[0048] One embodiment of this application provides a tobacco segment 10, including a composite tobacco sheet 1 and a filling matrix 2. The composite tobacco sheet 1 includes a metal substrate 11, a first matrix layer 12, and a second matrix layer 13. The metal substrate 11 is flexible. The first matrix layer 12 is disposed on one side surface of the metal substrate 11. The second matrix layer 13 is disposed on the other side surface of the metal substrate 11. The composite tobacco sheet 1 is wound into a hollow cylindrical shape, forming a receiving cavity 14, which is filled with the filling matrix 2.

[0049] The tobacco segment 10 of this application includes a composite tobacco sheet 1 and a filling matrix 2. The metal substrate 11 of the composite tobacco sheet 1 is provided with a first matrix layer 12 and a second matrix layer 13 on both sides, so that the aerosol generating product can obtain a sufficient amount of smoke when inhaled, so that the user's taste remains consistent before and after inhalation.

[0050] In one embodiment of this application, the filling matrix 2, the first matrix layer 12, and the second matrix layer 13 are all materials capable of generating aerosols.

[0051] In one embodiment of this application, the material generating the aerosol may include 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.

[0052] 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.

[0053] In some embodiments, the first matrix layer 12 and the second matrix layer 13 can be sheet structures formed by a predetermined process from a slurry containing materials that generate aerosols. The first matrix layer 12 and the second matrix layer 13 can generate aerosol gas under high-temperature baking.

[0054] In one embodiment of this application, the filling matrix 2 comprises ordered or disordered tobacco. In another embodiment of this application, the filling matrix 2 comprises shredded tobacco, tobacco sheets, or tobacco particles. In yet another embodiment of this application, the interior of the filling matrix 2 is porous, allowing air to pass through, or allowing the aerosol generated after the filling matrix 2 is heated.

[0055] In one embodiment of this application, the metal substrate 11 is sheet-shaped, and a first matrix layer 12 and a second matrix layer 13 are provided on two sides of the metal substrate 11, so that the first matrix layer 12 and the second matrix layer 13 on both sides of the metal substrate 11 can quickly produce aerosol after the metal substrate 11 is heated.

[0056] In one embodiment of this application, at least one of the first substrate layer 12 and the second substrate layer 13 is a substrate layer formed by a casting process. In another embodiment of this application, at least one of the first substrate layer 12 and the second substrate layer 13 is a substrate layer formed by a spraying process.

[0057] In one embodiment of this application, the metal substrate 11 is flexible, which makes the composite tobacco sheet 1 flexible, so that the composite tobacco sheet 1 can be rolled up to form a cylindrical shape.

[0058] In one embodiment of this application, the thickness of the metal substrate 11 is 3 μm-30 μm. In another embodiment, the thickness of the metal substrate 11 is 6 μm-30 μm. In yet another embodiment, the thickness of the metal substrate 11 is 10 μm-30 μm. In still another embodiment, the thickness of the metal substrate 11 is 3 μm, 6 μm, 10 μm, 12 μm, 15 μm, 20 μm, 18 μm, 20 μm, 25 μm, or 30 μm. The thickness of the metal substrate 11 allows it to maintain a certain structural strength to support the aerosol-forming matrix layer 12 coated thereon, while also maintaining a certain degree of flexibility so that it can be bent.

[0059] In one embodiment of this application, the metal substrate 11 comprises a sensitive metal or alloy that can be penetrated by a magnetic field and generate heat. When the metal substrate 11 is in a changing magnetic field, according to the law of electromagnetic induction, the magnetic flux passing through the metal substrate 11 changes, generating an induced electromotive force (EMF) inside the metal substrate 11. Since the metal substrate 11 is a conductor with relatively low resistance, a closed loop is formed inside the metal substrate 11 under the action of the induced EMF, generating induced eddy currents. When the eddy currents flow inside the metal substrate 11, electrical energy is converted into heat energy, thereby raising the temperature of the metal substrate 11. The heat generated by the metal substrate 11 can heat the first matrix layer 12 and the second matrix layer 13.

[0060] In one embodiment of this application, the metal substrate 11 includes aluminum foil, nickel-iron alloy, high-nickel alloy, stainless steel, or pure iron.

[0061] In one embodiment of this application, the metal substrate 11 comprises one or more layers.

[0062] In one embodiment of this application, the metal substrate 11 is provided with through holes 111 penetrating both sides of the metal substrate 11, allowing air or aerosol to pass through freely. Thus, when the metal substrate 11 heats the first matrix layer 12 and the second matrix layer 13, it generates aerosol, which can flow from one side of the metal substrate 11 to the other side through the through holes 111.

[0063] In one embodiment of this application, the through holes 111 are arranged in an ordered or random manner. In one embodiment of the application, the through holes 111 may be arranged in an array. In one embodiment of this application, the through holes 111 may be arranged in a circular, elliptical, racetrack-shaped, rectangular, triangular-hexagonal, or other shape. In one embodiment of this application, the through holes 111 may be arranged in a centrally symmetric or axially symmetric pattern.

[0064] In one embodiment of this application, the cross-section of the through hole 111 is circular, polygonal, or irregular in shape. In another embodiment of this application, the cross-section of the through hole 111 is triangular, rectangular, circular, elliptical, racetrack-shaped, hexagonal, or other irregular in shape.

[0065] In one embodiment of this application, there are multiple through holes 111, and the opening ratio of the multiple through holes 111 on the metal substrate 11 is 20%-50%. In one embodiment of this application, the opening ratio of the multiple through holes 111 on the metal substrate 11 is 20%, 25%, 30%, 35%, 40%, 45%, or 50%. In this way, aerosols can pass smoothly through the through holes 111 and flow smoothly on both sides of the metal substrate 11.

[0066] In one embodiment of this application, the through hole 111 is formed by machining or chemical etching. In one embodiment of this application, machining includes drilling or laser processing.

[0067] In one embodiment of this application, the thermal conductivity of the metal substrate 11 is at least 25 W / m·K. In another embodiment of this application, the thermal conductivity of the metal substrate 11 is 25 W / m·K, 30 W / m·K, 32 W / m·K, 35 W / m·K, 40 W / m·K, or 45 W / m·K.

[0068] In one embodiment of this application, the metal substrate 11 is formed by rolling and deposition.

[0069] In one embodiment of this application, the tobacco segment 10 further includes a wrapping element 3, which is wrapped around the outer periphery of the composite tobacco sheet 1 rolled into a cylindrical shape. In some examples, the wrapping element 3 is an integrally formed tube or a wound tube.

[0070] In one embodiment of this application, when the package 3 is an integrally formed tube, the wound composite tobacco sheet 1 is sleeved inside the package 3. In another embodiment of this application, when the package 3 is a wound tube, the package 3 can be wound together with the composite tobacco sheet 1.

[0071] In one embodiment of this application, when the package 3 is a wound tube, the package 3 is formed by winding a sheet of forming paper around it. At this time, the composite tobacco sheet 1 and other structures are wrapped inside by the forming paper.

[0072] In one embodiment of this application, when the package 3 is a wound tube, the package 3 is formed by a long strip of forming paper wound in a spiral shape. At this time, the composite tobacco sheet 1 and other structures are wrapped inside the forming paper by the forming paper through a multi-turn winding structure.

[0073] In one embodiment of this application, a first matrix layer 12 or a second matrix layer 13 is disposed between the package 3 and the composite tobacco sheet 1, thereby increasing the amount of smoke generated by the aerosol-generating article 100 during inhalation. In this way, the first matrix layer 12 or the second matrix layer 13 can separate the metal matrix layer 11 of the composite tobacco sheet 1 from the package 3, preventing the metal matrix layer 11 from directly baking the package 3, and also increasing the tobacco product content within the aerosol-generating article 100.

[0074] In one embodiment of this application, the two ends of the composite tobacco sheet 1 in the winding direction are the starting end 15 and the ending end 16. On the composite tobacco sheet 1 wound into a cylindrical shape, there is a gap 17 between the starting end 15 and the ending end 16, so that the two ends of the metal substrate 11 do not overlap, making the temperature field distribution of the metal substrate 11 more uniform. This avoids the occurrence of a low temperature zone at the overlap of the two ends of the metal substrate 11, thereby avoiding insufficient heating of the first matrix layer 12 and the second matrix layer 13 corresponding to the overlap of the two ends of the metal substrate 11.

[0075] One embodiment of this application provides an aerosol-generating article 100, comprising at least one tobacco segment 10 as described above.

[0076] In one embodiment of this application, the aerosol generating article 100 includes cigarette paper 20 and filter segment 30, hollow segment 40, tobacco segment 10 and plug 50 arranged sequentially in the axial direction of the aerosol generating article. The cigarette paper 20 wraps the filter segment 30, hollow segment 40, tobacco segment 10 and plug 50 into a cylindrical shape.

[0077] In one embodiment of this application, the filter segment 30 is available for a user to hold in their mouth. In one embodiment of this application, the hollow segment 40 can cool the aerosol generated by the tobacco segment 10. In one embodiment of this application, the plug 50 prevents the filling matrix 2 from leaking while allowing air to pass through.

[0078] In one embodiment of this application, the hollow section 40 is multi-segmented, and the multi-segment hollow section 40 is arranged sequentially along the axial direction of the aerosol generating article 100. The multi-segment hollow section 40 allows the aerosol to be cooled to a suitable temperature, thereby providing the user with a good taste.

[0079] One embodiment of this application provides an aerosol generation system 1000, including an aerosol generation device 200 and the aforementioned aerosol generation article 100. The aerosol generation device 200 heats the composite smoke sheet 1 to generate aerosol.

[0080] 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.
