[0038] As described in the background, the heating structure is a key component in the aerosol production device to realize the functions of heating and atomization, and its main function is to heat the aerosol substrate to achieve effective atomization. However, the heating effect of the heating structure in the related art is restricted by factors such as the shape of the heating wire and the assembly position accuracy. In order to achieve good heating effect, the shape of the heating wire is often designed to be more complex, and such complex design not only increases the manufacturing difficulty, but also significantly increases the manufacturing cost.

[0039] Referring toFigures 1 to 6 In order to solve the above problems, according to one aspect of the present application, the embodiments of the present application provide a heating structure, which comprises a heating element 100 and a heat equalizing element 200, wherein the heating element 100 is used for generating heat; the heat equalizing element 200 is used for keeping uniform temperature, and the heat equalizing element 200 has a mounting channel 210, and the heating element 100 is mounted in the mounting channel 210 and conducts the generated heat to the heat equalizing element 200.

[0040] In the embodiments of the present application, the heating element 100 is a heating wire, the heating wire can generate heat by being electrified, and the material of the heating wire includes but is not limited to titanium wire, iron-nickel alloy wire, SUS316 stainless steel wire, SUS904 stainless steel wire, tungsten wire, constantan alloy wire, manganese-copper alloy wire, germanium-manganese-copper alloy wire, nickel-chromium alloy wire, iron-chromium-aluminum alloy wire, carbon wire, etc.; the heat equalizing element 200 is a heat equalizing structure, and the material of the heat equalizing element 200 includes but is not limited to aluminum nitride, diamond, silicon nitride, beryllium oxide, aluminum oxide, magnesium oxide, composite ceramic, metal-ceramic composite material, etc.

[0041] When the heating structure of the present application generates heat, the heat generated by the heating element 100 is first conducted to the heat equalizing element 200, and after the heat equalizing element 200 receives the heat, the whole body is quickly kept at uniform temperature; based on the design that the heating element 100 is mounted in the mounting channel 210, the heating structure can conduct heat to the outside through the heat equalizing element 200; at the same time, based on the characteristic that the heat equalizing element 200 can quickly keep the whole body at uniform temperature after receiving the heat, the heating structure can realize uniform and regular temperature distribution; in this case, even if the shape of the heating element 100 is designed as a simple shape, it will not affect the temperature distribution of the heating structure. By using the heat equalizing element 200 in the present application, not only can a heating structure with uniform and regular temperature distribution be obtained, so as to realize more uniform and controllable baking effect, but also the shape complexity of the heating element 100 can be reduced, so as to reduce the manufacturing difficulty and manufacturing cost of the heating element 100 and the heating structure, and the practicability of the heating structure is enhanced. In addition, the heat equalizing element 200 also plays a role of mounting the heating element 100.

[0042] With reference to Figure 1 , Figure 2 and Figure 4 , in one embodiment, the heating element 100 has a positive electrode end and a negative electrode end, and the heating element 100 comprises a main body part 110, and the positive electrode end and the negative electrode end are both arranged on the main body part 110; the heat equalizing element 200 is an insulating structure.

[0043] When the heating element 100 in the present application needs to generate heat, first, the positive electrode end is electrically connected with the power supply positive electrode, and the negative electrode end is electrically connected with the power supply negative electrode, and the heating element 100 will generate heat after being powered on. The design of the heat equalizing element 200 as an insulating structure not only can effectively prevent current leakage, reduce the risk of electric shock, and improve the safety of the heating structure, but also can protect the heating element 100, reduce thermal stress caused by temperature changes, and prolong the service life of the heating structure.

[0044] Referring to Figures 1 to 6 In an embodiment, the main body part 110 includes a first heating body 111, the first heating body 111 is in a linear structure, and the positive electrode end or the negative electrode end is arranged on the first heating body 111; the mounting channel 210 includes a first mounting hole 211, and the first heating body 111 is mounted in the first mounting hole 211.

[0045] In the present embodiment, the shape of the first heating body 111 is a straight rod or a straight bar shape; part of the structure of the first heating body 111 is mounted in the first mounting hole 211, and the other part of the structure is located outside the first mounting hole 211, and meanwhile, the end of the first heating body 111 away from the first mounting hole 211 is formed as the positive electrode end. In other embodiments, the end of the first heating body 111 away from the first mounting hole 211 can also be formed as the negative electrode end.

[0046] The design of the first heating body 111 in a linear structure not only reduces the structural complexity of the heating element 100, thereby reducing the manufacturing difficulty and cost of the heating element 100, but also helps the first heating body 111 to achieve uniform heating and avoid generating hot spots; in addition, the above design also facilitates the arrangement of the first heating body 111 in a limited space, which helps to reduce the volume of the heating structure. The first mounting hole 211 provided provides a mounting place for the first heating body 111.

[0048] In the present embodiment, the shape of the second heating body 112 is a straight rod or a straight bar shape; part of the structure of the second heating body 112 is mounted in the second mounting hole 212, and the other part of the structure is located outside the second mounting hole 212, and meanwhile, the end of the second heating body 112 away from the second mounting hole 212 is formed as the negative electrode end. In other embodiments, the end of the second heating body 112 away from the second mounting hole 212 can also be formed as the positive electrode end.

[0049] The second heating body 112 is arranged to increase the contact area between the heating part 100 and the heat equalizing part 200, thereby improving the heat conduction efficiency. The second heating body 112 is designed in a linear structure, which not only reduces the structural complexity of the heating part 100, thereby reducing the manufacturing difficulty and cost of the heating part 100, but also helps the second heating body 112 to realize uniform heating and avoid hot spots. In addition, the above design also facilitates the arrangement of the second heating body 112 in a limited space, which helps to reduce the volume of the heating structure. The second mounting hole 212 provides a mounting place for the second heating body 112.

[0050] Referring to Figures 1 to 6 In an embodiment, the second mounting hole 212 and the first mounting hole 211 are in communication. In this embodiment, the first mounting hole 211 and the second mounting hole 212 can be directly in communication and form a mounting area, in which case the first heating body 111 and the second heating body 112 are both mounted in the mounting area; in other embodiments, the first mounting hole 211 and the second mounting hole 212 can also be in communication through an intermediate hole, in which case the first heating body 111 is mounted in the first mounting hole 211 and the second heating body 112 is mounted in the second mounting hole 212. This design of the second mounting hole 212 in communication with the first mounting hole 211 helps to connect the first heating body 111 and the second heating body 112, thereby ensuring that the positive and negative terminals of the heating part 100 form a loop.

[0051] Referring to Figures 1 to 6 In an embodiment, the heating part 100 further comprises a connecting part 120, the first heating body 111 and the second heating body 112 are connected through the connecting part 120, and the connecting part 120 is in a linear structure; the mounting channel 210 further comprises a connecting hole 213, the connecting part 120 is mounted in the connecting hole 213, and the first mounting hole 211 and the second mounting hole 212 are in communication through the connecting hole 213.

[0052] In the embodiment, the connecting portion 120 is in the shape of a straight rod or a straight strip; the first end of the connecting portion 120 is connected with the first heating body 111, and the second end of the connecting portion 120 is connected with the second heating body 112. The connecting portion 120 not only plays a connecting role, ensuring that the positive and negative ends form a loop, but also helps to increase the contact area between the heating member 100 and the heat spreading member 200, thereby improving the heat conduction efficiency. The linear structure of the connecting portion 120 not only reduces the structural complexity of the heating member 100, thereby reducing the manufacturing difficulty and cost of the heating member 100, but also helps the connecting portion 120 to achieve uniform heating and avoid the generation of hot spots. In addition, the above design also facilitates the arrangement of the connecting portion 120 in a limited space, which helps to reduce the volume of the heating structure. The third mounting hole not only provides a mounting place for the connecting portion 120, but also enables the first mounting hole 211 and the second mounting hole 212 to communicate. In addition, in other embodiments, the first heating body 111 and the second heating body 112 can also be directly connected.

[0053] Referring to Figures 1 to 6 In an embodiment, the first heating body 111 is in close contact with the hole wall of the first mounting hole 211. The above design not only increases the contact area between the first heating body 111 and the heat spreading member 200, thereby improving the heat conduction efficiency, but also helps the hole wall of the first mounting hole 211 to achieve uniform heat distribution and avoid the generation of hot spots. In addition, the above design also enhances the stability of the first heating body 111 on the heat spreading member 200, reducing the possibility of displacement of the first heating body 111 due to vibration or external impact.

[0054] Referring to Figures 1 to 6 In an embodiment, the second heating body 112 is in close contact with the hole wall of the second mounting hole 212.

In addition, the above design also enhances the stability of the second heating body 112 on the heat spreading member 200, reducing the possibility of displacement of the second heating body 112 due to vibration or external impact.

[0055] Referring to Figures 1 to 6 In an embodiment, the connecting portion 120 is in close contact with the hole wall of the connecting hole 213. The above design not only increases the contact area between the connecting portion 120 and the heat spreading member 200, thereby improving the heat conduction efficiency, but also helps the hole wall of the connecting hole 213 to achieve uniform heat distribution and avoid the generation of hot spots. In addition, the above design also enhances the stability of the connecting portion 120 on the heat spreading member 200, reducing the possibility of displacement of the connecting portion 120 due to vibration or external impact.

[0056] Referring to Figures 1 to 6 In an embodiment, the first mounting hole 211 and the second mounting hole 212 are spaced apart. This design not only helps to space apart the first heating body 111 and the second heating body 112, thereby effectively avoiding short circuit of the positive electrode terminal and the negative electrode terminal due to contact, improving the safety of the heating structure, but also helps to increase the contact area of the heating member 100 and the heat spreading member 200, thereby improving the heat conduction efficiency.

[0057] Referring to Figures 1 to 6 In an embodiment, the first mounting hole 211 is arranged along the length direction of the heat spreading member 200. This design not only helps to increase the contact area of the first heating body 111 and the heat spreading member 200, but also enables the first heating body 111 to more effectively transfer heat to the heat spreading member 200, thereby improving the thermal efficiency of the first heating body 111; in addition, this design also effectively enhances the stability of the first heating body 111 on the heat spreading member 200, reducing the possibility of displacement of the first heating body 111 due to vibration or external impact.

[0058] Referring to Figures 1 to 6 In an embodiment, the second mounting hole 212 is arranged along the length direction of the heat spreading member 200. This design not only helps to increase the contact area of the second heating body 112 and the heat spreading member 200, but also enables the second heating body 112 to more effectively transfer heat to the heat spreading member 200, thereby improving the thermal efficiency of the second heating body 112; in addition, this design also effectively enhances the stability of the second heating body 112 on the heat spreading member 200, reducing the possibility of displacement of the second heating body 112 due to vibration or external impact.

[0059] Referring to Figures 1 to 6 In an embodiment, the first mounting hole 211 penetrates through the heat spreading member 200. In this embodiment, the first mounting hole 211 is a through hole. This design not only helps to further increase the contact area of the first heating body 111 and the heat spreading member 200, but also helps to further enhance the stability of the first heating body 111 on the heat spreading member 200.

[0060] Referring to Figures 1 to 6 In an embodiment, the second mounting hole 212 penetrates through the heat spreading member 200. In this embodiment, the second mounting hole 212 is a through hole. This design not only helps to further increase the contact area of the second heating body 112 and the heat spreading member 200, but also helps to further enhance the stability of the second heating body 112 on the heat spreading member 200. In addition, when the first mounting hole 211 penetrates through the heat spreading member 200 and the second mounting hole 212 penetrates through the heat spreading member 200, the connecting hole 213 is arranged on the surface of the heat spreading member 200 to communicate the first mounting hole 211 and the second mounting hole 212.

[0061] Referring to Figures 1 to 6 In an embodiment, one of the first mounting hole 211 and the second mounting hole 212 is arranged on the first surface 220 of the heat spreading member 200, and the connecting hole 213 is arranged on the second surface 230 of the heat spreading member 200, and the first surface 220 of the heat spreading member 200 and the second surface 230 of the heat spreading member 200 are arranged adjacently.

[0062] In the embodiment, the length direction of the first mounting hole 211 coincides with the axial direction of the heat spreading member, and the second mounting hole 212 is arranged on the first surface 220 of the heat spreading member 200; in other embodiments, the length direction of the second mounting hole 212 can also coincide with the axial direction of the heat spreading member, and the first mounting hole 211 is arranged on the first surface 220 of the heat spreading member 200. The above design helps to increase the spacing between the first heat generating body 111 and the second heat generating body 112, thereby helping to increase the contact area between the heat generating member 100 and the heat spreading member 200.

[0063] Referring to Figures 7 to 10 In an embodiment, the heat generating structure further comprises a protective shell 300, and the protective shell 300 is a heat conducting structure; the protective shell 300 has a protective space 330, and the heat spreading member 200 is installed in the protective space 330.

[0064] In the embodiment, the material of the protective shell 300 can be any one of metal, ceramic or glass, and when the material of the protective shell 300 is metal, the material of the protective shell 300 includes but is not limited to stainless steel, aluminum alloy, aluminum bronze alloy, titanium aluminum alloy, magnesium aluminum alloy, magnesium alloy, titanium alloy, Kovar alloy, copper alloy, and ceramic aluminum alloy. In this case, the connection mode of the heat spreading member 200 and the protective shell 300 includes but is not limited to riveting mode, buckle mode, brazing mode, or the mode of making the protective shell 300 heat expand and then sleeving on the peripheral surface of the heat spreading member 200 to fix the heat spreading member 200 in the protective space 330.

[0065] When the material of the protective shell 300 is ceramic, the material of the protective shell 300 includes but is not limited to zirconia, YSZ (English full name: Yttria-Stabilized Zirconia, Chinese name: yttria-stabilized zirconia), ZTA (English full name: Zirconia Toughened Alumina, Chinese name: zirconia toughened alumina), alumina, mullite, cordierite, sapphire, spinel, yttrium oxide, germanium oxide and other ceramics or other composite ceramics, and cermet. In this case, the connection mode of the heat spreading member 200 and the protective shell 300 includes but is not limited to high-temperature bonding of potting adhesive, active soldering, silicate glass bonding, or clamping connection by filling elastic sheet.

[0066] When the material of the protective shell 300 is glass, the material of the protective shell 300 includes but is not limited to quartz glass, silicate glass, borosilicate glass, aluminosilicate glass, lithium aluminosilicate glass, magnesium aluminosilicate glass, or microcrystalline glass of the corresponding component system. In this case, the connection mode of the heat uniforming member 200 and the protective shell 300 includes but is not limited to high-temperature bonding by pouring glue, brazing by active welding material, silicate glass bonding, or clamping connection by filling elastic sheet.

[0067] In addition, the protective space 330 has a protection opening through which the heat uniforming member 200 is installed into the protective space 330; at the same time, the heat uniforming member 200 is completely located in the protective space 330, and the length of the heat uniforming member 200 is less than the length of the protective space 330; the protective shell 300 has a blocking cover capable of blocking the protection opening to prevent the aerosol substrate and other roasted substances from entering the protective space 330. The protective space 330 not only provides a mounting place for the heat uniforming member 200, but also provides protection for the heat uniforming member 200 and the heating member 100, avoiding corrosion caused by direct contact between the aerosol substrate and the heat uniforming member 200 and the heating member 100, and prolonging the service life of the heat uniforming member 200 and the heating member 100.

[0068] Reference Figure 9 In an embodiment, the heat uniforming member 200 is attached to the inner wall surface of the protective space 330 to conduct heat to the protective shell 300.

[0069] In the embodiment, the heat uniforming member 200 and the inner wall surface of the protective space 330 are preferably seamlessly attached or almost seamlessly attached, so that the inner wall surface of the protective space 330 can form a compressive stress on the surface of the heat uniforming member 200; in other embodiments, the heat uniforming member 200 and the inner wall surface of the protective space 330 can also be attached and connected through an annular boss on the surface of the heat uniforming member 200 and the inner wall surface of the protective space 330; in this case, if the material of the protective shell 300 is metal, the inner wall surface of the protective space 330 needs to be blackened in advance to prevent the inner wall surface of the protective space 330 from reflecting infrared heat and making it difficult to conduct heat outward; if the material of the protective shell 300 is ceramic or glass, the infrared transmission performance of the protective shell 300 is appropriately improved. The attachment of the heat uniforming member 200 and the inner wall surface of the protective space 330 not only helps to increase the contact area between the heat uniforming member 200 and the inner wall surface of the protective space 330, thereby improving the heat conduction efficiency, but also helps to achieve uniform heat distribution of the inner wall surface of the protective space 330, avoiding the generation of hot spots; in addition, the above design also enhances the stability of the heat uniforming member 200 in the protective space 330, reducing the possibility of displacement of the heat uniforming member 200 due to vibration or external impact.
