Description

Technical Field

[0001] This invention relates to the field of heating device technology, and in particular to a heat exchange mechanism and a heating device including the heat exchange mechanism. Background Technology

[0002] In recent years, with the continuous improvement of living standards, the requirements for heating equipment have gradually increased. Under the premise of energy conservation and emission reduction, how to optimize heating equipment to achieve the best heating effect has become the research and development focus of various heating equipment on the market. Among heating equipment, heating the heating element through heating electrodes to generate heat, and then convection with the air to heat the airflow, is a commonly used heating method. However, the heating electrodes used in existing heating equipment are mostly independent electrode rings, with simple structures and limited heating effects. They cannot conduct electricity and heat multiple areas simultaneously. If multiple heating elements are to be heated, multiple independent electrode rings need to be set up, which is complicated to assemble and requires various fixing components in the subsequent assembly process. Moreover, the fixing components for fixing electrodes in existing heating equipment are relatively simple and cannot guarantee the overall protection and fixation of the electrodes. During use and transportation, if the electrodes are not fixed stably, problems such as vertical and circumferential shaking of the electrodes are prone to occur, leading to poor contact.

[0003] Meanwhile, in existing heating modules, the heating element and the heat conductor are generally connected by direct fixing or plugging. There is no heat-conducting spring structure between the heating element and the heat conductor that can elastically deform under stress. Furthermore, due to errors in the production process of the heating element and the heat conductor, dimensional inconsistencies can occur, making it easy to encounter installation difficulties when directly assembling the heating element and the heat conductor. In addition, the ceramic heating modules used in existing heating devices are relatively brittle and prone to breakage, and may deform under heat. If the heating element and the heat conductor are directly assembled and contacted, the heat conductor may deform under heat, causing the heating element to break. Moreover, direct contact between the heating element and the heat conductor during assembly or transportation can also lead to breakage of either the heating element or the heat conductor.

[0004] In existing heating modules, air guiding and concentrating devices are commonly used to change the airflow path. However, the concentrating part of existing air concentrating devices is mostly planar, which can only guide the airflow but cannot collect it. At the same time, existing air concentrating devices and heating devices are mostly assembled with snap-fit ​​structures, but snap-fit ​​structures are prone to jamming during assembly, making disassembly and assembly difficult. In addition, existing air concentrating devices usually only use snap-fit ​​structures for fixation, which cannot cope with the axial movement of components installed in the air concentrating device.

[0005] To address the above requirements, a heating device is needed that can collect airflow, modularly disassemble and reassemble, prevent internal components from shifting, and optimize heating efficiency. Summary of the Invention

[0006] To address at least one problem existing in the prior art, according to one aspect of the present invention, a heat exchange mechanism is provided. This mechanism increases the contact area with air through a heat conductor for sufficient heat exchange. A suitable number of heating elements are movably mounted on the heat conductor according to actual needs. A heat-conducting spring is installed in the buffer zone between the heating element and the mounting hole of the heating block, allowing for better heat transfer from the heating element to the heat conductor, thus maximizing heat exchange between the heat conductor and the air. Simultaneously, several mounting rings are provided on the electrode sleeve that fixes the heat conductor and heating element. The electrode rings on the electrode are accurately assembled into the mounting grooves of the mounting rings, enabling the electrode to be energized and operational in multiple positions. Furthermore, the electrode sleeve prevents leakage during electrode operation, ensuring the safety of the entire electrode assembly during operation. Simultaneously, the airflow is concentrated and gathered by the air-gathering section before passing through the heat conductor placed in the support section for heat exchange, increasing airflow concentration, preventing airflow loss, and improving heat exchange efficiency. Additionally, the snap-fit ​​groove on the support section, in conjunction with the limiting groove, engages and positions the heating module and the fixing frame installed in the air-gathering shroud, preventing axial movement of the heating module.

[0007] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0008] A heat exchange mechanism, comprising:

[0009] An electrode sheath includes a skeleton, several mounting rings, and several connecting parts. The mounting rings are set on the skeleton through the connecting parts. One end of each connecting part is connected to the skeleton. The extension line extending from the other end of each connecting part passes through the center of the electrode sheath. At least one mounting ring is provided on each connecting part. The mounting ring is provided with a mounting groove. The skeleton is provided with a mounting buckle.

[0010] An electrode comprises several electrode rings and several connecting rods. The electrode rings are connected by the connecting rods, and each connection is connected to at least one electrode ring. The extension lines of the connecting rods all pass through the center of the electrode. The electrode rings are installed in corresponding mounting slots.

[0011] The heating module includes a heat conductor and a heating element placed in a mounting hole of the heat conductor;

[0012] The mounting bracket includes a mounting bracket body. The outer side wall of the mounting bracket body is provided with a fastening groove and an elastic buckle. The mounting buckle is fastened to the fastening groove on the outer side wall of the mounting bracket body so that the mounting bracket and the electrode sheath are fitted together. The heating module is placed between the upper electrode sheath located above the mounting bracket body and the lower electrode sheath located below the mounting bracket body. The electrode is energized to heat the heating element in the heating module.

[0013] The wind concentrator has a mounting cavity for mounting a fixing bracket, and the inner wall of the wind concentrator has a snap-fit ​​groove for engaging with the elastic buckle.

[0014] The bracket includes a support plate and a circumferential vertical plate. The support plate is connected to the inner wall of the circumferential vertical plate. The support plate extends toward the center of the bracket and is an annular plate. The inner ring of the support plate is engaged with the support part.

[0015] Preferably, the heating module includes:

[0016] A heat conductor, with several mounting holes provided on it;

[0017] A heating element is provided, and several heating elements are placed in the mounting holes;

[0018] The heat-conducting spring includes a bent edge and a contact edge. The contact edge extends from the circumferential edge of the bent edge in a direction away from the bent edge. The contact edge and the bent edge are set at an angle. The contact edge includes a first contact portion connected to the bent edge, a second contact portion away from the bent edge, and a transition portion connecting the first contact portion and the second contact portion. The extension surfaces of the first contact portion and the second contact portion are on different planes. The contact edge can elastically deform relative to the bent edge when subjected to force. The heat-conducting spring is installed between the mounting hole on the heat conductor and the heating element. This design allows the heat conductor to increase its contact area with air for sufficient heat exchange. The heating element can be movably mounted on the heat conductor, and the heat-conducting spring is installed in the buffer zone between the heating block mounting hole and the heating element. This allows for better heat transfer from the heating element to the heat conductor, ensuring sufficient heat exchange between the heat conductor and the air. Simultaneously, the heat-conducting spring prevents poor contact caused by dimensional inconsistencies when the heat conductor and heating element are directly assembled, reducing thermal resistance and improving thermal conductivity. Furthermore, the heat-conducting spring prevents the heating element from cracking during production or transportation due to an unreasonable gap between the heat conductor and the heating element, or from cracking due to heat deformation of the heat conductor.

[0019] Preferably, a conductive ring is provided between the electrode ring and the heating element. One side of the conductive ring is in contact with the electrode ring, and the other side of the conductive ring is in contact with the end face of the heating element. Both upper and lower end faces of each heating element are in contact with a conductive ring. After the electrode ring is energized, it heats the heating element through the conductive ring. The heating element transfers heat to the heat conductor through the heat-conducting spring.

[0020] Preferably, it also includes a protective net, which is installed at the air outlet of the bracket, and the air outlet of the bracket is at one end near the surrounding part of the wind-collecting hood.

[0021] Preferably, the air-concentrating hood includes an air-concentrating part, a support part, and an enclosing part. The air-concentrating part is an annular component with an inner ring and an outer ring. The upper end of the support part is connected to the inner ring of the air-concentrating part, and the support part extends axially from the inner ring of the air-concentrating part along the air-concentrating hood. The enclosing part is connected to the lower end of the support part, and the enclosing part extends radially toward the center of the air-concentrating hood. The support part is located between the air-concentrating part and the enclosing part. The airflow passes through the air-concentrating part and the support part in sequence and flows out from the inner ring of the enclosing part. The inner wall of the support part is provided with a snap-fit ​​groove for engaging with an elastic buckle. The inner ring of the support part and the enclosing part form a mounting cavity for mounting a fixing bracket.

[0022] Preferably, the contact edge of the heat-conducting spring is inserted into the mounting hole of the heat conductor, and the contact edge of the heat-conducting spring is inserted between the heat conductor and the heating element. The outer wall of the first contact portion contacts the inner wall of the mounting hole on the heat conductor, and the bottom wall of the bent edge contacts the upper end face of the heat conductor. At the same time, the contact edge is sleeved on the heating element so that the inner wall of the second contact portion contacts the outer wall of the heating element. After the bottom wall of the bent edge contacts the upper end face of the heat conductor, the bent edge overlaps the heat conductor. The top wall of the bent edge contacts the end face of the electrode groove so that the bent edge is fixed between the electrode ring and the heat conductor to prevent the heat-conducting spring from moving up and down. Since the bent edge and the contact edge are not on the same plane, when the contact edge contacts the heating element during assembly, the heating element squeezes the second contact portion, causing the second contact portion to move outward. Through the transition portion, the first contact portion is driven to move outward, so that the outer wall of the first contact portion can be squeezed with the heat conductor, thereby increasing the contact area and reducing the thermal resistance. When the heat-conducting spring is assembled with the heat conductor and the heat-generating body, the first contact part, the transition part, and the second contact part enable the contact edge to undergo elastic deformation, preventing the heat-conducting spring from failing to be assembled between the heat-generating body and the heat conductor if there are dimensional deviations due to processing problems.

[0023] Preferably, the heating element is a ceramic graphene heating module containing graphene, and the centers of the mounting holes on the heat conductor are all distributed on concentric circles with the center of the heat conductor as the center.

[0024] Preferably, the thickness of the heat conductor along the axial direction is less than the thickness of the heating element along the axial direction. This arrangement ensures that one end face of the heating element is higher than the end face of the heat conductor on the same side, creating a height difference between the end faces of the heating element and the heat conductor. This creates a mounting area between the heating element and the heat conductor, facilitating the subsequent installation of the electrode sheath and providing a mounting position for the electrode sheath. It also allows the connecting part on the electrode sheath to be fitted into the mounting area formed by the height difference between the heat conductor and the heating element.

[0025] Preferably, the contact edge includes a plurality of spaced unit contact portions, with a gap area between each pair of adjacent unit contact portions, and each unit contact portion includes a first contact portion connected to the bending edge, a second contact portion away from the bending edge, and a transition portion connecting the first contact portion and the second contact portion.

[0026] Preferably, the width and height of each unit contact portion are equal. This ensures uniformity in the heat conduction process of the unit contact portion, resulting in consistent heat conduction at any position within the contact portion. Furthermore, the unit contact portions ensure that external forces experienced by the contact portion when in contact with the heat conductor and heat source are transferred to each unit contact portion, dispersing the external pressure on the contact edge. Simultaneously, the elastic deformation of the unit contact portion under stress is not affected by other unit contact portions; that is, multiple unit contact portions do not interfere with each other when under stress, thus ensuring that each unit contact portion can tightly adhere to its respective contacting component. If no spacing area is provided on the contact edge, the elastic deformation of different areas of the contact edge will inevitably affect each other, leading to some areas of the contact edge failing to tightly adhere to the heat source and heat conductor, resulting in poor contact and high thermal resistance.

[0027] Preferably, a central mounting ring is provided at the center of the electrode sheath, and several connecting parts are connected together at one end near the center of the electrode sheath through the central mounting ring. Each connecting part is provided with at least one circumferential mounting ring, and the centers of adjacent circumferential mounting rings are distributed on concentric circles with the center of the electrode sheath as the center. A central electrode ring is provided at the center of the electrode, and several connecting rods are connected together at one end near the center of the electrode through the central electrode ring. Each connecting rod is provided with at least one circumferential electrode ring, and the centers of adjacent circumferential electrode rings are distributed on concentric circles with the center of the electrode as the center.

[0028] Preferably, a support base and an inverted buckle are provided on the inner side wall of the main body of the fixing frame. The support base and the inverted buckle are respectively located near the two end faces of the main body of the fixing frame along the height direction. A limiting post is also provided on the outer side wall of the fixing frame, and a limiting groove is provided on the inner wall of the support part to cooperate with the limiting post. The limiting post includes a limiting plate connected to the outer side wall of the main body of the fixing frame and limiting inclined plates placed on both sides of the limiting plate. The limiting inclined plates can ensure that when the limiting post is engaged with the positioning hole on the air guide cover, the inclined surface of the limiting inclined plate can play a guiding role, so that the limiting post can be smoothly assembled with the positioning hole.

[0029] Preferably, the skeleton is a ring structure, with one end of each connecting part connected to the inner ring of the skeleton, and the extension line of the other end of each connecting part passing through the center of the skeleton.

[0030] Preferably, the mounting ring includes a bottom wall and an annular step, the annular bottom wall and the annular step forming a mounting groove, and the connecting part is connected to the outer wall of the annular step. This configuration allows the annular step on the mounting ring to protect and limit the electrode rings on the electrodes, thereby preventing the electrode rings and electrodes from moving in parallel. At the same time, it can limit the vertical movement of the conductive ring and heating element placed between the two electrode rings, as well as the heat-conducting spring between the heating element and the heat conductor.

[0031] Preferably, the connecting part is provided with an assembly groove for placing the connecting rod of the electrode. This arrangement allows the connecting rod on the electrode to be securely placed in the connecting part of the electrode sheath, thereby ensuring the protection of the connecting rod by the electrode sheath and preventing deformation of the electrode assembly due to the shaking of the connecting rod during movement.

[0032] Preferably, a raised rib is provided on the portion of the connecting part that connects to the outermost mounting ring away from the center of the electrode sheath. The raised rib extends in the direction towards the frame. The raised rib and the mounting groove are located on the same side of the electrode sheath, and the height of the raised rib is less than or equal to the height of the annular step. The raised rib extends to the edge of the frame. This arrangement enhances the strength of the connecting part and ensures that the electrode sheath will not break during use and transportation.

[0033] Preferably, the inverted clips are positioned near the upper surface of the main body of the fixing frame, and the support bases are positioned near the lower surface of the main body of the fixing frame. Several inverted clips are arranged on the same circle along the circumference of the main body of the fixing frame, and several support bases are also arranged on the same circle along the circumference of the main body of the fixing frame. This arrangement allows the heat conductor to be placed between the inverted clips and the support bases during installation, with the lower surface of the inverted clips abutting against the upper surface of the heat conductor, and the upper surface of the support base abutting against the lower surface of the heat conductor, thus ensuring stable support of the heat conductor by the support bases.

[0034] Preferably, an internal limiting strip is also provided on the inner side wall of the main body of the fixing frame, and the internal limiting strip extends from the center of the main body of the fixing frame in the height direction toward both ends of the main body of the fixing frame.

[0035] Preferably, the internal limiting strip is a long strip structure with an inclined surface at its upper end. This inclined surface slopes from the point where the internal limiting strip connects to the inner wall of the fixing frame body towards the lower end of the fixing frame body. The angle between the inclined surface and the inner wall of the fixing frame body located at the upper end of the internal limiting strip is an obtuse angle. After the heat conductor is assembled with the electrode sheath fixing assembly, the internal limiting strip on the fixing frame abuts against the outer wall of the heat conductor or engages with the limiting opening on the outer wall. This prevents the heat conductor from shifting. Simultaneously, the inclined upper end of the internal limiting strip guides the heat conductor during assembly with the fixing frame, preventing obstruction of installation if the upper end of the internal limiting strip is flat, thus ensuring smooth installation.

[0036] Preferably, the limiting groove protrudes from the side wall of the support portion toward the center away from the wind concentrator shroud, so that the limiting groove protrudes to the outside of the side wall of the support portion, forming a protrusion, and an assembly gap is formed between the protrusion of the limiting groove and the outside of the side wall of the support portion. This assembly gap can be used to abut against the support plate on the bracket for limiting, so that the support plate provides limiting support for the wind concentrator shroud.

[0037] In another aspect, the present invention provides a heating device, which includes a fan and a heat exchange mechanism as described above.

[0038] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0039] 1. The heat exchange mechanism of this invention gathers airflow into the heating module through a concentrator, and then energizes the electrodes to heat the heating module. The heating module increases its contact area with the air through a heat conductor for sufficient heat exchange. A heat-conducting spring is installed in the buffer zone between the heating block mounting hole and the heating element, which can better transfer the heat from the heating element to the heat conductor, thus maximizing the heat exchange between the heat conductor and the air. The heating element is a ceramic graphene heating module containing graphene, which gives the heating element good heating and heat transfer effects, as well as good thermal stability. This ensures that the heat output of the heating element remains very stable during long-term use, maximizing the transfer of heat to the heat conductor. During the assembly process, the second contact part of the heat-conducting spring is subjected to external force, and at the same time, the transition part drives the first contact part to move outward of the contact edge, so that the contact edge can produce elastic deformation. This allows the heat-conducting spring to adapt to heating elements and heat conductors with size differences due to processing issues.

[0040] 2. This invention provides a locking groove on the outer wall of the mounting bracket body and a support base and an inverted buckle on the inner wall of the mounting bracket body. This allows the mounting bracket to engage with the electrode sheath on the outside and support the heat conductor on the inside, ensuring protection of the electrode while preventing movement of the electrode and the heat conductor connected to the electrode. By installing the mounting bracket between the upper and lower electrode sheaths, the heat conductor and electrode are securely mounted within the space enclosed by the mounting bracket and the electrode sheaths, preventing movement of the electrode, heat conductor, and heating element.

[0041] 3. The electrode assembly of the present invention, by setting an mounting ring on the electrode sheath, accurately assembles the electrode ring on the electrode into the mounting groove of the mounting ring, thereby enabling the electrode to be energized and working in multiple positions. Furthermore, the electrode sheath can prevent leakage during the operation of the electrode, thus ensuring the safety of the entire electrode assembly during operation.

[0042] 4. The annular step on the electrode sheath mounting ring of the present invention protects and limits the electrode ring on the electrode, thereby preventing the electrode ring and the electrode from moving in series. At the same time, it can limit the conductive ring and heating element placed between the two electrode rings, as well as the heat-conducting spring between the heating element and the heat conductor, to prevent them from moving up and down.

[0043] 5. In the present invention, the wind-gathering part of the wind-gathering hood has a conical structure. The inner and outer rings of the wind-gathering part are at different heights along the axial direction. The angle between the axial cross-sectional profile of the wind-gathering part and the axis of the wind-gathering hood is an acute angle. This allows the wind-gathering part to change the direction of the airflow entering the wind-gathering hood, so that the airflow gathers at the air outlet of the wind-gathering part and enters the heating device in the support part to exchange heat with the heat conductor. This allows the heated airflow to flow out from the inner ring of the surrounding part.

[0044] 6. The snap-fit ​​groove on the support portion of the wind-concentrating hood in this invention, in conjunction with the limiting groove, completes the snap-fit ​​and positioning of the fixing frame installed in the wind-concentrating hood. The snap-fit ​​platform located in the snap-fit ​​groove is used to snap-fit ​​the snap-fit ​​arm on the elastic buckle. During assembly, the snap-fit ​​arm can snap into the gap between the snap-fit ​​platform and the bottom wall of the snap-fit ​​groove. The elastic buckle has elastic force, which facilitates snap-fit ​​and disengagement with the snap-fit ​​platform under external force, thus making the assembly and disassembly of the wind-concentrating hood more convenient. The surrounding portion in the wind-concentrating hood can also provide axial limiting support for the installation of the heating module, electrode sleeve, and fixing frame installed in the wind-concentrating hood, preventing axial movement of the heating device. At the same time, an assembly gap is formed between the protrusion of the limiting groove in the wind-concentrating hood and the outer side wall of the support portion. This assembly gap can be used to abut against the support plate on the bracket for limiting, so that the support plate provides limiting support for the wind-concentrating hood, ensuring the stability of the wind-concentrating hood and the bracket installation.

The support part 82 is located between the air-concentrating part 81 and the enclosing part 83. Airflow passes sequentially through the air-concentrating part 81 and the support part 82, and flows out from the inner ring of the enclosing part 83. The inner wall of the support part 82 is provided with an elastic buckle 616. The snap-fit ​​groove 821, the inner ring of the support portion 82, and the surrounding portion 83 form a mounting cavity for mounting the fixing bracket 6; the elastic buckle 616 includes a connecting arm 6161 connected to the outer wall of the fixing bracket body 61, and a U-shaped elastic portion 6162 connected to one end of the connecting arm 6161. One end of the U-shaped elastic portion 6162 extends away from the outer wall of the fixing bracket body 61, and the snap-fit ​​arm 6163 is perpendicular to or at an acute angle to the outer wall of the fixing bracket body 61.

[0087] The bracket 9 includes a support plate 92 and a circumferential vertical plate 91. The support plate 92 is connected to the inner wall of the circumferential vertical plate 91. The support plate 92 extends toward the center of the bracket 9 and is an annular plate. The inner ring of the support plate 92 is engaged with the support part 82. The protective net 10 is set at the air outlet of the bracket 9. The air outlet of the bracket 9 is at one end near the surrounding part 83 of the wind concentrator hood 8.

[0088] refer to Figure 12As shown, a support base 613 and an inverted buckle 612 are provided on the inner side wall of the main body 61 of the fixed frame. The support base 613 and the inverted buckle 612 are respectively located near the two end faces of the main body 61 of the fixed frame along the height direction. A limiting post 615 is also provided on the outer side wall of the fixed frame 6. A limiting groove 822 that mates with the limiting post 615 is provided on the inner wall of the support part 82. The limiting post 615 includes a limiting plate connected to the outer side wall of the main body 61 of the fixed frame and limiting inclined plates placed on both sides of the limiting plate. The limiting inclined plates can ensure that when the limiting post 615 is engaged with the positioning hole on the air guide cover, the inclined surface of the limiting inclined plate can play a guiding role, so that the limiting post 615 can be smoothly assembled with the positioning hole. The support base 613 and the inverted buckle 612 are staggered, meaning that the support base 613 and the inverted buckle 612 are positioned on different vertical lines perpendicular to the cross-section of the main body 61 of the fixed frame 6 along the height direction. This arrangement ensures that the support base 613 and the inverted buckle 612 are staggered, thereby increasing the number of contact points between the fixed frame 6 and the heat conductor 2 in the circumferential direction, and ensuring the proper engagement and support of the heat conductor 2 by the support base 613 and the inverted buckle 612.

[0089] The heating module is positioned between the upper electrode sleeve located above the main body 61 of the mounting bracket and the lower electrode sleeve located below the main body 61 of the mounting bracket. The upper and lower electrode rings 51 installed in the upper and lower electrode sleeves are respectively connected to the live and neutral wires, thereby energizing the electrodes 5 to heat the heating element 3 in the heating module. The mounting buckles 411 on the upper electrode sleeve engage with the upper buckle groove 611, and the mounting buckles 411 on the lower electrode sleeve engage with the lower buckle groove 611, thus ensuring that the mounting bracket 6 is securely installed between the upper and lower electrode sleeves 4.

[0090] refer to Figure 8-10As shown, the heating module includes: a heat conductor 2, a heating element 3, and a heat-conducting spring 1. The heat conductor 2 is provided with a plurality of mounting holes 21; a plurality of heating elements 3 are provided and are placed in the mounting holes 21; the heat-conducting spring 1 includes a bent edge 11 and a contact edge 12. The contact edge 12 extends from the circumferential edge of the bent edge 11 in a direction away from the bent edge 11. The contact edge 12 and the bent edge 11 are set at an angle. The contact edge 12 includes a first contact portion 121 connected to the bent edge 11, a second contact portion 123 away from the bent edge 11, and a transition portion 122 connecting the first contact portion 121 and the second contact portion 123. The extension surface of the first contact portion 121 and the extension surface of the second contact portion 123 are on different planes. The contact edge 12 can elastically deform relative to the bent edge 11 when subjected to force; the heat-conducting spring 1 is installed between the mounting holes 21 on the heat conductor 2 and the heating element 3. With this configuration, the heat conductor 2 can be used to increase the contact area with air for sufficient heat exchange. The heating element 3 can be movably mounted on the heat conductor 2. The heat-conducting spring 1 is installed in the buffer zone between the heating block mounting hole 21 and the heating element 3, which can better transfer the heat on the heating element 3 to the heat conductor 2, thereby enabling sufficient heat exchange between the heat conductor 2 and the air. At the same time, the heat-conducting spring 1 can avoid the problem of poor contact caused by inconsistent dimensions when the heat conductor 2 and the heating element 3 are directly assembled, thereby reducing thermal resistance and improving thermal conductivity. In addition, the heat-conducting spring 1 can also prevent the heating element 3 from breaking during production or transportation due to unreasonable gaps between the heat conductor 2 and the heating element 3, or the heating element 3 from breaking due to heat deformation of the heat conductor 2.

[0091] A conductive ring 7 is provided between the electrode ring 51 and the heating element 3. One side of the conductive ring 7 is in contact with the electrode ring 51, and the other side of the conductive ring 7 is in contact with the end face of the heating element 3. Both upper and lower end faces of each heating element 3 are in contact with a conductive ring 7. After the electrode ring 51 is energized, it heats the heating element 3 through the conductive ring 7. The heating element 3 transfers heat to the heat conductor 2 through the heat-conducting spring 1.

[0092] The electrode sleeve 4 is also provided with a mounting part 423, which is located on the side of the connecting part 42 between the central mounting ring 431 and the circumferential mounting ring 432. The mounting part 423 is provided with a mounting port, which is used to match the assembly hole on the heat conductor 2. The heat conductor 2 is further fixed between the two electrode sleeves 4 by a fastener passing through the mounting port and the assembly hole. The mounting part 423 includes a bottom wall and two side walls, both of which are connected to the connecting part 42. The side walls extend along the side opposite to the mounting groove 433 and extend towards the front of the electrode sleeve 4. The bottom wall is provided with a mounting port. The two side walls can enhance the strength of the mounting part 423, ensuring that the mounting part 423 has sufficient strength and stability during installation and use.

[0093] The contact edge 12 of the heat-conducting spring 1 is inserted into the mounting hole 21 of the heat conductor 2, and the contact edge 12 of the heat-conducting spring 1 is inserted between the heat conductor 2 and the heating element 3. The outer wall of the first contact part 121 contacts the inner wall of the mounting hole 21 on the heat conductor 2, and the bottom wall of the bent edge 11 contacts the upper end face of the heat conductor 2. At the same time, the contact edge 12 is sleeved on the heating element 3 so that the inner wall of the second contact part 123 contacts the outer wall of the heating element 3. After the bottom wall of the bent edge 11 contacts the upper end face of the heat conductor 2, the bent edge 11 overlaps the heat conductor 2. The top wall of the bent edge 11 contacts the end face of the groove of the electrode 5 so that the bent edge 11 is fixed between the electrode ring 51 and the heat conductor 2 to prevent the heat-conducting spring 1 from moving up and down. Since the bent edge 11 and the contact edge 12 are not on the same plane, when the contact edge 12 contacts the heating element 3 during assembly, the heating element 3 presses the second contact portion 123, causing the second contact portion 123 to move outward. This, in turn, causes the first contact portion 121 to move outward through the transition portion 122, allowing the outer wall of the first contact portion 121 to press against the heat conductor 2, thereby increasing the contact area and reducing thermal resistance. When the heat-conducting spring 1 is assembled with the heat conductor 2 and the heating element 3, the first contact portion 121, in conjunction with the transition portion 122 and the second contact portion 123, allows the contact edge 12 to undergo elastic deformation. This prevents the heat-conducting spring 1 from failing to assemble between the heating element 3 and the heat conductor 2 if dimensional deviations occur due to processing issues.

[0094] refer to Figure 10 As shown, the heat conductor 2 has several heat exchange holes that extend along the axial direction of the heat conductor 2, which has a honeycomb structure. The uniform arrangement of the heat exchange holes creates a honeycomb mesh on the heat conductor 2, increasing the contact area with air for efficient heat exchange.

[0095] refer to Figure 11 As shown, the heating element 3 is also provided with several heating holes 31. The heating holes 31 extend along the axial direction of the heating element 3. The heating element 3 has a honeycomb structure. The surface of the heating element 3 and the inner wall of the heating holes 31 are both made of graphene, which makes the heating element 3 have good heating and heat transfer effects and good thermal stability. This makes the heat power of the heating element 3 very stable during long-term use, and maximizes the transfer of heat to the heat conductor 2.

[0096] The mounting holes 21 on the heat conductor 2 are all distributed in concentric circles centered on the center of the heat conductor 2. This arrangement allows several heating elements 3 to be arranged in concentric circles, thereby improving the uniformity of heat conduction. The mounting holes 21 include a central mounting hole 211 located at the center of the heat conductor 2 and at least one layer of circumferential mounting holes 212. Each layer of circumferential mounting holes 212 includes at least two circumferential mounting holes 212, and the center of each circumferential mounting hole 212 in the same layer is equidistant from the center of the heat conductor 2. This arrangement allows the heating elements 3 to be movably mounted at the center of the heat conductor 2 and at circumferential positions at a certain distance from the center, thereby enabling the heating elements 3 to uniformly transfer heat to the central area and all radial areas of the heat conductor 2.

[0097] In this embodiment, the heat conductor 2 has a circular cross-sectional shape and seven mounting holes 21 are provided on the heat conductor 2, including a central mounting hole 211 located at the center of the heat conductor 2 and six circumferential mounting holes 212 located in the circumferential direction. The six circumferential mounting holes 212 are all at the same distance from the center of the heat conductor 2, and the distance between the center of the six mounting holes 21 and the center of the heat conductor 2 is half the radius of the heat conductor 2.

[0098] The number of heating elements 3 is less than or equal to the number of mounting holes 21 on the heat conductor 2. The number of heating elements 3 can be flexibly set according to actual needs, which can improve applicability when increasing or decreasing the number of heating elements 3.

[0099] The thickness of the heat conductor 2 along the axial direction is less than the thickness of the heating element 3 along the axial direction. This arrangement makes one end face of the heating element 3 higher than the end face of the heat conductor 2 on the same side, thus creating a height difference between the end faces of the heating element 3 and the heat conductor 2 on the same side. This creates a mounting area between the heating element 3 and the heat conductor 2, which facilitates the subsequent installation of the electrode sheath and provides a mounting position for the electrode sheath. It also allows the connecting part on the electrode sheath to be snapped into the mounting area formed by the height difference between the heat conductor 2 and the heating element 3.

[0100] The heat transfer holes 22 on the heat conductor 2 are hexagonal holes. The hexagonal holes ensure sufficient heat exchange area and also enhance the structural strength of the heat conductor 2, preventing damage and deformation of the heat conductor 2 during use and transportation.

[0101] refer to Figure 8As shown, the heat-conducting spring 1 is made of a heat-conducting metal material that can be elastically deformed. Preferably, in this embodiment, the heat-conducting spring 1 is made of an aluminum-based, copper-based, or iron-based material. The first contact portion 121, the transition portion 122, and the second contact portion 123 on the heat-conducting spring 1 are all straight plate structures. The extension surfaces of the first contact portion 121 and the second contact portion 123 are arranged parallel to each other, and both the first contact portion 121 and the second contact portion 123 can be tightly attached to their respective contacting components when subjected to external force. The transition portion 122 is inclined relative to the first contact portion 121 and the second contact portion 123. The angle at which the transition portion 122 is deflected relative to the first contact portion 121 is equal to the angle at which the transition portion 122 is deflected relative to the second contact portion 123. The angle between the transition portion 122 and the extended surface of the first contact portion 121 is α, where α is in the range of 0° < a ≤ 30°, meaning the angle at which the transition portion 122 deflects relative to the first contact portion 121 is α. The angle between the transition portion 122 and the extended surface of the second contact portion 123 is β, where β is in the range of 0° < b ≤ 30°, meaning the angle at which the transition portion 122 deflects relative to the second contact portion 123 is β.

[0102] The connection between the bent edge 11 and the first contact portion 121 is a rounded transition. This design prevents stress concentration between the bent edge 11 and the contact edge 12, ensuring that the connection between the bent edge 11 and the contact edge 12 will not easily break due to stress concentration when the contact edge 12 undergoes elastic deformation under external force. The bent edge 11 and the first contact portion 121 are set at a right angle. This design facilitates the tight fit of the bent edge 11 against the upper surface of the heat conductor 2 when the heat-conducting spring 1 is inserted into the mounting hole 21 of the heat conductor 2, while also ensuring a tight fit between the first contact portion 121 and the heat conductor 2. Furthermore, it ensures that when the contact edge 12 is subjected to external force, the entire side surface of the first contact portion 121 and the second contact portion 123 are in close contact with their respective contacting components, thereby ensuring the tightness of the contact edge 12's fit.

[0103] The contact edge 12 includes a plurality of spaced-apart unit contact portions, with a gap 124 between each pair of adjacent unit contact portions. Each unit contact portion includes a first contact portion 121 connected to the bent edge 11, a second contact portion 123 away from the bent edge 11, and a transition portion 122 connecting the first contact portion 121 and the second contact portion 123. The gap 124 extends from the edge of the bent edge 11 to the bottom of the contact edge 12.

[0104] The width and height of each unit contact portion are equal, ensuring uniformity in heat conduction and consistent heat conduction at any point. The unit contact portions also ensure that external forces experienced by the contact portion when in contact with the heat conductor 2 and the heating element 3 are transferred to each unit contact portion, dispersing the external pressure on the contact edge 12. Furthermore, the elastic deformation of the unit contact portion under stress is not affected by other unit contact portions, meaning that multiple unit contact portions do not interfere with each other under stress, allowing each unit contact portion to adhere tightly to its respective contacting component. If the contact edge 12 does not have a spacing region 124, the elastic deformation of different areas of the contact edge 12 will inevitably affect each other, leading to some areas of the contact edge 12 failing to adhere tightly to the heating element 3 and the heat conductor 2, resulting in poor contact and high thermal resistance. The spacing of the spacing regions 124 can be equal circumferentially, gradually increasing, gradually decreasing, or irregularly distributed. In this embodiment, the spacing of the spacing regions 124 is preferably equal.

[0105] The bent edge 11 is an annular component, and the contact edge 12 extends from the inner edge of the bent edge 11 in a direction away from the bent edge 11. The bent edge 11 is designed according to the heating element 3 and the heat conductor 2 used with it, and the cross-sectional shape of the bent edge 11 can be triangular, circular, or polygonal. In this embodiment, the cross-section of the bent edge 11 is preferably circular, that is, the axial projection of the bent edge 11 is annular.

[0106] A notch area 111 is provided on the bent edge 11, forming two opposite ends of the bent edge 11 within the notch area 111. This design breaks the bent edge 11 into an unclosed structure, thus giving it circumferential elastic deformation capability. This design allows the notch area 111 to cooperate with the spacer area 124 to accommodate the slightly different sizes of the heating element 3 and the heat conductor 2. In particular, the notch area 111 provides sufficient deformation capability when the bent edge 11 is assembled between the heating element 3 and the heat conductor 2, avoiding problems such as poor contact leading to high thermal resistance during installation. This design also prevents the bent edge 11 from being unable to elastically deform when it is a fully enclosed annular structure, thus preventing the heat-conducting spring 1 from being unable to adapt to the heating element 3 and the heat conductor 2, which may have inconsistent dimensions due to manufacturing errors.

[0107] The extension of the centerline of the notch area 111 passes through the center of the bent edge 11, and the notch area 111 on the bent edge 11 is connected to the interval area 124. This arrangement makes the entire heat-conducting spring 1 form an open structure from the bent edge 11 to the contact edge 12 in the notch area 111, ensuring that the bent edge 11 of the heat-conducting spring 1 can drive the contact edge 12 to undergo circumferential elastic deformation when it undergoes elastic deformation, so as to adapt to the slightly different sizes of the heat-generating body 3 and the heat-conducting body 2.

[0108] refer to Figure 12 As shown, the axial height of the connecting portion 42 on the electrode sleeve 4 is less than or equal to the height of the mounting ring 43. This design ensures that after the electrode sleeve 4 is assembled with the heating element 3, the connecting portion 42 can be smoothly engaged in the mounting area formed by the height difference between the heating element 3 and the heat conductor 2. The extension line of each connecting portion 42 passes through the center of the mounting ring 43 to which it is connected, and the extension line of each connecting rod 52 passes through the center of the electrode ring 51 to which it is connected.

[0109] The electrode ring 51 is corrugated. This design gives the electrode ring 51 elastic deformation, increases the adaptability of installation gaps, and prevents poor contact.

[0110] A central mounting ring 431 is provided at the center of the electrode sheath 4. Several connecting parts 42 are connected together at their ends near the center of the electrode sheath 4 through the central mounting ring 431. Each connecting part 42 is provided with at least one circumferential mounting ring 432. The centers of adjacent circumferential mounting rings 432 are distributed on concentric circles with the center of the electrode sheath 4 as the center. That is, the circumferential mounting rings 432 located on the same circle are equidistant from the central mounting ring 431.

[0111] refer to Figure 13 As shown, a central electrode ring 511 is disposed at the center of electrode 5. Several connecting rods 52 are connected together at their ends near the center of electrode 5 via the central electrode ring 511. Each connecting rod 52 is provided with at least one circumferential electrode ring 512. The centers of adjacent circumferential electrode rings 512 are distributed on concentric circles with the center of electrode 5 as the center. That is, the circumferential electrode rings 512 located on the same circle are equidistant from the central electrode ring 511. This arrangement allows the electrode sheath 4 to be provided with mounting rings 43 at the center position and at a certain distance from the center, thereby enabling the electrode sheath 4 to fit the central electrode ring 511 and the circumferential electrode rings 512 on electrode 5, ensuring that the electrode 5 assembly can perform conductive work in both the central region and the circumferential region at a certain distance from the center.

[0112] In this embodiment, mounting rings 43 are evenly spaced on the same circle with the center of the electrode sheath 4 as the center, and the included angle between each pair of adjacent connecting parts 42 is equal. Preferably, the mounting rings 43 include a central mounting ring 431 and six circumferential mounting rings 432 with their centers on the same circle. The included angle between each pair of connecting parts 42 is 60°, and the included angle between the lines connecting the centers of each pair of circumferential mounting rings 432 to the center of the electrode sheath 4 is 60°. Correspondingly, electrode rings 51 are evenly spaced on the same circle with the center of the electrode 5 as the center, and the included angle between each pair of adjacent connecting rods 52 is equal. Each electrode ring 51 includes a central electrode ring 511 and six circumferential electrode rings 512 with their centers on the same circle. The included angle between each pair of connecting rods 52 is 60°, and the included angle between the centers of each pair of circumferential electrode rings 512 to the center of the electrode 5 is 60°. The circumferential mounting ring 432 divides the connecting portion 42 connected to it into several segments. Since the mounting ring 43 includes a central mounting ring 431 and a circumferential mounting ring 432 on each connecting portion 42, the circumferential mounting ring 432 on each connecting portion 42 divides the connecting portion 42 into two segments. These two segments of the connecting portion 42 are located on opposite sides of the circumferential mounting ring 432. The two ends of one segment of the connecting portion 42 are connected to the outer wall of the central mounting ring 431 and the outer wall of the circumferential mounting ring 432, respectively. One end of the other segment of the connecting portion 42 is connected to the outer wall of the circumferential mounting ring 432, and the other end is connected to the frame 41.

[0113] The circumferential mounting ring 432 divides the connecting part 42 connected to it into several segments, and the extension line of the connecting part 42 connected to the skeleton 41 can pass through the center of the electrode sheath 4, that is, the connecting part 42 divided into several segments are all on the same straight line.

[0114] The frame 41 has a ring-shaped structure, and one end of each connecting part 42 is connected to the inner ring of the frame 41. The extension line of the other end of each connecting part 42 passes through the center of the frame 41. Preferably, the frame 41 has a circular ring-shaped structure, which ensures that any point on the frame 41 is equidistant from the center of the electrode sheath 4, thereby ensuring the consistency of the length of each connecting part 42, and at the same time, the connecting parts 42 cooperate with the frame 41 to enhance the overall strength of the electrode sheath 4.

[0115] The mounting ring 43 includes a bottom wall and an annular step 4332. The annular bottom wall 4331 and the annular step 4332 form a mounting groove 433, and the connecting part 42 is connected to the outer wall of the annular step 4332. The bottom wall is annular 4331, and a through hole is provided on the annular bottom wall 4331. The inner diameter of the through hole is less than or equal to the inner diameter of the electrode ring 51, and the outer diameter of the annular bottom wall 4331 is greater than or equal to the outer diameter of the electrode ring 51. This arrangement ensures that after the electrode ring 51 is placed in the mounting groove 433, the bottom wall of the mounting ring 43 can cover the electrode ring 51, preventing the electrode ring 51 from contacting external components and thus causing leakage. At the same time, the annular step 4332 on the mounting ring 43 protects and limits the electrode ring 51 on the electrode 5, thereby preventing the electrode ring 51 and the electrode 5 from moving in series. It can also limit the movement of the conductive ring 7 and the heating element 3 placed between the two electrode rings 51, and the heat-conducting spring 1 between the heating element 3 and the heat conductor 2, preventing them from moving up and down.

[0116] The connecting part 42 is provided with an assembly groove 421 for placing the connecting rod 52 of the electrode 5. This arrangement allows the connecting rod 52 on the electrode 5 to be stably placed in the connecting part 42 of the electrode sleeve 4, thereby ensuring the protection of the connecting rod 52 by the electrode sleeve 4 and preventing deformation of the electrode 5 assembly due to shaking of the connecting rod 52 during movement.

[0117] The mounting groove 421 on the connecting part 42 communicates with the mounting groove 433. The connection point between the mounting groove 421 and the mounting groove 433 is located at the connection point between the connecting part 42 and the electrode ring 51. This arrangement allows the connecting rod 52 connecting the electrode ring 51 to be smoothly inserted into the mounting groove 421.

[0118] A protrusion 422 is provided on the portion of the connecting part 42 that connects to the outermost mounting ring 43 away from the center of the electrode sheath 4. The protrusion 422 extends in the direction toward the frame 41. The protrusion 422 and the mounting groove 433 are located on the same side of the electrode sheath 4, and the height of the protrusion 422 is less than or equal to the height of the annular step 4332. The protrusion 422 extends to the edge of the frame 41. This arrangement enhances the strength of the connecting part 42 and ensures that the electrode sheath 4 will not break during use and transportation.

[0119] The frame 41 is also provided with a limiting step 412. The limiting step 412 is used to abut against the end face of the fixing frame 6, which can enhance the strength of the frame 41. During the installation of the electrode sheath 4 and the fixing frame 6, the limiting step 412 applies pressure to the fixing frame 6, thereby supporting the frame 41 and preventing local deformation when the electrode sheath 4 and the fixing frame 6 are fastened together.

[0120] refer to Figure 15As shown, the support base 613 and the inverted buckle 612 on the mounting bracket 6 have different shapes. This design facilitates the differentiation of the upper and lower positions of the mounting bracket during installation, thereby better positioning and assembly with the upper and lower electrode sleeves 4. The upper end face of the inverted buckle 612 is inclined. This design ensures that when the heat conductor 2 is assembled with the mounting bracket 6, the heat conductor 2 can smoothly enter under the inverted buckle 612 through the inclined surface, thus allowing the inverted buckle 612 to be fastened to the upper end face of the heat conductor 2.

[0121] The main body 61 of the fixing frame is a ring-shaped component. In this preferred embodiment, the main body 61 of the fixing frame is a circular ring-shaped component. This design allows the fixing frame 6 to have good elastic deformation capability, thereby better assembling with the electrode sheath 4 and completely wrapping the outer wall of the heat conductor 2.

[0122] The buckle groove 611 includes an upper buckle groove 611 near the upper end face of the fixing frame body 61 and a lower buckle groove 611 near the lower end face of the fixing frame body 61. The upper buckle groove 611 includes a plurality of buckle grooves 611 on the same circle, and the lower buckle groove 611 includes a plurality of buckle grooves 611 on the same circle.

[0123] The upper and lower retaining grooves 611 are arranged opposite to each other or staggered. If the upper and lower retaining grooves 611 are arranged opposite to each other, they are located on the same axial section. If the upper and lower retaining grooves 611 are staggered, they are located on different axial sections.

[0124] The upper and lower buckle slots 611 are staggered. This arrangement ensures that the mounting buckles 411 on the upper electrode sleeve that are fastened to the upper buckle slot 611 and the mounting buckles 411 on the lower electrode sleeve that are fastened to the lower buckle slot 611 will not interfere with each other, preventing collisions between the mounting buckles 411 on the two electrode sleeves 4. It also ensures that the mounting buckles 411 have sufficient length to fasten to the buckle slot 611, while reducing the height of the fixing frame body 61, thereby reducing the size of the electrode sleeve 4 fixing assembly and making the electrode sleeve 4 fixing assembly more compact.

[0125] An inverted buckle 612 is positioned near the upper surface of the main body 61 of the fixing frame, and a support base 613 is positioned near the lower surface of the main body 61 of the fixing frame. Several inverted buckles 612 and several support bases 613 are arranged on the same circle along the circumference of the main body 61 of the fixing frame. This arrangement allows the heat conductor 2 to be placed between the inverted buckles 612 and the support bases 613 during installation, with the lower surface of the inverted buckle 612 abutting against the upper surface of the heat conductor 2, and the upper surface of the support base 613 abutting against the lower surface of the heat conductor 2, thus ensuring that the support base 613 can stably support the heat conductor 2.

[0126] An internal limiting strip 614 is also provided on the inner sidewall of the fixing frame body 61. The internal limiting strip 614 extends from the center of the fixing frame body 61 in the height direction towards both ends of the fixing frame body 61. The internal limiting strip 614 is a long strip structure. The upper end surface of the internal limiting strip 614 is an inclined surface. The inclined surface is inclined from the position where the internal limiting strip 614 connects to the inner sidewall of the fixing frame body 61 towards the lower end surface of the fixing frame body 61. The angle between the inclined surface and the inner sidewall of the fixing frame body 61 located at the upper end of the internal limiting strip 614 is an obtuse angle. After the heat conductor 2 is assembled with the electrode sheath 4 fixing assembly, the internal limiting strip 614 on the fixing frame 6 abuts against the outer wall of the heat conductor 2 or engages with the limiting port on the outer wall, thereby preventing the heat conductor 2 from moving around. At the same time, the upper end surface of the internal limiting strip 614 is set as an inclined surface to ensure that the inclined surface can guide the heat conductor 2 during the assembly process with the fixing frame 6, preventing the installation of the heat conductor 2 from being obstructed when the upper end surface of the internal limiting strip 614 is flat, and ensuring the smoothness of the installation process.

[0127] The support base 613 and the buckle 612 on the main body 61 of the fixing frame are staggered, that is, the support base 613 and the buckle 612 are set on different vertical lines perpendicular to the cross section of the main body 61 of the fixing frame along the height direction of the fixing frame 6. This arrangement can ensure that the support base 613 and the buckle 612 are staggered, thereby increasing the number of contact points between the fixing frame 6 and the heat conductor 2 in the circumferential direction, and ensuring that the support base 613 and the buckle 612 can engage and support the heat conductor 2.

[0128] The support base 613 and the inverted clip 612 have different shapes. This design facilitates the differentiation of the upper and lower positions of the mounting bracket during installation, thereby better positioning and assembly with the upper and lower electrode sleeves 4. The upper end face of the inverted clip 612 is beveled. This design ensures that when the heat conductor 2 is assembled with the fixing bracket 6, the heat conductor 2 can smoothly enter under the inverted clip 612 through the beveled surface, thus allowing the inverted clip 612 to be fastened to the upper end face of the heat conductor 2.

[0129] The main body 61 of the fixing frame is a ring-shaped component. In this preferred embodiment, the main body 61 of the fixing frame is a circular ring-shaped component. This design allows the fixing frame 6 to have good elastic deformation capability, thereby better assembling with the electrode sheath 4 and completely wrapping the outer wall of the heat conductor 2.

[0130] The buckle groove 611 includes an upper buckle groove 611 near the upper end face of the fixing frame body 61 and a lower buckle groove 611 near the lower end face of the fixing frame body 61. The upper buckle groove 611 includes a plurality of buckle grooves 611 on the same circle, and the lower buckle groove 611 includes a plurality of buckle grooves 611 on the same circle.

[0131] The upper and lower retaining grooves 611 are arranged opposite to each other or staggered. If the upper and lower retaining grooves 611 are arranged opposite to each other, they are located on the same axial section. If the upper and lower retaining grooves 611 are staggered, they are located on different axial sections.

[0132] The upper and lower buckle slots 611 are staggered. This arrangement ensures that the mounting buckles 411 on the upper electrode sleeve that are fastened to the upper buckle slot 611 and the mounting buckles 411 on the lower electrode sleeve that are fastened to the lower buckle slot 611 will not interfere with each other, preventing collisions between the mounting buckles 411 on the two electrode sleeves 4. It also ensures that the mounting buckles 411 have sufficient length to fasten to the buckle slot 611, while reducing the height of the fixing frame body 61, thereby reducing the size of the electrode sleeve 4 fixing assembly and making the electrode sleeve 4 fixing assembly more compact.

[0133] An inverted buckle 612 is positioned near the upper surface of the main body 61 of the fixing frame, and a support base 613 is positioned near the lower surface of the main body 61 of the fixing frame. Several inverted buckles 612 and several support bases 613 are arranged on the same circle along the circumference of the main body 61 of the fixing frame. This arrangement allows the heat conductor 2 to be placed between the inverted buckles 612 and the support bases 613 during installation, with the lower surface of the inverted buckle 612 abutting against the upper surface of the heat conductor 2, and the upper surface of the support base 613 abutting against the lower surface of the heat conductor 2, thus ensuring that the support base 613 can stably support the heat conductor 2.

[0134] An internal limiting strip 614 is also provided on the inner sidewall of the fixing frame body 61. The internal limiting strip 614 extends from the center of the fixing frame body 61 in the height direction towards both ends of the fixing frame body 61. The internal limiting strip 614 is a long strip structure. The upper end surface of the internal limiting strip 614 is an inclined surface. The inclined surface is inclined from the position where the internal limiting strip 614 connects to the inner sidewall of the fixing frame body 61 towards the lower end surface of the fixing frame body 61. The angle between the inclined surface and the inner sidewall of the fixing frame body 61 located at the upper end of the internal limiting strip 614 is an obtuse angle. After the heat conductor 2 is assembled with the electrode sheath 4 fixing assembly, the internal limiting strip 614 on the fixing frame 6 abuts against the outer wall of the heat conductor 2 or engages with the limiting port on the outer wall, thereby preventing the heat conductor 2 from moving around. At the same time, the upper end surface of the internal limiting strip 614 is set as an inclined surface to ensure that the inclined surface can guide the heat conductor 2 during the assembly process with the fixing frame 6, preventing the installation of the heat conductor 2 from being obstructed when the upper end surface of the internal limiting strip 614 is flat, and ensuring the smoothness of the installation process.

[0135] The outer wall of the main body 61 of the fixed frame is also provided with an elastic buckle 616 and a limiting post 615. The elastic buckle 616 and the limiting post 615 are respectively used to engage with the locking groove 821 and the limiting hole on the inner wall of the wind concentrator 8. The elastic buckle 616 includes a connecting arm 6161 connected to the outer wall of the main body 61 of the fixed frame, and a U-shaped elastic part 6162 connected to one end of the connecting arm 6161. One end of the U-shaped elastic part 6162 extends away from the outer wall of the main body 61 of the fixed frame and the locking arm 6163 is perpendicular to or at an acute angle to the outer wall of the main body 61 of the fixed frame. The limiting post 615 includes a limiting plate connected to the outer wall of the main body 61 of the fixed frame and limiting inclined plates placed on both sides of the limiting plate. The limiting inclined plates can ensure that when the limiting post 615 is engaged with the positioning hole on the wind guide hood, the inclined surface of the limiting inclined plate can play a guiding role, so that the limiting post 615 can be smoothly assembled with the positioning hole.

[0136] In this embodiment, the outer ring of the air-gathering part 81 is the airflow inlet, and the inner ring of the surrounding part 83 is the airflow outlet. When the airflow passes through the air-gathering part 81, the air-gathering part 81 will concentrate and gather the airflow before it passes through the heat conductor 2 placed in the support part 82 for heat exchange, and then blow it out through the air outlet at the surrounding part 83. This improves the concentration of the airflow, prevents airflow loss, and improves the heat exchange efficiency. The snap-fit ​​groove 821 and the limiting groove 822 are used to fix and limit the fixing frame 6 used to fix the heat conductor 2, respectively, so that the heating device with the heat conductor 2 and the heating element 3 is stably installed in the support part 82 of the air-gathering hood 8.

[0137] The air-concentrating hood 8 also includes a connecting platform 84, which extends axially from or near the outer ring of the air-concentrating part 81. This arrangement allows the connecting platform 84 to engage with the locking platform 93 on the bracket 9, with the lower end face of the locking platform 93 engaging with the upper end face of the connecting platform 84, ensuring a secure connection between the air-concentrating hood 8 and the bracket 9. The connecting platform 84 is arranged in a ring shape on the upper end face of the air-concentrating part 81. This arrangement allows the connecting platform 84 to engage with the locking platform 93 on the bracket 9 from any position, eliminating the need to select a specific position for engagement between the bracket 9 and the air-concentrating hood 8, thus improving installation convenience.

[0138] refer to Figure 16 and 17 As shown, the support portion 82 includes a vertical portion 823 and an inclined portion 824. One end of the vertical portion 823 is connected to the inner ring of the air-gathering portion 81, and the other end of the vertical portion 823 is connected to one end of the inclined portion 824. The other end of the inclined portion 824 is connected to one end of the surrounding portion 83. The inner diameter of the vertical portion 823 remains unchanged along the axial direction, and the inner diameter of the inclined portion 824 gradually decreases from the end connected to the vertical portion 823 to the end connected to the surrounding portion 83.

[0139] The plane of the enclosure 83 is perpendicular to the axis of the wind-concentrating shroud 8. This arrangement ensures that after the heating device is assembled with the wind-concentrating shroud 8, the frame 41 of the electrode sheath 4 located at the lower end of the heat conductor 2 on the heating device can be supported by the enclosure 83, thereby firmly installing the heating device on the wind-concentrating shroud 8 and axially limiting the installation of the heating device to prevent it from moving.

[0140] Along the axial direction, the axial cross-sectional profile of the air-gathering section 81 is an inclined straight line or arc set at an acute angle to the axis of the air-gathering shroud 8, and the thickness of the air-gathering section 81 is equal at all positions along the direction from the outer ring to the inner ring. This arrangement makes the air-gathering section 81 a conical structure, with the inner and outer rings of the air-gathering section 81 at different heights along the axial direction, and the angle between the axial cross-sectional profile of the air-gathering section 81 and the axis of the air-gathering shroud 8 being an acute angle. This allows the air-gathering section 81 to change the direction of the airflow entering the air-gathering shroud 8, causing the airflow to converge at the air outlet of the air-gathering section 81, and then enter the heating device in the support section 82 to exchange heat with the heat conductor 2, so that the heated airflow flows out from the inner ring of the surrounding section 83.

[0141] refer to Figure 17 , 19 As shown in Figure 20, a slot 821 is formed on the side wall of the support part 82, and a snap-fit ​​platform 8212 is provided in the snap-fit ​​slot 821. The snap-fit ​​platform 8212 extends protruding from the inner side of the side wall of the snap-fit ​​slot 821 toward the center of the wind-concentrating hood 8. The snap-fit ​​platform 8212 is used to snap with the snap-fit ​​arm 6163 in the elastic buckle 616 on the fixing frame 6. During assembly, the upper end face of the snap-fit ​​arm 6163 abuts against the lower end face of the snap-fit ​​platform 8212. A gap is provided between the snap-fit ​​platform 8212 and the bottom wall of the snap-fit ​​slot 821 for assembly with the snap-fit ​​arm 6163. The snap-fit ​​slot 821 protrudes from the side wall of the support part 82 toward the direction away from the center of the wind-concentrating hood 8, so that the protruding distance of the snap-fit ​​slot 821 is greater than the thickness of the side wall of the support part 82, and an assembly gap is formed between the protruding side wall 8211 of the snap-fit ​​slot 821 and the outer side wall of the support part 82. This assembly gap can be used to abut against the support plate 92 on the bracket 9 for limiting, so that the support plate 92 provides limiting support for the wind shroud 8.

[0142] The limiting groove 822 is elongated and extends from the connection point between the air-gathering part 81 and the support part 82 to the connection point between the support part 82 and the surrounding part 83. Two opposing inclined surfaces are formed at the connection point of the limiting groove 822. This design facilitates the smooth entry of the limiting post 615 in the heat-conducting device into the limiting groove 822 through its inclined surfaces during installation, reducing friction during installation. The limiting groove 822 protrudes from the side wall of the support part 82 away from the center of the air-gathering hood 8, forming a protrusion 8221 on the outer side wall of the support part 82. An assembly gap is formed between the protrusion 8221 and the outer side wall of the support part 82. This assembly gap allows for contact with the support plate 92 on the bracket 9 for limiting and supporting the air-gathering hood 8.

[0143] The connecting platform 84 is engaged with the locking platform 93 on the bracket 9. At the same time, the protrusion 8221 of the limiting groove 822 and the outer side wall of the support 82 form an assembly gap and abut against the support plate 92 on the bracket 9 for limiting. This allows the bracket 9 to limit the wind shroud 8 in both the upper and lower directions, so that the wind shroud 8 is securely engaged on the bracket 9.

[0144] refer to Figure 7 and 18As shown, in the assembly process of the heat exchange mechanism of this embodiment, the heat-conducting spring 1 is first installed in the mounting hole 21 of the heat-conducting body 2, and then the heating body 3 is inserted into the inner ring of the heat-conducting spring 1 to form a heating module. Further, electrodes 5 are installed in the upper electrode sheath and the lower electrode sheath, and the conductive ring 7 is placed on the heating body 3. Then, the upper electrode sheath and the lower electrode sheath are installed on the upper and lower end faces of the heating module. The upper electrode sheath and the lower electrode sheath are fixed by the fixing bracket 6. At the same time, the heating module is fixed between the upper electrode sheath and the lower electrode sheath to form a heating device. Finally, the heating device is installed in the wind-concentrating shroud 8, and the wind-concentrating shroud 8, the bracket 9 and the protective net 10 are assembled together to form a heat exchange mechanism. The heat exchange mechanism gathers airflow into the heating module through the air-concentrating shroud 8, and then energizes the electrode 5 to heat the heating module. The heating module increases its contact area with the air through the heat conductor 2 for sufficient heat exchange. The heat-conducting spring 1 is installed in the buffer zone between the heating block mounting hole 21 and the heating element 3, which can better transfer the heat from the heating element 3 to the heat conductor 2, thus maximizing the heat exchange between the heat conductor 2 and the air. The heating element 3 is a ceramic graphene heating module containing graphene, which gives the heating element 3 good heating and heat transfer effects, as well as good thermal stability. This ensures that the heat output of the heating element 3 remains very stable during long-term use, maximizing the transfer of heat to the heat conductor 2. During the assembly process, the second contact part 123 of the heat-conducting spring 1 is subjected to external force, and at the same time, the first contact part 121 is displaced to the outside of the contact edge 12 through the transition part 122, so that the contact edge 12 can produce elastic deformation. This allows the heat-conducting spring 1 to adapt to the heating element 3 and the heat conductor 2, which have different dimensions due to processing issues.
