Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization technology, and more specifically, to a heating element, an atomizer, and an aerosol generating device. Background Technology
[0002] An aerosol generating device is a small-scale device that uses heating technology to act on an aerosol generating matrix and generate aerosols. It mainly includes two types of devices: those for atomizing solid matrices and those for atomizing liquid matrices. In related technologies, the atomizer in an aerosol generating device includes a heating element, which comprises a substrate and a heating element. The heating element is disposed on the substrate and can heat the aerosol generating matrix within the substrate; or it can indirectly heat the aerosol generating matrix through the substrate to generate aerosols. However, because the heating area of the heating element is relatively large, the heat dissipation area of the heating element is also correspondingly large, causing the heat generated by the heating element to continuously dissipate to the outside, increasing the heat loss of the heating element and reducing its thermal efficiency. Summary of the Invention
[0003] The embodiments of this application provide a heating element, an atomizer, and an aerosol generating device to solve at least one of the aforementioned technical problems.
[0004] The heating element in this embodiment includes a substrate and a heating element. The substrate includes a porous structure and a loading structure. The porous structure has multiple micropores, and the loading structure includes a connecting surface and a heating surface. The connecting surface is used to connect with the porous structure, and the heating surface is used to contact the aerosol generating matrix. The heating element is disposed on the connecting surface or the heating surface, and the heating element is used to heat the aerosol generating matrix to generate aerosols.
[0005] In some embodiments, the plurality of micropores include closed pores that are not interconnected.
[0006] In some embodiments, the plurality of micropores include interconnected vias.
[0007] In some embodiments, the porous structure is made of at least one of metal, ceramic and glass.
[0008] In some embodiments, the size of the porous structure is 0.1 mm to 5.0 mm in the direction from the connecting surface to the heating surface.
[0009] In some embodiments, the loading structure is a porous and loose structure, and the porosity of the loading structure is less than that of the porous structure.
[0010] In some embodiments, the substrate further includes a first dense structure connected to the porous structure and located on opposite sides of the porous structure from the loading structure.
[0011] In some embodiments, the matrix further includes a second dense structure connected to the heating surface and located between the aerosol generating matrix and the heating surface.
[0012] In some embodiments, the thermal conductivity of the porous structure is lower than that of the loading structure.
[0013] In some embodiments, the heating element further includes a glaze layer disposed on the surface of the substrate.
[0014] In some embodiments, the substrate is a tubular structure.
[0015] In some embodiments, the substrate includes a first end and a second end opposite each other in the axial direction of the substrate; the heating element further includes a first connector disposed at the first end of the substrate, the first connector having a thermal conductivity less than that of the loading structure.
[0016] In some embodiments, the substrate includes a first end and a second end opposite each other in the axial direction of the substrate; the heating element further includes a second connector disposed at the second end of the substrate, the second connector having a thermal conductivity less than that of the loading structure.
[0017] In some embodiments, the substrate is a flat plate structure.

[0021] In the heating element, atomizer, and aerosol generating device of this application, the porous structure has multiple micropores. Therefore, the porous structure has a low thermal conductivity and a good heat insulation effect. The heating element is disposed on the connecting surface or heating surface. As a result, the heat generated by the heating element is blocked by the porous structure and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element, reducing the energy consumption of the aerosol generating device, and extending the operating time of the aerosol generating device.

[0055] In related technologies, the atomizer in an aerosol generating device includes a heating element, which comprises a substrate and a heating component. The heating component is disposed on the substrate and is capable of heating the aerosol generating matrix within the substrate; or it indirectly heats the aerosol generating matrix through the substrate to generate aerosols. However, because the heating area of the heating element is relatively large, its heat dissipation area is also correspondingly large, causing the heat generated by the heating component to continuously dissipate to the outside, increasing heat loss and reducing the thermal efficiency of the heating component. To solve this problem, please refer to [link to relevant documentation]. Figure 1 and combined Figures 2 to 4 , Figures 5 to 7 , Figures 8 to 9 , Figures 10 to 11 , Figures 12 to 13 , Figures 14 to 15 , Figures 16 to 17 , Figure 18 ,or Figure 19 This application provides a heating element 10, an atomizer 100, and an aerosol generating device 1000.
[0056] Please see Figure 1 The aerosol generating device 1000 provided in this application includes an atomizer 100 and an electronic control component 300, with the atomizer 100 and the electronic control component 300 being electrically connected.
[0057] It is understood that the aerosol generating apparatus 1000 is a structure capable of generating aerosols by heating an aerosol generating matrix. The aerosol generating matrix is a processed product that, when heated, can generate aerosols. The aerosol generating matrix can be liquid, fully solid, or semi-solid. For example, when the aerosol generating matrix is fully solid, it can be in the form of sheets or columns. The aerosol generating matrix can be prepared using processes such as rolling, slurry preparation, die casting, or extrusion. The aerosol can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor.
[0058] In some embodiments, the electronic control component 300 includes a power supply unit and a controller. The power supply unit provides electrical energy to the atomizer 100 to heat the atomized aerosol generating matrix and form an aerosol. The controller is electrically connected to the power supply unit and controls the operation of the atomizer 100 (including starting and stopping the atomizer 100 and switching operating modes). For example, when the aerosol generating device 1000 is being inhaled, the controller can control the power supply unit to supply power to the atomizer 100. In this case, the electrical energy from the power supply unit can be transferred to the atomizer 100 to enable the atomizer 100 to operate and heat the atomized aerosol generating matrix. When the user is not using the aerosol generating device 1000, the atomizer 100 stops heating the aerosol generating matrix. It should be noted that in some embodiments, the power supply unit can be a dry cell battery, a rechargeable battery, or a capacitor. Rechargeable batteries include, but are not limited to, lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.
[0059] Furthermore, in some embodiments, the aerosol generating device 1000 also includes a housing 500, in which the atomizer 100 and the electronic control assembly 300 are all disposed.
[0060] Specifically, the housing 500 is a structure in the aerosol generating device 1000 that houses and protects the atomizer 100 and other devices. The housing 500 is made of materials including, but not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composites. In one example, the housing 500 can be made of plastic, making it lighter and facilitating the portability of the aerosol generating device 1000. In another example, the housing 500 can be made of a high-temperature resistant material, preventing damage (such as deformation) caused by heat and ensuring the stability and reliability of the aerosol generating device 1000. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.
[0061] Since the aerosol generating device 1000 in this embodiment includes an atomizer 100, it is understood that the aerosol generating device 1000 has at least the same beneficial effects as the atomizer 100. Therefore, for the beneficial effects of the aerosol generating device 1000, please refer to the beneficial effects of the atomizer 100 described below.
[0062] Please see Figure 1 The atomizer 100 provided in this embodiment includes a heating element 10. Since the atomizer 100 in this embodiment includes a heating element 10, it is understood that the atomizer 100 has at least the same beneficial effects as the heating element 10. Therefore, for the beneficial effects of the atomizer 100, please refer to the beneficial effects of the heating element 10 described below.
[0063] Please see Figure 1 and combined Figures 2 to 4 , Figures 5 to 7 , Figures 8 to 9 , Figures 10 to 11 , Figures 12 to 13 , Figures 14 to 15 , Figures 16 to 17 , Figure 18 ,or Figure 19 The heating element 10 of this embodiment includes a substrate 11 and a heating element 13. The substrate 11 includes a porous structure 111 and a loading structure 113. The porous structure 111 has a plurality of micropores 1111. The loading structure 113 includes a connecting surface 1131 and a heating surface 1133. The connecting surface 1131 is used to connect with the porous structure 111, and the heating surface 1133 is used to contact the aerosol generating matrix. The heating element 13 is disposed on the connecting surface 1131 or the heating surface 1133, and the heating element 13 is used to heat the aerosol generating matrix to generate aerosol.
[0064] The substrate 11 is a structure within the heating element 10 used to house components other than the substrate 11. The outer contour of the substrate 11 can be regular or irregular. Regular shapes, as used herein, include, but are not limited to, rectangles, circles, cylinders, triangles, and polygons. When the outer contour of the substrate 11 is irregular, the heating element 10 can adapt to the structural layout of the atomizer 100, facilitating the compact arrangement of other components. In some embodiments of this application, the substrate 11 includes a porous structure 111 and a loading structure 113. The shapes of the porous structure 111 and the loading structure 113 can be approximately the same, thus making the overall structure of the substrate 11 more regular and facilitating its assembly within the atomizer 100.
[0065] The porous structure 111 is the main structure in the matrix 11 used to prevent heat dissipation. In some embodiments of this application, the porous structure 111 has multiple micropores 1111, that is, there are multiple spaces inside the porous structure 111 that are not filled by solid material. The presence of micropores 1111 makes the heat transfer path more complex and tortuous, increases the resistance to heat transfer, and reduces the thermal conductivity of the porous structure 111. Furthermore, since there is gas in the micropores 1111, and the thermal conductivity of gas is lower than that of solid material, the gas in the micropores 1111 can also hinder heat transfer, thus making the porous structure 111 have a better thermal insulation effect. It should be noted that in some embodiments, the multiple micropores 1111 include closed pores that are not interconnected.
[0066] It is understandable that the loading structure 113 preferably uses a material with low thermal conductivity, such as less than 2 W / m*K. -1 Materials.
[0067] In some embodiments of this application, the connecting surface 1131 of the loading structure 113 can be connected to the porous structure 111 to jointly form the substrate 11; the heating surface 1133 can contact the aerosol generating matrix, so that the heat generated by the heating element 13 can act on the aerosol generating matrix through the heating surface 1133, so that the aerosol generating matrix is heated to generate aerosols. The aerosol generating matrix in this document includes, but is not limited to, liquid matrix, solid matrix, or paste matrix.
[0068] In some embodiments, the porous structure 111 and the loading structure 113 are an integral structure, that is, the porous structure 111 and the loading structure 113 are an integral structure manufactured by an integral molding process. This can improve the bonding strength between the porous structure 111 and the loading structure 113, prevent the porous structure 111 and the loading structure 113 from separating during the operation of the heating element 10, and improve the stability and reliability of the operation of the heating element 10. In other embodiments, the porous structure 111 and the loading structure 113 are separate structures, that is, the porous structure 111 and the loading structure 113 are two different structures. The connecting surfaces 1131 of the porous structure 111 and the loading structure 113 can be joined together by a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, bolt connections or snap-fit connections; non-detachable connection methods include, but are not limited to, adhesive or welding.
[0069] The heating element 13 is a structure in the heating body 10 used to heat the aerosol generation matrix. In some embodiments of this application, the heating element 13 includes, but is not limited to, heating circuits, heating films, heating sheets, heating wires, and heating meshes. The heating circuits can be PVD thin films or printed thick films. The heating element 13 can be made of a metal material with appropriate impedance, such as at least one of silver, silver palladium, platinum, gold, copper, nickel, aluminum, tungsten, 430, 316L, and FeCrAl; the heating element 13 can also be made of metal composite materials, such as at least one of cermet, metallic glass, and conductive ceramics. It should be noted that in some embodiments, the heating element 13 may have certain antioxidant properties.
[0070] For example, please refer to Figures 5 to 7 The heating element 13 is a heating wire, which is spiral-shaped. For example, a user can wind the heating wire into a spiral shape using a spring winding machine. The heating element 10 also includes a first electrical connector 14 and a second electrical connector 15, which are electrically connected to opposite ends of the heating wire and can form a circuit loop with the electronic control component 300. For example, when both the first electrical connector 14 and the second electrical connector 15 are electrically connected to the electronic control component 300, electrical energy from the electronic control component 300 can flow through the first electrical connector 14 to the heating wire to generate heat, and electrical energy can flow back from the heating wire to the electronic control component 300 through the second electrical connector 15.
[0071] In some embodiments, the heating element 13 is disposed on the connecting surface 1131, thereby preventing direct contact between the heating element 13 and the aerosol generating matrix. This reduces the likelihood of corrosion of the heating element 13, extends its service life, and ensures the normal operation of the heating element 10. Furthermore, it prevents aerosols generated by the aerosol generating matrix from contacting the heating element 13, avoiding condensation and the formation of black charred material, thus ensuring a better suction experience for the user. Additionally, compared to the side of the substrate 11 away from the aerosol generating matrix, i.e., compared to the side of the porous structure 111 opposite to the loading structure 113, the heating element 13 is closer to the aerosol generating matrix, resulting in a faster heat transfer rate, increased heating rate of the aerosol generating matrix, reduced suction waiting time, and improved suction experience for the user.
[0072] In other embodiments, the heating element 13 is disposed on the heating surface 1133. Thus, compared to the side of the substrate 11 away from the aerosol generating matrix, that is, compared to the side of the porous structure 111 opposite to the loading structure 113, the heating element 13 can directly heat the aerosol generating matrix, resulting in a faster heat transfer rate. This further improves the heating rate of the aerosol generating matrix, reduces the suction waiting time, and generates aerosols faster, thus improving the user's suction experience.
[0073] In some other embodiments, the heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133, that is, the heating element 13 is embedded in the loading structure 113. This reduces the possibility of interference damage between the heating element 13 and the external structure, thereby extending the service life of the heating element 13 and ensuring the stability and reliability of the heating element 10. On the other hand, it reduces the space occupied by the heating element 13, which is beneficial to the miniaturization of the heating element 10.
[0074] In addition, the heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133, which can also enable the heat generated by the heating element 13 to act more on the aerosol generating matrix. This can enhance the heating effect on the aerosol generating matrix and ensure the user's inhalation experience. On the other hand, it can reduce the possibility of heat dissipation to other structural components of the aerosol generating device 1000 (such as the shell), reduce the outer wall temperature of the aerosol generating device 1000, and improve the user's experience.
[0075] In the heating element 10 of this application embodiment, the porous structure 111 has multiple micropores 1111. Therefore, the porous structure 111 has a low thermal conductivity and a good heat insulation effect. The heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133. As a result, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13, reducing the energy consumption of the aerosol generating device 1000, and extending the operating time of the aerosol generating device 1000.
[0076] The heating element 10 will be further explained below with reference to the accompanying drawings.
[0077] Please see Figures 2 to 4 , Figures 5 to 7 , Figures 8 to 9 , Figures 10 to 11 , Figures 12 to 13 , Figures 14 to 15 , Figures 16 to 17 , Figure 18 ,or Figure 19In some embodiments, the porous structure 111 is made of at least one of metal, ceramic, and glass. It is understood that the porous structure 111 can also be made of composite materials of various materials.
[0078] For example, the porous structure 111 is made of porous ceramic. The porous ceramic can be prepared by mixing a ceramic slurry with a pore-forming agent and then sintering it. The sintered ceramic body has a large number of pores, which are the micropores 1111 of the porous structure 111 described herein. It is understood that in some embodiments, the micropores 1111 in the porous structure 111 can also be artificially created holes. For example, the user can use laser drilling or mechanical drilling to punch holes in the porous structure 111 to form the micropores 1111.
[0079] In some embodiments, the size of the porous structure 111 in the direction from the connecting surface 1131 to the heating surface 1133 is 0.1 mm to 5.0 mm. Specifically, in some embodiments, the size of the porous structure 111 is any one of 0.1 mm, 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, and 5.0 mm, or any value between any two of these values.
[0080] If the size of the porous structure 111 is less than 0.1 mm in the direction from the connecting surface 1131 to the heating surface 1133, the thermal insulation effect of the porous structure 111 is poor and its strength is low, resulting in greater heat loss of the heating element 13 and reducing its thermal efficiency. If the size of the porous structure 111 is greater than 5.0 mm in the direction from the connecting surface 1131 to the heating surface 1133, the size of the porous structure 111 is too large, which is not conducive to the miniaturization of the heating element 10. In some embodiments of this application, the size of the porous structure 111 is 0.1 mm to 5.0 mm. This ensures that the porous structure 111 has a better thermal insulation effect, reduces heat loss, and improves the thermal efficiency of the heating element 13. It also prevents the size of the porous structure 111 from being too large, which is beneficial to the miniaturization of the heating element 10. Furthermore, it ensures the structural strength of the porous structure 111 and improves the stability of the heating element 10.
[0081] In some embodiments, the loading structure 113 is a porous and loose structure.
[0082] Specifically, in some embodiments, the loading structure 113 is a porous and loose structure, that is, the loading structure 113 has multiple micropores. Therefore, the loading structure 113 can also serve as a heat insulation function, thereby further reducing heat loss, improving the thermal efficiency of the heating element 13, reducing the energy consumption of the aerosol generating device 1000, and extending the operating time of the aerosol generating device 1000. For example, when the loading structure 113 is a porous and loose structure, the heating element 13 can be disposed on the heating surface 1133. In this way, the heat dissipation path to the outside will be blocked by the loading structure 113 and the porous structure 111, thereby further reducing heat loss and improving the thermal efficiency of the heating element 13.
[0083] Furthermore, in some embodiments, when the loading structure 113 is a porous structure, the porosity of the loading structure 113 is less than that of the porous structure 111. This ensures the thermal conductivity of the loading structure 113, so that when the heating element 13 is disposed on the connecting surface 1131, the heat generated by the heating element 13 can be conducted to the aerosol generating matrix through the loading structure 113, ensuring the heating effect of the heating element 10 on the aerosol generating matrix and ensuring the user's inhalation experience.
[0084] In other embodiments, the loading structure 113 is a dense structure.
[0085] Specifically, in some embodiments, the loading structure 113 is a dense structure, that is, the loading structure 113 does not have micropores. This ensures the thermal conductivity of the loading structure 113, facilitating the conduction of heat generated by the heating element 13 within the loading structure 113. This improves overall temperature uniformity, ensures the heating effect of the heating element 13 on the aerosol generating matrix, and enhances the user's suction experience. For example, the loading structure 113 can be a dense ceramic, which can be made of at least one of aluminum nitride, silicon carbide, alumina, zirconium oxide, and silicon nitride. This ensures the thermal conductivity of the loading structure 113, reduces heat loss during heat conduction, and allows the temperature of the aerosol generating matrix to meet its atomization requirements more quickly, improving atomization efficiency.
[0086] In some embodiments, the loading structure 113 is made of at least one of metal, ceramic, and glass. It is understood that the loading structure 113 may also be made of composite materials of various materials.
[0087] For example, when the loading structure 113 has a porous structure, the material of the loading structure 113 is porous ceramic. The porous ceramic can be prepared by mixing a ceramic slurry with a pore-forming agent and then sintering it. The sintered ceramic body has a large number of pores, which are the micropores of the loading structure 113 described herein. It is understood that in some embodiments, when the loading structure 113 has a porous structure, the micropores in the loading structure 113 can also be artificially created holes. For example, the user can use laser drilling or mechanical drilling to punch holes in the loading structure 113 to form micropores.
[0088] In some embodiments, the size of the loading structure 113 in the direction from the connecting surface 1131 to the heating surface 1133 is 0.02mm-1.0mm. Specifically, in some embodiments, the size of the loading structure 113 is any one of 0.02mm, 0.03mm, 0.05mm, 0.1mm, 0.5mm, and 1.0mm, or any value between any two of these values.
[0089] Since the heating element 13 is located on the connecting surface 1131, the heat generated by the heating element 13 needs to be transferred to the aerosol generating matrix through the loading structure 113. However, the loading structure 113 itself absorbs a certain amount of heat due to its specific heat capacity, and the amount of heat absorbed is positively correlated with the volume and density of the loading structure 113. If the dimension of the loading structure 113 is greater than 1.0 mm in the direction from the connecting surface 1131 to the heating surface 1133, the loading structure 113 absorbs more heat, resulting in less heat being transferred to the aerosol generating matrix. Consequently, the heating element 10 needs a longer time to reach the atomization temperature of the aerosol generating matrix, affecting the atomization efficiency. If the dimension of the loading structure 113 is less than 0.02 mm in the direction from the connecting surface 1131 to the heating surface 1133, the strength of the loading structure 113 is too low, making it prone to damage (e.g., deformation or breakage), affecting the normal operation of the heating element 10. In some embodiments of this application, the size of the loading structure 113 in the direction from the connecting surface 1131 to the heating surface 1133 is 0.02mm-1.0mm. This can prevent the size of the loading structure 113 from being too large and affecting heat transfer, thereby ensuring atomization efficiency. On the other hand, it can avoid the problem that the loading structure 113 is easily damaged due to its low strength, thereby ensuring the normal operation of the heating element 10. Furthermore, it can prevent the size of the loading structure 113 from being too large, which is conducive to the miniaturization of the heating element 10.
[0090] In some embodiments, the temperature coefficient of resistance (TCR) of the heating element 13 is greater than or equal to 1000 ppm / K. Specifically, in some embodiments, the temperature coefficient of resistance of the heating element 13 is any value greater than or equal to 1000 ppm / K, such as 1000 ppm / K, 1100 ppm / K, 1200 ppm / K, 1300 ppm / K, 1400 ppm / K, 1500 ppm / K, 1600 ppm / K, 1700 ppm / K, 1800 ppm / K, 1900 ppm / K, and 2000 ppm / K, or any value between any two values greater than or equal to 1000 ppm / K.
[0091] The heating element 13 has a resistance temperature coefficient greater than or equal to 1000ppm / K, which enables it to achieve automatic temperature control. That is, because the resistance of the heating element 13 increases with temperature, its heating power decreases as the temperature rises during constant pressure operation, eventually settling at a predetermined temperature. This allows the heating element 13 to achieve automatic temperature control without the need for additional temperature sensors and control circuits. This prevents damage to the heating element 13 due to overheating, extending its service life and ensuring the safe operation of the aerosol generator 1000. Furthermore, it prevents the aerosol generation matrix from burning due to overheating, ensuring a better inhalation experience for the user.
[0092] In some embodiments, the heating element 13 includes a plurality of heating elements 13 arranged in parallel. When the heating element 10 is working, at least one of the plurality of heating elements 13 generates heat to heat the aerosol to generate a matrix.
[0093] Specifically, in some embodiments, the heating element 10 further includes a first electrical connector 14 and a second electrical connector 15. Both the first electrical connector 14 and the second electrical connector 15 are electrically connected to the heating element 13 and can form a circuit loop together with the electronic control component 300. For example, electrical energy from the electronic control component 300 can flow to the heating element 13 through the first electrical connector 14 to generate heat in the heating element 13, and electrical energy can flow back from the heating element 13 to the electronic control component 300 through the second electrical connector 15.
[0094] When the heating element 10 is working, at least one of the multiple heating elements 13 is energized to heat the aerosol generating matrix. That is, the multiple heating elements 13 can operate independently, in combination, or alternately to generate various heating powers to heat the aerosol generating matrix, thereby increasing the number of power levels of the heating element 10 and effectively meeting user needs. Furthermore, the multiple heating elements 13 can heat and atomize the aerosol generating matrix through independent or alternating operation. During this time, some of the heating elements 13 can be in a non-operating state. This allows the non-operating heating elements 13 to cool down, preventing overheating damage from prolonged operation and extending their service life, thus ensuring the stability and reliability of the heating element 10.
[0095] Please combine Figures 2 to 4 ,or Figure 10 and Figure 11 In some embodiments, the first electrical connector 14 includes multiple first electrical connectors 14, each of which is electrically connected to a corresponding plurality of heating elements 13; the second electrical connector 15 includes one second electrical connector 15, which is electrically connected to all of the heating elements 13, thus enabling the multiple heating elements 13 to be arranged in parallel. It should be noted that in this embodiment, the heating element 13 can be a heating circuit.
[0096] Please combine Figure 8 and Figure 9 In other embodiments, the first electrical connector 14 includes multiple components, each of which is electrically connected to a corresponding heating element 13; the second electrical connector 15 includes multiple components, each of which is electrically connected to a corresponding heating element 13, thus enabling the multiple heating elements 13 to be connected in parallel. It should be noted that in this embodiment, the heating element 13 can be a heating mesh.
[0097] Please combine Figure 19 In some embodiments, the substrate 11 further includes a first dense structure 115, which is connected to the porous structure 111 and is located on opposite sides of the loading structure 113.
[0098] Specifically, in some embodiments, the first dense structure 115 has fewer micropores, or even no micropores at all. The presence of the first dense structure 115 increases the resistance to heat dissipation to the outside, thereby further reducing heat loss, improving the thermal efficiency of the heating element 10, reducing the energy consumption of the aerosol generating device 1000, and extending the operating time of the aerosol generating device 1000. In addition, the first dense structure 115 also provides structural support, thereby reducing the possibility of deformation and damage to the substrate 11, and ensuring the stability and reliability of the heating element 10. It should be noted that in this embodiment, the multiple micropores 1111 in the porous structure 111 include interconnected connecting holes.
[0099] In some embodiments, the first dense structure 115 and the porous structure 111 can be combined using either a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, bolted connections or snap-fit connections; non-detachable connection methods include, but are not limited to, adhesive bonding or welding.
[0100] In some embodiments, the substrate 11 further includes a second dense structure 117, which is connected to the heating surface 1133 and located between the aerosol generating matrix and the heating surface 1133.
[0101] Specifically, in some embodiments, the second dense structure 117 has fewer micropores, or even no micropores; the thermal conductivity of the second dense structure 117 is greater than or equal to the thermal conductivity of the loading structure 113. The arrangement of the second dense structure 117 enables more uniform heating of the aerosol generating matrix, thereby ensuring uniform atomization of the aerosol generating matrix and better consistency in taste; it also prevents uneven heating in different areas of the aerosol generating matrix, which could lead to a burnt taste in the generated aerosol, thus improving the user's inhalation experience. Furthermore, the second dense structure 117 also provides structural support, reducing the possibility of deformation and damage to the substrate 11, and ensuring the stability and reliability of the heating element 10. It is understood that in some embodiments, the heating element 13 may also be located on the side of the second dense structure 117 opposite to the loading structure 113.
[0102] In some embodiments, the second dense structure 117 and the loading structure 113 can be combined using either a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, bolted connections or snap-fit connections; non-detachable connection methods include, but are not limited to, adhesive bonding or welding.
[0103] In some embodiments, the thermal conductivity of the porous structure 111 is lower than that of the loading structure 113, thereby reducing heat loss and concentrating the heat generated by the heating element 13 on the heating surface 1133 to heat the aerosol generating matrix. This improves the thermal efficiency of the heating element 13, reduces the energy consumption of the aerosol generating device 1000, and extends the operating time of the aerosol generating device 1000. Furthermore, the higher thermal conductivity of the loading structure 113 also improves the temperature uniformity of the heating surface 1133, ensuring uniform heating of the aerosol generating matrix and guaranteeing a consistent taste and better user experience during inhalation.
[0104] In some embodiments, the heating element 10 further includes a glaze layer disposed on the surface of the substrate 11.
[0105] Specifically, in some embodiments, in the direction from the connecting surface 1131 to the heating surface 1133, the substrate 11 includes a first side and a second side facing away from each other, and a glaze layer can be disposed on the first side and / or the second side of the substrate 11. The glaze layer can improve the high-temperature stability and anti-peeling properties of the substrate 11, thereby improving the stability and reliability of the heating element 10. It should be noted that in some embodiments, the glaze layer can be formed on the surface of the substrate 11 by high-temperature sintering using methods such as dip coating or screen printing; the material of the glaze layer can include SiO2, and other oxides.
[0106] Please see Figures 2 to 4 , Figures 5 to 7 , Figures 8 to 9 , Figures 10 to 11 , Figure 18 ,or Figure 19 In some embodiments, the substrate 11 is a tubular structure. That is, the substrate 11 can be a generally hollow columnar structure. Wherein, the substrate 11 has a hollow cavity, and in this case, the cross-sectional shape of both the porous structure 111 and the loading structure 113 can be annular. It is understood that the porous structure 111 is the outer layer structure of the substrate 11, and the loading structure 113 is the inner layer structure of the substrate 11, so that the heating surface 1133 can contact the aerosol-generating matrix in the hollow cavity.
[0107] In some embodiments, the thermal conductivity of the porous structure 111 is lower than that of the loading structure 113, thereby reducing heat loss and concentrating the heat generated by the heating element 13 on the heating surface 1133 to heat the aerosol generating matrix. This improves the thermal efficiency of the heating element 13, reduces the energy consumption of the aerosol generating device 1000, and extends the battery life of the aerosol generating device 1000. Furthermore, the higher thermal conductivity of the loading structure 113 also improves the temperature uniformity of the heating surface 1133, ensuring uniform heating of the aerosol generating matrix and guaranteeing a better consistency in taste and user experience during inhalation.
[0108] In other embodiments, the thermal conductivity of the porous structure 111 is greater than that of the loading structure 113. In this case, the heating element 13 is disposed on the heating surface 1133. Thus, the heat generated by the heating element 13 is difficult to conduct to the outside through the loading structure 113 and the porous structure 111, thereby further reducing heat loss. The heat generated by the heating element 13 is concentrated on the heating surface 1133 to heat the aerosol generation matrix, thereby improving the thermal efficiency of the heating element 13, reducing the energy consumption of the aerosol generation device 1000, and extending the battery life of the aerosol generation device 1000.
[0109] Please combine Figure 10 and Figure 11 In some embodiments, the substrate 11 includes a first end 101 and a second end 103 opposite each other in the axial direction of the substrate 11; the heating element 10 also includes a first connector 16 disposed at the first end 101 of the substrate 11, and the thermal conductivity of the first connector 16 is less than the thermal conductivity of the loading structure 113.
[0110] Specifically, please combine Figure 1 In some embodiments, the first connector 16 is used to connect the base 11 and an external structure (e.g., the housing 500 or other structural components within the housing 500). The thermal conductivity of the first connector 16 is lower than that of the loading structure 113. Therefore, the first connector 16 provides thermal insulation between the first end 101 of the base 11 and the external structure, preventing heat transfer to the external structure. This reduces heat dissipation, improves the thermal efficiency of the heating element 13, and lowers the energy consumption of the aerosol generating device 1000. Furthermore, it concentrates the temperature, enhancing the heating effect of the heating element 13 on the aerosol generating matrix and ensuring a better inhalation experience for the user.
[0111] In some embodiments, the first connector 16 and the base 11 are an integral structure, that is, the first connector 16 and the base 11 are an integral structure manufactured by an integral molding process. This can improve the bonding strength between the first connector 16 and the base 11, prevent the first connector 16 and the base 11 from separating during the operation of the heating element 10, and improve the stability and reliability of the operation of the heating element 10. In other embodiments, the first connector 16 and the base 11 are separate structures, that is, the first connector 16 and the base 11 are two different structures. The connecting surfaces 1131 of the first connector 16 and the base 11 can be joined together by a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, bolt connections or snap-fit connections; non-detachable connection methods include, but are not limited to, adhesive or welding.
[0112] In some embodiments, the substrate 11 includes a first end 101 and a second end 103 opposite each other in the axial direction of the substrate 11; the heating element 10 also includes a second connector 17 disposed at the second end 103 of the substrate 11, and the thermal conductivity of the second connector 17 is less than that of the loading structure 113.
[0113] Specifically, in some embodiments, the second connector 17 is used to connect the base 11 and an external structure (e.g., the housing 500 or other structural components within the housing 500). The thermal conductivity of the second connector 17 is lower than that of the loading structure 113. Therefore, the second connector 17 provides thermal insulation between the second end 103 of the base 11 and the external structure, preventing heat transfer to the external structure. This reduces heat dissipation, improves the thermal efficiency of the heating element 13, and lowers the energy consumption of the aerosol generating device 1000. Furthermore, it concentrates the temperature, enhancing the heating effect of the heating element 13 on the aerosol generating matrix and ensuring a better inhalation experience for the user.
[0114] In some embodiments, the second connector 17 and the base 11 are an integral structure, that is, the second connector 17 and the base 11 are an integral structure manufactured by an integral molding process. This can improve the bonding strength between the second connector 17 and the base 11, prevent the second connector 17 and the base 11 from separating during the operation of the heating element 10, and improve the stability and reliability of the heating element 10. In other embodiments, the second connector 17 and the base 11 are separate structures, that is, the second connector 17 and the base 11 are two different structures. The connecting surfaces 1131 of the second connector 17 and the base 11 can be joined together by a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, bolt connections or snap-fit connections; non-detachable connection methods include, but are not limited to, adhesive or welding.
[0115] Please see Figure 12 and Figure 13 , Figure 14 and Figure 15 ,or Figure 16 and Figure 17 In other embodiments, the substrate 11 is a plate-like structure. That is, the substrate 11 can be a plate-like structure with a certain thickness and area. The porous structure 111 and the loading structure 113 are stacked. For example, both the porous structure 111 and the loading structure 113 can have a square cross-sectional shape.
[0116] In some embodiments, the thermal conductivity of the porous structure 111 is lower than that of the loading structure 113, thereby reducing heat loss and concentrating the heat generated by the heating element 13 on the heating surface 1133 to heat the aerosol generating matrix. This improves the thermal efficiency of the heating element 13, reduces the energy consumption of the aerosol generating device 1000, and extends the operating time of the aerosol generating device 1000. In other embodiments, the thermal conductivity of the porous structure 111 is approximately the same as that of the loading structure 113. In this case, the aerosol generating matrix does not contact the heating surface 1133.
[0117] Please combine Figure 12 and Figure 13 In some embodiments, the heating element 10 further includes a storage component 19, which is disposed on the heating surface 1133 and used to store the aerosol generation matrix. The storage component 19 has a porous and loose structure. It should be noted that, in some embodiments, the aerosol generation matrix stored in the storage component 19 may be a liquid matrix or a paste matrix.
[0118] Specifically, in some embodiments, in the aerosol generating device 1000 ( Figure 1 When the aerosol is being drawn in (as shown), the heat generated by the heating element 13 can be conducted to the storage element 19 to heat the aerosol generating matrix in the storage element 19, thereby generating aerosol for the user to draw in. For example, the storage element 19 can be a porous ceramic, where the micropores can store and conduct the aerosol generating matrix under capillary action. Porous ceramics are typically prepared by mixing ceramic slurry with a pore-forming agent and then sintering, resulting in a large number of micropores within the sintered ceramic body.
[0119] It is understood that the technical features mentioned above can be combined to form various implementations of the heating element 10. Some possible implementations of this application are illustrated below:
[0120] Implementation Method 1
[0121] Please see Figure 18 (a) In this embodiment, the heating element 10 has a tubular structure and includes a porous structure 111 and a loading structure 113. The loading structure 113 has a dense structure. The heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133.
[0122] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1(As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.
[0123] Implementation Method 2
[0124] Please see Figure 18 (b) In this embodiment, the heating element 10 has a tubular structure, including a porous structure 111 and a loading structure 113. The loading structure 113 has a porous and loose structure. The thermal conductivity of the porous structure 111 is less than that of the loading structure 113; the porosity of the loading structure 113 is less than that of the porous structure 111; the heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133.
[0125] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 The energy consumption (as shown) is reduced, extending the operating time of the aerosol generating device 1000. Furthermore, since the loading structure 113 is a porous structure and the heating element 13 is disposed on the heating surface 1133, the loading structure 113 can also serve as a heat insulation layer, thereby further reducing heat loss, improving the thermal efficiency of the heating element 13, reducing the energy consumption of the aerosol generating device 1000, and extending the operating time of the aerosol generating device 1000.
[0126] Implementation Method 3
[0127] Please see Figure 19 (a) In this embodiment, the heating element 10 is a tubular structure, comprising a porous structure 111, a loading structure 113, a first dense structure 115, and a second dense structure 117. The loading structure 113 is a porous and loose structure. The porosity of the loading structure 113 is less than that of the porous structure 111. The heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133. The heating element 13 may also be disposed on the side of the second dense structure 117 opposite to the loading structure 113.
[0128] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 (As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.
[0129] Furthermore, the first dense structure 115 increases the resistance to heat dissipation to the outside. That is, while the heat generated by the heating element 13 is dissipated to the outside through the porous structure 111, the heat still needs to pass through the first dense structure 115, thereby further reducing heat loss, improving the thermal efficiency of the heating element 10, reducing the energy consumption of the aerosol generating device 1000, and extending the battery life of the aerosol generating device 1000. The second dense structure 117 enables more uniform heating of the aerosol generating matrix. This allows the aerosol generating matrix to be uniformly atomized, resulting in a better consistency in taste; it also prevents uneven heating of different areas of the aerosol generating matrix, which could lead to a burnt taste in the generated aerosol, thus improving the user's vaping experience.
[0130] Implementation Method 4
[0131] Please see Figure 19 (b) The heating element 10 in this embodiment is a tubular structure. The heating element 10 includes a porous structure 111, a loading structure 113, a first dense structure 115 and a second dense structure 117. The loading structure 113 is a dense structure. The thermal conductivity of the porous structure 111 is less than that of the loading structure 113. The heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133. The heating element 13 may also be disposed on the side of the second dense structure 117 opposite to the loading structure 113.
[0132] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 The energy consumption (as shown) is reduced, extending the runtime of the aerosol generating device 1000. It is understood that the structure and function of the first dense structure 115 and the second dense structure 117 in this embodiment are basically the same as those in Embodiment 3. Please refer to the above description for details, which will not be repeated here.
[0133] Implementation Method 5
[0134] Please see Figure 19 (c) In this embodiment, the heating element 10 has a tubular structure and includes a porous structure 111, a loading structure 113, a first dense structure 115, and a second dense structure 117. The loading structure 113 has a porous and loose structure. The porosity of the loading structure 113 is approximately the same as that of the porous structure 111. The heating element 13 is disposed between the connecting surface 1131 and the heating surface 1133. The heating element 13 may also be disposed on the side of the second dense structure 117 opposite to the loading structure 113.
[0135] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 (As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.
[0136] Furthermore, when the loading structure 113 is a porous and loose structure, and the heating element 13 is disposed on the heating surface 1133, the loading structure 113 can also serve as a heat insulation function, thereby further reducing heat loss, improving the thermal efficiency of the heating element 13, reducing the energy consumption of the aerosol generating device 1000, and extending the operating time of the aerosol generating device 1000. It is understood that the structure and function of the first dense structure 115 and the second dense structure 117 in this embodiment are basically the same as those in Embodiment 3. Please refer to the above description for details, which will not be repeated here.
[0137] It is understood that the heating element 10 in Embodiments 3, 4 and 5 may not have the second dense structure 117. That is, the heating element 10 in Embodiments 3, 4 and 5 only includes the porous structure 111, the loading structure 113 and the first dense structure 115.
[0138] Implementation Method Six
[0139] Please see Figure 12 and Figure 13 In this embodiment, the heating element 10 has a flat plate structure and includes a porous structure 111, a loading structure 113, and a storage element 19. The porous structure 111 and the storage element 19 are disposed on opposite sides of the loading structure 113, and the heating element 13 is disposed between the loading structure 113 and the storage element 19. The loading structure 113 is a dense structure. In this embodiment, the aerosol generating matrix stored in the storage element 19 can be a liquid matrix or a paste matrix.
[0140] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 (As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.
[0141] Implementation Method Seven
[0142] Please see Figure 14 and Figure 15 In this embodiment, the heating element 10 has a flat plate structure and includes a porous structure 111 and a loading structure 113. The heating element 13 is disposed between the loading structure 113 and the porous structure 111 (i.e., the heating element 13 is disposed on the connecting surface 1131). The loading structure 113 is a dense structure.
[0143] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 (As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.
[0144] Implementation Method Eight
[0145] Please see Figure 16 and Figure 17 In this embodiment, the heating element 10 has a flat plate structure and includes a porous structure 111 and a loading structure 113. The heating element 13 is disposed on the side of the loading structure 113 opposite to the porous structure 111 (i.e., the heating element 13 is disposed on the heating surface 1133). The loading structure 113 is a dense structure. In this embodiment, the heating element 10 can heat and atomize a solid substrate or a paste-like substrate.
[0146] Using the technical solution in this embodiment, the heat generated by the heating element 13 is blocked by the porous structure 111 and is difficult to dissipate to the outside, reducing heat dissipation. This allows the heat generated by the heating element 13 to act more on the aerosol generating matrix, thereby improving the thermal efficiency of the heating element 13 and reducing the aerosol generating device 1000 ( Figure 1 (As shown) reduce energy consumption and extend the operating time of the aerosol generator 1000.
