Description

Technical Field

[0001] This application relates to the field of novel tobacco technology, and in particular to a heated non-combustible cigarette and its preparation method and aerosol generation system. Background Technology

[0002] Heated tobacco products are a new type of cigarette product that has emerged in recent years. Because they use an external heat source to heat and bake the cigarettes to release smoke, the release of harmful components is significantly reduced. Compared with traditional cigarettes, the safety of these products has been significantly improved, and they have gained market recognition.

[0003] Heated tobacco products typically involve adding flavorings to the tobacco segments. 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 a sufficient amount of flavorings can contaminate the walls of heated tobacco products.

[0004] This problem can be addressed by adding greaseproof paper or applying an greaseproof layer to the inner wall of the paper tube, as well as reducing the amount of flavoring used. However, while adding greaseproof paper or applying an greaseproof layer can slow down the leakage of flavoring and smoking materials for a certain period of time, 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 a heated non-combustible cigarette and its preparation method, as well as an aerosol generation system, in order to solve the problems of high cost and pipe wall pollution of existing heated non-combustible cigarettes.

[0007] In some embodiments, the fragrance-carrying section is disposed upstream or downstream of the smoke-generating section.

[0008] In some embodiments, the fusible solid carrier comprises polyethylene glycol and / or carnauba wax;

[0009] 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.

[0010] In some embodiments, the core material of the smoke-generating section is filamentous, sheet-like, or solid columnar.

[0011] In some embodiments, the first wrapping layer wraps the core segment, the cooling support segment, and the filter segment; the second wrapping layer wraps the sealing segment and the first wrapping layer.

[0012] In some embodiments, the second wrapping layer wraps the sealing section, the core section, and the cooling support section, and the first wrapping layer wraps the filter section and the second wrapping layer.

[0013] In some embodiments, a third wrapping layer is further included, wherein the first wrapping layer wraps the filter section, the second wrapping layer wraps the sealing section, and the third wrapping layer wraps the first wrapping layer, the second wrapping layer, and at least one segment of the fragrance-carrying section, the smoke-generating section, and the cooling support section.

[0014] This application also provides a method for preparing the above-mentioned heated non-combustible cigarette, comprising:

[0015] A fusible solid carrier is mixed with fragrance in a molten state to obtain a mixture;

[0016] The mixture is added to a mold to solidify, and then demolded to obtain a solid fragrance-carrying segment.

[0017] The aroma-carrying section is combined and twisted together with the sealing section, the smoke-generating section, the cooling support section, and the filter section to obtain the heated non-combustible cigarette.

[0018] In some embodiments, the fragrance-carrying section is combined and spliced ​​with the sealing section, the smoke-generating section, the cooling support section, and the filter section, including:

[0019] By combining two or three consecutive segments, including the filter segment, a first composite is obtained.

[0020] By combining three or two consecutive segments, including the blocking segment, a second composite is obtained;

[0021] The first composite and the second composite are joined together to obtain the heated non-combustible cigarette.

[0022] In some embodiments, the fragrance-carrying section is combined and spliced ​​with the sealing section, the smoke-generating section, the cooling support section, and the filter section, including:

[0023] The filtration section, the cooling support section, the fragrance-carrying section, and the smoke-generating section are combined to obtain a third composite.

[0024] The third composite material is joined to the sealing section to obtain the heated non-combustible cigarette.

[0025] In some embodiments, the fragrance-carrying section is combined and spliced ​​with the sealing section, the smoke-generating section, the cooling support section, and the filter section, including:

[0026] The sealing section, the fragrance-carrying section, the smoke-generating section, and the cooling support section are combined to obtain a fourth composite.

[0028] This application also provides an aerosol generation system, including the above-mentioned heated non-combustible cigarette and a heating device adapted to the heated non-combustible cigarette.

[0029] Compared with related technologies, the beneficial effects of this application include:

[0030] The heating non-combustible cigarette core segment provided in this application includes a flavor-carrying segment and a smoke-generating segment. The flavor-carrying segment includes a fusible solid carrier and flavorings attached to the fusible solid carrier. 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 flavorings are "locked" in the solid medium, making the flavor-carrying segment and the smoke-generating segment two independent segments. This can avoid the phenomenon of flavorings contaminating the tube wall during the storage of heating non-combustible cigarettes. Furthermore, since the flavor-carrying segment and the smoke-generating segment are isolated, the weight of the smoke-generating segment can be reduced, thereby reducing costs.

[0031] In addition, isolating the aroma-carrying section from the smoke-generating section allows the smoke-generating section to remain as dry as possible and avoid moisture; heated tobacco products can also absorb more fragrance without increasing the weight of the smoke-generating section, resulting in a richer aroma during smoking; heated tobacco products can release the aroma more evenly, preventing the aroma from being released too quickly at the beginning of heating; the fragrance in heated tobacco products is less volatile, allowing for a longer-lasting aroma lock; and after the aroma-carrying section melts, the fragrance begins to evaporate upon heating, causing the aroma-carrying section to shift to a certain position. The space occupied by the aroma-carrying section can act as a cooling channel, indirectly extending the cooling section and improving the cooling effect.

[0032] The method for preparing heated non-combustible cigarettes provided in this application involves first molding a mixture of a fusible solid carrier and a flavoring into a suitable size using a mold, and then integrating the cigarette into a cigarette using a composite twisting method after demolding. The method is simple to operate and easy to mass-produce.

[0033] The aerosol generation system provided in this application generates aerosols with a rich aroma and good cooling effect. Attached Figure Description

Detailed Implementation

[0050] As used in this article:

[0051] "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.

[0052] 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.

[0053] 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.

[0054] "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).

[0055] This application provides a heated non-combustible cigarette 100; please refer to [link / reference]. Figure 1 , Figure 3 , Figure 5 and Figure 7 It includes: a sealing section 10, a core section 20, a cooling support section 30, a filter section 40 arranged sequentially from upstream to downstream along the aerosol suction direction, as well as a first wrapping layer 50 and a second wrapping layer 60. The core section 20 includes a fragrance-carrying section 24 and a smoke-generating section 22. The fragrance-carrying section 24 includes a fusible solid carrier and fragrance attached to the fusible solid carrier. The first wrapping layer 50 wraps at least the filter section 40, and the second wrapping layer 60 wraps at least the sealing section 10. The first wrapping layer 50 and the second wrapping layer 60 are joined together.

[0056] The sealing section 10 is cylindrical to facilitate assembly, and its length is not less than 2.5mm to facilitate processing. For example, the length range can be 2.5mm to 5mm. In the actual manufacturing process, the length of the sealing section 10 can be selected as 2.5mm, 3mm, 4mm, 5mm, etc. as needed.

[0057] The upstream end in the aerosol suction direction is the distal nozzle end, and the downstream end in the aerosol suction direction is the proximal nozzle end. The filtration section 40 is used to filter the aerosol gas and further cool or filter and adsorb harmful substances. The filtration section 40 and the sealing section 10 can be, for example, one or more of the following: cellulose acetate rods, polypropylene rods, polylactic acid rods, and paper filter rods. For example, they can be composed of multiple filter rods, a single-material filter rod, or a composite filter rod of at least two materials.

[0058] The cooling support section 30 is used to maintain the structure of the heated non-combustible cigarette 100, and even adsorb and filter the aerosol gas generated by the heated non-combustible cigarette 100, and cool the aerosol gas so that the aerosol gas meets the inhalation requirements. The cooling support section 30 can be a hollow tube or other tubular fastener with a central opening or grooves around the perimeter. When the aroma-carrying section 24 is located close to the cooling support section 30, the cooling support section 30 can be a columnar part with multiple holes in the center, or it can be made of pleated thin sheets gathered or wound into a rod, with the gaps inside the rod forming an aerosol cooling channel. In this case, the cooling support section 30 is not a hollow tube to prevent the aroma-carrying section 24 from melting and flowing out into the filter section 40.

[0059] The order in which the smoke-generating section 22 and the incense-carrying section 24 are set is not limited. The smoke-generating section 22 can be set upstream of the incense-carrying section 24 or downstream of the incense-carrying section 24, such as... Figure 1 and Figure 2 As shown, Figure 3and Figure 4 As shown, Figure 5 and Figure 6 As shown, Figure 7 and Figure 8 As shown. The smoke-generating section 22 and the fragrance-carrying section 24 can be fitted together, or a separate piece of firmware can be placed between the smoke-generating section 22 and the fragrance-carrying section 24.

[0060] The smoke-generating section 22 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, sheets, or solid columnar forms. In particular, the core material of this application can be solid columnar, filamentous, or sheet-like, which is beneficial for the production of the twisting process.

[0061] The fragrance carrier segment 24 includes a fusible solid carrier and a fragrance adhering 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 both molten and solid states; it is solid at room temperature and becomes a molten liquid after heating.

[0062] Therefore, in the heated tobacco product 100 of this application, the aroma-carrying segment 24 is solid at room temperature, and the aroma is "locked" in the solid medium. This can avoid the phenomenon of aroma contaminating the tube wall during the storage of the heated tobacco product 100. Furthermore, the aroma is not added to the core material, so it does not increase the weight of the smoke-generating segment 22 and reduces costs. When the heated tobacco product 100 is heated and used, the aroma-carrying segment 24 is a molten liquid, thereby releasing the aroma.

[0063] The first wrapping layer 50 and the second wrapping layer 60 can be, for example, packaging paper, which can be a porous or non-porous packaging material. The first wrapping layer 50 can wrap only the filter section 40, or wrap the filter section 40 and the cooling support section 30, or wrap the filter section 40, the cooling support section 30, and the core section 20. The second wrapping layer 60 can wrap only the sealing section 10, or wrap the sealing section 10 and the core section 20, or it can wrap the sealing section 10, the core section 20, and the cooling support section 30.

[0064] The heating non-combustible cigarette 100 provided in this application includes a core section 20 comprising a smoke-generating section 22 and a flavor-carrying section 24. The flavor-carrying section 24 comprises a fusible solid carrier and a flavoring agent. 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 flavoring agent is "locked" in the solid medium, making the flavor-carrying section 24 and the smoke-generating section 22 independent sections. This can avoid the phenomenon of flavoring agent contaminating the tube wall during the storage of the heating non-combustible cigarette 100. Furthermore, since the flavor-carrying section 24 is isolated from the smoke-generating section 22, the weight of the smoke-generating section 22 can be reduced, thereby reducing costs.

[0065] In addition, the fragrance-carrying section 24 is isolated from the smoke-generating section 22, which allows the smoke-generating section 22 to remain as dry as possible and free from moisture. The fragrance-carrying section 24 can also absorb more fragrance without increasing the weight of the smoke-generating section 22, making the aroma more intense during inhalation. The fragrance-carrying section 24 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 24 is not easily volatile, which can lock in the aroma for a longer time. Furthermore, after the fragrance-carrying section 24 melts, the fragrance begins to evaporate when heated, and the fragrance-carrying section 24 will shift to a certain position. The space occupied by the fragrance-carrying section 24 can act as a cooling channel, which indirectly extends the cooling section and improves the cooling effect.

[0066] The aroma-carrying segment 24 has a length of 5-13 mm in the longitudinal direction of the heated non-combustible cigarette 100. For example, it can be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 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. The mass of the aroma-carrying segment 24 is about 100 mg, for example, 80 mg-120 mg.

[0067] In some embodiments, the ratio of the length of the fragrance-carrying section 24 to the length of the smoke-generating section 22 is 0.4 to 0.8, for example, 0.4, 0.5, 0.6, 0.7, or 0.8. The total length of the fragrance-carrying section 24 and the smoke-generating section 22 is not greater than 25 mm.

[0068] Within the aforementioned range, the ratio of the length of the aroma-carrying section 24 to the length of the smoke-generating section 22 ensures that the aroma concentration and draw resistance of the heated non-combustible cigarette 100 are appropriate, and also helps control costs. If the ratio of the length of the aroma-carrying section 24 to the length of the smoke-generating section 22 is too high, the weight cannot be guaranteed, resulting in a distortion of the aroma of the smoke-generating section itself, an unnatural aerosol aroma, and increased draw resistance; if the length of the aroma-carrying section 24 to the length of the smoke-generating section 22 is too low, the weight is too high, and the cost is too high.

[0069] 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 and allowed to solidify naturally to obtain fragrance segment 24. The fragrance includes aroma-producing substances, such as various fruity and minty flavorings.

[0070] In some embodiments, 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.

[0071] In some embodiments, please refer to Figure 1 and Figure 2 The first wrapping layer 50 wraps the core section 20, the cooling support section 30, and the filter section 40; the second wrapping layer 60 wraps the sealing section 10 and the first wrapping layer 50.

[0072] In some embodiments, please refer to Figure 3 and Figure 4 The second wrapping layer 60 wraps the sealing section 10, the smoke core section 20, and the cooling support section 30. The first wrapping layer 50 wraps the filter section 40 and the second wrapping layer 60.

[0073] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 The heated tobacco product 100 also includes a third wrapping layer 70, a first wrapping layer 50 wrapping a filter section 40, a second wrapping layer 60 wrapping a sealing section 10, and a third wrapping layer 70 wrapping both the first and second wrapping layers 50, as well as at least one segment of the aroma-carrying section 24, the smoke-generating section 22, and the cooling support section 30. That is, the heated tobacco product 100 comprises two segments, each independently constructed from the first and second wrapping layers 50 and 60, which are then combined by the third wrapping layer 70 to form the complete heated tobacco product 100. For example, the process of combining these two segments by the third wrapping layer 70 can be achieved through a stitching process.
