Description

Technical Field

[0001] This invention relates to the field of tobacco product technology, and more specifically to an aerosol-generating product. Background Technology

[0002] HNB (Heat Not Burn), also known as low-temperature cigarettes, is a new type of tobacco product that combines a heating device and a tobacco cartridge. Designed with the concept of "heating without burning," it uses a special heating device (the device) to heat processed tobacco (a special tobacco cartridge) to a certain temperature, enough to release smoke for inhalation. Its advantages include reduced harm and restoration of the pure taste and throat hit of traditional cigarettes, providing smokers with a smoking alternative that is closest to traditional cigarettes.

[0003] HNB consists of two parts: a heated tobacco device and an HNB cartridge. An HNB cartridge typically consists of three parts: a smoke-generating section, a cooling section, and a filter section. The smoke-generating section is an important component. After being heated in the heating chamber, the smoke-generating section emits smoke similar to that of traditional cigarettes. The smoke is then passed through the cooling section and the filter section before being inhaled by the user.

[0004] Currently available HNB (Heated Tobacco Bundle) cartridges primarily use reconstituted tobacco leaves or shredded tobacco as the core material, glycerin or propylene glycol as the smoke-generating agent, and add flavorings and other ingredients. They generate smoke at a relatively low heating temperature (typically 300-350℃) to achieve the smoking effect. Although HNB products release fewer harmful substances, the actual heating temperature is significantly lower than traditional tobacco, resulting in less smoke and a less pleasant smoking experience. Increasing the amount of smoke produced requires increasing the amounts of glycerin and propylene glycol. However, glycerin itself has excellent hygroscopic properties, leading to high hygroscopicity in the product, causing significant inconvenience in later processing and storage. Furthermore, its high hygroscopicity after opening the packaging can cause uneven smoking of different cigarettes. Additionally, heat transfer requires a certain amount of time, resulting in inconsistent smoke production even within the same cigarette.

[0005] To increase smoke production, existing technologies have mentioned using propylene glycol / glycerol-coated capsules as aerosol-generating matrix, but most related technologies simply use capsules as a supplement to tobacco materials. Some patents also mention using pure capsules directly as aerosol-generating material and placing them in the aerosol-generating matrix section; however, these technologies all use a single capsule and need to address the problem of core material leakage after capsule rupture, for example, by using an absorbent pad to absorb the capsule core material. Therefore, the relevant technical literature has not explicitly proposed using multiple capsules directly as aerosol-generating material, nor has it solved a series of technical problems associated with directly using capsules as aerosol-generating material. Summary of the Invention

[0006] Therefore, this invention provides an HNB product, namely an aerosol generating product, which can further reduce the heating release temperature, thereby reducing the harm of smoke, and can make the smoke more persistent, improving the user's smoking experience.

[0007] Therefore, the embodiments of the present invention provide the following technical solutions:

[0008] An aerosol generating article includes an aerosol generating matrix segment, wherein the aerosol generating matrix segment includes a plurality of aerosol generating capsules. With the same smoke release design, a multi-capsule system can reduce the amount of smoke-generating agent (such as propylene glycol / glycerol) in each capsule. During the heating and release process, the capsules closer to the heat source rupture first. Since each capsule has less core material, the core material can adhere to the capsule shell. The smoke-generating agent in the core material continues to evaporate and form smoke, carrying away some heat. As the smoke-generating agent evaporates and is consumed, heat continues to accumulate, and capsules slightly away from the heat source will also rupture. The corresponding smoke-generating agent in the core material is released and continues to evaporate and carry away some heat until the corresponding smoke-generating agent is almost exhausted. Heat continues to accumulate, and capsules far from the heat source will then rupture. Therefore, multiple capsules will rupture sequentially when continuously heated, and the core material will not flow out in large quantities at once. This avoids the technical problem of a large amount of core material flowing out instantly after a single capsule ruptures, and there is no need for a specific absorption pad to absorb the core material. Furthermore, the sequential rupture of multiple capsules and the gradual release of the smoke-generating agent result in better smoke continuity and stability, and more uniform release.

[0009] Optionally or preferably, the aerosol generating matrix segment does not contain other aerosol generating materials. Since different aerosol generating materials have inconsistent heating release temperatures, aerosol generating capsules can release at lower temperatures, thus further reducing the heating release temperature. Using a single type of aerosol generating material, such as aerosol generating capsules, allows for maintaining release efficiency while using a lower heating release temperature, thereby saving energy and reducing potentially harmful components released at high temperatures.

[0010] Optionally or preferably, the aerosol generating capsules fill the aerosol generating matrix segment in a randomly dense or randomly sparse manner. Random filling ensures that the aerosol generating material has a high porosity, thereby reducing absorption resistance; even after heating and rupture, the absorption resistance will not increase significantly.

[0011] Optionally or preferably, the porosity of the aerosol generating capsule filling the aerosol generating matrix segment is greater than 25%, and more preferably greater than 36%. A lower porosity will result in greater suction resistance. After heating, the capsule may rupture and collapse, leading to increased suction resistance. Therefore, an appropriate porosity helps maintain a good vaping experience.

[0012] Optionally or preferably, the aerosol generating capsules are filled into the aerosol generating matrix section, but not completely filled. To further increase the porosity, filling the aerosol generating matrix section with the capsules in a partially filled manner can further reduce suction resistance; simultaneously, during aspiration, the capsules move upwards with the aspiration, making them more loose, which also helps reduce suction resistance; additionally, the loose filling or partially filled state can also reduce the resistance to insertion of the central heating device into the aerosol generating matrix section.

[0013] Optionally or preferably, the vertical standing height of the aerosol-generating capsule within the aerosol-generating matrix section is less than the length of the aerosol-generating matrix section. Since the capsule does not completely fill the aerosol-generating matrix section, its standing height will be lower than the length of the aerosol-generating matrix section, thereby reducing suction resistance.

[0014] Optionally or preferably, the vertical static height of the aerosol generating capsule within the aerosol generating matrix section is less than 95% of the length of the aerosol generating matrix section. Preferably, the vertical static height of the aerosol generating capsule within the aerosol generating matrix section is less than 80% of the length of the aerosol generating matrix section. More preferably, the vertical static height of the aerosol generating capsule within the aerosol generating matrix section is less than 60% of the length of the aerosol generating matrix section. In practice, further reducing the volume of the capsule within the aerosol generating matrix section, where necessary, helps to further reduce draw resistance. However, lower filling volume and filling density will also reduce the vapor release effect and affect the vaping experience.

[0015] Optionally or preferably, the length of the aerosol-generating matrix segment is 10% to 60% of the total length of the aerosol-generating article. Since the capsule particle size is adjustable, the length of the aerosol-generating matrix segment filled with the capsule is adjustable and the adjustment range can be sufficiently wide to adapt to different heating methods or release effects.

[0016] Optionally or preferably, multiple aerosol-generating capsules may have the same or different particle sizes. Combining multiple particle sizes can also optimize the matching with heating methods or release effects.

[0017] Optionally or preferably, the particle size of the aerosol generating capsules is 0.2–8 mm, preferably 1–3 mm, and more preferably 1.5–2.5 mm. When the smoke release is designed to be the same, if the capsule particle size is too small, the amount of core material in each capsule is lower. Although the uniformity of release will improve, it will also lead to a decrease in the carrying capacity of the smoke-generating agent and a reduction in the filling porosity, all of which adversely affect the smoke release effect. Therefore, a suitable particle size, especially a moderate particle size, can ensure a good inhalation experience and also prevent the problem of large-diameter capsule core material flowing out of the aerosol generating product.

[0018] Optionally or preferably, the core material in the aerosol-generated capsule is in the form of a paste, a colloid, or a solid-liquid mixture. Liquid core materials have better flowability and are less likely to adhere to the capsule shell. If the core material is not a pure liquid or has a certain viscosity, it is easier to adhere to the capsule shell even after heating, which can effectively prevent the core material from flowing out of the aerosol-generated product.

[0019] Optionally or preferably, the smoke-generating agent in the aerosol-generating capsule accounts for 4% to 60% of the mass of the core material, preferably 40% to 60%. A higher content of smoke-generating agent can increase the carrying capacity of the capsule's smoke-generating components, thereby ensuring a good smoke effect.

[0020] Optionally or preferably, the smoke-generating agent in the aerosol-generating capsule includes propylene glycol and / or glycerin. Preferably, the smoke-generating agent includes both propylene glycol and glycerin. Propylene glycol and glycerin are common smoke-generating agents, and their combination achieves a balance between rapid release and smoke effect, enabling sufficient smoke production at low temperatures.

[0021] Optionally or preferably, the core material of the aerosol-generating capsule may also include one or more of the following: flavorings, extracts, nicotine, and nicotine salts. By adding these components, aerosol-generating products can be given different flavors to meet users' different needs in terms of aroma, health, and taste.

[0022] Optionally or preferably, the smoke-generating agents within multiple aerosol-generating capsules may have the same or different compositions and proportions. By using capsules with different compositions and proportions, different levels of release effects can be achieved. For example, by setting different types of capsules with different spatial segments, the early and late release stages can produce drastically different smoke-generating effects.

[0023] Optionally or preferably, the shell material of the aerosol-generating capsule includes any one or more of the following: plant gum, animal gum, microbial gum, starch, and starch-modified materials. These materials offer good safety, are less prone to breakage compared to synthetic chemical polymers, and result in capsules with good strength.

[0024] Optionally or preferably, the shell thickness of the aerosol-generating capsule is 50–150 μm. A higher shell thickness increases the difficulty of the capsule rupturing under heat, reducing the release rate; a lower shell thickness results in insufficient capsule strength and makes it difficult to manufacture and process.

[0025] Optionally or preferably, the aerosol generating matrix segment further includes one or more excipient capsules, said excipient capsules comprising any one or more of the following: flavor capsules, extract capsules, nicotine capsules, and nicotine salt capsules. By adding excipient capsules, the variety and flavor of aerosol-generated products can be enriched, and the mixing of multiple types of capsules makes it easier to adjust the taste of aerosol-generated products. Furthermore, the preparation of single-component capsules is easier than that of capsules with complex components, thus reducing production difficulty.

[0026] Optionally or preferably, the volume ratio of the excipient capsules to the aerosol generating capsules within the aerosol generating matrix segment is 10:1 to 1:10. By adjusting the ratio of the excipient capsules to the aerosol generating capsules, the flavor and mouthfeel of the aerosol-generated product can be effectively adjusted.

[0027] Optionally or preferably, the aerosol-generating article has a sealing element at one end near the aerosol-generating matrix section. When the aerosol-generating capsule is not pre-packaged as a single unit and the aerosol-generating article is manufactured by directly filling the tube with the capsule, a sealing element is necessary.

[0028] Optionally or preferably, the sealing element is paper, non-woven fabric, woven fabric, or thermally conductive material. Using the above-mentioned sealing element can achieve effective sealing and meet various performance parameters required for aerosol release.

[0029] Optionally or preferably, the thermally conductive material is metal foil, preferably aluminum foil. Sealing with the thermally conductive material can effectively absorb heat and rapidly transfer it to the aerosol-generating capsules, thus increasing the aerosol release rate.

[0030] Optionally or preferably, the sealing material is a cellulose acetate rod or a cotton swab. Using a cellulose rod for sealing may be more effective with certain heating methods, such as center heating, as the cellulose rod can help clean the center heating element or heating needle.

[0031] Optionally or preferably, the aerosol generating product also includes a filter section. The filter section can help filter out off-flavors from the aerosol and improve the uniformity of the smoke.

[0032] Optionally or preferably, the filter section includes one or more filter elements. The use of multiple filter elements can produce different filtration effects individually, while achieving the overall filtration purpose.

[0033] Optionally or preferably, multiple filter components are connected sequentially along the axial or radial direction of the filter section. Connecting the filter components axially can achieve multiple filtration purposes, while connecting them radially can improve smoke uniformity.

[0034] Optionally or preferably, the filter element is a solid porous structure or a hollow structure filter rod. A solid structure ensures filtration effectiveness, while a hollow structure reduces draw resistance and minimizes smoke absorption.

[0035] Optionally or preferably, the filter section includes a solid porous filter rod and a hollow filter rod, which are connected along the axial direction of the filter section. The combination of these two types of filter rods achieves effective filtration while reducing suction resistance and minimizing flue gas loss.

[0036] Optionally or preferably, the aerosol matrix section and the filter section are enclosed in the same tube. This shared tube design reduces manufacturing complexity and increases production efficiency.

[0037] Optionally or preferably, the filter section and the aerosol generating matrix section are adjacent in the axial direction of the aerosol generating product tube, and the filter section limits the length of the aerosol generating section. By limiting the space of the aerosol generating matrix section by the filter section, the structural complexity of the aerosol generating product can be reduced; in the low-temperature release system of this invention, conventional filter sections can achieve filtration and limiting effects without the problem of filter rod thermal melting.

[0038] Optionally or preferably, the aerosol-generating article further includes a limiting member that restricts the aerosol-generating capsule within a fixed or movable area. Using the limiting member to fix the aerosol-generating capsule in a specific or movable area contributes to the stability of the overall structure.

[0039] Optionally or preferably, the limiting element is movable, which restricts the movement area of ​​the aerosol-generating capsule. Movable limiting elements allow for a more flexible aerosol-generating matrix space and also facilitate production.

[0040] Optionally or preferably, the limiting element has a cooling effect. When necessary, the limiting element can simultaneously achieve a cooling effect to reduce the structural complexity of the aerosol-generated product.

[0041] Optionally or preferably, the limiting element has a supporting function. When necessary, the limiting element supporting the tube can also reduce the structural complexity of the aerosol-generated product.

[0042] Optionally or preferably, the limiting element is a preformed part or a sheet roll with airflow channels. Preformed parts have higher strength and are suitable for providing higher strength support; while sheet rolls are more suitable for achieving a cooling effect.

[0043] Optionally or preferably, the aerosol-generating capsule is packaged as a single unit, fixed inside the tube, and serves as the aerosol-generating matrix segment. Prefabricating the capsule as a single unit helps improve the ease and consistency of assembly.

[0044] Optionally or preferably, the aerosol-generating capsules are packaged as a single unit using a thermally conductive material. Pre-packaging the capsules as a single unit using a thermally conductive material can improve the efficiency of heat transfer and enhance the release effect.

[0045] Optionally or preferably, one or more pores are provided on the tube corresponding to the aerosol generation matrix section. Perforating the tube can increase the airflow and effectively reduce the suction resistance; at the same time, during the thermal release of the multi-capsule system, the bottom capsules rupture and accumulate, and the core liquid adheres, which may increase the suction resistance. Therefore, perforating the side can supplement the airflow and reduce the suction resistance in the later stage of thermal release.

[0046] Optionally or preferably, multiple pores are distributed on the tube body corresponding to a portion or all of the aerosol generation matrix section. This pore distribution design can further optimize the suction resistance issue.

[0047] Optionally or preferably, a thermally conductive layer is provided on the inner surface of the tube of the aerosol generating article, corresponding to the section of the aerosol generating matrix. The thermally conductive layer facilitates heat absorption and rapid transfer, effectively increasing the aerosol release rate.

[0048] Optionally or preferably, the thermally conductive layer is made of metal foil, with aluminum foil being the preferred material. Metals generally have excellent thermal conductivity, and aluminum foil is a mature metal foil material. Choosing metal foil, especially aluminum foil, can ensure good thermal conductivity.

[0049] Optionally or preferably, the length of the thermally conductive layer is greater than or equal to the length of the aerosol generating matrix segment. By covering the entire aerosol generating matrix segment with the thermally conductive layer, comprehensive coverage of the thermal conductivity can be ensured.

[0050] Optionally or preferably, the length of the thermally conductive layer is shorter than the length of the aerosol generating matrix section. When the aerosol generating capsule filling amount is low, the length of the thermally conductive layer can be shorter. At the same time, in systems with higher release temperatures, this prevents the thermally conductive layer from transferring heat to the near-mouth section, thus affecting the temperature of the inlet flue gas.

[0051] Optionally or preferably, the length of the aerosol generating product tube is 30–84 mm and the diameter is 3.0–10.0 mm. The multi-capsule structure of the aerosol generating product can accommodate diverse tube structure parameters, thus meeting various application requirements.

[0052] Optionally or preferably, the filling amount of the aerosol generating capsule is 0.05–0.5 g, preferably 0.1–0.3 g. For a given amount of smoke release, a higher filling amount may lead to material waste, while a lower filling amount will reduce the persistence of aerosol generation. Therefore, a moderate filling amount can ensure a good inhalation experience.

[0053] Optionally or preferably, the filling amount of the aerosol generating capsules is 5 to 100 capsules, preferably 15 to 30 capsules. When the smoke release is designed to be the same, a lower number of capsules may result in too much core material in each capsule, which may cause the core material to flow out of the aerosol generating product; while a higher number of capsules will lead to an increase in draw resistance, affecting the vaping experience; at the same time, an appropriate filling amount can also ensure the uniformity of smoke release.

[0054] Furthermore, the aerosol-generating product provided in this embodiment of the invention includes multiple aerosol-generating capsules in the aerosol-generating matrix section. Compared to existing products using reconstituted tobacco leaves or shredded tobacco as core materials, this allows for uniform and sufficient smoke release at lower heating temperatures. This effectively reduces energy consumption and the release of harmful substances while improving the vaping experience. Moreover, the encapsulation of the capsules provides excellent protection for the core material, preventing quality changes due to external environmental influences and ensuring the stability of the core material during long-term product storage, thus better guaranteeing product quality. Compared to structures using a single aerosol-generating capsule, the multi-capsule system provides better continuity and uniformity of smoke during heating. Attached Figure Description

[0065] The principles and spirit of the invention will now be described with reference to exemplary embodiments shown in the accompanying drawings. It should be understood that these embodiments are described merely to enable those skilled in the art to better understand and implement the invention, and are not intended to limit the scope of the invention in any way. Furthermore, the described embodiments are only a portion of, and not all, of the embodiments of the invention.

[0066] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0067] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0068] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0069] In the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0071] To address the issues of low smoke output and high susceptibility to environmental factors in existing HNB (High-End Tobacco) cartridge products that primarily use reconstituted tobacco leaves or shredded tobacco as core materials, this invention provides an aerosol-generating product. This aerosol-generating product includes an aerosol-generating matrix section comprising multiple aerosol-generating capsules. This not only enables uniform and sufficient smoke release at lower heating temperatures, improving the smoker's experience, but also ensures product quality stability during long-term storage.

[0072] In some embodiments, the aerosol generating matrix segment may contain only the aforementioned aerosol generating capsules and not other aerosol generating materials.

[0073] In other embodiments, the aerosol generating matrix segment may also include the aforementioned aerosol generating capsules and other aerosol generating materials.

[0074] Furthermore, the aerosol generating capsules can be tightly packed or loosely packed within the aerosol generating matrix segment. Tight packing, for example, means that the vertical, naturally filled static height of the aerosol generating capsules within the aerosol generating matrix segment is equal to the length of the aerosol generating matrix segment; loose packing, also known as loose filling, means that the vertical, naturally filled static height of the aerosol generating capsules within the aerosol generating matrix segment is less than the length of the aerosol generating matrix segment.

[0075] The aerosol generating capsules can be filled into the aerosol generating matrix segment in a random dense or random sparse filling manner. Regardless of the filling method, the entire aerosol generating matrix segment can be filled, or the aerosol generating matrix segment can be left unfilled.

[0076] It should be noted that the aerosol generating capsules filled into the aerosol generating matrix segment will have a certain porosity. The porosity is the ratio of the volume outside the aerosol generating capsules in the aerosol generating matrix segment to the total volume in the aerosol generating matrix segment. For example, in some embodiments, the porosity is greater than 25%, and more preferably greater than 36%.

[0077] In some embodiments, the aerosol generating article has a sealing element at one end near the aerosol generating matrix section, and a limiting element and / or a filter section at the other end. The aerosol generating matrix section, the limiting element, and / or the filter section can be enclosed in the same tube. The length of the tube can be designed to be 30–84 mm, specifically 40 mm, 45 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc. The diameter of the tube can be 3.0–10.0 mm, specifically 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, etc.

[0078] In some embodiments, the aerosol generating capsule can be packaged as a single unit, fixed inside the tube, and serve as an aerosol generating matrix segment. In this manner, multiple aerosol generating capsules can be pre-packaged and inserted into the tube to form the aerosol generating matrix segment during manufacturing.

[0079] In some embodiments, the aerosol generating capsule is packaged as a single unit using a thermally conductive material. This material enables rapid heat transfer, increases the amount of smoke generated by the aerosol generating capsule, and shortens the waiting time until smoke is produced.

[0080] In this embodiment of the invention, the length of the aerosol generation matrix segment can be set arbitrarily, for example, it can be 10% to 60% of the total length of the aerosol generation product.

[0081] The specific structure of the aerosol-generated product of the present invention will be illustrated below with reference to the accompanying drawings.

[0082] like Figure 1 The diagram shown is a structural schematic of an aerosol-generated product provided in an embodiment of the present invention.

[0083] In this example, the aerosol generating article 10 includes an aerosol generating matrix section 101, which includes a plurality of aerosol generating capsules 104. The aerosol generating article 10 also includes a sealing element 105, a limiting element 102, and a filter section 103.

[0084] The sealing element 105 can be made of paper, non-woven fabric, woven fabric, or thermally conductive material, and can be directly adhered to one end face of the aerosol generating matrix section 101. The thermally conductive material can be, for example, metal foil, such as aluminum foil, to increase thermal conductivity and reduce heating waiting time during suction. Except in specific embodiments, the sealing element is generally breathable or has vents to ensure that airflow can enter the aerosol generating product.

[0085] The limiting member 102 is adjacent to the end of the aerosol generating matrix section 101 that is away from the end of the aerosol generating product 10, and the filter section 103 may be adjacent to or separated from the limiting member 102 by a certain distance.

[0086] In some embodiments, the limiting member 102 or the filter section 103 may not be provided. For example, the filter section 103 may be directly adjacent to the end of the aerosol generating matrix section 101 that is away from the end of the aerosol generating article 10. In this structural design, the filter section 103 can both filter the smoke and limit the aerosol generating capsule 104 to prevent it from leaking out.

[0087] The limiting member 102 is used to restrict the aerosol generating capsule 104 to a fixed area or a movable area. In some embodiments, the limiting member 102 may be movable, restricting the aerosol generating capsule 104 to an movable area, which is relative to the fixed area. The movable area refers to the area where the aerosol generating capsule is located, which is itself movable. For example, it may move left and right or rotate axially between the aerosol generating matrix section 101 and the filter section 103. In other embodiments, the limiting member 102 may also be fixed to restrict the aerosol generating capsule 104 to a fixed area.

[0088] The limiting component 102 not only limits the aerosol generating capsule 104 but also cools it down. The smoke generated by heating the aerosol generating product 10 first passes through the limiting component 102 before passing through the filter rod to the inhaler's mouth. Therefore, the limiting component 102 also cools the mouth, preventing burns from the smoke. Furthermore, the limiting component also provides support, strengthening the aerosol generating product and preventing deformation or dents in the tube.

[0089] In practical implementation, the limiting component 102 can be a preformed part or a rolled sheet part, and its specific structure is not limited, such as... Figure 4 The diagram illustrates some specific structural examples of the limiting member. To ensure unobstructed airflow, the limiting member 102 may also be provided with one or more airflow channels. The limiting member may be made of, but is not limited to, any of the following: plant fiber, resin, metal, etc. The airflow channels can reduce suction resistance and prevent the aerosol-generating capsule 104 from passing through.

[0090] In some embodiments, the filter section 103 may include one or more filter components. The plurality of filter components may be sequentially connected along the axial or radial direction of the filter section. The filter components may be, for example, solid, hollow, or porous filter rods, etc., and this embodiment of the invention does not limit the specific type. The filter rod may be formed from one or more fibers.

[0091] In some embodiments, the filter section 103 may include a solid porous filter rod and a hollow filter rod, the two types of filter rods being connected axially.

[0092] like Figure 2 As shown, it is another schematic structural view of the aerosol generating article provided by an embodiment of the present invention. In this figure, the aerosol generating capsule is not filled to the full in the aerosol generating matrix section.

[0093] The aerosol generating article of this example is different from Figure 1 the example shown in that Figure 2 the filter section 103 in Figure 1 is not shown in the aerosol generating article. Of course, the aerosol generating article provided by this embodiment can omit the filter section because the present invention uses capsules as aerosol generating materials, the components of the capsules are relatively clear, and they are released by low-temperature heating, so there is less miscellaneous gas; at the same time, the capsules are released at a low temperature, and there will be no obvious problem of hot smoke in the mouth even without a filter section.

[0094] As mentioned above, the aerosol generating capsules can be tightly filled or not tightly filled in the aerosol generating matrix section. As Figure 3 shown, in the case of non-tight filling in Figure 2 the embodiment, the vertical static height h of the aerosol generating capsule 104 in the aerosol generating matrix section 101 is less than the length H of the aerosol generating matrix section 101, that is, h < H, and the aerosol generating capsule 104 can move within the length H of the aerosol generating matrix section 101.

[0095] In some specific embodiments, the vertical static height of the aerosol generating capsule 104 in the aerosol generating matrix section 101 can be less than 95%, 85%, 80%, 75%, 60%, etc. of the length of the aerosol generating matrix section 101. The embodiments of the present invention do not limit this.

[0096] In specific implementation, the shape of the aerosol generating capsule 104 can be circular, oval, etc., and the particle size can be the same or different. The embodiments of the present invention do not limit this. For example, in some non-limiting embodiments, the particle size of the aerosol generating capsule 104 can be designed to be 0.2 - 8 mm, preferably 1 - 3 mm, and more preferably 1.5 - 2.5 mm. For example, it can be 1.8 mm, 2.0 mm, etc.

[0097] According to the different particle sizes of the aerosol generating capsules 104 and the different lengths of the aerosol generating matrix section 101, the number or weight of the aerosol generating capsules 104 filled in the aerosol generating matrix section 101 will also be different. For example, in some embodiments, the filling amount of the aerosol generating capsules 104 is 5 - 100 grains, preferably 15 - 30 grains, and in some specific embodiments, it can be preferably more than 20 grains. Again, for example, in some embodiments, the filling amount of the aerosol generating capsules 104 is 0.05 - 0.5 g, preferably 0.1 - 0.3 g.

[0098] In this embodiment of the invention, the core material of the aerosol generating capsule 104 mainly includes a smoke generating agent, and the mass ratio of the smoke generating agent to the core material can be, for example, 4% to 60%, preferably 40% to 60%.

[0099] In this embodiment of the invention, the main components of the smoke-generating agent include propylene glycol and / or glycerin. For example, in one embodiment, the smoke-generating agent comprises propylene glycol and glycerin, which account for 5-60 wt% of the core material weight. In some specific embodiments, propylene glycol and glycerin may account for 15-50 wt% of the core material weight. In other specific embodiments, propylene glycol and glycerin may account for 25-45 wt% of the core material weight, for example, 25 wt%, 30 wt%, 35 wt%, 40 wt%, or 45 wt%, etc.

[0100] By combining propylene glycol and glycerin, a lower aerosol release temperature can be achieved while maintaining sufficient smoke release. Using encapsulated aerosol-generating materials allows the aerosol-generating product to achieve uniform and sufficient smoke release at lower heating temperatures, thereby reducing the energy consumption required for heating during inhalation, minimizing the release of harmful substances, and improving the inhalation experience.

[0101] In some embodiments, to enhance the flavor profile, other ingredients may be added to the core material of the aerosol-generating capsule 104, including but not limited to one or more of the following: flavorings, extracts, nicotine, nicotine salts, etc. For example, in some embodiments, the core material further includes 0.1–20 wt% flavorings and / or extracts by weight; in some embodiments, the core material further includes 0.1–20 wt% nicotine and / or nicotine salts by weight. Extracts may be animal or plant extracts, such as musk, ambergris, tea extract, monk fruit extract, etc., and the flavor can be adjusted as needed.

[0102] It should be noted that the composition and ratio of the smoke-generating agent in the multiple aerosol generating capsules 104 may be the same or different, and this embodiment of the present invention does not limit this.

[0103] In some embodiments, the core material of the aerosol generating capsule 104 may further include an oily formulation and a structural agent; the structural agent includes cellulose and / or cellulose derivatives, low molecular weight lipids, and surfactants. The core material can be a paste, a colloid, or a solid-liquid mixture at room temperature. The combination of cellulose and / or cellulose derivatives and low molecular weight lipids facilitates the formation of a network structure in the oily formulation that is conducive to the dispersion and fixation of propylene glycol and glycerol. The surfactants help form an oil film between the core material and the shell of the aerosol generating capsule 104, thereby helping to form the shell to encapsulate the core material. The core material formed by propylene glycol and glycerol, the oily formulation, and the structural agent is in the form of a paste, a colloid, or a solid-liquid mixture at room temperature (25°C), which can help achieve stable encapsulation of the core material by the shell of the aerosol generating capsule 104.

[0104] It should be clarified that the use of oily agents and structural agents in the core material is only one specific means of coating the smoke-generating agent and other components. In order to coat the smoke-generating agent and other components in the core material, known coating methods in the existing technology can also be used, such as coating and spheroidizing method, freeze coating method, coagulation method, etc.

[0105] In some embodiments, the shell material of the aerosol generating capsule 104 may be a thermosetting resin, such as epoxy resin cured under a photoinitiator.

[0106] In some embodiments, the shell material of the aerosol generating capsule 104 may include, but is not limited to, any one or more of the following colloidal substances: plant gums, animal gums, microbial gums, starch, starch modifiers, etc. The animal gums may be, for example, gelatin, fish glue, or chitosan, etc., and the plant gums may be, for example, carrageenan, sodium alginate, gellan gum, or tamarind gum, etc.

[0107] To facilitate shaping during processing, the shell material may further include a curing agent. The curing agent may be a polyol, specifically glycerol or sorbitol.

[0108] In some embodiments, the shell material may further include a reinforcing agent, such as a metal salt, specifically calcium chloride, potassium chloride, calcium carbonate, calcium phosphate, or calcium dihydrogen phosphate.

[0109] The thickness of the shell of the aerosol generating capsule 104 can be, for example, 50 to 150 μm, specifically 60 μm, 80 μm, 100 μm, 120 μm, 140 μm or 150 μm.

[0110] In one embodiment of preparing aerosol-generating capsules 104, raw materials comprising propylene glycol and glycerin, an oily preparation, and a structuring agent are mixed to obtain a core material; a coating liquid is prepared using raw materials comprising a colloidal substance, a curing agent, and water; and then the coating liquid is used to coat the core material to prepare the aerosol-generating capsule. The method of preparing capsules by coating the core material with the coating liquid can employ some existing encapsulation methods, such as concentric tube dripping.

[0111] The shell of the aerosol generating capsule 104 can burst at a certain heating temperature, releasing the core material to generate aerosol.

[0112] The release temperature of the aerosol-generating capsule 104 is typically lower than the smoking temperature of reconstituted tobacco leaves or shredded tobacco containing smoking agents such as glycerin or propylene glycol. In some embodiments, the heating release temperature of the aerosol-generating product can be 180–280°C; in other embodiments, the heating release temperature of the aerosol-generating product can be 220–260°C, for example, 220°C, 230°C, 240°C, 250°C, or 260°C, etc. Therefore, compared to existing HNB products, the aerosol-generating product provided in this embodiment of the invention can reduce the waiting time for heating to produce smoke and is beneficial for reducing the energy consumption of heated smoking devices. The amount of aerosol released by the aerosol-generating capsule 104 will vary at different heating temperatures.

[0113] Furthermore, as the heating temperature continues to rise, the amount of aerosol released from the aerosol generating capsule 104 gradually increases. Moreover, when a certain temperature is reached, such as 300°C, if other aerosol-releasing materials are mixed in, these materials, excluding the aerosol generating capsule 104, also begin to produce vapor, further enhancing the user's vaping experience. Additionally, flavorings and other ingredients can be added to the mixed aerosol-releasing materials to enrich the aerosol flavor and better meet the diverse vaping preferences of different users.

[0114] In some embodiments, to enhance the flavor profile, one or more excipient capsules may be added to the aerosol matrix section 101. That is, the aerosol matrix section 101 includes the aforementioned aerosol-generating capsule 104 and the excipient capsules. In specific implementations, the excipient capsules may include any one or more of the following: flavor capsules, extract capsules, nicotine capsules, nicotine salt capsules, etc. In some embodiments, multiple ingredients may be mixed together and placed in the same excipient capsule; this is not limited in this embodiment of the invention.

[0115] In some embodiments, the volume ratio of the excipient capsules in the aerosol generating matrix section 101 to the aerosol generating capsules 104 can be 10:1 to 1:10, so as to better meet the personalized needs of different users for the smoking experience.

[0116] In specific implementations, the shell material, particle size, and shape of the excipient capsules may be the same as or different from the shell material, particle size, and shape of the aerosol generating capsules 104; this embodiment of the invention does not limit this. Furthermore, the distribution of the excipient capsules and the aerosol generating capsules 104 within the aerosol generating matrix section 101 may be uniform or non-uniform; this embodiment of the invention does not limit this.

[0117] The aerosol-generating products provided in this invention are highly versatile and can be adapted to various heating devices, such as needle-type heating devices, plate-type ceramic heating devices, air-heated devices, and microwave-heated devices.

[0118] like Figure 5 The diagram shown is a schematic diagram of the aerosol generation product provided in an embodiment of the present invention assembled into a central heating smoke device.

[0119] This example uses a needle-type heated smoke device and Figure 1 Taking the aerosol-generated product 10 shown below as an example, the following is combined with... Figure 1 A brief explanation of its heating process is provided.

[0120] During heating, the aerosol generating product 10 is inserted into the smoking device QC. The needle heating element QC1 in the smoking device QC is inserted into the aerosol generating matrix section 101. The power supply and control unit QC2 controls the needle heating element QC1 to start heating. When the temperature reaches a certain level, such as 180°C, the aerosol generating capsule 104 in the aerosol generating matrix section 101 begins to release, generating smoke. The smoke passes through the airflow channel on the limiting member 102 and reaches the filter section 103. The filter section 103 filters the smoke before it reaches the smoker's mouth.

[0121] In some embodiments, a sensor may also be provided in the aerosol generating matrix section 101 to adapt it to electromagnetic induction heating smoke appliances.

[0122] like Figure 6 The diagram shown is a structural schematic of an aerosol-generated product provided in an embodiment of the present invention.

[0123] In this example, the aerosol generating article 20 includes an aerosol generating matrix section 201, which includes a plurality of aerosol generating capsules 204. The aerosol generating article 20 also includes a sealing element 205, a limiting element 202, and a filter section 203.

[0124] Among them, the aerosol generation matrix section 201, the limiting component 202, and the filtration section 203 and Figure 1 The aerosol generation matrix section 101, limiting member 102, and filter section 103 shown in the example are similar and will not be described again here.

[0125] In this example, the sealing element 205 is a cellulose acetate rod or a cotton swab, which is used to seal one end of the section near the aerosol generation matrix.

[0126] Similarly, in this example, the aerosol-generating capsule can be tightly packed or loosely packed within the aerosol-generating matrix segment. For example... Figure 7 As shown, in a non-tightly packed condition, the vertical static height h of the aerosol generating capsule 204 within the aerosol generating matrix section 201 is less than the length H of the aerosol generating matrix section 201, i.e., h <H。

[0127] like Figure 8 The diagram shown is another structural schematic of the aerosol-generated product provided in an embodiment of the present invention.

[0128] In this example, the aerosol generating article 30 includes an aerosol generating matrix section 301, which includes a plurality of aerosol generating capsules 304. The aerosol generating article 30 also includes a sealing element 305, a limiting element 302, and a filter section 303.

[0129] The aerosol generating matrix section 301 and the limiting member 302 are enclosed in the same tube, and can be enclosed in the same tube or a different tube from the filter section 303.

[0130] In this example, there is a certain gap between the limiting member 302 and the inner wall of the tube, which can serve as an airflow channel. Moreover, the limiting member 302 can move easily within the tube. That is, the position of the limiting member 302 is not fixed, but can move within a certain spatial range, such as rotating along the axis or moving left and right along the axis.

[0131] The two axial ends of the limiting member 302 are adjacent to the aerosol generating matrix section 301 and the filter section 303, respectively. In this embodiment, the limiting member 302 can be made of rolled sheet material, such as rolled paper or rolled polylactic acid sheet material. There are gaps between the center of the roll or between the winding loops, allowing the aerosol generated by the aerosol generating matrix section 301 to reach the filter section through these gaps or the gaps between the limiting member 302 and the inner wall of the tube. The aerosol generating capsule 304 cannot pass through either the gaps within the limiting member 302 itself or the gaps between the limiting member 302 and the inner wall of the tube.

[0132] Among them, the aerosol generation matrix section 301 and the filtration section 303 and Figure 1 The aerosol generation matrix section 101 and the filtration section 103 in the example shown are similar and will not be described again here.

[0133] The multiple aerosol generating capsules 304 filling the aerosol generating matrix segment 301 can be tightly packed or loosely packed. For example... Figure 9As shown, in a non-tightly packed condition, the vertical static height h of the aerosol generating capsule 304 within the aerosol generating matrix section 301 is less than the length H of the aerosol generating matrix section 301, i.e., h <H。

[0134] In some embodiments, one or more pores may be provided on the tube body corresponding to the aerosol generating matrix section. The multiple pores may be distributed on part or all of the tube body corresponding to the aerosol generating matrix section. This design can effectively reduce suction resistance and enhance the suction effect.

[0135] In some embodiments, a heat-conducting layer may be provided on the inner surface of the tube corresponding to the section of the aerosol generating matrix. The length of the heat-conducting layer may be greater than, less than or equal to the length of the aerosol generating matrix section to enhance heat transfer efficiency and reduce heating waiting time during suction.

[0136] In some embodiments, a heat-conducting layer may be provided on the entire inner surface of the tube to facilitate manufacturing and improve the flame-retardant effect.

[0137] The heat-conducting layer can be made of metal foil, preferably aluminum foil, which not only conducts heat but also acts as a flame retardant.

[0138] The aerosol-generating capsules used in the embodiments of the present invention can be prepared by a variety of methods, such as one of the following methods.

[0139] Heat 40 parts by weight of sunflower seed oil to 100°C, and while stirring, add 7.1 parts by weight of ethyl cellulose, 1.4 parts by weight of beeswax, and 2.1 parts by weight of palm wax. Dissolve and mix evenly, cool to 60°C, and add 24 parts by weight of propylene glycol, 16 parts by weight of glycerol, 2.4 parts by weight of surfactant (prepared from Tween 80 and glyceryl monooleate in a weight ratio of 1:9), 5 parts by weight of mango flavoring, and 2 parts by weight of nicotine salt. Stir evenly to complete the preparation of the core material.

[0140] Add 5 parts by weight of carrageenan and 3 parts by weight of gellan gum to 82 parts by weight of purified water, and heat while stirring at a temperature of 60-90°C to form a homogeneous solution. Add 10 parts by weight of glycerol and stir until homogeneous to prepare the film solution.

[0141] Using a concentric dropper, the core material (inner layer) and film liquid are dripped into the cooling liquid (MCT) while the temperature is controlled at 10℃~25℃ to form wet capsules. The capsules are then stored at -10℃~10℃ for 10 hours and dried at 20~30℃ and 20%~50% humidity to obtain capsule products with a particle size of 2mm and a wall thickness of 70μm.

[0142] The aerosol-generating products provided in this embodiment of the invention can have different processing steps depending on their structure.

[0143] For example, one processing method is as follows: a paper tube with an outer diameter of 9.0 mm, a length of 45 mm, and a sealed bottom is made, and a hole is made in an area 10 mm away from the seal. 0.2 g of aerosol is filled into the open end to form a capsule, and then a 28 mm hollow cellulose acetate filter rod is inserted.

[0144] For example, one processing method is as follows: make a paper tube with an outer diameter of 9.0 mm and a length of 45 mm without sealing at both ends, punch holes in an area 10 mm away from the sealing, and then fill it with a 7 mm cellulose acetate rod, a 0.2 g aerosol generating capsule, and a hollow 23 mm cellulose acetate rod in sequence.

[0145] When manufacturing the aerosol-generating products provided in the embodiments of the present invention, products with different tastes and inhalation effects can be made by adjusting parameters such as the length of the aerosol-generating matrix segment, the aerosol-generating capsule arrangement density, and the particle size, so as to meet the needs and experiences of different smokers.

[0146] To further verify the suction experience of products with different design parameters, some related tests were also conducted, mainly the following.

[0147] (1) Comparative test of taste and draw resistance when the aerosol generation matrix segment has different lengths

[0148] The diameter of the aerosol-generating capsule was set to 1.5–2 mm, the total length of the aerosol-generating matrix section and the filter section was 38 mm, the length of the limiting component was 7 mm, and the total length of the aerosol-generating product was 45 mm. By adjusting the length parameters of the CA (filter section) and the aerosol-generating matrix section of the aerosol-generating product, different aerosol-generating products were obtained. The results of the test on the suction resistance and inhalation experience of the aerosol-generating products with different parameters are shown in Table 1.

[0149] Table 1

[0150]

[0151] Scoring criteria: Smoke volume, aroma, stability, satisfaction, aftertaste, and oral residue. The best score for any single item is 10 points, and the worst score is 0 points.

[0152] (2) Comparison test of suction resistance and taste when the filling height ratio of aerosol-generated capsules is different

[0153] The fill-to-height ratio is defined as the ratio of the static height of the stacked aerosol-generating capsules after the aerosol-generating product is upright to the length of the aerosol-generating matrix section. The fill-to-height ratio is determined by the amount of aerosol-generating capsules; the less the amount of capsules, the smaller the fill-to-height ratio.

[0154] The length of the aerosol generation matrix segment was set to 10 mm, and different amounts of aerosol generation capsules were filled to verify its relationship with the draw resistance, smoke volume, and sensory evaluation of the aerosol generation products. The experimental results are shown in Table 2 below:

[0155] Table 2

[0156]

[0157] The scoring criteria are: smoke volume, aroma, stability, satisfaction, aftertaste, and oral residue. The best score for any single item is 10 points, and the worst score is 0 points.

[0158] (3) Comparison test of taste of aerosol-generated capsules with different particle sizes

[0159] With a filling height ratio of 80% and an aerosol generation matrix section length of 10 mm, aerosol generation capsules of different particle sizes were filled. The draw resistance, smoke volume, and sensory evaluation were tested. The experimental results are shown in Table 3 below.

[0160] Table 3

[0161]

[0162]

[0163] The scoring criteria are: smoke volume, aroma, stability, satisfaction, aftertaste, and oral residue. The best score for any single item is 10 points, and the worst score is 0 points.

[0164] (4) Taste comparison test of tube hole setting

[0165] The two groups of aerosol generating products use the same structural design parameters. They are filled with aerosol generating capsules of the same particle size and number in the aerosol generating matrix section, and the filling height ratio of the aerosol generating capsules is the same. The difference is that the first group of aerosol generating products does not have channels on the corresponding tube body of the aerosol generating matrix section, while the second group of aerosol generating products has 21 channels with a diameter of 0.08 mm on the corresponding tube body of the aerosol generating matrix section at a distance of 5 mm from the port.

[0166] The absorption resistance and sensory evaluation of the two groups of aerosol-generated products were conducted, and the experimental test data are shown in Table 4 below:

[0167] Table 4

[0168]

[0169] In the above tests, the best score for each of the following categories—aroma quantity, aroma quality, stability, satisfaction, aftertaste, and oral residue—is 10, and the worst score is 0.

[0170] (5) Comparative test of the thermal conductive material setting of the tube body

[0171] Using the same smoking device and heating temperature, the smoke volume and sensory evaluation were compared between devices with and without heat-conducting materials and different aerosol-generating materials (capsules, tobacco particles). The details are as follows:

[0172] The aerosol-generated product sample has a length of 45 mm, an aerosol-generating matrix section length of 10 mm, a particle size of 1.5–2 mm for the aerosol-generated capsules and tobacco particles, and a filling height ratio of 80%.

[0173] Based on the above sample parameters, the samples were subjected to heating tests. The results of this group of experiments are shown in Table 5 below:

[0174] Table 5

[0175]

[0176] Scoring criteria: Smoke volume, aroma, stability, satisfaction, aftertaste, and oral residue. The best score for any single item is 10 points, and the worst score is 0 points.

[0177] As can be seen from the test data in Table 5, compared with using tobacco pellets and a heat-conducting layer inside the tube, using capsules and a heat-conducting layer inside the tube can achieve better smoke generation and sensory experience.

[0178] The smoke concentration was tested using an electronic cigarette device, and the results are shown in Table 6 below:

[0179] Table 6

[0180]

[0181] The test results from the aforementioned experimental instruments further verified the above conclusions.

[0182] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
