[0012] In one embodiment, the monomers on a single trajectory line are arranged in a straight line along the first direction, and a plurality of trajectory lines are arranged in a straight line along the second direction, and the first direction and the second direction intersect.

[0013] In one embodiment, the monomers are distributed in an array, the number of the monomers in the first direction is the same as the number of the monomers in the second direction, the monomers on a single trajectory line are equidistant, and the spacing between the trajectory lines is equal.

[0014] In one embodiment, the monomers on a single trajectory are arranged along a circumferential direction around the center of the aerosol generating substrate, and a plurality of trajectory lines are arranged in concentric circles along the radial direction of the aerosol generating substrate.

[0015] In one embodiment, the aerosol generating substrate is composed of a plurality of the monomers connected together, and in a plane perpendicular to the length direction of the aerosol generating substrate, the cross-sectional shape of the aerosol generating substrate is in the shape of a straight line, a polygon, a circle, or an ellipse.

[0016] In one embodiment, the first air channel runs through at least one end of the monomer along the length direction, and the first air channel is a straight air channel, or the first air channel is in a spiral shape consistent with the monomer.

[0017] In one embodiment, the peripheral side wall of the single body defines a second air channel.

[0021] In one embodiment, there are multiple monomers, and the materials of the monomers are different.

[0022] In one embodiment, the first air channel runs through both ends of the monomer along the length direction, and the first air channel is spiral or linear.

[0023] A second aspect of an embodiment of the present application provides an aerosol generating article, comprising:

[0025] A functional segment, which is arranged at one end of the aerosol generating substrate along the length direction and at least includes a filtering segment for filtering aerosol;

[0043] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0044] In the description of this application, the orientation or position relationship of "length direction", "first direction" and "second direction" is based on the attached Figure 1 , Attachment Figure 5 To Attachment Fig.10 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0045] The present application embodiment provides an aerosol generating product, please refer to Figures 1 to 11 The aerosol-generating article 1 comprises an aerosol-generating substrate 11 and a functional segment 12 .

[0046] See also Figure 10 to Figure 11 The functional segment 12 is arranged at one end of the aerosol generating substrate 11 along the length direction, and the functional segment 12 at least includes a filtering segment 122 for filtering aerosol.

[0047] The functional segment 12 is arranged at one end of the aerosol generating matrix 11 along the length direction, that is, the aerosol generating matrix 11 and the functional segment 12 are respectively located at the two ends of the aerosol generating product 1, wherein the aerosol generating matrix 11 is the far lip end of the aerosol generating product 1, and the functional segment 12 is the near lip end of the aerosol generating product 1.

[0048] The proximal lip end refers to the end of the aerosol generating article 1 that is close to the user when the user is using the aerosol generating article 1 , and the distal lip end refers to the end of the aerosol generating article 1 that is away from the user when the user is using the aerosol generating article 1 .

[0049] The functional section 12 comprises at least a filter section 122 for filtering aerosols.

[0050] It should be noted that the filter section 122 is used to filter the aerosol. It is understandable that since the aerosol flows through the filter section 122, the filter section 122 also has the function of further cooling the aerosol.

[0051] The functional section 12 may further include a cooling section 121 which can be used to cool the aerosol.

[0052] See also Figure 10 to Figure 11 The cooling section 121 can be arranged between the aerosol generating matrix 11 and the filtering section 122 .

[0053] Of course, the functional segment 12 may also have the functions of supporting and / or filtering and / or adjusting the suction resistance.

[0054] The aerosol-generating article 1 relies on the aerosol-generating substrate 11 to generate aerosol, and the functional section 12 is not used to generate aerosol.

[0055] In some embodiments, see Figures 9 and 10 The aerosol generating product 1 further comprises a wrapping layer 13, which wraps around the outer peripheral side of the functional segment 12 and the aerosol generating substrate 11. The wrapping layer 13 provides installation space and protection for the aerosol generating substrate 11 and the functional segment 12, reduces the probability of damage to the aerosol generating substrate 11 and the functional segment 12, and increases the reliability of the aerosol generating product 1.

[0056] Among them, the wrapping layer 13 wrapped around the outer peripheral side of the aerosol generating matrix 11 and the functional segment 12 can be the wrapping layer 13 wrapped around the entire outer peripheral side of the aerosol generating matrix 11 and the functional segment 12, or the wrapping layer 13 wrapped around part of the outer peripheral side of the aerosol generating matrix 11 and the functional segment 12.

[0057] It is understandable that the material of the wrapping layer 13 has a certain structural strength to reduce the probability of deformation of the aerosol generating article 1 due to airflow pressure during use.

[0058] The specific material of the wrapping layer 13 is not limited, such as one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly (butyleneadipate-co-terephthalate, poly (butylene adipate-co-terephthalate)) and the like.

[0059] It should be noted that, when the wrapping layer 13 wraps the entire outer circumference of the functional segment 12, the user can directly hold the wrapping layer 13 in the mouth to inhale the aerosol; when the wrapping layer 13 wraps part of the outer circumference of the functional segment 12, the user can directly hold the part of the functional segment 12 extending beyond the wrapping layer 13 in the mouth to inhale the aerosol. Of course, the user can also provide a nozzle outside the functional segment 12 to inhale the aerosol through the nozzle.

[0060] The wrapping layer 13 is not limited to one layer. For example, during the manufacturing process, each section such as the aerosol generating matrix 11, the cooling section 121 and the filtering section 122 can be first wrapped by a wrapping layer 13, and then wrapped as a whole outside the wrapping layer 13 of each section by another wrapping layer 13.

[0061] An embodiment of the present application further provides an aerosol generating system, including an aerosol generating device and a sol generating product provided in an embodiment of the present application, wherein the aerosol generating device includes a heating element (not shown), which is used to heat the monomer 111 to generate an aerosol.

[0062] Specifically, the aerosol generating device includes a shell and a power supply assembly arranged in the shell. The shell has a storage chamber. The power output part of the power supply assembly is arranged in the storage chamber or around the side wall of the storage chamber. When the aerosol generating product 1 is inserted into the storage chamber at a position corresponding to the length direction range of the monomer 111, the power output part transmits power to the heating element in a contact or non-contact manner. The heating element receives energy from the outside and generates heat, thereby heating the monomer 111 and generating an aerosol.

[0063] In the embodiment of the present application, the length direction does not specifically refer to the direction in which the outer contour of the monomer 111 is the longest. Specifically, the direction in which the aerosol generating product 1 is inserted into the storage bin and the direction in which the aerosol generating product 1 is taken out of the storage bin are both parallel to the length direction. The length of the monomer 111 along the length direction may be longer, shorter, or the same as the length in other directions.

[0064] For example, when the appearance of the monomer 111 is cylindrical, the length direction is the axial direction of the monomer 111. It should be noted that even if the axial length of the monomer 111 is less than its diameter, the length direction of the monomer 111 is still the axial direction. For another example, when the appearance of the monomer 111 is a rectangular parallelepiped, the length direction is still the direction defined above, that is, the direction in which the aerosol generating product 1 is taken out of the containing chamber, and the length direction of the monomer 111 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0065] The present application embodiment provides an aerosol generating matrix, please refer to Figures 1 to 8 The aerosol generating substrate 11 includes at least one monomer 111. The monomer 111 has at least one first air channel 111a inside, and the first air channel 111a runs through at least one end of the monomer 111 along the length direction. The aerosol generating substrate 11 is spirally formed by at least one monomer 111, or the aerosol generating substrate 11 is formed by connecting a plurality of monomers 111.

[0066] It should be noted that the aerosol generating product 1 of the embodiment of the present application can be used for inhalation by ignition or by heating without burning. In the embodiment of the present application, the aerosol generating product 1 is used for inhalation by heating without burning as an example.

[0067] The aerosol generating article 1 is used in conjunction with an aerosol generating device.

[0068] The monomer 111 is used to generate aerosol when heated for users to inhale.

[0069] In the embodiment of the present application, the monomer 111 is substantially cylindrical, which may be a cylindrical shape (i.e., a circular cross-sectional shape), a prism shape (i.e., a polygonal cross-sectional shape), an elliptical cylinder shape (i.e., an elliptical cross-sectional shape), or other regular or irregular shapes, etc., without limitation herein.

[0070] The monomer 111 is an integrated structure, for example, an integrated structure can be formed by extrusion, injection molding or die-casting. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the mold of the extruder outlet to form various cross-section products or semi-finished products. In this way, after the monomer 111 is heated and sucked or stops being heated, it is an integrated medium, and it is not easy to disintegrate and fall off, which solves the problems of the thin sheet, filamentous component, granular component falling off, and difficulty in cleaning in the prior art of the thin sheet, filamentous component or loose particle monomer 111, as well as the problem of uneven components.

[0071] The monomer 111 has at least one first air channel 111a inside. Figures 1 to 8 The first air channel 111 a passes through at least one end of the monomer 111 along the length direction.

[0072] The monomer 111 has at least one first air channel 111 a inside. The monomer 111 may have one first air channel 111 a inside, or the monomer 111 may have a plurality of first air channels 111 a inside.

[0073] It should be noted that the “multiple” mentioned in the embodiments of the present application refers to a number of two or more.

[0074] In some embodiments, the first air channel 111 a passes through the same end of the monomer 111 along the length direction, and the other end is closed.

[0075] In some other embodiments, a portion of the first air passage 111 a passes through one end of the monomer 111 along the length direction, and another portion of the first air passage 111 a passes through the other end of the monomer 111 along the length direction.

[0076] In some other embodiments, please refer to Figures 1 to 8 Each first air channel 111a passes through both ends of the monomer 111 along the length direction, that is, the first air channel 111a extends along the length direction of the monomer 111, and the air flow can flow from one end of the monomer 111 through the first air channel 111a to the other end of the monomer 111. Preferably, the first air channel 111a is parallel to the central axis of the monomer 111.

[0077] The pore wall of the first air channel 111a constitutes the inner surface of the monomer 111. The first air channel 111a can increase the inner surface area of ​​the monomer 111, facilitate heat transfer, and improve heating efficiency. In addition, the monomer 111 generates an aerosol after heating, and the aerosol is collected in the first air channel 111a and transported to the suction end under the action of the suction negative pressure. The first air channel 111a can reduce the suction resistance of the user and improve the user experience. It should be noted that the suction resistance is positively correlated with the flow resistance of the aerosol. The smaller the flow resistance of the aerosol in the monomer 111, the smaller the suction resistance experienced by the user. The greater the flow resistance of the aerosol in the monomer 111, the greater the suction resistance experienced by the user.

[0078] It should be noted that the shape of the first air channel 111a is not limited here. For example, on a plane perpendicular to the length direction of the monomer 111, the cross-sectional shape of the first air channel 111a includes but is not limited to a circle (such as Figure 5 and Figure 8 ), elliptical, racetrack or polygonal, wherein the polygon includes regular or irregular polygons.

[0079] Among them, the runway shape refers to: a shape similar to an athletics track, composed of two semicircles and two parallel straight edges alternately connected.

[0080] The cross-sectional shape of the first air channel 111 a refers to the cross-sectional shape of the first air channel 111 a cut along a plane perpendicular to the length direction of the monomer 111 .

[0081] In addition, the cross-sectional shapes of the first air channels 111a may be exactly the same, or the cross-sectional shapes of at least two of the first air channels 111a may be different. For example, the cross-sectional shape of at least one of the first air channels 111a may be circular, and the cross-sectional shape of at least one of the first air channels 111a may be polygonal.

[0082] It should be noted that the monomer 111 is formed with micropores, and the micropores are connected to each other to form a micro-airway connected to the first airway 111a. In other words, the micro-airway is connected to the first airway 111a, and since the micro-airway is formed by the connection between the micropores, the micropores are connected to the micro-airway. In addition, it can be understood that the connection between the micropores can be that some of the micropores are connected and some of the micropores are not connected; or all the micropores can be connected to each other. For example, in an embodiment where the monomer 111 is a particle combination, the gaps between the particles constitute the micropores.

[0083] It should be noted that the above-mentioned first airway 111a belongs to a hole in the macroscopic sense, and the micropore belongs to a hole in the microscopic sense. The cross-sectional area of ​​the first airway 111a is much larger than the cross-sectional area of ​​the micropore. Exemplarily, the cross-sectional area of ​​the first airway 111a is at least 20 times the cross-sectional area of ​​the micropore. When the size of the micropore remains roughly unchanged, when it is less than 20 times, the size of the first airway 111a will be too small, and the aerosol will not be easily released from the inner wall of the first airway 111a into the first airway 111a, and the user's suction resistance will be large, and the user's suction experience will decrease. Therefore, in this embodiment, when the cross-sectional area of ​​the first airway 111a is greater than or equal to 20 times the cross-sectional area of ​​the micropore, the rate at which the aerosol is released from the inner wall of the first airway 111a can be guaranteed, and the suction resistance can also be reduced, thereby improving the user's suction experience.

[0084] The first air channel 111a and the micro air channel can increase the surface area of ​​the monomer 111, facilitate heat transfer, and improve heating efficiency. The medium of the monomer 111 releases aerosol when heated, and is collected in the first air channel 111a through the gaps between the wall materials or the micro air channels. The aerosol released by the atomized medium exposed to the first air channel 111a (i.e., the atomized medium located on the inner wall surface of the first air channel 111a) can be directly released to the first air channel 111a. The aerosol between adjacent first air channels 111a can also circulate with each other through the micro air channels and be transported to the suction end under the action of the suction negative pressure.

[0085] The embodiment of the present application provides an aerosol generating matrix 11, and the aerosol generating matrix 11 includes at least one monomer 111. The inside of the monomer 111 has a first air channel 111a, and the first air channel 111a runs through at least one end of the monomer 111 along the length direction. The aerosol generating matrix 11 is spirally formed by at least one monomer 111, or the aerosol generating matrix 11 is formed by connecting multiple monomers 111. By providing at least one first air channel 111a inside the monomer 111, the pore wall of the first air channel 111a constitutes the inner surface of the monomer 111, and the first air channel 111a can increase the inner surface area of ​​the monomer 111, facilitate heat transfer, and improve heating efficiency. The monomer 111 is heated to generate an aerosol, and the aerosol is collected in the first air channel 111a and transported to the suction end under the action of the suction negative pressure. The first air channel 111a can reduce the suction resistance of the user's suction, and the amount of smoke is large, which improves the stability of aerosol release and suction. In addition, the monomer 111 may be an integrated structure, for example, an integrated structure may be formed by extrusion, die casting or injection molding to improve the uniformity of the density of the monomer 111 and further improve the stability of aerosol release and suction.

[0086] The aerosol generating matrix 11 can be spirally formed by at least one monomer 111. The spiral aerosol generating matrix 11 can increase the flow speed of the aerosol along the outer side wall of the aerosol generating matrix 11, thereby improving the aerosol extraction efficiency and further improving the user experience. Furthermore, the aerosol generating matrix 11 can also be composed of a plurality of monomers 111 connected together, which can increase the flow speed of the aerosol of the plurality of monomers 111 along the outer side wall of the connection of the aerosol generating matrix 11, or can increase the flow speed of the aerosol along the outer side wall of the connection of the plurality of monomers 111. In addition, when a monomer 111 reaches the release temperature and is released, the next monomer 111 is gradually heated, and each monomer 111 releases aerosol respectively, reducing the influence of the releasing monomer 111 on the unreleased monomer 111, which is equivalent to that the monomer 111 releasing the aerosol after a period of time is fresh, thereby achieving the layer-by-layer release of a specific flavor of the aerosol or the layer-by-layer release of a single flavor, making the aerosol flavor adjustable or the aerosol purer, that is, reducing the influence of the first heated monomer 111 on the aerosol release of the subsequent heated monomer 111, which is beneficial to improving the consistency of smoking.

[0087] In the related art, the smoking materials of smoking products are, for example, granular, shredded tobacco, thin sheets, etc., which are formed by integral filling, rolling or gathering. When shredded tobacco smoking products are matched with a central heat source, the central material of the smoking products tends to move upward, resulting in "shred blocking". Granular smoking products are prone to poor uniformity of filling particle shape during production and processing, and the seals are prone to fall off, moisture absorption, and sticking and agglomeration with utensils during use.

[0088] The monomer 111 provided in the embodiment of the present application is an integrated structure, which improves the uniformity of the density of the aerosol generating matrix 11 and improves the stability of aerosol release and suction. In addition, the mass of the monomer 111 with an integrated structure is relatively uniform. When the heating element heats the monomer 111, it will not squeeze the structure around the monomer 111, so that the monomer 111 maintains a relatively uniform matrix density. Furthermore, the monomer 111 with an integrated structure is not easy to stick to the aerosol generating device, agglomerate, etc.

[0089] In some embodiments, the monomer 111 includes plant materials, and the plant materials are in the form of flakes, strips or powders. The plant materials are used to generate aerosols when heated. The plant materials are the core source of fragrance. The endogenous substances in the plant materials can give users a sense of physiological satisfaction. Endogenous substances such as alkaloids enter the human blood and promote the pituitary gland to produce dopamine, thereby obtaining a sense of physiological satisfaction. The flakes, strips or powders are all shapes formed after the plant materials are crushed.

[0090] Exemplarily, in one embodiment, the plant material can be a combination of one or more substances such as tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco dust and aromatic plants after being crushed.

[0091] The sheet shape is a shape formed by destroying the original shape of the plant material. For example, the plant material is formed by rolling, thickening or papermaking. For example, the sheet shape is formed by making the plant material into fiber pulp and then drying and dehydrating it.

[0092] Strips are the shape formed by directly cutting plant materials.

[0093] Powdered form refers to the shape of plant materials after grinding.

[0094] Plant raw materials refer to raw materials that retain the natural form of plants. Generally, after plant raw materials are harvested from the land, they are processed by removing rotten old leaves, cleaning, drying, etc., but no deep processing that changes the natural form of the plants is carried out.

[0095] The material of the monomer 111 includes components and the ratio of each component.

[0096] In some embodiments, see Figures 2 to 8 The number of monomers 111 is multiple, and the materials of the monomers 111 are the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the consistency of the taste of the aerosol, thereby improving the consistency of the suction.

[0097] In some embodiments, see Figures 2 to 8 , there are multiple monomers 111, and each monomer 111 is made of a different material. By setting the materials of each monomer 111 to be different, the aerosols generated by monomers 111 of different materials have different flavors, so that a combination of different flavors can be achieved. By setting the materials of each monomer 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0098] It should be noted that the materials of the monomers 111 may be partially different, partially the same, or the materials of all the monomers 111 may be different.

[0099] In some embodiments, see Figure 1 The circumferential side wall of the monomer 111 defines a second air channel 11 a.

[0100] Exemplarily, the aerosol generating substrate 11 is spirally formed by at least one monomer 111 to form a spiral aerosol generating substrate 11, and the circumferential side walls of the monomer 111 forming the spiral aerosol generating substrate 11 define the second air channel 11a. The second air channel 11a is in a spiral shape.

[0101] The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the aerosol extraction efficiency. It also increases the impact of the airflow, so that the aerosol can be evenly mixed, improves the uniformity of the aerosol, and thus improves the user experience.

[0102] Exemplarily, a second air channel 11 a is defined between the monomers 111 .

[0103] In some embodiments, see Figures 5 to 8 The aerosol generating matrix 11 is composed of a plurality of connected monomers 111 , and a second air channel 11 a is defined between each monomer 111 .

[0104] For other implementations, see Figures 2 to 4 The aerosol generating matrix 11 is formed by spirally winding a plurality of monomers 111 , and a second air channel 11 a is defined between each monomer 111 .

[0105] Exemplarily, the aerosol generating substrate 11 is spirally formed from at least one monomer 111. In some embodiments, see Figure 2 The aerosol-generating substrate 11 is spirally formed from a monomer 111. For example, during the manufacturing process of the monomer 111, the monomer 111 is formed into the aerosol-generating substrate 11 by plastic rotation.

[0106] The circumferential side wall of the monomer 111 of the spiral aerosol generating matrix 11 defines a second air channel 11a. The second air channel 11a is spiral. The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the extraction efficiency of the aerosol. It will also increase the impact force of the airflow, so that the aerosol can be evenly mixed, improve the uniformity of the aerosol, and thus improve the user experience.

[0107] In addition, the spiral second air channel 11 a can adjust the flow rate of the airflow in the second air channel 11 a by changing the spiral angle, thereby changing the extraction rate of the aerosol generated by the monomer 111 by the airflow.

[0108] The aerosol generating matrix 11 is spirally formed from a monomer 111. The medium of the monomer 111 releases aerosol when heated, and is collected into the first airway 111a and / or the second airway 11a through the gaps or micro-airways between the wall materials of the monomer 111, so that the first airway 111a and / or the second airway 11a can extract the aerosol. The second airway 11a increases the flow rate of the aerosol by extending the flow path of the airflow, which is beneficial to improving the utilization rate of the monomer 111 during use and achieving the purpose of short-time and high release.

[0109] For example, in some other embodiments, see Figures 2 to 4 The aerosol generating matrix 11 is formed by spirally winding a plurality of monomers 111. By providing a combination mode of spirally winding a plurality of monomers 111, the heating uniformity of the aerosol generating matrix 11 is improved, thereby improving the user experience.

[0110] Since the aerosol generating matrix 11 is formed by spirally winding a plurality of monomers 111 , the outer wall of the connection between the plurality of monomers 111 is spiral-shaped, thereby increasing the flow speed of the aerosol along the outer wall of the connection between the plurality of monomers 111 .

[0111] The materials of the monomers 111 in this embodiment can be the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the taste consistency of the aerosol, thereby improving the consistency of suction.

[0112] The materials of the monomers 111 in this embodiment can also be different. Thus, different flavors can be combined. By setting the materials of the monomers 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0113] The aerosol generating matrix 11 in this embodiment defines a second air channel 11a between each monomer 111. That is, the second air channel 11a is defined between each monomer 111 of the spiral aerosol generating matrix 11. The second air channel 11a is in a spiral shape. The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the extraction efficiency of the aerosol. It will also increase the impact force of the airflow, so that the aerosol can be evenly mixed, improve the uniformity of the aerosol, and thus improve the user experience.

[0114] In some embodiments, see Figures 2 to 4, each monomer 111 is spirally formed around the center line of the aerosol generating matrix 11. In this way, each monomer 111 can be spirally wound uniformly, so that the medium of the aerosol generating matrix 11 is evenly distributed, thereby improving the overall heating uniformity of the medium and improving the use experience of consumers.

[0115] Of course, in other embodiments, the monomers 111 may not all be spirally formed around the center line of the aerosol generating matrix 11, that is, the medium of the aerosol generating matrix 11 is not evenly distributed, and the release of the aerosol may be adjusted according to the heating method.

[0116] In some embodiments, see Figure 2 The monomer 111 includes a linear monomer 1111 and at least one helical monomer 1112 , and the helical monomer 1112 is helically wound around the linear monomer 1111 .

[0117] The linear monomer 1111 is, for example, a monomer 111 extending along a straight line.

[0118] The helical monomer 1112 is, for example, a monomer 111 extending along a helical line.

[0119] The spiral monomer 1112 is spirally wound around the linear monomer 1111, that is, the central line of the linear monomer 1111 is taken as the spiral center, that is, the spiral monomer 1112 and the linear monomer 1111 are spirally wound to form the aerosol generating matrix 11.

[0120] In this embodiment, the spiral monomer 1112 and the linear monomer 1111 can be set to different materials. In this way, when the central heating method is adopted, the linear monomer 1111 is preferably heated and releases aerosol. After the linear monomer 1111 has released the aerosol, the spiral monomer 1112 is heated. At this time, the smoking flavor can be switched, which can increase the fun of consumers and enrich the smoking experience. In addition, the first airway 111a of the linear monomer 1111 has a regulating effect on the aerosol.

[0121] like Figure 2 In the illustrated embodiment, the aerosol generating matrix 11 is composed of three spiral monomers 1112 and a linear monomer 1111 in the center. In this embodiment, the spiral monomers 1112 and the linear monomers 1111 can be made of different materials.

[0122] like Figure 3In the illustrated embodiment, the aerosol generating matrix 11 includes two monomers 111, and the two monomers 111 are spirally wound. In this embodiment, the two monomers 111 can be set to the same material, so that the aerosol release rate of the monomers 111 during the heating process can be made consistent by regulating the heating rate of the monomers 111 during the heating process. In addition, the two monomers 111 can also be made of different materials, so that the aroma components produced in the medium are mixed during the suction process, thereby improving the consistency of the overall aerosol taste during the heating process. The shapes of the two monomers 111 are preferably the same, and are spirally formed about a common central axis.

[0123] like Figure 4 In the embodiment shown, three monomers 111 are included, and the three monomers 111 are spirally wound. In this embodiment, the three monomers 111 can be set to the same material, so that the circumferential side walls of the monomers 111 that form the spiral aerosol generating matrix 11 define the second air channel 11a. The second air channel 11a is in a spiral shape. The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the extraction efficiency of the aerosol. In addition, at least one monomer 111 can also be made of different materials to play a role in flavor blending and increasing the consistency of taste during the suction process. The shapes of the three monomers 111 are preferably the same, and are spirally formed about a common central axis.

[0124] The aerosol generating substrate 11 is composed of a plurality of monomers 111 connected together, and the shape of the aerosol generating substrate 11, that is, the arrangement of the plurality of monomers 111 is not limited here. In some embodiments, on a plane perpendicular to the length direction of the aerosol generating substrate 11, the cross-sectional shape of the aerosol generating substrate 11 is in the shape of a straight line, a polygon, a circle, or an ellipse.

[0125] The materials of the monomers 111 in this embodiment can be the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the taste consistency of the aerosol, thereby improving the consistency of suction.

[0126] The materials of the monomers 111 in this embodiment can also be different. Thus, different flavors can be combined. By setting the materials of the monomers 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0127] The aerosol generating matrix 11 in this embodiment defines a second air channel 11a between each monomer 111. That is, the second air channel 11a is defined between each monomer 111 forming the aerosol generating matrix 11. The second air channel 11a is in a straight line. It is beneficial to increase the contact area between the monomer 111 and the airflow, that is, it is beneficial for the aerosol released by the monomer 111 to be transmitted to the near-lip end through the first air channel 111a and the second air channel 11a at the same time, thereby improving the extraction efficiency of the aerosol. In addition, since the second air channel 11a is formed between each monomer 111, during the continuous inhalation process, the aerosol can preheat the next monomer 111, which can reduce the waiting time required for the next stage of inhalation.

[0128] In some embodiments, see Figures 5 to 8 The aerosol generating matrix 11 is composed of a plurality of monomers 111 connected together, and all the monomers 111 are linearly arranged along a first direction Z1.

[0129] All the monomers 111 are arranged linearly along the first direction Z1 , that is, the monomers 111 have a special arrangement rule, so that it is convenient to connect the monomers 111 according to the predetermined arrangement rule during the molding process.

[0130] It should be noted that the first direction Z1 can be a straight line or a curve.

[0131] When the first direction Z1 is a straight line, the cross-sectional shape of the aerosol generating substrate 11 is in the shape of a straight line. Figure 5 and Figure 7 , the monomers 111 are arranged along a straight line, and the cross-sectional shape of the aerosol generating matrix 11 formed by connecting the monomers 111 is in the shape of a straight line. In this embodiment, the peripheries of the monomers 111 can be connected by tangent connection, which can be applied to a flat heater.

[0132] The first direction Z1 is a curve, and the cross-sectional shape of the aerosol generating substrate 11 is polygonal, circular or elliptical. Figure 6 and Figure 8 , the monomers 111 are arranged along the circumference, and the cross-sectional shape of the aerosol generating matrix 11 is triangular or quadrilateral. In this embodiment, the center position of each monomer 111 also forms a second air channel 11a, so that during continuous inhalation, the aerosol can preheat the next monomer 111, which can reduce the waiting time required for the next stage of inhalation.

[0133] In some embodiments, see Figure 8 The aerosol generating matrix 11 is composed of a plurality of monomers 111 connected together, and all the monomers 111 are distributed on a plurality of trajectory lines, wherein the monomers 111 on a single trajectory line are linearly arranged along a first direction Z1, and a plurality of trajectory lines are arranged along a second direction Z2, and the first direction Z1 and the second direction Z2 are not parallel.

[0134] That is, the multiple rows of monomers 111 are not arranged along a straight line. A two-dimensional coordinate system is formed by the first direction Z1 and the second direction Z2, and the arrangement of the monomers 111 can be defined by the first direction Z1 and the second direction Z2.

[0135] It should be noted that the first direction Z1 can be a straight line or a curve; the second direction Z2 can be a straight line or a curve.

[0136] Exemplarily, the monomers 111 on a single trajectory are arranged in a straight line along a first direction Z1, and the multiple trajectory lines are arranged in a straight line along a second direction Z2, and the first direction Z1 and the second direction Z2 intersect. That is, the first direction Z1 and the second direction Z2 are two non-parallel straight lines, so that the cross-sectional shape of the aerosol generating substrate 11 is a quadrilateral.

[0137] For example, see Figure 8 The monomers 111 are distributed in an array, the number of monomers 111 in the first direction Z1 and the number of monomers 111 in the second direction Z2 are the same, the monomers 111 on a single track line are equidistant, and the intervals between the track lines are equal.

[0138] For example, when the first direction Z1 and the second direction Z2 are straight line directions perpendicular to each other, see Figure 8 The monomers 111 are distributed in an array, the monomers 111 on a single trajectory are equidistant, and the spacing between the trajectory lines is equal, that is, the distance between two adjacent monomers 111 on a single trajectory is equal to the distance between two adjacent trajectory lines.

[0139] For example, in some embodiments, please refer to Figure 8 The monomers 111 are distributed in a matrix. Specifically, the matrix distribution refers to an N*M overall arrangement, wherein N represents the number of monomers 111 on a single trajectory line, and M represents the number of trajectory lines. N and M can be the same (the number of monomers 111 in the first direction Z1 and the second direction Z2 are the same), or different (the number of monomers 111 in the first direction Z1 and the second direction Z2 are different).

[0140] like Figure 8 , the monomers 111 are arranged in a matrix, and the cross-section of the aerosol generating matrix 11 is square. In this embodiment, the center of each monomer 111 also forms a second air channel 11a, so that during continuous inhalation, the aerosol can preheat the next monomer 111, which can reduce the waiting time required for the next stage of inhalation.

[0141] Exemplarily, the monomers 111 on a single trajectory are arranged along a circumferential direction around the center of the aerosol generating substrate 11 , and the plurality of trajectory lines are arranged in concentric circles along the radial direction of the aerosol generating substrate 11 .

[0142] The circumferential direction around the center of the aerosol generating substrate 11 is equivalent to the first direction Z1, and the radial direction of the aerosol generating substrate 11 is equivalent to the second direction Z2, that is, the plurality of monomers 111 may be arranged in a ring shape.

[0143] In a specific embodiment, all monomers 111 are distributed in a plurality of circular rings, and the cross-sectional area of ​​the monomers 111 is circular, and the monomers 111 of two adjacent rings are staggered, that is, each hole of one ring is located between two holes of the other ring. In this embodiment, the circular ring distribution of the cylindrical holes has the advantage that the distance between two adjacent monomers 111 is equal, and the number of adjacent outer ring monomers 111 and the number of adjacent inner ring monomers 111 are arranged in a certain supplementary regularity. In this way, the distance between adjacent monomers 111 can be made the same, and the release of aerosol is uniform and stable.

[0144] In this embodiment, the monomers 111 are arranged along the circumference, and the cross-sectional shape of the aerosol generating matrix 11 is circular. In this embodiment, the center position of each monomer 111 also forms a second air channel 11a, so that during continuous inhalation, the aerosol can preheat the next monomer 111, which can reduce the waiting time required for the next stage of inhalation.

[0145] For example, see Figure 8 , the monomers 111 of a single trajectory line are equidistantly arranged. Among them, equidistant arrangement means that the distance between the hole centers of two adjacent monomers 111 is equal. As a result, the uniformity of aerosol release from the aerosol generating matrix 11 can be improved during the heating and suction process, and it is beneficial to the uniformity of aerosol transmission and heating, thereby improving the user's suction experience. In other words, the aerosol generating matrix 11 of the embodiment of the present application can improve the user's experience.

[0146] For example, in some embodiments, the first air channel 111a runs through at least one end of the monomer 111 along the length direction, and the first air channel 111a is a straight air channel. A straight air channel means that the air channel extends in a straight line, which is conducive to extracting the effective components inside the monomer 111.

[0147] In other embodiments, the first air channel 111a passes through at least one end of the monomer 111 along the length direction. The first air channel 111a is in a spiral shape consistent with the monomer 111, which can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the first air channel 111a, and increase the flow rate of the aerosol. At the same time, it can also increase the surface area of ​​the first air channel 111a, which is more conducive to the extraction of effective ingredients inside the monomer 111.

[0148] Exemplarily, the first air channel 111 a penetrates both ends of the monomer 111 along the length direction, and the first air channel 111 a is spiral or linear.

[0149] The first air channel 111a runs through both ends of the monomer 111 along the length direction, that is, the first air channel 111a extends along the length direction of the monomer 111, and the air flow can flow from one end of the monomer 111 through the first air channel 111a to the other end of the monomer 111. Preferably, the first air channel 111a is parallel to the central axis of the monomer 111.

[0150] The first air channel 111 a is in a linear shape, which means that the air channel extends in a straight line, which is beneficial for extracting the effective components inside the monomer 111 .

[0151] The spiral shape of the first air channel 111a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the first air channel 111a, and increase the flow rate of the aerosol. At the same time, it can also increase the surface area of ​​the first air channel 111a, which is more conducive to the extraction of effective ingredients inside the monomer 111.

[0152] Ten specific embodiments are briefly introduced below with reference to the accompanying drawings.

[0153] First embodiment

[0154] See also Figure 1 In this embodiment, the aerosol generating substrate 11 is spirally formed from a monomer 111. For example, during the manufacturing process of the monomer 111, the monomer 111 may be formed into the aerosol generating substrate 11 by plastic rotation.

[0155] The circumferential side wall of the monomer 111 of the spiral aerosol generating matrix 11 defines a second air channel 11a. The second air channel 11a is spiral. The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the extraction efficiency of the aerosol. It will also increase the impact force of the airflow, so that the aerosol can be evenly mixed, improve the uniformity of the aerosol, and thus improve the user experience.

[0156] In addition, the spiral second air channel 11 a can adjust the flow rate of the airflow in the second air channel 11 a by changing the spiral angle, thereby changing the extraction rate of the aerosol generated by the monomer 111 by the airflow.

[0157] The aerosol generating matrix 11 is spirally formed from a monomer 111. The medium of the monomer 111 releases aerosol when heated, and is collected into the first airway 111a and / or the second airway 11a through the gaps or micro-airways between the wall materials of the monomer 111, so that the first airway 111a and / or the second airway 11a can extract the aerosol. The second airway 11a increases the flow rate of the aerosol by extending the flow path of the airflow, which is beneficial to improving the utilization rate of the monomer 111 during use and achieving the purpose of short-time and high release.

[0158] In some embodiments, the first air channel 111 a is a straight air channel, which means that the air channel extends in a straight line, which is conducive to extracting the effective components inside the monomer 111 .

[0159] In other embodiments, the first air channel 111a is in a spiral shape consistent with the monomer 111, which can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the first air channel 111a, and increase the flow rate of the aerosol. At the same time, it can also increase the surface area of ​​the first air channel 111a, which is more conducive to the extraction of effective ingredients inside the monomer 111.

[0160] Second embodiment

[0161] See also Figure 2 In this embodiment, the aerosol generating matrix 11 is composed of three spiral monomers 1112 and a linear monomer 1111 in the center.

[0162] The linear monomer 1111 is, for example, a monomer 111 extending along a straight line.

[0163] The helical monomer 1112 is, for example, a monomer 111 extending along a helical line.

[0164] The spiral monomer 1112 is spirally wound around the linear monomer 1111, that is, the central line of the linear monomer 1111 is taken as the spiral center, that is, the spiral monomer 1112 and the linear monomer 1111 are spirally wound to form the aerosol generating matrix 11.

[0165] Third embodiment

[0166] See also Figure 3 In this embodiment, the aerosol generating matrix 11 is formed by spirally winding two monomers 111. By setting a combination mode of spirally winding two monomers 111, the heating uniformity of the aerosol generating matrix 11 is improved, thereby improving the user experience.

[0167] The materials of the monomers 111 in this embodiment can be the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the taste consistency of the aerosol, thereby improving the consistency of suction.

[0168] The materials of the monomers 111 in this embodiment can also be different. Thus, different flavors can be combined. By setting the materials of the monomers 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0169] The aerosol generating matrix 11 in this embodiment defines a second air channel 11a between each monomer 111. That is, the second air channel 11a is defined between each monomer 111 of the spiral aerosol generating matrix 11. The second air channel 11a is in a spiral shape. The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the extraction efficiency of the aerosol. It will also increase the impact force of the airflow, so that the aerosol can be evenly mixed, improve the uniformity of the aerosol, and thus improve the user experience.

[0170] In some embodiments, each monomer 111 is spirally formed around the center line of the aerosol generating substrate 11. In this way, each monomer 111 can be spirally wound uniformly to make the medium of the aerosol generating substrate 11 uniformly distributed, thereby improving the overall heating uniformity of the medium and enhancing the user experience of consumers.

[0171] Of course, in other embodiments, the monomers 111 may not all be spirally formed around the center line of the aerosol generating matrix 11, that is, the medium of the aerosol generating matrix 11 is not evenly distributed, and the release of the aerosol may be adjusted according to the heating method.

[0172] Fourth embodiment

[0173] See also Figure 4 In this embodiment, the structure of the aerosol generating matrix 11 is substantially the same as that of the third embodiment, and the main differences include: in this embodiment, the aerosol generating matrix 11 is formed by spirally winding three monomers 111.

[0174] Fifth embodiment

[0175] See also Figure 5 In this embodiment, the aerosol generating matrix 11 is composed of two monomers 111 connected together.

[0176] The two monomers 111 are arranged along a straight line, and the cross-sectional shape of the aerosol generating matrix 11 formed by connecting the monomers 111 is in the shape of a straight line. In this embodiment, the peripheries of the monomers 111 can be connected by tangent connection, which can be applied to a flat heater.

[0177] The materials of the monomers 111 in this embodiment can be the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the taste consistency of the aerosol, thereby improving the consistency of suction.

[0178] The materials of the monomers 111 in this embodiment can also be different. Thus, different flavors can be combined. By setting the materials of the monomers 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0179] The aerosol generating matrix 11 in this embodiment defines a second air channel 11a between each monomer 111. That is, the second air channel 11a is defined between each monomer 111 forming the aerosol generating matrix 11. The second air channel 11a is in a straight line. It is beneficial to increase the contact area between the monomer 111 and the airflow, that is, it is beneficial for the aerosol released by the monomer 111 to be transmitted to the near-lip end through the first air channel 111a and the second air channel 11a at the same time, thereby improving the extraction efficiency of the aerosol. In addition, since the second air channel 11a is formed between each monomer 111, during the continuous inhalation process, the aerosol can preheat the next monomer 111, which can reduce the waiting time required for the next stage of inhalation.

[0180] Sixth embodiment

[0181] See also Figure 6 In this embodiment, the structure of the aerosol generating matrix 11 is substantially the same as that of the fifth embodiment, and the main differences include: the aerosol generating matrix 11 is composed of three monomers 111 connected together.

[0182] The three monomers 111 are arranged along the circumference, and the cross-sectional shape of the aerosol generating substrate 11 is triangular.

[0183] In this embodiment, a second air channel 11 a is also formed at the center of each monomer 111 , so that during continuous inhalation, the aerosol can preheat the next monomer 111 , thereby reducing the waiting time required for the next stage of inhalation.

[0184] Seventh embodiment

[0185] See also Figure 7In this embodiment, the structure of the aerosol generating matrix 11 is substantially the same as that of the fifth embodiment, and the main differences include: in this embodiment, the aerosol generating matrix 11 is composed of four monomers 111 connected together.

[0186] Eighth embodiment

[0187] See also Figure 8 In this embodiment, the structure of the aerosol generating matrix 11 is substantially the same as that of the sixth embodiment, and the main differences include: in this embodiment, the aerosol generating matrix 11 is composed of four monomers 111 connected together.

[0188] The four monomers 111 are distributed in an array, and the cross-sectional shape of the aerosol generating matrix 11 is a square.

[0189] Ninth embodiment

[0190] See also Fig.10 In this embodiment, the aerosol generating matrix 11 is composed of four monomers 111 connected together.

[0191] The four monomers 111 are distributed in an array, and the cross-sectional shape of the aerosol generating matrix 11 is a square.

[0192] The materials of the monomers 111 in this embodiment can be the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the taste consistency of the aerosol, thereby improving the consistency of suction.

[0193] The materials of the monomers 111 in this embodiment can also be different. Thus, different flavors can be combined. By setting the materials of the monomers 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0194] The aerosol generating matrix 11 in this embodiment defines a second air channel 11a between each monomer 111. That is, the second air channel 11a is defined between each monomer 111 forming the aerosol generating matrix 11. The second air channel 11a is in a straight line. It is beneficial to increase the contact area between the monomer 111 and the airflow, that is, it is beneficial for the aerosol released by the monomer 111 to be transmitted to the near-lip end through the first air channel 111a and the second air channel 11a at the same time, thereby improving the extraction efficiency of the aerosol. In addition, since the second air channel 11a is formed between each monomer 111, during the continuous inhalation process, the aerosol can preheat the next monomer 111, which can reduce the waiting time required for the next stage of inhalation.

[0195] The aerosol generating product 1 includes an aerosol generating matrix 11, a cooling section 121 and a filtering section 122. When in use, the aerosol generating matrix 11 is heated, and the generated aerosol is transmitted to the first air channel 111a and / or the second air channel 11a through the micropores, and the aerosol generated by the aerosol generating matrix 11 is extracted and mixed through the first air channel 111a and / or the second air channel 11a, and then flows through the cooling section 121 to reduce the temperature of the aerosol, and then passes through the filtering section 122 to adsorb tar (large particle components) in the aerosol and is inhaled by consumers.

[0196] Tenth embodiment

[0197] like Fig.11 As shown, in this embodiment, the aerosol generating matrix 11 is formed by spirally winding three monomers 111. By setting a combination of three monomers 111 spirally winding, the heating uniformity of the aerosol generating matrix 11 is improved, thereby improving the user experience.

[0198] The materials of the monomers 111 in this embodiment can be the same. By setting the materials of the monomers 111 to be the same, it is beneficial to maintain the taste consistency of the aerosol, thereby improving the consistency of suction.

[0199] The materials of the monomers 111 in this embodiment can also be different. Thus, different flavors can be combined. By setting the materials of the monomers 111 to be different, when the monomer 111 being released reaches a specified time or number of puffs, the heating element starts to heat the next monomer 111, and the puffing flavor can be switched at this time, which can increase the fun of consumers and enrich the puffing experience.

[0200] The aerosol generating matrix 11 in this embodiment defines a second air channel 11a between each monomer 111. That is, the second air channel 11a is defined between each monomer 111 of the spiral aerosol generating matrix 11. The second air channel 11a is in a spiral shape. The spiral second air channel 11a can greatly extend the flow path of the airflow, precipitate the aerosol from the monomer 111 to the second air channel 11a, increase the flow rate of the aerosol, and thus improve the extraction efficiency of the aerosol. It will also increase the impact force of the airflow, so that the aerosol can be evenly mixed, improve the uniformity of the aerosol, and thus improve the user experience.

[0201] In this embodiment, each monomer 111 is spirally formed around the center line of the aerosol generating matrix 11. In this way, each monomer 111 can be spirally wound uniformly to make the medium of the aerosol generating matrix 11 uniformly distributed, thereby improving the overall heating uniformity of the medium and enhancing the use experience of consumers.

[0202] The aerosol generating product 1 includes an aerosol generating matrix 11, a cooling section 121 and a filtering section 122. When in use, the aerosol generating matrix 11 is heated, and the generated aerosol is transmitted to the first air channel 111a and / or the second air channel 11a through the micropores, and the aerosol generated by the aerosol generating matrix 11 is extracted and mixed through the first air channel 111a and / or the second air channel 11a, and then flows through the cooling section 121 to reduce the temperature of the aerosol, and then passes through the filtering section 122 to adsorb tar (large particle components) in the aerosol and is inhaled by consumers.
