[0001] This application relates to the field of aerosol generation technology, and more particularly to a matrix segment and an aerosol generation product. Background Technology

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] Aerosol-generating articles include a matrix segment, which can generate aerosols by ignition or by heating without combustion. In related technologies, the matrix segment only includes one type of aerosol-generating matrix, which is inconvenient for design and manufacturing. Utility Model Content

[0004] In view of this, embodiments of this application aim to provide a matrix segment and an aerosol generating article, including a first matrix and a second matrix, which facilitates design and manufacturing according to requirements.

[0005] The first aspect of this application provides a matrix segment, including:

[0006] The first substrate is an integral structure with a first cross section. The length of the first substrate is greater than the hydraulic diameter of the first cross section, and the first cross section is perpendicular to the length direction of the first substrate.

[0007] The second matrix, both the first matrix and the second matrix, are used to generate aerosols.

[0008] In some embodiments, the true density of the second matrix is ​​less than the true density of the first matrix.

[0009] In some embodiments, the second matrix includes at least one of a sheet matrix, a filamentary matrix, and a particulate matrix.

[0010] In some embodiments, the first matrix accounts for 1% to 99% of the total mass of the matrix segments.

[0011] In some embodiments, the fill rate of the matrix segment is 2 cm. 3 / g to 4cm 3 / g.

[0012] In some embodiments, the true density of the first matrix is ​​1 g / cm³. 3 Up to 1.5g / cm 3 .

[0013] In some embodiments, the tensile strength of the first matrix is ​​from 0.15 kN / m to 0.5 kN / m.

[0014] In some embodiments, the tensile index of the first matrix is ​​from 1 N·m / g to 2 N·m / g.

[0015] In some embodiments, the first cross-section is square, the length of the first cross-section is 0.8 mm to 1.1 mm, and the width of the first cross-section is 0.1 mm to 0.3 mm.

[0016] In some embodiments, the first matrix is ​​an extruded structure.

[0017] In some embodiments, the elongation at break of the first matrix is ​​1% to 6%.

[0018] In some embodiments, the mass of the first substrate per meter is 0.15g to 0.3g.

[0019] In some embodiments, the quantitative amount of the first matrix is ​​150 g / m³. 2 Up to 300g / m 2 .

[0020] In some embodiments, the burning rate of the first substrate is from 0.2 mm / s to 0.6 mm / s.

[0021] In some embodiments, a plurality of the first substrates are arranged in an ordered or disordered manner, and the second substrate fills the gaps between the plurality of the first substrates.

[0022] In some embodiments, the first matrix is ​​a homogeneous tobacco structure, and the second matrix is ​​a natural tobacco structure.

[0024] The matrix segment provided in this application has two advantages. First, the first matrix is ​​a one-piece structure, which has the advantage of being less prone to damage and breakage. Second, the matrix segment includes a first matrix and a second matrix, so the first matrix and the second matrix can be made into the matrix segment in different ways according to requirements, reducing the design and manufacturing difficulty.

[0040] Please see Figures 1 to 6 This application provides a matrix segment 1, including a first matrix 11 and a second matrix 12. The first matrix 11 is an integral structure with a first cross section. The length of the first matrix 11 is greater than the hydraulic diameter of the first cross section, and the first cross section is perpendicular to the length direction of the first matrix 11. Both the first matrix 11 and the second matrix 12 are used to generate aerosols.

[0041] The hydraulic diameter is the ratio of four times the area of ​​the first cross section to the perimeter of the first cross section.

[0042] The first matrix 11 and the second matrix 12 can be used to generate aerosols by ignition.

[0043] In some applications, the first matrix 11 and the second matrix 12 can also be used to generate aerosols through heating without combustion. That is, matrix segment 1 is heated below its ignition point to generate aerosols.

[0044] The first substrate 11 is an integral structure, meaning that the first substrate 11 is a single, indivisible physical whole that can maintain its overall state without the need for external components.

[0045] Please see Figure 1 The length of the first substrate 11 is greater than the hydraulic diameter of the first cross-section, which is perpendicular to the length direction of the first substrate 11. That is, the first substrate 11 is generally strip-shaped. Exemplarily, the length of the strip-shaped first substrate 11 is not limited; it can be a long strip or a relatively short strip. This facilitates the filling of the first substrate 11 and the second substrate 12. Exemplarily, for example, the second substrate 12 can be wrapped around the first substrate 11. Alternatively, the second substrate 12 can be sandwiched between two first substrates 11. Thus, the first substrate 11 and the second substrate 12 can be made into substrate segments 1 in different ways according to requirements, reducing design and manufacturing difficulty.

[0046] In addition, the first matrix 11 can also hold a high amount of fragrance and has a good retention rate, thereby improving the fragrance intensity and consistency of the aerosol inhaled by the user.

[0047] The matrix segment 1 provided in this application embodiment has two advantages. First, the first matrix 11 is a one-piece structure, which has the advantage of being less prone to damage and breakage. Second, the matrix segment 1 includes the first matrix 11 and the second matrix 12. Thus, the first matrix 11 and the second matrix 12 can be made into the matrix segment 1 in different ways according to requirements, reducing the design and manufacturing difficulty.

[0048] In some embodiments, the true density of the second matrix 12 is less than that of the first matrix 11. Thus, the first matrix 11 has a larger true density (typically 1 g / cm³). 3 Up to 1.5g / cm 3 This reduces the filling rate of matrix segment 1, thereby improving its quality. As a result, matrix segment 1 can generate more aerosols. Furthermore, by setting the first matrix 11, the thermal conductivity of matrix segment 1 can be increased (typically from 0.08 W / (m·K) to 0.15 W / (m·K)), thereby increasing the amount of visual smoke and aerosol capture mass (ACM) during user inhalation.

[0049] True density refers to the actual mass of a unit volume of the first matrix 11 in an absolutely dense state, that is, the density after removing all micropores. In other words, the volume here does not include the volume of the micropores of the first matrix 11.

[0050] In related technologies, the matrix segment uses only one of sheet matrix, filament matrix and granular matrix. The matrix segment 1 of this application embodiment includes a first matrix 11. For a single matrix segment, under the same size, the mass of the matrix segment 1 of this application can be increased by 10mg to 50mg compared with the mass of the matrix segment in related technologies.

[0051] Visual smoke volume refers to the amount of aerosol that a user can directly observe during inhalation. Fill rate refers to the volume occupied by a unit mass of matrix segment 1. In other words, the lower the fill rate of matrix segment 1, the greater its true density and mass. Conversely, the higher the fill rate of matrix segment 1, the lower its true density and mass.

[0052] It should be noted that if the filling rate of matrix segment 1 is too small, the suction resistance of matrix segment 1 will increase, affecting the user's aerosol suction. If the filling rate of matrix segment 1 is too large, the mass of matrix segment 1 will be too small, resulting in a reduction in the amount of aerosol and the user will not be able to suction more aerosols.

[0053] In this embodiment, the matrix segment 1 is prepared by blending the first matrix 11 and the second matrix 12, which can balance the filling rate and quality of the matrix segment 1, increase the amount of aerosol generated by the matrix segment 1, and allow users to draw more aerosols, thus improving the user experience.

[0054] In some embodiments, the first matrix 11 is a homogeneous tobacco structure, and the second matrix 11 is a natural tobacco structure.

[0055] Homogeneous tobacco structure is a reconstituted tobacco product made by physically recombining natural tobacco raw materials such as tobacco leaves, stems, and dust with liquid raw materials, resulting in a generally uniform quality. Thus, the product consistency of the first matrix 11 is relatively good.

[0056] Natural tobacco structure refers to tobacco leaves that have undergone primary processing, such as curing, before being rolled or shredded.

[0057] In some embodiments, the second matrix 12 includes at least one of sheet matrix, filament matrix and particulate matrix.

[0058] For example, the sheet matrix is ​​formed by processing natural plant materials such as leaves and tobacco stems into reconstituted sheets, and the processing methods include papermaking, slurry making, or roll forming.

[0059] Filamentous matrix is ​​made by cutting the original leaf and / or the above-mentioned thin film matrix into filaments.

[0060] The granular matrix is ​​formed by pulverizing the original leaf and / or the aforementioned flake matrix into dispersed particles. Exemplarily, the particle size of individual particles in the granular matrix is ​​on the millimeter scale. The second matrix 12 includes at least one of flake matrix, filamentous matrix, and granular matrix. The second matrix 12 may consist only of flake matrix; it may consist only of filamentous matrix; it may include granular matrix; or it may include two or three of flake matrix, filamentous matrix, and granular matrix.

[0061] In some embodiments, the first matrix 11 accounts for 1% to 99% of the total mass of matrix segment 1. The total mass of matrix segment 1 includes the mass of both the first matrix 11 and the second matrix 12. Exemplarily, the proportion of the first matrix 11 can be 1% to 99%, that is, the ratio of the mass of the first matrix 11 to the total mass of matrix segment 1 is 1% to 99%.

[0062] When the mass proportion of the first matrix 11 is within the aforementioned range, on the one hand, without significantly increasing the suction resistance of the matrix segment 1, users can inhale more aerosols, improving the user experience. On the other hand, it can also increase the thermal conductivity of the matrix segment 1, thereby increasing the amount of visual smoke and aerosol capture during the user's inhalation process.

[0063] For example, the proportion of the first matrix 11, based on the total mass of the matrix segment 1, can be any value among 1%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 99%, or a value between any two values.

[0064] In one embodiment, the proportion of the second matrix 12 can be from 1% to 99%, that is, the ratio of the mass of the second matrix 12 to the total mass of the matrix segment 1 is from 1% to 99%.

[0065] In some embodiments, the fill rate of matrix segment 1 is 2 cm. 3 / g to 4cm 3 / g.

[0066] The filling rate of matrix segment 1 is within the above range. Matrix segment 1 not only has a large mass to generate a sufficient number of aerosols for users to aspirate, but also prevents the suction resistance of matrix segment 1 from being too large and affecting users' aspiration.

[0067] For example, the filling rate of matrix segment 1 can be 2 cm. 3 / g, 2.2cm 3 / g, 2.4cm 3 / g, 2.6cm 3 / g, 2.8cm 3 / g, 3cm 3 / g, 3.2cm 3 / g, 3.4cm 3 / g, 3.6cm 3 / g, 3.8cm 3 / g、4cm 3 The value between any number in / g or any two numbers within a range.

[0068] In some embodiments, the combustion rate of the first substrate 11 is from 0.2 mm / s to 0.6 mm / s.

[0069] For the matrix segment 1 that generates aerosols by ignition, the combustion rate of the first matrix 11 is within the aforementioned range. On the one hand, this prevents the combustion rate from being too slow, which would result in high draw resistance in the matrix segment 1. On the other hand, it prevents the combustion rate from being too fast, which would shorten the user's inhalation time and cause the aerosol temperature to become too high, thereby producing irritating substances. In this way, the first matrix 11 can adopt an appropriate combustion rate according to needs to match the user's breathing rhythm, which is beneficial to the temperature and release amount of the aerosol and avoids the "burning mouth" problem.

[0070] For example, the combustion rate of the first substrate 11 can be any value among 0.2 mm / s, 0.3 mm / s, 0.4 mm / s, 0.5 mm / s and 0.6 mm / s or a range between any two values.

[0071] In some embodiments, the true density of the first matrix 11 is 1 g / cm³. 3 Up to 1.5g / cm 3 .

[0072] By ensuring the true density of the first matrix 11 is within the aforementioned range, on the one hand, excessive porosity of the first matrix 11 can be prevented, which would negatively impact its thermal conductivity during combustion. On the other hand, excessive additives in the first matrix 11 can be avoided, thus preserving its original flavor. In this way, the first matrix 11 can be configured with an appropriate true density as needed, ensuring not only its stability during combustion but also more accurately reflecting its original flavor and improving the user experience.

[0073] For example, the true density of the first matrix 11 may be 1 g / cm³. 3 1.1g / cm 3 1.2g / cm 3 1.3g / cm 3 1.4g / cm 3 and 1.5g / cm 3 The value between any one or any two values ​​in the range.

[0074] In some embodiments, the tensile strength of the first matrix 11 is between 0.15 kN / m and 0.5 kN / m. Tensile strength refers to the maximum stress that the first matrix 11 per unit size can withstand before tensile fracture.

[0075] By ensuring that the tensile strength of the first matrix 11 is within the aforementioned range, the stability of the first matrix 11 during the preparation and heating processes can be maintained. Specifically, on the one hand, the mechanical strength of the first matrix 11 can be improved, ensuring that the first matrix 11 will not experience breakage or other problems during processing, thereby increasing the yield of the first matrix 11. On the other hand, it can prevent the first matrix 11 from having excessive mechanical strength, which would lead to a lack of sufficient elasticity and make it difficult for the first matrix 11 to expand uniformly during combustion.

[0076] For example, the tensile strength of the first matrix 11 is any value or a range of any two values ​​among 0.15 kN / m, 0.2 kN / m, 0.25 kN / m, 0.3 kN / m, 0.35 kN / m, 0.4 kN / m, 0.45 kN / m and 0.5 kN / m.

[0077] In some embodiments, the tensile index of the first matrix 11 is from 1 N·m / g to 2 N·m / g. The tensile index is the ratio of tensile strength to basis weight, representing the tensile strength per unit basis weight (grams per square meter) of the first matrix 11. The tensile index is used to measure the tensile capacity of the first matrix 11.

[0078] By ensuring that the tensile index of the first matrix 11 is within the aforementioned range, it is beneficial to balance production costs and durability. Specifically, this improves the mass strength of the first matrix 11 and prevents damage during transportation and storage. Furthermore, it not only avoids altering the combustion characteristics of the first matrix 11 but also reduces costs.

[0079] For example, the tensile index of the first matrix 11 can be any value or a range of any two values ​​among 1 N·m / g, 1.1 N·m / g, 1.2 N·m / g, 1.3 N·m / g, 1.4 N·m / g, 1.5 N·m / g, 1.6 N·m / g, 1.7 N·m / g, 1.8 N·m / g, 1.9 N·m / g, and 2 N·m / g.

[0080] In this application, combustion characteristics refer to the combustion behavior of the first matrix 11 when ignited and its related parameters. For example, combustion characteristics include parameters such as flammability, heat release and smoke generation.

[0081] In some embodiments, the first cross-section is square, with a length of 0.8 mm to 1.1 mm and a width of 0.1 mm to 0.3 mm.

[0082] On the one hand, the length of the first cross-section is within the aforementioned range, which balances the combustion stability and processing feasibility of the first substrate 11. Specifically, the first substrate 11 has a suitable filling ratio, enabling smooth airflow within the substrate section 1, preventing uneven combustion (e.g., localized overheating or extinction) and improving combustion efficiency. Furthermore, it reduces the processing difficulty of the first substrate 11, lowers the probability of breakage, and reduces the ash generated during combustion, maintaining the consistency of the aerosol's taste.

[0083] On the other hand, the width of the first cross-section being within the aforementioned range maintains the mechanical strength of the first matrix 11 while promoting complete combustion of the first matrix 11 and optimizing the aerosol release rate. Specifically, it prevents the first matrix 11 from breaking and appropriately slows down the carbonization rate of the first matrix 11 during combustion, reducing the probability of generating harmful substances. Furthermore, it balances the amount of oxygen required for the combustion of the first matrix 11, preventing incomplete combustion (e.g., the generation of carbon monoxide) that could affect the taste of the aerosol.

[0084] For example, the length of the first cross section can be any value among 0.8mm, 0.85mm, 0.9mm, 0.95mm, 1mm, 1.05mm and 1.1mm or a value between any two values.

[0085] For example, the width of the first section can be any value among 0.1mm, 0.15mm, 0.2mm, 0.25mm and 0.3mm or a value between any two values.

[0086] In other embodiments, the first cross-section may also be at least one of circular, triangular, and irregular shapes. Exemplarily, the first cross-section may be circular; the first cross-section may also be triangular; the first cross-section may also be irregular; the first cross-sections of different first substrates 11 may also be two or three of circular, triangular, and irregular shapes respectively.

[0087] In related technologies, tobacco leaves and stems in papermaking, slurry processing, and roll pressing processes need to be processed separately, often resulting in low utilization rates and significant waste. Furthermore, these processing methods can only hold a small amount of flavoring, leading to low flavor loading in the matrix section. During the aerosol generation process by heating the matrix section, the flavoring aroma is not pronounced, affecting the consistency of the aerosol's taste.

[0088] In some embodiments, please refer to Figure 2 The first matrix 11 is an extrusion molding structure. Extrusion molding refers to a process in which materials are pushed by the screw through the barrel and screw of an extruder 20, continuously passing through the die head to form products or semi-finished products of various cross-sections. Compared with papermaking, slurry making, and roll forming, the molding process of the first matrix 11 is simpler and can make full use of plant raw materials, reducing material waste and lowering production costs. On the other hand, the first matrix 11 can hold more fragrance, and the fragrance in the first matrix 11 prepared by extrusion molding can achieve uniform distribution and good retention rate, further improving the aroma intensity and consistency of the aerosol inhaled by the user.

[0089] In some embodiments, the first matrix 11 has micropores inside, and multiple micropores are interconnected to form microchannels. This increases the porosity of the first matrix 11, thereby improving the aerosol release rate. For example, in the first matrix 11 of a particle aggregate, the gaps between the particles constitute micropores. Exemplarily, the mixture used to prepare the first matrix 11 is a granular material, and the first matrix 11 formed by extrusion of the mixture has micropores. The cross-sectional area and length of the micropores are naturally formed through the extrusion process and the raw material components. The mixture expands after flowing out of the die from the extrusion chamber, which can form micropores.

[0090] In some embodiments, the elongation at break of the first matrix 11 is 1% to 6%. Elongation at break refers to the ratio of the length of the first matrix 11 that continues to extend to the point of fracture after being subjected to the maximum load during the tensile process to the original length. Elongation at break is used to characterize the plastic deformation capacity of the first matrix 11 at tensile fracture.

[0091] The elongation at break of the first matrix 11 is within the aforementioned range, which matches the mechanical requirements of the processing equipment and maintains the morphological stability of the first matrix 11 during combustion. Specifically, the brittleness of the first matrix 11 is suitable to accommodate the tensile deformation of the processing equipment and reduce the generation of debris. In addition, the ductility of the first matrix 11 is moderate to prevent deformation of the first matrix 11 during combustion and ensure that aerosols can be generated uniformly.

[0092] For example, the elongation at break of the first matrix 11 can be any value among 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, and 6%, or a range between any two values.

[0093] In some embodiments, the mass of each meter of the first substrate 11 is 0.15 g to 0.3 g. The mass of each meter of the first substrate 11 refers to the weight of each meter of the first substrate 11 while maintaining a substantially unchanged morphology.

[0094] The mass of the first substrate 11 is within the aforementioned range, which prevents the first substrate 11 from being loosely packed and its combustion rate from being too fast, thus failing to generate sufficient aerosols. It also prevents increased production costs and reduces the likelihood of producing irritating odors due to the increased heat load on the first substrate 11 during combustion. Therefore, by controlling the mass of each meter of the first substrate 11, the production cost and aerosol volume of the first substrate 11 can be balanced.

[0095] For example, the mass of each meter of the first substrate 11 can be any value or a range of any two values ​​from 0.15g, 0.18g, 0.2g, 0.22g, 0.24g, 0.26g, 0.28g, 0.15g, and 0.3g.

[0096] In some embodiments, the quantitative amount of the first matrix 11 is 150 g / m³. 2 Up to 300g / m 2 The quantitative measurement of the first substrate 11 refers to the weight of the first substrate 11 required to cover a unit area while maintaining its approximate shape.

[0097] The quantitative distribution of the first matrix 11 is within the aforementioned range. This prevents insufficient thickness of the first matrix 11 from causing discontinuous combustion and affecting the aerosol concentration. It also prevents the first matrix 11 from obstructing airflow, thus reducing combustion efficiency and increasing tar release. In this way, by optimizing the quantitative distribution of the first matrix 11, the combustion uniformity of the first matrix 11 and the quality of the aerosol are ensured.

[0098] For example, the quantitative amount of the first matrix 11 can be 150 g / m 2 160g / m 2170g / m 2 180g / m 2 190g / m 2 200g / m 2 210g / m 2 220g / m 2 230g / m 2 240g / m 2 250g / m 2 260g / m 2 270g / m 2 280g / m 2 290g / m 2 and 300g / m 2 The value between any one or any two values ​​in the range.

[0099] In some embodiments, the first matrix 11 does not contain wood pulp. It should be understood that since the first matrix 11 in this embodiment is produced by extrusion molding, wood pulp is not required for molding. This reduces costs and minimizes damage to the fiber structure caused by adding wood pulp. Furthermore, it avoids diluting the flavor of the first matrix 11 with wood pulp, allowing users to enjoy the original flavor of the first matrix 11 and enhancing the user experience.

[0100] In some embodiments, the first matrix 11 includes a flavoring component, a skeleton component, a smoke-generating agent component, and a binder component. Based on the total mass of a single first matrix 11, the flavoring component comprises 0.1% to 24%, the skeleton component comprises 35% to 90%, the smoke-generating agent component comprises 5% to 30%, and the binder component comprises 1% to 10%. The skeleton component provides a supporting framework for the prepared first matrix 11, facilitating its formation. It also provides support for other components, such as providing attachment points for the flavoring component, thereby improving the aroma quality of the matrix segment 1. The smoke-generating agent component readily atomizes to generate a large amount of aerosol, thus increasing the aerosol volume and providing the user with a satisfying vaping experience. The flavoring component provides the matrix segment 1 with a characteristic aroma, such as tobacco, thereby enhancing the user's vaping experience. The binder component wets and comes into close contact with the material interfaces of the various components in the first matrix 11, generating intermolecular attraction, thereby binding the powders, liquids, etc., of the component materials.

[0101] In some embodiments, the skeleton component is selected from one or more of renewable biomass raw materials and plant components. On the one hand, the skeleton component provides a stable supporting structure for the prepared first matrix 11; on the other hand, the skeleton component can serve as a combustible component in the first matrix 11, generating aerosols through combustion to provide a puffing experience. During combustion, it can release characteristic aroma components, enhancing the sensory experience of the prepared first matrix 11. Exemplarily, the renewable biomass raw material is selected from one or more of cellulose, hemicellulose, and lignin; the plant component is selected from one or more of tobacco raw materials, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants. Among the renewable biomass raw materials, cellulose and hemicellulose can help shape the matrix segment 1 and maintain its structural stability, while lignin can act as a shaping aid and binder. Endogenous substances in the plant components, such as nicotine, enter the human bloodstream and promote the pituitary gland to produce dopamine, thereby achieving physiological satisfaction. By selecting the skeleton component from the above-mentioned substances, it can help shape the matrix segment 1 and maintain its structural stability, which is beneficial to improving the stability of manufacturing and product performance.

[0102] The proportion of the skeleton component, based on the total mass of a single first matrix 11, is between 35% and 90%. By keeping the proportion of the skeleton component within the aforementioned range, a supporting structure can be provided for the first matrix 11, improving its structural stability. Furthermore, combustible substances can be provided to the first matrix 11, thereby releasing characteristic aroma substances and providing the user with a satisfying inhalation experience. Exemplarily, the proportion of the skeleton component, based on the total mass of a single first matrix 11, can be any value from 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, and 90%, or a range between any two of these values.

[0103] In some embodiments, the flavoring component is selected from one or more of tobacco extracts, aromatic plant extracts, extracts, essential oils, absolutes, megastigmatrienone, neophytadiene, geraniol, nerol, menthol, and raspberry ketone. Using the above-mentioned flavoring components can provide the first matrix 11 with a richer aroma profile, thereby enhancing the user's inhalation experience.

[0104] The proportion of the fragrance component, based on the total mass of a single first matrix 11, is between 0.1% and 24%. Maintaining the proportion of the fragrance component within this range helps to provide suitable aroma components, enhances the user's vaping experience, and avoids problems such as off-flavors caused by excessive fragrance components. For example, the proportion of the fragrance component, based on the total mass of a single first matrix 11, can be any value from 0.1%, 1%, 2%, 5%, 10%, 15%, 18%, 20%, and 24%, or a value within a range of any two values.

Using the above substances as smoke-generating components is beneficial for providing a large amount of smoke, thereby increasing the amount of smoke generated by the first matrix 11. In one embodiment, the smoke-generating component is selected from one or more of raspberry ketone, propylene glycol, glycerol, 1,3-butanediol, tetraethylene glycol, triacetin, triethyl citrate, a mixture of diacetins, triethyl citrate, methyl benzoate, and triglycerides.

[0106] The proportion of the smoke-generating agent component, based on the total mass of a single first matrix 11, is 5% to 30%. Maintaining the proportion of the smoke-generating agent component within this range is beneficial for generating a large amount of smoke, improving the processability of the composition, and facilitating the molding of the first matrix 11. Exemplarily, the proportion of the smoke-generating agent component, based on the total mass of a single first matrix 11, can be any value from 5%, 10%, 15%, 20%, 25%, and 30%, or a value within a range of any two values.

Exemplarily, the proportion of the adhesive component, based on the total mass of a single first matrix 11, can be any value from 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, and 10%, or a range between any two of these values.

[0109] The matrix segment 1 provided in the application embodiments will be described in more detail below with reference to specific embodiments. This application provides 2 comparative examples and 9 embodiments of this application. Please refer to Table 1.

[0110] Comparative Example 1: The matrix segment includes 100% of the first matrix.

[0111] Comparative Example 2: The matrix segment includes a second matrix that accounts for 100%.

[0112] Example 1 of this application: The matrix segment 1 includes a first matrix 11 accounting for 20% and a second matrix 12 accounting for 80%, the second matrix 12 being a filamentous matrix.

[0114] Embodiment 3 of this application: The matrix segment 1 includes a first matrix 11 accounting for 20% and a second matrix 12 accounting for 80%, wherein the second matrix 12 is a granular matrix.

[0115] Example 4 of this application: The matrix segment 1 includes a first matrix 11 accounting for 10% and a second matrix 12 accounting for 90%, the second matrix 12 being a filamentous matrix.

[0121] Table 1

[0122]

[0123] It should be noted that aroma quality refers to the degree of quality and delicacy of the aroma in matrix segment 1, while characteristic aroma intensity refers to the perceived concentration and strength of the aroma in matrix segment 1. The maximum score for aroma quality, characteristic aroma intensity, and visual smoke volume is 10 points each.

[0124] According to Table 1, for Comparative Example 1, the matrix segment comprises 100% of the first matrix, meaning the matrix segment is entirely prepared using the first matrix. Due to the high true density of the first matrix, the filling rate of the matrix segment reaches its minimum, resulting in a relatively large absorption resistance in the matrix segment.

[0125] For Comparative Example 2, the matrix segment comprised 100% of the second matrix, meaning it was entirely prepared using the second matrix. Because the true density of the second matrix was lower than that of the first matrix, the matrix segment had lower draw resistance, but its aroma quality, characteristic aroma intensity, visual smoke volume, ACM, and menthol content were inferior. Therefore, it is necessary to prepare the matrix segment by blending the first and second matrices.

[0126] Referring to Examples 1 to 3 of this application, for the same blending ratio of the first matrix 11 and the second matrix 12, Example 1 is superior to Examples 2 and 3 in many aspects, including filling rate and absorption resistance, aroma quality and characteristic aroma intensity. This is because, when the first matrix 11 is a strip-shaped matrix and the second matrix 12 is a filament-shaped matrix, their morphology, size, true density, etc., are relatively similar. Therefore, the blending effect of the first matrix 11 and the second matrix 12 is better, enabling the first matrix 11 and the second matrix 12 to fill the matrix segment 1 more uniformly.

[0127] Referring to embodiments 4 to 9 of this application, it can be seen from all the data that embodiment 6 is a better choice, that is, the matrix segment 1 includes a first matrix 11 accounting for 40% and a second matrix 12 accounting for 60%, and the second matrix 12 is a filamentous matrix.

[0128] In some embodiments, gaps exist between the plurality of first substrates 11, between the first substrates 11 and the second substrates 12, and between the plurality of second substrates 12. These gaps can serve as airflow channels for the circulation of aerosols and air. The airflow carrying aerosols can flow more smoothly with less airflow resistance, which can significantly reduce suction resistance during the user's suction process and improve the suction experience.

[0129] In some embodiments, a plurality of first substrates 11 are arranged in an orderly manner, and a second substrate 12 fills the gaps between the plurality of first substrates 11.

[0130] Ordered arrangement is the arrangement according to a set rule or sequence.

[0131] The orderly arrangement of multiple first substrates 11 means that multiple first substrates 11 are arranged according to a set rule or order, and the position of each first substrate 11 can be controlled to place the first substrate 11 in a preset position according to the design.

[0132] The second matrix 12 fills the gaps between the multiple first matrices 11. The second matrix 12 can fill the gaps between the first matrices 11 in a disordered or ordered manner.

[0133] Disorder refers to the absence of set rules or order. For example, the second matrix 12 is randomly filled in the gaps of the first matrix 11, and the position of the second matrix 12 can be random.

[0134] For example, please refer to Figure 3 The first matrix 11 and the second matrix 12 are arranged in an ordered manner. Ordered arrangement means that the first matrix 11 and the second matrix 12 are arranged according to a set rule or sequence. For example, please refer to [further details]. Figure 4 Multiple first substrates 11 and multiple second substrates 12 are arranged circumferentially around a first direction, and the multiple first substrates 11 and multiple second substrates 12 are arranged in a nested ring structure or a spiral structure.

[0135] In one embodiment, a plurality of first substrates 11 are arranged circumferentially in a first direction to form a first unit, and a plurality of second substrates 12 are arranged circumferentially in the first direction to form a second unit.

[0136] For example, multiple first units and multiple second units may be nested sequentially layer by layer. Nesting multiple first units and multiple second units sequentially layer by layer means that a second unit is nested between two adjacent first units, and a first unit is nested between two adjacent second units.

[0137] For example, multiple first units may be nested layer by layer to form a first ring, and multiple second units may be nested layer by layer to form a second ring. For example, the first ring may surround the outer periphery of the second ring. Or, for another example, the second ring may surround the outer periphery of the first ring.

[0138] In one embodiment, a plurality of first substrates are circumferentially arranged in a first direction to form a first helical portion, and a plurality of second substrates are circumferentially arranged in the first direction to form a second helical portion.

[0139] For example, multiple first helical sections and multiple second helical sections may be alternately arranged. Alternating arrangement of multiple first helical sections and multiple second helical sections means that a second helical section is arranged between two adjacent first helical sections, and a first helical section is arranged between two adjacent second helical sections.

[0140] For example, multiple first helical portions can be connected sequentially to form a first helical structure, and multiple second helical portions can be connected sequentially to form a second helical structure. For instance, the first helical structure surrounds the outer peripheral surface of the second helical structure. Or, for another example, the second helical structure surrounds the outer peripheral surface of the first helical structure.

[0141] In some embodiments, a plurality of first substrates 11 are arranged in a disordered manner, and a second substrate 12 fills the gaps between the plurality of first substrates 11.

[0142] Multiple first substrates 11 are arranged in a disordered manner, and second substrates 12 can be orderly filled in the gaps between multiple first substrates 11 or disorderly filled in the gaps between multiple first substrates 11.

[0143] For example, please refer to Figure 4The first matrix 11 and the second matrix 12 are arranged in a disordered manner. This means that the first matrix 11 and the second matrix 12 are randomly distributed without any set rules.

[0144] For example, the first matrix 11 may be arranged in an ordered manner and the second matrix 12 may be arranged in a disordered manner; or the first matrix 11 may be arranged in a disordered manner and the second matrix 12 may be arranged in an ordered manner. This application does not limit the specific arrangement of the first matrix 11 and the second matrix 12.

[0145] Please see Figure 5 and Figure 6 This application also provides an aerosol generating article 10, including a matrix segment 1 and at least one functional segment 2 as described in any embodiment of this application, wherein the matrix segment 1 and the functional segment 2 are disposed along a first direction.

[0146] As an example, functional segment 2 may provide at least one of the following: filtration function, adsorption function, aroma enhancement function, dilution function, cooling function, and resistance adjustment function.

[0147] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0148] 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.

[0149] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0150] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0151] Cooling function refers to the function of reducing the temperature of aerosols.

[0152] 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.

[0153] In one embodiment, please refer to Figure 5 Functional segment 2 includes a support segment 21, which can withstand the temperature from the aerosol in matrix segment 1 and maintain its shape. The support segment 21 provides support.

[0154] In one embodiment, please refer to Figure 5 Functional section 2 includes a cooling section 22, which is used to reduce the temperature of the aerosol. This makes the aerosol suitable for users to inhale, avoiding the problem of "scalding the mouth".

[0155] In one embodiment, please refer to Figure 5 and Figure 6Functional section 2 includes a filter section 23, which is used to filter aerosols. For example, filter section 23 can block substances of a target particle size and can also adjust the suction resistance. For instance, filter section 23 can filter large-diameter particles, similar to powdery substances. Aerosols filtered through filter section 23 have a higher particle size uniformity and a smoother taste.

[0156] In one embodiment, please refer to Figure 5 Functional segment 2 includes a front plug segment 24, which can directly contact the matrix segment 1. The main function of the front plug segment 24 is to clean and prevent the matrix segment 1 from falling off.

[0157] In one embodiment, please refer to Figure 5 The fore plug section 24, the matrix section 1, the support section 21, the cooling section 22, and the filter section 23 are connected sequentially along the first direction.

[0158] In another embodiment, please refer to Figure 6 The aerosol generating article 10 may also consist only of a matrix section 1 and a filter section 23, which are arranged along a first direction. In this embodiment, the matrix section 1 can be ignited to generate an aerosol.

[0159] It should be noted that the direction in which the aerosol generating product 10 is inserted into the apparatus and the direction in which the aerosol generating product 10 is removed from the apparatus are both parallel to the first direction.

[0160] In one embodiment, the aerosol generating article 10 includes a coating layer that covers the outer periphery of the matrix section 1 and the outer periphery of the functional section 2. Exemplarily, the functional section 2 includes a front plug section 24, a support section 21, a cooling section 22, and a filter section 23, with the coating layer covering the outer peripheral surfaces of the matrix section 1 and the functional section 2. That is, the outer peripheries of the front plug section 24, the matrix section 1, the support section 21, the cooling section 22, and the filter section 23 are all covered by the coating layer. The coating layer can be a single layer, or two or more layers can be designed according to the design requirements and manufacturing process of the aerosol generating article 10. For example, during manufacturing, the support section 21, the cooling section 22, and the filter section 23 can be first wrapped with a single coating layer, and then another coating layer can be used to wrap the matrix section 1 and the front plug section 24. Of course, other combinations are also possible.

[0161] Regarding the heat-resistant, non-combustible matrix segment 1, this application also provides an aerosol generation system, including an aerosol generation device and an aerosol generation article 10 as described in any embodiment of this application. The aerosol generation device includes a heating element for heating the aerosol generation article 10 to generate aerosol.

[0162] Specifically, the heating element heats the substrate section 1 to generate an aerosol, and the specific method by which the heating element heats the substrate section 1 is not limited.

[0163] For example, the heating element is a resistance heating wire, which is attached to the aerosol generating product 10. After the heating element is turned on, it transfers heat to the matrix segment 1 to generate aerosol in the matrix segment 1. As another example, the heating element is a laser heating device, which irradiates the aerosol generating product 10 with a high-energy laser to raise the temperature of the matrix segment 1, thereby generating aerosol in the matrix segment 1.
