Detailed Description of the Invention

[0028] The present application will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings. Similar elements in different embodiments are labeled with related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0029] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0030] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0031] Regarding the problem in the related art that the aerosol-generating article of the aerosol-generating article generates residues after heating, and the residues accumulate in the heating device and contaminate the device body. In the present application, by horizontally arranging the first inductive heating element at one end face of the smoke-generating section, the contact area between the first inductive heating element and the smoke-generating section is increased, and the heating effect is better. When heating is used, while the first inductive heating element heats the smoke-generating section, it can also prevent the substances in the smoke-generating section from leaking out of the aerosol-generating article, and can achieve the effect of significantly reducing residues.

[0032] In one embodiment, as Figure 1 shown, there is provided an aerosol-generating article, including a cylindrical housing 11, a smoke-generating section 12, a heating member 13, etc.

[0033] Among them, the aerosol-generating article has opposite first end 111 and second end 112. The first end 111 can be the proximal lip end, that is, the first end 111 is the end that the user sucks when sucking; the second end 112 can be the distal lip end, that is, the second end 112 is the end away from the user's sucking.

[0034] The aerosol generating section 12 is disposed within the housing 11. When the aerosol generating article is heated, the aerosol forming material within the aerosol generating section 12 is heated to generate an aerosol for the user to inhale.

[0035] The heating member 13 includes a heating element, and the heating element includes a first inductive heating element 131, which is adhesively disposed on the end face of the aerosol generating section 12 near the second end 112. The edge of the first inductive heating element 131 is hermetically connected to the inner wall of the housing 11, so that the first inductive heating element 131 hermetically seals one side of the aerosol generating section 12 near the second end 112. Using the first inductive heating element 131 as a seal to block one side of the housing 11 at the second end 112, so that the aerosol can only flow in the direction of the first end 111; at the same time, blocking the substances in the aerosol generating section 12 from leaking out of the aerosol generating article can achieve the effect of significantly reducing residues.

[0036] Further, a through air inlet hole 113 is provided on the side wall of the housing 11 from the heating member 13 to the first end 111 to introduce external air flow and carry out the aerosol generated by the aerosol generating section 12.

[0037] During use, by placing the aerosol generating article in a heating device, the heating device has a magnetic field generator, which can be, for example, an inductive heating coil. The magnetic field generator generates a magnetic field to heat the first inductive heating element 131. The heat generated by the first inductive heating element 131 is transferred to the aerosol generating section 12 to heat the aerosol generating section 12 to generate an aerosol. When the user inhales, the external air flow enters the housing 11 through the air inlet hole 113 to carry out the aerosol.

[0038] By the first inductive heating element 131 being in contact with the end face of the aerosol generating section 12 near the second end 112, during heating, the entire end face of the aerosol generating section 12 can be directly heated, and the middle and the periphery of the aerosol generating section 12 can be heated simultaneously, without the problem that the peripheral heat is insufficient to generate an aerosol, having the advantage of good heating effect. And, the first inductive heating element 131 is used to seal one side of the aerosol generating section 12 near the second end 112, and the air flow is introduced through the air inlet hole 113 provided on the side wall to carry out the aerosol generated by heating.

[0039] In some embodiments, the first inductive heating element 131 can be a solid cylinder, hermetically sealing the end face of the housing 11 or sealing the inside of the end face of the housing 11.

[0040] In one embodiment, the aerosol-generating article further includes a heat conductor 14. The heat conductor 14 is connected to the heating element. One end of the heat conductor 14 is connected to the first inductive heating element 131, and the other end extends into the smoke-generating section 12. In addition to directly heating the smoke-generating section 12, part of the heat generated by the first inductive heating element 131 can also be transferred to the heat conductor 14 and introduced into the middle of the smoke-generating section 12 by the heat conductor 14, thereby increasing the heat-receiving area of the smoke-generating section 12 and enhancing the smoke-emitting speed.

[0041] In some embodiments, the heat conductor is a sheet formed by reconstituting high thermal conductivity material powder. For example, the heat conductor 14 is made of one or more of graphite powder, graphene, boron nitride, alumina, and carbon powder. In some embodiments, the thermal conductivity of the heat conductor 14 can be 1-500 W / m·K.

[0042] In some embodiments, the heat conductor is made of a non-magnetic induction material. In other embodiments, both the heat conductor and the heating element can be magnetic induction heating materials.

[0043] In some embodiments, the heat conductor 14 is a strip-shaped heat conductor made of a heat-conducting material, such as a heat-conducting member in the shape of a long strip or a long column, etc., to transfer the heat of the heating element to the smoke-generating section 12. When a sheet-shaped heat-conducting member is used, the contact area with the smoke-generating section 12 can be increased, and the heat transfer speed can be improved. When a column-shaped heat-conducting member is used, the strength of the heat-conducting member can be increased, ensuring the structural stability of the product. In some embodiments, the heat conductor 14 can be arranged along the length direction of the smoke-generating section 12 and is arranged at the axial position of the smoke-generating section 12, so that heating can be performed from the center, improving the heat transfer efficiency. The shape of the heat conductor 14 can be designed into various shapes according to needs, such as wavy, spiral, etc., further improving the uniformity of heat reception of the smoke-generating section 12.

[0044] In some embodiments, the air inlet hole 113 is provided through the side wall of the housing 11 that wraps the smoke-generating section 12. During suction, external air flow can directly enter the smoke-generating section 12 to quickly carry out the aerosol generated by the smoke-generating section 12. It can be understood that the opening position of the air inlet hole 113 can be adjusted according to actual needs. In some embodiments, the air inlet hole 113 is provided on the outer periphery of the lower part of the smoke-generating section 12, and the distance between the air inlet hole 113 and the end face of the smoke-generating section 12 close to the second end 112 is 1-20 mm. This allows more external air flow to pass through the smoke-generating section 12, which is more conducive to carrying out the generated aerosol.

[0045] In one embodiment, the intake holes 113 include one or more, and the opening size of a single intake hole 113 is 0.05 - 3 mm. The shape of the intake holes 113 can be one or more of a round hole, a square hole, an oval hole, a polygonal opening, and an opening with an irregular shape. The opening size is the maximum width of the contour of the opening. For example, for a round hole, it is the diameter; for an oval hole, it is the major diameter.

[0046] In some embodiments, there can be multiple intake holes 113, which are evenly distributed around the smoke-generating section 12, so as to make the intake more uniform.

[0047] In one embodiment, as Figure 2 shown, the heating element 13 can further include one or more layers of second induction heating elements 132 provided on the side of the first induction heating element 131 close to the first end 111. The second induction heating elements 132 are arranged at intervals with the first induction heating element 131, and the second induction heating elements 132 are horizontally arranged in the smoke-generating section 12.

[0048] When there is one layer of the second induction heating elements 132, the second induction heating elements 132 and the first induction heating element 131 are separated by a set distance in the axial direction of the smoke-generating section 12. The second induction heating elements 132 are arranged in the smoke-generating section 12 to better heat the smoke-generating material in the smoke-generating section 12.

[0049] As Figure 6 shown, when there are multiple second induction heating elements 132, the second induction heating elements 132 close to the second end 112 and the first induction heating element 131 are separated by a set distance in the axial direction of the smoke-generating section 12, and the multiple second induction heating elements 132 are arranged at intervals along the axial direction of the smoke-generating section 12 in the smoke-generating section 12. By providing one or more second induction heating elements 132, the first induction heating element 131 and each of the second induction heating elements 132 are distributed at intervals, and energy is provided to the matrix section in each layer respectively, and then the heat can be quickly and evenly transferred to the smoke-generating section 12.

[0050] In one embodiment, the first induction heating element 131 has an airtight structure. The first induction heating element 131 in a cylindrical aerosol-generating article can be a solid round disc, and its thickness can be 0.1 mm - 8 mm. The second induction heating elements 132 can also be in the form of round discs, and their thickness can be 0.1 mm - 8 mm.

[0051] In one embodiment, there may be a gap 114 between the second induction heating element 132 and the inner wall of the shell 11; or the second induction heating element 132 is provided with a through hole 1321 arranged along the axial direction of the shell 11 to form a channel for airflow to pass through. Of course, the gap 114 and the through hole 1321 may also be provided at the same time. The second induction heating element 132 may be a mesh structure, in which case the mesh hole is the through hole 1321. When the user inhales, the airflow entering from the air inlet 113 may flow through the gap 114 or the through hole 1321 to bring the aerosol of the smoking section 12 to the first end 111 for the user to inhale.

[0052] In some embodiments, the second induction heating element 132 can be integrally formed with the heat conductor 14 , thereby simplifying assembly and reducing production costs.

[0053] In some embodiments, the second induction heating element 132 and the heat conductor 14 are detachably connected to reduce production difficulty.

[0054] In some embodiments, the heat conductor 14 is provided with at least one spaced apart position along the length direction, and the second induction heating element 132 is snapped onto the space.

[0055] In some embodiments, the heat conductor 14 is provided with a plurality of positioning steps spaced apart along the length direction, and each second induction heating element 132 is provided with a positioning hole that cooperates with the positioning step. Through the cooperation of the positioning step and the positioning hole, the second induction heating element 132 is installed on the heat conductor 14 at intervals.

[0056] In some embodiments, when the aerosol generating product is used in conjunction with a heating device, the aerosol generating product is placed in an induction heating magnetic field for heating, and the heating temperature of the heating element is higher than the temperature of the heat conductor 14, that is, the first induction heating element 131 and the second induction heating element 132 are both higher than the heat conductor, and the temperature difference between the heating element (the first induction heating element 131 and the second induction heating element 132) and the heat conductor is in the range of 20-80°C. In this way, the smoke emission of the smoking section is faster in the part with higher temperature, and slower in the part with lower temperature, so how can the continuity of smoke emission be achieved?

[0057] In one embodiment, the smoking segment 12 is made of a smoking material, and the smoking material includes one or more of smoking particles, smoking sheets, smoking tobacco shreds, or a smoking block with a microporous structure.

[0058] In some embodiments, through holes 1321 are correspondingly formed in the second induction heating element 132 and / or there is a gap 114 between the second induction heating element 132 and the side wall of the housing 11. During assembly, the heating element can be integrally installed into the housing 11 so that the first induction heating element 131 seals to form a cavity in the housing 11. Smoke generating particles are selected and filled into the cavity from the first end to cover all the second induction heating elements 132. The smoke generating particles can fall through the gap 114 and / or the through holes 1321, and the smoke generating particles are compacted by means such as vibration, thereby forming the smoke generating section 12.

[0059] In some embodiments, during assembly, the first induction heating element 131 can also be first sealed at the second end 112 of the housing 11, then the smoke generating material is filled, then the second induction heating element 132 is installed, and then the smoke generating material is continuously filled on one side of the second induction heating element 132, and so on. The steps of filling the smoke generating material and installing the second induction heating element 132 are cycled multiple times as required.

[0060] In one embodiment, the aerosol generating article is provided with a spacer section 15 on the side of the first induction heating element 131 close to the second end 112. By providing the spacer section 15, after the aerosol generating article is heated and used, its heated end face will not be directly exposed, thus causing scalding to the user.

[0061] In some embodiments, the spacer section 15 includes a cavity portion 151, and the housing 11 forms a cavity portion 151 between the first induction heating element 131 and the second end 112, and / or the spacer section 15 includes a heat insulating member 152, the heat insulating member 152 is connected to the housing 11 and seals the second end 112 or seals on the side of the first induction heating element 131 close to the second end 112; or, the spacer section 15 includes a heat insulating layer 153 provided on the outer surface of the first induction heating element 131. The heat insulating member 152 and the heat insulating layer 153 can be made of heat insulating materials and the like.

[0062] In one embodiment, as Figure 1 shown, the spacer section 15 includes a cavity portion 151. The cavity portion 151 is formed between the first induction heating element 131 and the second end 112 of the housing 11 and is open to the second end 112. The provision of the cavity portion 151 enables the first induction heating element 131 to be located inside the housing 11, thus preventing the first induction heating element 131 from being directly exposed, thereby playing a role in preventing scalding of the user.

[0063] In one embodiment, as Figure 3As shown, the spacer section 15 includes a heat insulation member 152. The heat insulation member 152 is connected to the housing 11 and seals the second end 112 or is disposed on one side of the first induction heating element 131 close to the second end 112. By providing the heat insulation member 152, the risk of the user directly contacting the magnetic induction heating member can be further reduced, and the risk of being scalded can be further reduced.

[0064] It can be understood that a heat insulation member 152 can also be provided in the cavity portion 151, and a certain distance is left between the side of the heat insulation member 152 close to the second end 112 and the second end 112, so as to further play a role in preventing scalding.

[0065] In one embodiment, as Figure 4 shown, the spacer section 15 includes a heat insulation layer 153 provided on the outer surface of the first induction heating element 131. The heat insulation layer 153 can be a heat insulation film or other heat insulation material attached to the outer wall surface of the first induction heating element 131. Of course, the first induction heating element 131 can be exposed on the lower end surface of the housing 11 or located inside the housing 11.

[0066] In one embodiment, the ratio of the height of the cavity portion 151 in the axial direction to the diameter of the cavity portion 151 is greater than or equal to 0.3:1.

[0067] In one embodiment, as Figure 5 shown, the aerosol-generating article further includes a heat blocking member 19. The heat blocking member 19 is disposed at at least a part of the connection between the outer edge of the heating member 13 and the inner wall of the housing 11, separating the first induction heating member 13 from the inner wall of the housing 11, so as to avoid the housing 11 being heated to generate strange smells and affect the use experience.

[0068] In one embodiment, the aerosol-generating article further includes: a cooling section 17 and a filtering section 18 which are sequentially arranged from the second end 112 to the first end 111 inside the housing 11 and inside the smoking section 12. In some embodiments, the aerosol-producing article may further include a flavor-carrying section 16. In some embodiments, the housing 11 can be a paper tube wrapped around the periphery of the smoking section 12, the flavor-carrying section 16, the cooling section 17 and the filtering section 18. The paper tube is preferably a hard paper tube, or made of other materials, such as plastic, silicone, etc., and is made into a hollow cylinder.

[0069] In some embodiments, as Figure 7 shown, the present application further provides an aerosol generation system, including a heating device 20 and the aerosol-generating article 10 in any of the above embodiments; the heating device 20 includes an insertion space 21 for the aerosol-generating article 10 to be inserted and a magnetic field generator 22 provided outside the insertion space 21. The magnetic field generator 22 can be an induction heating coil matching the aerosol-generating article 10.

[0070] In one embodiment, the present application further provides a method for preparing an aerosol generating article. As Figure 8 shown, the preparation method includes the following steps:

[0071] Provide a housing 11;

[0072] An air inlet hole 113 is formed in the housing 11. It can be understood that the housing 11 can be a hard paper tube wound with hard paper, and the air inlet hole 113 can be formed before winding or after winding to form a hard paper tube.

[0073] The heating element 13 is disposed in the housing 11. Among them, the heating element 13 includes a first inductive heating element 131. The first inductive heating element 131 is horizontally disposed near the second end 112, and the edge of the first inductive heating element 131 is hermetically connected to the inner wall of the housing 11 to form an installation cavity;

[0074] Load the smoking material into the installation cavity from the first end 111.

[0075] It can be understood that the above steps can be adjusted in sequence as needed.

[0076] In some embodiments, when the smoking material of the smoking section 12 is in the form of smoking particles, the first inductive heating element 131 can first block one side of the housing 11 near the second end 112 to seal the bottom of the housing 11 to form an installation cavity, and then the smoking particles are filled to form the smoking section 12. Of course, in an embodiment provided with a second inductive heating element 132, a through hole 1321 is correspondingly formed in the second inductive heating element 132 and / or there is a gap 114 between the heating element 132 and the side wall of the housing 11, and the smoking particles can pass through the gap 114 and / or the through hole 1321 to facilitate the filling of the smoking particles.

[0077] In some embodiments, during assembly, the first inductive heating element 131 and the heat conductor can also be integrally installed in the housing. Among them, the first inductive heating element 131 first blocks the second end 112 of the housing 11, and then a layer of smoking material is filled. Then, the second inductive heating element 132 is installed on the side of the filled smoking material layer close to the first end 111. The second inductive heating element 132 can be supported by the smoking material or installed on the heat conductor, etc. Then, the smoking material is continuously filled on one side of the second inductive heating element 132, etc. In this way, the steps of installing the second inductive heating element 132 and filling the smoking material are cycled multiple times as needed.
