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.

[0041] One embodiment of this application provides an aerosol generating article 10, including a shell 1, an aerosol matrix layer 2, and a metal substrate 3. An air passage 11 is defined within the shell 1, and a portion of the shell 1 protrudes into the air passage 11 to form a positioning post 17. The metal substrate 3 and the aerosol matrix layer 2 are stacked, and the positioning post 17 passes through the metal substrate 3 or the aerosol matrix layer 2 to confine the metal substrate 3 and the aerosol matrix layer 2 within the air passage 11. When the aerosol matrix layer 2 is heated to generate aerosol, the aerosol enters the air passage 11.

[0042] The aerosol generating article 10 provided in this application fixes the metal substrate 3 and the aerosol matrix layer 2 to the shell 1 through the positioning column 17, which simplifies the production process of the aerosol generating article 10 and makes the aerosol matrix layer 2 more firmly fixed.

[0043] 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, 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 stacking position of the aerosol matrix layer 2 and the metal substrate 3 is specified. For example, in some examples, the aerosol generating matrix layer 2 can be bonded to the metal substrate 3.

[0044] 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).

[0045] In one embodiment of this application, the metal substrate 3 is located between the shell 1 and the aerosol matrix layer 2, and the positioning post 17 fixes both the aerosol matrix layer 2 and the metal substrate 3 to the shell 1. In another embodiment of this application, the aerosol matrix layer 2 is located between the shell 1 and the metal substrate 3, thereby clamping the aerosol matrix layer 2 between the shell 1 and the metal substrate 3, making it less likely for the aerosol matrix layer 2 to detach.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In one embodiment of this application, the metal substrate 3 includes aluminum foil, nickel-iron alloy, high-nickel alloy, stainless steel, or pure iron.

[0050] 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.

[0051] 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.

[0052] In one embodiment of this application, the metal substrate 3 is formed by punching, rolling, and deposition.

[0053] 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.

[0054] 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.

[0055] In one embodiment of this application, both the metal substrate 3 and the aerosol matrix layer 2 are provided with positioning holes 2a, and the positioning post 17 is inserted into the positioning hole 2a.

[0056] In one embodiment of this application, the free end of the positioning post 17 has a flange that folds outward toward the radial side of the positioning post 17, so that the metal substrate 3 and the aerosol matrix layer 2 are sandwiched between the inner wall of the housing 1 and the flange, thereby positioning the metal substrate 3 and the aerosol matrix layer 2 on the axis.

[0057] In one embodiment of this application, the aerosol generating article 10 further includes a positioning member 5, which is partially stacked and fixedly connected to the shell 1. The positioning member 5 is used to position the metal substrate 3 and the aerosol matrix layer 2. In one embodiment of this application, the positioning member 5 includes a positioning part 51, and the aerosol matrix layer 2 is disposed on the positioning part 51.

[0058] 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. The positioning part 51 can position the metal substrate 3 and the aerosol matrix layer 2 in the circumferential direction.

[0059] In one embodiment of this application, the positioning member 5 is attached to the inner wall of the housing 1, and the positioning part 51 is a positioning notch 52, with at least a portion of the edge of the aerosol matrix layer 2 fitting 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.

[0060] 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.

[0061] In one embodiment of this application, both the aerosol matrix layer 2 and the metal substrate 3 are circular, and the positioning notches 52 are arc-shaped. In another embodiment of this application, the aerosol matrix layer 2 and the metal substrate 3 form a composite smoke sheet, which is arranged in a 2*3 array, and the positioning element 5 has six positioning notches 52. In one embodiment of this application, the positioning notch 52 at the center of the positioning element 5 is a half-circle arc, and the positioning notches 52 at both ends of the positioning element 5 are quarter-circles arcs. In one embodiment of this application, all six positioning notches 52 are half-circles arcs.

[0062] In one embodiment of this application, the aerosol-generating article 10 further includes a limiting member 6, which is fixedly connected to a positioning post 17. The metal substrate 3 and the aerosol matrix layer 2 are sandwiched between the limiting member 6 and the inner wall of the shell 1, such that the limiting member 6 limits the displacement of the metal substrate 3 and the aerosol matrix layer 2 in a direction perpendicular to the metal substrate 3. That is, the limiting member 6 can position the metal substrate 3 and the aerosol matrix layer 2 in the axial direction of the metal substrate 3. In one embodiment of this application, the limiting member 6 is bonded to the positioning post 17.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] In one embodiment of this application, 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. For example, the positioning rib 3b can be bent and passed through the shell 1.

[0067] In one embodiment of this application, a plurality of positioning ribs 3b may be provided on each metal substrate 3, and the plurality of positioning ribs 3b are spaced apart along the circumferential direction of the metal substrate 3.

[0068] 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.

[0069] In one embodiment of this application, the aerosol matrix layer is coated on the metal substrate, so that the contact effect between the aerosol matrix layer 2 and the metal substrate 3 is good, and the matrix layer 2 is not easy to fall off the metal substrate 3.

[0070] In one embodiment of this application, the housing 1 includes a first portion 13 and a second portion 14. A metal substrate 3 and an aerosol matrix layer 3 are stacked on the first portion 13. The second portion 14 is connected to the first portion 13 and is folded relative to the first portion 13 to form an air passage 11, within which the metal substrate 3 and the aerosol matrix layer 2 are located.

[0071] Another embodiment of this application provides an aerosol generation system 100, including an aerosol generation device 20 and the aforementioned aerosol generation article 10, wherein the aerosol generation device 20 heats the aerosol generation article 10 to generate aerosol.

[0072] 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.

[0073] 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.
