Description

Technical Field

[0001] This invention belongs to the field of aerosol generating products, specifically relating to an aerosol generating product having a frame-type heat distribution component. Background Technology

[0002] Generating aerosols by heating aerosol-generating materials with electronic devices instead of burning them has gradually become a mainstream aerosol generation method in recent years, replacing traditional lit cigarettes. There are many types of aerosol-generating materials, with tobacco being the most typical example. However, it is not limited to tobacco. Therefore, although this article uses tobacco as an example, aerosol-generating materials actually include many other herbal plants, as these plants can also produce aerosols with unique aromas for users to inhale and enjoy when heated.

[0003] Heated cigarettes, when smoked using electronic heating devices, not only allow consumers to experience the aroma of tobacco, but also significantly reduce the release of tar and harmful substances in the mainstream smoke due to the low-temperature heating process. Compared to traditional cigarettes, they reduce the harmful substances produced by the high-temperature pyrolysis during combustion. However, current heated cigarettes have the following problems:

[0004] To improve the smoke generation efficiency of heated cigarettes, powdered, granular, sheet-like, ring-shaped, or spring-shaped heat-conducting materials are typically added randomly within the smoke generation section. However, most reported cases show that the heat-conducting materials added during the aerosol-forming matrix manufacturing process are randomly distributed internally and not necessarily continuous. Therefore, such heat-conducting materials cannot guarantee uniform heating of the aerosol-forming matrix within the smoke generation section, easily leading to inconsistent puff flavor.

[0005] To address the above problems, this invention is proposed. Summary of the Invention

[0006] The present invention provides an aerosol generating product having a frame-type heat distribution component, the aerosol generating product comprising an aerosol generating component, the aerosol generating component comprising: an aerosol forming matrix and a frame-type heat distribution component;

[0007] The frame-type heat distribution component includes several supporting heat-conducting components, which support each other and have gaps between them, with the aerosol forming matrix inside the gaps.

[0008] The supporting heat-conducting components support each other, creating support points between them. These support points also serve as connection points, allowing multiple supporting heat-conducting components to be connected, thus achieving continuous heat conduction.

[0009] Preferably, the supporting heat-conducting component has a fixed predetermined shape, which remains unchanged after the aerosol generating product is added, and is not a shape that is naturally formed when the aerosol generating product is loaded.

[0010] Preferably, the frame-type heat distribution component is made of a rigid material to ensure that the structure of the frame-type heat distribution component does not undergo significant deformation or breakage when the aerosol forming matrix is ​​loaded into the aerosol generating product, thus ensuring continuous heat conduction.

[0011] Preferably, the shape of the frame-type heat distribution component is axisymmetric.

[0012] Preferably, any transverse cross-section of the frame-type heat distribution component is a centrally symmetrical figure.

[0013] The aforementioned axisymmetric or centrosymmetric design ensures the regularity of the frame-type heat distribution components, thereby achieving a uniform and continuous heat conduction effect within the aerosol generating components.

[0014] Preferably, the supporting heat-conducting component is selected from one or more of the following: radial support rod, axial support rod, and circumferential support ring.

[0015] Preferably, the supporting heat-conducting component is wound with heat-conducting wires. The heat-conducting wires further increase the heat-conducting contact points between the aerosol forming matrix and the frame-type heat distribution component, thus further improving the heat conduction effect.

[0016] Preferably, the frame-type heat distribution component has structurally identical component units in the axial direction. Each component unit contains at least two supporting heat-conducting elements.

[0017] Those skilled in the art can determine the size of the gaps between the supporting heat-conducting components according to their needs and the dimensions of the aerosol-forming matrix. The radial support rods, axial support rods, and circumferential support rings can be freely combined as needed.

[0018] Both radial and axial support rods are straight rods. Of course, other shapes of support rods or support rings are also possible, such as polygonal or spiral shapes.

[0019] Preferably, the aerosol generating product includes an outer casing, the aerosol generating component is housed within the outer casing, and the frame-type heat distribution component has multiple contact points or contact points with the inner wall of the outer casing. Thus, when the aerosol generating product is used in a circumferentially heated aerosol generating device, the frame-type heat distribution component is closer to the circumferential heating element of the circumferentially heated aerosol generating device, resulting in better heat conduction.

[0020] Preferably, the material of the supporting heat-conducting component is selected from one or more of metals, alloys, ceramics, and graphene.

[0021] In another preferred embodiment of the present invention, the supporting heat-conducting element is made of an electromagnetic acceptor material to generate heat under electromagnetic induction. In this case, the supporting heat-conducting element simultaneously possesses both self-heating and heat-conducting effects. A protective layer can be provided on the outer surface of the supporting heat-conducting element to prevent it from being corroded by external factors. The protective layer can also have an insulating function.

[0022] More preferably, an insulating heat-conducting wire is wound around the supporting heat-conducting component. The insulating heat-conducting wire further increases the thermal contact points between the aerosol forming matrix and the frame-type heat distribution component, thus further improving the heat conduction effect. The insulating heat-conducting wire can be made of glass fiber, ceramic fiber, heat-resistant resin fiber, etc.

[0023] Preferably, the electromagnetic acceptor material is selected from one or more of iron, stainless steel, and ferrite.

[0024] As another preferred embodiment of the present invention, the aerosol generating component further includes a supporting heat insulation component;

[0025] Preferably, the shape of the aerosol forming matrix in the aerosol generating component is selected from one or more of the following: granular, powdery, paste-like, filamentous, flake-like, or block-like.

[0026] Preferably, the aerosol generating product further comprises a cooling section and a filtration section disposed downstream of the aerosol generating component.

[0027] Preferably, the outer casing of the aerosol generating product has ventilation holes on its sidewall.

[0028] Preferably, the distal lip of the aerosol generating component is sealed with a breathable or impermeable sealing element.

[0029] The sealing material can be paper, polymer film, organic or inorganic materials, etc.

[0030] In summary, the aerosol generating product of the present invention can be used with a circumferential resistance heating aerosol generating device.

[0031] When the supporting heat-conducting component is made of an electromagnetic acceptor material, the aerosol generating product of the present invention can also be used with an electromagnetic induction heating aerosol generating device.

[0032] The above technical solutions can be freely combined, provided they do not contradict each other.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present invention sets a frame-type heat distribution component in the aerosol generating component, which can realize continuous heat conduction and rapid heat conduction, thereby enabling all aerosol forming matrices to be heated more evenly.

[0035] In addition, the frame structure has the following advantages: (1) It has a certain strength. When the aerosol forming matrix is ​​filled, the frame structure does not deform or break significantly, thus ensuring the continuity of heat conduction; (2) There are gaps between the frame structures to accommodate the aerosol forming matrix, which makes the heat transfer effect of the aerosol forming matrix more uniform.

[0036] 2. When the frame-type heat distribution component is made of electromagnetic acceptor material, the frame-type heat distribution component of the present invention can also generate heat through electromagnetic induction.

[0037] 3. In the preferred embodiment, a heat-conducting wire is wound around the frame-type heat distribution component, which increases the thermal contact points between the aerosol forming matrix and the frame-type heat distribution component, thereby increasing the uniformity of the overall temperature field in the aerosol generating component. When the frame-type heat distribution component is made of an electromagnetic acceptor material, this heat-conducting wire is an insulating heat-conducting wire.

[0038] 4. In this invention, when the aerosol forming matrix is ​​granular, the granular aerosol forming matrix can be evenly distributed in the gaps of the frame-type heat distribution component, thus achieving a better heating effect. Attached Figure Description

[0049] Example 1

[0050] An aerosol generating product with a frame-type heat distribution component includes a tube 1 as an outer casing. The tube 1 contains, sequentially from the distal lip to the proximal lip, an aerosol generating component 3, a multifunctional component 4, and a filter component 5. A sealing element 2 is bonded to the distal lip of the aerosol generating component 3 to seal it. The sealing element 2 is a breathable paper. The aerosol generating component 3 includes a frame-type heat distribution component 3-1 and a particulate aerosol forming matrix 3-2 evenly distributed in the gaps of the frame of the frame-type heat distribution component 3-1.

[0051] In this embodiment, the frame-type heat distribution component 3-1 has an axisymmetric shape, and any transverse cross-section is a centrally symmetrical figure. Specifically, the frame-type heat distribution component 3-1 includes a plurality of supporting heat-conducting components, which support each other and have gaps between them, with the aerosol forming matrix inside the gaps. The frame-type heat distribution component 3-1 is a one-piece structure design, which can be obtained by welding, plugging, bonding, or injection molding.

[0052] The aforementioned supporting heat-conducting components specifically include: four layers of radial support rods 3-1-1, four parallel axial support rods 3-1-2, and four circumferential support rings 3-1-3. The radial support rods 3-1-1 and axial support rods 3-1-2 are arranged perpendicular to each other. The distance between the four layers of radial support rods 3-1-1 is the same. Each layer of radial support rods 3-1-1 contains two intersecting radial support rods 3-1-1. The intersection angle is preferably 90 degrees. The end of each radial support rod 3-1-1 is connected to an axial support rod 3-1-2. The circumferential support rings 3-1-3 are located on the outer periphery of the axial support rods 3-1-2. Each circumferential support ring 3-1-3 has the same height as each layer of radial support rods.

[0053] The aforementioned four layers of radial support rods 3-1-1 and the circumferential support rings 3-1-3 connected to each layer form structurally identical component units in the axial direction.

[0054] The frame-type heat distribution component 3-1 is coaxially arranged with the pipe 1 and contacts the inner wall of the pipe 1 through four circumferential support rings 3-1-3. The outer diameter of the circumferential support rings 3-1-3 is approximately equal to the inner diameter of the pipe 1. The shape of the frame-type heat distribution component is axisymmetric, and any transverse cross-section is a centrally symmetrical figure. The above-mentioned axisymmetric or centrally symmetrical design ensures the regularity of the frame-type heat distribution component, so as to achieve a uniform and continuous heat conduction effect within the aerosol generating component.

[0055] Specifically:

[0056] The axial length of the aforementioned axial support rod 3-1-2 is slightly smaller than the length of the aerosol generating component 3, for example, it is 7 / 8 or 5 / 6 of the length of the aerosol generating component 3. The purpose is to ensure that heat is distributed throughout the axial direction of the aerosol generating component 3 via the axial support rod 3-1-2.

[0057] The purpose of the above-mentioned four radial support rods 3-1-1 and the circumferential support rings 3-1-3 connected to each of them is to ensure that heat is distributed throughout the radial direction of the aerosol generating component 3.

[0058] In this embodiment, the supporting heat-conducting component is made of thermally conductive ceramic. In alternative embodiments, the supporting heat-conducting component can be made of metal, alloy, etc. The supporting heat-conducting component is rigid and therefore has a fixed, predetermined shape. Its shape remains unchanged after the aerosol generating product is added, and it is not a shape that is naturally formed when the aerosol generating product is loaded.

[0059] In this embodiment, the aerosol generating product is particularly suitable for use in a circumferentially heated aerosol generating device. The circumferentially heated aerosol generating device has a circumferential heating element, and a frame-type heat distribution component can evenly transfer the heat from the circumferential heating element to the aerosol forming matrix.

[0060] In an alternative embodiment, the supporting heat-conducting element is made of iron. In this case, the aerosol generating product can be used in electromagnetic induction heating aerosol generating devices, and the supporting heat-conducting element has both self-heating and heat-conducting effects. Furthermore, an insulating heat-conducting wire 6 is wound around the supporting heat-conducting element. The insulating heat-conducting wire 6 can be made of glass fiber.
