Description

Technical Field

[0001] This invention relates to the field of heating electrode technology, and more particularly to an electrode assembly. 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 complete the heating of the airflow, is a commonly used heating method. However, the heating electrodes used in existing heating equipment are mostly independent electrode rings, with simple structure and limited heating effect. 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, which is complicated to assemble and requires multiple fixing parts in the subsequent assembly process. In addition, there is the problem of poor contact caused by electrode shaking during use and transportation. Moreover, most existing heating equipment has the electrodes directly exposed or partially exposed, without providing protection for the electrodes and leakage protection.

[0003] To address the above requirements, an electrode assembly is needed that can protect the electrode from leakage and enable the electrode to be energized simultaneously in multiple areas. Summary of the Invention

[0004] To address at least one problem existing in the prior art, according to one aspect of the present invention, an electrode assembly is provided. By providing a mounting ring on the electrode sheath, the electrode ring on the electrode is accurately assembled into the mounting groove of the mounting ring, enabling the electrode to be energized and operate at multiple positions. Furthermore, the electrode sheath can prevent leakage during electrode operation, thereby ensuring the safety of the entire electrode assembly during operation.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0006] An electrode assembly, comprising:

[0007] The 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, and 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, and the mounting ring is provided with a mounting groove.

[0008] 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.

[0009] This configuration ensures that the connecting part is positioned along the radial direction of the electrode sheath, and the corresponding connecting rod is also positioned along the radial direction of the electrode. This guarantees that the electrode ring on the electrode can be accurately assembled into the mounting groove of the mounting ring, while also allowing the electrode to be energized and operational in multiple positions. The electrode sheath also prevents leakage during electrode operation, thereby ensuring the safety of the entire electrode assembly during operation.

[0010] Preferably, a central mounting ring is provided at the center of the electrode sheath, and several connecting parts are connected together at their ends 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. That is, the circumferential mounting rings located on the same circle are equidistant from the central mounting ring.

[0011] Preferably, a central electrode ring is disposed at the center of the electrode, and several connecting rods are connected together at their ends near the center of the electrode via 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. That is, the circumferential electrode rings located on the same circle are equidistant from the central electrode ring.

[0012] This design allows mounting rings to be installed on the electrode sheath at both the center and a certain distance from the center, enabling the electrode sheath to fit the central and circumferential electrode rings on the electrode. This ensures that the electrode assembly can conduct electricity in both the central region and the circumferential region at a certain distance from the center.

[0013] More preferably, at least two circumferential central mounting rings are provided on each connection in the radial direction.

[0014] Preferably, the end of each connector away from the skeleton extends to the center of the electrode sheath, and one end of several connectors is connected at the center of the electrode sheath; the end of each connecting rod facing the center of the electrode extends to the center of the electrode, and one end of several connecting rods is connected at the center of the electrode.

[0015] This configuration ensures that the connection points of several connecting parts are located at the center of the electrode sheath, and the connection points of several connecting rods are located at the center of the electrode. This guarantees the uniformity of the distribution of the mounting rings on the connecting parts and the uniformity of the distribution of the electrode rings on the connecting rods. Both the mounting rings and the electrode rings are evenly distributed outward from the center of the electrode assembly with intervals, ensuring uniform conductivity.

[0016] 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.

[0017] As a better alternative, the skeleton is a circular ring structure, which ensures that any point on the skeleton is equidistant from the center of the electrode sheath, thereby guaranteeing the consistency of the length of each connection part, and at the same time, the connection parts work together with the skeleton to enhance the overall strength of the electrode sheath.

[0018] 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.

[0019] This design 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 the same direction. 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.

[0020] Preferably, the bottom wall is an annular bottom wall with a through hole. 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 ensures that after the electrode ring is placed in the mounting groove, the bottom wall of the mounting ring can cover the electrode ring, preventing the electrode ring from contacting external components and thus causing leakage.

[0021] Preferably, the circumferential mounting ring divides the connecting portion to which it is connected into several segments. If the mounting ring includes a central mounting ring and a circumferential mounting ring on each connecting portion, then the circumferential mounting ring on each connecting portion divides the connecting portion into two segments. These two connecting segments are located on opposite sides of the circumferential mounting ring. The two ends of one connecting segment are respectively connected to the outer wall of the central mounting ring and the outer wall of the circumferential mounting ring. One end of the other connecting segment is connected to the outer wall of the circumferential mounting ring, and the other end is connected to the frame.

[0022] Preferably, in another embodiment, the circumferential mounting ring divides the connecting portion connected to it into several segments, and the extension line of the connecting portion connected to the skeleton can pass through the center of the electrode sheath, that is, the connecting portions divided into several segments are all on the same straight line, or the extension line of the connecting portion connected to the skeleton deviates from the center of the electrode sheath, that is, the connecting portions divided into several segments are not on the same straight line, and only the connecting portion connected to the central mounting ring or whose end is located at the center of the electrode sheath passes through the center of the electrode sheath and the skeleton.

[0023] Preferably, the connecting part is provided with an assembly groove for placing the connecting rod of the electrode.

[0024] This design ensures that the connecting rod on the electrode is securely placed in the connecting part of the electrode sheath, thereby protecting the connecting rod from deformation caused by the shaking of the connecting rod during the movement of the electrode assembly.

[0025] Preferably, the assembly groove on the connecting part is connected to the mounting groove. Furthermore, the connection point between the assembly groove and the mounting groove is located at the connection point between the connecting part and the electrode ring. This arrangement allows the connecting rod connecting the electrode ring to be smoothly inserted into the assembly groove.

[0026] Preferably, the axial height of the connecting part is less than or equal to the height of the mounting ring. This setting ensures that after the electrode sheath is assembled with the heating element, the connecting part can be smoothly engaged in the mounting area formed by the height difference between the heating element and the heat conductor.

[0027] Preferably, the extension line of each connector passes through the center of the mounting ring to which it is connected, and the extension line of each connecting rod passes through the center of the electrode ring to which it is connected.

[0028] Preferably, a positioning strip extends from the outer wall of the electrode ring on the side opposite to the electrode center; a positioning groove is provided on the connecting part to mate with the positioning strip. The positioning strip is set on the outer wall of the outermost circumferential electrode ring opposite to the electrode center and extends in a direction away from the electrode center. The length of the positioning strip is less than or equal to the length of the positioning groove that it is adapted to install. This allows the electrode to be positioned and installed in the electrode sheath after the positioning strip and positioning groove are assembled, preventing incorrect electrode assembly position.

[0029] Preferably, a raised strip is provided on the part of the connecting portion that connects to the outer wall of the outermost mounting ring away from the center of the electrode sheath, and the raised strip extends in the direction toward the skeleton.

[0030] Preferably, the raised ridge and the mounting groove are located on the same side of the electrode sheath, and the height of the raised ridge is less than or equal to the height of the annular step. The raised ridge extends to the edge of the frame, which enhances the strength of the connection and ensures that the electrode sheath will not break during use and transportation.

[0031] Preferably, the mounting rings are evenly spaced on the same circle with the center of the electrode sheath as the center, and the included angle between each pair of adjacent connecting parts is equal.

[0032] Preferably, the electrode ring is corrugated. This design gives the electrode ring elastic deformation, increases the adaptability of installation gaps, and prevents poor contact.

[0033] Preferably, the frame is provided with a limiting step and a mounting buckle. The limiting step and mounting buckle are used to connect with the fixing frame for subsequent wrapping of the heat conductor. The mounting buckle is used to engage or snap into the buckle groove on the fixing frame, and the limiting step is used to abut against the end face of the fixing frame, which can enhance the strength of the frame. During the installation of the electrode sheath and the fixing frame, the limiting step applies pressure to the fixing frame, thereby supporting the frame and preventing local deformation when the electrode sheath and the fixing frame are fastened together.

[0034] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0035] 1. 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.

[0036] 2. 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.

[0037] 3. In this invention, the bottom wall of the safety ring on the electrode sheath is an annular bottom wall with a through hole. 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 design ensures that after the electrode ring is placed in the mounting groove, the bottom wall of the mounting ring can cover the electrode ring, preventing the electrode ring from contacting external components and thus causing leakage.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings.

[0050] Example 1

[0051] refer to Figure 1-2 As shown, an electrode assembly includes: an electrode sheath 1 and an electrode 2;

[0052] The electrode sheath 1 includes a skeleton 11, a plurality of mounting rings 13 and a plurality of connecting parts 12. The mounting rings 13 are disposed on the skeleton 11 through the connecting parts 12. One end of each connecting part 12 is connected to the skeleton 11. The extension line extending from the other end of each connecting part 12 passes through the center of the electrode sheath 1. At least one mounting ring 13 is provided on each connecting part 12. The mounting ring 13 is provided with a mounting groove 133. The mounting groove 133 is provided on the back side of the electrode sheath 1.

[0053] Electrode 2 includes several electrode rings 21 and several connecting rods 22. The electrode rings 21 are connected by the connecting rods 22, and each connection is connected to at least one electrode ring 21. The extension lines of the connecting rods 22 all pass through the center of electrode 2. The electrode rings 21 are installed in corresponding mounting slots 133. This arrangement ensures that the connecting part 12 is arranged along the radial direction of the electrode sleeve 1, and the corresponding connecting rods 22 are also arranged along the radial direction of the electrode 2. This ensures that the electrode rings 21 on electrode 2 can be accurately assembled in the mounting slots 133 of the mounting ring 13. At the same time, it allows electrode 2 to be energized and work in multiple positions. Electrode sleeve 1 can prevent leakage during the operation of electrode 2, thereby ensuring the safety of the entire electrode assembly during operation.

[0054] The axial height of the connecting part 12 is less than or equal to the height of the mounting ring 13. This design ensures that after the electrode sheath 1 is assembled with the heating element, the connecting part 12 can be smoothly engaged in the mounting area formed by the height difference between the heating element and the heat conductor. The extension line of each connecting part 12 passes through the center of the mounting ring 13 to which it is connected, and the extension line of each connecting rod 22 passes through the center of the electrode ring 21 to which it is connected.

[0055] The electrode ring 21 is corrugated. This design gives the electrode ring 21 elastic deformation, increases the adaptability of installation gaps, and prevents poor contact.

[0056] A central mounting ring 131 is provided at the center of the electrode sheath 1. Several connecting parts 12 are connected together at their ends near the center of the electrode sheath 1 through the central mounting ring 131. Each connecting part 12 is provided with at least one circumferential mounting ring 132. The centers of adjacent circumferential mounting rings 132 are distributed on concentric circles with the center of the electrode sheath 1 as the center. That is, the circumferential mounting rings 132 located on the same circle are equidistant from the central mounting ring 131.

[0057] A central electrode ring 211 is positioned at the center of electrode 2. Several connecting rods 22 are connected together near the center of the electrode via the central electrode ring 211. Each connecting rod 22 has at least one circumferential electrode ring 212. The centers of adjacent circumferential electrode rings 212 are distributed on concentric circles centered on the center of electrode 2. That is, the circumferential electrode rings 212 on the same circle are equidistant from the central electrode ring 211. This arrangement allows the electrode sheath 1 to have mounting rings 13 at both the center and at circumferential positions a certain distance from the center. This ensures that the electrode sheath 1 can accommodate both the central electrode ring 211 and the circumferential electrode rings 212 on electrode 2, guaranteeing that the electrode assembly can conduct electricity in both the central region and the circumferential region a certain distance from the center.

[0058] In this embodiment, mounting rings 13 are evenly spaced on the same circle with the center of electrode sheath 1 as the center, and the included angle between each pair of adjacent connecting parts 12 is equal. Preferably, the mounting rings 13 include a central mounting ring 131 and six circumferential mounting rings 132 with their centers on the same circle. The included angle between each pair of connecting parts 12 is 60°, and the included angle between the lines connecting the centers of each pair of circumferential mounting rings 132 to the center of electrode sheath 1 is 60°. Correspondingly, electrode rings 21 are evenly spaced on the same circle with the center of electrode 2 as the center, and the included angle between each pair of adjacent connecting rods 22 is equal. Each electrode ring 21 includes a central electrode ring 211 and six circumferential electrode rings 212 with their centers on the same circle. The included angle between each pair of connecting rods 22 is 60°, and the included angle between the centers of each pair of circumferential electrode rings 212 to the center of the electrode is 60°. The circumferential mounting ring 132 divides the connecting portion 12 connected to it into several segments. Since the mounting ring 13 includes a central mounting ring 131 and a circumferential mounting ring 132 on each connecting portion 12, the circumferential mounting ring 132 on each connecting portion 12 divides the connecting portion 12 into two segments. These two segments of the connecting portion 12 are located on opposite sides of the circumferential mounting ring 132. The two ends of one segment of the connecting portion 12 are connected to the outer wall of the central mounting ring 131 and the outer wall of the circumferential mounting ring 132, respectively. One end of the other segment of the connecting portion 12 is connected to the outer wall of the circumferential mounting ring 132, and the other end is connected to the frame 11.

[0059] The circumferential mounting ring 132 divides the connecting part 12 connected to it into several segments, and the extension line of the connecting part 12 connected to the skeleton 11 can pass through the center of the electrode sheath 1, that is, the connecting part 12 divided into several segments are all on the same straight line.

[0060] The frame 11 has a ring-shaped structure, and one end of each connecting part 12 is connected to the inner ring of the frame 11. The extension line of the other end of each connecting part 12 passes through the center of the frame 11. Preferably, the frame 11 has a circular ring-shaped structure, which ensures that any point on the frame 11 is equidistant from the center of the electrode sheath 1, thereby ensuring the consistency of the length of each connecting part 12, and at the same time, that the connecting parts 12 cooperate with the frame 11 to enhance the overall strength of the electrode sheath 1.

[0061] The mounting ring 13 includes a bottom wall and an annular step 1332. The annular bottom wall 1331 and the annular step 1332 form a mounting groove 133, and the connecting part 12 is connected to the outer wall of the annular step 1332. The bottom wall is annular 1331, and a through hole is provided on the annular bottom wall 1331. The inner diameter of the through hole is less than or equal to the inner diameter of the electrode ring 21, and the outer diameter of the annular bottom wall 1331 is greater than or equal to the outer diameter of the electrode ring 21. This arrangement ensures that after the electrode ring 21 is placed in the mounting groove 133, the bottom wall of the mounting ring 13 can cover the electrode ring 21, preventing the electrode ring 21 from contacting external components and thus causing leakage. At the same time, the annular step 1332 on the mounting ring 13 protects and limits the electrode ring 21 on the electrode 2, thereby preventing the electrode ring 21 and the electrode from moving in series. It can also limit the conductive ring and heating element placed between the two electrode rings 21, as well as the heat-conducting spring between the heating element and the heat conductor, to prevent them from moving up and down.

[0062] The connecting part 12 is provided with an assembly groove 121 for placing the connecting rod 22 of the electrode. This arrangement allows the connecting rod 22 on the electrode 2 to be stably placed in the connecting part 12 of the electrode sheath 1, thereby ensuring the protection of the connecting rod 22 by the electrode sheath 1 and preventing deformation of the electrode assembly due to shaking of the connecting rod 22 during movement.

[0063] The mounting groove 121 on the connecting part 12 communicates with the mounting groove 133. The connection point between the mounting groove 121 and the mounting groove 133 is located at the connection point between the connecting part 12 and the electrode ring 21. This arrangement allows the connecting rod 22 connecting the electrode ring 21 to be smoothly inserted into the mounting groove 121.

[0064] A protrusion 122 is provided on the portion of the connecting part 12 that connects to the outermost mounting ring 13 away from the center of the electrode sheath 1. The protrusion 122 extends in the direction toward the frame 11. The protrusion 122 and the mounting groove 133 are located on the same side of the electrode sheath 1, and the height of the protrusion 122 is less than or equal to the height of the annular step 1332. The protrusion 122 extends to the edge of the frame 11. This arrangement enhances the strength of the connecting part 12 and ensures that the electrode sheath 1 will not break during use and transportation.

[0065] The frame 11 is provided with a limiting step 112 and a mounting buckle 111. The limiting step 112 and the mounting buckle 111 are used to connect with the fixing frame for subsequent wrapping of the heat conductor. The mounting buckle 111 is used to fasten or snap into the buckle groove on the fixing frame, and the limiting step 112 is used to abut against the end face of the fixing frame, which can enhance the strength of the frame 11. During the installation of the electrode sheath 1 and the fixing frame, the limiting step 112 applies pressure to the fixing frame, thereby supporting the frame 11 and preventing local deformation when the electrode sheath 1 and the fixing frame are fastened together.

[0066] Example 2

[0067] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0068] In this embodiment, the end of each connecting part 12 away from the frame 11 extends to the center of the electrode sheath 1, and one end of several connecting parts 12 is connected at the center of the electrode sheath 1; the end of each connecting rod 22 facing the center of the electrode extends to the center of the electrode, and one end of several connecting rods 22 is connected at the center of the electrode. This arrangement ensures that the connection point of several connecting parts 12 is located at the center of the electrode sheath 1, and the connection point of several connecting rods 22 is located at the center of the electrode, thereby ensuring the uniformity of the distribution of the mounting rings 13 on the connecting parts 12 and the uniformity of the distribution of the electrode rings 21 on the connecting rods 22. This ensures that the mounting rings 13 and the electrode rings 21 are evenly distributed outward from the center of the electrode assembly with intervals, thus ensuring the uniformity of conductivity.

[0069] Example 3

[0070] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0071] In this embodiment, at least two circumferential central mounting rings 131 are provided on each connecting part 12 in the radial direction.

[0072] Example 4

[0073] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0074] In this embodiment, the extension line of a connecting portion 12 connected to the skeleton 11 is deviated from the center of the electrode sheath 1. That is, the connecting portion 12 divided into several segments is not on the same straight line. Only the connecting portion 12 connected to the central mounting ring 131 or whose end is located at the center of the electrode sheath 1 passes through the center of the electrode sheath 1 and the skeleton 11.

[0075] Example 5

[0076] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0077] refer to Figure 4 As shown, in this embodiment, a positioning strip 221 extends from the outer wall of the electrode ring 21 on the side away from the electrode center; a positioning groove that mates with the positioning strip 221 is provided on the connecting part 12. The positioning strip 221 is provided on the outer wall of the outermost circumferential electrode ring 212 away from the electrode center and extends in a direction away from the electrode center. The length of the positioning strip 221 is less than or equal to the length of the positioning groove that it is adapted to install. This allows the electrode to be positioned and installed in the electrode sleeve 1 after the positioning strip 221 and the positioning groove are assembled, preventing incorrect electrode assembly position.

[0078] Example 6

[0079] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is as follows:

[0080] refer to Figure 3 and 5 As shown, in this embodiment, the electrode sleeve 1 is further provided with a mounting portion 123, which is located on the side of the connecting portion 12 between the central mounting ring 131 and the circumferential mounting ring 132. The mounting portion 123 has a mounting opening for matching with the assembly hole on the heat conductor. A fastener passes through the mounting opening and the assembly hole to further fix the heat conductor between the two electrode sleeves 1. The mounting portion 123 includes a bottom wall and two side walls, both connected to the connecting portion 12. The side walls extend along the side opposite to the mounting groove 133, and extend towards the front of the electrode sleeve 1. The bottom wall has a mounting opening. The two side walls enhance the strength of the mounting portion, ensuring sufficient strength and stability during installation and use.
