream: a smoke generating section 1, a hollow cooling section 3, a cellulose acetate burst bead section 4, and an end sealing section 5;

[0011] The hollow cooling section 3 is a tubular structure, and the diameter of the inner cavity 3-1 of the tubular structure is 0.5 to 2.3 mm.

[0012] The acetate fiber bursting bead segment 4 is a solid fiber bundle segment, and bursting beads 6 are disposed inside the solid fiber bundle segment;

[0013] The bursting bead 6 contains a fragrance, and the diameter of the bursting bead 6 is 2.8–3.2 mm;

[0014] The end sealing section 5 is a columnar structure, and the columnar structure has a plurality of axially extending airflow channels 5-1. The plurality of airflow channels 5-1 are distributed along the outer periphery of the columnar structure, and the diameter of the airflow channels 5-1 is 1-2 mm.

[0015] The projection of the inner cavity 3-1 of the hollow cooling section 3 along the axial direction does not overlap with the projection of the several airflow channels 5-1 along the axial direction. In other words, the inner cavity 3-1 and the several airflow channels 5-1 do not overlap in the radial direction.

[0016] Because the diameter of the inner cavity 3-1 of the hollow cooling section 3 is 0.5–2.3 mm, much smaller than the diameter of the bursting bead 6, even if the bursting bead 6 deforms to some extent when squeezed, it is not easy for it to slide into the hollow cooling section 3. Furthermore, the end-sealing section 5, with its columnar structure, lacks an airflow channel 5-1 in the center; therefore, the end-sealing section 5 also serves to seal the bursting bead 6. Even if the bursting bead 6 deforms to some extent when squeezed, it will not slide into the end-sealing section 5. This design ensures that the bursting bead 6 is confined within the cellulose acetate bursting bead section 4 by the hollow cooling section 3 and the end-sealing section 5.

[0017] The smoke-generating section 1 contains a smoke-generating substance.

[0018] Preferably, the number of airflow channels 5-1 is 3-5. The number of burst beads 6 is one.

[0019] Preferably, the hollow cooling section 3 is made of cellulose acetate or silicone.

[0020] Preferably, the end sealing section 5 is made of cellulose acetate or silicone.

[0021] Preferably, a support section 2 is provided between the smoke-generating section 1 and the hollow cooling section 3;

[0022] The support section 2 is a tubular structure, and the inner diameter of the support section 2 is larger than the inner diameter of the hollow cooling section 3.

[0023] The support section 2 can be a cellulose acetate hollow tube, a paper tube, or other tubular structure. For example, the wall of the support section 2 can be a grooved corrugated component, and the support section 2 can be a tubular structure formed by an outer tube, a grooved corrugated layer, and an inner tube. The groove shape of the grooved corrugated layer can be V-shaped.

[0024] The second aspect of this application provides a method for limiting the bursting beads 6 and cooling the flue gas, wherein the limiting of the bursting beads 6 and the cooling of the flue gas are for an aerosol-generated article containing bursting beads 6, and the method includes using the aerosol-generated article described in the first aspect.

[0025] Preferably, the method includes the following steps:

[0026] The smoke-generating material in the smoke-generating section 1 is heated, and the smoke generated in the smoke-generating section 1 is drawn into the user's lungs after passing through the hollow cooling section 3, the cellulose acetate bursting bead section 4, and the end sealing section 5.

[0027] When the flue gas moves from the cellulose acetate bursting bead section 4 to the end sealing section 5, the flue gas enters the airflow channel 5-1 distributed along the outer periphery of the columnar structure. In this process, the flue gas flow path is changed, the flue gas residence time is extended, the flue gas is dispersed, and the contact area between the flue gas and the columnar structure is increased, which further cools the flue gas.

[0028] According to Bernoulli's principle, as the flue gas travels from the cellulose acetate bursting bead section 4 to the end-sealing section 5, the diameter of the airflow channel 5-1 in the end-sealing section 5 is smaller than that in the cellulose acetate bursting bead section 4, resulting in a smaller cross-section of the airflow channel. This leads to an increase in flue gas velocity, a decrease in pressure, and a drop in airflow temperature.

[0029] Meanwhile, because the projection of the inner cavity 3-1 of the hollow cooling section 3 along the axial direction does not overlap with the projection of the several airflow channels 5-1 along the axial direction, and the several airflow channels 5-1 are distributed along the outer periphery of the columnar structure, in other words, there is no airflow channel 5-1 at the center of the columnar structure of the end-sealing section 5. Therefore, the center of the columnar structure of the end-sealing section 5 can play a role in sealing the bursting beads 6.

[0030] The cellulose acetate tow used in the cellulose acetate bursting segment of this application is generally made of high denier and thicker diameter tow, so that the number of fiber tows is relatively small, which can reduce the interception effect of the cellulose acetate bursting segment on flue gas.

[0031] When the tubular structure material of the hollow cooling section 3 and the end sealing section 5 in this application is made of cellulose acetate bundles, high-density cellulose acetate bundles, such as processed low-denier cellulose acetate bundles, will be used to prevent flue gas from flowing into the cellulose acetate bundles on the pipe wall and reduce the interception effect of the cellulose acetate bundles on the flue gas.

[0032] Of course, when silicone is used as the material for the hollow cooling section 3 and the end sealing section 5, the flue gas can be directly prevented from flowing into the pipe wall.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The acetate bead segment 4 is filled with burst beads 6. This application designs the structure of the two segments adjacent to the acetate bead segment 4 so that the burst beads 6 can be effectively sealed in the acetate bead segment 4, preventing the burst beads from sliding to the upstream or downstream segment of the acetate bead segment when the user squeezes them.

[0035] Furthermore, this application ensures that the axial projection of the inner cavity 3-1 of the hollow cooling section 3 does not overlap with the axial projection of the several airflow channels 5-1. Thus, when the flue gas moves from the cellulose acetate bead section 4 to the end sealing section 5, the flue gas enters the airflow channels 5-1 distributed along the outer periphery of the columnar structure. This process alters the flue gas flow path, prolongs the flue gas residence time, disperses the flue gas, and increases the contact area between the flue gas and the columnar structure, further cooling the flue gas.
