DETAILED DESCRIPTION

[0028] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. 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, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and 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 implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

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

[0031] In view of the problem that the existing aerosol generating products have a small heating area, in the present application, the protrusion of the receptor is designed to increase the surface area of ​​the receptor, thereby increasing the heating area of ​​the receptor, that is, increasing the heating area of ​​the aerosol generating substrate, which can more fully stimulate the generation of aerosols of the aerosol generating substrate.

[0032] Please refer to Figures 1 to 7 In one embodiment, an aerosol generating product 10 is provided, which mainly includes a wrapping member 11, a matrix portion 12 and a receptor 13, etc.

[0033] The wrapping member 11 can wrap the matrix portion 12 and the receptor 13 therein to form a whole, which is then inserted into the atomizing device 20 and heated to generate aerosol for the user to inhale.

[0034] The matrix portion 12 includes a first aerosol generating substrate 121 for generating aerosol when heated for inhalation by a user.

[0035] The susceptor 13 is used to heat the substrate 12, and includes a connecting portion 131 and a protruding portion 132. The connecting portion 131 may be formed at least partially at the edge of the susceptor 13 and fixed to the inner wall 111 of the package 11. The protruding portion 132 is arched toward the substrate 12 to heat the first aerosol generating substrate 121.

[0036] Since the receptor 13 includes a connection portion 131 formed at at least part of the edge and a protrusion 132 arched toward the matrix portion 12, the receptor 13 can be fixed to the inner wall 111 of the package 11 only by the connection portion 131, which can effectively reduce the contact area between the receptor 13 and the package 11, thereby reducing the heat transfer from the receptor 13 to the package 11, which has the advantage of effectively reducing the surface temperature of the aerosol generating product.

[0037] At the same time, due to the provision of the protrusion 132, the surface area of ​​the receptor 13 is increased, thereby increasing the heating area of ​​the receptor 13, that is, increasing the heating area of ​​the first aerosol generating substrate 121, and more fully stimulating the generation of aerosol of the aerosol generating substrate.

[0038] It is understood that in some embodiments, the aerosol generating article 10 may further include a cooling portion 14, a filtering portion 15, etc. The substrate portion 12, the cooling portion 14, and the filtering portion 15 are arranged in the direction of the airflow and are wrapped as a whole by the wrapping member 11; of course, the wrapping member 11 may be one or more. During inhalation, the aerosol generated by the substrate portion 12 is cooled by the cooling portion 14, filtered by the filtering portion 15, and then inhaled by the user.

[0039] In one embodiment, if Figure 2 As shown, the aerosol generating article further includes a heat insulating layer 18. The heat insulating layer 18 is disposed at the connection position between the connecting portion 131 and the inner wall 111 of the package 11, and is configured to isolate the connecting portion 131 from the inner wall 111 of the package 11. By providing the heat insulating layer 18, the heat generated by the receptor 13 can be further reduced from being transferred to the package 11, thereby preventing the package 11 from generating stray air, and also reducing the temperature of the outer wall of the package 11, thereby improving the user experience. In some embodiments, the heat insulating layer 18 can be made of a composite heat insulating material, and of course, it can also be made of other materials with higher thermal resistance.

[0040] In one embodiment, a cavity 16 is formed between the receptor 13 and the inner wall 111 of the wrapper 11. The formation of the cavity 16 prevents the heat of the receptor 13 from being directly transferred to the wrapper 11, thereby preventing the wrapper 11 from generating unwanted gas due to baking, further ensuring that the aerosol is generated more purely and improving the user's smoking taste experience.

[0041] In some embodiments, the cavity 16 is not filled with any substance, and the air entering the aerosol generating product 10 during inhalation can be used to cool the air, which can further reduce the temperature of the outer wall of the aerosol generating product 10 to avoid the user's skin from feeling hot when it touches the skin.

[0042] In one embodiment, if Figure 3As shown, the cavity 16 can also be filled with a second aerosol generating substrate 123. The second aerosol generating substrate 123 can be made of the same or different aerosol generating substrate as the first aerosol generating substrate 121 of the substrate portion 12; in some embodiments, the aerosol generating substrate can be a tobacco material or a non-tobacco material, for example, tobacco particles, tobacco shreds, tobacco sheets, etc., or a carrier for adsorbing smoke-generating agents, and the smoke-generating agent can be glycerin, propylene glycol, nicotine extract, etc. In some embodiments, the first aerosol generating substrate 121 and the second aerosol generating substrate 123 can both be made of at least one aerosol generating substrate. When inhaling, the receptor 13 can simultaneously heat the second aerosol generating substrate 123 in the cavity 16 and the first aerosol generating substrate 121 of the substrate portion 12, thereby increasing the amount of aerosol generated. The aerosol generating substrate can also be configured to contain flavor materials, such as spices, flavoring agents, etc. It can be understood that when different aerosol generating substrates are used, different flavors can also be added to enhance the user experience.

[0043] In one embodiment, if Figure 4 As shown, the cavity 16 may also be filled with a heat insulating material 122 , thereby better isolating the heat of the susceptor 13 from being transferred to the packaging member 11 .

[0044] In one embodiment, the aerosol generating product further includes an adhesive layer 17. The connecting portion 131 is fixedly connected to the inner wall 111 of the wrapping member 11 through the adhesive layer 17, so that the entire susceptor 13 can be stably positioned in the wrapping member 11, thereby maintaining the consistency of the entire aerosol generating product 10, making the heating of the matrix portion 12 more stable, and thus generating a stable aerosol output. Among them, the heat insulation layer 18 is arranged between the connecting portion 131 and the adhesive layer 17, so as to prevent the susceptor 13 from heating the adhesive layer 17, thereby preventing the volatile substances of the adhesive layer 17 from being vaporized and generating impurities.

[0045] In one embodiment, if Figure 5 As shown, the connection portion 131 is formed at the entire periphery of the susceptor 13; the heat insulation layer 18 is disposed between the connection portion 131 and the inner wall 111 of the wrapping member 11. The connection portion 131 may be partially or completely connected to the inner wall 111 of the wrapping member 11 through the adhesive layer 17.

[0046] In one embodiment, if Figure 6 , Figure 7 As shown, the connection portion 131 is formed at a portion of the periphery of the susceptor 13; the heat insulation layer 18 is disposed between the connection portion 131 and the inner wall 111 of the wrapping member 11. The connection portion 131 may be partially connected to the inner wall 111 of the wrapping member 11 through the adhesive layer 17.

[0047] Furthermore, in some embodiments, the heat insulating layer 18 may be disposed between the edge of the receptor 13 where the connection portion 131 is not provided and the inner wall 111 of the wrapping member 11 , thereby preventing the heat generated by the receptor 13 from being transferred to the wrapping member 11 .

[0048] The protrusion 132 may be one or more. In one embodiment, Figure 8 As shown, there may be a plurality of protrusions 132. By providing a plurality of protrusions 132, the heating area can be further increased, and the heating efficiency can be further improved.

[0049] In one embodiment, the susceptor 13 may be provided with a plurality of ventilation channels 133 extending through the thickness direction thereof. The ventilation channels 133 may include a plurality of through holes 1331 arranged in a row (e.g. Fig. 9 ) or a grid-like through hole 1332 (as shown Fig.10 As shown), airflow can enter from the wrapping member 11 and then enter the matrix portion 12 through the through holes, thereby reducing airflow resistance.

[0050] In one embodiment, the susceptor 13 may be a sheet-shaped induction heating element made of an inductively heatable metal. The susceptor 13 may be made of various existing electromagnetic induction materials, which are not limited herein.

[0051] In one embodiment, the sensor 13 is configured as a combination of a connection portion 131 and a protrusion 132; the connection portion 131 is made of a non-inductive material; and the protrusion 132 is made of an inductive heating material. By using the connection portion 131 made of a non-inductive material to connect with the wrapping member 11, the connection portion 131 will not induce heat during operation, thereby avoiding the connection portion 131 heating the wrapping member 11 and preventing the wrapping member 11 from overheating and generating impurities.

[0052] In one embodiment, the receptor 13 is a hollow integral component, in which the matrix portion 12 is disposed. The integral component is a columnar or conical cylinder, and of course, the integral component can also be other three-dimensional shapes. This integrated design can facilitate the filling of the first aerosol generating substrate 121. For example, a granular first aerosol generating substrate 121 can be directly filled into the receptor 13.

[0053] In one embodiment, there may be a plurality of susceptors 13, which are evenly distributed around the periphery of the matrix portion 12. The multi-piece design facilitates assembly. The susceptor 13 may be in the form of a sheet, and its shape may be a quadrilateral, triangle, pentagon, circle or irregular shape.

[0054] In one embodiment, the wrapping member 11 can be made of paper material, and the matrix portion 12 and the susceptor 13 are wrapped therein by rolling. Of course, the wrapping member 11 can also be made of other materials, such as non-woven fabrics, fabrics, or other flame-resistant materials, which are not limited here.

[0055] In one embodiment, the first aerosol generating substrate 121 of the matrix portion 12 may include a smoke generating agent, a tobacco material, etc. In some embodiments, various materials such as flavoring agents, wetting agents, and fragrances may also be included. The provision of the protrusion 132 increases the heating area, and the various materials mentioned above may be better stimulated to obtain corresponding aerosol substances, which may further enhance the user's smoking experience.

[0056] In one embodiment, if Figure 6 As shown, the connection portion 131 is arranged in a direction substantially parallel to the airflow direction of the aerosol generating article 10. By means of this parallel arrangement, an airflow channel can be formed between the inner wall 111 of the wrapping member 11 and the receptor 13 during inhalation, so that heat can be removed by the airflow, thereby preventing the wrapping member 11 from overheating and generating stray gas.

[0057] In one embodiment, the connection portion 131 is disposed in a direction that intersects with the airflow direction of the aerosol generating article 10. Figure 7 As shown, the two are arranged orthogonally; it is understandable that the two can also be arranged staggered at a certain angle. Through the staggered arrangement, during inhalation, the airflow enters the position of the receptor 13 from the wrapping member 11, is heated by the receptor 13, and then enters the matrix portion 12, so that the matrix portion 12 can receive more heat, thereby being better heated, and then better generating aerosol for inhalation.

[0058] Please refer to Fig.11 In one embodiment, an atomization system is provided, which mainly includes an atomization device 20 and an aerosol generating product 10 of any of the above embodiments.

[0059] The atomizing device 20 mainly includes a housing 21 and a sensing element 22 . The housing 21 is formed with a receiving space 211 for receiving the aerosol generating product 10 .

[0060] The induction element 22 is disposed in the housing 21 and is used to heat the susceptor 13 of the aerosol generating article 10, so as to heat the first aerosol generating substrate 121 of the aerosol generating article 10 and generate aerosol. The induction element 22 may be an electromagnetic induction element 22, which heats the susceptor 13 by the electromagnetic induction principle.

[0061] In one embodiment, the atomization device 20 may further include a power supply component 23. The power supply component 23 is electrically connected to the sensing element 22 to supply power.

[0062] When the user needs to inhale, the aerosol generating product 10 is inserted into the accommodating space 211, and the power supply component 23 is triggered to supply power to the sensing element 22 by inhalation or pressing a button. At this time, the receptor 13 in the aerosol generating product 10 is heated, and the heat of the receptor 13 is transferred to the first aerosol generating substrate 121 of the matrix portion 12 through the protrusion 132. The first aerosol generating substrate 121 is heated to generate aerosol for the user to inhale.

[0063] Due to the provision of the protrusion 132, the surface area of ​​the receptor 13 is increased, thereby increasing the heating area of ​​the receptor 13 and the heating area of ​​the first aerosol generating substrate 121, thereby more fully stimulating the generation of aerosol of the aerosol generating substrate.

[0064] In addition, the cavity 16 formed between the receptor 13 and the inner wall 111 of the wrapping 11 prevents the heat of the receptor 13 from being directly transferred to the wrapping 11, thereby preventing the wrapping 11 from generating unwanted gas due to baking, which can further ensure that the aerosol generation is purer and improve the user experience.

[0065] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
