[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0025] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] In the description of this application, unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] As described in the background section, an aerosol generating device refers to a device or apparatus that converts a liquid, solid, or mixture thereof into an aerosol state through specific technical means. In related technologies, an aerosol generating device includes a heating element, which comprises a heating component and an external connector. The external connector is a welding wire capable of connecting to external components, and it is connected to the heating component by welding. However, the welding operation is cumbersome and complex, leading to increased production costs for the heating element.

[0030] Reference Figures 1 to 5 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a heating assembly, which includes a heating element 100, a mounting element 200, and an external connector 300. The heating element 100 is used to heat an aerosol matrix and has an external connector 110. The external connector 300 is disposed on the mounting element 200 and is electrically connected to the external connector 110 through contact with it. The external connector 300 is used to electrically connect to external components.

[0031] In this embodiment, the heating element is used in an aerosol generating device, the external connection structure 110 is an external electrode; the mounting component 200 is stationary relative to the heating element 100; the external connection component 300 is a conductive component and is stationary relative to the mounting component 200. Figure 1 The dashed lines in the image represent the obscured outline. Figures 3 to 5 These are schematic diagrams of the structure of the heating element after it has been rotated sequentially along the same direction, viewed from different angles.

[0032] The external connector 300 in this application achieves electrical connection with the heating element 100 through contact with the external connection structure 110, rather than through welding. This contact-based connection eliminates the welding step, reducing production processes, saving time and costs associated with welding, and improving the production efficiency and sealing effect of the heating element. It also avoids the procurement costs of welding wires and the instability in process and resistance caused by welding, eliminating installation stress on the welding wires and internal stress caused by the deformation of the heating element 100. This fundamentally avoids the risk of loosening or breakage of the solder joints during long-term use, significantly improving the connection reliability and service life of the heating element.

[0033] Reference Figures 1 to 5 In one embodiment, the mounting member 200 is sleeved on the outer periphery of the heating member 100 and is provided with a mounting hole 210, and the external connector 300 is embedded in the mounting hole 210.

[0034] In this embodiment, the heating element 100 is cylindrical, and the mounting element 200 is also cylindrical. The two end faces of the mounting element 200 correspond to and are coplanar with the two end faces of the heating element 100, and the entire structure of the heating element 100 is located inside the mounting element 200. Furthermore, a predetermined gap exists between the outer surface of the heating element 100 and the inner wall surface of the mounting element 200. A mounting hole 210 is provided on the outer surface of the mounting element 200 and is a through hole penetrating the mounting element 200 radially. The external connector 300 is completely embedded in the mounting hole 210. It is understood that the external connector 300 can also be fixedly mounted on the surface of the mounting element 200.

[0035] On the one hand, the mounting component 200 is fitted around the heating element 100, which not only wraps around the heating element 100 and plays a protective role, but also provides physical support for the heating element 100 and plays a fixing role, preventing the heating element 100 from shaking or shifting during use.

[0036] On the other hand, the external connector 300 is embedded in the mounting hole 210 of the mounting member 200, and the mounting member 200 realizes the installation and support of the external connector 300; at the same time, the mounting hole 210 provides precise positioning for the external connector 300, ensuring accurate and stable contact between the external connector 300 and the external connection structure 110 of the heating element 100.

[0037] On the other hand, the installation method of nesting and embedding is simple to operate, shortens the assembly time, and reduces the assembly difficulty; at the same time, the nesting and embedding structure makes the components in the heating element fit together tightly, effectively reducing the overall volume of the heating element.

[0038] Reference Figures 1 to 5 In one embodiment, the mounting component 200 is a PEEK component. In this embodiment, PEEK stands for Polyetheretherketone. It is understood that the mounting component 200 can also be an insulating component made of other materials, such as ceramic, mica, or polyimide.

[0039] PEEK has excellent insulation properties, effectively isolating the electrical connection between the heating element 100 and the external connector 300, ensuring electrical safety. At the same time, PEEK also has excellent high-temperature resistance, maintaining the structural integrity of the heating element 100 even when it is operating at high temperatures.

[0040] Furthermore, PEEK possesses high strength, high rigidity, and fatigue resistance. As a mounting component 200, it provides reliable physical support for the heating element 100, effectively preventing the heating element 100 from shaking or shifting during use, thus ensuring the stability and reliability of the heating assembly. In addition, PEEK exhibits excellent resistance to most acids, alkalis, organic solvents, and other chemicals, effectively preventing performance degradation or structural damage to the mounting component 200 due to chemical corrosion from the aerosol matrix.

[0041] Reference Figure 1 In one embodiment, the external connector 300 is a ejector pin. In this embodiment, the external connector 300 can be circular, square, or other shapes, and the material of the external connector 300 can be copper, copper-plated high-carbon steel, or silver-plated high-carbon steel.

[0042] On the one hand, the ejector pin has good conductivity, which can provide a stable and low-resistance current transmission path, ensuring a reliable electrical connection between the heating element 100 and external components (such as external power supply or control circuit), and reducing faults such as overheating and open circuit caused by poor contact.

[0043] On the other hand, the ejector pin has a defined geometric shape and size, and during the connection process, it can achieve precise matching with the corresponding mounting hole 210 and external connection structure 110, thereby achieving precise automatic docking.

[0044] On the other hand, the ejector pin structure is compact and occupies little space, which is conducive to the miniaturization and integration of the heating element. At the same time, the ejector pin also has good durability, extending the service life of the heating element and reducing its maintenance costs.

[0045] Reference Figures 3 to 5 In one embodiment, the heating element 100 includes a mounting structure 120 and a heating structure 130. The heating structure 130 is disposed in the mounting structure 120, and the external connection structure 110 is disposed in the mounting structure 120 and electrically connected to the heating structure 130.

[0046] In this embodiment, the mounting structure 120 is made of ceramic, quartz, polyimide, or polyphenylene sulfide, and is cylindrical in shape. It is understood that the mounting structure 120 may also be made of metal. The heating structure 130 and the external connection structure 110 are fabricated on the mounting structure 120 using thick-film printing technology. It is understood that the heating structure 130 and the external connection structure 110 may also be fabricated on the mounting structure 120 using other manufacturing methods, such as thin-film deposition, winding, embedding, welding, riveting, pressing, or bonding. At least a portion of the heating structure 130 protrudes from the outer peripheral surface of the mounting structure 120, and at least a portion of the external connection structure 110 protrudes from the outer peripheral surface of the mounting structure 120. The surface of the heating structure 130 away from the mounting structure 120 is a first surface, and the surface of the external connection structure 110 away from the mounting structure 120 is a second surface, located on the side of the first surface away from the mounting structure 120.

[0047] On the one hand, both the heating structure 130 and the external connection structure 110 are set on the mounting structure 120, which avoids the heating structure 130 and the external connection structure 110 from being connected by reassembly, simplifies the assembly process, reduces manufacturing difficulty and cost, and improves production efficiency.

[0048] On the other hand, the external connection structure 110 is directly installed in the mounting structure 120 and electrically connected to the heating structure 130, which shortens the current transmission path, reduces contact resistance and signal loss, and ensures that the heating structure 130 can stably obtain power, thereby achieving efficient heating.

[0049] On the other hand, the mounting structure 120, the heating structure 130, and the external connection structure 110 can be made of appropriate materials according to actual needs, so that the heating element 100 can have multiple properties at the same time.

[0050] Reference Figures 3 to 5 In one embodiment, there are multiple heating structures 130, which are arranged at intervals.

[0051] Multiple spaced heating structures 130 generate heat from different areas, preventing heat concentration in one spot and effectively improving heating uniformity. Furthermore, some heating structures 130 can be selectively activated or deactivated according to actual usage needs, achieving graded control of heating power and temperature. In addition, if one heating structure 130 fails, the others can continue to operate, maintaining a certain level of heating function, preventing the entire heating element 100 from failing completely, thus ensuring the reliability and stability of the heating element 100.

[0052] Reference Figures 3 to 5In one embodiment, there are two heating structures 130 and three external connecting structures 110 and external connectors 300. The two ends of the two heating structures 130 that are close to each other are electrically connected to the same external connecting structure 110, and the two ends of the two heating structures 130 that are far apart from each other are electrically connected to two other external connecting structures 110 respectively. The three external connectors 300 are in contact with the three external connecting structures 110 respectively.

[0053] In this embodiment, when the two heating structures 130 are used in parallel, all three external connectors 300 are energized.

[0054] When two heating structures 130 are used in series, two of the three external connectors 300 that are in contact with the ends of the two heating structures 130 that are far apart from each other are in an energized state, while the other external connector 300 is in an unenergized state.

[0055] When one of the two heating structures 130 is in use and the other heating structure 130 is not in use, one of the two external connectors 300 that are in contact with the two ends of the two heating structures 130 that are far apart from each other is in an energized state, the other is in an unenergized state, and the remaining external connector 300 is in an energized state.

[0056] It is understood that the number of heating structures 130 can also be three, four or more, and two adjacent heating structures 130 are electrically connected through the same external connection structure 110.

[0057] By controlling the three external connectors 300 to achieve power on and off, the two heating structures 130 can be connected in parallel (in this case, the total resistance decreases and the current increases, which can achieve high power rapid heating, and is usually suitable for the start-up stage), in series (in this case, the total resistance increases and the current decreases, which can achieve low power constant temperature maintenance, and is suitable for the heat preservation stage), or in a single heating structure 130 operation mode (this mode can keep the heating element 100 operating at the minimum operating temperature and reduce the risk of complete failure of the heating element 100).

[0058] Meanwhile, compared to the design where each heating structure 130 is independently configured with two external connection structures 110, the above structural design reduces one connection point and lowers production costs by sharing the middle external connection structure 110.

[0059] Reference Figures 3 to 5 In one embodiment, the heating element 100 further includes a conductive structure 140, and the number of conductive structures 140 is two; the two conductive structures 140 are electrically connected to the two ends of the two heating structures 130 that are close to each other, and are electrically connected to the same external connection structure 110.

[0060] In this embodiment, the conductive structure 140 is a low-resistance structure, and the material of the conductive structure 140 is copper, nickel, gold, or silver. Simultaneously, the conductive structure 140 is also fabricated on the mounting structure 120 using thick-film printing technology. Furthermore, at least a portion of the conductive structure 140 protrudes from the outer peripheral surface of the mounting structure 120, and the surface of the conductive structure 140 furthest from the mounting structure 120 is a third surface, located between the first and second surfaces.

[0061] On the one hand, the conductive structure 140 is electrically connected to the two ends of the two heating structures 130 that are close to each other, and is also electrically connected to the same external connection structure 110. This design increases the number of electrical connection points, making the current transmission more stable and reliable. Compared with directly connecting the heating structure 130 to the external connection structure 110, the conductive structure 140 can share the current, reduce the current load of a single connection point, reduce the risk of overheating, oxidation or even damage to the connection point due to excessive current, and effectively extend the service life of the heating element 100.

[0062] On the other hand, since the two heating structures 130 form a relatively closed loop after being connected by the conductive structure 140, the current flows more orderly in this loop, reducing the interference of the electromagnetic field generated by the current on the outside world. At the same time, the conductive structure 140 can also block the influence of external electromagnetic interference on the heating structure 130 to a certain extent, improving the stability and reliability of the heating element 100.

[0063] Reference Figures 3 to 5 In one embodiment, the heating structure 130 is distributed along a curve. In this embodiment, the heating structure 130 is distributed in a meandering manner. It is understood that the heating structure 130 may also be distributed along a straight line.

[0064] The curved distribution arrangement not only allows the heating structure 130 to better fit and adapt to the shape of the mounting structure 120, but also allows the heat generated by the heating structure 130 to be distributed more evenly.

[0065] Reference Figures 3 to 5 In one embodiment, the outer surface of the mounting structure 120 is provided with a through hole 121, which extends into the interior of the mounting structure 120.

[0066] In this embodiment, there are multiple through holes 121. A portion of the through holes 121 extend along the axial direction of the mounting structure 120, and a portion extend along the circumferential direction of the mounting structure 120. It can be understood that the length direction of the through holes 121 may also extend in a direction intersecting with the axial or circumferential direction of the mounting structure 120.

[0067] The through-hole 121 not only allows for more efficient heat exchange between the inside and outside of the mounting structure 120, helping to balance the temperature and ensure more uniform heating of the aerosol matrix, avoiding localized overheating or underheating, but also reduces weight and saves materials. Furthermore, it provides a channel for gas flow within and outside the mounting structure 120.

[0068] Reference Figures 1 to 5 According to another aspect of this application, embodiments of this application also provide an aerosol generating device, which includes a power supply component and the aforementioned heating component. The power supply component includes a power supply element 400 and a control element 500, with the power supply element 400 electrically connected to the control element 500 and the control element 500 electrically connected to an external connector 300.

[0069] In this embodiment, the aerosol generating device is a heated non-combustible appliance. It is understood that the aerosol generating device can also be an atomizing device. The power supply unit 400 is a power battery, and the control unit 500 is a control circuit board.

[0070] The control unit 500 can precisely adjust the output current, voltage, or power supply time according to different working modes, heating requirements, and specific requirements for aerosol generation, thereby achieving precise control over the heating temperature and duration of the heating component. This helps ensure that the heating component can heat the aerosol matrix at the most suitable temperature, avoiding problems such as aerosol quality degradation and the generation of harmful substances due to excessively high temperatures, as well as insufficient heating and low aerosol generation due to excessively low temperatures. This improves the quality and stability of aerosol generation and provides users with a better user experience.

[0071] In summary, implementing the heating element and aerosol generating device provided in this embodiment has at least the following beneficial technical effects: The external connector 300 in this application achieves electrical connection with the heating element 100 through contact with the external connection structure 110, rather than through welding. This contact-type connection eliminates the welding step, reducing production processes, saving time and costs associated with welding, and improving the production efficiency and sealing effect of the heating element. It also avoids the procurement costs of welding wires and the instability in process and resistance caused by welding, eliminating the installation stress of the welding wires and the internal stress generated by the working deformation of the heating element 100. This fundamentally avoids the risk of loosening or breakage of the solder joints during long-term use, significantly improving the connection reliability and service life of the heating element.

[0072] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
