AI Technical Summary
In existing heated non-combustible devices, the suction resistance is large when the airflow passes through the solid substrate section. The central heater does not squeeze the substrate evenly when it is inserted and pulled out, which affects the user's suction experience. In addition, residue is easily left behind when the heater is pulled out.
Design an aerosol generation article, wherein the first matrix segment extends along the axial direction and has a non-closed ring cross-section, including a receiving groove and a ventilation groove, to reduce heater insertion friction and reduce suction resistance, while optimizing the airflow path through the notch structure.
It reduces suction resistance during user suction, improves the suction experience, and reduces residue residue when the heater is pulled out, thus improving the performance of the aerosol generation system.

[0001] Cross-reference to related applications
[0002] This application claims priority to Chinese Patent Application No. 202423034535.9, filed on December 9, 2024, entitled "Aerosol Generating Article and Aerosol Generating System", and Chinese Patent Application No. 202422695365.2, filed on November 5, 2024, entitled "Aerosol Generating Article and Aerosol Generating System", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the field of product technology, and in particular to an aerosol generating product and an aerosol generating system. Background Technology
[0004] A heated non-combustible device that releases compounds by heating, rather than burning, an aerosol-forming matrix in an aerosol-generating article. The aerosol-forming matrix can be tobacco or other non-tobacco products, which may or may not contain nicotine.
[0005] In aerosol generating products used in heated non-combustible devices, the matrix section is usually solid. The problems with this are that the airflow passing through the solid matrix section can easily lead to greater suction resistance; the degree of compression of the aerosol forming matrix by the central heater when it is inserted into the matrix section is inconsistent, which can easily affect the user's suction experience; and when the central heater is pulled out of the matrix section, residue can easily remain on the heater.
[0006] Application content
[0007] This application provides an aerosol generating article and an aerosol generating system to reduce the suction resistance of airflow passing through a first matrix section.
[0008] This application provides an aerosol generating article for use with an aerosol generating apparatus, comprising:
[0009] Filter tip section;
[0010] A first matrix segment is arranged on one side of the filter segment along the axial direction of the aerosol-generating article; wherein the first matrix segment is configured to extend along the axial direction and any cross-section of the first matrix segment perpendicular to the axial direction is a non-closed ring with a notch.
[0011] In one example, the first matrix segment has a receiving groove and a venting groove communicating with the receiving groove, the non-closed annular inner periphery defining the boundary of the receiving groove, and the notch defining the boundary of the venting groove.
[0012] In one example, the first matrix segment is a monolithic structure.
[0013] In one example, the first matrix segment is formed by stacking multiple sheet-like matrix fragments along the axial direction.
[0014] In one example, the length of the matrix segment along the axial direction is between 0.5 mm and 2 mm.
[0015] In one example, the number of matrix segments stacked in the first matrix segment is between 6 and 40.
[0016] In one example, the length of the first matrix segment along the axial direction is between 12 mm and 20 mm.
[0017] In one example, the distance of the notch is between 0.1 mm and 0.5 mm.
[0018] In one example, the inner circumference of the non-closed ring is circular, and the diameter of the circle is between 2 mm and 3 mm.
[0019] In one example, the non-closed annular body also has a notch extending from the inner periphery of the non-closed annular body to near the outer periphery of the non-closed annular body.
[0020] In one example, a cooling section is also included, which is disposed between the filter section and the first matrix section along the axial direction.
[0021] In one example, a plug is also included, which is arranged along the axial direction at the end of the first matrix segment away from the filter segment.
[0022] In one example, a second matrix segment is also included;
[0023] The second matrix segment is arranged between the first matrix segment and the filter segment along the axial direction, or the second matrix segment is arranged at the end of the first matrix segment away from the filter segment along the axial direction.
[0024] In one example, the second matrix segment includes at least one of the following:
[0025] The matrix segments are sheet-like and solid;
[0026] The matrix segment has a sheet-like structure and through-pores;
[0027] The matrix segment has a columnar structure and grooves on its sidewalls;
[0028] It is made by rolling one or more sub-substrate segments.
[0029] In one example, an outer wrapping layer is also included, which wraps around the outside of the first matrix segment.
[0030] Another aspect of this application provides an aerosol generation system, including an aerosol generation device and the aforementioned aerosol generation article;
[0031] The aerosol generating device is configured to heat the aerosol forming matrix in the first matrix section to generate aerosols.
[0032] In one example, the aerosol generating apparatus includes a heater configured to be inserted into the inner periphery of the non-closed ring for heating or to heat the aerosol generating article from the bottom.
[0033] The aerosol generating products and aerosol generating systems provided above have a matrix section that extends along the axial direction, and any cross-section of the matrix section perpendicular to the axial direction is a non-closed ring with a notch; in this way, the airflow can pass through the matrix section at least through the notch, reducing the suction resistance when the user inhales and improving the user's inhale experience.

[0052] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.
[0053] As used herein, the terms 'upstream' and 'downstream' are used to describe the relative positions of elements or portions of elements of an aerosol-generating article in relation to the direction in which the user draws the aerosol-generating article during its use.
[0054] Figure 1 is a schematic diagram of an aerosol generation system provided in an embodiment of this application.
[0055] As shown in Figure 1, the aerosol generation system includes an aerosol generation product 100 and an aerosol generation device 200.
[0056] The aerosol generating device 200 includes:
[0057] Chamber 201, in which aerosol-generating article 100 is removably received;
[0058] When the aerosol generating article 100 is received in the chamber 201, the heater 202 can be inserted into the aerosol generating article 100 to heat the extractable material in the aerosol generating article 100 to generate aerosol. The heating method of the heater 202 can be resistance heating, infrared heating, electromagnetic induction heating, etc., and is not specifically limited.
[0059] It should be noted that in other examples, it is also feasible for the heater 202 to be configured to heat at least a portion of the aerosol-generating article 100.
[0060] Cell 203 is used for power supply; cell 203 can be a rechargeable cell or a disposable cell.
[0061] Circuit 204 is used to control the aerosol generating device 200; for example, to control the battery cell 203 to provide power to the heater 202.
[0062] In one example, circuit 204 includes a control unit. The control unit is a hardware component configured to control the overall operation of the aerosol generating apparatus 200. The control unit may include at least one processor. The processor may be implemented as an array of logic gates, or it may be implemented as a combination of a general-purpose microprocessor and memory storing a program executable in the microprocessor. Those skilled in the art will understand that the processor can be implemented in other forms of hardware.
[0063] As shown in Figures 2-7, the aerosol generating article 100 provided in this application has an overall elongated cylindrical structure.
[0064] The appearance of the aerosol generating article 100 can mimic that of a conventional lit and inhalable cigarette. The aerosol generating article 100 can have an outer diameter between approximately 5 mm and 12 mm (e.g., between approximately 6 mm and 8 mm).
[0065] The total length of the aerosol generating article 100 is preferably at least about 35 mm. More preferably, the total length of the aerosol generating article 100 is at least about 40 mm. Even more preferably, the total length of the aerosol generating article 100 is at least about 45 mm. Alternatively, the total length of the aerosol generating article 100 is preferably less than about 80 mm. More preferably, the total length of the aerosol generating article 100 is less than about 75 mm. Even more preferably, the total length of the aerosol generating article 100 is less than about 70 mm.
[0066] In a preferred embodiment, the total length of the aerosol-generating article 100 is about 35 mm to about 80 mm, more preferably about 40 mm to about 75 mm, and even more preferably about 45 mm to about 70 mm.
[0067] The aerosol generating article 100 includes an outer coating layer 101, a filter section 102, a cooling section 103, a first matrix section 104, and a plug 105. The filter section 102, the cooling section 103, the first matrix section 104, and the plug 105 are arranged sequentially along the axial direction of the aerosol generating article 100. Specifically, the filter section 102 is located at the downstream end of the aerosol generating article 100, the first matrix section 104 is arranged along the axial direction on one side of the filter section 102, the cooling section 103 is located along the axial direction between the filter section 102 and the first matrix section 104, and the plug 105 is located at the end of the first matrix section 104 away from the filter section 102, that is, at the upstream end of the aerosol generating article 100.
[0068] The outer wrapping layer 101 wraps around the outside of the filter section 102, the cooling section 103, the first matrix section 104, and the plug 105. The material of the outer wrapping layer 101 includes, but is not limited to, one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, and PBAT.
[0069] The filter section 102 is used to filter aerosols, and the user can hold the filter section 102 in their mouth for inhalation. The material of the filter section 102 includes, but is not limited to, one or more combinations of PE (polyethylene), PLA (polylactic acid), PBAT (butylene adipate-co-terephthalate), PP (polypropylene), cellulose acetate, and cellulose acrylic.
[0070] The cooling section 103 is located immediately upstream of and adjacent to the filter section 102. In use, the aerosol-forming matrix is heated, releasing volatile substances that pass along the cooling section 103 toward the downstream end of the aerosol-generating article 100. These volatile substances are cooled within the cooling section 103 to form an aerosol inhaled by the user. In a preferred embodiment, the cooling section 103 includes a cavity extending along its length. This axially extending cavity ensures that the airflow through the cooling section 103 is longitudinally directed without significant radial deviation. The cooling section 103 can cool the aerosol stream drawn through it by means of heat transfer. The components of the aerosol will interact with the space within the cooling section 103 and lose thermal energy.
[0071] In some embodiments, the temperature of the aerosol stream may decrease by more than 10 degrees Celsius as it is drawn through the cooling section 103. In some embodiments, the temperature of the aerosol stream may decrease by more than 25 degrees Celsius or more than 30 degrees Celsius as it is drawn through the cooling section 103.
[0072] The cooling section 103 and the filter section 102 can be made of the same material or different materials.
[0073] The first matrix segment 104 is disposed immediately upstream of and adjacent to the cooling segment 103. The first matrix segment 104 has an aerosol-forming matrix. The aerosol-forming matrix may include nicotine. A nicotine-containing aerosol-forming matrix may include a nicotine salt matrix. The aerosol-forming matrix may include plant-based material. Preferably, the aerosol-forming matrix includes tobacco-containing material. The aerosol-forming matrix may include homogenized tobacco material, which may be formed by agglomerating particulate tobacco. Alternatively or additionally, the aerosol-forming matrix may include tobacco-free material. The aerosol-forming matrix may include homogenized plant-based material.
[0074] Aerosol forming matrices can include one or more of the following forms: powder, granules, pellets, fragments, filaments, strips, or sheets. Aerosol forming matrices can also contain one or more of the following materials: tobacco leaves, tobacco vein fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco pulp, cast tobacco, and expanded tobacco.
[0075] The aerosol forming matrix may contain at least one aerosol forming agent. An aerosol forming agent is used to describe any suitable known compound or mixture of compounds that promotes aerosol formation in use and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating article. Suitable aerosol forming agents are known in the art and include, but are not limited to: polyols such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecenoate.
[0076] The aerosol forming matrix may include any suitable amount of aerosol forming agent. For example, the content of the aerosol forming agent, on a dry weight basis, may be equal to or greater than 5% of the aerosol forming matrix, and preferably greater than 30% by weight on a dry weight basis. On a dry weight basis, the aerosol forming agent content may be less than about 95%. Preferably, the content of the aerosol forming agent is as high as about 55%.
[0077] The aerosol forming matrix may also contain tobacco or non-tobacco volatile flavoring compounds that are released upon heating of the aerosol forming matrix. The aerosol forming matrix may also contain one or more encapsulations, which may include, for example, additional tobacco or non-tobacco volatile flavoring compounds, and such encapsulations may melt during heating of the aerosol forming matrix.
[0078] Aerosol-forming matrices can be provided on or embedded in a thermally stable carrier. The term "thermally stable" as used herein refers to a material that is substantially non-degradable at temperatures typically heated to which the aerosol-forming matrix is located (e.g., from about 150°C to about 300°C). The carrier can take the form of powder, granules, pellets, fragments, filaments, strips, or sheets. The aerosol-forming matrix can be deposited on the surface of the carrier in the form of, for example, flakes, foams, glues, or pastes. The aerosol-forming matrix can be deposited on the entire surface of the carrier, or alternatively, it can be patterned to provide non-uniform flavor delivery during use.
[0079] In one example, the first matrix segment 104 is configured to extend along the axial direction and any cross-section of the first matrix segment 104 perpendicular to the axial direction is a non-closed loop with a notch.
[0080] Please refer to Figures 5-7 for understanding. In a specific example, the first matrix segment 104 may be formed by stacking multiple sheet-like matrix segments 1041 along the axial direction.
[0081] The matrix segment 1041 is also a non-closed ring with a notch, or any cross-section of the matrix segment 1041 perpendicular to the axial direction is also a non-closed ring with a notch. The length h of the matrix segment 1041 along the axial direction is between 0.5 mm and 2 mm, or between 0.5 mm and 1.5 mm, or 1 mm. The number of matrix segments 1041 stacked in the first matrix segment 104 is between 6 and 40, or between 6 and 30, or between 6 and 20, or between 10 and 20.
[0082] When multiple sheet-like matrix segments 1041 are stacked along the axial direction, in any two adjacent matrix segments 1041, the body 1041a of one matrix segment 1041 remains in contact with the body 1041a of the other matrix segment 1041, and the two can be glued together with an adhesive material; the cavity 1041b in one matrix segment 1041 is aligned with the cavity 1041b in the other matrix segment 1041; the notch 1041c in one matrix segment 1041 is aligned with the notch 1041c in the other matrix segment 1041. Thus, the first matrix segment 104 formed after stacking has a receiving groove A and a venting groove B communicating with the receiving groove A. The non-closed annular inner circumference defines the boundary of the receiving groove A, and the notch defines the boundary of the venting groove. The length H of the first matrix segment 104 formed after stacking along the axial direction can be between 12mm and 20mm, or between 12mm and 18mm, or 16mm.
[0083] When the heater 202 is inserted into the aerosol generating article 100, the heater 202 is inserted into the inner circumference of the non-closed ring, that is, the heater 202 is housed in the receiving groove A; the venting groove B allows for the compression of the aerosol forming matrix. In this way, on the one hand, the frictional force of the heater 202 when inserted into the aerosol generating article 100 is reduced, and when the heater 202 is pulled out of the aerosol generating article 100, the residue remaining on the heater 202 is also reduced; on the other hand, air can flow in through the venting groove B, reducing the suction resistance during user suction and improving the user's suction experience.
[0084] In one example, the distance d of the notch is between 0.1mm and 0.5mm, or between 0.1mm and 0.4mm, or between 0.1mm and 0.3mm. The inner circumference of the non-closed ring is circular, and the diameter of the circle is... Between 2mm and 3mm, for example, the diameter of the circle. It is 2.5mm.
[0085] The plug 105 is located immediately upstream of and adjacent to the first matrix section 104. The plug 105 effectively prevents substances inside the aerosol generating product 100 from falling into the aerosol generating device 200 when the product is inserted. The plug 105 can be made of the same material as the filter section 102, thus blocking the product without affecting the user's suction experience; however, other materials can also be used for the plug 105, which is not limited here.
[0086] Figure 8 is a schematic diagram of another first matrix segment 104 provided in an embodiment of this application. Unlike the examples in Figures 5-7, the first matrix segment 104 is a one-piece structure. For example, it can be formed into a one-piece structure by extrusion molding, injection molding, or compression molding. Extrusion molding refers to a processing method in which a mixture of raw materials is added to an extruder, and the material is heated and plasticized by the action between the extruder barrel and the screw, while being pushed forward by the screw, continuously passing through the die head to form products or semi-finished products of various cross sections. In this way, the aerosol-generated product 100 remains a one-piece medium after being heated and absorbed or after heating stops, and is not prone to disintegration and falling off.
[0087] Figures 9-10 are schematic diagrams of another first matrix segment 104 provided in an embodiment of this application. Unlike the examples in Figures 5-7, the non-closed annular body also has a notch C extending from the inner periphery of the non-closed annular shape to near the outer periphery. The notch C further reduces the frictional force of the heater 202 inserted into the aerosol generating article 100, and also reduces residue remaining on the heater 202 when it is pulled out of the aerosol generating article 100, thus lowering the suction resistance during user suction.
[0088] Figures 11-12 show another aerosol generating article 100 provided in the embodiments of this application.
[0089] Unlike the examples in Figures 2-7, in the examples in Figures 11-12, a second substrate segment 106 is also provided between the cooling segment 103 and the first substrate segment 104, that is, arranged axially between the cooling segment 103 and the first substrate segment 104. The second substrate segment 106 is sheet-like, and its axial length is between 0.5 mm and 2 mm, or between 0.5 mm and 1.5 mm, or 1 mm. In the examples in Figures 11-12, the second substrate segment 106 is solid. In other alternative embodiments, the second substrate segment 106 may have a through-hole penetrating the upper and lower surfaces, and the cross-sectional shape of the through-hole includes, but is not limited to, a circle (e.g., 106a shown in Figure 13), a triangle, a square, etc.
[0090] Unlike the examples in Figures 2-7, the example in Figures 11-12 does not include a plug 105.
[0091] In the examples of Figures 11-12, when the heater 202 is configured to heat the aerosol generating article 100 from the bottom, for example using air heating or light heating, the above-described configuration of the aerosol generating article 100 allows hot air or light to directly heat the second matrix section 106 through the receiving groove A and / or ventilation groove B in the first matrix section 104. This reduces the suction resistance during user suction and, more importantly, reduces the baking area, concentrating the heat for faster smoke emission and shortening the preheating time. Furthermore, it reduces the adsorption of aerosols by the aerosol forming matrix, resulting in a higher aerosol volume in the first few inhalations, avoiding the problem of low aerosol volume in the initial inhalations. Reducing the absorption of aerosol temperature by the aerosol forming matrix also prevents the aerosol temperature from dropping too drastically, thus solving the problem of the aerosol temperature being too low in the first few inhalations.
[0092] It is understandable that the first matrix segment 104 shown in Figures 8-10 is also applicable to the example in Figures 11-12.
[0093] Figures 14-15 show another aerosol generating article 100 provided in the embodiments of this application.
[0094] Unlike the examples in Figures 2-7, in the examples in Figures 14-15, the aerosol generating article 100 has a second matrix section 107 disposed at the end of the first matrix section 104 away from the filter section 102, the second matrix section 107 being disposed immediately upstream of the first matrix section 104 and adjacent to the first matrix section 104.
[0095] In one example, the second matrix segment 107 is columnar, and the sidewall of the second matrix segment 107 has a groove 107a extending from the lower surface to the upper surface of the second matrix segment 107. Through the groove 107a, external air can flow through the gap between the sidewall of the second matrix segment 107 and the outer wrapping layer 101 to the receiving groove A and / or the ventilation groove B.
[0096] In an alternative embodiment, as shown in Figure 16, the second substrate segment 107 is sheet-like, and its axial length is between 0.5 mm and 2 mm, or between 0.5 mm and 1.5 mm, or 1 mm. The second substrate segment 107 may have through-holes penetrating both the upper and lower surfaces, and the cross-sectional shape of the through-holes includes, but is not limited to, circles (e.g., 107a shown in Figure 16), triangles, squares, etc. In other examples, the second substrate segment 107 may be solid.
[0097] In another alternative implementation, as shown in Figure 17, the second matrix segment 107 can be formed by rolling sub-matrix segments 1071 and 1072 together, with the cross-section of the rolled second matrix segment 107 exhibiting a composite spiral shape. Sub-matrix segments 1071 and 1072 can be made of materials of different densities, and different smoking and aroma substances can be added as needed. The tightness of the rolling can also be adjusted as required. It is understood that it is also feasible to use one or more sub-matrix segments for rolling; the rolled shape can be spiral, or other regular or irregular shapes.
[0098] Unlike the examples in Figures 2-7, the example in Figures 14-15 does not include a plug 105.
[0099] In the examples of Figures 14-15, when the heater 202 is configured to heat the aerosol generating article 100 from the bottom, for example using air heating or light heating, the above-described configuration of the aerosol generating article 100 allows hot air or light to directly heat the second matrix section 107. The aerosol generated by heating can flow to the filter section 102 through the receiving groove A and / or ventilation groove B in the first matrix section 104. This reduces the suction resistance during user inhalation and achieves faster smoke output and shorter preheating time. Furthermore, it reduces the adsorption of aerosols by the aerosol forming matrix, resulting in a larger aerosol volume in the first few inhalations, avoiding the problem of low aerosol volume in the first few inhalations. Reducing the absorption of aerosol temperature by the aerosol forming matrix prevents the aerosol temperature from dropping too drastically, thus solving the problem of the aerosol temperature being too cool in the first few inhalations.
[0100] It is understandable that the first matrix segment 104 shown in Figures 8-10 is also applicable to the example in Figures 14-15.
[0101] It is understood that the second matrix segment 106 in the examples of Figures 11-12 can also be constructed as a columnar structure or rolled up from one or more sub-matrix segments. For details, please refer to the second matrix segment 107 in Figures 14 and 17 and their descriptions.
[0102] It should be noted that the second matrix segment 106 or the second matrix segment 107 in the aerosol generating article 100 described above can be regarded as exemplary embodiments of the second matrix segment in different aerosol generating articles. The core function of the second matrix segment is to reduce the suction resistance during user inhalation and improve the user's inhalation experience (including but not limited to increasing the initial contact temperature of the aerosol entering the oral cavity, increasing the initial aerosol generation amount, and enhancing the aerosol flavor, etc.). Therefore, the second matrix segment is not limited to the specific structure described above, and any matrix structure that can achieve the same or similar functions falls within the protection scope of this application.
[0103] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
