Description

[0003] Aerosol-generating products can generate aerosols through combustion. Specifically, the matrix section of the aerosol-generating product can be ignited, and aerosols are released during the combustion of the matrix section.

[0004] In related technologies, traditional tobacco shreds are used as the base segment to generate aerosols. The tobacco shred production process mainly involves selecting and sorting tobacco leaves from different origins and varieties after threshing and re-drying, removing impurities, and blending them according to formula requirements. Then, the moisture and temperature of the tobacco leaves are increased through methods such as steaming or spraying water to soften them for subsequent processing. The processed leaves are then cut into shreds that meet the process requirements, and the tobacco stems are also cut into stem shreds. Finally, the tobacco shreds are wrapped in cigarette paper using a cigarette rolling machine to create an aerosol-generated product. However, this type of aerosol-generated product suffers from insufficient aerosol release during inhalation. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0029] In the embodiments of this application, "first direction" refers to the direction shown in the accompanying drawings. It should be understood that these directional terms are only for the convenience of describing this application 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 application. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In this application, "multiple" includes two or more.

[0031] In related technologies, natural tobacco leaves or stems are directly used and processed, such as roasting and then shredded. The true density of this traditional tobacco shreds formed by roasting and shredding is relatively low, resulting in insufficient aerosol release.

[0032] Please see Figures 1 to 3 This application provides an aerosol generating article, including a functional segment 1 and a matrix segment 2. The matrix segment 2 is disposed at one end of the functional segment 1 along a first direction. The matrix segment 2 includes a plurality of first matrices, each of which includes a homogeneous tobacco structure. The matrix segment 2 is used to be ignited to generate aerosol.

[0033] The term "matrix segment 2 is used to be ignited to generate aerosol" means that matrix segment 2 is heated above the ignition point to generate aerosol during combustion.

[0034] Homogeneous tobacco structure is reconstituted tobacco formed by recombining natural tobacco raw materials. For example, reconstituted tobacco with approximately uniform quality is produced by physically recombining natural tobacco raw materials such as tobacco leaves, tobacco stems and tobacco dust with liquid raw materials.

[0035] In some embodiments, the matrix segment 2 includes one of a sheet matrix, a strip matrix, and a granular matrix. Exemplarily, a single first matrix may be a sheet matrix, a strip matrix, or a granular matrix.

[0036] In other words, a single matrix segment 2 may include one of a sheet matrix, a strip matrix, and a granular matrix. A single matrix segment 2 may also include two or three of the sheet matrix, strip matrix, and granular matrix. For example, a portion of the first matrix is ​​a sheet matrix, and another portion of the first matrix is ​​a strip matrix 21.

[0037] A sheet matrix refers to a matrix 11 whose thickness dimension is smaller than the hydraulic diameter of the first cross-sectional shape, where the first cross-sectional shape is perpendicular to the thickness direction of the strip matrix 21.

[0038] The term "strip matrix" refers to the extruded matrix 11 having a length dimension greater than the hydraulic diameter of the first cross-sectional shape. For example, the length of the strip-shaped extruded matrix 11 is not limited; it can be a long strip or a relatively short strip. Here, the first cross-sectional shape is perpendicular to the length direction of the strip matrix 21.

[0039] The granular matrix is ​​spherical or near-spherical. For example, the particle size of individual particles in the granular matrix is ​​on the order of millimeters or larger.

[0040] The hydraulic diameter is the ratio of four times the area of ​​the first cross-sectional shape to the perimeter of the first cross-sectional shape.

[0041] In some embodiments, the first substrate is a strip-shaped substrate 21.

[0042] For example, natural tobacco raw materials such as tobacco leaves, tobacco stems and tobacco dust can be crushed into solid particles, and the solid particles and liquid raw materials can be mixed and recombined to form an integrated structure, which can then be cut into strip-shaped matrix 21.

[0043] For example, one end of the aerosol generating article 100 faces the user along a first direction. For ease of description, the two ends of the first direction are defined as the proximal lip end and the distal lip end. The proximal lip end refers to the end of the aerosol generating article 100 that is closer to the user when the user is using the aerosol generating article 100, and the distal lip end refers to the end of the aerosol generating article 100 that is farther away from the user when the user is using the aerosol generating article 100.

[0044] For example, at least one functional segment 1 may be disposed near the lip end of the matrix segment 2, so that during use of the aerosol generating article 100, the aerosol generated by the matrix segment 2 flows through the functional segment 1 and is delivered to the user under suction negative pressure. That is, the functional segment 1 is downstream of the matrix segment 2 in the first direction, i.e., near the lip end. In some cases, the user can hold the functional segment 1 in their mouth to draw in the aerosol generated by the matrix segment 2.

[0045] In some embodiments, at least one functional segment 1 may be disposed at the distal lip end of the matrix segment 2. This provides the function of sealing the matrix segment 2 and reduces the risk of the strip matrix 21 detaching from the distal lip end.

[0046] Functional segment 1 can provide at least one of the following functions: filtration, adsorption, aroma enhancement, dilution, cooling, and resistance adjustment.

[0047] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0048] Adsorption function refers to the ability to adsorb at least some impurities in aerosols. It can be understood that these impurities are substances that remove the active ingredients from the aerosol; the active ingredients are those that need to be provided to the user.

[0049] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0050] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0051] Cooling function refers to the function of reducing the temperature of aerosols.

[0052] The suction resistance adjustment function refers to the function of reducing or increasing suction resistance. In this way, the flow rate and distribution of aerosols can be controlled, and the suction resistance and aerosol uniformity can be optimized.

[0053] The true density of the first matrix is ​​greater than that of traditional tobacco in related technologies. Using the first matrix can reduce the filling rate of matrix segment 2, thereby improving the quality of matrix segment 2. As a result, matrix segment 2 can generate more aerosols.

[0054] True density refers to the actual mass of a unit volume of the first matrix in an absolutely dense state, that is, the density after removing all the micropores of the first matrix. In other words, the volume here does not include the volume of the micropores of the first matrix.

[0055] The aerosol generating product provided in this application embodiment includes a first matrix comprising a homogeneous tobacco structure. The homogeneous tobacco structure is a reconstituted tobacco with approximately uniform mass, made by physically recombining natural tobacco raw materials such as tobacco leaves, tobacco stems and tobacco dust with liquid raw materials. The true density of the first matrix is ​​greater than that of tobacco shreds in related technologies. The matrix segment 2 includes multiple first matrices, which can improve the filling rate and increase the amount of aerosol generated by the matrix segment 2. Users can inhale more aerosols, thus improving the user experience.

[0056] In some embodiments, the matrix segment 2 includes a second matrix, the true density of which may be less than that of the first matrix.

[0057] In some embodiments, the second matrix is ​​a natural tobacco structure. A natural tobacco structure is the structure of tobacco raw material that has not been reconstituted. Exemplarily, the tobacco raw material is made by primary processing such as curing followed by rolling, shredding, slicing, or pulverizing.

[0058] In related technologies, during the tobacco processing, the varying sizes of the tobacco leaves after threshing and re-drying result in inconsistent tobacco shred sizes during the shredding process, particularly in length. From a structural perspective, shreds longer than 3.35mm are generally classified as long shreds, those between 3.35mm and 2.5mm as medium shreds, those between 2.25mm and 1.0mm as short shreds, and those shorter than 1.0mm as broken shreds. To ensure uniform tobacco shreds within the aerosol product and to meet the required specifications for draw resistance, hardness, and roundness, a suitable ratio of long, medium, and short shreds is necessary. After shredding, the tobacco shreds are subjected to compression and friction during transport to the cigarette rolling machine, further increasing the number of broken shreds. To ensure the quality of aerosol-generated products, the tobacco shreds are typically sieved using vibrating sorting screens before entering the cigarette rolling machine to remove broken shreds. These broken shreds cannot be used in the leaf assembly, resulting in waste; the broken shred rate is generally 5%-10%. Furthermore, although the vibrating sorting screens remove broken shreds, long, medium, and short shreds still remain in the tobacco shreds. These tobacco components of varying lengths are wrapped in cigarette paper by the rolling machine. The wrapped tobacco shreds are randomly distributed and disordered, causing large fluctuations in the draw resistance of the aerosol-generated product, thus affecting the smoking experience.

[0059] Please see Figure 4 Multiple strip-shaped substrates 21 can be arranged in an orderly manner. This allows for adjustment of the suction resistance by changing the arrangement of the strip-shaped substrates 21 as needed.

[0060] Ordered arrangement refers to arranging according to a set rule or sequence, where the position of each strip matrix 21 is predictable. Ordered arrangement of multiple strip matrix 21 means that multiple strip matrix 21 are arranged according to a set rule or sequence, and the position of each strip matrix 21 can be controlled. The arrangement method and position of the strip matrix 21 are determined according to the design, and the strip matrix 21 is placed in the preset position according to the design.

[0061] For example, the multiple strip-shaped substrates 21 can be arranged in an orderly manner, such as a two-dimensional array, multiple concentric rings, or a spiral.

[0062] In some embodiments, please refer to Figure 5 Multiple strip-shaped matrix 21 are randomly filled. Random filling is the opposite of ordered arrangement. Random arrangement means that it is randomly generated and difficult to predict. In other words, the positions of each strip-shaped matrix 21 are random and have no pattern.

[0063] In some embodiments, the length direction of the strip matrix 21 is parallel to the first direction, and the length of each strip matrix 21 of a single matrix segment 2 is equal.

[0064] Each strip matrix 21 in a single matrix segment 2 has the same length. In this way, the multiple strip matrices 21 are arranged in an orderly manner, which also facilitates the flow of aerosols in the gaps of each strip matrix 21 along the first direction and reduces suction resistance fluctuations.

[0065] It is understandable that the length of each strip matrix 21 is equal, which may include manufacturing errors. For example, if the lengths of two strip matrixes 21 are within the range of manufacturing errors, they are also considered to be equal.

[0066] In this embodiment, the length direction of the strip matrix 21 is parallel to the first direction, and the extension direction of the multiple strip matrix 21 is the same. Thus, the multiple strip matrix 21 are arranged in an orderly manner, and the strip matrix 21 is roughly parallel to each other in a bundle structure. The length of each strip matrix 21 in a single matrix segment 2 is equal, and the spacing between two adjacent strip matrix 21 remains basically unchanged along the first direction. This is beneficial for the aerosol to flow along the first direction in the gaps of each strip matrix 21, which can reduce the suction resistance fluctuation during the suction process, improve the suction taste, and improve the user experience.

[0067] In some embodiments, please refer to Figures 1 to 2 The aerosol generating article 100 includes an encapsulation layer 3, and the matrix segment 2 includes an outer encapsulation layer 22. The outer encapsulation layer 22 is wound to form a receiving space with openings at both ends along a first direction, and a plurality of first matrices are received in the receiving space. The encapsulation layer 3 encapsulates at least a portion of the functional segment 1 and at least a portion of the outer encapsulation layer 22.

[0068] For example, the wrapping layer 3 can wrap a portion of functional segment 1 and a portion of outer wrapping layer 22. The wrapping layer 3 can also wrap a portion of functional segment 1 and the entirety of outer wrapping layer 22. Alternatively, the wrapping layer 3 can wrap the entirety of functional segment 1 and a portion of outer wrapping layer 22. The wrapping layer 3 can also wrap the entirety of functional segment 1 and the entirety of outer wrapping layer 22.

[0069] Multiple first substrates are housed within the accommodating space, meaning that the outer cladding layer 22 encloses multiple first substrates to constrain the first substrates.

[0070] In some embodiments, the multiple strip-shaped substrates 21 may not be bonded together with adhesive materials, but rather the multiple strip-shaped substrates 21 are bound together by an outer sheath 22, and the strip-shaped substrates 21 are constrained by friction to prevent them from falling out of the accommodating space.

[0071] In this embodiment, the outer layer 22 is used to constrain the strip matrix 21, and the wrapping layer 3 connects the matrix segment 2 and the functional segment 1 into a whole.

[0072] The material of the wrapping layer 3 is not limited, but includes, but is not limited to, cigarette paper or other materials.

[0073] The material of the outer layer 22 is not limited, but includes, but is not limited to, cork paper or other materials.

[0074] The number of functional segments 1 can be one or more. In embodiments with multiple functional segments 1, the multiple functional segments 1 can be arranged sequentially along a first direction. In some embodiments, at least two functional segments 1 have the same function. In some embodiments, at least two functional segments have different functions. That is, functional segments 1 with different functions can be combined according to different needs such as filtration and flavor enhancement.

[0075] It is understood that in an embodiment with multiple functional segments 1, the wrapping layer 3 can wrap all functional segments 1 to achieve the connection of functional segments 1.

[0076] In some embodiments, please refer to Figure 2 The strip matrix 21 is a reconstructed homogeneous structure.

[0077] Reconstructing a homogeneous structure refers to forming a monolithic structure from granular substrates and then cutting it into filaments. Specifically, the granular substrates are first formed into a monolithic structure, and then the monolithic structure is cut into filaments.

[0078] A one-piece structure refers to a structure manufactured through a single processing or integral molding process.

[0079] The granular substrate is a component in the form of granules. The strip matrix 21 is a granular aggregate composed of the granular substrate.

[0080] The granular substrate may include granular plant materials. The strip matrix 21 may also include an adhesive component for bonding the granular substrate. The adhesive component bonds the granular substrate together to form the main structure of the strip matrix 21.

[0081] In some embodiments, the particulate substrate may be formed from plant-based raw materials through granulation. Plant-based raw materials include, but are not limited to, one or more of tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants. Plant-based raw materials are the core source of aroma, and the endogenous substances in plant-based raw materials can produce physiological satisfaction for users. Endogenous substances, such as alkaloids, enter the human bloodstream and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0082] In this embodiment, the granular substrate is first formed into a single structure, and then the single structure is cut into filaments. Plant materials such as tobacco leaves and stems are reconstituted into homogeneous strip-shaped matrix 21. The distribution density of the granular substrate in each strip-shaped matrix 21 is more uniform, resulting in better suction consistency. Cutting the single structure into filaments can improve the dimensional consistency of each strip-shaped matrix 21 and provide better controllability.

[0083] The strip-shaped matrix 21 is a particle aggregate composed of a particulate substrate. The particles in the aggregate have micropores, at least some of which are interconnected to form microchannels. For example, the cross-sectional area and length of the microchannels are naturally formed by the material components, and expansion of the material components can also form microchannels. Aerosols can flow through these microchannels.

[0084] It should be noted that the microchannels described in this application are disordered, meaning they are difficult to generate in an orderly manner according to a design; in other words, the microchannels are generated randomly. Microchannels are all pores in a microscopic sense, and the distance between the two strip-shaped substrates 21 is much larger than the microchannel itself. The size of the microchannel is determined by the gap between particles. For example, if the material is granular, the strip-shaped substrate 21 formed by extrusion has microchannels. The cross-sectional area and length of the microchannel are naturally formed through the extrusion process and the material composition. The expansion of the material after it flows out of the die can form microchannels.

[0085] It is understandable that the particle size of the granular matrix is ​​formed by the combination of multiple granular substrates, and the particle size of the granular matrix is ​​larger than that of the granular substrate.

[0086] In some embodiments, the strip matrix 21 is a granular substrate that is formed into an integral structure by extrusion or roll forming, and then cut into shape.

[0087] Extrusion is a processing method in which materials are fed into an extruder, and the materials are pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passed through the die head to form products or semi-finished products with various cross-sections.

[0088] Roll forming is a processing method that applies pressure to materials using rollers to achieve specific processing effects. The core principle of roll forming is to continuously press or shape materials using two or more relatively rotating rollers.

[0089] For example, after pulverizing plant raw materials such as tobacco leaves and stems to form granular substrates, the granular substrates can be mixed with flavorings and fragrances, and then the mixed materials can be extruded or rolled to form continuous sheets or filaments or other integrated structures.

[0090] If the filament is continuous, it can be directly wrapped by the outer sheath 22 and then cut to the required length to form the matrix segment 2. Alternatively, the continuous strip can be cut to the required length to form a strip matrix 21, and then wrapped by the outer sheath 22 to form the matrix segment 2.

[0091] If the sheet is continuous, it is cut into continuous strips of the required width by a slitting device, then wrapped with the outer sheath 22, and cut to the required length to form the matrix segment 2. Alternatively, the continuous strips can be cut into strip-shaped matrix 21 first, and then wrapped with the outer sheath 22 to form the matrix segment 2.

[0092] It is understandable that fragrances are used to release aromatic substances after combustion. Adding fragrances to the particulate matrix allows matrix segment 2 to release a more distinctive aroma.

[0093] In some embodiments, no additional fragrance or flavoring may be added to the particulate substrate.

[0094] In this embodiment, the granular substrate is formed into an integral structure by extrusion or roll forming. The strip matrix 21 is less likely to detach locally before and after heating. Moreover, the process is simple, the molding effect is good, and it is also conducive to improving the yield.

[0095] In some embodiments, the width of the strip matrix 21 is 0.5 mm to 2.0 mm. Preferably, the width of the strip matrix 21 is 0.7 mm to 1.5 mm. More preferably, the width of the strip matrix 21 is 0.8 mm to 1.3 mm.

[0096] For example, the width of the strip matrix 21 is 0.5mm, 0.7mm, 0.8mm, 1.0mm, 1.2mm, 1.3mm, 1.5mm, 1.6mm, 1.8mm or 2.0mm, etc.

[0097] In this embodiment, when the width of the strip matrix 21 is less than 0.5 mm, the multiple strip matrix 21s are arranged more closely, and there are fewer gaps in the matrix segment 2, which increases the suction resistance. When the width of the strip matrix 21 is greater than 2 mm, the combustion of the strip matrix 21 is suppressed, affecting the combustion rate and thus affecting the suction experience. Therefore, the width of the strip matrix 21 is 0.5 mm to 2.0 mm, which can take into account both the requirements of suction resistance and combustion rate.

[0098] It is understandable that the length direction of the strip matrix 21 is the direction corresponding to the longest dimension of the strip matrix 21, the width direction of the strip matrix 21 intersects the length direction, and the dimension of the strip matrix 21 along the width direction is smaller than the dimension along the length direction.

[0099] In some embodiments, in a single matrix segment 2, the maximum width of the strip matrix 21 is W1, the minimum width of the strip matrix 21 is W2, and the ratio of W1 to W2 is 1.5-1.

[0100] Preferably, the ratio of W1 to W2 is 1.2-1.

[0101] More preferably, the ratio of W1 to W2 is 1, that is, the width of each strip matrix 21 is equal.

[0102] For example, the ratio of W1 to W2 can be 1.5, 1.2, 1.1 or 1, etc.

[0103] In this embodiment, the ratio of W1 to W2 is 1.5-1, the width of each strip matrix 21 is not much different, the material content of each strip matrix 21 is similar, the amount of aerosol released by each strip matrix 21 is relatively similar, and it is also beneficial to control the gaps between each strip matrix 21.

[0104] In some embodiments, the thickness of the strip matrix 21 is 0.05 mm to 0.5 mm.

[0105] Preferably, the thickness of the strip matrix 21 is 0.1 mm to 0.35 mm.

[0106] Preferably, the thickness of the strip matrix 21 is 0.15mm-0.25mm.

[0107] For example, the thickness of the strip matrix 21 is 0.05mm, 0.07mm, 0.08mm, 0.1mm, 0.12mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm or 0.5mm, etc.

[0108] It is understandable that the thickness direction, width direction and length direction of the strip matrix 21 intersect, and the dimension of the strip matrix 21 along the thickness direction is smaller than the dimension along the width direction.

[0109] In this embodiment, when the thickness of the strip matrix 21 is less than 0.05 mm, the strip matrix 21 is too thin, the structural strength is weak, and it is easy to be damaged; when the thickness of the strip matrix 21 is greater than 0.5 mm, the combustion of the strip matrix 21 is inhibited, affecting the combustion rate. Therefore, the thickness of the strip matrix 21 is 0.05 mm to 0.5 mm, which can take into account both the structural strength requirements and the combustion rate requirements.

[0110] In some embodiments, the number of strip-shaped substrates 21 in a single substrate segment 2 is not less than 30.

[0111] Preferably, in a single matrix segment 2, the number of strip-shaped matrix 21 is not less than 50.

[0112] More preferably, in a single matrix segment 2, the number of strip-shaped matrix 21 is not less than 70.

[0113] For example, in a single matrix segment 2, the number of strip matrix 21 can be 30, 40, 50, 60, 70, 80, 90 or 100, etc.

[0114] In this embodiment, the number of strip-shaped matrix 21 is too small, resulting in a small amount of aerosol released. In a single matrix segment 2, the number of strip-shaped matrix 21 is not less than 30, which is beneficial to meet the aerosol quantity requirements.

[0115] In some embodiments, the length of the aerosol-generating article 100 along the first direction is 60mm-120mm. This provides a suitable length for the aerosol-generating article 100, making it easy for the user to handle.

[0116] Preferably, the length of the aerosol-generated article 100 along the first direction is 70mm-110mm.

[0117] More preferably, the length of the aerosol-generating article 100 along the first direction is 80mm-100mm.

[0118] For example, the length of the aerosol generating article 100 along the first direction is 60mm, 70mm, 80mm, 90mm, 100mm, 110mm or 120mm, etc.

[0119] In some embodiments, the length of the matrix segment 2 is 30%-80% of the length of the aerosol-generated article 100.

[0120] Preferably, the length of the matrix segment 2 is 45%-75% of the length of the aerosol-generated article 100.

[0121] More preferably, the length of the matrix segment 2 is 60%-70% of the length of the aerosol-generated article 100.

[0122] For example, the length of the matrix segment 2 is a percentage of the length of the aerosol-generating article 100, such as 30%, 40%, 45%, 50%, 60%, 70%, 75%, or 80%, etc.

[0123] In this embodiment, the length of the matrix segment 2 is appropriate to meet the requirements of the amount of aerosol released, and the length of the functional segment 1 is appropriate. The aerosol released from the matrix segment 2 flows through the functional segment 1, which provides filtration and / or cooling for the aerosol, making the aerosol suitable for user use.

[0124] In some embodiments, the hydraulic diameter of the cross-sectional shape of the matrix segment 2 is 4mm-9mm, with a plane perpendicular to the first direction as the cross-section.

[0125] Preferably, the hydraulic diameter of the cross-sectional shape of the matrix segment 2 is 5mm-8.5mm.

[0126] More preferably, the hydraulic diameter of the cross-sectional shape of the matrix segment 2 is 5.3 mm to 8 mm.

[0127] For example, the hydraulic diameter of the substrate segment 2 is 4 mm, 4.5 mm, 5 mm, 5.3 mm, 5.5 mm, 6 mm, 7 mm, 8 mm, 8.5 mm or 9 mm, etc.
