Description

Technical Field

[0001] The present invention relates to the technical field of heating devices, and in particular to a heating device using a ceramic graphene heating element. Background Art

[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 the heating equipment to achieve the best heating effect has become the research and development focus of various heating equipment on the market. In heating equipment, heating the heating element by heating electrodes to generate heat, and then convection with the air to complete the heating of the airflow is also 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. It is impossible to conduct electricity and heat multiple areas at the same time. If multiple heating elements are to be heated, multiple independent electrode rings need to be set up, which is complicated to assemble and requires multiple fixing parts in the subsequent assembly process. In addition, the fixing parts for fixing the electrodes in existing heating equipment are relatively simple and cannot guarantee the overall protection and fixation of the electrodes. In addition, due to the unstable fixation of the electrodes during use and transportation, the electrodes are prone to shaking up and down and circumferentially, resulting in poor contact.

[0003] At the same time, in the existing heating modules, the heating element and the heat conductor are generally connected by direct fixing or plugging, and there is no thermal spring structure between the heating element and the heat conductor that can produce elastic deformation when subjected to force. In addition, due to errors in the production process of the heating element and the heat conductor, resulting in dimensional inconsistency, it is easy to encounter installation difficulties when the heating element and the heat conductor are directly assembled later. At the same time, the ceramic heating module used in the existing heating device is relatively brittle and easy to break, and may be deformed by heat. If the heating element and the heat conductor are directly assembled and contacted, the problem of the heat conductor being deformed by heat and causing the heating element to break will also occur. At the same time, direct contact between the heating element and the heat conductor during assembly or transportation will also cause the heating element or the heat conductor to break.

[0004] In response to the above needs, it is necessary to propose a heating device that can increase the contact area between the heating element and the heat conductor, reduce thermal resistance, increase the contact area with the air for sufficient heat exchange, flexibly increase the number of heating elements, protect the electrodes from leakage, and enable the electrodes to be energized in multiple areas at the same time. Summary of the Invention

[0005] In order to solve at least one of the problems existing in the above-mentioned prior art, according to one aspect of the present invention, a heating device is provided, which increases the contact area between the heat conductor and the air to fully exchange heat. According to actual needs, a suitable number of heating elements are selected and installed on the heat conductor. The 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 so that the contact area between the heat conductor and the air can fully exchange heat. At the same time, a number of mounting rings are set on the electrode sheath that fixes the heat conductor and the heating element. The electrode ring on the electrode is accurately assembled in the mounting groove of the mounting ring, so that the electrode can be powered and work in multiple positions, and the electrode sheath can prevent leakage during the operation of the electrode, thereby ensuring the safety of the entire electrode assembly during operation.

[0006] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is as follows:

[0007] A heating device, comprising:

[0008] An electrode sheath, the electrode sheath comprising a frame, a plurality of mounting rings, and a plurality of connecting portions, wherein the mounting rings are arranged on the frame through the connecting portions, one end of each connecting portion is connected to the frame, and an extension line extending from the other end of each connecting portion passes through the center of the electrode sheath, at least one mounting ring is arranged on each connecting portion, a mounting groove is arranged on the mounting ring, and a mounting buckle is provided on the frame;

[0009] Electrode, the electrode includes a plurality of electrode rings and a plurality of connecting rods, the electrode rings are connected by the connecting rods, each connection is connected to at least one electrode ring, and the extension line of the connecting rod passes through the center of the electrode; the electrode rings are installed in the corresponding installation grooves;

[0010] A heating module, the heating module comprising a heat conductor and a heating element placed in a mounting hole of the heat conductor;

[0011] The fixing frame includes a fixing frame body, a buckle groove is provided on the outer side wall of the fixing frame body, a support seat and an undercut are provided on the inner side wall of the fixing frame body, the support seat and the undercut are respectively provided near two end faces of the fixing frame body in the height direction, and the mounting buckle is buckled with the buckle groove on the outer side wall of the fixing frame body to assemble the fixing frame and the electrode shield together;

[0012] The heating module is placed between an upper electrode sheath arranged above the fixing frame body and a lower electrode sheath arranged below the fixing frame body. The electrodes are energized to heat the heating element in the heating module.

[0013] Preferably, the heating module includes:

[0014] A heat conductor, wherein a plurality of mounting holes are provided on the heat conductor;

[0015] Heating element, a plurality of heating elements are provided, and the heating elements are placed in the mounting holes;

[0016] The thermally conductive spring comprises a bending edge and a contact edge, the contact edge is extended from the circumferential edge of the bending edge in a direction away from the bending edge, and an angle is formed between the contact edge and the bending edge. The contact edge comprises 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. The extension surface of the first contact portion and the extension surface of the second contact portion are in different planes, and the contact edge can produce elastic deformation relative to the bending edge when subjected to force; the thermally conductive spring is installed between the mounting hole on the heat conductor and the heating element. With this arrangement, the heat conductor can be used to increase the contact area with the air for sufficient heat exchange. The heating element can be movably installed on the heat conductor, and the thermal spring is installed in the buffer zone between the heating block mounting hole and the heating element, which can achieve better transfer of heat from the heating element to the heat conductor so that the contact area between the heat conductor and the air can be fully exchanged with heat. At the same time, the thermal spring can avoid the problem of poor contact caused by inconsistent sizes when the heat conductor and the heating element are directly assembled, thereby reducing thermal resistance and improving thermal conductivity. At the same time, the thermal spring can also prevent the unreasonable gap between the heat conductor and the heating element, causing the heating element to rupture during production or transportation, or the heat conductor to deform due to heat, causing the heating element to rupture.

[0017] Preferably, a conductive ring is arranged between the electrode ring and the heating element, one side of the conductive ring contacts the electrode ring, and the other side of the conductive ring contacts the end face of the heating element. The two upper and lower end faces of each heating element are in contact with a conductive ring. When the electrode ring is energized, the conductive ring heats the heating element, and the heating element transfers heat to the heat conductor through the thermal spring.

[0018] 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, the bottom wall of the bent edge contacts the upper end face of the heat conductor, and the contact edge is sleeved on the heating element so that the inner side wall of the second contact portion contacts the outer side wall of the heating element, and after the bottom wall of the bent edge contacts the upper end face of the heat conductor, the bent edge overlaps the heat conductor, and 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 in the same plane, when the contact edge contacts the heating element during assembly, the heating element squeezes the second contact portion so that the second contact portion is displaced outward, and the first contact portion is driven to displace outward through the transition portion, so that the outer side wall of the first contact portion can be squeezed against the heat conductor, thereby increasing the contact area and reducing thermal resistance. When the thermally conductive spring is assembled with the heat conductor and the heating element, the first contact portion cooperates with the transition portion and the second contact portion to enable the contact edge to produce elastic deformation, thereby preventing the thermally conductive spring from being unable to be assembled between the heating element and the heat conductor when there is a size deviation between the heating element and the heat conductor due to processing problems.

[0019] Preferably, the heating element is a ceramic graphene heating module containing graphene, and the centers of the mounting holes on the heat conductor are distributed on concentric circles with the center of the heat conductor as the center.

[0020] Preferably, the thickness of the heat conductor in the axial direction is smaller than the thickness of the heating element in the axial direction. This arrangement makes one end face of the heating element higher than the end face of the heat conductor on the same side, thereby forming a height difference between the end faces of the heating element and the heat conductor on the same side, and further forming a mounting area between the heating element and the heat conductor. This is to facilitate the subsequent installation of the electrode sheath to provide a mounting position for the electrode sheath, so that the connecting portion on the electrode sheath can be clamped in the mounting area formed by the height difference between the heat conductor and the heating element.

[0021] Preferably, the contact edge includes a plurality of spaced-apart unit contact portions, with a spacer area provided between each two 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.

[0022] Preferably, the width and height of each unit contact portion are equal, so as to ensure the uniformity of the heat conduction process of the unit contact portion, so that the heat conduction effect of any position of the contact portion is consistent. At the same time, the unit contact portion is provided to ensure that the external force received by the contact portion when in contact with the heat conductor and the heating element is transmitted to each unit contact portion, dispersing the external pressure received by the contact edge. At the same time, the unit contact portion will not be affected by other unit contact portions when elastically deformed by force, that is, multiple unit contact portions will not affect each other when subjected to force, so that the unit contact portions can all be in close contact with the respective contacting parts. If the contact edge is not provided with a spacing area, the elastic deformation of each area of ​​the contact edge will inevitably affect each other, thereby causing the contact edge of some areas to be unable to be in close contact with the heating element and the heat conductor, resulting in poor contact and the problem of large thermal resistance.

[0023] Preferably, a central mounting ring is provided at the center of the electrode sheath, and several connecting parts are connected together at one end close to the center of the electrode sheath through the central mounting ring, and at least one circumferential mounting ring is provided on each connecting part, and the centers of the circumferentially 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 close to the center of the electrode through the central electrode ring, and at least one circumferential electrode ring is provided on each connecting rod, and the centers of the circumferentially adjacent circumferential electrode rings are distributed on concentric circles with the center of the electrode as the center.

[0024] Preferably, the skeleton is a ring structure, one end of the connecting portion is connected to the inner circle of the skeleton, and the extension line of the other end of each connecting portion passes through the center of the skeleton.

[0025] 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 portion is connected to the outer wall of the annular step. This arrangement allows the annular step on the mounting ring to protect and limit the electrode ring on the electrode, thereby preventing the electrode ring and the electrode from moving in series. At the same time, it can also limit the conductive ring and the heating element between the two electrode rings, and the thermally conductive spring between the heating element and the heat conductor, to prevent them from moving up and down.

[0026] Preferably, an assembly groove for placing the electrode connecting rod is provided on the connecting portion. This arrangement allows the connecting rod on the electrode to be firmly placed in the connecting portion of the electrode sheath, thereby ensuring that the electrode sheath protects the connecting rod and preventing deformation caused by shaking of the electrode connecting rod during movement of the electrode assembly.

[0027] Preferably, a ridge is provided on the portion of the connection portion that connects to the outer wall of the outermost mounting ring, facing away from the center of the electrode sheath. The ridge extends toward the frame. The ridge and the mounting groove are located on the same side of the electrode sheath, and the height of the ridge is less than or equal to the height of the annular step. The ridge extends to the edge of the frame. This arrangement enhances the strength of the connection portion and ensures that the electrode sheath will not break during use and transportation.

[0028] Preferably, the undercut is disposed near the upper end surface of the fixing frame body, the support seat is disposed near the lower end surface of the fixing frame body, and a plurality of undercuts and support seats are disposed on the same circle along the circumference of the fixing frame body. This arrangement allows the heat conductor to be placed between the undercut and the support seat when it is installed, with the lower end surface of the undercut abutting against the upper end surface of the heat conductor, and the upper end surface of the support seat abutting against the lower end surface of the heat conductor, thereby enabling the support seat to stably support the heat conductor.

[0029] Preferably, an internal limiting strip is further provided on the inner side wall of the fixing frame body, and the internal limiting strip extends from the center of the fixing frame body in the height direction toward both ends of the fixing frame body.

[0030] Preferably, the internal limit strip is a long strip structure, and the upper end face of the internal limit strip is an inclined surface, which is inclined from the position where the internal limit strip is connected to the inner side wall of the fixing frame body toward the lower end face of the fixing frame body, and the angle between the inclined surface and the inner side wall of the fixing frame body located at the upper end of the internal limit strip is an obtuse angle. After the thermal conductor is assembled with the electrode sheath fixing assembly, the internal limit strip on the fixing frame abuts against the outer side wall of the thermal conductor or engages with the limiting opening on the outer side wall, so that the internal limit strip plays a role in preventing the thermal conductor from moving. At the same time, the upper end face of the internal limit strip is set as an inclined surface to ensure that the inclined surface can guide the assembly of the thermal conductor during the assembly of the thermal conductor with the fixing frame, and prevent the upper end face of the internal limit strip from obstructing the installation of the thermal conductor when it is flat, thereby ensuring smoothness during the installation process.

[0031] Preferably, an elastic buckle and a limiting column are further provided on the outer wall of the fixing frame body. The elastic buckle and the limiting column are respectively used to engage with the engaging groove and the limiting hole on the inner wall of the wind scoop. The elastic buckle includes a connecting arm connected to the outer wall of the fixing frame body, and a U-shaped elastic portion connected to one end of the connecting arm. One end of the U-shaped elastic portion is a connecting arm extending away from the outer wall of the fixing frame body, and the connecting arm is arranged perpendicularly or at an acute angle to the outer wall of the fixing frame body. The limiting column includes a limiting plate connected to the outer wall of the fixing frame body and limiting inclined plates placed on both sides of the limiting plate. The limiting inclined plates can ensure that when the limiting column is engaged with the positioning hole on the wind scoop, the inclined surface of the limiting inclined plate can play a guiding role, so that the limiting column can be smoothly assembled with the positioning hole.

[0032] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0033] 1. The heating module in the present invention increases the contact area with the air by the heat conductor to fully exchange heat. According to actual needs, a suitable number of heating elements are selected and installed on the heat conductor. The 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 so that the contact area between the heat conductor and the air can fully exchange heat. The heating element is a ceramic graphene heating module containing graphene, so that the heating element has good heating and heat transfer effects, and good thermal stability, so that the thermal power of the heating element is very stable during long-term use, and the heat is transferred to the heat conductor to the maximum extent. During the assembly process of the heat-conducting spring, the second contact part is subjected to external force, and at the same time, the first contact part is driven to move toward the outside of the contact edge through the transition part, so that the contact edge can produce elastic deformation, so that the heat-conducting spring can adapt to heating elements and heat conductors with different sizes due to processing problems.

[0034] 2. The present invention provides a buckle groove on the outer wall of the fixing frame body and a support seat and undercut on the inner wall of the fixing frame body, so that the fixing frame can be clamped with the electrode sheath on the outside and can clamp and support the heat conductor on the inside, ensuring that the electrode and the heat conductor connected to the electrode are prevented from moving while protecting the electrode. By installing the fixing frame between the upper and lower electrode sheaths, the heat conductor and electrode are firmly installed in the space enclosed by the fixing frame and the electrode sheath, and the movement of the electrode, the heat conductor, and the heating element can be prevented.

[0035] 3. The electrode assembly of the present invention provides a mounting ring on the electrode sheath, so that the electrode ring on the electrode is accurately assembled in the mounting groove of the mounting ring, and at the same time, the electrode can be energized and work at multiple positions. The electrode sheath can prevent leakage during the operation of the electrode, thereby ensuring the safety of the entire electrode assembly during operation.

[0036] 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 the heating element between the two electrode rings, and the thermally conductive spring between the heating element and the heat conductor to prevent them from moving up and down.

[0037] 5. In the present invention, the bottom wall of the safety ring on the electrode sheath is an annular bottom wall, and a through hole is provided on the annular bottom wall. The inner diameter of the through hole is less than or equal to the inner diameter of the electrode ring, and the outer diameter of the annular bottom wall is greater than or equal to the outer diameter of the electrode ring. This arrangement can ensure that after the electrode ring is placed in the mounting groove, the bottom wall of the mounting ring can cover the electrode ring, thereby preventing the electrode ring from contacting external components and thus leaking electricity.

Each connecting portion 42 is provided with at least one mounting ring 43, and a mounting groove 433 is provided on the mounting ring 43. The frame 41 is provided with a mounting buckle 411.

[0065] The electrode 5 includes several electrode rings 51 and several connecting rods 52. The electrode rings 51 are connected by connecting rods 52. Each connection is connected to at least one electrode ring 51. The extension lines of the connecting rods 52 pass through the center of the electrode 5.

The mounting buckle 411 is buckled with the buckle groove 611 on the outer wall of the fixing frame body 61 to assemble the fixing frame 6 and the electrode sheath 4 together. A plurality of support seats 613 and undercut 612 are provided, and the plurality of support seats 613 and the plurality of undercut 612 are evenly spaced. This arrangement ensures that the undercut 612 can be clamped to the heat conductor 2 at multiple positions, and the support seat 613 can also support the heat conductor 2 at multiple positions.

[0068] The support seat 613 and the undercut 612 are staggered, that is, the support seat 613 and the undercut 612 are arranged on different vertical lines perpendicular to the cross section of the fixing frame body 61 along the height direction of the fixing frame 6. This arrangement can ensure that the support seat 613 and the undercut 612 are staggered, thereby increasing the number of contact points between the fixing frame 6 and the heat conductor 2 along the circumferential direction, ensuring that the support seat 613 and the undercut 612 are clamped and supported on the heat conductor 2.

[0069] The heating module is placed between an upper electrode sheath disposed above the fixing frame body 61 and a lower electrode sheath disposed below the fixing frame body 61. The upper and lower electrode rings 51 installed in the upper and lower electrode sheaths are connected to the neutral and live wires, respectively, thereby energizing the electrodes 5 to heat the heating element 3 in the heating module. The mounting buckles 411 on the upper electrode sheath engage with the upper buckle grooves, while the mounting buckles 411 on the lower electrode sheath engage with the lower buckle grooves, thereby firmly securing the fixing frame 6 between the upper and lower electrode sheaths 4.

With this arrangement, the heat conductor 2 can be used to increase the contact area with the air for sufficient heat exchange. The heating element 3 can be movably installed on the heat conductor 2, and the thermal spring 1 is installed in the buffer zone between the heating block mounting hole 21 and the heating element 3, which can achieve better transfer of heat from the heating element 3 to the heat conductor 2 so that the contact area between the heat conductor 2 and the air can be fully exchanged with heat. At the same time, the thermal spring 1 can avoid the problem of poor contact caused by inconsistent sizes when the heat conductor 2 and the heating element 3 are directly assembled, thereby reducing thermal resistance and improving thermal conductivity. At the same time, the thermal spring 1 can also prevent the unreasonable gap between the heat conductor 2 and the heating element 3, causing the heating element 3 to rupture during production or transportation, or the heat conductor 2 to deform due to heat, causing the heating element 3 to rupture.

One side of the conductive ring 7 contacts the electrode ring 51, and the other side of the conductive ring 7 contacts the end face of the heating element 3. The two 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, the conductive ring 7 heats the heating element 3, and the heating element 3 transfers heat to the heat conductor 2 through the thermal spring 1.

[0072] The electrode sheath 4 is also provided with a mounting portion 423, which is arranged on the side of the connecting portion 42 between the central mounting ring 431 and the circumferential mounting ring 432. The mounting portion 423 is provided with a mounting opening, which is used to match the assembly hole on the thermal conductor 2. A fixing member is passed through the mounting opening and the assembly hole to further fix the thermal conductor 2 between the two electrode sheaths 4. The mounting portion includes a bottom wall and two side walls, both of which are connected to the connecting portion 42. The side wall extends along the side opposite the mounting groove 433, and the side wall extends toward the front of the electrode sheath 4. The bottom wall is provided with a mounting opening. The two side walls can enhance the strength of the mounting portion, ensuring sufficient strength and stability during installation and use.

[0073] The contact edge 12 of the thermally conductive spring 1 is inserted into the mounting hole 21 of the thermal conductor 2, and the contact edge 12 of the thermally conductive spring 1 is inserted between the thermal conductor 2 and the heating element 3. The outer wall of the first contact portion 121 contacts the inner wall of the mounting hole 21 on the thermal conductor 2, and the bottom wall of the bent edge 11 contacts the upper end surface of the thermal 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 portion 123 contacts the outer wall of the heating element 3. After the bottom wall of the bent edge 11 contacts the upper end surface of the thermal conductor 2, the bent edge 11 overlaps the thermal conductor 2, and the top wall of the bent edge 11 contacts the end surface of the electrode 5 groove, so that the bent edge 11 is fixed between the electrode ring 51 and the thermal conductor 2 to prevent the thermally conductive spring 1 from moving up and down. Because the bent edge 11 and the contact edge 12 are not in the same plane, when the contact edge 12 contacts the heating element 3 during assembly, the heating element 3 squeezes the second contact portion 123, causing the second contact portion 123 to displace outward. This, in turn, drives the first contact portion 121 outward via the transition portion 122, allowing the outer wall of the first contact portion 121 to squeeze against the heat conductor 2, thereby increasing the contact area and reducing thermal resistance. When the thermally conductive spring 1 is assembled with the heat conductor 2 and the heating element 3, the first contact portion 121 cooperates with the transition portion 122 and the second contact portion 123 to allow the contact edge 12 to undergo elastic deformation, preventing the thermally conductive spring 1 from being unable to be assembled between the heating element 3 and the heat conductor 2 due to dimensional deviations caused by processing problems.

[0074] refer to Figure 7 As shown, the heat conductor 2 is provided with a plurality of heat exchange holes, which extend along the axial direction of the heat conductor 2. The heat conductor 2 has a honeycomb structure. The heat exchange holes are evenly arranged to form a honeycomb mesh on the heat conductor 2. The heat exchange holes can increase the contact area with the air and thus effectively exchange heat.

[0075] refer to Figure 8 As shown, the heating element 3 is a ceramic graphene heating module containing graphene. The heating element 3 is also provided with a plurality of heating holes 31, which extend along the axial direction of the heating element 3. The heating element 3 has a honeycomb structure, and the surface of the heating element 3 and the inner wall of the heating holes 31 both contain graphene, which makes the heating element 3 have good heating and heat transfer effects, and good thermal stability. This ensures that the thermal power of the heating element 3 is very stable during long-term use, and maximizes the heat transfer to the heat conductor 2.

[0076] The centers of the mounting holes 21 on the heat conductor 2 are all distributed on concentric circles with the center of the heat conductor 2 as the center. 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 set 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. The centers of the circumferential mounting holes 212 in the same layer of circumferential mounting holes 212 are equidistant from the center of the heat conductor 2. This arrangement allows the heating element 3 to be movably set at the center position of the heat conductor 2 and at circumferential positions at a certain distance from the center, so that the heating element 3 can evenly transfer heat to the central area of ​​the heat conductor 2 and various areas in the radial direction.

[0077] In this embodiment, the cross-sectional shape of the heat conductor 2 is circular, and seven mounting holes 21 are provided on the heat conductor 2, including a central mounting hole 211 provided at the center of the heat conductor 2 and six circumferential mounting holes 212 provided 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 centers of the six mounting holes 21 and the center of the heat conductor 2 is half the radius of the heat conductor 2.

[0078] The number of the heating elements 3 is less than or equal to the number of the mounting holes 21 on the heat conductor 2 . The number of the heating elements 3 can be flexibly set according to actual needs to improve applicability when increasing or decreasing the number of the heating elements 3 .

[0079] The thickness of the heat conductor 2 along the axial direction is smaller 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, thereby forming a height difference between the end faces of the heating element 3 and the heat conductor 2 on the same side, and further forming a mounting area between the heating element 3 and the heat conductor 2. This is to facilitate the subsequent installation of the electrode sheath to provide a mounting position for the electrode sheath, so that the connecting portion on the electrode sheath can be clamped in the mounting area formed by the height difference between the heat conductor 2 and the heating element 3.

[0080] The heat transfer holes 22 on the heat conductor 2 are hexagonal holes. The hexagonal holes can ensure sufficient heat exchange area while also enhancing the structural strength of the heat conductor 2 and preventing the heat conductor 2 from being damaged or deformed during use and transportation.

[0081] refer to Figure 5As shown, the thermally conductive spring 1 is a heat-conducting metal material that can be elastically deformed. In this embodiment, preferably, the thermally conductive spring 1 is an aluminum-based material, a copper-based material or an iron-based material. The first contact portion 121, the transition portion 122, and the second contact portion 123 on the thermally conductive spring 1 are all straight plate structures. The extension surface of the first contact portion 121 and the extension surface of the second contact portion 123 are arranged parallel to each other, and the first contact portion 121 and the second contact portion 123 can both be tightly attached to the components they are in contact with when subjected to external force. The transition portion 122 is arranged at an angle 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 a, and the range of a is 0°<a≤30°, that is, the angle at which the transition portion 122 is bent relative to the first contact portion 121 is a. The angle between the transition portion 122 and the extended surface of the second contact portion 123 is b, and the range of b is 0°<b≤30°, that is, the angle at which the transition portion 122 is bent relative to the second contact portion 123 is b.

[0082] The connection between the bent edge 11 and the first contact portion 121 is an arc transition. This arrangement prevents stress concentration from occurring between the bent edge 11 and the contact edge 12, and ensures that when the contact edge 12 is elastically deformed under the action of an external force, the connection between the bent edge 11 and the contact edge 12 will not easily break due to stress concentration. The bent edge 11 and the first contact portion 121 are arranged at a right angle. This arrangement facilitates the insertion of the heat-conducting spring 1 into the mounting hole 21 of the heat conductor 2, so that the bent edge 11 can fit tightly against the upper end face of the heat conductor 2, while also allowing the first contact portion 121 to fit tightly against the heat conductor 2. It also ensures that when the contact edge 12 is subjected to an external force, the entire side surfaces of the first contact portion 121 and the second contact portion 123 are in close contact with the respective contacting components, thereby ensuring the tightness of the contact edge 12.

[0083] The contact edge 12 includes a plurality of spaced-apart unit contact portions, with a spacer 124 disposed between each adjacent unit contact portion. 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 spacer 124 extends from the edge of the bent edge 11 to the bottom of the contact edge 12.

[0084] The width and height of each unit contact part are equal, which can ensure the uniformity of the heat conduction process of the unit contact part, so that the heat conduction effect of any position of the contact part is consistent. At the same time, the unit contact part can ensure that the external force received by the contact part when in contact with the heat conductor 2 and the heating element 3 is transmitted to each unit contact part, dispersing the external pressure received by the contact edge 12. At the same time, the unit contact part will not be affected by other unit contact parts when it is elastically deformed under force, that is, multiple unit contact parts will not affect each other when under force, so that the unit contact parts can all be in close contact with the components they are in contact with. If the contact edge 12 is not provided with a spacing area 124, the elastic deformation of each area of ​​the contact edge 12 will inevitably affect each other, and then cause the contact edge 12 in some areas to be unable to be in close contact with the heating element 3 and the heat conductor 2, resulting in poor contact and the problem of high thermal resistance. The spacing of the spacing areas 124 is equal along the circumference, or gradually increases, or gradually decreases, or is irregularly distributed. In this embodiment, preferably, the spacing of the spacing areas 124 is equal.

[0085] The bending edge 11 is an annular member, and the contact edge 12 extends from the inner edge of the bending edge 11 in a direction away from the bending edge 11. The bending edge 11 is designed according to the heating element 3 and the heat conductor 2 used with it. The cross-sectional shape of the bending edge 11 can be triangular, circular, or polygonal. In this embodiment, the cross-section of the bending edge 11 is preferably circular, that is, the projection of the bending edge 11 in the axial direction is a circular ring.

[0086] A notch area 111 is provided on the bending edge 11, and the bending edge 11 forms two oppositely disposed ends of the bending edge 11 in the notch area 111. With this arrangement, the notch area 111 breaks the bending edge 11 into an unclosed structure, thereby enabling the bending edge 11 to also have circumferential elastic deformation capabilities. With this arrangement, the notch area 111 can cooperate with the spacer area 124 to adapt to the heating element 3 and the heat conductor 2 with slightly different sizes. In particular, the setting of the notch area 111 can enable the bending edge 11 to have sufficient deformation capabilities when assembled between the heating element 3 and the heat conductor 2, thereby avoiding the problem of poor contact during the installation process leading to high thermal resistance. When the bending edge 11 is a fully enclosed annular structure, the bending edge 11 cannot produce elastic deformation, thereby preventing the thermally conductive spring 1 from being adapted to be assembled on the heating element 3 and the heat conductor 2 with inconsistent sizes due to production errors.

[0087] 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 spacer area 124. This arrangement forms an open structure in the notch area 111 from the bent edge 11 to the contact edge 12, ensuring that the bent edge 11 of the thermally conductive spring 1 can drive the contact edge 12 to undergo circumferential elastic deformation when it undergoes elastic deformation, thereby adapting to slightly different sizes of the heating element 3 and the heat conductor 2.

[0088] refer to Figure 9 As shown, the axial height of the connecting portion 42 on the electrode sheath 4 is less than or equal to the height of the mounting ring 43. This arrangement ensures that after the electrode sheath 4 is subsequently assembled with the heating element 3, the connecting portion 42 can be smoothly snapped into 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.

[0089] The electrode ring 51 is in a corrugated shape, so that the electrode ring 51 has elastic deformability, increases the adaptability of the installation gap, and prevents poor contact.

[0090] A central mounting ring 431 is provided at the center of the electrode sheath 4. Several connecting portions 42 are connected together at their ends near the center of the electrode sheath 4 via the central mounting ring 431. Each connecting portion 42 is provided with at least one circumferential mounting ring 432. The centers of adjacent circumferential mounting rings 432 are all distributed on concentric circles centered on the center of the electrode sheath 4. In other words, the circumferential mounting rings 432 on the same circle are equidistant from the central mounting ring 431.

[0091] refer to Figure 10 As shown, a central electrode ring 511 is provided at the center of the electrode 5, and several connecting rods 52 are connected together at one end near the center of the electrode 5 through the central electrode ring 511. Each connecting rod 52 is provided with at least one circumferential electrode ring 512, and the centers of the circumferentially adjacent circumferential electrode rings 512 are distributed on concentric circles with the center of the electrode 5 as the center. That is, the circumferential electrode rings 512 and the central electrode ring 511 located on the same circle are equidistant. This arrangement allows the electrode sheath 4 to be provided with a mounting ring 43 at both the central position and the circumferential position at a certain distance from the center, thereby allowing the electrode sheath 4 to adapt to the central electrode ring 511 and the circumferential electrode rings 512 on the electrode 5, ensuring that the electrode 5 assembly can complete the conductive work in both the central area and the circumferential area at a certain distance from the center.

[0092] In this embodiment, the mounting rings 43 are evenly spaced on the same circle with the center of the electrode sheath 4 as the center, and the angles between each two adjacent connecting parts 42 are equal. In this embodiment, 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 angle between each two connecting parts 42 is 60°, and the angle between the center of each two circumferential mounting rings 432 and the center of the electrode sheath 4 is 60°. Correspondingly, the electrode rings 51 are evenly spaced on the same circle with the center of the electrode 5 as the center, and the angles between each two adjacent connecting rods 52 are equal. The electrode rings 51 include a central electrode ring 511 and six circumferential electrode rings 512 with their centers on the same circle, the angle between each two connecting rods 52 is 60°, and the angle between the center of each two circumferential electrode rings 512 and the center of the electrode 5 is 60°. The circumferential mounting ring 432 divides the connecting portion 42 connected thereto into several sections. Since the mounting ring 43 includes a central mounting ring 431 and a circumferential mounting ring 432 is provided on each connecting portion 42, the circumferential mounting ring 432 on each connecting portion 42 divides the connecting portion 42 into two sections. The two sections of connecting portions 42 are respectively located on two symmetrical sides of the circumferential mounting ring 432. The two ends of one section of the connecting portion 42 are respectively connected to the outer wall of the central mounting ring 431 and the outer wall of the circumferential mounting ring 432. One end of the other section 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.

[0093] The circumferential mounting ring 432 divides the connecting portion 42 connected thereto into several segments, and the extension line of one segment of the connecting portion 42 connected to the skeleton 41 can pass through the center of the electrode sheath 4, that is, the connecting portions 42 divided into several segments are all on the same straight line.

[0094] The skeleton 41 is an annular structure, with one end of each connecting portion 42 connected to the inner ring of the skeleton 41, and the extension line of the other end of each connecting portion 42 passes through the center of the skeleton 41. Preferably, the skeleton 41 is an annular structure, so that any point on the skeleton 41 is at an equal distance from the center of the electrode sheath 4, thereby ensuring the consistency of the length of each connecting portion 42 and allowing the connecting portions 42 to cooperate with the skeleton 41 to enhance the overall strength of the electrode sheath 4.

[0095] 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. The connecting portion 42 is connected to the outer wall of the annular step 4332. The bottom wall is an annular bottom wall 4331, which is provided with a through hole. 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 when 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 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 a tangential manner. It also limits the conductive ring 7 and the heating element 3 between the two electrode rings 51, and the thermally conductive spring 1 between the heating element 3 and the heat conductor 2, to prevent them from moving up and down.

[0096] The connecting portion 42 is provided with an assembly groove 421 for accommodating the connecting rod 52 of the electrode 5. This arrangement allows the connecting rod 52 on the electrode 5 to be securely placed in the connecting portion 42 of the electrode sheath 4, thereby ensuring that the electrode sheath 4 protects the connecting rod 52 and preventing deformation of the electrode 5 assembly due to shaking of the connecting rod 52 of the electrode 5 during movement.

[0097] The assembly groove 421 on the connecting portion 42 is connected to the mounting groove 433. The position where the assembly groove 421 and the mounting groove 433 are connected is located at the position where the connecting portion 42 and the electrode ring 51 are connected. This arrangement allows the connecting rod 52 connected to the electrode ring 51 to be smoothly placed in the assembly groove 421.

[0098] A ridge 422 is provided on the portion of the connecting portion 42 that connects to the outer wall of the outermost mounting ring 43, facing away from the center of the electrode sheath 4. The ridge 422 extends toward the frame 41. The ridge 422 and the mounting groove 433 are located on the same side of the electrode sheath 4. The height of the ridge 422 is less than or equal to the height of the annular step 4332. The ridge 422 extends to the edge of the frame 41, which enhances the strength of the connecting portion 42 and prevents breakage of the electrode sheath 4 during use and transportation.

[0099] 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 process 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 buckled.

[0100] refer to Figure 12As shown, the support base 613 and undercut 612 on the mounting bracket 6 have different shapes. This arrangement facilitates distinguishing the upper and lower positions of the mounting bracket during installation, thereby improving the positioning and assembly of the upper and lower electrode sheaths 4. The upper end surface of the undercut 612 is inclined. This arrangement ensures that when the heat conductor 2 is assembled with the mounting bracket 6, it can pass through the inclined surface of the undercut 612 and smoothly enter the bottom of the undercut 612, thereby securing the undercut 612 to the upper end surface of the heat conductor 2.

[0101] The fixing frame body 61 is an annular member. In this embodiment, the fixing body is preferably a circular ring member. This configuration allows the fixing frame 6 to have good elastic deformation ability, thereby better assembling with the electrode sheath 4 and being able to completely wrap the outer wall of the heat conductor 2.

[0102] The buckle grooves 611 include an upper buckle groove close to the upper end surface of the fixing frame body 61 and a lower buckle groove close to the lower end surface of the fixing frame body 61. The upper buckle grooves include several buckle grooves 611 on the same circle, and the lower buckle grooves include several buckle grooves 611 on the same circle.

[0103] The upper buckle groove and the lower buckle groove are arranged relative to each other or staggered. If the upper buckle groove and the lower buckle groove are arranged relative to each other, the upper buckle groove and the lower buckle groove are located on the same axial section. If the upper buckle groove and the lower buckle groove are staggered, the upper buckle groove and the lower buckle groove are located on different axial sections.

[0104] The upper buckle groove and the lower buckle groove are staggered. This arrangement prevents the mounting buckle 411 on the upper electrode sheath that is buckled with the upper buckle groove and the mounting buckle 411 on the lower electrode sheath that is buckled with the lower buckle groove from interfering with each other, preventing the mounting buckles 411 on the two electrode sheaths 4 from colliding, and ensuring that the mounting buckle 411 has sufficient length to be buckled with the buckle groove 611, while reducing the height of the fixing frame body 61, thereby reducing the size of the electrode sheath 4 fixing assembly, making the electrode sheath 4 fixing assembly more compact.

[0105] The undercuts 612 are disposed near the upper end surface of the fixing frame body 61, and the support seats 613 are disposed near the lower end surface of the fixing frame body 61. A plurality of undercuts 612 and support seats 613 are disposed on the same circle along the circumference of the fixing frame body 61. This arrangement allows the heat conductor 2 to be placed between the undercuts 612 and the support seats 613 when it is installed, with the lower end surface of the undercuts 612 abutting against the upper end surface of the heat conductor 2, and the upper end surface of the support seats 613 abutting against the lower end surface of the heat conductor 2, thereby enabling the support seats 613 to firmly support the heat conductor 2.

[0106] 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 height of the fixing frame body 61 toward both ends of the fixing frame body 61. The internal limiting strip 614 is an elongated strip, and the upper end surface of the internal limiting strip 614 is an inclined surface. The inclined surface is inclined from the point where the internal limiting strip 614 connects with the inner sidewall of the fixing frame body 61 toward 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 limit strip 614 on the fixing frame 6 abuts against the outer wall of the heat conductor 2 or engages with the limit opening on the outer wall, so that the internal limit strip 614 prevents the heat conductor 2 from moving. At the same time, the upper end face of the internal limit strip 614 is set as an inclined surface to ensure that the inclined surface can guide the assembly of the heat conductor 2 during the assembly of the heat conductor 2 with the fixing frame 6, and prevent the upper end face of the internal limit strip 614 from obstructing the installation of the heat conductor 2 when it is flat, thereby ensuring smoothness of the installation process.

[0107] An elastic buckle 616 and a limiting post 615 are also provided on the outer wall of the fixing frame body 61. The elastic buckle 616 and limiting post 615 are respectively configured to engage with the engaging groove and limiting hole on the inner wall of the wind scoop. The elastic buckle 616 includes a connecting arm 6161 connected to the outer wall of the fixing frame 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 frame body 61, and the connecting arm 6163 is arranged perpendicularly or at an acute angle to the outer wall of the fixing frame body 61. The limiting post 615 includes a limiting plate connected to the outer wall of the fixing frame body 61 and limiting inclined plates disposed on both sides of the limiting plate. The limiting inclined plates ensure that when the limiting post 615 engages the positioning hole on the wind scoop, the inclined surfaces of the limiting inclined plates serve as a guide, allowing the limiting post 615 to be smoothly assembled with the positioning hole.

[0108] The support seat 613 and the undercut 612 on the fixing frame body 61 are staggered, that is, the support seat 613 and the undercut 612 are arranged on different vertical lines perpendicular to the cross-section of the fixing frame body 61 along the height direction of the fixing frame 6. This arrangement can ensure that the support seat 613 and the undercut 612 are staggered, thereby increasing the number of contact points between the fixing frame 6 and the heat conductor 2 along the circumferential direction, ensuring that the support seat 613 and the undercut 612 are clamped and supported by the heat conductor 2.

[0109] The support base 613 and the undercut 612 have different shapes. This arrangement facilitates distinguishing the upper and lower positions of the mounting bracket during installation, thereby better positioning and assembling the upper and lower electrode sheaths 4. The upper end surface of the undercut 612 is inclined. This arrangement ensures that when the heat conductor 2 is assembled with the fixing bracket 6, the heat conductor 2 can pass through the inclined surface of the undercut 612 and smoothly enter the bottom of the undercut 612, thereby snapping the undercut 612 onto the upper end surface of the heat conductor 2.

[0110] The fixing frame body 61 is an annular member. In this embodiment, the fixing frame body is preferably a circular ring member. This configuration allows the fixing frame 6 to have good elastic deformation ability, thereby better assembling with the electrode sheath 4 and being able to completely wrap the outer wall of the heat conductor 2.

[0111] The buckle grooves 611 include an upper buckle groove close to the upper end surface of the fixing frame body 61 and a lower buckle groove close to the lower end surface of the fixing frame body 61. The upper buckle grooves include several buckle grooves 611 on the same circle, and the lower buckle grooves include several buckle grooves 611 on the same circle.

[0112] The upper buckle groove and the lower buckle groove are arranged relative to each other or staggered. If the upper buckle groove and the lower buckle groove are arranged relative to each other, the upper buckle groove and the lower buckle groove are located on the same axial section. If the upper buckle groove and the lower buckle groove are staggered, the upper buckle groove and the lower buckle groove are located on different axial sections.

[0113] The upper buckle groove and the lower buckle groove are staggered. This arrangement prevents the mounting buckle 411 on the upper electrode sheath that is buckled with the upper buckle groove and the mounting buckle 411 on the lower electrode sheath that is buckled with the lower buckle groove from interfering with each other, preventing the mounting buckles 411 on the two electrode sheaths 4 from colliding, and ensuring that the mounting buckle 411 has sufficient length to be buckled with the buckle groove 611, while reducing the height of the fixing frame body 61, thereby reducing the size of the electrode sheath 4 fixing assembly, making the electrode sheath 4 fixing assembly more compact.

[0114] The undercuts 612 are disposed near the upper end surface of the fixing frame body 61, and the support seats 613 are disposed near the lower end surface of the fixing frame body 61. A plurality of undercuts 612 and support seats 613 are disposed on the same circle along the circumference of the fixing frame body 61. This arrangement allows the heat conductor 2 to be placed between the undercuts 612 and the support seats 613 when it is installed, with the lower end surface of the undercuts 612 abutting against the upper end surface of the heat conductor 2, and the upper end surface of the support seats 613 abutting against the lower end surface of the heat conductor 2, thereby enabling the support seats 613 to firmly support the heat conductor 2.

[0115] 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 height of the fixing frame body 61 toward both ends of the fixing frame body 61. The internal limiting strip 614 is an elongated strip, and the upper end surface of the internal limiting strip 614 is an inclined surface. The inclined surface is inclined from the point where the internal limiting strip 614 connects with the inner sidewall of the fixing frame body 61 toward 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 limit strip 614 on the fixing frame 6 abuts against the outer wall of the heat conductor 2 or engages with the limit opening on the outer wall, so that the internal limit strip 614 prevents the heat conductor 2 from moving. At the same time, the upper end face of the internal limit strip 614 is set as an inclined surface to ensure that the inclined surface can guide the assembly of the heat conductor 2 during the assembly of the heat conductor 2 with the fixing frame 6, and prevent the upper end face of the internal limit strip 614 from obstructing the installation of the heat conductor 2 when it is flat, thereby ensuring smoothness of the installation process.

[0116] An elastic buckle 616 and a limiting post 615 are also provided on the outer wall of the fixing frame body 61. The elastic buckle 616 and limiting post 615 are respectively configured to engage with the engaging groove and limiting hole on the inner wall of the wind scoop. The elastic buckle 616 includes a connecting arm 6161 connected to the outer wall of the fixing frame 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 frame body 61, and the connecting arm 6163 is arranged perpendicularly or at an acute angle to the outer wall of the fixing frame body 61. The limiting post 615 includes a limiting plate connected to the outer wall of the fixing frame body 61 and limiting inclined plates disposed on both sides of the limiting plate. The limiting inclined plates ensure that when the limiting post 615 engages the positioning hole on the wind scoop, the inclined surfaces of the limiting inclined plates serve as a guide, allowing the limiting post 615 to be smoothly assembled with the positioning hole.
