Description

Technical Field

[0001] The present application relates to the field of new tobacco technology, and particularly to a heat-not-burn cigarette and an aerosol generating system. Background Art

[0002] Heat-not-burn cigarette products are a type of new cigarette products developed in recent years. Since an external heat source is used to heat and bake to release smoke, the release amount of harmful components of the products is significantly reduced. Compared with traditional combustible tobacco, the safety of the products has been significantly improved and is recognized by the market.

[0003] In related heat-not-burn cigarette products, flavors are usually added to the tobacco section, and the weight of the flavors will cause an increase in the mass of the tobacco section. This results in that in some regions, the flavors are also misclassified as part of the tobacco material and taxed, causing higher costs, and there is a phenomenon that the tobacco section adsorbed with a sufficient amount of flavors pollutes the inner wall of the heat-not-burn cigarette product.

[0004] To address this problem, it can be solved by adding greaseproof paper or applying a greaseproof layer to the inner wall of the paper tube and reducing the usage amount of flavors. However, adding greaseproof paper or applying a greaseproof layer to the inner wall of the paper tube can slow down the leakage of flavors and smoking materials for a certain period of time, but this slowdown effect often lasts for a short time; in addition, reducing the usage amount of flavors will cause a decrease in the aroma concentration of the heat-not-burn cigarette product and affect the usage experience. Summary of the Utility Model

[0005] The purpose of the present application is to provide a heat-not-burn cigarette and an aerosol generating system, aiming to solve the problems of high cost and wall pollution of existing heat-not-burn cigarettes.

[0006] To achieve the above purpose, the present application provides a heat-not-burn cigarette, including: a plugging section, a tobacco core section, a cooling and supporting section, a filtering section, which are arranged in sequence from upstream to downstream along the aerosol suction direction, and a first wrapping layer and a second wrapping layer. The tobacco core section includes a flavor-carrying section and a smoking section; the flavor-carrying section includes a fusible solid carrier and a flavor attached to the fusible solid carrier; the first wrapping layer at least wraps the filtering section, the second wrapping layer at least wraps the plugging section, and the first wrapping layer and the second wrapping layer are joined to each other.

[0007] In some embodiments, the flavor-carrying section is arranged upstream or downstream of the smoking section.

[0008] In some embodiments, the fusible solid carrier includes polyethylene glycol or carnauba wax; the fusible solid carrier is in a liquid state at a temperature of 60°C or above.

[0009] In some embodiments, the tobacco core material of the smoking section is filamentous, sheet-like or solid columnar.

[0010] In some embodiments, the ratio of the length of the fragrance-carrying segment to the length of the smoke-emitting segment is 0.4 to 0.8.

[0011] In some embodiments, the length of the fragrance-carrying segment is 5-13 mm.

[0012] In some embodiments, the first wrapping layer wraps the cigarette core segment, the cooling support segment, and the filtering segment; the second wrapping layer wraps the blocking segment and the first wrapping layer.

[0013] In some embodiments, the second wrapping layer wraps the plugging section, the smoke core section, and the cooling support section, and the first wrapping layer wraps the filtering section and the second wrapping layer.

[0014] In some embodiments, a third wrapping layer is also included, wherein the first wrapping layer wraps the filtering segment, the second wrapping layer wraps the blocking segment, and the third wrapping layer wraps the first wrapping layer, the second wrapping layer, and at least one segment of the fragrance carrying segment, the smoke generating segment, and the cooling support segment.

[0015] The present application also provides an aerosol generating system, comprising the above-mentioned heat-not-burn cigarette and a heating device adapted for the heat-not-burn cigarette.

[0016] Compared with the related art, the beneficial effects of this application include:

[0017] The tobacco core segment of the heat-not-burn cigarette provided in the present application includes a flavor-carrying segment and a smoke-generating segment. The flavor-carrying segment includes a fusible solid carrier and a flavoring agent 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 flavoring agent is "locked" in the solid medium, so that the flavor-carrying segment and the smoke-generating segment are two independent segments, which can avoid the phenomenon of flavoring agent contaminating the tube wall during the storage of the heat-not-burn cigarette, and because the flavor-carrying segment is isolated from the smoke-generating segment, the weight of the smoke-generating segment can be reduced to reduce costs.

[0018] In addition, the fragrance-carrying section is isolated from the smoke-generating section, so that the smoke-generating section can be kept as dry as possible and free from moisture; the heat-not-burn cigarettes can also absorb more fragrances without increasing the weight of the smoke-generating section, making the fragrance richer during the smoking process; the heat-not-burn cigarettes can release the fragrance more evenly, so that the fragrance is not released quickly at the beginning of heating; the fragrances in the heat-not-burn cigarettes are not easy to volatilize, and can lock the fragrance for a longer time; and after the fragrance-carrying section is melted, the fragrance begins to heat and volatilize, and the fragrance-carrying section will migrate to a certain position. The space occupied by the fragrance-carrying section can be used as a cooling channel, which in disguised form extends the cooling section and improves the cooling effect.

[0019] The aerosol generated by the aerosol generating system provided in the present application has a strong aroma and a good cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] As used herein, the terms:

[0037] "Prepared from" is synonymous with "comprising". The terms "comprising", "including", "having", "containing" or any other variation thereof as used herein are intended to cover non - exclusive inclusion. For example, a composition, step, method, article or apparatus that comprises 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 connective "consisting of" excludes any unstated element, step or component. If used in a claim, this phrase will render the claim closed, excluding materials other than those described, except for conventional impurities associated therewith. When the phrase "consisting of" appears in a clause within the body of a claim rather than immediately following the subject, it only limits the elements described in that clause; other elements are not excluded from the claim as a whole.

[0039] When an equivalent, concentration, or other value or parameter is expressed as a range, a preferred range, or a range defined by a series of upper preferred values and lower preferred values, this should be understood to specifically disclose all ranges formed by any pairing of any range upper limit or preferred value with any range lower limit or preferred value, whether or not the ranges are separately disclosed. For example, when the range "1 - 5" is disclosed, the described range should be interpreted to include the ranges "1 - 4", "1 - 3", "1 - 2", "1 - 2 and 4 - 5", "1 - 3 and 5", etc. When a numerical range is described herein, unless otherwise stated, the range is intended to include its end values and all integers and fractions within the range.

[0040] "And / or" is used to indicate that either or both of the stated circumstances may occur, e.g., A and / or B includes (A and B) and (A or B).

[0041] This application provides a heat - not - burn cigarette 100. Please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 7, including: a plugging section 10, a tobacco core section 20, a cooling and supporting section 30, a filtering section 40 arranged in sequence from upstream to downstream along the aerosol suction direction, as well as a first wrapping layer 50 and a second wrapping layer 60. The tobacco core section 20 includes a flavor-carrying section 24 and a fuming section 22; the flavor-carrying section 24 includes a fusible solid carrier and a flavor attached to the fusible solid carrier; the first wrapping layer 50 at least wraps the filtering section 40, the second wrapping layer 60 at least wraps the plugging section 10, and the first wrapping layer 50 and the second wrapping layer 60 are joined to each other.

[0042] Among them, the plugging section 10 is columnar for convenient combination, and its length is not less than 2.5 mm, which is convenient for processing. For example, the length range can be 2.5 mm to 5 mm. In the actual manufacturing process, the length of the plugging section 10 can be selected as 2.5 mm, 3 mm, 4 mm, 5 mm, etc. according to needs.

[0043] Among them, the upstream of the aerosol suction direction is the far mouth end, and the downstream of the aerosol suction direction is the near mouth end. The filtering section 40 is used to filter the aerosol gas and further cool it or filter and adsorb harmful substances. The filtering section 40 and the plugging section 10 can be, for example, one or more of a cellulose acetate filter rod, a polypropylene filter rod (polypropylene fiber rod), a polylactic acid filter rod, and a paper filter rod. For example, it can be composed of splicing multiple filter rods, or a filter rod of a single material, or a composite filter rod of at least two materials.

[0044] The cooling and supporting section 30 is used to maintain the structure of the heat-not-burn cigarette 100, and even adsorb and filter the aerosol gas generated by the heat-not-burn cigarette 100, and cool the aerosol gas so that the aerosol gas meets the suction requirements. The cooling and supporting section 30 can be an empty tube or other tubular fasteners with holes in the middle or grooves on the periphery. Among them, when the flavor-carrying section 24 is arranged close to the cooling and supporting section 30, the cooling and supporting section 30 can be a columnar member with multiple holes in the center, or a rod formed by gathering or winding a thin sheet with folds, and the gap inside the rod forms an aerosol cooling channel. At this time, the cooling and supporting section 30 is not a hollow tube to prevent the molten flavor-carrying section 24 from flowing out to the filtering section 40.

[0045] The setting order of the fuming section 22 and the flavor-carrying section 24 is not limited. The fuming section 22 can be arranged upstream of the flavor-carrying section 24 or downstream of the flavor-carrying section 24, as Figure 1 and Figure 2 shown, Figure 3 and Figure 4 shown, Figure 5 and Figure 6 shown, Figure 7 and Figure 8 shown. The fuming section 22 and the flavor-carrying section 24 can be arranged in a fitting manner, or a fastener can also be arranged between the fuming section 22 and the flavor-carrying section 24.

[0046] The smoking section 22 is the core material of the cigarette, which can be, for example, tobacco raw materials, herbal medicines, or fiber paper substrates adsorbed with smoking agents. The form of the core material can be granular, slurry-like, filamentous, flaky, solid columnar, etc. The core material of the present application can particularly be solid columnar, filamentous, and flaky, which is beneficial to the production of the tipping process.

[0047] The flavor-carrying section 24 includes a fusible solid carrier and a flavor attached to the fusible solid carrier. The flavor can be a solid flavor or a liquid flavor. The liquid flavor is adsorbed on the fusible solid carrier, and the solid flavor is wrapped in the fusible solid carrier. A smoking agent can also be mixed in the fusible solid carrier. The smoking agent is, for example, selected from propylene glycol, glycerol, triacetin, or diacetin, etc. The fusible solid carrier has a molten state and a solid state, is solid at normal temperature, and is a molten liquid after heating.

[0048] Therefore, for the heat-not-burn cigarette 100 of the present application, at normal temperature, the flavor-carrying section 24 is solid, and the flavor is "locked" in the solid medium, which can avoid the phenomenon of flavor contaminating the tube wall during the storage of the heat-not-burn cigarette 100. And the flavor is not added to the core material, which will not increase the weight of the smoking section 22 and reduces the cost; when the heat-not-burn cigarette 100 is used under heating, the flavor-carrying section 24 is a molten liquid, thereby releasing the flavor.

[0049] Among them, the first wrapping layer 50 and the second wrapping layer 60 can be, for example, wrapping papers, and the wrapping papers can be porous wrapping materials or non-porous wrapping materials. The first wrapping layer 50 can only wrap 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 only wrap the plugging section 10, or wrap the plugging section 10 and the core section 20, and can also wrap the plugging section 10, the core section 20, and the cooling support section 30.

[0050] The core section 20 of the heat-not-burn cigarette 100 provided by the present application includes a smoking section 22 and a flavor-carrying section 24. The flavor-carrying section 24 includes a fusible solid carrier and a flavor. The fusible solid carrier has a molten state and a solid state, is solid at normal temperature, and is in a molten state after heating. At normal temperature, the flavor is "locked" in the solid medium, making the flavor-carrying section 24 and the smoking section 22 two independent sections, which can avoid the phenomenon of flavor contaminating the tube wall during the storage of the heat-not-burn cigarette 100. And since the flavor-carrying section 24 is isolated from the smoking section 22, the gram weight of the smoking section 22 can be reduced to reduce the cost.

[0051] In addition, the fragrance carrying segment 24 is isolated from the smoke generating segment 22, so that the smoke generating segment 22 can be kept as dry as possible and free from moisture; the fragrance carrying segment 24 can also absorb more fragrances without increasing the weight of the smoke generating segment 22, thereby making the fragrance during the smoking process more intense; the fragrance carrying segment 24 can release the fragrance more evenly, so that the fragrance is not released quickly at the beginning of heating; the fragrance in the fragrance carrying segment 24 is not easy to volatilize, and can lock the fragrance for a longer time; and after the fragrance carrying segment 24 is melted, the fragrance begins to heat and volatilize, and the fragrance carrying segment 24 will migrate to a certain position, and the space occupied by the fragrance carrying segment 24 can be used as a cooling channel, which in disguise extends the cooling section and improves the cooling effect.

[0052] Among them, the size (i.e., length) of the aroma segment 24 in the length direction of the heat-not-burn cigarette 100 is 5-13 mm, 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, and the mass of the obtained aroma segment 24 is about 100 mg, for example, 80 mg-120 mg.

[0053] In some embodiments, the ratio of the length of the fragrance carrying segment 24 to the length of the smoke generating segment 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 segment 24 and the smoke generating segment 22 is not greater than 25 mm.

[0054] The ratio of the length of the aroma-carrying segment 24 to the smoke-generating segment 22 within the above range can ensure that the aroma concentration and the draw resistance of the heat-not-burn cigarette 100 are appropriate, and is also conducive to controlling costs. If the ratio of the length of the aroma-carrying segment 24 to the smoke-generating segment 22 is too high, the gram weight cannot be guaranteed, resulting in the distortion of the aroma of the smoke-generating segment itself, the unnatural aroma of the aerosol, and the increase of the draw resistance; if the ratio of the length of the aroma-carrying segment 24 to the smoke-generating segment 22 is too low, the gram weight is too large and the cost is too high.

[0055] In some embodiments, the fusible solid carrier is solid at room temperature and liquid at a temperature of 60°C or above. The fusible solid carrier includes one or more of polyethylene glycol and carnauba wax. Both polyethylene glycol and carnauba wax are phase-change materials, solid at room temperature and liquid in a molten state after heating. The fusible solid carrier is uniformly mixed with the fragrance in a molten state and naturally solidified to obtain the fragrance carrier segment 24. The fragrance includes fragrance-causing substances, such as various fruity and mint-style characteristic fragrances.

[0056] 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.

[0057] In some embodiments, referring to Figure 1 and Figure 2 , the first wrapping layer 50 wraps the tobacco core segment 20, the cooling and supporting segment 30, and the filtering segment 40; the second wrapping layer 60 wraps the plugging segment 10 and the first wrapping layer 50.

[0058] In some embodiments, referring to Figure 3 and Figure 4 , the second wrapping layer 60 wraps the plugging segment 10, the tobacco core segment 20, and the cooling and supporting segment 30, and the first wrapping layer 50 wraps the filtering segment 40 and the second wrapping layer 60.

[0059] In some embodiments, referring to Figure 5 , Figure 6 , Figure 7 , Figure 8 , the heat-not-burn cigarette 100 further includes a third wrapping layer 70. The first wrapping layer 50 wraps the filtering segment 40, the second wrapping layer 60 wraps the plugging segment 10, and the third wrapping layer 70 wraps the first wrapping layer 50, the second wrapping layer 60, and at least one of the flavor-carrying segment 24, the smoke-generating segment 22, and the cooling and supporting segment 30. That is, the heat-not-burn cigarette 100 includes two segments respectively formed by the first wrapping layer 50 and the second wrapping layer 60 as independent structures, and the combined structure of these two segments is combined into the complete heat-not-burn cigarette 100 through the third wrapping layer 70. Exemplarily, the process of combining these two segments by the third wrapping layer 70 can be achieved through a rubbing and joining process.

[0060] As Figure 5 shown in the embodiment, the first wrapping layer 50 wraps the filtering segment 40, the cooling and supporting segment 30, and the flavor-carrying segment 24, the second wrapping layer 60 wraps the plugging segment 10 and the smoke-generating segment 22, and then the third wrapping layer 70 wraps the first wrapping layer 50 and the second wrapping layer 60.
