[0018] The heating element structure is an integral part of the aerosol generation device. During the use of the aerosol generation device, the performance of the heating element structure directly affects the heating effect of the aerosol rod and the user experience.

[0019] In existing technologies, the internal structure of the heating element is sealed with a traditional sealing gasket, which is prone to poor sealing. This can lead to heat loss or leakage of aerosol oil when the aerosol rod is heated, affecting the user experience.

[0020] In view of this, the present invention provides a heating element structure, which aims to improve the sealing performance inside the heating element structure.

[0021] Please see Figure 1 and Figure 2 The heating element structure includes a shell 1, a tube 2, and a heating element 3. The shell 1 has an internal cavity with a first opening 11, which can accommodate the tube 2 and the heating element 3, forming a complete heating system. The tube 2 is disposed within the cavity of the shell 1, and a mounting cavity 4 is formed between the outer wall of the tube 2 and the inner wall of the shell 1. This mounting cavity 4 is used to accommodate the heating element 31 of the heating element 3, and can also be used to accommodate other components of the heating element 3, such as insulation cotton. The first end 21 of the tube 2 has an open first opening 211. The cross-sectional shape of the tube 2 and the specific shape of the first opening 211 are not specifically limited in this embodiment of the invention; they can be circular, elliptical, or other shapes suitable for inserting the aerosol rod. The first opening 211 communicates with the first opening 11 of the shell 1, allowing the aerosol rod to pass through the first opening 11 and the first opening 211 from the outside of the shell 1 and enter the interior of the tube 2. The heating element 31 of the heating component 3 can heat the aerosol rod inside the heating tube 2 by heating the tube 2.

[0022] The edge of the first port 211 is fused to the housing 1. "Fusing seal" can be understood as a sealing connection achieved through welding, which effectively avoids the sealing problems that may arise with traditional gaskets. This welding process not only makes the connection between the first port 211 and the housing 1 more secure but also prevents aerosol oil leakage. Furthermore, this "fusing seal" has excellent high-temperature resistance, maintaining a stable sealing effect even after prolonged use.

[0023] Furthermore, the edge of the first port 211 can be fused to the interior of the shell wall of the housing 1, or it can be fused to the surface of the shell wall of the housing 1, such as the inner wall surface of the first opening 11 of the housing 1. In other words, the edge of the first port 211 can be inserted into the shell wall of the housing 1 or not, depending on the actual production process and product design requirements.

[0024] As for the second pipe end 22 of the pipe body 2, that is, the pipe end opposite to the first pipe end 21 along the extension direction of the pipe body 2, this embodiment of the utility model does not make specific limitations. The second pipe end 22 can be similar to the first pipe end 21, and can be sealed and fused to the housing 1, or it can be detachably connected to the housing 1.

[0025] The overall structural principle of this heating element is as follows: During use, the aerosol rod is inserted through the first opening 11 of the housing 1 and enters the tube 2 through the first port 211. The heating element 31 of the heating assembly 3 is located in the mounting cavity 4. By heating the tube 2, heat is transferred to the aerosol rod inside the tube 2, thereby realizing the heating function of the aerosol rod. Since the edge of the first port 211 is connected to the housing 1 by a sealed fusion weld, leakage of aerosol oil from this point into the mounting cavity 4 is prevented.

[0026] The heating element structure provided by this utility model includes a shell 1, a tube 2, and a heating element 3. The shell 1 has an internal cavity with a first opening 11. The tube 2 is disposed within the cavity of the shell 1, and an mounting cavity 4 is formed between the outer wall of the tube 2 and the inner wall of the shell 1. The first end 21 of the tube 2 has an open first port 211. The first port 211 communicates with the first opening 11 for insertion of an aerosol rod. The heating element 31 of the heating element 3 is disposed within the mounting cavity 4 to heat the aerosol rod inside the tube 2. The edge of the first port 211 is sealed and fused to the shell 1. This utility model embodiment effectively improves the sealing performance of the heating element structure by sealing the edge of the first port 211 to the shell 1, avoiding the aerosol oil leakage problem caused by the formation of sealing gaskets in traditional methods. Simultaneously, this design enhances the overall stability of the structure, enabling it to maintain a reliable connection even under prolonged high-temperature operating conditions.

[0027] In some embodiments, please refer to Figure 2To improve the efficiency of heat transfer from the heating element 31 to the aerosol rod, and to reduce the heat transfer from the tube 2 to the outer wall of the shell 1, the tube 2 is made of metal and the shell 1 is made of plastic; that is, the tube 2 is a metal tube and the shell 1 is a plastic shell. Accordingly, to accommodate the metal tube 2 and the plastic shell 1, a special design was made for the sealing and welding method of the edge of the first tube 2 and the shell 1.

[0028] Specifically, the edge of the first port 211 can be connected to the shell 1 via a high-frequency welding process. During high-frequency welding, the edge of the first port 211 utilizes a high-frequency magnetic field to generate eddy currents, rapidly heating up through resistance to reach a high temperature. The heat generated by the edge of the first port 211 melts the plastic through heat conduction. The molten plastic fills the surface structure of the edge of the first port 211, and then cools and solidifies, thereby achieving a firm bond between the edge of the first port 211 and the shell 1, forming a stable mechanical connection.

[0029] Besides high-frequency welding, injection molding can also be used to achieve a sealed connection between the first port 211 and the shell 1. Specific injection molding methods include at least the following two: First, molten material is injected into the gap between the first port 211 and the shell 1, and after cooling and solidification, a tight connection structure is formed. This method is relatively simple to operate. Second, the tube 2 is first placed in an injection mold, and then injection molding is performed to form the shell 1, thereby achieving an integrated sealed connection between the tube 2 and the shell 1 during the molding process.

[0030] Whether high-frequency welding or injection molding is used, the first port 211 can be tightly and firmly connected to the shell 1, giving the connection high strength and durability. Even in high-temperature environments, its performance remains stable. Therefore, compared to traditional gasket connections, this method avoids sealing failures caused by aging or deformation of traditional gaskets, and also enhances the stability and durability of the heating element structure during use.

[0031] In some implementations, please refer to Figure 2 In order to facilitate the welding of the tube body 2 to the shell 1 and reduce the situation where the tube body 2 is difficult to contact the shell 1 due to radial error, thus making it difficult to weld the tube body 2 to the shell 1, the shape of the first tube end 21 of the tube body 2 has been specifically designed.

[0032] Specifically, in the first direction, the cross-sectional area of ​​the first pipe end 21 gradually increases as it moves further away from the second pipe end 22. Here, the first direction refers to the extension direction of the pipe body 2. Figure 2 The second pipe end 22 is represented by the dashed line a in the middle; the second pipe end 22 is the pipe end of the pipe body 2 that is opposite to the first pipe end 21 in the first direction.

[0033] As the cross-sectional area of ​​the first pipe end 21 gradually increases, this design allows the pipe body 2 to more easily contact and weld with the shell 1 near the first pipe opening 211. Especially during high-frequency welding or injection molding, the increased cross-section provides a larger contact area, thereby improving the strength and sealing of the weld. In addition, this design can effectively disperse stress concentration caused by thermal expansion and contraction, preventing cracks or loosening at the connection due to temperature changes.

[0034] In some embodiments, please refer to Figure 2 To facilitate user replacement or maintenance of the heating element 3, the bottom of the mounting cavity 4 is designed to be detachable. Specifically, the heating element structure also includes a base 5; the base 5 is detachably disposed at the end of the mounting cavity 4 near the second tube end 22 to seal the mounting cavity 4; the second tube end 22 is the tube end of the tube body 2 opposite to the first tube body 2 in a first direction.

[0035] Since the mounting cavity 4 is formed by the outer wall of the tube 2 and the inner wall of the shell 1, the statement "the base 5 is detachably disposed at the end of the mounting cavity 4 near the second tube end 22" can be understood as the base 5 being detachably connected between the second tube end 22 and the shell 1. By disassembling the base 5, the user can easily remove the heating element 3 from the mounting cavity 4 for cleaning or replacement without damaging the entire heating element structure.

[0036] This utility model embodiment uses the detachable design of the base 5 to form a non-detachable sealed connection at one end of the mounting cavity 4 corresponding to the first tube end 21, and a detachable sealed connection at one end corresponding to the second tube end 22. This ensures the sealing performance of the heating element structure on the one hand, and improves the convenience of maintenance and replacement of the heating component 3 on the other hand.

[0037] In some embodiments, please refer to Figure 2 Since the inside of the tube body 2 is used to house the aerosol rod for user inhalation, the second end 22 of the tube body 2 is designed to be open to ensure smooth airflow during user inhalation. However, considering the open design of the second end 22, in order to prevent the aerosol oil inside the tube body 2 from flowing into the mounting cavity 4 and to reduce the heat transfer from the second end 22 to other structures (such as the base 5 and the sealing gasket set between the base 5 and the second end 22), a sealing and heat insulation structure needs to be added between the second end 22 and the base 5.

[0038] Specifically, the second pipe end 22 is provided with an open second pipe port 221, and a heat insulation gasket 6 is fused to the edge of the second pipe port 221. The specific implementation process of fusing the heat insulation gasket 6 to the edge of the second pipe port 221 is as follows: first, the pipe body 2 is placed in the injection mold, and then injection molding is performed to form the heat insulation gasket 6, so that the heat insulation gasket 6 is tightly combined with the edge of the second pipe port 221.

[0039] This embodiment of the invention, through the provision of the heat insulation gasket 6, effectively isolates heat transfer, preventing the high temperature of the second tube end 22 from affecting the base 5 or other adjacent structures. Simultaneously, the heat insulation gasket 6 also possesses a certain sealing performance, preventing aerosol oil from leaking from the second tube opening 221 into the mounting cavity 4, thereby further enhancing the overall reliability of the heating element structure.

[0040] It should be noted that base 5 can be as follows: Figure 2 The second port 221 can be sealed or left unsealed. Even with the second port 221 sealed by the base 5, a through-hole is provided in the base 5 to ensure smooth airflow. This through-hole allows outside air to enter the base 5. Therefore, the specific airflow direction is as follows: outside air enters the base 5 through the through-hole, then passes through the second port 221 and enters the tube 2; finally, after passing through the aerosol rod inside the tube 2, the airflow carrying the aerosol mist flows out from the first port 211 and into the user's mouth. This airflow path design ensures a stable airflow supply for the user during suction.

[0041] In some embodiments, please refer to Figure 2 and Figure 3 To enhance heat insulation and sealing, the edge of the second pipe opening 221 is embedded in the heat insulation gasket 6. Specifically, in the first direction, the cross-sectional area of ​​the second pipe end 22 gradually increases as it moves further away from the first pipe end 21. During injection molding, the material used to form the heat insulation gasket 6 fully fills the outer and inner sides of the edge of the second pipe opening 221, thereby achieving a wrap-around connection. The thickness and material of the injection-molded heat insulation gasket 6 can be adjusted according to actual needs.

[0042] In some embodiments, please refer to Figure 2 and Figure 3 To enhance the stability of the heat insulation gasket 6, the heat insulation gasket 6 is made of high-temperature resistant plastic (abbreviated as PEEK). This high-temperature resistant plastic can specifically be a high-performance engineering plastic with high temperature resistance, because its thermal conductivity is as low as 0.2, which can effectively reduce the heat conducted from the second tube end 22 to other structures (such as the base 5 and the sealing gasket disposed between the base 5 and the second tube end 22).

[0043] In some embodiments, please refer to Figure 2 and Figure 3To improve the sealing performance between the heat insulation gasket 6 and the base 5, a sealing gasket 7 is added between the heat insulation gasket 6 and the base 5. Specifically, the heating element structure also includes a sealing gasket 7, which is sandwiched between the heat insulation gasket 6 and the base 5.

[0044] Specifically, the sealing gasket 7 can be made of silicone, which has good elasticity and sealing properties, and can further enhance the tightness of the connection between the heat insulation gasket 6 and the base 5. The silicone sealing gasket 7 can effectively fill the gap between the two, which may also include gaps caused by manufacturing errors of the tube body 2, the base 5, and the heat insulation gasket 6.

[0045] In some embodiments, please refer to Figure 4 To facilitate the assembly of the heating component 3, the heating component 3 has been optimized. Specifically, a portion of the heating element 31 is disposed within the mounting cavity 4 and encloses the outer wall of the tube body 2, while another portion extends outside the mounting cavity 4. Furthermore, the heating component 3 also includes a conductive plate 32 and a main control board 33; the conductive plate 32 is disposed outside the mounting cavity 4 and electrically connected to the heating element 31; the main control board 33 is disposed outside the mounting cavity 4 and electrically connected to the conductive plate 32. The conductive plate 32 and the heating element 31 are electrically connected via a first elastic conductive member 34, which at least abuts against one of the conductive plate 32 and the heating element 31; and / or, the main control board 33 and the conductive plate 32 are electrically connected via a second elastic conductive member 35, which at least abuts against one of the main control board 33 and the conductive plate 32.

[0046] The first elastic conductive element 34 and the second elastic conductive element 35 can be understood as PFC wiring harness boards. The elastic conductive element in the heating assembly 3 may only have the first elastic conductive element 34, or only have the second elastic conductive element 35, or have both the first elastic conductive element 34 and the second elastic conductive element 35. Furthermore, the first elastic conductive element 34 may only abut against the conductive plate 32, or only abut against the heating element 31, or abut against both the conductive plate 32 and the heating element 31; the second elastic conductive element 35 may only abut against the main control board 33, or only abut against the conductive plate 32, or abut against both the main control board 33 and the conductive plate 32.

[0047] The abutting arrangement of the first elastic conductive element 34 and the second elastic conductive element 35 reduces the amount of welding and improves the assembly efficiency of the heating component 3. Furthermore, since the first elastic conductive element 34 and the second elastic conductive element 35 not only conduct electricity but also provide elastic contact, they can effectively compensate for poor contact caused by manufacturing tolerances or assembly errors during assembly. Therefore, the elastic conductive element can be understood as a conductive structure similar to a spring, possessing good elasticity and conductivity, capable of accommodating deformation caused by assembly errors or thermal expansion and contraction while ensuring electrical connection.

[0048] It should be noted that the embodiments of this utility model do not limit the specific shapes of the first elastic conductive element 34 and the second elastic conductive element 35; furthermore, the structures of the first elastic conductive element 34 and the second elastic conductive element 35 can be the same or different. For example, the first elastic conductive element 34 can be made of metal spring sheet to provide higher elastic modulus and conductivity; while the second elastic conductive element 35 can be made of flexible conductive rubber to accommodate a wider range of assembly tolerances. This differentiated design can ensure the reliability of electrical connections while taking into account the assembly requirements between different components. Alternatively, the first elastic conductive element 34 and the second elastic conductive element 35 can both adopt the same structural design, for example, both can be made of metal spring sheet with good conductivity. This unified design approach can not only simplify the production process and reduce manufacturing costs, but also improve the versatility of parts, facilitating subsequent maintenance and replacement.

[0049] This embodiment of the invention optimizes the structural design of the heating element 3, specifically through the abutment setting of the elastic conductive component, thereby reducing the amount of welding and improving assembly efficiency. Simultaneously, the elastic properties of the conductive component effectively compensate for errors generated during component manufacturing or assembly, ensuring a stable connection between the heating element 31 and the main control board 33.

[0050] The heating principle of the heating component 3 for the tube body 2 is as follows: the main control board 33 sends a control signal to the conductive plate 32 according to the preset heating program. After receiving the signal, the conductive plate 32 transmits the current to the heating element 31. The heating element 31 generates heat under the action of the current. Since the heating element 31 penetrates the base 5 and is partially wrapped around the outer wall of the tube body 2, its heat will be conducted to the tube body 2 and then transferred to the aerosol rod inside the tube body 2.

[0051] In some embodiments, please refer to Figure 4 To improve assembly efficiency while enhancing conductivity stability, the connection between the first elastic conductive element 34 and the second elastic conductive element 35 was further optimized. Specifically, the first elastic conductive element 34 is welded to the conductive plate 32 and abuts against the heating element 31; and / or, the second elastic conductive element 35 is welded to the main control board 33 and abuts against the conductive plate 32.

[0052] Due to the welding and abutment design of the first elastic conductive element 34 and the second elastic conductive element 35, the heating component 3 can achieve a stable connection more quickly during assembly, while reducing performance problems caused by poor contact. In addition, by welding and fixing the connection points and then using the elastic properties of the elastic conductive element itself for dynamic compensation, the loosening or displacement of components that may occur during long-term use can be effectively addressed.

[0053] In some embodiments, please refer to Figure 4 Both the first elastic conductive element 34 and the second elastic conductive element 35 are formed by bending conductive metal sheets. The welding area of ​​the first elastic conductive element 34 and the second elastic conductive element 35 is designed as a planar structure, while the contact area is formed as a bent elastic structure. The planar structure of the welding area is beneficial to increasing the welding area, while the bent contact area can provide better elastic contact performance.

[0054] In some embodiments, please refer to Figure 4 In order for the conductive plate 32 to be electrically connected to other components, it needs to be adapted to the shape and assembly position of other components. Therefore, the conductive plate 32 is designed to be flexible. Furthermore, the flexibility of the conductive plate 32 facilitates bending into corresponding structures.

[0055] Furthermore, to stabilize the shape and position of the conductive plate 32, an additional support frame 36 is provided for the heating assembly 3. Specifically, the support frame 36 is disposed outside the mounting cavity 4 of the housing 1 to support the conductive plate 32.

[0056] In practice, multiple support frames 36 can be installed, as shown in the figure, with one support frame 36 installed on each side of the conductive plate 32 to support both sides of the conductive plate 32. The structural design of each support frame 36 must be adapted to the shape of the conductive plate 32 to ensure uniform distribution of the supporting force.

[0057] This embodiment of the invention provides stable support for the conductive plate 32 through the support frame 36, preventing the conductive plate 32 from affecting the connection stability with the heating element 31 or other components due to its own elastic deformation. In addition, the support frame 36 also provides a certain degree of protection, reducing the impact of external impacts or vibrations on the conductive plate 32 and its connecting components, thereby improving the overall reliability of the heating assembly 3.

[0058] This utility model also provides an aerosol generating device, which includes a housing and a heating element structure provided in any of the above embodiments. Please refer to [link / reference needed]. Figures 1 to 4The outer casing is located on the outside of the heating element structure, forming a complete aerosol generating device together. The casing's design not only houses and protects the heating element structure but also optimizes the user's grip experience through its specific shape and material. For example, the casing can be made of lightweight and durable materials with a frosted surface to increase friction and prevent slippage during use.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
