[0074] The following reference Figures 1-25This application provides a detailed description of composite tobacco sheets, tobacco segments, aerosol generating articles, and aerosol generating systems according to embodiments of the present application. It is important to understand that the following description is merely illustrative and not intended to limit the scope of the application.

[0075] One embodiment of this application provides a composite tobacco sheet 1, such as... Figure 1 As shown, it includes a metal substrate 11 and an aerosol generation matrix layer 12. The aerosol generation matrix layer 12 is coated on the surface of the metal substrate 11 to form a composite smoke sheet 1, which can be heated to generate aerosols.

[0076] It should be noted that when the aerosol generating matrix is ​​coated onto the metal substrate 11, the aerosol generating matrix is ​​in the form of a slurry. The aerosol generating matrix can be a liquid with flow properties or a paste. After the slurry dries on the metal substrate 11, it forms the aerosol generating matrix layer 12. During the drying process on the metal substrate 11, the slurry adheres tightly to the metal substrate 11, forming the composite tobacco sheet 1. The composite tobacco sheet 1 is a single, integral structure.

[0077] The composite tobacco sheet 1 of this application embodiment has an aerosol generation matrix layer 12 coated on a metal substrate 11, which allows the composite tobacco sheet 1 to quickly produce smoke without preheating during the heating process.

[0078] 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.

[0079] In one embodiment of this application, the metal substrate 11 is in the form of a sheet.

[0080] In one embodiment of this application, the thickness of the metal substrate 11 is 4 μm-40 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 4 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.

[0081] 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) within 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 influence of the induced EMF, generating induced eddy currents. As 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 aerosol generation matrix layer 12.

[0082] In one embodiment of this application, the metal substrate 11 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.

[0083] In one embodiment of this application, the metal substrate 11 includes a high-nickel alloy, a nickel-iron alloy, stainless steel, or pure iron.

[0084] In one embodiment of this application, the metal substrate 11 includes a material with good thermal conductivity such as aluminum foil, copper foil or silver foil. The heat generated by the heating component of the aerosol generating device is conducted to the aerosol generating matrix layer 12 through the metal substrate, and the aerosol generating matrix layer 12 is heated to generate aerosol.

[0085] In one embodiment of this application, such as Figure 2-3 As shown, 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. In this way, when the metal substrate 11 heats the aerosol generation matrix layer 12, aerosol is generated, and the aerosol can flow from one side of the metal substrate 11 to the other side through the through holes 111.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] In one embodiment of this application, the metal substrate 11 is formed by rolling and deposition.

[0092] In one embodiment of this application, the aerosol-generating matrix layer 12 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.

[0093] 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.

[0094] In one embodiment of this application, the metal substrate 11 is sheet-shaped, and both opposite surfaces of the metal substrate 11 are coated with an aerosol generation matrix layer 12, so that the aerosol generation matrix layers 12 on both sides of the metal substrate 11 can quickly generate aerosol after being heated by the metal substrate 11.

[0095] In one embodiment of this application, the thickness of the aerosol generating matrix layer 12 is 0.15 mm to 1.00 mm. In another embodiment, the thickness of the aerosol generating matrix layer 12 is 0.15 mm to 0.50 mm. In another embodiment, the thickness of the aerosol generating matrix layer 12 is 0.50 mm to 0.80 mm. In yet another embodiment, the thickness of the aerosol generating matrix layer 12 is 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.40 mm, 0.50 mm, 0.65 mm, 0.80 mm, 0.90 mm, or 1.00 mm.

[0096] In one embodiment of this application, such as Figure 5 As shown, a plurality of aerosol generating matrix layers 12 are coated on a metal substrate 11, and the plurality of aerosol generating matrix layers 12 are spaced apart on the surface of the metal substrate 11. In one embodiment of this application, in order to allow the plurality of aerosol generating matrix layers 12 in the composite tobacco sheet 1 to be heated separately, a long strip-shaped through groove may be provided on the metal substrate 11 to separate adjacent aerosol generating matrix layers 12. In one embodiment of this application, in order to allow the plurality of aerosol generating matrix layers 12 in the composite tobacco sheet 1 to be heated separately, a heat-insulating material may also be provided in the through groove of the metal substrate 11 to block the conduction of heat on the metal substrate 11, thereby allowing the aerosol generating matrix layers 12 to be heated in segments, so that the user can obtain a similar taste before and after inhalation.

[0097] In one embodiment of this application, such as Figure 4 As shown, a plurality of metal substrates 11 are correspondingly disposed on an aerosol generating matrix layer 12, and the plurality of metal substrates 11 are spaced apart. In one embodiment of this application, the plurality of metal substrates 11 can be combined by coating with the aerosol generating matrix layer 12 to form a composite tobacco sheet 1, so that the plurality of metal substrates 11 can be heated individually under the action of multiple electromagnetic coils, and the heat generated by each metal substrate 11 will not be transferred to each other, so that the aerosol generating matrix layer 12 can be heated in segments, and the user can obtain a similar taste before and after inhalation.

[0098] In one embodiment of this application, such as Figure 6 As shown, the composite tobacco sheet 1 is wound into a cylindrical shape.

[0099] In one embodiment of this application, such as Figure 7As shown, the metal substrate 11 has a first edge 112 and a second edge 113, and is wound from the first edge 112 to the second edge 113 to wind the composite tobacco sheet 1 into a cylindrical shape. A gap 114 exists between the first edge 112 and the second edge 113. The first edge 112 and the second edge 113 of the metal substrate 11 do not overlap, which makes the temperature field distribution of the metal substrate 11 more uniform and avoids the formation of a low-temperature zone at the overlap of the first edge 112 and the second edge 113 after the first edge 112 and the second edge 113 overlap. This avoids insufficient heating of the aerosol generation matrix layer 12 corresponding to the overlap of the first edge 112 and the second edge 113.

[0100] In one embodiment of this application, the width of gap 114 is 0.1mm-3.0mm. In another embodiment of this application, the width of gap 114 is 0.1mm-1.0mm. In another embodiment of this application, the width of gap 114 is 1.0mm-3.0mm. In another embodiment of this application, the width of gap 114 is 0.1mm-0.5mm. In yet another embodiment of this application, the width of gap 114 is 0.1mm, 0.2mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, or 3mm.

[0101] In one embodiment of this application, such as Figure 8 As shown, the first edge 112 has a first mating structure 1121, and the second edge 113 has a second mating structure 1131. The first mating structure 1121 and the second mating structure 1131 are matched, and a gap 114 is maintained between the edge of the first mating structure 1121 and the edge of the second mating structure 1131.

[0102] In one embodiment of this application, the first mating structure 1121 and the second mating structure 1131 are serrated, wavy, or irregularly shaped. When both the first mating structure 1121 and the second mating structure 1131 are serrated, they are serratedly mated; when both the first mating structure 1121 and the second mating structure 1131 are wavy, they are wavyly mated; and when both the first mating structure 1121 and the second mating structure 1131 are irregularly shaped, they are irregularly shaped.

[0103] One embodiment of this application provides an aerosol generating article 100, such as... Figure 9-10 As shown, it includes a mouthpiece segment 20 and a tobacco segment 10 that are connected to each other. The mouthpiece segment 20 is for the user to hold in their mouth, and the tobacco segment 10 is made of the aforementioned composite tobacco sheet 1 wound together.

[0104] In one embodiment of this application, the mouthpiece segment 20 includes a mouthpiece 201 and a connecting segment 202. The connecting segment 202 is located between the mouthpiece 201 and the tobacco segment 10 and is used to guide the aerosol to the mouthpiece 201. The mouthpiece 201 can be held in the mouth of a user, and the user can suck the aerosol by sucking the mouthpiece 201.

[0105] The aerosol generating article 100 of this application includes a tobacco segment 10 wound from a composite tobacco sheet 1. When the tobacco segment 10 of the aerosol generating article 100 is heated, smoke can be generated quickly without preheating.

[0106] In one embodiment of this application, such as Figure 11 As shown, the tobacco segment 10 includes a support member 2, which is disposed inside the composite tobacco sheet 1. The support member 2 can increase the structural strength of the wound composite tobacco sheet 1 and the structural strength of the aerosol-generated product 100.

[0107] In one embodiment of this application, the support member 2 is tubular. In another embodiment, the support member 2 may be a metal tube, a paper tube, or a ceramic tube. In yet another embodiment, the support member 2 may also have other shapes.

[0108] In one embodiment of this application, the thickness of the support member 2 is 0.1mm-1.0mm. In one embodiment of this application, the thickness of the support member 2 is 0.3mm-0.5mm. In one embodiment of this application, the thickness of the support member 2 is 0.1mm, 0.3mm, 0.5mm, 0.8mm, or 1.0mm.

[0109] In one embodiment of this application, the composite tobacco sheet 1 can be wound around the support member 2 as an axis. In another embodiment of this application, the composite tobacco sheet 1 is wound and then fitted onto the outside of the support member.

[0110] In one embodiment of this application, such as Figure 11 As shown, the support member 2 is provided with ventilation holes 21 that penetrate through both sides of the support member 2, allowing air or aerosol to pass through freely.

[0111] In one embodiment of this application, the ventilation holes 21 are arranged in an ordered or disordered manner. In one embodiment, the ventilation holes 21 may be arranged in an array. In one embodiment, the ventilation holes 21 may be arranged in a circular, elliptical, racetrack-shaped, rectangular, triangular-hexagonal, or other shape. In one embodiment, the ventilation holes 21 may be arranged in a centrally symmetrical or axially symmetrical pattern.

[0112] In one embodiment of this application, the cross-section of the vent hole 21 is circular, polygonal, or irregular. In another embodiment of this application, the cross-section of the vent hole 21 is triangular, rectangular, circular, elliptical, racetrack-shaped, hexagonal, or other irregular.

[0113] In one embodiment of this application, there are multiple vent holes 21, and the opening ratio of the multiple vent holes 21 on the support member 2 is 20%-50%. In one embodiment of this application, the opening ratio of the multiple vent holes 21 on the support member 2 is 20%, 25%, 30%, 35%, 40%, 45%, or 50%.

[0114] In one embodiment of this application, the vent hole 21 is formed by machining or chemical etching. In one embodiment of this application, machining includes drilling or laser processing.

[0115] In one embodiment of this application, such as Figure 13 As shown, a tobacco sheet 3 is disposed between the support member 2 and the composite tobacco sheet 1. It should be noted that the composition of the tobacco sheet 3 is the same as that of the aerosol generating matrix layer 12. The tobacco sheet 3 can be first wrapped around the support member 2, and then the composite tobacco sheet 1 can be wrapped around the outer periphery of the tobacco sheet 3, which can increase the content of tobacco products in the aerosol generating product 100.

[0116] In some examples, the aerosol generation matrix layer 12 on the composite tobacco sheet 1 is in contact with the tobacco sheet 3; in some examples, the metal substrate 11 on the composite tobacco sheet 1 is in contact with the tobacco sheet 3.

[0117] Of course, the order in which the tobacco sheet 3 and the composite tobacco sheet 1 are wrapped is not limited to this. For example, the composite tobacco sheet 1 can be wrapped onto the support member 2 first, and then the tobacco sheet 3 can be wrapped onto the outside of the composite tobacco sheet 1. Alternatively, the composite tobacco sheet 1 and the tobacco sheet 3 can be stacked and then simultaneously rolled or wrapped onto the support member 2 (the stacking order of the composite tobacco sheet 1 and the tobacco sheet 3, and the inside or outside of the wrapping direction are not limited here).

[0118] In one embodiment of this application, such as Figure 12 As shown, the tobacco segment 10 includes a wrapper 4, which is disposed on the outside of the composite tobacco sheet 1. The wrapper 4 can protect the rolled composite tobacco sheet 1 and prevent the aerosol generation matrix layer 12 on the metal substrate 11 from being worn.

[0119] In one embodiment of this application, the package 4 may be a paper tube.

[0120] In one embodiment of this application, the package 4 is an integrally formed tube or a wound tube.

[0121] In one embodiment of this application, when the package 4 is an integrally formed tube, the wound composite tobacco sheet 1 is sleeved inside the package 4. In another embodiment of this application, when the package 4 is a wound tube, the package 4 can be wound together with the composite tobacco sheet 1.

[0122] In one embodiment of this application, when the package 4 is a wound tube, the package 4 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.

[0123] In one embodiment of this application, when the package 4 is a wound tube, the package 4 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.

[0124] In one embodiment of this application, such as Figure 14 As shown, the tobacco segment 10 also includes a protective layer 5, which is disposed between the composite tobacco sheet 1 and the wrapper 4 to prevent the aerosol generation matrix layer 12 from being scratched or worn during the process of loading the composite tobacco sheet 1 into the wrapper 4. In one embodiment of this application, the protective layer 5 can be paper.

[0125] In one embodiment of this application, a tobacco sheet 3 is disposed between the package 4 and the composite tobacco sheet 1, thereby increasing the amount of smoke produced by the aerosol-generating article 100 during inhalation. In this way, the tobacco sheet 3 can separate the metal matrix layer 12 of the composite tobacco sheet 1 from the package 4, preventing the metal matrix layer 12 from directly baking the package 4.
