Description

Technical Field

[0001] This application relates to the field of novel tobacco technology, and in particular to an aerosol-generating product and its preparation method, as well as an aerosol-generating system. Background Technology

[0002] Heated tobacco products, as an important component of new cigarette products, typically include a filter section, a cooling support section, and a tobacco section. By heating the tobacco material in the tobacco section at a low temperature and controlling the heating temperature to prevent combustion, they can effectively reduce harmful substances such as tar produced by the combustion of traditional cigarettes.

[0003] Heated tobacco products typically involve adding flavorings to tobacco segments during the production process. The weight of the flavorings increases the mass of the tobacco segments, which leads to the flavorings being mistakenly taxed as part of the tobacco material in some regions, resulting in higher costs. Furthermore, tobacco segments that have absorbed sufficient flavorings can contaminate the walls of heated tobacco products.

[0004] This problem can be addressed by applying greaseproof paper to the inner wall of the paper tube and reducing the amount of flavoring used. However, while applying greaseproof paper can slow down the leakage of flavoring and smoking materials for a certain period, this effect is often short-lived. In addition, reducing the amount of flavoring used will reduce the aroma concentration of heated tobacco products, affecting the user experience. Summary of the Invention

[0005] The purpose of this application is to provide an aerosol-generating product and its preparation method, as well as an aerosol-generating system, which aims to solve the problems of high cost and pipe wall pollution of existing heated non-combustible cigarette products.

[0006] To achieve the above objectives, this application provides an aerosol generating article, comprising an aerosol substrate segment, wherein the aerosol substrate segment includes a smoke-generating segment and a fragrance-carrying segment disposed along the length direction of the aerosol generating article, and a coating layer at least covering the outer peripheral surfaces of the smoke-generating segment and the fragrance-carrying segment; the fragrance-carrying segment includes a fusible solid carrier and a fragrance attached to the fusible solid carrier.

[0007] In some embodiments, the aerosol generating article further includes a first component disposed between the smoke-generating section and the fragrance-carrying section, and the first component has a first airflow channel extending through its length.

[0008] In some embodiments, the core material of the smoke-generating section is granular, sheet-like, or filamentous.

[0009] In some embodiments, the aerosol-generating article further includes a breathable sealing layer that seals the distal lip of the covering layer.

[0010] In some embodiments, the fusible solid carrier comprises polyethylene glycol and / or carnauba wax;

[0011] The polyethylene glycol is selected from at least one of polyethylene glycol 200, polyethylene glycol 300, polyethylene glycol 400, polyethylene glycol 600, polyethylene glycol 800, polyethylene glycol 1000, polyethylene glycol 1500, polyethylene glycol 2000, polyethylene glycol 3000, polyethylene glycol 4000, polyethylene glycol 6000, polyethylene glycol 8000, polyethylene glycol 10000, and polyethylene glycol 20000.

[0012] In some embodiments, the aerosol generating article further includes a filter section and a cooling section, the coating layer further covers the outer periphery of the filter section, and the cooling section is at least a partial cavity defined by the filter section, the aerosol substrate section and the coating layer.

[0013] In some embodiments, the aerosol generating article further includes a second fastener covered by the coating layer and located between the cooling section and the aerosol substrate section, the second fastener having a second airflow channel extending through its length.

[0014] In some embodiments, the fragrance-carrying section is located on the side of the smoke-generating section near the second firmware.

[0015] In some embodiments, the smoke-generating section is located on the side of the fragrance-carrying section near the second firmware.

[0016] This application also provides a method for preparing the above-mentioned aerosol-generating article, comprising:

[0017] Provide an empty tube with one end sealed;

[0018] A smoke-generating section and an aroma-carrying section are inserted into the open end of the empty tube to obtain the aerosol-generated product.

[0019] In some embodiments, the step of inserting a smoke-generating section and a fragrance-carrying section into the open end of the empty tube to obtain the aerosol-generating product includes:

[0020] One of the smoke-generating section and the fragrance-carrying section, the first fastener, the other smoke-generating section and the fragrance-carrying section, and the second fastener are sequentially inserted into the open end of the empty tube;

[0021] Insert the filter section and set a gap between it and the second firmware;

[0022] When the fragrance-carrying segment is inserted into the empty tube, it includes injecting a molten, fusible solid carrier with fragrance attached into the empty tube, or inserting a shaped fusible solid carrier with fragrance attached.

[0023] This application also provides an aerosol generation system, including the above-described aerosol generation article and a heating device adapted to the aerosol generation article.

[0024] Compared with related technologies, the beneficial effects of this application include:

[0025] The aerosol substrate segment of the aerosol generating product provided in this application includes a smoke-generating segment and a fragrance-carrying segment. The fragrance-carrying segment includes a fusible solid carrier and a fragrance. The fusible solid carrier has a molten state and a solid state. It is solid at room temperature and molten after heating. At room temperature, the fragrance is "locked" in the solid medium, making the fragrance-carrying segment and the smoke-generating segment two independent segments. This can avoid the phenomenon of fragrance contaminating the tube wall during the storage of the aerosol generating product. Furthermore, since the fragrance-carrying segment and the smoke-generating segment are isolated, the weight of the smoke-generating segment can be reduced, thereby reducing costs.

[0026] In addition, isolating the fragrance-carrying section from the smoke-generating section allows the smoke-generating section to remain as dry as possible and free from moisture; the aerosol-generating product can also adsorb more fragrance without increasing the weight of the smoke-generating section, resulting in a richer aroma during inhalation; the aerosol-generating product can release the aroma more evenly, preventing the aroma from being released too quickly at the beginning of heating; the fragrance in the aerosol-generating product is less volatile, thus locking in the aroma for a longer period; and after the fragrance-carrying section melts, the fragrance begins to evaporate upon heating, causing the fragrance-carrying section to shift to a certain position. The space occupied by the fragrance-carrying section can act as a cooling channel, indirectly extending the cooling section and improving the cooling effect.

[0027] The method for preparing aerosol-generated products provided in this application adopts a filling process, which is simple to operate and easy to mass-produce.

[0028] The aerosol generation system provided in this application generates aerosols with a rich aroma and good cooling effect. Attached Figure Description

Detailed Implementation

[0036] As used in this article:

[0037] "Prepared from" is synonymous with "comprising". The terms "comprising", "including", "having", "containing", or any other variations thereof as used herein are intended to cover non-exclusive inclusion. For example, a composition, step, method, article, or apparatus that includes the listed elements is not necessarily limited to those elements, but may include other elements not expressly listed or elements inherent to such composition, step, method, article, or apparatus.

[0038] The conjunction "composed of..." excludes any unspecified elements, steps, or components. If used in a claim, this phrase makes the claim closed, excluding materials other than those described, except for associated conventional impurities. When the phrase "composed of..." appears in a clause of the body of a claim rather than immediately following it, it limits only the elements described in that clause; other elements are not excluded from the claim as a whole.

[0039] When a quantity, concentration, or other value or parameter is expressed as a range, a preferred range, or a range defined by a series of upper and lower preferred values, this should be understood as specifically disclosing all ranges formed by any pair of any upper or preferred value with any lower or preferred value, regardless of whether the range is disclosed individually. For example, when the range “1–5” is disclosed, the described range should be interpreted as including ranges “1–4”, “1–3”, “1–2”, “1–2 and 4–5”, “1–3 and 5”, etc. When numerical ranges are described herein, unless otherwise stated, the range is intended to include its endpoints and all integers and fractions within that range.

[0040] "And / or" is used to indicate that one or both of the described situations may occur, for example, A and / or B includes (A and B) and (A or B).

[0041] In the production of heated tobacco products, flavorings are added to the tobacco segments. The weight of the flavorings increases the mass of the tobacco segments, and tobacco segments that have absorbed a sufficient amount of flavorings can also contaminate the tube walls of heated tobacco products.

[0042] To address the problems of the prior art, this application provides an aerosol generating article 100, such as... Figure 1 and Figure 2 As shown, it includes an aerosol substrate segment 30, which includes a smoke-generating segment 32 and a fragrance-carrying segment 34 disposed along the length direction of the aerosol-generating article 100, and a coating layer 60 covering at least the outer peripheral surfaces of the smoke-generating segment 32 and the fragrance-carrying segment 34; the fragrance-carrying segment 34 includes a fusible solid carrier and fragrance attached to the fusible solid carrier.

[0043] The covering layer 60 is made of a material with sufficient hardness to encapsulate and support the filler without deformation. The material of the covering layer 60 can be a paper tube, aluminum foil tube, aluminum foil-paper tube, ceramic tube, silicone rubber tube, heat-resistant resin tube, etc. The order of the smoke-generating section 32 and the fragrance-carrying section 34 is not limited. The smoke-generating section 32 can be located upstream or downstream of the fragrance-carrying section 34. The upstream end in the aerosol suction direction is the distal lip end, and the downstream end in the aerosol suction direction is the proximal lip end.

[0044] The smoke-generating section 32 is a core material, such as tobacco raw materials, herbs, or fiber paper substrates that have absorbed smoke-generating agents. The core material can be in the form of granules, pulp, filaments, or flakes. The core material of this application can be granules and pulp, which is beneficial to the filling process.

[0045] The fragrance carrier segment 34 includes a fusible solid carrier and a fragrance attached to the fusible solid carrier. The fragrance can be a solid fragrance or a liquid fragrance. The liquid fragrance is adsorbed onto the fusible solid carrier, and the solid fragrance is encapsulated within the fusible solid carrier. A smoke-generating agent may also be mixed into the fusible solid carrier. The smoke-generating agent is selected from propylene glycol, glycerol, triacetin, or diacetin, etc. The fusible solid carrier has a molten state and a solid state; it is solid at room temperature and becomes a molten liquid after heating.

[0046] Therefore, when the aerosol generating product 100 is not used at room temperature, the fragrance-carrying section 34 is solid, and the fragrance is "locked" in the solid medium, which can avoid the phenomenon of fragrance contaminating the tube wall. In addition, the fragrance is not added to the core material, so it will not increase the weight of the smoke-generating section 32 and reduce the cost. When the aerosol generating product 100 is heated and used, the fragrance-carrying section 34 is a molten liquid, thereby releasing the fragrance.

[0047] The aerosol substrate segment 30 of the aerosol generating article 100 provided in this application includes a smoke-generating segment 32 and a fragrance-carrying segment 34. The fragrance-carrying segment 34 includes a fusible solid carrier and a fragrance. The fusible solid carrier has a molten state and a solid state. It is solid at room temperature and molten after heating. When not in use at room temperature, the fragrance is "locked" in the solid medium, so that the fragrance-carrying segment 34 and the smoke-generating segment 32 are two independent segments. This can avoid the phenomenon of fragrance contaminating the tube wall. Furthermore, since the fragrance-carrying segment 34 and the smoke-generating segment 32 are isolated, the weight of the smoke-generating segment 32 can be reduced to reduce costs.

[0048] In addition, isolating the fragrance-carrying section 34 from the smoke-generating section 32 allows the smoke-generating section 32 to remain as dry as possible and free from moisture; the fragrance-carrying section 34 can also absorb more fragrance without increasing the weight of the smoke-generating section 32, making the aroma more intense during inhalation; the fragrance-carrying section 34 can release the aroma more evenly, preventing the aroma from being released too quickly at the beginning of heating; the fragrance in the fragrance-carrying section 34 is not easily volatile, thus locking in the aroma for a longer period of time; and after the fragrance-carrying section 34 melts, the fragrance begins to evaporate upon heating, and the fragrance-carrying section 34 will undergo a certain degree of relocation. The space occupied by the fragrance-carrying section 34 can serve as a cooling channel, indirectly extending the cooling section and improving the cooling effect.

[0049] In some embodiments, the fusible solid carrier is solid at room temperature and liquid at temperatures of 60°C and above. The fusible solid carrier includes one or more of polyethylene glycol and carnauba wax. Both polyethylene glycol and carnauba wax are phase change substances, solid at room temperature and liquid in a molten state after heating. The fusible solid carrier is uniformly mixed with fragrance in a molten state. The fragrance includes aroma-producing substances, such as various fruity and minty flavorings.

[0050] Polyethylene glycol is an ethylene glycol polymer containing α,ω-terminated hydroxyl groups. In some embodiments, the polyethylene glycol is selected from at least one of polyethylene glycol 200, polyethylene glycol 300, polyethylene glycol 400, polyethylene glycol 600, polyethylene glycol 800, polyethylene glycol 1000, polyethylene glycol 1500, polyethylene glycol 2000, polyethylene glycol 3000, polyethylene glycol 4000, polyethylene glycol 6000, polyethylene glycol 8000, polyethylene glycol 10000, and polyethylene glycol 20000.

[0051] In some embodiments, the length of the fragrance-carrying segment 34 (the dimension in the length direction of the aerosol-generating article 100) is 5-13 mm, for example, it can be 5 mm, 5.5 mm, 5.6 mm, 5.7 mm, 5.8 mm, 5.9 mm, 6.0 mm, 6.1 mm, 6.2 mm, 6.3 mm, 6.4 mm, 6.5 mm, 6.6 mm, 6.7 mm, 6.8 mm, 6.9 mm, 7.0 mm, 7.5 mm, 8.0 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm or 13 mm, and the mass of the resulting fragrance-carrying segment 34 is about 100 mg, for example, 80 mg-120 mg.

[0052] In some embodiments, the length ratio of the fragrance-carrying section 34 to the smoke-generating section 32 is 0.4 to 0.8, for example, it can be 0.4, 0.5, 0.6, 0.7 or 0.8. The total length of the fragrance-carrying section 34 and the smoke-generating section 32 is not greater than 25 mm.

[0053] Within the aforementioned range, the ratio of the length of the aroma-carrying section 34 to the length of the smoke-generating section 32 ensures suitable aroma concentration, appropriate draw resistance, and cost control for the aerosol product 100. If the ratio of the length of the aroma-carrying section 34 to the length of the smoke-generating section 32 is too high, the weight cannot be guaranteed, resulting in distortion of the aroma of the smoke-generating section itself, an unnatural aerosol aroma, and increased draw resistance; if the ratio of the length of the aroma-carrying section 34 to the length of the smoke-generating section 32 is too low, the weight is too high, and the cost is too high.

[0054] The aerosol generating article 100 of this application further includes a first fastener 40, which is disposed between the smoke-generating section 32 and the fragrance-carrying section 34. The first fastener 40 has a first airflow channel extending through its length, and the fragrance-carrying section 34 is heated and melted. Since the fragrance-carrying section 34 is in a molten state after heating, the first fastener 40 serves two purposes: firstly, it limits the flow of the molten fragrance-carrying section 34 towards the lip end; secondly, it allows aerosols to pass through, thus also providing a certain degree of cooling and filtration. Therefore, the first fastener 40 can be a structure with circumferential grooves or a central hole, and can also be made of a breathable material, such as plant fiber, silicone, silica, or other polymer materials.

[0055] In some embodiments, please refer to Figure 1 and Figure 2The covering layer 60 can be sealed at its distal end by the sealing layer 62 to facilitate the insertion of the smoke-generating section 32 and the fragrance-carrying section 34. The sealing layer 62 is a breathable structure, and the sealing layer 62 can be, for example, perforated aluminum foil, highly breathable paper, coated paper, or high-temperature resistant plastic film; the outer diameter of the tubular covering layer 60 can be 5mm-20mm, for example 6mm-7mm, and the wall thickness can be 0.1mm-1mm. The covering layer 60 can be a thick paper tube with a wall thickness of 0.15mm or greater, and a length of 30mm-100mm, for example 45mm or 50mm, covering the entire outer periphery of the aerosol generating product 100.

[0056] In some embodiments, please refer to Figure 1 and Figure 2 The aerosol generating article 100 further includes a filter section 10, a cooling section 20, an aerosol substrate section 30, a cooling section 20 and a filter section 10 arranged sequentially from upstream to downstream along the aerosol suction direction, and the coating layer 60 also covers the outer periphery of the filter section 10, and the cooling section 20 is at least a partial cavity defined by the filter section 10, the aerosol substrate section 30 and the coating layer 60.

[0057] The cooling section 20 provides space for aerosol mixing and cooling, cooling the aerosol generated by the aerosol substrate section 30 to meet the suction requirements. The cooling section 20 can be an empty tube or other perforated tubular element, or a structure and material similar to the first fastener 40.

[0058] The filter section 10 is used to filter aerosols and further cool or filter and adsorb harmful substances. The filter section 10 can be a cellulose acetate rod, a polypropylene rod, a polylactic acid rod, or a paper filter rod.

[0059] In some embodiments, please refer to Figure 1 and Figure 2 The aerosol generating article 100 further includes a second fastener 50 covered by the coating layer 60 and located between the cooling section 20 and the aerosol substrate section 30, the second fastener 50 having a second airflow channel extending through its length.

[0060] The second firmware 50 functions similarly to the first firmware 40, serving both a positioning function and allowing aerosols to pass through, thus also providing some cooling and filtration. Therefore, the structure and materials of the second firmware 50 can be identical to those of the first firmware 40.

[0061] In some embodiments, the lengths (dimensions along the length of the aerosol-generating article 100) of the first firmware 40 and the second firmware 50 are each independently 3.0-7.0 mm, for example, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, 6.6 mm, 6.7 mm, 6.8 mm, 6.9 mm, or 7.0 mm, preferably 3.0 mm-5.5 mm. The lengths of the first firmware 40 and the second firmware 50 within the above range can simultaneously fulfill their positioning, ventilation, adsorption, and filtration functions. If the lengths of the first firmware 40 and the second firmware 50 are too short, their adsorption effect will be reduced, the manufacturing difficulty of the first firmware 40 and the second firmware 50 will increase, and the corresponding cost will also increase. In addition, the installation difficulty of each firmware will also increase. If the lengths of the first firmware 40 and the second firmware 50 are too long, the adsorption effect will be enhanced, the suction resistance of the aerosol generating product 100 will also increase, the inhalation experience will be worse, and the aroma and smoke volume will decrease. In addition, increasing the firmware length will increase the cost of the firmware, and the cost of the aerosol generating product 100 will also increase.

[0062] In some embodiments, please refer to Figure 1 The fragrance-carrying section 34 is located on the side of the smoke-generating section 32 near the second firmware 50, that is, the fragrance-carrying section 34 is located at one end near the cooling section 20, and the first firmware 40 and the second firmware 50 are respectively located on both sides of the fragrance-carrying section 34. Figure 1 As can be seen, the structure of the aerosol generating product 100 in this embodiment, from upstream to downstream in the aerosol suction direction, consists of a sealing layer 62, a smoke-generating section 32, a first fastener 40, a fragrance-carrying section 34, a second fastener 50, a cooling section, and a filter section 10. The first fastener 40 is provided downstream of the smoke-generating section 32 to position the fragrance-carrying section 34. After the fragrance-carrying section 34 becomes solid, the second fastener 50 is added downstream of it for positioning, preventing the molten fragrance-carrying section 34 from tilting and potentially flowing into the filter section 10 during the consumer's heating and use.

[0063] In some embodiments, please refer to Figure 2 The smoke-generating section 32 is located on the side of the fragrance-carrying section 34 near the second fastener 50, that is, the smoke-generating section 32 is located at one end near the cooling section 20, and the first fastener 40 and the second fastener 50 are respectively located on both sides of the smoke-generating section 32. Figure 2As can be seen, the structure of the aerosol generating product 100 in this embodiment, from upstream to downstream in the aerosol suction direction, consists of a sealing layer 62, a fragrance-carrying section 34, a first fastener 40, a smoke-generating section 32, a second fastener 50, a cooling section 20, and a filter section 10. The first fastener 40 is set downstream of the fragrance-carrying section 34 to position the fragrance-carrying section 34. The second fastener 50 is set downstream of the smoke-generating section 32 to isolate and position the core material of the smoke-generating section 32.

[0064] This application also provides a method for preparing the above-mentioned aerosol-generating product. Please refer to [link / reference needed]. Figure 3 ,include:

[0065] S100: Provides an empty tube with one end sealed.

[0066] The hollow tube, or tubular covering layer 60, is made of a material with sufficient thickness or hardness to enclose and support the filler without deformation. The material of the hollow tube can be thick paper tube, aluminum foil tube, aluminum foil-paper tube, ceramic tube, silicone rubber tube, heat-resistant resin tube, etc. The covering layer 60 can be sealed by sealing its distal lip end with the sealing layer 62. The hollow tube can be sealed with perforated aluminum foil, high-permeability paper, laminated paper, or high-temperature resistant plastic film, etc. The sealed end can allow gas to enter; for example, air can be drawn in from the sealed end, or hot air can enter from the sealed end to heat the aerosol substrate section 30. For example, the hollow tube can be a thick paper tube with a wall thickness of 0.15 mm or greater and a length of 30 mm to 100 mm, such as 45 mm or 50 mm.

[0067] S200: Install the smoke-generating section and the incense-carrying section into the open end of the air pipe.

[0068] The order in which the smoke-generating section 32 and the fragrance-carrying section 34 are filled is not specifically limited. For example, the smoke-generating section 32 can be filled first and then the fragrance-carrying section 34 can be filled, or the fragrance-carrying section 34 can be filled first and then the smoke-generating section 32 can be filled.

[0069] The fragrance segment 34 can be injected in a molten state. After injection, the solidified fragrance segment 34 can be in the shape of a gel, or an irregular or regular solid such as granules or flakes. Alternatively, the fragrance segment 34 can be made using a mold first, and after the fragrance segment 34 is formed, it can be demolded and the solid fragrance segment 34 can be filled into the empty tube by applying external pressure.

[0070] The method for preparing aerosol-generated products provided in this application can be achieved by filling the sections into an empty tube in sequence to assemble the aerosol-generated products.
