Technical Field
[0001] This application belongs to the field of atomization technology, and more specifically, relates to a heating layer preform, a heating element semi-finished product, a heating element, and an aerosol generating device. Background Technology
[0002] The aerosol generating device can use a heating element to heat the aerosol generating matrix, thereby atomizing the aerosol generating matrix.
[0003] In related technologies, heating elements mainly utilize thick film technology to form heating circuits (heating layers) on the heating element substrate. However, the complexity of thick film technology increases the processing difficulty of heating elements. Utility Model Content
[0004] The purpose of this application is to provide a heating layer preform, a heating element semi-finished product, a heating element, and an aerosol generating device to reduce the processing difficulty of the heating element.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, this application provides a heating layer preform, which includes a heating layer body and a support member. The heating layer body includes a conductive member and a plurality of heating members, which are arranged sequentially at intervals. The conductive member is electrically connected to two adjacent heating members. The heating layer body is used to generate heat after being energized. The spacing direction of the plurality of heating members intersects the thickness direction of the heating layer body. The support member is disconnectably connected to two adjacent heating members.
[0007] Through the above technical solution, the prefabricated component is electrically connected to two adjacent heating components via conductive parts. This allows multiple heating components of the heating layer body to be energized, facilitating heating. Furthermore, the support component can be disengaged from the two adjacent heating components, providing support for the multiple heating components of the heating layer body. This helps prevent deformation of the heating layer body, improves its stability, and facilitates welding of the heating layer body to the substrate of the heating element, thereby enabling the manufacture of the heating element. Moreover, welding the heating layer body to the substrate of the heating element can replace the thick-film process for heating element fabrication, reducing processing difficulty and thus lowering costs.
[0008] Therefore, the heating layer preform provided in this application can be used to manufacture heating elements, which can reduce the processing difficulty of heating elements and help reduce costs.
[0009] In some embodiments, along the spacing direction of the plurality of heating elements, a support element is located between two adjacent heating elements, and / or a conductive element is located between two adjacent heating elements.
[0010] In this way, the prefabricated heating layer provided in this application can help avoid the overlap between the supporting component and the heating component, thereby facilitating the co-layer arrangement of the supporting component and the heating component, and further facilitating the welding of the prefabricated component to the substrate of the heating element. Furthermore, the prefabricated heating layer provided in this application can help avoid the overlap between the conductive component and the heating component, thereby facilitating the co-layer arrangement of the conductive component and the heating component, and further facilitating the welding of the prefabricated component to the substrate of the heating element.
[0011] In some embodiments, the heating component includes a first connecting surface for connecting to a substrate, the conductive component includes a second connecting surface for connecting to a substrate, and the supporting component includes a third connecting surface for connecting to a substrate; wherein the first connecting surface is aligned with the second connecting surface, and / or the first connecting surface is aligned with the third connecting surface.
[0012] In this way, the heating layer preform provided in this application aligns the first connecting surface with the second connecting surface, allowing the heating component and the conductive component to be connected to the substrate separately. This helps to avoid gaps between the preform and the substrate and facilitates welding between the preform and the substrate. Furthermore, the heating layer preform provided in this application aligns the first connecting surface with the third connecting surface, allowing the heating component and the supporting component to be connected to the substrate separately. This helps to avoid gaps between the preform and the substrate and facilitates welding between the preform and the substrate. When the first connecting surface is aligned with the second connecting surface, and also with the third connecting surface, the second connecting surface is also aligned with the third connecting surface. This allows the conductive component and the supporting component to be connected to the substrate separately, helping to avoid gaps between the preform and the substrate and facilitating welding between the preform and the substrate.
[0013] In some embodiments, the support member includes a plurality of spaced-apart support portions, the spacing direction of the plurality of heating members intersects the spacing direction of the plurality of support portions, and the spacing direction of the plurality of support portions intersects the thickness direction of the heating layer body.
[0014] In this way, the support components can support the heating components at multiple locations through the support parts, which can improve the stability of the heating layer body.
[0015] In some embodiments, the spacing direction of the plurality of heating elements is a first linear direction, the thickness direction of the heating layer body is a second linear direction, and the spacing direction of the plurality of support portions is a third linear direction.
[0016] In this way, the preform provided in this application can be a sheet structure, and the preform can be welded to the surface of the sheet structure substrate.
[0017] Optionally, the first straight line direction is perpendicular to both the second and third straight line directions, and the second straight line direction is perpendicular to the third straight line direction. This results in a prefabricated component with a regular shape, facilitating processing.
[0018] In some embodiments, a preform is formed to enclose a cavity with a first axis, and multiple heating components are arranged sequentially and spaced apart around the first axis. The preform includes multiple supporting components, which are also arranged sequentially and spaced apart around the first axis. In this way, the preform can be used for heating elements; that is, the heating element can be a heating tube, and the substrate of the heating element can be a cylindrical structure.
[0019] In some embodiments, the cavity is a cylindrical cavity, or the cavity is a prismatic cavity. In this way, the shape of the preform can be specifically designed according to the shape of the heating element, which has good applicability.
[0020] Secondly, this application provides a semi-finished heating element, which includes a substrate and a preform of any of the above embodiments, wherein the preform is welded to the substrate. The semi-finished heating element provided by this application has the same or similar technical effects as the preform of any of the above embodiments, and will not be described in detail here.
[0021] Thirdly, this application provides a heating element, which includes a heating layer body and a substrate. The heating layer body includes a conductive component and a plurality of heating components, which are arranged sequentially at intervals. The conductive component is electrically connected to two adjacent heating components. The heating layer body is used to generate heat after being energized. The spacing direction of the plurality of heating components intersects the thickness direction of the heating layer body. There is a gap between two adjacent heating components. The heating layer body is welded to the surface of the substrate.
[0022] Through the above technical solution, the heating element is electrically connected to two adjacent heating elements via conductive components. This allows multiple heating elements of the heating layer body to be energized, facilitating heating. Furthermore, the presence of a gap between adjacent heating elements reduces the connection area between them, improving the uniformity of heating the substrate by the heating layer body, thus ensuring uniform heating of the heating element. In addition, welding the heating layer body to the substrate of the heating element can replace thick-film processes in heating element fabrication, reducing processing difficulty and consequently lowering costs.
[0023] Therefore, the heating element provided in this application can reduce processing difficulty and help reduce manufacturing costs.
[0024] In some embodiments, the heating layer body includes a first electrical contact and a second electrical contact, the first electrical contact being used to connect to the positive terminal of a power source and the second electrical contact being used to connect to the negative terminal of a power source, the first electrical contact and the second electrical contact being located on different heating components; and / or, the substrate is a sheet structure, and the heating layer body is welded to at least one surface of the substrate; and / or, the substrate is a cylindrical structure, and the heating layer body is welded to the outer peripheral wall of the substrate.
[0025] In this way, the first and second electrical contacts are located on different heating components, allowing the heating layer body to be energized and enabling all heating components to generate heat, thus improving the uniformity of heating. Optionally, the substrate can be a sheet structure, and the heating element provided in this application can be a sheet heating element. Optionally, the substrate can also be a cylindrical structure, and the heating element provided in this application can be a tubular heating element (heating tube).

[0051] Please see Figure 1 This application provides an aerosol generating device 1000, which can atomize an aerosol generating matrix by heating it with a heating element 300. Optionally, the heating element 300 can be a cylindrical structure. Exemplarily, the heating element 300 can be a cylindrical structure. Exemplarily, the heating element 300 can be a square cylindrical structure.
[0052] The aerosol generating device 1000 provided in this application also includes a power supply 100 and a lead wire 200 connected to the power supply 100. The lead wire 200 is connected to a heating element 300, so that the power supply 100 can supply power to the heating element 300, so that the heating element 300 can be powered and heated, thereby heating the aerosol generating matrix and causing the aerosol generating matrix to atomize.
[0053] Please see Figure 2 Optionally, the heating element 300 can be a sheet-like structure.
[0054] In related technologies, the heating element 300 mainly utilizes a thick film process to form heating circuits (heating layers) on the heating element 300 substrate 10. The thick film process can include screen printing, printing, and spraying. However, the complexity of the thick film process increases the processing difficulty of the heating element 300.
[0055] To resolve the above technical issues, please refer to the following: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The heating element 300 provided in this embodiment includes a substrate 10, which has thermal conductivity and insulation properties. Optionally, the substrate 10 can be made of a ceramic or glass-like insulating and high-temperature resistant material. Optionally, the substrate 10 can be made of metal, and the metal substrate 10 achieves insulation using an insulation process. For example, an insulating and high-temperature resistant film layer can be formed on the surface of the substrate 10.
[0056] The heating element 300 provided in this embodiment further includes a heating layer body 20, which is used to generate heat after being energized. The heating layer body 20 includes a conductive component 22 and a plurality of heating components 21, which are arranged sequentially at intervals, with the spacing direction of the plurality of heating components 21 intersecting the thickness direction of the heating layer body 20. This allows the plurality of heating components 21 to be arranged side by side and at intervals, thereby improving the uniformity of heating of the heating element 300.
[0057] For example, the spacing direction of the plurality of heating elements 21 is perpendicular to the thickness direction of the heating layer body 20.
[0058] Optionally, the conductive component 22 is electrically connected to two adjacent heating components 21, so that multiple heating components 21 of the heating layer body 20 can be energized, which facilitates the heating layer body 20 to heat the substrate 10, thereby allowing the substrate 10 to transfer heat to the aerosol matrix 400.
[0059] Optionally, there is a gap 204 between two adjacent heating elements 21, which can reduce the connection area between the two adjacent heating elements 21, which is beneficial to improve the uniformity of heating of the substrate 10 by the heating layer body 20, thereby facilitating uniform heating of the heating element 300.
[0060] Optionally, the heating layer body 20 is welded to the surface of the substrate 10. In this way, the heating layer body 20 is welded to the substrate 10 of the heating element 300, which can replace the thick film process to prepare the heating element 300. This helps to reduce the processing difficulty of the heating element 300, and thus helps to reduce the cost of the heating element 300.
[0061] Therefore, the heating element 300 provided in this application embodiment can reduce processing difficulty and help reduce manufacturing costs.
[0062] Optionally, the heating element 21 can be serpentine. Optionally, the heating element 21 can be S-shaped. Optionally, the heating element 21 can be U-shaped. Optionally, the heating element 21 can be spiral-shaped. It is understood that the shape of the heating element 21 can be customized according to the specific product requirements.
[0063] Please continue reading. Figure 2The substrate 10 can be a sheet structure, and the heating layer body 20 is welded to at least one side surface of the substrate 10. When the substrate 10 is a sheet structure, the heating element 300 can also be a sheet structure.
[0064] Please refer to the following: Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The substrate 10 can be a cylindrical structure, and the heating layer body 20 is welded to the outer peripheral wall of the substrate 10. When the substrate 10 is a cylindrical structure, the heating element 300 can also be a cylindrical structure, that is, the heating element 300 can be a tubular heating element 300 (heating tube).
[0065] It is understandable that the shapes of the substrate 10 and the heating element 300 can be specifically set according to the type of aerosol generating device 1000.
[0066] In some embodiments, please continue reading Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The heating layer body 20 includes a first electrical contact 201 and a second electrical contact 202. The first electrical contact 201 is used to connect to the positive terminal of the power supply 100, and the second electrical contact 202 is used to connect to the negative terminal of the power supply 100. The first electrical contact 201 and the second electrical contact 202 are located on different heating components 21. In this way, the first electrical contact 201 and the second electrical contact 202 are located on different heating components 21, which allows the heating layer body 20 to be energized, and allows the different heating components 21 to be connected into a continuous heating circuit, which facilitates the improvement of heating uniformity.
[0067] Optionally, the heating layer body 20 may also include a third electrical contact 203, which can be connected to a control circuit.
[0068] Optionally, the third contact 203 may be located between the first contact 201 and the second contact 202.
[0069] Optionally, the heating layer body 20 includes two heating components 21, one of which is a first heating component 21a, and the other is a second heating component 21b. The first heating component 21a includes a first end 21a1 and a second end 21a2, and a first electrical contact 201 may be disposed at the first end 21a1. The second heating component 21b includes a third end 21b1 and a fourth end 21b2, and a second electrical contact 202 may be disposed at the fourth end 21b2. A conductive component 22 may connect the second end 21a2 and the third end 21b1, thereby making the first heating component 21a and the second heating component 21b conductive.
[0070] Optionally, the third electrical contact 203 may be located at the second end 21a2.
[0071] Optionally, the third electrical contact 203 may be located at the third end 21b1.
[0072] Optionally, the third electrical contact 203 may be disposed on the conductive component 22.
[0073] It should be noted that when the heating element 300 has a cylindrical structure, at least two adjacent heating elements 21 need to be isolated from each other, that is, there needs to be an insulating gap 205 between at least two adjacent heating elements 21. This allows the heating layer body 20 to form a longer conductive path, which facilitates uniform heating of the heating element 300.
[0074] The first contact 201 and the second contact 202 are located on different sides of the insulation gap 205 and are positioned close to the insulation gap 205.
[0075] For example, when the heating layer body 20 includes two heating elements 21, there is an insulating gap 205 between the first end 21a1 of the first heating element 21a and the fourth end 21b2 of the second heating element 21b, that is, the first end 21a1 of the first heating element 21a and the fourth end 21b2 of the second heating element 21b are insulated. There is a disconnecting gap 204 between the second end 21a2 of the first heating element 21a and the third end 21b1 of the second heating element 21b, and the conductive element 22 can connect the second end 21a2 and the third end 21b1. That is, the second end 21a2 of the first heating element 21a and the third end 21b1 of the second heating element 21b are electrically connected, but there is a disconnecting gap 204. This can facilitate uniform heating of the heating element 300.
[0076] The inventors discovered that the heating layer body 20 is thin, and the heating layer body 20 is prone to deformation after it is manufactured and during the process of welding the heating layer body 20 to the substrate 10.
[0077] To address the issue of easy deformation of the heating layer body 20, please refer to the following: Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 This application provides a heating layer preform 311, which includes a heating layer body 20. The heating layer body 20 includes a conductive component 22 and a plurality of heating components 21. The plurality of heating components 21 are arranged sequentially at intervals, and the spacing direction of the plurality of heating components 21 intersects the thickness direction of the heating layer body 20. This allows the plurality of heating components 21 to be arranged side by side and at intervals, thereby improving the heating uniformity of the heating element 300.
[0078] For example, the spacing direction of the plurality of heating elements 21 is perpendicular to the thickness direction of the heating layer body 20.
[0079] Optionally, the conductive component 22 is electrically connected to two adjacent heating components 21, and the heating layer body 20 is used to generate heat after being energized. This allows the multiple heating components 21 of the heating layer body 20 to be energized, facilitating the heating layer body 20 to heat the substrate 10, thereby enabling the substrate 10 to transfer heat to the aerosol matrix 400.
[0080] The heating layer preform 311 provided in this application embodiment also includes a support member 30. The support member 30 can be disconnected from two adjacent heating members 21. The support member 30 can support multiple heating members 21 of the heating layer body 20, which helps to avoid deformation of the heating layer body 20, improves the stability of the heating layer body 20, and facilitates welding of the heating layer body 20 to the substrate 10 of the heating element 300, thereby enabling the manufacturing of the heating element 300.
[0081] Furthermore, when the heating layer body 20 is welded to the substrate 10 of the heating element 300, the heating element 300 can be prepared instead of the thick film process, which helps to reduce the processing difficulty and thus reduce the cost.
[0082] Therefore, the heating layer preform 311 provided in this application embodiment can be used to manufacture the heating element 300, which can help avoid deformation of the heating layer body 20, reduce the processing difficulty of the heating element 300, and help reduce costs.
[0083] It is understood that the support member 30 can be disconnected from two adjacent heating members 21. When the support member 30 is disconnected, a gap 204 can be formed between the two adjacent heating members 21. This reduces the connection area between the two adjacent heating members 21, which helps to improve the uniformity of heating of the substrate 10 by the heating layer body 20, thereby helping the heating element 300 to heat up uniformly.
[0084] In some embodiments, the support member 30 is located between two adjacent heating members 21 along the spacing direction of the plurality of heating members 21. In this way, the heating layer preform 311 provided in this application embodiment can help avoid the overlap of the support member 30 and the heating member 21, thereby facilitating the co-layer arrangement of the support member 30 and the heating member 21, and further facilitating the welding of the preform 311 to the substrate 10 of the heating element 300.
[0085] Optionally, the conductive component 22 is located between two adjacent heating components 21. In this way, the heating layer preform 311 provided in this application can help avoid the overlap of the conductive component 22 and the heating component 21, thereby facilitating the co-layer arrangement of the conductive component 22 and the heating component 21, and further facilitating the welding of the preform 311 to the substrate 10 of the heating element 300.
[0086] In some embodiments, the heating component 21 includes a first connecting surface for connecting the substrate 10, the conductive component 22 includes a second connecting surface for connecting the substrate 10, and the support component 30 includes a third connecting surface for connecting the substrate 10; wherein the first connecting surface is aligned with the second connecting surface, and / or the first connecting surface is aligned with the third connecting surface.
[0087] When the first connecting surface and the second connecting surface are aligned, the heating component 21 and the conductive component 22 can be connected to the substrate 10 respectively, which helps to avoid gaps between the preform 311 and the substrate 10 and facilitates welding of the preform 311 and the substrate 10.
[0088] Furthermore, when the first connecting surface and the third connecting surface are aligned, the heating component 21 and the supporting component 30 can be connected to the substrate 10 respectively, which helps to avoid gaps between the preform 311 and the substrate 10 and facilitates welding of the preform 311 and the substrate 10.
[0089] It is understandable that when the first connecting surface is aligned with the second connecting surface and the third connecting surface, the second connecting surface is also aligned with the third connecting surface. In this way, the conductive component 22 and the supporting component 30 can be connected to the substrate 10 respectively, which helps to avoid gaps between the preform 311 and the substrate 10 and facilitates welding of the preform 311 and the substrate 10.
[0090] In some embodiments, the support member 30 includes a plurality of spaced support portions 31, the spacing direction of the plurality of heating members 21 intersects the spacing direction of the plurality of support portions 31, and the spacing direction of the plurality of support portions 31 intersects the thickness direction of the heating layer body 20.
[0091] For example, the spacing direction of the plurality of heating elements 21 is perpendicular to the spacing direction of the plurality of support portions 31, and the spacing direction of the plurality of support portions 31 is perpendicular to the thickness direction of the heating layer body 20.
[0092] In this way, the support member 30 can support the heating member 21 at multiple positions through the support part 31, which can improve the stability of the heating layer body 20.
[0093] Please continue reading. Figure 11 In some embodiments, the spacing direction of the plurality of heating elements 21 is a first straight line direction, the thickness direction of the heating layer body 20 is a second straight line direction, and the spacing direction of the plurality of support portions 31 is a third straight line direction.
[0094] In this way, the preform 311 provided in this application embodiment can be a sheet structure, and the preform 311 can be welded to the surface of the sheet structure substrate 10.
[0095] Optionally, the first straight line direction is perpendicular to both the second and third straight line directions, and the second straight line direction is perpendicular to the third straight line direction. This gives the preform 311 a regular shape, facilitating processing.
[0096] Please continue reading. Figure 12 , Figure 13 , Figure 14 and Figure 15 In some embodiments, the preform 311 encloses a cavity with a first axis, and multiple heating components 21 are arranged sequentially and spaced apart around the first axis. The preform 311 includes multiple supporting components 30, which are arranged sequentially and spaced apart around the first axis. In this way, the preform 311 can be used for a cylindrical heating element 300 (heating tube), that is, the heating element 300 can be a heating tube, and the substrate 10 of the heating element 300 can be a cylindrical structure.
[0097] It is understandable that, when the heating element 300 has a cylindrical structure, the spacing direction of the multiple heating elements 21 can change depending on the position of the heating elements 21, and the spacing direction of the multiple heating elements 21 is always perpendicular to the axial direction of the first axis. The thickness direction of the heating layer body 20 can also change depending on the position of the heating elements 21, and the thickness direction of the heating layer body 20 is always perpendicular to the axial direction of the first axis. The spacing direction of the multiple support portions 31 is the axial direction of the first axis.
