Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and particularly to aerosol generation products and aerosol generation systems. Background Technology

[0002] Tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion. An example of such a product is a heating device that releases the compounds by heating rather than burning the material. This material could be tobacco or other non-tobacco products, which may or may not contain nicotine.

[0003] Tobacco products can be made into an aerosol matrix layer and placed in a certain cavity, where they are heated by an aerosol generating device. However, traditional solutions require the design of a special receiving cavity to accommodate the aerosol matrix layer, which complicates the production process of aerosol-generated products and makes the aerosol matrix layer prone to falling off. Utility Model Content

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] The terms "first," "second," and "third" used in this application are for descriptive purposes only and should not be construed as indicating or implying the quantity or order of the indicated technical features relative to their importance. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship or movement of the components in a specific orientation (as shown in the accompanying drawings). If the specific orientation changes, the directional indication will also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0042] 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.

[0043] 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.

[0044] One embodiment of this application provides an aerosol-generating article, such as... Figure 1As shown, the device includes a housing 1, a positioning element 5, an aerosol matrix layer 2, a metal substrate 3, and a limiting element 6. An air passage 11 is defined within the housing 1. The positioning element 5 is fixed to the inner wall of the air passage 11 and has a through hole 51. The through hole 51 communicates with the periphery of the positioning element 5 to form a positioning notch 52, which communicates with the air passage 11. The metal substrate 3 and the aerosol matrix layer 2 are stacked and placed within the through hole 51. The positioning element 5 positions the metal substrate 3 and the aerosol matrix layer 2 in the circumferential direction of the metal substrate 3. The limiting element 6 is stacked and fixedly connected to the positioning element 5. The metal substrate 3 and the aerosol matrix layer 2 are sandwiched between the limiting element 6 and the inner wall of the housing 1. The limiting element 6 positions the metal substrate 3 and the aerosol matrix layer 2 in the axial direction of the metal substrate 3.

[0045] The aerosol generating article 10 provided in this application positions the metal substrate 3 and the aerosol matrix layer 2 in the circumferential direction using the positioning element 5, and positions the metal substrate 3 and the aerosol matrix layer 2 in the axial direction using the limiting element 6. This simplifies the manufacturing process of the aerosol generating article 10 and makes the metal substrate 3 and the aerosol matrix layer 2 more firmly fixed.

[0046] In one embodiment of this application, the aerosol matrix layer 2 and the metal substrate 3 can be stacked and in direct contact. In another embodiment of this application, the aerosol matrix layer 2 and the metal substrate 3 can be stacked and fixedly connected. It should be noted that the aerosol matrix layer 2 can be fixed to the surface of the metal substrate 3, and the aerosol matrix layer 2 and the metal substrate 3 are stacked. For example, in some examples, the aerosol generating matrix layer 2 can be bonded to the metal substrate 3.

[0047] It should be noted that the term "stacked" in this application can be interpreted broadly. It can be a limitation on the positional relationship between two components, but it does not specifically limit the contact relationship (e.g., direct contact or indirect contact) or connection relationship (e.g., no connection, fixed connection, or adhesive bonding).

[0048] In one embodiment of this application, the metal substrate 3 may be sheet-like. In another embodiment, the thickness of the metal substrate 3 is 0.05mm-0.15mm; specifically, the thickness may be 0.05mm, 0.10mm, 0.12mm, or 0.15mm. The metal substrate 3 has a certain rigidity, enabling it to support the aerosol-generating matrix layer 2. When fixed between the limiting member 6 and the inner wall of the shell 1, it is not easily deformed.

[0049] In one embodiment of this application, the metal substrate 3 comprises a sensitive metal or alloy that can be penetrated by a magnetic field and generate heat. When the metal substrate 3 is placed in a changing magnetic field, according to the law of electromagnetic induction, the magnetic flux passing through the metal substrate 3 changes, generating an induced electromotive force (EMF) within the metal substrate 3. Since the metal substrate 3 is a conductor with relatively low resistance, a closed loop is formed inside the metal substrate 3 under the influence of the induced EMF, generating induced eddy currents. As the eddy currents flow inside the metal substrate 3, electrical energy is converted into heat energy, thereby raising the temperature of the metal substrate 3. The heat generated by the metal substrate 3 can heat the aerosol-forming matrix layer 3.

[0050] In one embodiment of this application, the metal matrix 3 comprises a soft magnetic alloy. Soft magnetic alloys are widely used in energy conversion and signal processing fields due to their core advantages of high electromagnetic response, low loss, and high saturation magnetization.

[0051] In one embodiment of this application, the metal substrate 3 includes aluminum foil, nickel-iron alloy, high-nickel alloy, stainless steel, or pure iron.

[0052] In one embodiment of this application, a positioning burr is provided at the edge of the metal substrate 3, and the positioning burr passes through the housing 1. In this way, the positioning burr can be used for positioning.

[0053] In one embodiment of this application, the metal substrate 3 is mesh-like, allowing aerosols generated by heating the aerosol matrix layer 2 to pass through the mesh openings of the metal substrate 3. In another embodiment, the metal substrate 3 may include through-holes penetrating both surfaces of the metal substrate 3, allowing air or aerosols to pass freely. Thus, when the metal substrate 3 heats the aerosol matrix layer 2, aerosols are generated, and these aerosols can flow from one side of the metal substrate 3 to the other side through the through-holes. In one embodiment, the through-holes are formed by mechanical processing or chemical etching. In another embodiment, mechanical processing includes drilling or laser processing.

[0054] In one embodiment of this application, the metal substrate 3 is formed by punching, rolling, and deposition.

[0055] In one embodiment of this application, the aerosol matrix layer 2 includes tobacco extract. The tobacco extract can be obtained by extracting extracts from tobacco leaves and flowers using a solvent, then extracting the extracts with ethanol, followed by drying, dehydration, desalting, and cooking of the raw materials, adding an extract with a special aroma, and performing ultrasonic-assisted extraction to finally obtain a tobacco extract with a specific flavor. In one embodiment of this application, the tobacco extract is mainly used for tobacco flavoring, which can enhance the aroma, reduce off-flavors, and improve cigarette quality. Its aroma is realistic and natural, making it an excellent raw material for cigarette flavoring. Furthermore, tobacco extract can also be used in daily-use fragrances to provide unique aromas and flavors.

[0056] In one embodiment of this application, the main components of the tobacco extract include furfuryl alcohol, benzyl alcohol, phytol, solanone, β-turfayne, β-ionone, hexahydrofarnesone, diene, daidzeinone, dihydroactinolone, isopentenone, indole, etc.

[0057] In one embodiment of this application, the positioning member 5 is fixedly connected to the housing 1 so that the positioning part 51 of the positioning member 5 can position the metal substrate 3 and the aerosol matrix layer 2.

[0058] In one embodiment of this application, such as Figure 3 As shown, the positioning element 5 is attached to the inner wall of the housing 1, and the through hole 51 communicates with the periphery of the positioning element 5 to form a positioning notch 52. At least a portion of the edge of the aerosol matrix layer 2 is fitted into the positioning notch 52. The positioning notch 52 has a limiting effect on the aerosol matrix layer 2 and the metal substrate 3, and the inner edge of the positioning notch 52 can limit the movement of the aerosol matrix layer 2 and the metal substrate 3 in the circumferential direction.

[0059] In one embodiment of this application, the positioning member 5 is flat, and the contact area between the inner wall of the air passage 11 and the positioning member 5 is planar. The positioning member 5 is bonded to the inner wall of the air passage 11. This improves the stability of the fit between the positioning member 5 and the inner wall of the air passage 11.

[0060] In one embodiment of this application, the limiting member 6 is provided with a vent 61, and the metal substrate 3 is partially exposed to the vent 61, so that the aerosol generated by heating the metal substrate 3 can pass through the vent 61 and enter the air passage 11 of the housing 1.

[0061] In one embodiment of this application, the housing 1 is provided with a first mounting hole 15, the positioning member 5 is provided with a second mounting hole 53, and the limiting member 6 is provided with a third mounting hole 62. During the installation of the aerosol generating product 10, the first mounting hole 15, the second mounting hole 53 and the third mounting hole 62 pass through the mounting post for positioning and installation.

[0062] In one embodiment of this application, both the limiting member 6 and the positioning member 5 are sheet-like and are bonded together. In another embodiment, the limiting member 6 and the positioning member 5 are stacked, with the positioning member 5 located between the limiting member 6 and the housing 1. Further, one side of the positioning member 5 is bonded to the housing 1, and the other side is bonded to the limiting member 6. The metal substrate 3 and the aerosol matrix layer 2 are embedded in the positioning notch 52, and both are sandwiched between the limiting member 6 and the housing 1. The limiting member 6 positions the metal substrate 3 and the aerosol matrix layer 2 along the axis of the metal substrate 3, and the positioning member 5 positions the metal substrate 3 and the aerosol matrix layer 2 in the circumferential direction of the metal substrate 3. Furthermore, the positioning notch 52 can serve as a channel for aerosol to escape into the airway 11.

[0063] In one embodiment of this application, at least one of the limiting member 6, the positioning member 5, and the housing 1 is made of paper.

[0064] In one embodiment of this application, such as Figure 2 As shown, the housing 1 includes a first part 13 and a second part 14. A metal substrate 3 and an aerosol matrix layer 2 are stacked on the first part 13, and a positioning member 5 is bonded to the first part 13. The second part 14 is connected to the first part 13, and the second part 14 is folded relative to the first part 13 to form an air passage 11.

[0065] In one embodiment of this application, two second parts 14 are connected to the two sides of the first part 13 respectively. The two second parts 14 are bent toward the first part 13 and stacked and bonded. After the two second parts 14 are stacked, they are opposite to the first part 13. In the manufacturing process of the aerosol generating article 10, a flat material can be folded and bonded to form the shell 1, making the manufacturing process of the shell 1 simple and convenient.

[0066] In one embodiment of this application, the second part 14 includes a bent section 141 and an overlapping section 142 connected to the bent section 141. The bent section 141 is connected to the first part 13. The two overlapping sections 142 are stacked. The bent section 18 is opposite to the positioning notch 52, and the bent section 18 seals the metal substrate 3 and the aerosol matrix layer 2 inside the positioning notch 52. The two overlapping sections 142 are stacked and opposite to the first part 13, so that after the aerosol generating article 10 is installed into the heating chamber of the aerosol generating device, the first part 13 is located at the bottom of the heating chamber, and the two overlapping sections 142 are located on the opening side of the heating chamber. The thickness of the two overlapping sections 142 after stacking does not affect the assembly of the housing 1 and the heating chamber.

[0067] In one embodiment of this application, the through hole 51 is a circular hole, and the arc corresponding to the positioning notch 52 is greater than or equal to 45°. In one embodiment of this application, as... Figure 3As shown, the arc corresponding to the positioning notch 52 can be 90°. In other embodiments of this application, the arc corresponding to the positioning notch 52 can be 45°.

[0068] Accordingly, both the metal substrate 3 and the aerosol matrix layer 2 are circular sheet structures, and the metal substrate 3 and the aerosol matrix layer 2 can be adapted to the circular through hole 51.

[0069] In one embodiment of this application, such as Figure 4 As shown, a positioning rib 3b is provided at the edge of the metal substrate 3. The positioning rib 3b has a bent structure and passes through the shell 1. The positioning rib 3b positions the metal substrate 3 in the circumferential direction and fixes the metal substrate 3 to the shell 1.

[0070] In one embodiment of this application, the aerosol matrix layer 2 is bonded to the housing 1. In another embodiment of this application, the aerosol matrix layer 2 is bonded to the housing 1 using an adhesive material that does not produce odor when heated, so that the adhesive material does not affect the taste of the aerosol when the aerosol matrix layer 2 is heated.

[0071] In one embodiment of this application, the aerosol matrix layer 2 is coated on the metal substrate 3, so that the contact effect between the aerosol matrix layer 2 and the metal substrate 3 is good, and the aerosol matrix layer 2 is not easy to fall off the metal substrate 3.

[0072] Another embodiment of this application provides an aerosol generation system 100, such as Figure 5 As shown, it includes an aerosol generating device 20 and the aforementioned aerosol generating product 10. The aerosol generating device 20 heats the aerosol generating product 10 to generate aerosol.

[0073] In one embodiment of this application, the aerosol generating device 20 may include a coil. When the coil is energized, it can convert an electric field into a magnetic field. Under the action of the magnetic field, the metal substrate 3 generates an induced current and heats up, thereby heating the aerosol matrix layer 2 to generate aerosol.

[0074] 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.
