[0059] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or suggesting relative importance or implicitly indicating the quantity or order of the indicated technical features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement situation between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment that includes a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0061] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0062] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0063] Please refer to Figures 1-12 Some embodiments of the present application provide an aerosol-generating article 2 , which can interact with an aerosol-generating device 1 and generate aerosol under the power provided by the aerosol-generating device 1 .

[0064] The aerosol-generating article 1 comprises a plurality of aerosol bodies 21 spaced apart from each other and a housing 22 for accommodating the plurality of aerosol bodies 21 , wherein each aerosol body 21 comprises an aerosol substrate 211 , which can generate aerosol after being heated.

[0065] As used herein, the term "plurality" refers to two or more.

[0066] As used herein, the term "aerosol substrate" refers to a substrate that can release volatile substances to form an inhalable aerosol. The aerosol substrate may include a tobacco-containing material that contains volatile tobacco flavor compounds that are released from the substrate after heating. Specifically, the aerosol substrate may be an aerosol substrate that contains tobacco, preferably an aerosol substrate that contains solid tobacco. Alternatively, the aerosol substrate may include a non-tobacco material. The aerosol substrate may also include an aerosol forming agent. Examples of suitable aerosol forming agents are glycerol and propylene glycol.

[0067] Optionally, the aerosol substrate may contain additional tobacco or non-tobacco volatile flavor compounds that are released when the aerosol substrate is heated. The aerosol substrate may also contain microcapsules, for example, containing additional tobacco or non-tobacco volatile flavor compounds, and such microcapsules may melt during heating of the solid aerosol substrate.

[0068] The aerosol substrate 211 may be substantially disk-shaped or circular. The aerosol substrate 211 may be substantially rectangular.

[0069] Preferably, the aerosol substrate is a tobacco sheet comprising tobacco material, fibers, a binder and an aerosol former. Preferably, the tobacco sheet is a cast leaf. Cast leaf is a form of reconstituted tobacco formed from a slurry comprising tobacco particles, fiber particles, an aerosol former, a binder and, for example, flavorings.

[0070] The tobacco particles may be in the form of tobacco dust having particles of about 30 to 250 microns, preferably about 30 to 80 microns or 100 to 250 microns, depending on the desired sheet thickness and the casting gap, which generally defines the thickness of the sheet.

[0071] The thickness of the aerosol substrate 211 may be in the range of 0.2 mm to 6 mm, preferably 0.5 mm to 4 mm, more preferably 0.2 mm to 1 mm. For example, the thickness of the aerosol substrate 211 may be about 0.4 mm.

[0072] The fiber particles may comprise tobacco stem material, stalks, or other tobacco plant material, as well as other cellulose-based fibers, such as wood fibers with a low lignin content. The fiber particles may be selected based on the need to produce sufficient tensile strength for the sheet and a low lignin content, such as between about 2% and 15%. Alternatively, fibers such as vegetable fibers may be used in conjunction with the above-described fiber particles, or, in an alternative embodiment, may include hemp and bamboo.

[0073] In some embodiments, the aerosol-generating article 2 further includes a heating element 212 , which is configured to release heat to heat the aerosol substrate 211 , so that the aerosol substrate 211 generates aerosol.

[0074] There may be a plurality of heating elements 212. The plurality of heating elements 212 may be provided in a one-to-one correspondence with the plurality of aerosol bodies 21, so that each heating element 212 mainly provides heat to one of the aerosol bodies 21 to enable the aerosol body 21 to generate aerosol.

[0075] The heating element 212 may be a component of the aerosol 21 , that is, at least one aerosol 21 may include not only the aerosol substrate 211 but also the heating element 212 for heating the aerosol substrate 211 .

[0076] In some embodiments, the aerosol body 21 further includes a heating element 212 for heating the aerosol substrate 211 to generate an aerosol.

[0077] The heating element 212 can be in direct contact with the aerosol substrate 211. In this regard, as an example, the aerosol substrate 211 is bonded to the surface of the heating element 212 via an adhesive. As an example, the aerosol substrate 211 is formed into a slurry and coated on the surface of the heating element 212. After drying, an aerosol substrate coating layer is formed on the surface of the heating element 212. As an example, the heating element 212 is fixed to a side wall of the housing 22. The aerosol-generating article 2 further includes a fixing member 23 that is in interference fit with the aerosol substrate 211, thereby ensuring contact between the aerosol substrate 211 and the heating element 212. As an example, at least a portion of the heating element 212 is disposed within the aerosol substrate 211.

[0078] The heating element 212 may be spaced apart from the corresponding aerosol substrate 211 . For example, the heating element 212 may be disposed on the outer surface of the housing 22 or outside the housing 22 , while the aerosol substrate 211 may be disposed inside the housing 22 .

[0079] In some embodiments, the heating element 212 comprises a susceptor. As used herein, the term "susceptor" refers to a material that can convert electromagnetic energy into heat. When located within a varying electromagnetic field, eddy currents induced in the susceptor cause the susceptor to heat. In such embodiments, the aerosol generating device 1 may include a magnetic field generator 11. The magnetic field generator 11 generates a varying magnetic field to heat the susceptor within the varying magnetic field. During use, the susceptor is located within the varying magnetic field generated by the magnetic field generator 11. The magnetic field generator 11 is electrically connected to a power supply assembly within the aerosol generating device 1, which provides the magnetic field generator 11 with current to generate the varying magnetic field. The magnetic field generator 11 may include one or more induction coils that generate the varying magnetic field. In some embodiments, the aerosol generating device 1 is capable of generating a varying magnetic field between 10 MHz and 30 MHz, for example, between 20 MHz and 10 MHz, or for example, between 50 MHz and 7 MHz. In some embodiments, the aerosol generating device is capable of generating a varying magnetic field having a field strength (H field) between 1 and 5 kA / m, such as between 2 and 3 kA / m, such as about 2.5 kA / m.

[0080] The susceptor may comprise metal or carbon. In some embodiments, the susceptor may comprise a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In some embodiments, the susceptor comprises a nickel-iron alloy. In some embodiments, the susceptor comprises 400 series stainless steel, including 410, 420, or 430 grade stainless steel.

[0081] In some embodiments, the heating element 212 includes a resistive material or an infrared coating. The resistive material can generate Joule heat when powered by the power supply assembly. The infrared coating can emit infrared rays when powered by the power supply assembly.

[0082] In some embodiments, the heating element 212 is generally disk-shaped or circular. In some embodiments, the heating element 212 is generally rectangular. In some embodiments, the heating element 212 and the aerosol substrate 211 have approximately the same shape.

[0083] It should be noted that the inclusion of the heating element 212 in the aerosol body 21 is optional and not mandatory. In other embodiments, the aerosol generating device includes a heating element, which heats the aerosol substrate in the aerosol-generating article. Furthermore, when the aerosol-generating article is removed from the aerosol generating device, the heating element in the aerosol generating device may remain in the aerosol generating device.

[0084] In some embodiments, multiple aerosol bodies 21 capable of generating aerosols are spaced apart from each other and distributed within the housing 22, such that the multiple aerosol bodies 21 are independent of each other within the housing 22. Prior to being housed within the housing 22, the multiple aerosol bodies 21 may already be independent of each other. Furthermore, the multiple aerosol bodies 21 disposed within the housing 22 are configured to generate aerosols at different times. For example, the multiple aerosol bodies 21 disposed within the housing 22 may generate aerosols sequentially according to a predetermined sequence. Furthermore, the amount of aerosol generated by each aerosol substrate 211 is sufficient for a user to inhale in one puff, so the number of puffs of the aerosol-generating article 2 may be the same as the number of aerosol bodies 21.

[0085] In some embodiments, reference may be made to Figure 5 、 Figure 6 and Figure 10 The housing 22 has an air flow channel 25 therein. The aerosols 21 can be retained on the sidewalls of the housing 22, and the multiple aerosol substrates 211 can be in fluid communication with the same or different air flow channels 25. The multiple aerosols 21 contained in the housing 22 can be configured so that they share a common air flow channel 25 for aerosol transmission. Thus, the housing 22 can have a single air inlet and a single air outlet, simplifying and stabilizing the structure of the housing 22. At least two of the multiple aerosols 21 contained in the housing 22 can be configured so that they transmit aerosols through two different air flow channels 25.

[0086] In some embodiments, reference may be made to Figure 10 and Figure 11 , the aerosols 21 are all retained on the same side wall in the shell 22.

[0087] In some embodiments, reference may be made to Figure 5 and Figure 6 The housing 22 includes a first sidewall 221 and a second sidewall 222 that are arranged non-coplanarly. Some of the aerosols 21 are retained on the first sidewall 221, while some of the aerosols 21 are retained on the second sidewall 222. The first sidewall 221 and the second sidewall 222 can be located on different sides of the same airflow channel 25. For example, the first sidewall 221 and the second sidewall 222 can both face the same airflow channel 25. This allows the at least two aerosol substrates 211 to fluidically communicate with the airflow channel 25 from different directions. This not only increases the distribution density of the aerosols 21 within the limited space within the housing 22, allowing the limited space within the housing 22 to accommodate exponentially more aerosols 21 without exponentially increasing the volume of the airflow channel 25, but also allows for a more concentrated distribution of the aerosols 21, thereby reducing the volume of both the housing 22 and the airflow channel 25.

[0088] Preferably, you can refer to Figure 5 The airflow channel 25 has a roughly rectangular cross-section. A rectangle has a smaller area than a circle. In one example, the width w of the airflow channel 25 is less than 15 mm. For example, the width w of the airflow channel 25 can be approximately 12 mm. In one example, the height h of the airflow channel 25 is less than 3 mm. For example, the height h of the airflow channel 25 can be approximately 2.7 mm. In one example, the difference between the width of the airflow channel 25 and the width of the aerosol substrate 211 is less than 5 mm. For example, the difference can be approximately 3.6 mm. It should be noted that when the aerosol substrate 211 is roughly disk-shaped or circular, the width of the aerosol substrate 211 is roughly the diameter of the disk or circle. When the aerosol substrate 211 is roughly disk-shaped or rectangular, the width of the aerosol substrate 211 is roughly the width of the rectangle. In one example, the difference between the width w of the airflow channel 25 and the width of the aerosol substrate 211 is less than 1 / 2 of the width of the aerosol substrate 211. In a specific embodiment, the width of the aerosol substrate 211 is about 8.5 mm, and the width w of the air flow channel 25 is about 12 mm.

[0089] It should be noted that, in other embodiments, the cross-section of the air flow channel 25 may also be other non-circular shapes.

[0090] The aerosol 21 can be roughly sheet-shaped, and the first side wall 221 can have a planar inner surface. Therefore, the first side wall 221 can better retain the aerosol 21 and facilitate the assembly of the aerosol 21 on the first side wall 221. The second side wall 222 can also have a planar inner surface to better retain the aerosol 21.

[0091] Furthermore, the first side wall 221 may be substantially flat-plate-shaped, and the second side wall 222 may also be substantially flat-plate-shaped.

[0092] The first side wall 221 and the second side wall 222 may be two adjacent side walls of the housing 22. For example, the cross section of the housing 22 may be substantially triangular, and thus the housing 22 further includes a third side wall, which may also hold some of the aerosols 21.

[0093] The first sidewall 221 and the second sidewall 222 can be two sidewalls spaced apart on the housing 22. Preferably, the first sidewall 221 and the second sidewall 222 are disposed opposite each other. For example, the cross-section of the housing 22 can be roughly quadrilateral. Based on this, the housing 22 also includes a third sidewall and a fourth sidewall. The first sidewall 221 is disposed opposite the second sidewall 222, and the third sidewall is disposed opposite the fourth sidewall. The third sidewall and / or the fourth sidewall can also retain some of the aerosols 21. To reduce the height of the housing 22, the third and fourth sidewalls are preferably left empty, with no aerosols 21 disposed thereon. The third and fourth sidewalls respectively define the boundaries of opposite sides of the airflow channel 25. Preferably, the first sidewall 221, the second sidewall 222, the third sidewall, and the fourth sidewall are all roughly flat, so that the housing 22 is roughly box-shaped.

[0094] When the first side wall 221 and the second side wall 222 are disposed opposite each other, the distance between the first side wall 221 and the second side wall 222 can remain substantially constant along the length direction of the housing 22. For example, the first side wall 221 and the second side wall 222 both have substantially planar inner surfaces, and the inner surface of the first side wall 221 and the inner surface of the second side wall 222 are parallel to each other. In other embodiments, when the first side wall 221 and the second side wall 222 are disposed opposite each other, the distance between the first side wall 221 and the second side wall 222 can gradually increase or decrease along the length direction of the housing 22.

[0095] In some embodiments, the housing 22 has multiple sidewalls, and the aerosols 21 can all be disposed on the same sidewall. Furthermore, at least one of the multiple sidewalls of the housing 22 has a generally planar inner surface, and the aerosols 21 can all be retained on the same generally planar inner surface. Furthermore, at least one of the multiple sidewalls of the housing 22 is generally flat, and the flat sidewall has a planar inner surface, so that the aerosols 21 can all be retained on the same flat sidewall of the housing 22.

[0096] In some embodiments, the housing 22 has a plurality of side walls, at least one of which is substantially rectangular, thereby providing the housing 22 with at least one substantially rectangular face. In other embodiments, at least one of the side walls of the housing 22 may be substantially trapezoidal, thereby providing the housing 22 with at least one substantially trapezoidal face.

[0097] It should be noted that the housing 22 may also have an arcuate sidewall, thereby having an arcuate surface. The housing 22 may also be substantially cylindrical, thereby having a circular surface.

[0098] In some embodiments, the housing 22 includes an open first port configured to allow ambient air to enter the airflow channel 25. The first sidewall 221 and the second sidewall 222 may partially define the first port. To prevent condensation formed by the aerosol in the airflow channel 25 from leaking from the first port, the aerosol-generating article 2 may further include a breathable wall 26 disposed on the first port to allow airflow to pass through. The breathable wall 26 may be at least partially located within the first port, thereby connecting the inner surfaces of the first and second sidewalls 221, 222. At least partially located outside the first port, thereby shielding the first port and connecting the ends of the first and second sidewalls 221, 222. As an example, the breathable wall 26 comprises a paper sheet having a plurality of air holes. As an example, the breathable wall 26 comprises a breathable fiber mass, such as breathable cotton, acetate fiber, a filter element, or cotton cloth, so that the breathable wall 26 can also absorb liquids.

[0099] In some embodiments, the housing 22 includes an open second port configured to allow gas in the gas flow channel 25 to flow out of the housing 22. The first sidewall 221 and the second sidewall 222 may define a portion of the second port.

[0100] The first port and the second port may be located on opposite sides of the housing 22 .

[0101] After the aerosol body 21 is contained in the housing 22, the aerosol substrate 211 can be positioned close to the airflow channel 25 to reduce the distance traveled by the aerosol generated by the aerosol substrate 211 into the airflow channel 25. Therefore, the aerosol substrate 211 can be positioned between the corresponding heating element 212 and the airflow channel 25.

[0102] Alternatively, after the aerosol body 21 is contained in the housing 22, the heating element 212 can be positioned near the airflow channel 25 to prevent aerosol generated by other aerosol substrates 211 from condensing on the corresponding aerosol substrate 211 and / or to volatilize condensed liquid thereon when heated. Based on this, the heating element 212 can be positioned between the corresponding aerosol substrate 211 and the airflow channel 25.

[0103] In some embodiments of the present application, the housing 22 is made of paper. Compared with plastic, paper is not only cheaper but also more environmentally friendly.

[0104] Based on this, in some embodiments, the housing 22 is formed by folding a sheet of paper. The flat sheet of paper can be folded into a three-dimensional shape with at least three side walls. For example, the housing 22 is generally in the shape of a square box with a quadrilateral cross-section, or the housing 22 is generally in the shape of a triangular prism with a generally triangular cross-section.

[0105] For example, you can refer to Figure 5 、 Figure 7 and Figure 8 、 Figure 10 and Figure 11 One side wall of the housing 22 includes a first connecting edge 223 and a second connecting edge 224 that at least partially overlap. The first connecting edge 223 and the second connecting edge 224 are located on opposite sides of the paper material forming the housing 22 after it is unfolded. The first connecting edge 223 and the second connecting edge 224 can be bonded to each other using an adhesive or double-sided tape to prevent the first connecting edge 223 or the second connecting edge 224 located on the inner side of the side wall from warping inward. The first connecting edge 223 and the second connecting edge 224 can have substantially the same height and length, but are not limited thereto.

[0106] For example, the paper material forming the shell 22 can overlap each other without edges after the shell 22 is formed. For example, the end of one side wall of the shell 22 abuts the inner surface of the other adjacent side wall, and the outer surfaces of the two side walls are covered and connected by tape. The tape can cover the seam between the two side walls, thereby sealing the seam and preventing aerosol leakage through the seam.

[0107] In some embodiments, the housing 22 is formed by splicing a plurality of paper sheets, at least some of which may be flat; or at least some of which may be folded with folded corners.

[0108] You can refer to Figure 7 and Figure 8 、 Figure 10 and Figure 11 Before folding or splicing the paper to form the shell 22, the aerosol 21 can be placed on the appropriate position of the paper, and then the paper is folded or spliced. After the shell 22 is formed, each aerosol 21 is already located on the corresponding side wall of the shell 22.

[0109] As an example, the heating element 212 includes a fixing portion, at least partially embedded in a sidewall of the housing 22, for example, embedded in the first sidewall 221 and / or the second sidewall 222. The fixing portion can be embedded in the sidewall by puncturing paper, or a hole can be pre-punched in the paper shell 22, and then at least partially embedded in the hole. It should be noted that the fixing portion of the heating element 212 is optional, and other methods can also be used to retain the heating element 212 on the sidewall of the housing 22.

[0110] Since the shell 22 needs to support multiple aerosol bodies 21, the shell 22 needs to have a certain stiffness and needs to avoid being ignited by the heating element 212. Therefore, the paper material used to make the shell 22 needs to meet at least one of the following conditions:

[0111] (1) The mass per square meter of the paper material is greater than or equal to 300 g. Preferably, the mass per square meter of the paper material is greater than or equal to 350 g; or preferably, the mass per square meter of the paper material is greater than or equal to 400 g.

[0112] The ignition point of ordinary paper is usually between 130°C and 255.5°C. In the present application, the aerosol substrate has a relatively small thickness, and its preferred thickness is no more than 1mm. Therefore, the heating temperature of the aerosol substrate 211 by the heating element 212 can be reduced and the heating time of the aerosol substrate 211 by the heating element 212 can be reduced. For example, the heating temperature of the heating element 212 can be lower than 260°C or lower than 250°C. Under the conditions of the same color and the same moisture content, the greater the mass per square meter of the paper, the higher the ignition point. Therefore, appropriately increasing the mass per square meter of the paper can increase the ignition point of the paper. Therefore, the mass per square meter of the paper used to make the shell 22 can be made at least greater than 300g to prevent the shell 22 from burning when the heating element 212 heats up.

[0113] (2) The paper is white to reduce its ability to absorb heat.

[0114] (3) The paper material contains a flame retardant, so that the paper material has a higher ignition point, and can even make the ignition point of the paper material exceed the ignition point of ordinary paper.

[0115] (4) The thickness of the paper is between 400 μm and 700 μm. Preferably, the thickness of the paper is between 450 μm and 650 μm; or preferably, the thickness of the paper is between 500 μm and 600 μm, for example, the thickness of the paper may be about 555 μm.

[0116] Under the same conditions, paper with a greater thickness has better stiffness and can better support multiple aerosols. However, due to the volume limitation of the aerosol generating product, the shell has a smaller volume, so the thickness of the paper material should not exceed 700 μm.

[0117] (5) The stiffness of the paper is greater than or equal to 6 mN·m. Preferably, the stiffness of the paper is greater than or equal to 6.5 mN·m. More preferably, the stiffness of the paper is greater than or equal to 9.5 mN·m. More preferably, the stiffness of the paper is greater than or equal to 11 mN·m. For example, the stiffness of the paper may be approximately 12.3 mN·m.

[0118] (6) The paper material includes board paper, powder paper, master paper, book cover paper or card paper.

[0119] When the housing is made of paper, the aerosol-generating article may further include an airtight layer covering the surface of the housing sidewalls to prevent the aerosol in the housing from leaking through the housing sidewalls. Of course, the housing may also be made of airtight paper.

[0120] In some embodiments, reference may be made to Figure 6-Figure 8 、 Figure 10 and Figure 11 The aerosol-generating article 2 further includes a fixing member 23 for partially defining the boundaries of the airflow channel 25. The aerosol 21 is located between the fixing member 23 and the housing 22. The fixing member 23 includes a retaining portion 231 and a through-hole 232. The retaining portion 231 covers a portion of the aerosol 21 to prevent the aerosol 21 from falling off the sidewall of the housing 22, thereby maintaining the aerosol 21 on the sidewall of the housing 22. Furthermore, the fluid channel 25 and the heating element 212 in the aerosol 21 can be located on opposite sides of the aerosol substrate 211 in the aerosol 21. This allows the aerosol substrate 211 to not only face the airflow channel 25 but also be in fluid communication with the airflow channel 25 via the through-hole 232, allowing the aerosol generated by the aerosol substrate 211 to flow into the airflow channel 25 through the through-hole 232.

[0121] The area of ​​the through hole 232 can be made smaller than the area of ​​the aerosol 21, thereby preventing the aerosol 21 from passing through the through hole 232 and falling off. The shape of the through hole 232 can be different from that of the aerosol 21, and the size of the through hole 232 in a certain direction can be smaller than the size of the aerosol 21 in the same direction, thereby preventing the aerosol 21 from passing through the through hole 232 and falling off.

[0122] In such Figure 7 、 Figure 8 、 Figure 10 and Figure 11In the illustrated embodiment, the shape of the through hole 232 differs from that of the aerosol 21. The through hole 232 includes two oppositely disposed straight sides and two oppositely disposed curved sides, with the distance between the two straight sides being less than the width, length, or diameter of the aerosol 21. The curved sides can be arcs, and their diameters can be greater than or equal to the width, length, or diameter of the aerosol 21.

[0123] As an example, the fixing member 23 is configured to absorb liquid. For example, the fixing member 23 may include cotton cloth. Thus, the fixing member 23 can absorb aerosol condensation formed on its surface, absorb excess liquid in the aerosol substrate 211, and reduce aerosol condensation in the aerosol substrate 211. This can prevent the aerosol substrate 211, which subsequently generates aerosol, from getting wet, and prevent condensation from leaking out of the housing 22.

[0124] As an example, the fixing member 23 is made of paper. When the housing 22 and the fixing member 23 are both made of paper, the paper made of the two can have the same thickness, the same stiffness, the same color, the same composition and / or the same quality per square meter.

[0125] As an example, see Figure 6-Figure 8 The aerosol-generating article 2 further includes a limiting member 24 disposed between the fixing member 23 and the side wall of the housing 22. The limiting member 24 defines a limiting hole 241. At least a portion of the aerosol substrate 211 is positioned within the limiting hole 241. Preferably, the heating element 212 in the aerosol 21 corresponding to the aerosol substrate 211 is also positioned within the limiting hole 241. The limiting hole 241 is used to determine the position of the aerosol 21 on the side wall of the housing 22. A limiting member 24 may include multiple limiting holes 241, each of which may contain an aerosol substrate 211. The multiple limiting holes 241 on the limiting member 24 determine the relative positions of the multiple aerosols 21 and the distribution of the multiple aerosols 21 on the side wall of the housing 22.

[0126] The stopper 24 can be made of paper. When both the housing 22 and the stopper 24 are made of paper, the paper used to make both can have the same thickness, stiffness, color, composition, and / or mass per square meter. Of course, making the stopper of paper is optional but not mandatory.

[0127] The position-limiting member 24 may be bonded to the side wall of the housing 22 using adhesive or double-sided tape. The holding portion 231 may be bonded to the position-limiting member 24 using adhesive or double-sided tape.

[0128] Preferably, the limiting hole 241 on the limiting member 24 and the through hole 232 on the fixing member 23 are provided correspondingly, and the limiting hole 24 and the through hole 232 may share a common central axis.

[0129] When the fixing member 23, the limiting member 24 and the housing 22 are all made of paper, the preparation process of the aerosol generating article 2 may be:

[0130] First, a first paper sheet, a second paper sheet, and a third paper sheet are obtained. A limiting hole 241 is opened on the second paper sheet, making the second paper sheet a limiting member 24. A through hole 232 is opened on the third paper sheet, making the third paper sheet a fixing member 23. Positioning holes 27 can also be opened on the first paper sheet, the second paper sheet, and the third paper sheet for mechanical transmission and / or positioning alignment. Among them, the first paper sheet has the largest area.

[0131] Then, the positioning hole 27 on the limiting member 24 is aligned with the positioning hole 27 on the first paper piece, and the limiting member 24 is pasted on the first paper piece.

[0132] Then, the aerosol 21 is placed in the limiting hole 241 .

[0133] Then, the positioning hole 27 on the fixing member 23 is aligned with the positioning hole 27 on the limiting member 24, and the fixing member 23 is attached to the limiting member 24. As a result, a portion of the aerosol 21 is abutted and covered by the retaining portion 231 in the fixing member 23, so that the aerosol 21 is clamped between the fixing member 23 and the first paper sheet, and at least a portion of the aerosol substrate 211 is arranged facing the through hole 232.

[0134] Then, fold the first paper sheet so that the first paper sheet forms a shell 22 having at least three side walls. Figure 5 and Figure 10 In the embodiment shown, the housing 22 formed by folding a paper sheet has four side walls. After the housing 22 is formed, the aerosol 21 is retained on the predetermined side walls of the housing 22 .

[0135] You can refer to Figure 1-Figure 4 Some embodiments of the present application provide an aerosol-generating device 1, which includes a main body 12 and a storage box 14. The storage box 14 is disposed in the main body 12, and the main body 12 further includes an air inlet channel 16 for fluidly connecting the outside world and the storage box 14. The storage box 14 can store at least a portion of an aerosol-generating article 2. The aerosol-generating article 2 can be the aerosol-generating article 2 provided in any of the above-described embodiments, or other aerosol-generating articles 2. When the aerosol-generating article 2 is disposed in the storage box 14, outside air can enter the aerosol-generating article 2 through the air inlet channel 16, and the aerosol-generating article 2 can generate aerosol under the power provided by the power supply component in the aerosol-generating device 1.

[0136] In some embodiments, the aerosol-generating article 2 stored in the storage box 14 has a shell 22 made of paper. The hardness of the shell 22 made of paper is lower than that of a shell 22 made of plastic. Therefore, it is not convenient to achieve a sealing connection between the shell 22 and the storage box 14 and / or the main body 12 by interference fitting the shell 22 with a silicone plug having a sealing function, thereby achieving a sealed connection between the shell 22 and the storage box 14 and / or the main body 12, thereby achieving a sealed connection between the air inlet channel 16 and the paper shell 22.

[0137] Based on this, in some embodiments, reference may be made to Figure 2 The aerosol generating device 1 includes a cover assembly 13, which is configured to be operable and can expose or cover the storage box 14 based on the operation. When the cover assembly 13 covers the storage box 14, there is no squeezing or interference between the cover assembly 13 and the shell 22 of the aerosol generating product 2, and a sealed connection is formed between the cover assembly 13 and the main body 12. Therefore, when the cover assembly 13 covers the storage box, the airflow inside the storage box 14 can be prevented from convecting with the outside air through the cover assembly 13, so that the outside air mainly enters the storage box 14 through the air inlet channel 16. It should be noted that there is no extrusion or interference between the cover assembly 13 and the shell 22 of the aerosol generating product 2, including no contact between the cover assembly 13 and the shell 22 of the aerosol generating product 2, or although there is contact between the cover assembly 13 and the shell 22 of the aerosol generating product 2, the interaction force between the two is small, which is mainly used to prevent the shell 22 from shaking in the receiving box 14 and will not cause deformation of the shell 22.

[0138] Therefore, the detection accuracy of the airflow sensor provided inside the main body 12 for detecting the suction and in fluid communication with the air intake passage and / or the receiving box can be improved.

[0139] In such Figure 2-Figure 4 In the illustrated embodiment, the main body 12 includes a housing 121, and the storage box 14 is located inside the housing 121. A window 122 is defined in a sidewall of the housing 121. When the window 122 is open, the aerosol-generating article 2 can be placed in the storage box 14 or removed from the storage box 14. The aerosol-generating device 1 also includes a fourth sealing ring 19, which can be retained on the lid assembly 13, the main body 12, or the storage box 14. When the lid assembly 13 is placed on the window 122, the lid assembly 13 shields the storage box 14, and the fourth sealing ring 19 provides a seal between the lid assembly 13 and the main body 12 or the storage box 14.

[0140] In order to ensure that when the cover assembly 13 is placed on the window 122, the cover assembly 13 and the main body 12 or the storage box 14 maintain a tight fit, thereby maintaining a seal between the cover assembly 13 and the main body 12 or the storage box 14, and the cover assembly 13 can be removed by operation to expose the window 122. In some embodiments, a first magnetic member 131 is provided in the cover assembly 13 and a second magnetic member is provided in the main body 12. When the cover assembly 13 is placed on the window 122, the magnetic attraction between the first magnetic member 131 and the second magnetic member maintains a sealed connection between the cover assembly 13 and the main body 12 or the storage box 14.

[0141] The cover assembly 13 may be a flip cover, with one side of the cover assembly 13 hinged to the main body 12, so that the window 122 can be covered or exposed by flipping the cover assembly 13. Of course, the cover assembly 13 may also be a sliding cover, or the cover assembly 13 may be detachably connected to the main body 12 so that the cover assembly 13 can be removed from the housing 121.

[0142] In some embodiments, reference may be made to Figure 3 and Figure 4 The storage box 14 includes a first receiving cavity 141 for receiving at least part of the aerosol generating product 2, and also includes a receiving wall surrounding the first receiving cavity 141 and defining the circumferential side walls of the first receiving cavity 141, and a bottom wall defining the bottom boundary of the first receiving cavity 141. The bottom wall is connected to the receiving wall, and the bottom wall is arranged opposite to the opening of the storage box 14. The bottom wall is used to support the aerosol generating product 2. The aerosol generating product 2 can enter the first receiving cavity 141 from the opening of the storage box 14, and can also exit the first receiving cavity 141 from the opening of the storage box 14.

[0143] The aerosol generating device 1 further includes a third sealing ring 20, which surrounds the outer periphery of the storage wall of the storage box 14 and is positioned in close contact with the storage wall of the storage box 14. The third sealing ring 20 is positioned adjacent to the opening of the storage box 14 and elastically abuts the outer shell 121, providing a seal between the outer shell 121 and the storage wall of the storage box 14. This prevents airflow within the main body 12 from entering the first receiving cavity 141 through the opening of the storage box 14 after the cover assembly 13 blocks the window 122. The opening of the storage box 14 is positioned toward the window 122.

[0144] In some embodiments, reference may be made to Figure 3 and Figure 4The storage box 14 includes an air inlet hole 144 that fluidly connects the air inlet channel 16 and the first receiving chamber 141. The aerosol generating device 1 also includes a first sealing ring 17. The first sealing ring 17 is arranged between the storage box 14 and the main body 12 to provide a seal between the storage box 14 and the main body 12, so that the air in the air inlet channel 16 mainly enters the storage box 14, which helps to reduce the inhalation resistance.

[0145] For further information, please refer to Figure 3 and Figure 4 The storage box 14 has a second receiving chamber 142 in fluid communication with the first receiving chamber 141 , the second receiving chamber 142 is used to receive the airflow sensor, and both the first receiving chamber 141 and the second receiving chamber 142 are in fluid communication with the air inlet channel 16 through the air inlet hole 143 .

[0146] In some embodiments, reference may be made to Figure 3 and Figure 4 The aerosol generating device 1 further includes a nozzle assembly 15 and a second sealing ring 18. The storage box 14 includes an air outlet 144 for fluidly connecting the aerosol generating product 2 and the nozzle assembly 15. The second sealing ring 18 is arranged between the storage box 14 and the nozzle assembly 15 to provide a seal between the storage box 14 and the nozzle assembly 15, so that the gas in the receiving box 14 mainly enters the nozzle assembly 15 through the air outlet 144, which helps to prevent aerosol leakage and prevents the gas in the main body 12 from entering the nozzle assembly 15, thereby helping to improve the taste.

[0147] In some embodiments, reference may be made to Figure 12 The housing 22 has a generally trapezoidal cross-section. Specifically, when the aerosol-generating article 2 is stored in the storage box 14, the width of the sidewall of the housing 22 facing the window 122 is smaller than the inner width of the first storage cavity 141. This facilitates the removal of the aerosol-generating article 2 from the storage box 14 by utilizing the gap between the sidewall of the housing 22 and the storage wall of the storage box 14. Furthermore, the width of the sidewall of the housing 22 supported by the bottom wall of the storage box 14 is larger than the width of the sidewall of the housing 22 facing the window 122, thereby limiting the swaying amplitude of the aerosol-generating article 2 in the storage box 14. Preferably, the sidewall of the housing 22 supported by the bottom wall of the storage box 14 is substantially the same as the inner width of the storage box 14.

[0148] In some embodiments, the aerosol-generating article 2 further includes an extraction member 28 disposed on the outer surface of the side wall of the housing 22. The extraction member 28 includes a connecting portion 281 and an operating portion 282. The connecting portion 281 is connected to the outer surface of the housing 22, and the operating portion 282 is configured to be detachable from the outer surface of the housing 22 and to be tilted relative to the connecting portion 281 for a user to grasp. The user can remove the aerosol-generating article 2 from the storage box 14 by extracting the operating portion 282.

[0149] The extraction member 28 may be a thin plastic sheet with a relatively small thickness, or the extraction member 28 may be a thin paper sheet with a relatively small thickness.

[0150] In other embodiments, reference may be made to Figure 9 The shell 22 is made of paper, and the interior of the shell 22 contains an aerosol substrate 211 capable of generating an aerosol. The shell 22 is generally square and box-shaped, and includes a second port. The aerosol-generating article 2 also includes a sealing wall that blocks the second port. The aerosol-generating article 2 also includes a nozzle 30, which is fixed to the sealing wall 29 and is in fluid communication with the airflow channel 25. Therefore, the aerosol-generating article 2 provided in this embodiment may be different from the aerosol-generating article 2 provided in any of the above-mentioned embodiments. Of course, the aerosol-generating article 2 provided in this embodiment may also be formed by adding a sealing wall 29 and a nozzle 30 to an aerosol-generating article 2 provided in any of the above-mentioned embodiments, where the shell 22 is made of paper.

[0151] The sealing wall 29 can be made of paper, and the paper used to make the sealing wall 29 can be the same as the paper used to make the housing 22. The paper can be folded to form the square box-shaped housing 22 and the sealing wall 29 at the same time. The airtight layer can cover both the sealing wall 29 and the sidewalls of the housing 22 to prevent aerosols from leaking through the sealing wall 29 and the seam between the sealing wall 29 and the sidewalls of the housing 22. Alternatively, the sealing wall 29 can be made of an airtight plug, and the plug is hermetically connected to the sidewalls of the housing 22.

[0152] The nozzle 30 may be cylindrical or oval, and may be held by the user between the lips.

[0153] When the aerosol generating product 2 includes a nozzle 30, the aerosol generating device 1 may be without the nozzle assembly 15, and the nozzle 30 of the aerosol generating product 2 may pass through the air outlet 144 of the receiving box 14, and the receiving box 14 and the main body 12 are sealed so that the gas in the receiving box 14 but outside the aerosol generating product 2 cannot flow out of the receiving box 14.

[0154] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
