The unit "μg" stands for microgram.

[0042] Please see Figures 1 to 9 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 thickness of the first matrix 11 is less than the hydraulic diameter of the first cross section, and the first cross section is perpendicular to the thickness direction of the first matrix 11. Both the first matrix 11 and the second matrix 12 are used to generate aerosols.

[0043] The hydraulic diameter is the ratio of four times the area of ​​the first cross section to the perimeter of the first cross section.

[0044] The first matrix 11 and the second matrix 12 can be used to generate aerosols by ignition.

[0045] 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.

[0046] 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.

[0047] Please see Figure 1The thickness of the first substrate 11 is less than the hydraulic diameter of the first cross-section, which is perpendicular to the thickness direction of the first substrate 11. That is, the first substrate 11 is approximately flat. This gives the first substrate 11 a large surface area, allowing the second substrate 12 to be placed on top of it, facilitating the filling of the first substrate 11 and the second substrate 12. For example, the first substrate 11 may wrap around the second substrate 12. Alternatively, the second substrate 12 may be sandwiched between two first substrates 11. Thus, the first substrate 11 and the second substrate 12 can be fabricated into substrate segments 1 in different ways as needed, reducing design and manufacturing complexity.

[0048] In addition, the flat first matrix 11 can hold a large amount of fragrance and has a good retention rate, thereby improving the fragrance intensity and consistency of the aerosol inhaled by the user.

[0049] The thickness of the flat first substrate 11 is not limited, as long as the thickness of the first substrate 11 is less than the hydraulic diameter of the first cross section.

[0050] 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.

[0051] In some embodiments, the true density of the second matrix 12 is less than that of the first matrix 11. This gives the first matrix 11 a higher true density, which reduces the fill rate of matrix segment 1 and thus improves the quality of matrix segment 1. Consequently, matrix segment 1 can generate more aerosols.

[0052] True density refers to the actual mass per unit volume of the first matrix 11 in an absolutely dense state, i.e., the density excluding all air channels and micropores. In other words, the volume here does not include the volume of the air channels and micropores of the first matrix 11. Fill rate refers to the volume occupied by a unit mass of matrix segment 1. It can be understood that 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.

[0053] 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. On the other hand, 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.

[0054] 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.

[0055] In some embodiments, the first matrix 11 is a homogeneous tobacco structure, and the second matrix 11 is a natural tobacco structure.

[0056] 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.

[0057] Natural tobacco structure refers to tobacco leaves that have undergone primary processing, such as curing, before being rolled or shredded.

[0058] In some embodiments, the second matrix 12 includes at least one of sheet matrix, filament matrix and particulate matrix.

[0059] For example, the sheet matrix is ​​formed by processing plant materials such as leaves and tobacco stems into reconstituted sheets, and the processing methods include papermaking, slurry making, or roll pressing.

[0060] Filamentous matrix is ​​made by cutting the original leaf and / or the above-mentioned thin film matrix into filaments.

[0061] Granular matrix is ​​made by crushing the original leaf and / or the above-mentioned thin film matrix into dispersed particles with a diameter of millimeters.

[0062] The second matrix 12 may include at least one of sheet matrix, filament matrix, and granular matrix. The second matrix 12 may include only sheet matrix; or it may include only filament matrix; or it may include granular matrix; or it may include two or three of sheet matrix, filament matrix, and granular matrix.

[0063] 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%.

[0064] 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.

[0065] 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.

[0066] 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%.

[0067] In some embodiments, the fill rate of matrix segment 1 is 2 cm. 3 / g to 8cm 3 / g.

[0068] The filling rate of matrix segment 1 is less than 2cm. 3 At a density of / g, the first matrix 11 is too compact, increasing the absorption resistance of matrix segment 1. When the filling rate of matrix segment 1 is greater than 8cm²... 3 At a rate of / g, the smaller mass of matrix segment 1 results in a reduced aerosol volume. With a fill rate within the aforementioned range, matrix segment 1 not only possesses a larger mass to generate a sufficient number of aerosols for user suction, but also prevents excessive suction resistance from affecting user suction.

[0069] For example, the filling rate of the first substrate 11 can be 2 cm. 3 / g, 2.5cm 3 / g, 3cm 3 / g, 3.5cm 3 / g、4cm 3 / g, 4.5cm 3 / g, 5cm 3 / g, 5.5cm 3 / g、6cm 3 / g, 6.5cm 3 / g、7cm 3 / g, 7.5cm 3 / g and 8cm 3 The value between any number in / g or any two numbers within a range.

[0070] 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.

[0071] In some embodiments, please refer to Figure 2The first matrix 11 is a post-extrusion slicing structure. That is, the first matrix 11 is prepared by post-extrusion slicing. Post-extrusion slicing refers to the process where material is pushed by the screw through the action between the barrel and screw of the extruder 20, continuously passing through the die head to form various cross-sectional products or semi-finished products, and then the cross-sectional products or semi-finished products are cut into thin sheet structures by the cutting blade 30. Compared with papermaking, slurry making, and rolling, the forming process of the first matrix 11 is simpler and can fully utilize plant raw materials, reducing material waste and lowering production costs. Furthermore, 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. In other embodiments, the first matrix 11 can also be directly extruded into a flat shape by the extruder 20, and then cut into the required size by a cutting device.

[0072] 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.

[0073] In some embodiments, the true density of the first matrix 11 is 1 g / cm³. 3 Up to 1.5g / cm 3 .

[0074] The true density of the first matrix 11 is less than 1 g / cm³. 3 In this case, the mass of the first matrix 11 is relatively small, resulting in insufficient aerosol quantity and aroma release. When the true density of the first matrix 11 is greater than 1.5 g / cm³... 3 In this case, on the one hand, the first matrix 11 is difficult to achieve from the extrusion process, requiring an extrusion pressure exceeding 170 bar. On the other hand, it would result in the first matrix 11 being too dense, causing the matrix segment 1 to have high suction resistance, making it difficult for aerosols to be released.

[0075] The true density of the first matrix 11 is within the aforementioned range. On the one hand, this prevents the porosity of the first matrix 11 from being too large, which would affect its heat conduction performance during combustion. On the other hand, it avoids the addition of too many additives to the first matrix 11, which would affect its original taste.

[0076] 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.

[0077] In some embodiments, the thickness of the first substrate 11 is 0.1 mm to 0.5 mm; the area of ​​the first cross-section is 4 mm². 2 Up to 100mm 2 .

[0078] When the thickness of the first matrix 11 is less than 0.1 mm, the processing is quite difficult. When the thickness of the first matrix 11 is greater than 0.5 mm, the first matrix 11 is too dense, resulting in a large suction resistance in matrix segment 1. When the thickness of the first matrix 11 is within the above range, the processing difficulty of the first matrix 11, the suction resistance of matrix segment 1, and the amount of aerosol can be balanced.

[0079] For example, the thickness of the first substrate 11 can be any value among 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm and 0.5 mm or a value between any two values.

[0080] The area of ​​the first cross-section is less than 4mm². 2 In cases where the area of ​​the first cross-section is greater than 100 mm², the processing becomes quite difficult. 2 In this case, the difficulty of filling the first substrate 11 increases. The area of ​​the first cross-section being within the aforementioned range can balance the processing difficulty and filling difficulty of the first substrate 11.

[0081] For example, the area of ​​the first cross-section can be 4 mm². 2 10mm 2 20mm 2 30mm 2 40mm 2 50mm 2 60mm 2 70mm 2 80mm 2 90mm 2 and 100mm 2 The value between any one or any two values ​​in the range.

[0082] 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.

[0083] When the tensile strength of the first matrix 11 is below 0.15 kN / m, it is prone to breakage during processing and transportation. When the tensile strength of the first matrix 11 is above 0.15 kN / m, processing becomes more difficult. When the tensile strength of the first matrix 11 is within the aforementioned range, the processing difficulty is moderate, which can also improve the mechanical strength of the first matrix 11 and prevent breakage during processing and transportation.

[0084] 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.

[0085] In some embodiments, the combustion rate of the first substrate 11 is from 0.1 mm / s to 0.7 mm / s.

[0086] For the matrix section 1 that generates aerosols by ignition, if the combustion rate of the first matrix 11 is less than 0.1 mm / s, the amount of aerosol released per unit time will decrease, affecting the user's sensory experience. If the combustion rate of the first matrix 11 is greater than 0.1 mm / s, the first matrix 11 will be wasted because the user will not continuously inhale, thus reducing the product's cost-effectiveness.

[0087] The combustion rate of the first substrate 11 is within the above-mentioned range, which is beneficial to the temperature and release amount of the aerosol, so as to match the user's breathing rhythm and prevent the waste of the first substrate 11.

[0088] 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, 0.6 mm / s, and 0.7 mm / s, or a value between any two of these values.

[0089] In some embodiments, please refer to Figures 3 to 5 The first cross-section can be circular, quadrilateral, star-shaped, or irregularly shaped. For example, the first cross-section can be circular; the first cross-section can also be quadrilateral; the first cross-section can also be star-shaped; the first cross-section can also be irregularly shaped. Thus, different shapes of the first cross-section can be used as needed to facilitate filling with different types of second substrates 12.

[0090] For example, please refer to Figure 4 The first cross section can be in the shape of a four-pointed star.

[0091] For example, please refer to Figure 5 The first cross-section can also be shaped like a smiley face.

[0092] In other embodiments, the first cross-section of different first substrates 11 may be two, three, or four of the following: circular, quadrilateral, star-shaped, and irregular shapes.

[0093] 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.

[0094] Ordered arrangement is the arrangement according to a set rule or sequence.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] As an example, a plurality of first substrates 11 are stacked along the thickness direction, and a plurality of second substrates 12 are randomly filled in the gaps between the plurality of first substrates 11.

[0099] In some embodiments, please refer to Figure 6 The second substrate 12 is a thin sheet substrate, and multiple first substrates 11 and multiple second substrates 12 are stacked along the thickness direction. That is, the first substrates 11 and the second substrates 12 are arranged in an orderly manner, and the second substrates 12 are filled in the gaps between multiple first substrates 11 in an orderly manner according to the design.

[0100] For example, please continue reading Figure 6 Multiple first substrates 11 and multiple second substrates 12 are arranged alternately along the thickness direction. That is, the first substrates 11 and the second substrates 12 are adjacent to each other. For example, a second substrate 12 is stacked between any two first substrates 11. In this way, the first substrates 11 and the second substrates 12 can be uniformly filled.

[0101] For example, multiple first substrates 11 can be stacked along the thickness direction to form a first unit, and multiple second substrates 12 can be stacked along the thickness direction to form a second unit, with the first unit and the second unit stacked along the thickness direction.

[0102] In some embodiments, please refer to Figure 7 , Figure 10 and Figure 11 Multiple first substrates 11 and multiple second substrates 12 are filled in a disordered manner. That is, the first substrates 11 and the second substrates 12 are randomly distributed. In this way, the first substrate 11 can be filled with one or more second substrates 12 of any shape, such as sheet substrates, filamentous substrates and granular substrates. By making full use of the first substrates 11 and the second substrates 12, production costs can be reduced.

[0103] In other embodiments, the first matrix 11 may be arranged randomly 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.

[0104] In some embodiments, the first matrix 11 has air channels that pass through at least one end face of the first matrix 11 along its thickness direction. For example, the air channel passes through one end of the first matrix 11 along its thickness direction. Alternatively, the air channel passes through both end faces of the first matrix 11 along its thickness direction. Airflow can flow from one end of the first matrix 11 along the air channels to the other end of the first matrix 11. Aerosols can flow more smoothly through the air channels, aerosols can be delivered in an orderly manner, aerosol flow resistance is lower, and controllability is better, effectively improving aerosol extraction efficiency and enhancing the suction experience.

[0105] In one embodiment, the airway may be formed inside the first matrix 11 or on the outer peripheral surface of the first matrix 11.

[0106] In one embodiment, the air passage is a straight air passage extending in a straight line. Straight air passages are easy to form, reducing manufacturing difficulty. The flow resistance within a straight air passage is relatively low.

[0107] In one embodiment, the airway is a curved airway, and at least a portion of the pores of the curved airway has a non-zero curvature. The curved airway can significantly increase the flow path of the airflow without significantly increasing the length of the first matrix 11, and can prolong the contact time between the airflow and the pore wall of the curved airway, thereby improving the aerosol extraction rate.

[0108] In one embodiment, the curved airway is helical. That is, the three-dimensional shape of the curved airway is a spatial spiral. For example, the helical curved airway can be formed by rotating the die during the extrusion process. The line connecting any point of the helical curved airway to the starting point has an angle of inclination relative to its axis. The helical curved airway can greatly extend the flow path of the airflow, causing the aerosol to be released from the first matrix 11 into the curved airway, increasing the flow velocity of the aerosol in the first matrix 11, thereby increasing the impact force of the airflow, enabling the aerosol to be uniformly mixed, improving aerosol uniformity, and enhancing the user's suction experience.

[0109] The cross-sectional shape of the airway located inside the first matrix 11 is not limited. For example, the cross-sectional shape can be circular, polygonal (including but not limited to triangle, square, rhombus, etc.), elliptical, racetrack-shaped, or irregular, etc. Among them, irregular refers to other symmetrical or asymmetrical shapes other than those listed above.

[0110] The cross-sectional shape of the airway located on the outer peripheral surface of the first matrix 11 can be semi-circular, semi-elliptical, polygonal, or irregular, etc. Among them, irregular refers to other symmetrical or asymmetrical shapes other than those listed above.

[0111] It should be noted that the airway described in this application is different from the micropore. The airway described in this application is a pore in a macroscopic sense, while the micropore is a pore in a microscopic sense. The cross-sectional area and length of the airway are much larger than those of the micropore.

[0112] 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 an extruded and sliced ​​structure, wood pulp is not required for molding. This reduces costs and minimizes large-scale 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 extract the original flavor of the first matrix 11 and improving the user experience.

[0113] 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 aerosol production 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] In some embodiments, the smoke-generating component is selected from one or more of the following options: monohydric alcohol; dihydric alcohol; polyhydric alcohol; esters formed from monocarboxylic acid, dicarboxylic acid, or polycarboxylic acid and fatty alcohol. 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.

[0119] 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.

[0120] In some embodiments, the adhesive component is selected from one or more of tamarind polysaccharide, guar gum, and modified cellulose, wherein the modified cellulose is selected from one or more of sodium carboxymethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose.

[0121] The proportion of the adhesive component, based on the total mass of a single first matrix 11, is between 1% and 10%. Maintaining the proportion of the adhesive component within this range is beneficial for improving the structural stability of the prepared first matrix 11. 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.

[0122] 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.

[0123] Comparative Example 1: The matrix segment includes 100% of the first matrix.

[0124] Comparative Example 2: The matrix segment includes a second matrix that accounts for 100%.

[0125] 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%, wherein the second matrix 12 is a sheet matrix.

[0126] Embodiment 2 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.

[0127] 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.

[0134] Table 1

[0135]

[0136] 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 off-odors is 10 points each.

[0137] 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.

[0138] 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 is ​​lower than that of the first matrix, the matrix segment had lower absorption resistance, but its aroma quality, characteristic aroma intensity, off-odors, aldehyde and ketone content, and menthol content were unsatisfactory. Therefore, it is necessary to prepare the matrix segment by blending the first and second matrices.

[0139] 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 both the first matrix 11 and the second matrix 12 are thin-film matrices, 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.

[0140] 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 sheet matrix.

[0141] Please see Figure 8 and Figure 9 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.

[0142] 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.

[0143] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0144] 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.

[0145] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0146] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0147] Cooling function refers to the function of reducing the temperature of aerosols.

[0148] 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.

[0149] In one embodiment, please refer to Figure 8 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.

[0150] In one embodiment, please refer to Figure 8 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".

[0151] In one embodiment, please refer to Figure 8 and Figure 9 Functional 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.

[0152] In one embodiment, please refer to Figure 8 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.

[0153] In one embodiment, please refer to Figure 8 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.

[0154] In another embodiment, please refer to Figure 9The 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.

[0155] It should be noted that the direction in which the aerosol-generating product 10 of functional segment 2 and matrix segment 1 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.
