Description

Technical Field

[0001] This application relates to the field of smoke-generating products, and in particular to an aerosol-generating product and an aerosol-generating system. Background Technology

[0002] Smoke-generating products typically include aerosol-generating products that form aerosols by ignition or heating without combustion. During the use of a typical heated but non-combustible aerosol-generating product, heat is transferred from a heat source to the matrix section of the aerosol-generating product, causing the matrix section to release volatile compounds. These volatile compounds are carried into the air containing the aerosol-generating product when the user inhales it. As the released volatile compounds cool, they condense to form an aerosol.

[0003] In related technologies, aerosol-generating products based on heating without combustion have a significantly lower heating temperature than ignition-type aerosol-generating products. As a result, the aroma substances in the matrix segment cannot be fully released, leading to a decrease in both the amount and quality of aroma in the aerosol. When users inhale, the aroma components are not sufficient, resulting in a relatively poor inhalation experience. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide an aerosol generating article and an aerosol generating system, which are intended to improve the aroma concentration of the aerosol, thereby improving the inhalation experience of the aerosol.

[0005] To solve the above problems, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides an aerosol generating article, comprising:

[0007] The matrix segment is used to generate aerosols;

[0008] The front plug section is located at one end of the matrix section along its axial direction and upstream of the matrix section;

[0009] A porous structure segment is disposed upstream or downstream of the matrix segment, and the interior of the porous structure segment has at least one first air passage hole, which passes through at least one end of the porous structure segment along its axial direction.

[0010] The downstream section is located downstream of the matrix section. The downstream section includes a supporting cooling section, a filtering section, and an airflow gathering section. The airflow gathering section is provided with a flow gathering channel that runs through the opposite ends of the airflow gathering section along its axial direction.

[0011] In some embodiments, the diameter of the flow-gathering channel remains constant along its axial direction; or,

[0012] The flow channel includes a converging section, the diameter of which gradually decreases from one end near the matrix section to the other end away from the matrix section.

[0013] In some embodiments, the number of convergent channels is multiple, and on the cross-section of the airflow gathering section, all the convergent channels are at least divided into a first convergent channel and a second convergent channel. The second convergent channel surrounds the outer periphery of the first convergent channel, wherein the maximum diameter of any convergent channel in the second convergent channel is smaller than the maximum diameter of any convergent channel in the first convergent channel; and / or,

[0014] The maximum diameter of the flow-gathering channel is 1mm to 6mm.

[0015] In some embodiments, the airflow gathering section is located at the end of the downstream section away from the matrix section; and / or,

[0016] The material of the airflow gathering section includes at least one of cellulose acetate, polylactic acid, and polyethylene terephthalate.

[0017] In some embodiments, the porous structure segment is loaded with at least one of an atomizing agent, a fragrance substance, a harm-reducing and tar-reducing material, and an adsorbent material.

[0018] In some embodiments, the porous structure segment is disposed adjacent to the matrix segment along the axial direction of the aerosol-generated article.

[0019] In some embodiments, the porous structure segment is disposed between the forepump segment and the matrix segment.

[0020] In some embodiments, the matrix section and the filter section are respectively located at opposite axial ends of the supporting cooling section, and the airflow gathering section is located at the end of the filter section away from the supporting cooling section; and / or,

[0021] The porous structure section and / or the airflow gathering section are an integral structure.

[0022] In some embodiments, the length of the airflow gathering section accounts for 6% to 20% of the length of the aerosol-generating article; and / or,

[0023] The length of the filter section accounts for 10% to 30% of the length of the aerosol-generated product.

[0024] In some embodiments, the length of the matrix segment accounts for 10% to 40% of the length of the aerosol-generated article; and / or,

[0025] The interior of the matrix segment has at least one second airway hole, which passes through at least one end of the matrix segment along its axial direction.

[0026] In some embodiments, the length of the porous structure segment accounts for 10% to 30% of the length of the aerosol-generating article; and / or, the length of the foreplug segment accounts for 5% to 32% of the length of the aerosol-generating article.

[0027] This application also provides an aerosol generation system, including:

[0028] Aerosol-generating articles as described in any of the above embodiments;

[0029] An aerosol generating apparatus includes a heating component for heating the aerosol generating article to generate an aerosol.

[0030] The aerosol generating article of this application embodiment is provided with a porous structure section. By adjusting the shape, size, and distribution of the pores in the porous structure section, the air intake and air distribution ratio of the aerosol generating article can be regulated. Thus, the porous structure section, in conjunction with the matrix section, facilitates the entry of sufficient air into the matrix section, allowing the volatile compounds released by the matrix section to condense and form aerosols. At the same time, the air intake can also be controlled, which is beneficial to increasing the content of aroma substances in the aerosol, thereby improving the aroma concentration of the aerosol. Meanwhile, an airflow gathering section is provided downstream of the matrix section, and a convergence channel is provided on the airflow gathering section. The airflow encounters less resistance in the convergence channel, making it easier for the airflow to pass through. Therefore, a large amount of airflow will flow through the convergence channel and through the airflow gathering section, thereby flowing to the near-lip end of the aerosol generating article. That is, the airflow gathering section can collect the aerosol, thereby improving the concentration of the aerosol and thus improving the aroma concentration, thereby improving the inhalation experience of the aerosol.

[0045] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0046] This application provides an aerosol-generating product; please refer to [link / reference]. Figure 1 The aerosol-generating product 100 includes a matrix section 10, a pre-plug section 20, a porous structure section 30, and a downstream section 40.

[0047] The shape of the aerosol generating article 100 is not limited. For example, the aerosol generating article 100 may be a conical structure, a frustum structure, or a cylindrical structure.

[0048] Preferably, the aerosol generating product 100 has a cylindrical structure. Further, the aerosol generating product 100 can have a cylindrical structure, which facilitates manufacturing and processing.

[0049] The aerosol generating product 100 is suitable for suction by heating without combustion.

[0050] The matrix segment 10 is used to generate aerosols. Specifically, the aerosol generating article 100 is used in conjunction with an aerosol generating device, which includes a heating component and a power supply component. The power supply component provides electrical energy to the heating component, which converts the electrical energy into other forms of energy and applies them to the matrix segment 10, thereby heating the matrix segment 10 to generate aerosols.

[0051] There are various heating methods for the heating components. For example, heating methods include peripheral heating and center heating. Peripheral heating refers to the heating component being positioned around the periphery of the aerosol-generating article 100 to bake and heat the matrix segment 10 from the outside in. Center heating refers to the heating component being inserted into the interior of the aerosol-generating article 100 to bake and heat the matrix segment 10 from the inside out. These heating methods can specifically include resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc., and are not specifically limited herein.

[0052] Please see Figure 1 The aerosol generating article 100 has two axial ends, namely a proximal lip end 100a and a distal lip end 100b. The proximal lip end 100a refers to the end of the aerosol generating article 100 that is close to the user's lips when the user uses it, and the distal lip end 100b refers to the end of the aerosol generating article 100 that is far away from the user's lips when the user uses it.

[0053] During the suction process, a portion of the airflow can flow from the distal lip end 100b to the proximal lip end 100a, thereby entraining the aerosol generated by the matrix section 10 for the user to inhale. It can be understood that the area through which this portion of the airflow flows after passing through the matrix section 10 is the downstream of the matrix section 10, and the area through which it flows before reaching the matrix section 10 is the upstream of the matrix section 10.

[0054] The front plug section 20 is located at one end of the matrix section 10 along its axial direction and upstream of the matrix section 10.

[0055] Specifically, the axial direction of the aerosol-generating product 100 is as follows: Figure 1 As shown in Figure D, the axial direction of the front plug section 20, the axial direction of the matrix section 10, the axial direction of the porous structure section 30, and the axial direction of the downstream section 40 are all in the same direction as the axial direction of the aerosol generating product 100.

[0056] Aerosol generating devices typically include a receiving chamber where the aerosol-generated product 100 is placed for use. During use, the front plug section 20 effectively reduces the likelihood of the matrix section 10 falling off. Simultaneously, after the user finishes pumping, some aerosol tends to condense and flow back under gravity, forming condensate in the receiving chamber. The front plug section 20 effectively absorbs this condensate, preventing the aerosol from flowing downwards after condensation and remaining in the receiving chamber, thus avoiding contamination and difficulty in cleaning, and also mitigating the potential cross-contamination of flavors when pumping different flavored aerosol-generated products 100.

[0057] The porous structure segment 30 is located upstream or downstream of the matrix segment 10.

[0058] The porous structure segment 30 has at least one first air passage hole inside, which passes through at least one end of the porous structure segment 30 in the axial direction.

[0059] The porous structure segment 30 has at least one first airway hole inside. It can be that the porous structure segment 30 has one first airway hole inside, or it can have multiple first airway holes inside.

[0060] It should be noted that the "multiple" mentioned in the embodiments of this application refers to two or more.

[0061] In some embodiments, the first airway hole passes through the same end of the porous structure segment 30 along the axial direction, while the other end is closed.

[0062] In other embodiments, a portion of the first airway hole passes through one end of the porous structure segment 30 in the axial direction, and another portion of the first airway hole passes through the other end of the porous structure segment 30 in the axial direction.

[0063] In some embodiments, each first air passage extends through both ends of the porous structure segment 30 along its axial direction; that is, the first air passage extends along the axial direction of the porous structure segment 30, allowing airflow to flow from one end of the porous structure segment 30 through the first air passage to the other end. Preferably, the first air passage is parallel to the central axis of the porous structure segment 30.

[0064] It should be noted that the shape of the first airway hole is not limited here. For example, on a plane perpendicular to the axial direction of the porous structure segment 30, the cross-sectional shape of the first airway hole is, but is not limited to, a circle, an ellipse, a racetrack shape, or a polygon. Among them, the polygon includes regular or irregular polygons, and the polygon includes convex polygons and concave polygons (such as pentagrams, hexagons, etc.).

[0065] Among them, the track shape refers to a shape similar to an athletic track, which is formed by two semicircles and two parallel straight sides connected alternately.

[0066] The cross-sectional shape of the first airway refers to the cross-sectional shape of the first airway as obtained by cutting along a plane perpendicular to the axial direction of the porous structure segment 30.

[0067] In addition, the cross-sectional shape of each of the first airway holes can be exactly the same, or at least two of the first airway holes can have different cross-sectional shapes. For example, at least one of the first airway holes can have a circular cross-sectional shape, and at least one of the first airway holes can have a polygonal cross-sectional shape.

[0068] When the porous structure section 30 is provided with multiple first air passage holes, the distribution of the first air passage holes on the cross-section of the porous structure section 30 is not limited.

[0069] For example, each of the first airway holes is distributed in a radial pattern on the cross-section of the porous structure segment 30.

[0070] A radial distribution refers to setting a center on the cross-section and setting multiple concentric circles of different diameters around the center, with multiple first airway holes distributed on the circumference of each circle.

[0071] For example, each of the first airway holes is distributed in a matrix on the cross-section of the porous structure segment 30.

[0072] Matrix distribution refers to setting multiple trajectory lines on a cross-section, with each trajectory line arranged at intervals along the direction that intersects (or is orthogonal) its extension direction, and multiple first airway holes distributed on each trajectory line.

[0073] In some embodiments, the interior of the matrix segment 10 has at least one second airway hole that passes through at least one end of the matrix segment 10 in the axial direction.

[0074] The number, shape, and arrangement of the second airway holes on the matrix segment 10 can be understood with reference to the first airway holes, and will not be repeated here.

[0075] It should be noted that the second airway orifice is also a macroscopic orifice.

[0076] It should be noted that the matrix segment 10 has micropores, which are interconnected to form micro-airways communicating with the second airway pores. It is understood that the interconnection between micropores can be partial, with some micropores not interconnected, or all micropores can be interconnected. For example, in an embodiment where the matrix segment 10 is a particle aggregate, the gaps between the particles constitute the micropores. The size of the micropores is determined by the gaps between the particles.

[0077] The second air duct and micro-air ducts can increase the surface area of ​​the matrix segment 10, facilitating heat transfer and improving heating efficiency. When heated, the aerosol generating matrix of the matrix segment 10 releases aerosols, which are collected into the second air duct through the gaps between the wall materials or the micro-air ducts. The aerosols released by the aerosol generating matrix exposed to the second air duct (i.e., the aerosol generating matrix located on the inner wall surface of the second air duct) can be directly released into the second air duct. The aerosols between adjacent second air ducts can also flow between each other through the micro-air ducts and be transported to the proximal lip under the action of suction negative pressure.

[0078] Here, the first airway hole and the second airway hole are fitted together, which facilitates the removal of volatile compounds generated by the matrix section 10 by air, thereby condensing and generating aerosols. This is beneficial for the release of volatile compounds, increases the aerosol concentration in the suction airflow, and thus improves the suction experience.

[0079] The porous structure segment 30 can at least be used to regulate the air intake of the aerosol-generating product 100.

[0080] The forming method of the porous structure segment 30 is not limited. For example, the porous structure segment 30 is an integral structure obtained by extrusion, injection molding, casting, etc.

[0081] "Integrated structure" refers to a continuous material body formed by the components of the porous structure segment 30 through a manufacturing process, whose structural integrity does not depend on fastening or connecting components assembled later. For example, materials used to prepare the porous structure segment 30 are mixed to form a preparation slurry, and the preparation slurry is used to produce the porous structure segment 30 through an integrated molding device.

[0082] Extrusion molding is a processing method in which a slurry is added to an extrusion device, and the slurry is pushed forward by the screw through the action between the barrel and the screw of the extrusion device, and continuously passed through the die at the outlet of the extrusion device to produce various cross-sectional products or semi-finished products.

[0083] The porous structure section 30 allows for adjustment of the air intake and air distribution ratio of the aerosol-generating product 100 by modifying the shape, size, and distribution of the pores. Thus, when used in conjunction with the matrix section 10, the porous structure section 30 facilitates the entry of sufficient air into the matrix section 10, causing the volatile compounds released by the matrix section 10 to condense and form aerosols. Simultaneously, the air intake can be controlled, which is beneficial for increasing the content of aroma substances in the aerosol, thereby improving the aroma concentration of the aerosol.

[0084] It should be noted that the aforementioned first airway pore is a pore in a macroscopic sense, while the micropore is a pore in a microscopic sense. The cross-sectional area of ​​the first airway pore is much larger than that of the micropore; for example, the diameter of the first airway pore is at least 20 times that of the micropore. In this embodiment, the porous structure segment 30 refers to the porous structure segment 30 having a first airway pore, that is, the porous structure segment 30 having a pore in a macroscopic sense.

[0085] The downstream section 40 is located downstream of the matrix section 10. The downstream section 40 includes a supporting cooling section 41, a filtering section 42, and an airflow gathering section 43. The airflow gathering section 43 is provided with a flow gathering channel 43a, which runs through the opposite ends of the airflow gathering section 43 along its axial direction.

[0086] The cooling support section 41 provides support and also reduces the temperature of the aerosol, ensuring that the temperature of the aerosol flowing out from the near-lip end 100a is suitable and preventing the aerosol from burning your mouth. The filtration section 42 is used to filter the aerosol.

[0087] By providing an airflow gathering section 43 on the aerosol generating article 100, and a converging channel 43a on the airflow gathering section 43, the airflow encounters less resistance within the converging channel 43a, allowing the airflow to pass through more easily. Therefore, a large amount of airflow flows through the converging channel 43a and then through the airflow gathering section 43, reaching the near-lip end 100a of the aerosol generating article 100. In other words, the airflow gathering section 43 can concentrate the aerosol, thereby improving the concentration of the aerosol and consequently, the concentration of the aroma, thus improving the inhalation experience of the aerosol.

[0088] The forming method of the airflow gathering section 43 is not limited. For example, the airflow gathering section 43 can also be an integral structure obtained by extrusion, injection molding, casting, etc. Here, the integral structure airflow gathering section 43 can be understood with reference to the explanation of the integral structure porous structure section 30, which will not be repeated here.

[0089] In related technologies, aerosol-generating products based on heating without combustion have a significantly lower heating temperature than ignition-type aerosol-generating products. As a result, the aroma substances in the matrix segment cannot be fully released, leading to a decrease in both the amount and quality of aroma in the aerosol. When users inhale, the aroma components are not sufficient, resulting in a relatively poor inhalation experience.

[0090] The aerosol generating product 100 of this application embodiment is provided with a porous structure section 30. By adjusting the shape, size and distribution of the pores in the porous structure section 30, the air intake and air distribution ratio of the aerosol generating product 100 can be adjusted. In this way, the porous structure section 30 is used in conjunction with the matrix section 10 to facilitate the entry of sufficient air into the matrix section 10, so that the volatile compounds released by the matrix section 10 condense to form aerosols. At the same time, the air intake can also be controlled, which is beneficial to increasing the content of aroma substances in the aerosol, thereby improving the aroma concentration of the aerosol. Meanwhile, an airflow gathering section 43 is provided downstream of the matrix section 10, and a convergence channel 43a is provided on the airflow gathering section 43. The airflow encounters less resistance when flowing in the convergence channel 43a, and the airflow passes through more easily. Therefore, a large amount of airflow will flow through the convergence channel 43a and pass through the airflow gathering section 43, thereby flowing to the near-lip end 100a of the aerosol generating product 100. That is, the airflow gathering section 43 can gather the aerosol, which is beneficial to improve the concentration of the aerosol, thereby improving the concentration of the aroma and improving the inhalation taste of the aerosol.

[0091] It should be noted that the shape of the flow channel cross-section of the flow converging channel 43a is not limited. For example, the shape of the flow channel cross-section of the flow converging channel 43a includes at least one of a circle, a regular polygon, and an ellipse. In this way, the shape of the flow channel cross-section of the flow converging channel 43a is more regular, which facilitates molding and helps to improve the production efficiency and yield of the airflow converging section 43.

[0092] It is understandable that the flow channel cross section of the flow convergence channel 43a is perpendicular to the axis of the flow convergence channel 43a.

[0093] In some embodiments, please refer to Figure 2 Along the axial direction of the flow-gathering channel 43a, the diameter of the flow-gathering channel 43a remains unchanged.

[0094] In other words, by using a plane perpendicular to the axis of the flow-gathering channel 43a to cut the flow-gathering channel 43a, the area and shape of the cross-section of the flow-gathering channel 43a are the same at any position along the axis of the airflow gathering section 43.

[0095] It should be noted that in this embodiment, the axis of the flow-gathering channel 43a can be at an angle to the axis of the airflow gathering section 43, or they can be parallel. When the axis of the flow-gathering channel 43a is parallel to the axis of the airflow gathering section 43, that is, along the axis of the airflow gathering section 43, the diameter of the flow-gathering channel 43a remains unchanged.

[0096] In this embodiment, when setting the flow-concentrating channel 43a, since the diameter of the flow-concentrating channel 43a does not need to be changed, the operation of setting the flow-concentrating channel 43a is relatively convenient and facilitates the formation of the flow-concentrating channel 43a.

[0097] In some embodiments, please refer to Figure 3 and Figure 4 The convergence channel 43a includes a converging section 43a1, which gradually decreases in diameter from one end near the matrix section 10 to the end away from the matrix section 10. Thus, as the airflow passes through the converging section 43a1, it enters from the larger diameter end and exits from the smaller diameter end. This helps to further increase the concentration of aerosols, thereby improving the concentration of aroma and enhancing the taste of the aerosols.

[0098] Please see here. Figure 3 The converging channel 43a can be formed by the tapering section 43a1. In this way, the overall structure of the converging channel 43a is relatively simple and easy to manufacture.

[0099] Please see here. Figure 4The converging channel 43a includes a converging section 43a1, a throat section 43a2, and a flaring section 43a3. The throat section 43a2 is located at the end of the converging section 43a1 furthest from the matrix section 10, and the flaring section 43a3 is located at the end of the throat section 43a2 furthest from the converging section 43a1. From the end closest to the matrix section 10 to the end furthest from the matrix section 10, the diameter of the throat section 43a2 remains constant, while the diameter of the flaring section 43a3 gradually decreases. Thus, the converging channel 43a is roughly formed as a Venturi structure to create the Venturi effect (the Venturi effect refers to the phenomenon that the fluid velocity increases when passing through a narrowed flow cross-section, and its velocity is inversely proportional to the flow cross-section). Aerosols can pass through the converging channel 43a relatively quickly, thereby allowing for faster aerosol extraction.

[0100] In some embodiments, please refer to Figure 5 and Figure 6 There are multiple flow-gathering channels 43a. On the cross-section of the airflow gathering section 43, all flow-gathering channels 43a are divided into at least a first flow-gathering channel 431 and a second flow-gathering channel 432. The second flow-gathering channel 432 surrounds the outer periphery of the first flow-gathering channel 431. The maximum diameter of any flow-gathering channel 43a in the second flow-gathering channel 432 is smaller than the maximum diameter of any flow-gathering channel 43a in the first flow-gathering channel 431.

[0101] The maximum diameter of the flow-converging channel 43a refers to the distance between the two furthest points on the cross-section of the flow-converging channel 43a. For example, when the cross-section of the flow-converging channel 43a is circular, its maximum diameter is the diameter of the circle. For example, when the cross-section of the flow-converging channel 43a is square, its maximum diameter is the length of the diagonal of the square.

[0102] It should be noted that the cross-section of the airflow gathering section 43 refers to the cross-section perpendicular to the axial direction of the airflow gathering section 43.

[0103] It should be noted that there are no restrictions on the arrangement of the multiple flow-gathering channels 43a on the cross-section of the airflow gathering section 43.

[0104] For example, please refer to Figure 5 Multiple flow-converging channels 43a are arranged in a radial pattern on the cross-section of the airflow convergence section 43. The specific distribution pattern of the radial pattern can be understood with reference to the explanation of the radial distribution of the first air passage holes mentioned above, and will not be repeated here.

[0105] For example, please refer to Figure 6Multiple flow-converging channels 43a are distributed in a matrix on the cross-section of the airflow convergence section 43. The specific distribution method of the matrix distribution can also be understood with reference to the aforementioned explanation of the matrix distribution of the first air passage orifice, and will not be repeated here.

[0106] It should be noted that the entire convergence channel 43a may be divided into only the first convergence channel 431 and the second convergence channel 432, or it may also include the third convergence channel 433, or even the fourth convergence channel, the fifth convergence channel, etc. This application does not impose any restrictions here.

[0107] The shape and maximum diameter of each flow-concentrating channel 43a within the first flow-concentrating channel 431 can be all the same, or at least two flow-concentrating channels 43a can have different shapes and / or maximum diameters.

[0108] The shape and maximum diameter of each flow-concentrating channel 43a within the second flow-concentrating channel 432 can be all the same, or at least two flow-concentrating channels 43a can have different shapes and / or maximum diameters.

[0109] The shape and maximum diameter of each flow-converging channel 43a in the third flow-converging channel 433, the fourth flow-converging channel, etc., can all be the same. Of course, there can also be at least two flow-converging channels 43a with different shapes and / or maximum diameters.

[0110] Please see Figure 5 and Figure 6 The first part, convergence channel 431, refers to all convergence channels 43a within the area enclosed by line L1; the second part, convergence channel 432, refers to all convergence channels 43a within the area between line L2 and line L1; and the third part, convergence channel 433, refers to all convergence channels 43a within the area between line L3 and line L2.

[0111] In this embodiment, the maximum diameter of the flow-gathering channel 43a near the axis of the airflow gathering section 43 is larger than the diameter of the flow-gathering channel 43a located around the periphery of the airflow gathering section 43. This facilitates the flow of airflow through the vicinity of the central axis of the airflow gathering section 43, thereby helping to collect aerosols and thus improve the concentration of the aroma of the aerosols.

[0112] In some embodiments, please refer to Figure 1 The maximum diameter of the flow-gathering channel 43a is 1mm to 6mm. For example, it can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc.

[0113] In this embodiment, the maximum diameter range of the converging channel 43a is reasonable. On the one hand, the maximum diameter is not less than 1 mm, so the converging channel 43a has good permeability, which helps to ensure the amount of smoke and the suction resistance during inhalation is not too high. On the other hand, the maximum diameter is not greater than 6 mm, which helps to ensure the concentration effect of the converging channel 43a on aerosols. At the same time, it can reasonably control the amount of volatile compounds released by the matrix section 10, which helps to improve the problem that the matrix section 10 releases a large amount of volatile compounds in the early stage of inhalation and insufficient release of volatile compounds in the later stage of inhalation, resulting in poor consistency before and after inhalation.

[0114] In some embodiments, please refer to Figure 1 The airflow gathering section 43 is located at the end of the downstream section 40 away from the matrix section 10. That is, the end of the airflow gathering section 43 away from the matrix section 10 constitutes the lip end 100a of the aerosol generating article 100.

[0115] Understandably, the aerosol is more concentrated and the aroma is more concentrated at the outlet of the convergence channel 43a. In this embodiment, the aerosol flowing out of the convergence channel 43a is directly inhaled. At this time, the concentration of aerosol inhaled by the user is higher and the aroma is stronger, which is conducive to further improving the inhalation taste of the aerosol-generated product 100.

[0116] Of course, the positions of the three sections of the downstream section 40 can be arbitrarily interchanged. That is, the airflow gathering section 43 can be located at the end of the downstream section 40 near the matrix section 10, or between the filtration section 42 and the support cooling section 41. In this way, a concentration effect on aerosols can be achieved.

[0117] In some embodiments, please refer to Figure 1 The material of the airflow gathering section 43 includes at least one of cellulose acetate (CA), polylactic acid (PLA), and polyethylene terephthalate (PET).

[0118] Fiber acetate has excellent filtration properties. It can effectively filter out harmful substances in aerosols, such as nicotine and tar, thereby reducing the harm these substances pose to users.

[0119] Polylactic acid (PLA) is a bio-based material derived from starchy grains such as corn and potatoes, or from the cellulose in crop straw. It is renewable and biodegradable. Using PLA to prepare the airflow converging section 43 can reduce dependence on petroleum resources and lower environmental pollution. Furthermore, PLA possesses excellent physical properties, such as good thermal stability, and is suitable for various processing methods, including extrusion, spinning, biaxial stretching, and injection blow molding, thus facilitating the production of the airflow converging section 43.

[0120] PET material possesses excellent heat resistance, thus it is less prone to deformation or failure. PET exhibits good chemical stability, resisting the erosion of various chemicals and solvents, and does not release harmful substances during heating, contributing to the safety and stability of the aerosol-generated product 100. PET also boasts superior processing performance, which helps improve the production efficiency and reduce the production cost of the airflow convergence section. Furthermore, PET possesses excellent mechanical properties, exhibiting high rigidity and hardness, and maintains stable mechanical properties at high temperatures, thereby reducing the likelihood of deformation or damage to the airflow convergence section 43.

[0121] In some embodiments, please refer to Figure 1 The aerosol-generated product 100 also includes a coating layer 50.

[0122] The encapsulation layer 50 encapsulates the outer wall of the matrix section 10, the outer wall of the porous structure section 30, at least a portion of the outer wall of the downstream section 40, and at least a portion of the outer wall of the foreplug section 20. This improves the reliability of the connection between the matrix section 10, the downstream section 40, the porous structure section 30, and the foreplug section 20.

[0123] The wrapping layer 50 has a certain degree of hardness, which can protect the matrix section 10 and reduce the surface area of ​​the matrix section 10 directly exposed to the outside world. This reduces the probability of the matrix section 10 becoming damp and deteriorating due to contact with air. At the same time, it helps to reduce the probability of the matrix section 10 coming into contact with other components of the aerosol generation device and causing pollution.

[0124] The specific material of the wrapping layer 50 is not limited, and may be one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene (PE), polyethylene composite fiber paper, and PBAT (Poly(butylene adipate-co-terephthalate)). Specifically, the wrapping layer 50 may be tipping paper or wrapping paper.

[0125] It should be noted that when the wrapping layer 50 covers the entire circumferential outer surface of the filter section 42 or the airflow gathering section 43, the user can directly put the wrapping layer 50 in their mouth to use the aerosol. When the wrapping layer 50 covers part of the circumferential outer surface of the filter section 42 or the airflow gathering section 43, the user can directly put the part of the filter section 42 or the airflow gathering section 43 exposed outside the wrapping layer 50 in their mouth to inhale the aerosol. Of course, the user can also put a mouthpiece on the filter section 42 or the airflow gathering section 43 and inhale the aerosol through the mouthpiece.

[0126] It should be noted that the coating layer 50 can be a single layer, that is, a single coating layer 50 simultaneously encapsulates the matrix segment 10, the foreplug segment 20, the porous structure segment 30, and the downstream segment 40.

[0127] Of course, the coating layer 50 can also be multi-layered. Any segment of the matrix segment 10, the foreplug segment 20, the porous structure segment 30, and the downstream segment 40 can be coated with at least one coating layer 50 to obtain a multi-segment structure; or, at least two segments of the matrix segment 10, the foreplug segment 20, the porous structure segment 30, and the downstream segment 40 can be coated with at least one coating layer 50 to obtain a multi-segment structure, and the multi-segment structure can then be coated with one or more coating layers 50 to obtain the aerosol-generating article 100. For example, please refer to [reference needed]. Figure 1 The encapsulation layer 50 includes a first encapsulation layer 51 and a second encapsulation layer 52. The first encapsulation layer 51 encapsulates the outer wall of the downstream section 40 and part of the outer wall of the matrix section 10. The second encapsulation layer 52 encapsulates the matrix section 10, the porous structure section 30, and the fore plug section 20. The first encapsulation layer 51 and the second encapsulation layer 52 are connected.

[0128] In some embodiments, any two segments of the front plug section 20, porous structure section 30, matrix section 10, support and cooling section 41, filter section 42, and airflow gathering section 43 can be riveted together, connected by physical or chemical adhesives, or connected using a wrapping layer 50. Furthermore, the structure formed using a one-piece molding method can be integrally obtained by co-extrusion, continuous thermoplasticizing, or other methods.

[0129] In some embodiments, please refer to Figure 1 The porous structure segment 30 is formed by integral molding of the prepared slurry through a molding process (e.g., extrusion). The prepared slurry is composed of powders of various raw materials, including at least one of an atomizing agent, a flavoring substance, a harm-reducing and tar-reducing material, and an adsorbent material.

[0130] In related technologies, the heating temperature of heat-not-combustible aerosol-generating products is not high enough, resulting in insufficient release of aroma substances in the matrix segment, thus reducing both the quantity and quality of the aerosol's aroma. Furthermore, the taste of aerosol-generating products is relatively simple because the content of aerosol-generating matrix in the matrix segment is relatively low, leading to insufficient aroma components and a less rich flavor. In addition, aerosol-generating products often have unpleasant aftertastes, potentially leaving unpleasant tastes and sensations such as bitterness and dryness upon heating. This is because heating the matrix segment transfers heat to the pre-stopper segment, causing volatilization, decomposition, and carbonization. The pre-stopper segment, typically made of paper rods or cellulose acetate filter rods, is prone to producing unpleasant tastes and substances.

[0131] In this embodiment, loading the atomizing agent onto the porous structural segment 30 helps to increase the amount of smoke generated when the aerosol generating product 100 is used; loading the flavoring substance (e.g., fragrance or flavoring raw material powder) onto the porous structural segment 30 helps to improve the taste of the aerosol generating product 100 when used; loading the powder of nut shells such as cocoa shells, walnut shells, almond shells, and peanut shells onto the porous structural segment 30 helps to improve the nut and roasted aroma of the aerosol generating product 100 when used; loading the harm-reducing and tar-reducing materials (e.g., molecular sieves, activated carbon, organic acid salts) or adsorbent materials onto the porous structural segment 30 helps to reduce the harmful substances generated when the aerosol generating product 100 is used.

[0132] In some embodiments, please refer to Figure 1 In the axial direction of the aerosol generating article 100, the porous structure segment 30 is arranged adjacent to the matrix segment 10. That is, in the axial direction of the aerosol generating article 100, one end of the porous structure segment 30 is directly connected to one end of the matrix segment 10.

[0133] Since the heating component heats the matrix segment 10, the heat is mainly concentrated on the matrix segment 10. The porous structure segment 30 is directly connected to the matrix segment 10, which helps to increase the heat transferred to the porous structure segment 30, thereby facilitating the release of atomizing agents, fragrance substances, etc. loaded on the porous structure segment 30.

[0134] Furthermore, in some embodiments, please refer to Figure 1 The porous structure segment 30 is disposed between the front plug segment 20 and the matrix segment 10. That is, the porous structure segment 30 is located upstream of the matrix segment 10 and adjacent to the matrix segment 10. This helps to reduce the heat transferred to the front plug segment 20, and helps to improve the volatilization, decomposition, and carbonization of the front plug segment 20, thereby helping to reduce the unpleasant tastes and substances produced by the front plug segment 20, and thus helping to improve the taste of the aerosol.

[0135] In some embodiments, please refer to Figure 1 The matrix section 10 and the filter section 42 are respectively located at the two ends of the supporting cooling section 41 along the axial direction, and the airflow gathering section 43 is located at the end of the filter section 42 away from the supporting cooling section 41.

[0136] In one specific embodiment, from the distal lip end 100b to the proximal lip end 100a of the aerosol generating article 100, the components are sequentially a front plug section 20, a porous structure section 30, a matrix section 10, a support and cooling section 41, a filter section 42, and an airflow gathering section 43.

[0137] In this way, the aerosol flowing out through the airflow gathering section 43 can directly enter the user's mouth. The concentration of the aerosol is best and higher at the location of the outflow gathering section 43. At this point, the user can directly inhale the aerosol, which helps to improve the taste and aroma concentration of the inhaled aerosol.

[0138] In some embodiments, please refer to Figure 1 The length of the aerosol-generated product 100 is 25mm to 100mm. For example, it can be 25mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, etc.

[0139] In some embodiments, please refer to Figure 1 The length of the airflow gathering section 43 accounts for 6% to 20% of the length of the aerosol-generated product 100. For example, it is 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, etc.

[0140] The length dimension of the airflow gathering section 43 refers to its axial dimension in the aerosol generating article 100, and the length dimension of the aerosol generating article 100 refers to its axial dimension.

[0141] In this embodiment, the length of the airflow gathering section 43 is appropriate. On the one hand, the length of the airflow gathering section 43 is not too long, which helps to improve the problem of aerosol accumulation on the airflow gathering section 43, thereby reducing the probability of condensate droplets being generated in the gathering channel 43a and improving the problem of poor taste caused by users sucking up droplets. On the other hand, the airflow gathering section 43 also has a sufficiently long length, which helps to ensure the aerosol gathering effect of the airflow gathering section 43.

[0142] The production process of the airflow gathering section 43 includes, but is not limited to, post-spinning curing, thermoplastic molding, injection molding, casting molding, and extrusion molding.

[0143] In some embodiments, please refer to Figure 1The annular pressure of the airflow gathering section 43 is 180 N / m to 660 N / m. For example, it is 180 N / m, 200 N / m, 220 N / m, 240 N / m, 260 N / m, 280 N / m, 300 N / m, 320 N / m, 340 N / m, 350 N / m, 380 N / m, 400 N / m, 420 N / m, 440 N / m, 460 N / m, 480 N / m, 500 N / m, 520 N / m, 540 N / m, 560 N / m, 580 N / m, 600 N / m, 620 N / m, 640 N / m, 660 N / m, etc.

[0144] In this embodiment, the ring pressure strength of the airflow gathering section 43 is appropriate. On the one hand, the ring pressure strength is not too small, which helps to ensure the structural strength of the airflow gathering section 43 and reduce the probability of its deformation. On the other hand, the ring pressure strength is not too large, and the density does not need to be too large. In this way, it is beneficial to control the production cost of the aerosol generating product 100.

[0145] In some embodiments, please refer to Figure 1 The length of the filter section 42 accounts for 10% to 30% of the length of the aerosol-generating product 100. For example, it is 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, etc.

[0146] The length dimension of the filter section 42 refers to its dimension along the axial direction of the aerosol generating article 100.

[0147] In this embodiment, the length of the filter section 42 is appropriate. On the one hand, the filter section 42 has a sufficient length, which is beneficial to ensuring its filtration effect on aerosols. On the other hand, the length of the filter section 42 is not too long, which helps to improve the problem of reduced aerosol quantity and large suction resistance caused by excessive aerosol interception by the filter section 42.

[0148] The production process of filter section 42 includes, but is not limited to, post-spinning curing, thermoplastic molding, injection molding, casting molding, and extrusion molding.

[0149] It is understandable that the filter section 42 is generally a solid structure. Explaining the "solid structure" using the example of a cylindrical filter section 42, the material used to prepare the filter section 42 must completely fill the cylindrical space. Therefore, there are no significant air passages within the filter section 42, avoiding the traction of airflow caused by significant air passages. However, the filter section 42 has a microporous structure to allow aerosols to pass through, and the airflow can flow relatively evenly through the filter section 42, thus ensuring the aerosol filtration effect. When the filter section 42 adopts a solid structure, its preparation process is preferably spinning followed by curing, extrusion molding, etc.

[0150] In some embodiments, please refer to Figure 1 The ring compression strength of filter section 42 is 270 N / m to 640 N / m. For example, it is 270 N / m, 290 N / m, 310 N / m, 330 N / m, 350 N / m, 370 N / m, 390 N / m, 410 N / m, 430 N / m, 450 N / m, 470 N / m, 490 N / m, 510 N / m, 530 N / m, 550 N / m, 570 N / m, 590 N / m, 610 N / m, 630 N / m, 640 N / m, etc.

[0151] In this embodiment, the ring compression strength of the filter section 42 is appropriate. On the one hand, the ring compression strength is not too small, which helps to ensure the structural strength of the filter section 42 and reduce the probability of its deformation. On the other hand, the ring compression strength is not too large, and the density does not need to be too large. In this way, it is beneficial to control the production cost of the aerosol generating product 100, and at the same time, it is also beneficial for airflow.

[0152] In some embodiments, please refer to Figure 1 The length of the supporting cooling section 41 accounts for 10% to 60% of the length of the aerosol-generated product 100. For example, it is 10%, 11%, 13%, 15%, 17%, 19%, 20%, 22%, 24%, 26%, 28%, 30%, 33%, 36%, 39%, 41%, 43%, 45%, 47%, 49%, 50%, 52%, 54%, 56%, 58%, 60%, etc.

[0153] The length of the cooling section 41 refers to its axial dimension in the aerosol-generating product 100.

[0154] In this embodiment, the length of the supporting cooling section 41 is appropriate. On the one hand, the supporting cooling section 41 has a sufficient length to facilitate the full utilization of its cooling function. On the other hand, the length of the supporting cooling section 41 is not too large, which helps to reduce the probability of a large amount of aerosol condensing and being trapped in the supporting cooling section 41, making it difficult to extract effectively.

[0155] The production process of the supporting cooling section 41 includes, but is not limited to, flat material snap-fit ​​pipe forming, flat material spiral coiling pipe forming, thermoplastic pipe forming, injection molding pipe forming, casting pipe forming, extrusion pipe forming, etc.

[0156] In some embodiments, please refer to Figure 1 The ring compression strength of the supporting cooling section 41 is 380 N / m to 830 N / m. For example, it is 380 N / m, 400 N / m, 420 N / m, 440 N / m, 460 N / m, 480 N / m, 500 N / m, 520 N / m, 540 N / m, 560 N / m, 580 N / m, 600 N / m, 620 N / m, 640 N / m, 660 N / m, 680 N / m, 700 N / m, 720 N / m, 740 N / m, 760 N / m, 780 N / m, 800 N / m, 820 N / m, 830 N / m, etc.

[0157] In this embodiment, the ring compression strength of the supporting cooling section 41 is appropriate. On the one hand, the ring compression strength is not too small, which helps to ensure the structural strength of the supporting cooling section 41 and reduce the probability of its deformation. On the other hand, the ring compression strength is not too large, and the density does not need to be too large. In this way, it is beneficial to control the production cost of the aerosol generating product 100.

[0158] In some embodiments, the length dimension of the matrix segment 10 accounts for 10% to 40% of the length dimension of the aerosol-generated article 100. For example, it is 10%, 12%, 14%, 16%, 18%, 20%, 22%, 24%, 26%, 28%, 30%, etc.

[0159] The length dimension of the matrix segment 10 refers to its dimension along the axial direction of the aerosol-generated article 100.

[0160] In this embodiment, the length of the matrix segment 10 is appropriate. On the one hand, the matrix segment 10 has a sufficiently long length to provide enough effective material for generating aerosols; on the other hand, the length of the matrix segment 10 is not too large, which is conducive to the full release of effective material near the end of the matrix segment 10 close to the front plug segment 20 and to improving the utilization rate of the matrix segment 10.

[0161] The matrix section 10 can have a significant gas path, which facilitates the release of volatile compounds to generate aerosols. The preferred processing technology for the matrix section 10 is an integrated molding process such as extrusion, injection molding, or casting.

[0162] In some embodiments, please refer to Figure 1The ring crush strength of the matrix section 10 is 80 N / m to 400 N / m. For example, it is 80 N / m, 110 N / m, 140 N / m, 170 N / m, 200 N / m, 230 N / m, 260 N / m, 290 N / m, 320 N / m, 350 N / m, 380 N / m, 410 N / m, 440 N / m, 470 N / m, 500 N / m, 530 N / m, 560 N / m, 590 N / m, 620 N / m, 650 N / m, 680 N / m, etc.

[0163] In this embodiment, the ring compression strength of the matrix segment 10 is appropriate. On the one hand, the ring compression strength is not too small, which helps to ensure the structural strength of the matrix segment 10 and reduce the probability of its deformation. On the other hand, the ring compression strength is not too large, and the density does not need to be too large, so as to facilitate the release of volatile compounds in the matrix segment 10.

[0164] In some embodiments, please refer to Figure 1 The length dimension of the porous structure segment 30 accounts for 10% to 30% of the length dimension of the aerosol-generated product 100. For example, it is 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, etc.

[0165] The length dimension of the porous structure segment 30 refers to its dimension along the axial direction of the aerosol-generated product 100.

[0166] In this embodiment, the length of the porous structure segment 30 is appropriate. On the one hand, the porous structure segment 30 has a sufficient length to facilitate the provision of a sufficient amount of functional active substances (such as atomizing agents, fragrance substances, etc.); on the other hand, the length of the porous structure segment 30 is not too large, which is conducive to the full release of the active substances near the distal lip end 100b of the porous structure segment 30, and helps to improve the utilization rate of the porous structure segment 30.

[0167] The porous structure section 30 can provide significant gas passages, thereby facilitating the release of effective substances. The preferred processing technology for the porous structure section 30 is an integrated molding process such as extrusion, injection molding, or casting.

[0168] In some embodiments, please refer to Figure 1The ring compression strength of the porous structure section 30 is 100 N / m to 600 N / m. For example, it is 100 N / m, 125 N / m, 150 N / m, 175 N / m, 200 N / m, 225 N / m, 250 N / m, 275 N / m, 300 N / m, 325 N / m, 350 N / m, 375 N / m, 400 N / m, 425 N / m, 450 N / m, 475 N / m, 500 N / m, 525 N / m, 550 N / m, 575 N / m, 600 N / m, etc.

[0169] In this embodiment, the ring compression strength of the porous structure segment 30 is appropriate. On the one hand, the ring compression strength is not too small, which helps to ensure the structural strength of the porous structure segment 30 and reduce the probability of its deformation. On the other hand, the ring compression strength is not too large, and the density does not need to be too large, so as to facilitate the release of effective substances in the porous structure segment 30.

[0170] In some embodiments, please refer to Figure 1 The length of the front plug section 20 accounts for 5% to 32% of the length of the aerosol-generated product 100. For example, it is 5%, 8%, 11%, 14%, 17%, 20%, 23%, 26%, 29%, 32%, etc.

[0171] The length of the front plug section 20 refers to its axial dimension in the aerosol-generating product 100.

[0172] In this embodiment, the length of the front plug section 20 is appropriate. On the one hand, the front plug section 20 has a sufficient length to facilitate the adsorption of condensate and ensure the cleanliness of the aerosol generating device. On the other hand, the length of the front plug section 20 is not too large, which helps to ensure the air intake of the distal lip end 100b of the aerosol generating product 100 and ensure the amount of aerosol generated.

[0173] The materials used to prepare the front plug section 20 include, but are not limited to, paper, nonwoven fabric, CA, PLA, PET, etc., and the production processes include, but are not limited to, post-spinning curing, thermoplastic molding, and cage molding.

[0174] In some embodiments, please refer to Figure 1 The ring compression strength of the front plug section 20 is 80 N / m to 680 N / m. For example, it is 80 N / m, 110 N / m, 140 N / m, 170 N / m, 200 N / m, 230 N / m, 260 N / m, 290 N / m, 320 N / m, 350 N / m, 380 N / m, 410 N / m, 440 N / m, 470 N / m, 500 N / m, 530 N / m, 560 N / m, 590 N / m, 620 N / m, 650 N / m, 680 N / m, etc.

[0175] In this embodiment, the ring compression strength of the front plug section 20 is appropriate. On the one hand, the ring compression strength is not too small, which helps to ensure the structural strength of the front plug section 20 and reduce the probability of its deformation. On the other hand, the ring compression strength is not too large, and the density does not need to be too large. In this way, it is beneficial to control the production cost of the aerosol generating product 100.

[0176] The aerosol generating article 100 of this application will be further described below with reference to two specific embodiments:

[0177] Example 1:

[0178] Please see Figure 1 The aerosol generating product 100 is a frustum-shaped structure with a diameter of 5.3 mm at the distal lip end 100b and a diameter of 5.4 mm at the proximal lip end 100a.
