Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generation, and in particular to an aerosol generating article. BACKGROUND

[0002] An aerosol generating device is a device capable of generating aerosol for a user to inhale when an aerosol generating article is heated without being combusted. In some exemplary prior art, there is an aerosol generating article comprising a substrate, a cover plate and a tobacco sheet, the substrate is provided with a receiving groove, the tobacco sheet is received in the receiving groove, and the cover plate is coupled with the substrate to have a gap space between the two, the gap space is in fluid communication with the tobacco sheet and forms an airflow passage capable of transmitting aerosol.

[0003] The aerosol generating article needs to meet the requirements of multiple puffs of a user, and the amount of volatile substances in a tobacco sheet is limited, so that the amount of aerosol generated therefrom is insufficient to meet the requirements of the number of puffs of a user. Therefore, the tobacco sheet usually has multiple tobacco sheets, and the multiple tobacco sheets generate aerosol in sequence. The aerosol generated by each tobacco sheet needs to be transmitted to be inhaled by a user, resulting in that the more the tobacco sheets, the larger the space of the airflow passage, and the worse the taste of each puff. SUMMARY

[0004] The purpose of the present application is to provide an aerosol generating article capable of significantly improving the proportion of aerosol in airflow.

[0005] At least one embodiment of the present application provides an aerosol generating article, which comprises:

[0007] A housing has an airflow passage inside; the housing comprises a first side wall and a second side wall arranged non-coplanarly, a plurality of the aerosol bodies are contained in the housing, and part of the aerosol bodies are retained on the first side wall and part of the aerosol bodies are retained on the second side wall; and a plurality of the aerosol substrates are in fluid communication with the airflow passage.

[0008] As an example, the airflow passage has a substantially rectangular cross section and satisfies at least one of the following conditions:

[0009] The width of the airflow passage is less than 15 mm; or

[0010] The height of the airflow passage is less than 3 mm; or

[0011] The difference between the width of the airflow passage and the width of the aerosol substrate is less than 5 mm; or

[0012] A difference between a width of the airflow passage and a width of the aerosol substrate is less than 1 / 2 of the width of the aerosol substrate.

[0013] As one example, the first side wall and the second side wall are oppositely arranged.

[0015] The housing includes a first port that is open, the first port being configured to allow ambient air to enter the airflow passage; or

[0016] The housing includes a second port that is open, the second port being configured to allow gas in the airflow passage to flow out of the housing.

[0017] As one example, the housing is made of paper.

[0018] As one example, the housing is substantially a square box shape, and the housing includes a second port, and the aerosol generating article further includes a sealing wall that seals the second port; the aerosol generating article further includes a mouthpiece fixed to the sealing wall and in fluid communication with the airflow passage.

[0019] As one example, the aerosol generating article further includes a gas impermeable layer arranged to cover a surface of the housing side wall; or

[0020] The housing is made of paper that is capable of preventing gas permeation.

[0021] As one example, the aerosol generating article includes a heating element arranged to correspond to the aerosol body, the heating element contacting the aerosol substrate of the aerosol body.

[0022] As one example, the heating element includes a fixing portion at least partially embedded in the first side wall and / or the second side wall.

[0023] As one example, the aerosol generating article further includes a fixing member for defining a boundary of the airflow passage portion, the aerosol body being located between the fixing member and the housing;

[0024] The fixing member includes a holding portion and a through hole, the holding portion covering a portion of the aerosol body to hold the aerosol body on a side wall of the housing, and the aerosol substrate being in fluid communication with the airflow passage through the through hole.

[0025] As an example, the fastener is configured to absorb liquid.

[0026] As an example, the aerosol-generating article further includes a limiting member disposed between the fixing member and the side wall of the housing, the limiting member having a limiting hole, and at least a portion of the aerosol substrate being located in the limiting hole.

[0027] As an example, the limiting member is adhered to the side wall of the housing; and / or

The plurality of aerosols are spaced apart within the shell, with some aerosols held on the first sidewall and some on the second sidewall. All aerosol substrates are in fluid communication with the airflow channel. Therefore, the plurality of aerosols can not only use the same airflow channel to transport aerosols, but also communicate with the airflow channel in different directions. This not only increases the distribution density of aerosols within the limited space of the shell, but also allows the plurality of aerosols to fully occupy the internal space of the shell, which helps to reduce the space of the airflow channel and increases the proportion of aerosols in the airflow during each inhalation.

[0047] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0048] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be intervening elements. When an element is referred to as being "connected to" another element, it can be directly connected to the other element, or there may be one or more intervening elements. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0049] Please refer to Figures 1-9 Some embodiments of this application provide an aerosol generating article 2, which can interact with an aerosol generating device 1 and can generate aerosols under the power provided by the aerosol generating device 1.

[0050] The aerosol generating article 1 includes a plurality of aerosol bodies 21 spaced apart from each other and a shell 22 for containing the plurality of aerosol bodies 21, wherein the aerosol body 21 includes an aerosol substrate 211, which can generate aerosols when heated.

[0051] As used in this article, the term "multiple" refers to two or more.

[0052] As used herein, the term "aerosol substrate" refers to a substrate capable of releasing volatile substances to form an inhalable aerosol. The aerosol substrate may include tobacco-containing materials containing volatile tobacco flavor compounds that are released from the substrate upon heating. Specifically, the aerosol substrate may be a tobacco-containing aerosol substrate, preferably a solid tobacco-containing aerosol substrate. Alternatively, the aerosol substrate may include non-tobacco materials. The aerosol substrate may also include an aerosol forming agent. Examples of suitable aerosol forming agents are glycerol and propylene glycol.

[0053] If desired, 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, which, for example, contain additional tobacco or non-tobacco volatile flavor compounds and can melt during heating of the solid aerosol substrate.

[0054] The aerosol substrate 211 can be generally disc-shaped or circular. The aerosol substrate 211 can also be generally rectangular.

[0055] Preferably, the aerosol substrate is a tobacco sheet comprising tobacco material, fibers, a binder, and an aerosol forming agent. Preferably, the tobacco sheet is a cast leaf. A cast leaf is a form of reconstituted tobacco formed from a pulp comprising tobacco particles, fiber particles, an aerosol forming agent, a binder, and, for example, a flavoring agent.

[0056] The tobacco particles may be in the form of tobacco dust having particles of about 30 micrometers to 250 micrometers, preferably about 30 micrometers to 80 micrometers or 100 micrometers to 250 micrometers, depending on the desired sheet thickness and the casting gap, wherein the casting gap typically defines the sheet thickness.

[0057] The thickness of the aerosol substrate 211 can be in the range of 0.2 mm to 6 mm, preferably between 0.5 mm and 4 mm, and more preferably between 0.2 mm and 1 mm. For example, the thickness of the aerosol substrate 211 can be about 0.4 mm.

[0058] The fiber pellets may contain tobacco stem material, stalks, or other tobacco plant material, as well as other cellulose-based fibers, such as wood fibers with low lignin content. The fiber pellets can be selected based on the need for sufficient tensile strength to produce sheets and a low inclusion rate, for example, between about 2% and 15%. Alternatively, fibers such as plant fibers may be used with the aforementioned fiber pellets, or, alternatively, bamboo may be included.

[0059] In some embodiments, the aerosol generating article 2 further includes a heating element 212, which is used to release heat to heat the aerosol substrate 211 so that the aerosol substrate 211 generates aerosol.

[0060] There can be multiple heating elements 212. Multiple heating elements 212 can be arranged one-to-one with multiple aerosols 21, so that each heating element 212 mainly provides heat to one of the aerosols 21 to generate aerosols.

[0061] The heating element 212 can be a component of the aerosol 21, that is, at least one aerosol 21 includes an aerosol substrate 211 and a heating element 212 for heating the aerosol substrate 211.

[0062] The heating element 212 can be in direct contact with the corresponding aerosol substrate 211. Based on this, as an example, the aerosol substrate 211 is bonded to the surface of the heating element 212 using an adhesive. As an example, the aerosol substrate 211 is made into a slurry, coated onto the surface of the heating element 212, and after drying, forms an aerosol substrate coating layer on the surface of the heating element 212. As an example, the heating element 212 is fixed to one side wall of the housing 22, and the aerosol generating article 2 also includes a fixing member 23, which interferes with the aerosol substrate 211, causing the aerosol substrate 211 to contact the heating element 212. As an example, at least a portion of the heating element 212 is disposed inside the aerosol substrate 211.

[0063] The heating element 212 can be spaced apart from the corresponding aerosol substrate 211. For example, the heating element 212 can be disposed on the outer surface of the housing 22 or outside the housing 22, while the aerosol substrate 211 can be disposed inside the housing 22.

[0064] In some embodiments, the heating element 212 includes a sensor, and as used herein, the term "sensor" refers to a material capable of converting electromagnetic energy into heat. Eddy currents induced in the sensor when it is located within a changing electromagnetic field cause heating of the sensor. In such embodiments, the aerosol generating apparatus 1 may include a magnetic field generator 11. The magnetic field generator 11 generates a changing magnetic field to heat the sensor located within the changing magnetic field. In use, the sensor is located within the changing magnetic field generated by the magnetic field generator 11. The magnetic field generator 11 is electrically connected to a power supply assembly in the aerosol generating apparatus 1, which provides current to the magnetic field generator 11 to generate the changing magnetic field. The magnetic field generator 11 may include one or more induction coils for generating the changing magnetic field. In some embodiments, the aerosol generating apparatus 1 is capable of generating a changing 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 apparatus is capable of generating a magnetic field with a field strength (H field) varying between 1 and 5 kA / m, for example between 2 kA / m and 3 kA / m, such as about 2.5 kA / m.

[0065] The receptor may include a metal or carbon. In some embodiments, the receptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel, or stainless steel. In some embodiments, the receptor includes a nickel-iron alloy. In some embodiments, the receptor includes 400 series stainless steel, which includes grade 410, 420, or 430 stainless steel.

[0066] In some embodiments, the heating element 212 comprises a resistive material or an infrared coating. The resistive material generates Joule heat when it receives power from the power supply component. The infrared coating emits infrared radiation when it receives power from the power supply component.

[0067] In some embodiments, the heating element 212 is generally disc-shaped or circular. In some embodiments, the heating element 212 is generally rectangular. In some embodiments, the heating element 212 has a substantially the same shape as the aerosol substrate 211.

[0068] Multiple aerosols 21 are spaced apart from each other. Therefore, the aerosol substrates 211 in different aerosols 21 are independent of each other and can independently generate aerosols; the heating elements 212 corresponding to different aerosols 21 can also be independent of each other and can generate heat independently. Furthermore, before the aerosols 21 are housed in the housing 22, the multiple aerosols 21 can already be independent of each other.

[0069] In some embodiments, reference may be made to Figure 5 and Figure 6After multiple independent aerosols 21 are contained in the housing 22, they can continue to remain independent of each other in the housing 22, so that at least two aerosols 21 are arranged at intervals within the housing 22.

[0070] In some embodiments, reference may be made to Figure 5 , Figure 6 The housing 22 has an airflow channel 25. Aerosols 21 can be uniformly held on the sidewalls of the housing 22, and multiple aerosol substrates 211 can be in fluid communication with the same or different airflow channels 25. By configuring the housing 22 so that multiple aerosols 21 contained within it share a single airflow channel 25 for aerosol transmission, the housing 22 can have one air inlet and one air outlet, simplifying and stabilizing its structure.

[0071] If all aerosol substrates are placed on the same side of the airflow channel: if multiple aerosol substrates are arranged in a single row, the airflow channel will have a large length and a large volume, resulting in a small proportion of aerosol in the airflow output from the channel. For example, if six aerosol substrates are arranged in a row along the airflow channel, assuming that the airflow channel space corresponding to one aerosol substrate has one volume, then the airflow channel in the shell will have at least six volumes. However, since only one aerosol substrate can generate aerosol at any given time, the proportion of aerosol in the airflow output from the airflow channel when the user inhales will be less than 1 / 6, resulting in a bland taste. On the other hand, if multiple aerosol substrates are arranged in multiple rows along the width direction, the airflow channel will have a larger width. The more rows there are, the wider the airflow channel becomes, and the larger the volume of the airflow channel, resulting in a smaller proportion of aerosol in the airflow output from the airflow channel.

[0072] You can refer to Figure 5 and Figure 6 In this application, the housing 22 includes a first sidewall 221 and a second sidewall 222 that are not coplanar. A portion of the aerosols 21 are held on the first sidewall 221, and a portion of the aerosols 21 are held 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 at least two aerosol substrates 211 to be in fluid communication with the airflow channel 25 in different directions. This not only increases the distribution density of the aerosols 21 within the limited space of the housing 22, allowing the housing 22 to accommodate many more aerosols 21 without doubling the volume of the airflow channel 25, but also makes the aerosols 21 more concentrated, thereby reducing the volume of the housing 22 and the airflow channel 25.

[0073] Preferred options can be referenced. Figure 5 The airflow channel 25 has a generally rectangular cross-section, which 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 another 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 another 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, this difference can be approximately 3.6 mm. It should be noted that when the aerosol substrate 211 is approximately disc-shaped or circular, the width of the aerosol substrate 211 is approximately the diameter of the disc or circle; when the aerosol substrate 211 is approximately disc-shaped or rectangular, the width of the aerosol substrate 211 is approximately 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 half the width of the aerosol substrate 211. In one specific embodiment, the width of the aerosol substrate 211 is approximately 8.5 mm, and the width w of the airflow channel 25 is approximately 12 mm.

[0074] More preferably, the cross-section of the airflow channel 25 is approximately rectangular to further reduce the cross-sectional area of ​​the airflow channel.

[0075] It should be noted that in other embodiments, the cross-section of the airflow channel 25 may also be a non-circular shape.

[0076] The aerosol 21 can be generally sheet-like, and the first sidewall 221 can have a planar inner surface. Therefore, the first sidewall 221 can better hold the aerosol 21 and facilitates the assembly of the aerosol 21 onto the first sidewall 221. The second sidewall 222 can also have a planar inner surface to better hold the aerosol 21.

[0077] Furthermore, the first sidewall 221 can be generally flat, and the second sidewall 222 can also be generally flat.

[0078] The first sidewall 221 and the second sidewall 222 can be two adjacent sidewalls on the housing 22. For example, the cross-section of the housing 22 can be approximately triangular, so the housing 22 also includes a third sidewall, which can also hold a portion of the aerosols 21 among the multiple aerosols 21.

[0079] The first sidewall 221 and the second sidewall 222 can be two sidewalls spaced apart on the housing 22, preferably with the first sidewall 221 and the second sidewall 222 facing each other. For example, the cross-section of the housing 22 can be approximately quadrilateral. Based on this, the housing 22 also includes a third sidewall and a fourth sidewall, with the first sidewall 221 facing the second sidewall 222 and the third sidewall facing the fourth sidewall. The third sidewall and / or the fourth sidewall can also hold a portion of the multiple aerosols 21. To reduce the height of the housing 22, it is preferable that the third and fourth sidewalls are left unused, with no aerosols 21 disposed on them, and 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 approximately flat, making the housing 22 approximately box-shaped.

[0080] When the first sidewall 221 and the second sidewall 222 are arranged opposite each other, the distance between the first sidewall 221 and the second sidewall 222 in the length direction of the housing 22 can remain substantially constant. For example, both the first sidewall 221 and the second sidewall 222 have generally planar inner surfaces, and the inner surfaces of the first sidewall 221 and the second sidewall 222 are parallel to each other. In other embodiments, when the first sidewall 221 and the second sidewall 222 are arranged opposite each other, the distance between the first sidewall 221 and the second sidewall 222 in the length direction of the housing 22 can gradually increase or decrease.

[0081] In some embodiments, the housing 22 has a plurality of sidewalls, wherein at least one sidewall is generally rectangular, such that the housing 22 has at least one generally rectangular face. In other embodiments, at least one sidewall in the housing 22 may be generally trapezoidal, such that the housing 22 has at least one generally trapezoidal face.

[0082] It should be noted that the housing 22 may also have arc-shaped sidewalls, thus having an arc-shaped surface. The housing 22 may also be generally cylindrical, thus having a circular surface.

[0083] In some embodiments, the housing 22 includes an open first port configured to allow outside air to enter the airflow channel 25. A first sidewall 221 and a second sidewall 222 may define a portion of the boundary of the first port. To prevent leakage of condensate formed by aerosols in the airflow channel 25 from the first port, the aerosol generating article 2 may further include a permeable wall 26 that allows airflow through it, disposed on the first port. At least a portion of the permeable wall 26 may be located within the first port, connecting the inner surfaces of the first sidewall 221 and the second sidewall 222, and at least a portion may be located outside the first port, shielding the first port and connecting the ends of the first sidewall 221 and the second sidewall 222. As an example, the permeable wall 26 includes a sheet of paper with a plurality of perforations. As an example, the permeable wall 26 includes a breathable fiber bundle, such as breathable cotton, cellulose acetate, a filter element, or cotton cloth, thereby enabling the permeable wall 26 to absorb liquid.

[0084] In some embodiments, housing 22 includes an open second port configured to allow gas in airflow passage 25 to exit housing 22. First sidewall 221 and second sidewall 222 may define a portion of the boundary of the second port.

[0085] The first port and the second port can be located on opposite sides of the housing 22.

[0086] After the aerosol 21 is contained in the housing 22, the aerosol substrate 211 can be positioned close to the airflow channel 25 to reduce the travel distance of the aerosol generated by the aerosol substrate 211 into the airflow channel 25. Based on this, the aerosol substrate 211 can be located between the corresponding heating element 212 and the airflow channel 25.

[0087] Alternatively, after the aerosol 21 is contained in the housing 22, the heating element 212 can be positioned close to the airflow channel 25 to prevent aerosols generated by other aerosol substrates 211 from condensing on their corresponding aerosol substrates 211, and / or to allow the condensate condensed thereon to evaporate when heated. Based on this, the heating element 212 can be located between the corresponding aerosol substrate 211 and the airflow channel 25.

[0088] In some embodiments, at least a portion of the housing 22 is injection molded from plastic. The plastic may include PAEK-based materials, PI materials, or PBI materials. PAEK-based materials include PEEK, PEKK, PEKEKK, or PEK materials.

[0089] In some embodiments, the housing 22 is made of paper. Paper is not only cheaper than plastic, but also more environmentally friendly.

[0090] In some embodiments, the housing 22 is formed by folding a sheet of paper. The planar paper can be folded into a three-dimensional shape with at least three sidewalls, for example, the housing 22 is generally box-shaped with a quadrilateral cross-section, or for example, the housing 22 is generally triangular prism-shaped with a generally triangular cross-section.

[0091] For example, you can refer to Figure 5 , Figure 7 and Figure 8 One sidewall of the housing 22 includes a first connecting edge 223 and a second connecting edge 224 that are at least partially overlapping, located on opposite sides of the unfolded paper material forming the housing 22. The first connecting edge 223 and the second connecting edge 224 can be bonded together using adhesive or double-sided tape to prevent the inner side of either the first connecting edge 223 or the second connecting edge 224 from warping inwards. The first connecting edge 223 and the second connecting edge 224 may have approximately the same height and length, but are not limited thereto.

[0092] For example, the paper materials used to make the housing 22 can overlap each other without edges after the housing 22 is made. For instance, the end of one side wall of the housing 22 abuts against the inner surface of the adjacent side wall, and the outer surfaces of the two side walls are covered and connected by tape, which can cover the seam between the two side walls, thereby sealing the seam and preventing aerosol from leaking through the seam.

[0093] In some embodiments, the housing 22 is formed by splicing together multiple sheets of paper. At least some of the multiple sheets of paper may be flat; or, at least some of the multiple sheets of paper may be folded with corners.

[0094] You can refer to Figure 7 and Figure 8 Before folding or splicing the paper to form the shell 22, the aerosol 21 can be placed in the appropriate part of the paper, and then the paper can be folded or spliced. After the shell 22 is formed, each aerosol 21 is located on the corresponding side wall of the shell 22.

[0095] As an example, the heating element 212 includes a fixing portion, which is at least partially embedded in the side wall of the housing 22 for fixation, for example, embedded in the first side wall 221 and / or the second side wall 222. The fixing portion can be embedded in the side wall by piercing the paper, or a hole can be pre-drilled in the paper housing 22, and then at least partially embedded in the hole. It should be noted that including the fixing portion in the heating element 212 is optional and not mandatory; other methods can also be used to hold the heating element 212 on the side wall of the housing 22.

[0096] Since the housing 22 needs to support multiple aerosols 21, it requires both a certain degree of rigidity and protection from ignition by the heating element 212. Therefore, the paper material used to manufacture the housing 22 must meet at least one of the following conditions:

[0097] (1) The paper material has a mass of 300g or more per square meter. Preferably, the paper material has a mass of 350g or more per square meter; or preferably, the paper material has a mass of 400g or more per square meter.

[0098] The ignition point of ordinary paper is typically between 130°C and 255.5°C. In this application, the aerosol substrate has a relatively small thickness, preferably no more than 1 mm. Therefore, the heating temperature of the aerosol substrate 211 by the heating element 212 and the heating time of the aerosol substrate 211 by the heating element 212 can be reduced, for example, so that the heating temperature of the heating element 212 can be lower than 260°C or lower than 250°C. With the same color and moisture content, the greater the mass per square meter of paper, the higher the ignition point. Therefore, appropriately increasing the mass per square meter of paper can increase the ignition point of the paper. Thus, the mass per square meter of paper used to make the shell 22 can be at least greater than 300 g to prevent the shell 22 from burning when the heating element 212 heats up.

[0099] (2) The paper is white to reduce its heat absorption capacity.

[0100] (3) The paper contains flame retardants to give it a higher ignition point, and even to make it higher than that of ordinary paper.

[0101] (4) The thickness of the paper is between 400μm and 700μm. Preferably, the thickness of the paper is between 450μm and 650μm; or preferably, the thickness of the paper is between 500μm and 600μm, for example, the thickness of the paper can be about 555μm.

[0102] Under the same conditions, thicker paper has better stiffness and can better support multiple aerosols. However, due to the volume limitations of the aerosol-generated product, the shell has a small volume, so the thickness of the paper should not exceed 700 μm.

[0103] (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. Even more preferably, the stiffness of the paper is greater than or equal to 11 mN·m, for example, the stiffness of the paper can be about 12.3 mN·m.

[0104] (6) The paper material includes cardboard, powdered paper, printing paper, book cover paper or card stock.

[0105] When the shell is made of paper, the aerosol-generating article may also include an impermeable layer that covers the surface of the shell's sidewalls to prevent aerosols inside the shell from leaking through the sidewalls. Of course, the shell can also be made of an impermeable paper material.

[0106] In some embodiments, reference may be made to Figures 6-8 The aerosol generating article 2 also includes a fixing member 23 for defining a portion of the boundary of the airflow channel 25, with the aerosol body 21 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 body 21 to prevent the aerosol body 21 from falling off the side wall of the housing 22, thus allowing the aerosol body 21 to be retained on the side wall of the housing 22. Furthermore, the heating element 212 in the fluid channel 25 and the aerosol body 21 can be located on opposite sides of the aerosol substrate 211 in the aerosol body 21, so that the aerosol substrate 211 can not only face the airflow channel 25, but also be fluidly connected to the airflow channel 25 through 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.

[0107] The area of ​​the through hole 232 can be smaller than the area of ​​the aerosol 21, thereby preventing the aerosol 21 from falling through the through hole 232. The shape of the through hole 232 can be different from the shape 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 that direction, thereby preventing the aerosol 21 from falling through the through hole 232.

[0108] In such Figure 7 and Figure 8 In the illustrated embodiment, the shape of the through-hole 232 is different from the shape of the aerosol 21. The through-hole 232 includes two oppositely arranged straight sides and two oppositely arranged arcuate sides. The distance between the two straight sides is less than the width, length, or diameter of the aerosol 21. The arcuate sides can be arcs, and their diameter can be greater than or equal to the width, length, or diameter of the aerosol 21.

[0109] As an example, the fastener 23 is configured to absorb liquid; for example, the fastener 23 may include a cloth. Thus, the fastener 23 can absorb aerosol condensate formed on its surface, and can also absorb excess liquid in the aerosol substrate 211 and reduce aerosol condensation in the aerosol substrate 211, preventing the aerosol substrate 211 from becoming damp after aerosol generation, and preventing condensate leakage from the housing 22.

[0110] As an example, fastener 23 is made of paper. When both housing 22 and fastener 23 are made of paper, the paper used to make them can have the same thickness, the same stiffness, the same color, the same composition, and / or the same mass per square meter. Of course, it is optional, not mandatory, for fastener 23 to be made of paper.

[0111] As an example, you can refer to Figures 6-8 The aerosol generating article 2 also includes a limiting member 24 disposed between the fixing member 23 and the side wall of the housing 22. The limiting member 24 has limiting holes 241, and at least a portion of the aerosol substrate 211 is located in the limiting hole 241. Preferably, the heating element 212 in the aerosol body 21 corresponding to the aerosol substrate 211 is also disposed in the limiting hole 241. The limiting hole 241 is used to determine the position of the aerosol body 21 on the side wall of the housing 22. A limiting member 24 may have multiple limiting holes 241, and each limiting hole 241 may contain one aerosol substrate 211. The relative positions between multiple aerosol bodies 21 and the distribution position of the multiple aerosol bodies 21 on the side wall of the housing 22 are determined by the multiple limiting holes 241 on the limiting member 24.

[0112] The limiting member 24 can be made of paper. When both the housing 22 and the limiting member 24 are made of paper, the paper used to make them can have the same thickness, the same stiffness, the same color, the same composition, and / or the same mass per square meter. Of course, making the limiting member of paper is optional, not mandatory.

[0113] The limiting member 24 can be adhered to the side wall of the housing 22 using adhesives or double-sided tape. The retaining part 231 can be adhered to the limiting member 24 using adhesives or double-sided tape.

[0114] The limiting hole 241 on the preferred limiting member 24 and the through hole 232 on the fixing member 23 are respectively provided, and the limiting hole 24 and the through hole 232 can share the same central axis.

[0115] When the fixing member 23, the limiting member 24, and the shell 22 are all made of paper, the preparation process of the aerosol-generated product 2 can be as follows:

[0116] First, a first paper piece, a second paper piece, and a third paper piece are obtained. A limiting hole 241 is made on the second paper piece, making the second paper piece a limiting member 24. A through hole 232 is made on the third paper piece, making the third paper piece a fixing member 23. Positioning holes 27 can also be made on the first paper piece, the second paper piece, and the third paper piece for mechanical transmission and / or positioning alignment. Among them, the first paper piece has the largest area.

[0117] Then, align the positioning hole 27 on the limiting member 24 with the positioning hole 27 on the first paper piece, and attach the limiting member 24 to the first paper piece.

[0118] Then, the aerosol 21 is placed in the limiting hole 241.

[0119] Next, align the positioning holes 27 on the fixing member 23 and the positioning holes 27 on the limiting member 24, and attach the fixing member 23 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, thereby clamping the aerosol 21 between the fixing member 23 and the first paper sheet, and at least a portion of the aerosol substrate 211 is disposed facing the through hole 232.

[0120] Then, the first piece of paper is folded to form a shell 22 with at least three sidewalls. (As shown in the image) Figure 5 In the illustrated embodiment, the shell 22 formed by folded paper has four sidewalls. After the shell 22 is formed, the aerosol 21 is held on the predetermined sidewalls of the shell 22.

[0121] You can refer to Figures 1-4 Some embodiments of this application provide an aerosol generating device 1, which includes a main body 12 and a receiving box 14. The receiving box 14 is disposed in the main body 12, and the main body 12 also has an air inlet channel 16 that fluidly communicates with the outside world and the receiving box 14. The receiving box 14 can hold at least a portion of the aerosol generating product 2, which can be the aerosol generating product 2 provided in any of the above embodiments, or other aerosol generating products 2. When the aerosol generating product 2 is disposed in the receiving box 14, outside air can enter the aerosol generating product 2 through the air inlet channel 16, and under the power provided by the power supply component in the aerosol generating device 1, the aerosol generating product 2 can generate aerosols.

[0122] In some embodiments, the aerosol generating article 2 housed in the storage box 14 has a shell 22 made of paper. The hardness of the paper shell 22 is less than that of the plastic shell 22, so it is not convenient to achieve a sealed connection between the paper shell 22 and the storage box 14 and / or the main body 12 by interference fit between the paper shell 22 and the silicone plug with a sealing function, thereby achieving a sealed connection between the air intake channel 16 and the paper shell 22.

[0123] Based on this, in some embodiments, reference can be made to Figure 2The aerosol generating device 1 includes a cover assembly 13, which is configured to be operable and, based on this operation, can expose or cover the storage box 14. When the cover assembly 13 covers the storage box 14, there is no compression or interference between the cover assembly 13 and the shell 22 of the aerosol generating article 2, and a sealing connection is formed between the cover assembly 13 and the main body 12. Thus, when the cover assembly 13 covers the storage box, it can prevent the airflow inside the storage box 14 from convection with the outside air through the cover assembly 13, so that the outside air mainly enters the storage box 14 through the air intake channel 16. It should be noted that there is no compression or interference between the cover assembly 13 and the shell 22 of the aerosol generating product 2. This includes 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. This is mainly used to prevent the shell 22 from shaking in the receiving box 14 and will not cause deformation of the shell 22.

[0124] Therefore, the detection accuracy of the airflow sensor, which is located inside the main body 12 and is in fluid communication with the air intake channel and / or the storage box 14 for detecting suction, can be improved.

[0125] In such Figures 2-4 In the illustrated embodiment, the main body 12 includes a housing 121, and a storage box 14 is located inside the housing 121. A window 122 is opened on the side wall of the housing 121. When the window 122 is open, the aerosol generating product 2 can be placed in the storage box 14, or the aerosol generating product 2 can be removed from the storage box 14. The aerosol generating device 1 also includes a fourth sealing ring 19. The fourth sealing ring 19 can be held on the cover assembly 13, or on the main body 12, or on the storage box 14. When the cover assembly 13 is placed over the window 122, the cover assembly 13 covers the storage box 14, and the fourth sealing ring 19 provides a seal between the cover assembly 13 and the main body 12 or the storage box 14.

[0126] To ensure a tight fit between the cover assembly 13 and the main body 12 or storage box 14 when the cover assembly 13 is placed over the window 122, thus maintaining a seal between them, and to allow the window 122 to be exposed by removing the cover assembly 13, in some embodiments, the cover assembly 13 is provided with a first magnetic element 131, and the main body 12 is provided with a second magnetic element. When the cover assembly 13 is placed over the window 122, the magnetic attraction between the first magnetic element 131 and the second magnetic element maintains a sealed connection between the cover assembly 13 and the main body 12 or storage box 14.

[0127] The cover assembly 13 can 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 can also be a sliding cover, or the cover assembly 13 can be detachably connected to the main body 12, so that the cover assembly 13 can be removed from the housing 121.

[0128] 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 a portion of the aerosol generating article 2, a receiving wall surrounding the first receiving cavity 141 and defining the circumferential sidewalls 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 is disposed opposite to the opening of the storage box 14. The bottom wall is used to support the aerosol generating article 2. The aerosol generating article 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.

[0129] The aerosol generating device 1 also includes a third sealing ring 20, which surrounds the outer periphery of the storage wall of the storage box 14 and is disposed 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 against the outer shell 121, providing a seal between the outer shell 121 and the storage wall of the storage box 14 to prevent airflow inside 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 faces the window 122.

[0130] In some embodiments, reference may be made to Figure 3 and Figure 4 The storage box 14 includes an air inlet 144 that fluidly connects the air inlet channel 16 and the first receiving cavity 141. The aerosol generating device 1 also includes a first sealing ring 17, which is disposed 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 suction resistance.

[0131] For further details, please refer to Figure 3 and Figure 4 The storage box 14 has a second receiving cavity 142 that is in fluid communication with the first receiving cavity 141. The second receiving cavity 142 is used to receive the airflow sensor, and both the first receiving cavity 141 and the second receiving cavity 142 are in fluid communication with the air intake channel 16 through the air intake hole 143.

[0132] In some embodiments, reference may be made to Figure 3 and Figure 4The aerosol generating device 1 also includes a nozzle assembly 15 and a second sealing ring 18. The receiving box 14 includes an air outlet 144 that fluidly communicates with the aerosol generating product 2 and the nozzle assembly 15. The second sealing ring 18 is disposed between the receiving box 14 and the nozzle assembly 15 to provide a seal between the receiving 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. This helps to prevent aerosol leakage and also prevents the gas in the main body 12 from entering the nozzle assembly 15, thereby helping to improve the taste.

[0133] In some embodiments, the housing 22 has a generally trapezoidal cross-section. Specifically, when the aerosol-generating article 2 is housed 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, thereby allowing the aerosol-generating article 2 to be easily removed from the storage box 14 using the gap between the sidewall of the housing 22 and the storage wall of the storage box 14. Simultaneously, the width of the sidewall of the housing 22 that is supported by the bottom wall of the storage box 14 is greater than the width of the sidewall of the housing 22 facing the window 122, thereby limiting the amplitude of swaying of the aerosol-generating article 2 within the storage box 14. Preferably, the sidewall of the housing 22 that is supported by the bottom wall of the storage box 14 is substantially the same as the inner width of the storage box 14.

[0134] In some embodiments, the aerosol generating article 2 further includes an extraction member 28 disposed on the outer surface of the sidewall 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 detach from the outer surface of the housing 22 and be able to be flipped relative to the connecting portion 281 for a user to grip. The user can remove the aerosol generating article 2 from the storage box 14 by extracting the operating portion 282.

[0135] The extraction component 28 can be a thin plastic sheet or a thin paper sheet.

[0136] In other embodiments, reference may be made to Figure 9 The housing 22 is made of paper, and its interior contains an aerosol substrate 211 capable of generating aerosols. The housing 22 is generally 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 further includes a nozzle 30, which is fixed to the sealing wall 29 and fluidly communicates with the airflow channel 25. Therefore, the aerosol generating article 2 provided in this embodiment can differ from the aerosol generating article 2 provided in any of the above embodiments. Alternatively, the aerosol generating article 2 provided in this embodiment can be formed by adding a sealing wall 29 and a nozzle 30 to the aerosol generating article 2 with a paper-based housing 22 provided in any of the above embodiments.

[0137] 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 housing 22 can be formed into a box shape by folding the paper, thus simultaneously forming the sealing wall 29. An airtight layer can cover both the sealing wall 29 and the sidewalls of the housing 22 to prevent aerosol leakage 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 this plug can be sealed to the sidewall of the housing 22.

[0138] The mouthpiece 30 can be cylindrical or oval, allowing the user to hold it in their lips.

[0139] When the aerosol generating article 2 includes a nozzle 30, the aerosol generating device 1 may be without the nozzle assembly 15. The nozzle 30 of the aerosol generating article 2 can pass through the air outlet 144 of the receiving box 14, and the receiving box 14 is sealed to the main body 12, so that the gas inside the receiving box 14 but outside the aerosol generating article 2 cannot flow out of the receiving box 14.

[0140] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
