Description

Technical Field

[0001] This invention relates to the field of air purification device technology, specifically to a flexible electro-purification structure and dust removal device. Background Technology

[0002] Air particulate matter purification is receiving increasing attention. Currently, filtration is the primary method. However, due to the limited size of filter meshes, suspended particles smaller than the mesh diameter can still pass through, preventing efficient purification. Furthermore, filtration technology suffers from drawbacks such as high air resistance, secondary pollution, and the additional costs associated with frequent filter replacements. With advancements in air purification technology, electrostatic precipitators have emerged. Their advantages, including extremely low resistance, ability to handle fine particles, and high dust removal efficiency, have rapidly gained popularity.

[0003] Existing electro-purification modules are plate-shaped structures, with multiple modules connected sequentially to form a plate-type electro-purification module, or modules with a certain curvature surrounding each other to form a tubular electro-purification module. However, regardless of the combination, the shape of a single electro-purification module cannot be changed. To achieve a good fit on equipment surfaces with different curvatures, such as fans, indoor standing air conditioners, bathroom vents, and vehicle interiors, the electro-purification module needs to be "custom-made." This is complex, increases production costs, and is extremely inconvenient, thus limiting the application range of electro-purification modules.

[0004] Therefore, existing technologies need further development. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a flexible electro-purification structure and dust removal device to solve the technical problem that the electro-purification module cannot be deformed in related technologies, which limits the use of electro-purification technology.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: A flexible electro-purification structure is provided, comprising: multiple dust collection plates arranged sequentially and spaced apart; a discharge electrode that deforms under stress; a grounding electrode assembly, wherein each dust collection plate is located between the grounding electrode assembly and the discharge electrode, the grounding electrode assembly comprising multiple grounding electrodes connected sequentially, and adjacent grounding electrodes being rotatably arranged relative to each other; a telescopic assembly, wherein each dust collection plate is connected to the telescopic assembly, which deforms under stress, causing the dust collection plates to move with the deformation of the telescopic assembly; and two insulating plates, with the ends of the discharge electrode, the grounding electrode assembly, and the telescopic assembly respectively connected to each insulating plate. Pulling the insulating plates causes the discharge electrode and the telescopic assembly to deform, and each grounding electrode to rotate relative to the others.

[0007] Furthermore, the telescopic assembly includes a first connecting plate, a second connecting plate, a third connecting plate, and a fourth connecting plate, which are sequentially connected. The connection between the first and second connecting plates forms a first connecting portion, the connection between the second and third connecting plates forms a second connecting portion, and the connection between the third and fourth connecting plates forms a third connecting portion. Each dust collection plate is respectively disposed on the first, second, and third connecting portions, and all of the first, second, third, and fourth connecting plates can deform under stress.

[0008] Furthermore, the first and third connecting parts are both located on the side closer to the grounding electrode, and the second connecting part is located on the side closer to the discharge electrode.

[0009] Furthermore, the electro-purification structure also includes multiple fasteners, each of which is respectively installed on the first connecting part, the second connecting part, and the third connecting part. The fasteners are used to fix the dust collection plate.

[0010] Furthermore, there are multiple telescopic components, which are connected in sequence. The fourth connecting plate of the first telescopic component in two adjacent telescopic components is connected to the first connecting plate of the other telescopic component in two adjacent telescopic components.

[0011] Furthermore, the first connecting plate includes a first connecting segment, a second connecting segment, and a third connecting segment, which are connected sequentially. The first connecting segment and the third connecting segment are spaced apart. Each first connecting segment is connected to a respective fixing component. The second connecting plate includes a fourth connecting segment, a fifth connecting segment, and a sixth connecting segment, which are connected sequentially. The first connecting segment is connected to the fourth connecting segment to connect the first connecting plate to the second connecting plate. The fourth connecting segment and the sixth connecting segment are spaced apart. Each fourth connecting segment is connected to a respective fixing component. The first connecting plate and the second connecting plate are axially symmetrical about the dust collection plate as the axis of symmetry.

[0012] Furthermore, when no external force is applied, the first connecting segment is parallel to the third connecting segment, and the fourth connecting segment is parallel to the sixth connecting segment.

[0013] Furthermore, when no external force is applied, the third connecting plate and the second connecting plate are arranged symmetrically about the dust collection plate located at the second connecting part, and the fourth connecting plate and the third connecting plate are arranged symmetrically about the dust collection plate at the third connecting part.

[0014] Furthermore, the electric purification structure also includes multiple connecting rings, each connecting ring being connected to two adjacent grounding electrodes. Each grounding electrode has a rotating part at both ends, and the rotating parts of two adjacent grounding electrodes are connected to the connecting rings. The connecting rings allow the two rotating parts to rotate relative to each other, thereby deforming the grounding electrode assembly.

[0015] Furthermore, the connecting ring is provided with two openings and a rotating cavity for the rotating part to rotate. The two openings are arranged opposite each other, and the rotating parts of the two adjacent grounding electrodes enter the rotating cavity through their respective openings.

[0016] Furthermore, a sliding groove is provided on the connecting ring, and the sliding groove is correspondingly provided with the rotating part. The angle between the connecting ring and the grounding electrode is changed by the rotating part moving in the sliding groove.

[0017] A dust removal device includes a housing and a mounting port, and also includes a flexible electro-purification structure as described above. The insulating plate of the flexible electro-purification structure is fixed on the housing, and the electro-purification structure is correspondingly arranged with the mounting port.

[0018] Beneficial effects:

[0019] 1. The flexible electro-purification structure of the present invention, combined with a telescopic spring discharge electrode, a telescopic component and a mutually rotatable grounding electrode, changes the curvature of the electro-purification structure by rotation and bending to achieve variable cross-section purification. As a purification accessory, it can be conveniently applied to small space scenarios such as desktop purification, vehicle purification, bathroom or kitchen, and can also be matched with the curved cross-section of air conditioners. It can be bent into a suitable size according to needs and installed at the air inlet of air conditioners to achieve efficient application of a single module in multiple places.

[0020] 2. The flexible electro-purification structure of the present invention, which covers the dust collection plate between the discharge electrode and the ground electrode, can ensure that the plasma is fully filled in the dust collection component, avoid the dissipation of charge during the blowing and movement process, and has a higher purification effect.

[0021] 3. The dust removal device of the present invention is no longer limited by the size of the electro-purification module in the design of the ventilation opening, which simplifies the manufacturing process. Attached Figure Description

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] According to an embodiment of the present invention, a flexible electro-purification structure is provided; please refer to [link / reference]. Figures 1 to 8The system includes: multiple dust collection plates 1, arranged sequentially and spaced apart; discharge electrodes 2, which deform under pressure; a grounding electrode assembly 3, with each dust collection plate 1 located between the grounding electrode assembly 3 and the discharge electrode 2, the grounding electrode assembly 3 including multiple grounding electrodes 31, which are connected sequentially and rotatably arranged between adjacent grounding electrodes 31; a telescopic assembly 4, with each dust collection plate 1 connected to the telescopic assembly 4, which deforms under pressure, causing the dust collection plates 1 to move accordingly; and two insulating plates 5, with the ends of the discharge electrodes 2, the grounding electrode assembly 3, and the telescopic assembly 4 respectively connected to the insulating plates 5. Pulling the two insulating plates 5 causes the discharge electrodes 2 and the telescopic assembly 4 to deform, and the grounding electrodes 31 to rotate relative to each other. The discharge electrodes 2 are telescopic spring electrodes, and the dust collection plates 1 are located between each grounding electrode 31 and the telescopic spring electrodes, ensuring that the plasma is fully filled between the dust collection plates 1, preventing the discharge from being blown out and the dissipation of charge during the movement path, thus achieving efficient purification. In use, according to the surface curvature of the mounting opening, pull the two insulating plates 5 to cause the grounding electrodes 31 to rotate relative to each other. The telescopic spring electrodes extend, deform, and bend, and the telescopic component 4 also bends as the insulating plates 5 at both ends move. The grounding electrodes 31, telescopic spring electrodes, and telescopic component 4 all deform together until they are adjusted to a suitable curvature. By changing the curvature of the electro-purification structure through rotation and bending, variable cross-section purification is achieved. As a purification accessory, it can be conveniently applied to small space scenarios such as desktop purification and vehicle purification. It can also be matched with the curved cross-section of air conditioners and installed at the air inlet of air conditioners, realizing efficient application of a single module in multiple locations and greatly improving the application range of electro-purification technology. The bendable electro-purification structure of this embodiment solves the technical problem in related technologies where the electro-purification module cannot be deformed, which limits the use of electro-purification technology.

[0034] See Figure 1 and Figure 2In the flexible electro-purification structure of this embodiment, the telescopic component 4 includes a first connecting plate 41, a second connecting plate 42, a third connecting plate 43, and a fourth connecting plate 44. The first connecting plate 41, the second connecting plate 42, the third connecting plate 43, and the fourth connecting plate 44 are connected in sequence. The connection between the first connecting plate 41 and the second connecting plate 42 forms a first connecting portion 45, the connection between the second connecting plate 42 and the third connecting plate 43 forms a second connecting portion 46, and the connection between the third connecting plate 43 and the fourth connecting plate 44 forms a third connecting portion 47. Each dust collection plate 1 is respectively disposed on the first connecting portion 45, the second connecting portion 46, and the third connecting portion 47. The first connecting plate 41, the second connecting plate 42, the third connecting plate 43, and the fourth connecting plate 44 can all deform under stress. The first connecting plate 41 and the second connecting plate 42 are connected to the dust collection plate 1 through the first connecting part 45. The second connecting plate 42 and the third connecting plate 43 are connected through the second connecting part 46. The third connecting plate 43 and the fourth connecting plate 44 are connected through the third connecting part 47. Pulling the insulating plates 5 on both sides causes the first connecting plate 41, the second connecting plate 42, the third connecting plate 43 and the fourth connecting plate 44 to deform under force, thereby driving the dust collection plates 1 on the first connecting part 45, the second connecting part 46 and the third connecting part 47 to move. The distance between two adjacent dust collection plates 1 changes with the deformation of the connecting plate, ensuring that the telescopic component 4 bends synchronously with the telescopic spring electrode and the multiple grounding electrodes 31 that rotate with each other, thereby matching the arc surface at the mounting opening.

[0035] See Figure 1 and Figure 2 In the flexible electro-purification structure of this embodiment, the first connecting part 45 and the third connecting part 47 are both located on the side near the grounding electrode 31, and the second connecting part 46 is located on the side near the discharge electrode 2. The two connecting plates form a V-shaped structure, and the connection point is the tip of the V-shaped structure. The tip is alternately arranged near the grounding electrode 31 and near the discharge electrode 2.

[0036] See Figure 1 , Figure 2 and Figure 3 In this embodiment, the flexible electro-purification structure further includes multiple fixing members 6, each of which is respectively disposed on the first connecting part 45, the second connecting part 46, and the third connecting part 47. The fixing members 6 are used to fix the dust collection plate 1. The fixing members 6 are made of adhesive, and one end of the dust collection plate 1 can be fixed to the top tip of the V-shape of the two connecting plates by potting adhesive, so that each dust collection plate 1 can form a fixed angle L.

[0037] See Figure 1In this embodiment, the flexible electro-purification structure comprises multiple telescopic components 4, which are connected sequentially. The fourth connecting plate 44 of one of two adjacent telescopic components 4 is connected to the first connecting plate 41 of the other adjacent telescopic component 4. The multiple telescopic components 4 are connected end-to-end, forming a fourth connecting portion 48 at the connection point between the fourth connecting plate 44 of one telescopic component 4 and the first connecting plate 41 of another adjacent telescopic component 4. Both the fourth connecting portion 48 and the second connecting portion 46 are located on the side closest to the discharge electrode 2. The number of telescopic components 4 in the electro-purification module is selected according to the size of the mounting opening.

[0038] See Figure 2 In this embodiment, the flexible electro-purification structure includes a first connecting plate 41 comprising a first connecting segment 411, a second connecting segment 412, and a third connecting segment 413, which are connected sequentially. The first connecting segment 411 and the third connecting segment 413 are spaced apart. Each first connecting segment 411 is connected to a corresponding fixing member 6. The second connecting plate 42 comprises a fourth connecting segment 421, a fifth connecting segment 422, and a sixth connecting segment 423, which are connected sequentially. The first connecting segment 411 is connected to the fourth connecting segment 421 to connect the first connecting plate 41 to the second connecting plate 42. The fourth connecting segment 421 and the sixth connecting segment 423 are spaced apart. Each fourth connecting segment 421 is connected to a corresponding fixing member 6. The first connecting plate 41 and the second connecting plate 42 are axially symmetrical about the dust collection plate 1. The second connecting segment 412 is connected in the opposite direction to the first connecting segment 411 and the third connecting segment 413 at both ends, and there are included angles between the second connecting segment 412 and the first connecting segment 411, and between the second connecting segment 412 and the third connecting segment 413. When an external force pulls the insulating plates 5 on both sides, the second connecting segment 412 and the third connecting segment 413 rotate relative to the first connecting segment 411, thereby deforming the first connecting plate 41. Similarly, using the above structure, the fifth connecting segment 422 and the sixth connecting segment 423 rotate relative to the fourth connecting segment 421, thereby deforming the second connecting plate 42.

[0039] See Figure 1 , Figure 2 and Figure 3In this embodiment, the flexible electro-purification structure, when no external force is applied, has the first connecting segment 411 parallel to the third connecting segment 413, and the fourth connecting segment 421 parallel to the sixth connecting segment 423. The third connecting plate 43 and the second connecting plate 42 are axially symmetrical about the dust collection plate 1 located at the second connecting portion 46, and the fourth connecting plate 44 and the third connecting plate 43 are axially symmetrical about the dust collection plate 1 of the third connecting portion 47. Figure 3 As shown, the angle L between the dust collection plate 1 and the first connecting section 411 is such that, when there is no external force, the first connecting section 411 is parallel to the third connecting section 413, meaning that the angle between the dust collection plate 1 and the third connecting section 413 is also L. The angle L1 between the second connecting section 412 and the third connecting section 413 is such that, when subjected to external force, the second connecting section 412 and the third connecting section 413 rotate relative to the first connecting section 411, so that the range of the active angle between them moving synchronously is L2, thereby making the telescopic component 4 extendable and retractable.

[0040] See Figure 1 The flexible electro-purification structure of this embodiment further includes multiple connecting rings 7. Each connecting ring 7 is connected to two adjacent grounding electrodes 31. Rotating portions 311 are provided at both ends of each grounding electrode 31. The rotating portions 311 of each adjacent grounding electrode 31 are connected to the connecting rings 7. The connecting rings 7 allow the two rotating portions 311 to rotate relative to each other, thereby deforming the grounding electrode assembly 3. The rotating portions 311 at both ends of the grounding electrode 31 are connected to the connecting rings 7, and the connecting rings 7 connect two adjacent grounding electrodes 31. The grounding electrode assembly 3 is flexible due to the rotation of the connecting rings 7 on each rotating portion 311.

[0041] There are several ways to design the connecting ring 7, for example Figure 4 The structure shown has two openings 71 on the connecting ring 7, and the inside is a rotating cavity 72 for the rotating part 311 to rotate. The openings 71 are symmetrically arranged, and the rotating parts 311 of the two adjacent grounding electrodes 31 enter the rotating cavity 72 through each opening 71.

[0042] While keeping the structure of the connecting ring 7 unchanged, the present invention also provides another embodiment in which the rotating part 311 has a toothed structure, and the change of the center angle of the arc surface is achieved through the meshing motion of the teeth of the two rotating parts 311.

[0043] The present invention also provides a third embodiment, such as... Figure 5 and Figure 6 In this embodiment, the flexible electric purification structure has a groove 73 on the connecting ring 7. The rotating part 311 moves in the groove 73 to change the angle between the connecting ring 7 and the grounding electrode 31, thereby causing the grounding electrode assembly 3 to deform and bend.

[0044] See Figure 7 and Figure 8 The dust removal device of this embodiment includes a housing and a mounting port, as well as a flexible electro-purification structure as described above. The insulating plate 5 of the flexible electro-purification structure is fixed to the housing, and the flexible electro-purification structure is correspondingly arranged with the mounting port. The flexible purification module consists of a dust collection plate 1, a telescopic spring discharge electrode, a grounding electrode assembly 3, and a telescopic assembly 4. The overall module presents a sandwich structure. When the electro-purification structure is not deformed, the entire module is horizontal. The telescopic spring discharge electrode uses a spring spiral tungsten wire, which can deform within the elastic range of the spring to ensure normal discharge. The dust collection part is calculated using an electric field formula, which allows the thickness of the dust collection plate 1 to be controlled within 30mm. The dust collection material is a composite material with an insulating surface and an internally conductive surface, and the surface resistance is controlled between 10⁸ and 10⁹ Ω. Using this material, the spacing between the dust collection plates 1 can be reduced to 2-5mm, which allows for the application of a higher voltage at the same spacing compared to metal materials. The grounding electrode 31 is composed of a linear metal segment connected at both ends by a toothed mechanism. The rotation of the grounding metal segment is achieved by varying the meshing angles of the different teeth, with the rotation center angle ranging from 0 to 60°. The dust collection plate 1 is mounted on the retractable assembly 4 via a fixing member 6. During rotation, it acts as a guide, carrying the dust collection plate along with the insulating plates 5 at both ends. The discharge electrode 2, dust collection plate 1, and grounding electrode 31 are all isolated by insulators to prevent abnormal discharges such as arcing and creepage during power-on.

[0045] In this embodiment of the dust removal device with the electro-purification structure, the process is as follows: the air to be treated first passes through the spring discharge electrode to charge the particles, and then moves into the dust collection component, where the particles are collected using high-density dust collection plates.
