Description

Technical Field

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

[0002] Aerosol-generating products can generate aerosols at high temperatures using the principle of heat-non-combustion for user use. Since particulate matter is not easily combined with other functional sections within the aerosol-generating product using a twisting method, aerosol-generating products with built-in granular core materials are more suitable for a filling process. This involves filling the granular core material into a formed thick paper tube as the matrix section. However, the filling process has limitations. The filling method directly results in a low degree of automation in the preparation process, which is not conducive to large-scale, mass production. Furthermore, due to the granular core material morphology, the aroma substances on the surface of the core material are easily volatilized, and the internal aroma is difficult to escape due to the adsorption of aroma-producing substances by micropores. This leads to excessively rapid aroma decay in the aerosol-generating product, ultimately affecting the user experience. Utility Model Content

[0003] This application provides an aerosol-generated article that helps improve production efficiency and solves the problem of excessively rapid aroma decay, thereby improving the user experience.

[0004] This application provides an aerosol generating article, including a matrix segment, the matrix segment including a hot-melt smoke-generating matrix and an air passage tube, the air passage tube and the hot-melt smoke-generating matrix both extending from a first end to a second end of the matrix segment;

[0005] The hot-melt smoke-generating matrix is ​​solid or gel-like at room temperature and can be transformed into a free-flowing liquid after being heated to generate an aerosol.

[0006] The airway tube has a first airway and a second airway. The first airway extends along a first direction, and the second airway extends along a second direction and passes through both ends of the matrix segment. The first airway and the second airway are connected so that the aerosol can enter the second airway through the first airway. The second direction is consistent with the length direction of the matrix segment, and the first direction is perpendicular to the second direction.

[0007] In some optional embodiments, the airway tube is provided with a plurality of exhaust holes, the plurality of exhaust holes penetrating the tube wall along the first direction to form the first airway, and the hot melt smoke-generating matrix is ​​disposed around the outer periphery of the airway tube.

[0008] In some optional embodiments, the airway tube includes an outer tube, an inner tube, and a connecting layer. The interior of the inner tube defines a second receiving space, which is filled with the hot-melt smoke-generating matrix. The first airway penetrates the wall of the inner tube along the first direction. The outer tube is arranged around the outside of the inner tube and spaced apart from the inner tube. The connecting layer is used to connect the outer tube and the inner tube and forms a plurality of second airways between the outer tube and the inner tube.

[0009] In some optional embodiments, the connecting layer includes a plurality of connecting units, which are arranged around the axis of the inner tube on the outer surface of the inner tube; the cross-section of the connecting unit in the radial direction of the inner tube is triangular, rectangular, semi-circular or parabolic.

[0010] In some alternative embodiments, the inner tube is made of a breathable material with micropores, the micropore structure forming the first airway.

[0011] In some alternative embodiments, the matrix segment further includes a housing, the interior of which forms a first receiving space for accommodating the hot-melt smoke-generating matrix and the air passage.

[0012] In some alternative embodiments, the housing includes a splicing paper or a paper tube.

[0013] In some alternative embodiments, the hot-melt smoke-generating matrix comprises smoke-generating particles and a hot-melt matrix encapsulating the smoke-generating particles, the hot-melt matrix comprising one of cocoa butter, carnauba wax, and polyethylene glycol.

[0014] In some optional embodiments, the aerosol generating article further includes a functional section and a blocking section, the functional section being in communication with the second airway, the blocking section being disposed at the end of the matrix section away from the functional section, and at least one of the junctions of the functional section, the blocking section and the matrix section having an air inlet on its outer peripheral surface, the air inlet being used to connect the outside air and the second airway.

[0015] In some alternative embodiments, the blocking section is used to prevent the passage of liquids and gases.

[0016] The aerosol-generating product according to this embodiment includes a matrix segment, which comprises a hot-melt smoke-generating matrix and an air passage. Both the air passage and the hot-melt smoke-generating matrix extend from a first end to a second end of the matrix segment. The air passage has a first air passage and a second air passage. The first air passage extends along a first direction, and the second air passage extends along a second direction, penetrating both ends of the matrix segment. The first and second air passages are connected so that aerosols can flow into the second air passage through the first air passage. Since the hot-melt smoke-generating matrix is ​​solid or gel-like at room temperature, it is easier to mass-produce compared to granular form, and it is also easier to cut and prepare matrix segments for multiple aerosol-generating products, thereby helping to improve production efficiency and reduce production costs. Because the hot-melt smoke-generating matrix can gradually melt after being heated, it can slowly release the aerosols generated inside, greatly improving the problem of the inability to release aroma and the rapid aroma decay inside the granular core material medium, thereby achieving uniform and continuous aerosol overflow. Because the hot-melt smoke-generating matrix can transform into a free-flowing liquid after being heated, the structure of the matrix section collapses, thereby creating space for aerosol flow, which increases the amount of aerosol mist and helps improve the user experience.

Detailed Implementation

[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0037] The aerosol generating article is used in aerosol generating device A and generates an inhalable medium comprising aerosols when the user applies aerosol generating device A for inhalation.

[0038] The term "aerosol" as used herein refers to a dispersion of solid or liquid particles in a gas. As used herein, "aerosol" may also refer to a substance that has been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0039] Please see Figures 1 to 16 The aerosol generating article includes a matrix segment 100, which is used to generate the aforementioned aerosol upon heating. The matrix segment 100 has a first end and a second end disposed opposite to each other along its length. The matrix segment 100 includes a thermomelted smoke-generating matrix 110 and an air passage 120. Both the air passage 120 and the thermomelted smoke-generating matrix 110 extend from the first end to the second end of the matrix segment 100. The thermomelted smoke-generating matrix 110 is solid or gel-like (semi-solid, non-flowing) at room temperature and can be transformed into a free-flowing liquid upon heating to generate an aerosol. The air passage 120 has a first air passage 121 and a second air passage 122. The first air passage 121 extends along a first direction X, and the second air passage 122 extends along a second direction Y and penetrates both ends of the matrix segment. The second air passage 122 and the matrix segment 100 are of equal length. The first air passage 121 and the second air passage 122 are connected so that the aerosol can flow into the second air passage 122 through the first air passage 121.

[0040] Since the hot-melt smoke-generating matrix 110 is solid or gel-like at room temperature, it is easier to mass-produce compared to granular form. It is also easier to cut into matrix segments 100 for preparing multiple aerosol-generating products, thus improving production efficiency and reducing costs. Because the hot-melt smoke-generating matrix 110 gradually melts upon heating, it slowly releases the generated aerosols (or aromas), greatly improving the problem of aroma loss and rapid aroma decay in granular core materials, thus achieving uniform and continuous aerosol release. Furthermore, the hot-melt smoke-generating matrix 110 transforms into a free-flowing liquid upon heating, causing partial structural collapse of the matrix segments 100, creating space for aerosol flow and increasing the aerosol mist volume, thus enhancing the user experience.

[0041] The first airway 121 and the second airway 122 can be straight or curved. To reduce suction resistance during the aspiration process and improve the user's aspiration experience, both the first airway 121 and the second airway 122 are straight, with the second direction Y aligned with the length direction of the matrix segment 100, and the first direction X and the second direction Y perpendicular to each other. Specifically, the first airway 121 extends radially along the matrix segment 100, which shortens the aerosol's movement path and reduces air resistance during aerosol flow, thereby effectively ensuring the stability, continuity, and smoothness of the aerosol. Similarly, the second airway 122 extends axially along the matrix segment 100, which also shortens the movement path and reduces air resistance.

[0042] Please see Figures 2 to 4 In some embodiments, the airway tube 120 is provided with a plurality of exhaust holes 123, which penetrate the tube wall of the airway tube 121 along the first direction X to form a first airway 121.

[0043] In some embodiments, a plurality of exhaust holes 1231 are evenly arranged around the circumference of the airway tube 120 to form an exhaust hole row. The exhaust hole row is evenly arranged along the axial direction of the airway tube 120 and is arranged from one end of the airway tube 120 to the other end, thereby forming a first airway 121 with a uniform distribution and a large coverage area on the airway tube 120, so that the aerosol can be discharged into the second airway 122 along the minimum path, which helps to increase the amount of aerosol mist.

[0044] In some embodiments, the matrix segment 100 may further include a housing 124, the interior of which forms a first receiving space 1241. The first receiving space 1241 is used to receive the hot-melt smoke-generating matrix 110 and the airway tube 120, and the hot-melt smoke-generating matrix 110 is disposed around the outer periphery of the airway tube 120. The housing 124 can encapsulate the hot-melt smoke-generating matrix 110 and the airway tube 120 into an integral structure. When the user inhales, the hot-melt smoke-generating matrix 110 is heated to generate an aerosol. The aerosol enters the second airway 122 from the outside to the inside (from the housing 124 to the airway tube 120) along the first airway 121, and flows along the second airway 122 under the action of suction. The flow direction of the aerosol is as follows: Figure 4 As shown in the right figure.

[0045] In some embodiments, the outer shell 124 comprises molded paper or a thick paper tube. When preparing the matrix segment 100, the air passage tube 120 and the hot-melt smoke-generating matrix 110 can be compositely connected, then wrapped with molded paper to form a slender structure, and then cut into 10mm-14mm sections to obtain a hollow matrix segment 100. For example, since the matrix segment 100 has a columnar structure rather than granules, the hot-melt smoke-generating matrix can be integrated into the outer shell 124 by a twist-joint composite method, and can be connected with other structures shown in the figure by a twist-joint composite method. Therefore, the outer shell 124 can be molded paper rather than a thick paper tube. In this way, when using a circumferentially heated aerosol generating device A, the heat generated by the heating component of the aerosol generating device A is transferred from the periphery to the center to heat the aerosol generating product (especially the matrix segment 100). The heat is more easily transferred into the matrix segment 100, avoiding the problem of heat not being able to be transferred due to the thick paper tube as the outer shell 124, and the defect of paper impurities generated when baking the thick paper tube. In other embodiments, the housing 124 includes a thick paper tube into which the matrix segment 100 can be inserted from the end, resulting in a greater assembly efficiency than granule filling, and the paper tube thickness is greater than 1 mm.

[0046] It should be noted that the hollow matrix section 100 mentioned above is named based on its exhaust method. Since the aerosol-generated product exhausts the aerosol through the second air passage 122, in this structure, the second air passage 122 is located in the middle of the entire matrix section 100 and in the middle of the hot-melt smoke-generating matrix 110, hence the name hollow.

[0047] In some embodiments, the airway tube 120 is a hollow tube made of silicone material with at least one open end. For example, the airway tube 120 has an opening for discharging aerosols. Alternatively, the airway tube 120 may be open at both ends, with one end for discharging aerosols and the other end for allowing outside air to enter, so that the air carries the aerosols to the user's mouth (or nose).

[0048] Please see Figures 5 to 10In some embodiments, the airway 120 includes an outer tube 125, an inner tube 126, and a connecting layer 127. The inner tube 126 defines a second receiving space 1261, which is filled with a hot-melt smoke-generating matrix 110. A first airway 121 penetrates the wall of the inner tube 126 along a first direction X. The outer tube 125 is arranged around the outside of the inner tube 126 and spaced apart from it. The connecting layer 127 connects the outer tube 125 and the inner tube 126, forming a plurality of second airways 122 between the outer tube 125 and the inner tube 126. The first airways 121 can connect the inside and outside of the inner tube 126, allowing the aerosol generated by the heated hot-melt smoke-generating matrix 110 to be discharged from the inside to the second airways 122. The flow direction of the aerosol is as follows: Figure 6 As shown in the right figure, the connection layer 127 can improve the stability of the airway tube 120 and also form a uniform second airway 122, so that the aerosol is evenly distributed around the circumference of the inner tube 126.

[0049] Please continue reading. Figures 8 to 10 In some embodiments, the connecting layer 127 includes a plurality of connecting units 1271, which are arranged around the axis of the inner tube 126 on the outer surface of the inner tube 126. Specifically, the plurality of connecting units 1271 can be arranged continuously and end to end, or they can be arranged at intervals to evenly divide the interval between the outer tube 125 and the inner tube 126.

[0050] In some embodiments, the outer tube 125, inner tube 126, and connecting layer 127 form a corrugated tube structure, which not only provides a second air passage 122 around the inner tube 126 for aerosol passage, but also improves the buffering and pressure resistance of the aerosol-generated product, thereby extending its service life. The outer tube 125, inner tube 126, and connecting layer 127 can be an integrally formed structure, used to wrap the formed hot-melt smoke-generating matrix 110 during the preparation of the matrix segment 100, and finally cut into 10mm-14mm sections to obtain a four-sided matrix segment 100.

[0051] It should be noted that the four-sided matrix section 100 mentioned above is named based on its exhaust method. Since the aerosol-generated product exhausts the aerosol through the second air passage 122, in this structure, the second air passage 122 is located at the outer part of the entire matrix section 100 and is located around the hot melt smoke matrix 110, hence the name four-sided.

[0052] In some embodiments, the cross-section of the connecting unit 1271 in the radial direction of the inner tube 126 is triangular (e.g., Figure 8 As shown), semi-circular (as shown) Figure 9 As shown), rectangle (as shown) Figure 10 (as shown) or parabolic.

[0053] In some embodiments, the inner tube 126 is made of a breathable material with micropores, which forms the first air passage 121. Specifically, the inner tube 126 can be made of highly breathable molded paper or molded film. This structural design can prevent the hot-melt smoke-generating matrix 110 from blocking the first air passage 121 when it flows freely after being heated, thereby improving the aerosol throughput and effectively ensuring the amount of aerosol mist.

[0054] In some embodiments, the hot-melt smoke-generating matrix 110 includes an aerosol-generating matrix and a hot-melt matrix encapsulating the aerosol-generating matrix, wherein the hot-melt matrix includes at least one of cocoa butter, carnauba wax, and polyethylene glycol (PEG).

[0055] In some embodiments, the aerosol generating matrix can be made of at least one powdered or granular material capable of generating aerosols upon heating. When mixed with a hot-melt matrix, it can form a solid or gel state, reducing the difficulty of composite molding with the airway tube 120. To further facilitate the mixing and molding of the aerosol generating matrix and the hot-melt matrix, purified water and an adhesive can be added during the preparation of the hot-melt smoke-generating matrix 110. During preparation, the aerosol generating matrix, the hot-melt matrix, purified water, and the adhesive are mixed, sheared, and stirred in a container. The mixture is then poured into a mold in a hot-melt state, followed by demolding and slitting. The resulting material has a uniform and stable composition. The aerosol generating matrix includes tobacco particles or non-tobacco plant particles, such as cloves, star anise, and fennel.

[0056] In some embodiments, the adhesive includes at least one of gelatin, carrageenan, xanthan gum, guar gum, locust bean gum, tamarind polysaccharide, povidone K30, and povidone K90, and the use of the adhesive can improve the stability of the hot melt fumigation matrix 110.

[0057] It should be further explained that, in the preparation of the hot-melt smoke-generating matrix 110, the aerosol generating matrix, the hot-melt matrix, the purified water and the adhesive are only physically mixed in the container. The adhesive and purified water are only used to bond the hot-melt matrix and the aerosol generating matrix into an integrated structure. The aerosol generating matrix mainly generates aerosols, while the hot-melt matrix utilizes its morphological characteristics before and after heating to make the matrix segment 100 morphologically stable at room temperature, and provides space for aerosols to pass through after free flow after heating.

[0058] Please see Figures 11 to 16The aerosol generating product also includes a functional section 200 and a blocking section 300. The functional section 200 is connected to the second air passage 122. The blocking section 300 is located at the end of the matrix section 100 away from the functional section 200. At least one of the junctions of the functional section 200, the blocking section 300, and the matrix section 100 has an air inlet 400 on its outer peripheral surface. The air inlet 400 is used to connect to outside air and the second air passage 122, allowing outside air to enter from the side of the aerosol generating product. The aerosol generating device A does not need to have an air inlet structure. The functional section 200 is the proximal end of the aerosol generating product (the end closer to the user), through which the user completes the suction action. The blocking section 300 is the distal end of the aerosol generating product (the end farther from the user), used to block and protect the matrix section 100. For example, as... Figures 13 to 15 As shown, an air inlet 400 is provided at the junction of the matrix section 100 and the sealing section 300. Outside cold air enters the second air passage 122 from the bottom of the matrix section 100, carrying the aerosol within the second air passage 122 to the functional section 200. For example, as... Figure 16 As shown, an air inlet 400 is provided at the junction of the functional section 200 and the matrix section 100. Cold air enters from the top of the matrix section 100 (the side of the matrix section 100 closest to the functional section 200 is defined as the top, and the side furthest away is defined as the bottom, based on the usage state). The aerosol collected in the second air passage 122 flows upward and mixes with it.

[0059] In practical applications, when the airway tube 120 is a hollow silicone tube and an air inlet 400 is provided at the junction of the matrix section 100 and the sealing section 300, when the user draws air in, the outside cold air enters from the bottom of the matrix section 100 along the second airway 122 inside the airway tube 120. The aerosol generated by the heated hot-melt smoke-generating matrix 110 overflows laterally inward into the airway tube 120 and is collected in the second airway 122 inside the airway tube 120 under negative pressure and mixes with the cold air.

[0060] When the airway tube 120 has a corrugated structure and an air inlet 400 is provided at the junction of the matrix section 100 and the sealing section 300, cold air from the outside flows in from the bottom of the corrugated structure, that is, from the bottom between the inner tube 126 and the outer tube 125 into the second airway 122. The aerosol generated by the heated hot-melt smoke-generating matrix 110 overflows laterally outward into the second airway 122 between the inner tube 126 and the outer tube 125, and is collected in the second airway 122 under negative pressure and mixed with the cold air.

[0061] When an air inlet 400 is provided at the junction of the functional section 200 and the matrix section 100, the second air passage 122 is connected to the functional section 200. Outside cold air enters through the air inlet 400. When the user draws air, negative pressure is generated inside. Aerosol overflows from the first air passage 121 and is automatically collected into the second air passage 122, where it mixes with the cold air.

[0062] In some embodiments, multiple air inlets 400 are provided and uniformly arranged around the axis of the aerosol-generating article, allowing air to enter the second air passage 122 uniformly. The air inlets 400 extend along a first direction X (or the radial direction of the matrix segment 100), and their axis is a straight line along this direction. This can reduce air resistance during air entry, accelerate the aerosol discharge speed, and ensure smooth aerosol discharge. The air inlets 400 can be formed by methods including but not limited to laser drilling. The radial cross-section of the air inlets 400 can be rectangular, circular, triangular, polygonal, or other irregular structures.

[0063] Please continue reading. Figure 12 In some embodiments, functional segment 200 includes a hollow portion 210 and a filter portion 220. The hollow portion 210 is disposed between the filter portion 220 and the matrix segment 100. The hollow portion 210, due to its internal hollow structure, allows aerosols to pass through, thereby guiding the aerosols generated by the matrix segment 100 to the filter portion 220. The filter portion 220 filters the aerosols, resulting in purer aerosols flowing into the user's mouth (or nose) and improving their taste. The filter portion 220 is made of a fibrous material (such as filter cotton) with filtering properties.

[0064] Please continue reading. Figure 12 In some embodiments, the hollow section 210 includes a continuously arranged airflow unit 211 and a cooling unit 212. The airflow unit 211 is disposed near the matrix section 100, and the cooling unit 212 is disposed near the filter section 220. The cooling unit 212 can reduce the temperature of the aerosol and prevent burns to the user.

[0065] In some embodiments, the air inlet 400 mentioned above can also be provided on the cooling unit 212. The air inlet 400 connects the second air passage 122 and the outside air. After the outside air is mixed with the aerosol, it flows to the user's mouth (or nose) under the action of suction based on the Bernoulli principle.

[0066] In some embodiments, the matrix segment 100, functional segment 200, and sealing segment 300 are joined together by a twisting process. Specifically, since the functional segment 200 may include a filter section 220 and a hollow section 210, during the twisting process, the matrix segment 100, hollow section 210, and sealing segment 300 can be joined together first, followed by the joining of the filter section 220. Of course, other twisting sequences can also be used. For example, the matrix segment 100, hollow section 210, sealing segment 300, and filter section 220 can be joined together simultaneously, or the matrix segment 100 and hollow section 210 can be joined together first, followed by the joining of the matrix segment 100 and sealing segment 300, and then the joining of the hollow section 210 and filter section 220. Compared to the injection method, the twisting process is simpler and more efficient, and the process is mature. The hot-melt smoke-generating matrix 110, which is solid or gel-like at room temperature, facilitates the implementation of the twisting process, thereby improving production efficiency.

[0067] In some embodiments, the blocking section 300 is used to prevent liquid and gas from passing through, so that the blocking section 300 neither allows air to enter nor leaks condensate, thereby preventing condensate from entering the aerosol generating device A and helping to achieve a cleaning-free aerosol generating device A.

[0068] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
