The technical solution in the embodiment of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiment of the present invention.

As used in the specification of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0030] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] See also Figure 1-6 As shown, this embodiment discloses an aerosol heating device based on heat conduction, comprising: an outer shell 1, a fixed cylinder 2 and a heating element 3; the outer shell 1 is provided with a accommodating cavity 11, and the fixed cylinder 2 is arranged in the accommodating cavity 11; both ends of the fixed cylinder 2 are open, the heating element 3 is connected to an open end of the fixed cylinder 2 and extends into the fixed cylinder 2, and the open end of the fixed cylinder 2 away from the heating element 3 is connected to the outer shell 1.

[0032] During specific implementation, the heating body, the fixed tube 2 and the outer shell 1 are connected in sequence, and the aerosol generating matrix enters the fixed tube 2 from the open end on one side where the fixed tube 2 is connected to the outer shell 1. The heating body heats the aerosol generating matrix in the fixed tube 2 by combining heat conduction with heat convection and heat radiation, so that the aerosol generating matrix is ​​heated to generate aerosol.

[0033] The aerosol heating device based on heat conduction in this embodiment physically isolates the heat generated by the heating element 3 by providing a fixed tube 2, thereby blocking the path of direct heat transfer to the outer shell 1, and connecting the fixed tube 2 to the outer shell 1 at the end away from the heating element 3. While ensuring the connection stability of the heating element 3, the heat transfer path is optimized to avoid overheating due to the close distance between the outer shell 1 and the heating element 3, effectively reducing the temperature of the outer shell 1 and avoiding the user from getting hot when holding the outer shell 1, which helps the user to maintain a high level of comfort when using the aerosol heating device for a long time. In addition, the optimization of the heat transfer path greatly reduces the loss of heat energy, improves the efficiency of heat energy utilization, and reduces the energy consumption of electric energy, which helps to reduce the number of times the aerosol heating device is charged, thereby reducing the frequency of user operations, improving the user's experience, and enhancing the attractiveness and market competitiveness of the atomizer product.

[0034] Specifically, there is a gap between the outer wall of the fixed tube 2 and the inner wall of the outer shell 1. The air or other medium between the outer wall of the fixed tube 2 and the inner wall of the outer shell 1 has a certain heat capacity and can absorb part of the heat, so that when the heating element 3 generates heat, a temperature gradient is generated inside and outside the fixed tube 2, so that the heat is gradually reduced during the transfer process, and then the heat is attenuated before being transferred to the outer shell 1. At the same time, part of the energy absorbed by the medium between the outer wall of the fixed tube 2 and the inner wall of the outer shell 1 can limit the loss of heat in the fixed tube 2, so as to maintain a certain heating temperature and improve the utilization efficiency of thermal energy.

[0035] Specifically, there is a gap between the heating element 3 and the inner wall of the fixed tube 2. The gap between the outer wall of the heating element 3 and the inner wall of the fixed tube 2 allows air or other media to exist between the heating element 3 and the fixed tube 2, so that the heat generated by the heating element 3 is transferred to the aerosol generating matrix through the air or other media in the fixed tube 2; at the same time, the inner wall of the fixed tube 2 radiates the heat generated by the heating element 3, which is convenient for heat energy recovery and improves the efficiency of heat energy utilization. The fixed tube 2 is set outside the heating element 3, which limits the flow of air or other media in the fixed tube 2 to the outside of the fixed tube 2, thereby reducing the occurrence of heat convection, and further saving the electric energy required by the heating element 3, effectively reducing the energy waste of the atomizer during use, having good environmental benefits, and playing a positive role in promoting sustainable development.

[0036] Specifically, the aerosol heating device based on heat conduction of this embodiment also includes: a fixed seat 4; the fixed seat 4 is connected to the open end of the heating element 3 away from the outer shell 1, and the heating element 3 is connected to the fixed seat 4; the fixed seat 4 is provided with a through hole 41, and the heating element 3 extends from the through hole 41 to the fixed tube 2. The use of the fixed seat 4 makes the connection between the heating element 3 and the fixed tube 2 more standardized, which is convenient for large-scale production and assembly, which can not only reduce the production cost, but also improve the reliability and consistency of the atomizer product. The heating element 3 is connected to the fixed tube 2 through the fixed seat 4, so that the heating element 3, the fixed seat 4 and the fixed tube 2 are independent of each other, which is convenient for disassembly and maintenance. When any structure of the heating element 3, the fixed seat 4 and the fixed tube 2 is damaged or fails, only the corresponding structure needs to be replaced, saving maintenance costs and resources.

[0037] Specifically, the heating element 3 is provided with a connecting portion 31 and a heating portion 32. The connecting portion 31 is connected to the fixing seat 4. The area of ​​one side of the connecting portion 31 close to the fixing cylinder 2 is larger than the radial cross-sectional area of ​​the through hole 41. The connecting portion 31 is provided with a through hole (not marked in the figure) arranged opposite to the through hole 41. The outer wall of the heating portion 32 is sealedly connected to the connecting portion 31, and extends from the connecting portion 31 through the through hole 41 to the fixing cylinder 2. The connecting portion 31 is used to cover the through hole 41 to prevent the air or other medium in the fixing cylinder 2 from flowing into the accommodating cavity 11 through the gap between the heating portion 32 and the through hole 41, thereby improving the heat recovery efficiency in the fixing cylinder 2 and ensuring the heating efficiency of the aerosol generating matrix.

[0038] Specifically, the through hole 41 adapts to the outer shape of the heating part 32. In the present embodiment, the heating part 32 is columnar, and the through hole 41 is a circular hole. The through hole 41 adapts to the outer shape of the heating part 32, which ensures the smooth loading and unloading of the heating part 32, and also avoids the heating part 32 being scratched or damaged by the edge of the through hole 41 during the loading and unloading process. At the same time, it can also avoid the heat loss caused by the larger gap between the heating part 32 and the through hole 41 due to the mismatch in shape. It can be understood that in other embodiments, the outer shape of the heating part 32 can be adjusted according to actual needs. By adjusting the size and shape of the heating part 32 and the through hole 41, the fixing seat 4 can be easily adapted to heating elements 3 of different specifications and models, so that the aerosol heating device has higher flexibility and scalability, and can meet the needs of different users and application scenarios.

[0039] Specifically, the heating part 32 is made of metal. Metal materials have high thermal conductivity and can quickly conduct heat to the fixed cylinder 2, so that the aerosol generating matrix in the fixed cylinder 2 is quickly heated, thereby improving the heating efficiency and heating effect of the aerosol generating matrix; and metal materials have good mechanical strength and toughness, so that the heating part 32 can withstand certain physical stress and thermal stress, thereby extending the service life of the heating element 3; in addition, metal materials can be made into various shapes and sizes through a variety of processing methods, such as casting, forging, machining, etc., to meet the design requirements of different aerosol heating devices based on heat conduction.

[0040] Specifically, the end of the heating portion 32 away from the connecting portion 31 is pointed. Due to the tip effect, the heat can be more concentrated at the end of the heating portion 32, which helps to transfer the heat to the aerosol generating substrate more effectively, thereby improving the heating efficiency and speed.

[0041] Specifically, a connecting groove 42 is provided at one end of the through hole 41 away from the fixed tube 2, and the groove width of the connecting groove 42 is greater than the aperture of the through hole 41, and the connecting portion 31 is embedded in the connecting groove 42 and is firmly connected to the fixing seat 4. The connecting portion 31 is embedded in the connecting groove 42 to form a tight mechanical connection with the connecting groove 42, which can significantly improve the stability of the structure. During the operation of the aerosol heating device, the heating element 3 generates heat, which may cause thermal expansion or vibration of the components. The close fit between the connecting portion 31 and the connecting groove 42 can effectively resist the unstable influence caused by external factors, ensuring that the overall structure remains stable. The embedding of the connecting portion 31 in the connecting groove 42 can also cover the gap between the through hole 41 and the heating portion 32, which helps prevent air or other media from leaking out from the connection and reduces heat energy loss.

[0042] Specifically, the connection groove 42 is adapted to the shape of the connection part 31. In this embodiment, the connection part 31 is in a cuboid shape, and the connection groove 42 is a square groove. The connection groove 42 is adapted to the shape of the connection part 31, which ensures the smooth loading and unloading of the connection part 31, and also avoids the connection part 31 being scratched or damaged by the edge of the through hole 41 during the loading and unloading process. At the same time, it can also ensure the close fit between the connection part 31 and the connection groove 42, thereby reducing heat loss. It is understandable that in other embodiments, the shape of the connection part 31 can be adjusted according to actual needs.

[0043] Specifically, the heating element 3 is also provided with a heating circuit (not shown) and a lead 33, the heating circuit is electrically connected to the lead 33, and the lead 33 extends from the heating circuit to the side of the connecting portion 31 away from the fixed cylinder 2. The lead 33 is a channel for the current to enter the heating circuit, ensuring a stable connection between the heating circuit and the power supply. The heating circuit can convert the power supply into electrical energy suitable for the heating element 3, so that the heating element 3 can generate heat through current conduction, thereby heating the aerosol generation matrix in the fixed cylinder 2.

[0044] In this embodiment, the heating temperature of the heating element 3 is 280°C-350°C. The temperature of 280°C-350°C can heat the aerosol generating matrix to an ideal state. Within this temperature range, the aerosol generating matrix can be fully pyrolyzed and produce rich aerosols, while avoiding the generation of harmful substances caused by excessively high temperatures, and will not produce excessive stimulation or bad taste, and can ensure that the aerosol has a soft and delicate taste, thereby improving the user experience.

[0045] Specifically, the fixing seat 4 is made of a high-temperature resistant plastic material. The high-temperature resistant plastic material has excellent thermal stability, can maintain the stability of physical and chemical properties in a high-temperature environment, and is not easily deformed, melted, or produces harmful substances due to high temperature, thereby ensuring the long-term safety and reliability of the aerosol heating device; and compared with traditional materials such as metal, the high-temperature resistant plastic has a lighter weight, which helps to reduce the overall weight of the aerosol heating device. The lightweight design makes the aerosol heating device easy to carry and use, and improves user popularity; in addition, the high-temperature resistant plastic material is easy to process and shape, and can be made into components of various shapes and sizes through injection molding, extrusion and other processes, which helps to reduce production costs, improve production efficiency, and meet diverse design requirements.

[0046] In this embodiment, the fixing base 4 can withstand a high temperature range of 280°C-360°C. The fixing base 4 can withstand a high temperature range of 280°C-360°C, which is greater than the heating temperature range of the heating element 3, so that the fixing base 4 can be suitable for connecting the heating element 3 and blocking the fixing tube 2 to prevent heat transfer.

[0047] Specifically, the fixing tube 2 is made of high temperature resistant plastic material. The fixing tube 2 and the fixing seat 4 are both made of high temperature resistant plastic material, which has the above-mentioned characteristics of thermal stability, light weight, and easy processing, and will not be described in detail here.

[0048] In this embodiment, the high temperature range that the fixed tube 2 can withstand is 280°C-360°C. The fixed tube 2 can withstand the high temperature range of 280°C-360°C, which is greater than the heating temperature range of the heating element 3, so that the fixed tube 2 can be used to cover the heating element 3 to radiate the heat generated by the heating element 3 inwardly and isolate it from the outside, thereby improving the efficiency of heat energy utilization.

[0049] Specifically, the outer shell 1 is provided with an operation hole 12, which is interconnected with the accommodating cavity 11, and the operation hole 12 is used to allow the aerosol generating substrate to enter the fixed cylinder 2 for heating. The operation hole 12 serves as a passage for the aerosol generating substrate to enter the fixed cylinder 2, ensuring that the substrate can smoothly enter the heating area for heating, so that the user can conveniently and accurately align the aerosol generating substrate with the heating element 3 to meet the heating requirements of the aerosol generating substrate.

[0050] Specifically, a limiting groove 13 is provided on the side of the operation hole 12 away from the accommodating cavity 11, and the groove width of the limiting groove 13 is greater than the aperture of the operation hole 12; a protrusion 21 is provided on the edge of the end of the fixed cylinder 2 away from the heating element 3, and the protrusion 21 abuts against the limiting groove 13. The limiting groove 13 and the operation hole 12 form a step structure, and the protrusion 21 abuts against the step structure, so that the fixed cylinder 2 cannot fall from the operation hole 12 into the accommodating cavity 11, and the connection stability with the outer shell 1 is maintained.

[0051] Specifically, the fixed cylinder 2 can be detachably connected, bonded, welded, connected by mortise and tenon joints or riveted to the outer shell 1. Different connection methods between the fixed cylinder 2 and the outer shell 1 can be selected according to actual needs or the shapes and sizes of the heating element 3 and the fixed cylinder 2, thereby improving the flexibility and adaptability of the aerosol heating device, and avoiding the mismatch between the fixed cylinder 2 and the outer shell 1, which causes the heating element 3 to move during use and cause poor contact or breakage. Therefore, the diversified connection structure design effectively improves the connection stability between the fixed cylinder 2 and the outer shell 1, thereby improving the stability of the heating element 3, reducing the loosening phenomenon caused by vibration or frequent operation during use, and improving the durability and reliability of the aerosol heating device.

[0052] In an optional embodiment, the fixed cylinder 2 is detachably connected to the outer shell 1. For example, the protrusion 21 is snapped with the limiting groove 13 through a snap-fit ​​structure, the fixed cylinder 2 is snapped with the operating hole 12 through a snap-fit ​​structure, or the outer side of the fixed cylinder 2 and the operating hole 12 are threaded and the fixed cylinder 2 and the operating hole 12 are screwed together, or the protrusion 21 is screwed with the limiting groove 13 through a screw. The fixed cylinder 2 is connected to the outer shell 1 in a detachable connection, which facilitates the installation and removal of the fixed cylinder 2, the maintenance and replacement of parts, and also improves the flexibility and maintainability of the aerosol heating device.

[0053] In an optional embodiment, the fixed cylinder 2 is bonded to the outer shell 1. Specifically, the side of the protrusion 21 close to the accommodating cavity 11 is bonded to the limiting groove 13, or the outer wall of the fixed cylinder 2 is bonded to the operating hole 12. The bonding method has the advantages of simple process and low cost, and can provide a relatively stable connection effect between the fixed cylinder 2 and the heating element 3, effectively reducing the difficulty of production and processing of the aerosol heating device.

[0054] In an optional embodiment, the fixing tube 2 is welded to the outer shell 1. Specifically, the protrusion 21 is welded to the limiting groove 13, or the outer wall of the fixing tube 2 is welded to the operating hole 12. The fixing tube 2 is connected to the outer shell 1 by welding, which greatly improves the connection stability of the fixing tube 2, and the welding method also has high durability and reliability, which can ensure the long-term operation stability of the aerosol heating device.

[0055] In an optional embodiment, the fixing tube 2 is connected to the outer shell 1 by mortise and tenon. For example, the fixing tube 2 is provided with a tenon, and the limiting groove 13 is provided with a mortise, and the tenon and the mortise engage with each other. The fixing tube 2 is connected to the outer shell 1 by mortise and tenon connection, without relying on additional connectors such as screws, glue, etc., which not only simplifies the assembly process and reduces material costs, but also avoids the risk of connection failure due to loosening or corrosion of connectors. The mortise and tenon connection provides excellent stability and durability with a unique concave-convex structure of the tenon and the mortise, making the aerosol heating device more sturdy and durable.

[0056] In an optional embodiment, the fixed cylinder 2 is riveted to the outer shell 1. Specifically, the protrusion 21 is riveted to the limiting groove 13, so that the protrusion 21 is tightly matched with the limiting groove 13, or the outer wall of the fixed cylinder 2 is clamped to the inner wall of the operating hole 12, so that the fixed cylinder 2 is tightly matched with the operating hole 12. The fixed cylinder 2 is connected to the outer shell 1 by riveting, and there is no need to assemble additional connectors and set a connecting structure, which saves resources and thus reduces the production cost of the aerosol heating device. The riveting has good shock resistance and impact resistance, which can ensure the stability of the fixed cylinder 2 and the heating element 3 during use.

[0057] Specifically, the aerosol heating device based on heat conduction of this embodiment also includes: a battery 5; the battery 5 is connected to the outer shell 1 and is located on the side of the heating element 3 away from the fixed cylinder 2, and the heating element 3 is electrically connected to the battery 5. More specifically, the lead 33 of the heating element 3 is electrically connected to the battery 5. The heating element 3 is electrically connected to the battery 5, forming a complete circuit loop, ensuring the normal operation of the aerosol heating device. The battery 5 is arranged on the side of the heating element 3 away from the fixed cylinder 2 and the operating hole 12, that is, the distance between the battery 5 and the heating element 3 is short, and the path for the electric energy to be transmitted from the battery 5 to the heating element 3 is greatly shortened, so that the loss of current during the transmission process is reduced, and more electric energy can be directly used for heating, thereby improving the overall energy utilization efficiency, and the reduction in energy consumption also extends the service life of the battery 5. At the same time, it reduces the number of charging times of the aerosol heating device, thereby reducing the frequency of user operations and improving the user's experience. The arrangement of the battery 5 close to the heating element 3 makes the overall structure more compact, helps to reduce the size and weight of the device, makes the aerosol heating device more portable, and improves the atomizer product in all aspects such as vision, touch and operation, thereby improving the attractiveness and market competitiveness of the atomizer product.

[0058] Specifically, the aerosol heating device based on heat conduction of this embodiment further includes: a control board 6; the control board 6 is connected to the outer shell 1, and the battery 5 is electrically connected to the control board 6. The control board 6 is used to monitor the status of the aerosol heating device and the atomizer, and to manage the use of the battery 5 and the temperature adjustment of the heating element 3, which can ensure the safety and stability of the aerosol heating device in different use environments. In addition, the control board 6 can combine the temperature control technology to optimize the working efficiency of the heating element 3 and further improve the overall performance of the atomizer product.

[0059] The present embodiment provides an aerosol heating device based on heat conduction, which physically isolates the heat generated by the heating element by providing a fixed tube, thereby blocking the path of direct heat transfer to the outer shell, and connecting the fixed tube to the outer shell at one end away from the heating element. While ensuring the connection stability of the heating element, the heat transfer path is optimized to avoid overheating due to the close distance between the outer shell and the heating element, effectively reducing the temperature of the outer shell and avoiding the user's hands getting hot when holding the outer shell, which helps the user to maintain a high level of comfort when using the aerosol heating device for a long time. The optimization of the heat transfer path greatly reduces the loss of heat energy, improves the efficiency of heat energy utilization, and reduces the energy consumption of electric energy, which helps to reduce the number of times the aerosol heating device is charged, thereby reducing the frequency of user operations, improving the user's experience, and enhancing the attractiveness and market competitiveness of the atomizer product.
