[0042] Dust filtration technology is used to remove various dust particles from the air. Common dust filtration technologies include: mechanical filtration, electrostatic filtration, wet filtration, molecular adsorption, centrifugal separation, nanotechnology filtration, filter bags, etc. Among them, electrostatic precipitation technology has attracted more and more attention for its high efficiency, no consumables, and easy maintenance. Currently, the main electrostatic filtration technologies are:
[0043] Ion sedimentation: Ions are generated by an ion generator. These ions collide with dust particles in the air, making the dust particles charged. The charged dust particles will attract and agglomerate with each other under the action of an electric field and finally settle to the ground or other objects due to gravity;
[0044] Electrostatic precipitator: The high-voltage electric field is used to charge the dust particles in the air, and the charged dust particles are adsorbed onto the dust collection plate with the opposite charge under the action of the electric field force;
[0045] Insulated electrostatic precipitation: It relies on monopolar negative ions, relies on a wire plate or ions to charge dust, bacteria, and viruses in the air, and is adsorbed onto the surface of the dust collection plate by the high-voltage electric field force formed by the dust collection plate with surface insulation and internal conductivity;
[0046] Ion + electret dust collection net technology: The negative ion generator is used to charge the dust particles in the air, and then the charged dust particles are adsorbed onto the surface of the filter net through the filter net with an electret electric field.
[0047] However, in the existing electrostatic dust removal technologies, the purification efficiency of the ion sedimentation technology is low and the purification upper limit is low; the metal plates used in the electrostatic precipitator technology are prone to generating electric arcs, releasing ozone, and producing unpleasant current sounds during operation; in the ion + electret dust collection net technology, in addition to the ion generator, the electret dust collection net needs to be frequently replaced; in the insulated electrostatic dust removal, there are problems such as large wind resistance, complex structure, high processing cost, local electric field loss, and inability to achieve overall filtration, and the conductive graphite and the like used in this technology as high-voltage conductive materials have a low conductivity coefficient, which will cause high-voltage loss.
[0048] The present utility model provides an electrostatic dust removal module.
[0049] Please refer to Figure 1 、 Figure 2 and Figure 4 In an embodiment of the present utility model, the electrostatic dust removal module includes:
[0050] An installation shell 100 and a bracket 200, the installation shell 100 forms an air passage space 110, the bracket 200 is disposed in the air passage space 110 and extends along a first direction, and limiting structures are formed on opposite sides of the bracket 200 in the air passage direction; and
[0051] At least two electrode members 300, the electrode members 300 are disposed in the air passage space 110, at least two electrode members 300 include a positive electrode member 301 and a negative electrode member 302, the positive electrode member 301 and the negative electrode member 302 are respectively disposed on opposite sides of the bracket 200 in the air passage direction and are connected to the corresponding limiting structures;
[0052] The electrode member 300 includes a plurality of electrode bodies 310 extending along a second direction, an insulating layer 340 covers the surface of the electrode body 310, and the electrode bodies 310 of the positive electrode member 301 and the electrode bodies 310 of the negative electrode member 302 are alternately spaced apart in the first direction.
[0053] The technical solution of the present utility model sets a bracket 200 in the air passage space 110 on the installation shell 100, the air passage space 110 is used for gas to flow in the air passage direction, limiting structures are formed on opposite sides of the bracket 200 in the air passage direction, wherein, for any one side of the limiting structure, at least one positive electrode member 301 or negative electrode member 302 is distributed and connected to the corresponding limiting structure. In this way, under the action of the limiting structure, the positional relationship between the positive electrode member 301 and the negative electrode member 302 is kept stable, that is, the electrode bodies 310 provided by the two are stably alternately distributed in the first direction, ensuring that the overall electric field formed by the electrode member 300 is more uniform. At the same time, an insulating layer 340 is provided on the electrode body 310 to avoid the occurrence of electric arc phenomena, ensuring the conductive ability of the electrode body 310, thereby avoiding the phenomenon of local electric field loss and improving the filtration efficiency, that is, improving the dust removal effect.
[0054] It should be noted that, as Figure 1 shown, the first direction is the width direction of the air passage space 110, and the second direction is the length direction of the air passage space 110. At the same time, it is also the extending direction of the electrode body 310. It can be understood that the first direction and the second direction are angularly distributed. In this embodiment, the first direction and the second direction are perpendicular to each other. Under the supporting action of the bracket 200, the positive electrode member 301 and the negative electrode member 302 are misaligned in the air passage direction, that is, in the first direction, the electrode body 310 of the positive electrode member 301 and the electrode body 310 of the negative electrode member 302 have relative parts to form a uniform electric field. In addition, with the bracket 200 as a reference, in the air passage direction, at least one electrode member 300 is provided on either side of the bracket 200, and at least the positive electrode member 301 and the negative electrode member 302 with opposite polarities are provided on the opposite sides of the bracket 200, which is manifested as: one positive electrode member 301 is provided on one side of the bracket 200, and two negative electrode members 302 are provided on the other side, or one positive electrode member 301 is provided on one side of the bracket 200, and one positive electrode member 301 and one negative electrode member 302 are provided on the other side, etc.
[0055] For any point of any electrode member 300, the potential value at its location is the same. In this way, the voltage between the electrode body 310 of the adjacent positive electrode member 301 and the electrode body 310 of the negative electrode member 302 is the same. Without loss of generality, the distance between the adjacent electrode bodies 310 is the same, so as to ensure that the electric field force between the adjacent electrode bodies 310 is uniform and fills the air passage space 110, thus avoiding the defect of local high-voltage field and ensuring the dust removal effect. In addition, when installing the electrode member 300 in the air passage space 110, the electrode member 300 is connected to the corresponding limiting structure and is electrically connected to the power supply component on the installation shell 100 at the same time. The assembly operation is convenient, and the assembled electrostatic dust removal module is stable and reliable.
[0056] Compared with the ion sedimentation technology, this embodiment can continuously remove dust in the air without being affected by the electrostatic adsorption force, with a high purification upper limit and purification efficiency. For an electrostatic precipitator, the insulating layer 340 provided in this embodiment can prevent the generation of arcs between the electrode bodies 310 of the positive electrode member 301 and the negative electrode member 302, avoiding the release of ozone and reducing the noise during the working process, and also preventing the arcs from affecting the conductivity of the electrode bodies 310, thus avoiding the situation of local electric field loss. For the ion + electret dust collection technology, the dust collected by the electrode bodies 310 in this embodiment will fall off when not energized, and repeat dust collection after being energized, is not easily saturated, does not need to be frequently replaced, reducing the maintenance cost and inconvenience for users. For the insulated electrostatic precipitation technology, the electric field force is evenly distributed in this embodiment, achieving better overall filtration, ensuring the purification effect, and the electrode bodies 310 do not use materials with a low conductivity coefficient such as conductive graphite, reducing the pressure loss and improving the efficiency and effect of electrostatic precipitation.
[0057] In one embodiment, please refer to Figure 2 and Figure 3 , the limiting structure includes a plurality of card slots 210 spaced apart in the first direction. In the air passing direction, the openings of the card slots 210 on the opposite sides of the bracket 200 are arranged in opposite directions, and the electrode body 310 is clamped in the corresponding card slot 210. During the assembly of the electrostatic dust collection module, the electrode bodies 310 of the negative electrode member 302 are respectively clamped in a plurality of card slots 210 on one side of the bracket 200 in the air passing direction. Similarly, the electrode bodies 310 of the positive electrode member 301 are respectively clamped in a plurality of card slots 210 on the other side of the bracket 200 in the air passing direction. The corresponding electrode bodies 310 are clamped tightly by the card slots 210, thereby stably installing the positive electrode member 301 and the negative electrode member 302 on the opposite sides of the bracket 200 in the air passing direction, and further ensuring the stability of the electrode member 300 in the air passing space 110. In this way, the electrode member 300 can be fixed by clamping the electrode body 310 in the corresponding card slot 210, which is convenient to operate and effectively prevents the electrode member 300 from deforming, ensuring the uniformity of the electric field force in the air passing space 110. Of course, in other embodiments, the limiting structure can also be configured as a screwing structure or an adhesive structure, etc.
[0058] Furthermore, in this embodiment, please continue to refer to Figure 2 and Figure 3, the opening of the card slot 210 expands outward to form a guiding structure 211. It can be understood that during the installation process of the electrode component 300, under the guiding action of the guiding structure 211, the electrode body 310 will be stably clamped in the corresponding card slot 210, so as to avoid damage during the clamping process of the electrode body 310, or to avoid the electrode body 310 being clamped in other card slots 210, resulting in misalignment of the installation of the electrode component 300 and affecting the uniformity of the electric field force in the air passage space 110. In this way, through the guiding action of the guiding structure 211, the accuracy and convenience of installing the electrode component 300 are improved. Without loss of generality, the guiding structure 211 is configured as an inclined plane at the opening of the card slot 210, and the distance between the opposite inclined planes increases in the opening direction to present a flared shape, thereby improving the installation convenience of the electrode body 310. Of course, in other embodiments, the distance between the opposite side walls in the card slot 210 can also be kept consistent, or in a shape with a narrower opening to clamp the electrode body 310.
[0059] Regarding the formed shape of the bracket 200, in this embodiment, please refer to Figure 2 and Figure 3 , the bracket 200 is in a wavy shape extending along the first direction, and a card slot 210 is formed between every two adjacent wave peaks or every two adjacent wave valleys of the bracket 200. It is easy to understand that, on the same side of the bracket 200 in the air passage direction, a card slot 210 is formed between two adjacent wave peaks, and on the opposite side of the bracket 200 in the air passage direction, two adjacent wave valleys form a card slot 210 on the other side. In this way, in the first direction, on one side of the bracket 200, the wave peaks and wave valleys are evenly and alternately distributed, and in the air passage direction, the wave peaks and wave valleys are on the same straight line. In this way, it can be ensured that the electrode bodies 310 of the positive electrode component 301 and the electrode bodies 310 of the negative electrode component 302 are evenly and alternately distributed in the first direction, ensuring the uniformity of the high-voltage electric field in the air passage space 110. In addition, the wavy bracket 200 has a simple structure and is convenient to form. Moreover, after clamping the positive electrode component 301 on one side, it will provide a fastening force for the clamping of the negative electrode component 302 on the other side, that is, the negative electrode component 302 and the positive electrode component 301 have an auxiliary effect of clamping each other on the bracket 200, thereby ensuring the stability of the electrode component 300 on the bracket 200. Of course, in other embodiments, on the premise of ensuring that the electrode bodies 310 of the positive electrode component 301 and the electrode bodies 310 of the negative electrode component 302 are evenly and alternately distributed in the first direction, the bracket 200 is configured as a square rod shape, and the card slot 210 is formed by a bayonet opened on the bracket 200.
[0060] In one embodiment, please refer to Figure 2, the electrostatic dust removal module is provided with a plurality of brackets 200, and the plurality of brackets 200 are distributed along the second direction. It can be understood that the slot 210 is arranged through the bracket 200 in the second direction, and at the same time, in the second direction, the slots 210 of different brackets 200 are connected in the same straight line. In this way, by setting a plurality of brackets 200, the supporting effect on the electrode member 300 is evenly divided in the second direction, and the stability of the electrode member 300 in the wind space 110 is improved, thereby ensuring a stable dust removal effect, and different brackets 200 have slots 210 in the same straight line in the second direction, so as to avoid deformation of the electrode body 310 during installation, so as to ensure the uniformity of the high-voltage electric field force in the wind space 110, and avoid the situation of local electric field loss, thereby ensuring the dust removal effect. Of course, in other embodiments, when the end of the electrode member 300 in the second direction is connected to the mounting shell 100, only one bracket 200 can be set in the middle of the wind space 110, so as to ensure the stability of the electrode member 300 in the wind space 110.
[0061] Regarding the molding method of the mounting shell 100 and the bracket 200, in this embodiment, please refer to Figures 1 to 3 The bracket 200 and the mounting shell 100 are integrally formed, or they are separately formed and fixedly connected. When the bracket 200 and the mounting shell 100 are integrally formed, the electrode component 300 can be directly connected to the bracket 200, which reduces the number of accessories and facilitates production and assembly. When the bracket 200 and the mounting shell 100 are separately formed, the bracket 200 is in the wind space 110, and its end is connected to the mounting shell 100. The position of the bracket 200 can be flexibly adjusted to ensure the stability of the electrode component 300 in the wind space 110. At the same time, when the bracket 200 is damaged, the bracket 200 can be directly replaced, which improves the convenience of maintenance and saves maintenance costs. Without loss of generality, when the mounting shell 100 and the bracket 200 are separately formed, the bracket 200 can be connected to the mounting shell 100 by snapping or screwing.
[0062] In this embodiment, please refer to Figure 1 and Figure 2 , the material of the mounting shell 100 is an insulating material. In this way, the positive electrode member 301 and the negative electrode member 302 are prevented from being electrically connected, and the stability of the electric field force in the air flow space 110 is guaranteed. At the same time, the mounting shell 100 also forms an insulating protection for the electrode member 300 to prevent leakage or affect the stability of the electric field in the air flow space 110. Similarly, the material of the bracket 200 is also configured as an insulating material.
[0063] In one embodiment, please refer to Figures 4 to 6, the electrode body 310 is plate-shaped, and the plate surfaces of multiple electrode bodies 310 are arranged opposite to each other in the first direction. It can be understood that in this embodiment, the air passing direction is perpendicular to the first direction. The plate surfaces of the electrode bodies 310 are arranged opposite to each other in the first direction, and at the same time, the plate surfaces of the electrode bodies 310 are also parallel to the air passing direction. In this way, while ensuring the dust removal effect of the electrode member 300, it avoids the electrode plate from obstructing the airflow passing through the air passing space 110, ensuring the smoothness of air flow. In addition, when the distance of the air passing space 110 in the first direction is fixed, the plate surfaces of multiple electrode bodies 310 are arranged opposite to each other in the first direction, which can improve the arrangement density of the electrode bodies 310 as much as possible, improve the uniformity of the high-voltage electric field, and also improve the efficiency of electrostatic dust removal. Of course, in other embodiments, the plate surface of the electrode body 310 needs to be parallel to the air passing direction. At this time, the air passing direction can be set at a non-perpendicular angle to the first direction. At this time, the plate surfaces of multiple electrode bodies 310 are also set at a non-perpendicular angle to the first direction, presenting an overall inclined shape.
[0064] Furthermore, in this implementation, please refer to Figures 4 to 6, the electrode member 300 further includes two substrates 320 spaced apart and opposite to each other in the second direction. The mounting shell 100 is provided with electrical connection terminals 120 for electrically connecting the substrates 320. The substrates 320 extend in the first direction. Two ends of the electrode body 310 are respectively connected to the two substrates 320 and stand up relative to the substrates 320. It can be understood that for the same electrode member 300, the same ends of the multiple electrode bodies 310 thereon are all connected to the same substrate 320, and then the substrate 320 is electrically connected to the electrical connection terminals 120 on the mounting shell 100 to achieve the purpose of powering the electrode member 300. In this way, power is supplied to the electrode member 300 through one substrate 320, ensuring that the multiple electrode bodies 310 on the electrode member 300 are at the same potential, and further ensuring the voltage uniformity between the electrode body 310 of the positive electrode member 301 and the electrode body 310 of the adjacent negative electrode member 302. In addition, the electrode body 310 stands up relative to the substrate 320, and the substrate 320 can extend in the first direction, so that the air passage space 110 is arranged in a flat shape, expanding the area through which the air flow can pass in the air passage space 110, and also ensuring the contact area between the electrode body 310 and the air flow, thereby improving the dust removal efficiency. It should be noted that after the electrode member 300 is installed in the air passage space 110, the substrate 320 abuts against the conductive connection portion 330 on the mounting shell 100. The electrical connection terminal 120 is configured as a spring piece, and the spring piece is electrically connected to the wire connection portion 330 and is electrically connected to an external power source through the spring piece. Among them, the electrode member 300 needs to be configured with high voltage. A transformer can be integrated on the mounting shell 100 in the electrostatic dust removal module, and the electrostatic dust removal module can be connected to the mains power, or a transformer is provided in the device where the electrostatic dust removal module is arranged, and the electrical connection terminal 120 is connected to the mains power through the transformer. Of course, in other embodiments, the electrode bodies 310 of the positive electrode member 301 can be independently connected to the electrical connection terminals 120 on the mounting shell 100.
[0065] Further, in one embodiment, please refer to Figures 7 to 9 , the electrode member 300 further includes a connection portion 330. The electrode body 310 is connected to the substrate 320 through the connection portion 330. The width of the connection portion 330 is smaller than the width of the electrode body 310. The extending direction of the connection portion 330 is parallel to or at an angle to the second direction. The connection portion 330 is formed with a folding structure so that the electrode body 310 stands up relative to the substrate 320. It should be noted that the connection portion 330 has good toughness. During the process of standing up the electrode body 310, the connection portion 330 deforms to form a folding structure. In this way, the automated production of the electrode member 300 is realized through the folding operation, the process is simple, the production time and processes are greatly reduced, the operation is convenient, and the cost is reduced accordingly. Specifically, in this embodiment, as Figure 7As shown, when the electrode body 310 of the electrode member 300 is not erected, the extending direction of the connecting portion 330 forms an angle with the second direction, that is, the extending direction of the electrode body 310. The operation of erecting the electrode body 310 can enable the connecting portion 330 to be deformed smoothly, improving the forming convenience of the electrode member 300; or, in another embodiment, as Figure 8 and Figure 9 shown, when the electrode body 310 of the electrode member 300 is not erected, the extending direction of the connecting portion 330 is parallel to the second direction, that is, the extending direction of the electrode body 310. The space occupied by erecting the electrode body 310 is relatively small, and it can be achieved by rotating the electrode body 310 around the second direction. Among them, the connecting portion 330 can be as Figure 8 shown, arranged in a T shape with the electrode body 310, or, as Figure 9 shown, the connecting portion 330 is arranged in an L shape with the electrode body 310. In addition, the widths of both the connecting portion 330 and the electrode body 310 are perpendicular to the extending direction. The width of the connecting portion 330 is set to be smaller than the width of the electrode body 310, which can reduce the difficulty of the connecting portion 330 turning over to form a turning structure, improving the forming convenience of the electrode body 310.
[0066] In one embodiment, please refer to Figure 5, the number of the positive electrode members 301 and the negative electrode members 302 is correspondingly set to one or more than two. When the number of the positive electrode members 301 and the negative electrode members 302 is correspondingly set to more than two, at least one electrode body 310 of another electrode member 300 of the same type is inserted between two adjacent electrode bodies 310 of the electrode member 300. It can be understood that multiple positive electrode members 301 are electrode members 300 of the same type, and multiple negative electrode members 302 are electrode members 300 of the same type. Taking the positive electrode member 301 as an example, on one side of the bracket 200 in the air passing direction, at least two positive electrode members 301 are stacked. In the first direction, the electrode body 310 on one positive electrode member 301 is adjacent to the electrode body 310 of another positive electrode member 301, so that in the first direction, two adjacent electrode bodies 310 belong to different positive electrode members 301. In this way, after stacking these multiple positive electrode members 301, compared with the formation of the electrode plates on one positive electrode member 301 in an erected manner, the electrode plate density of the positive electrode member 301 on one side of the bracket 200 in the air passing direction can be increased, so as to increase the density and uniformity of the electric field force. Similarly, for the negative electrode member 302, on the other side of the bracket 200 in the air passing direction, at least two negative electrode members 302 are stacked. In the first direction, the electrode body 310 on one negative electrode member 302 is adjacent to the electrode body 310 of another negative electrode member 302, so that in the first direction, two adjacent electrode bodies 310 belong to different negative electrode members 302. In this way, after stacking these multiple negative electrode members 302, compared with the formation of the electrode plates on one negative electrode member 302 in an erected manner, the electrode plate density of the negative electrode member 302 on one side of the bracket 200 in the air passing direction can be increased. In this way, after the positive electrode member 301 and the negative electrode member 302 are inserted opposite to each other on both sides of the slot 210 provided on the bracket 200, an electrode plate on the negative electrode member 302 is provided between any two adjacent electrode plates on the positive electrode member 301, ensuring that the electrode plates of the positive electrode member 301 and the electrode plates of the negative electrode member 302 are alternately distributed in the first direction, thereby increasing the arrangement density of the electrode plates. Without loss of generality, multiple electrode members 300 are stacked, and their substrates 320 are fixedly connected and conduct electricity with each other. When any substrate 320 is connected to the same electrical connection end 120, the potentials carried by the stacked multiple electrode members 300 are the same. Thus, the conductivity of the electrode member 300 is ensured, and voltage loss is avoided. Therefore, the overall potential of the electrostatic dust removal module is high and uniform, and the dust removal and filtration efficiency is high.
[0067] In one embodiment, please refer to Figure 4 and Figure 7, the electrode body 310 is erected by folding on a prefabricated plate, and the prefabricated plate is formed by stamping. In this way, after a crease is stamped on the prefabricated plate, the electrode body 310 is folded and erected, thus forming the electrode member 300 of this embodiment. The process is simple, greatly reducing the manufacturing time and processes, and thus reducing costs. Moreover, the electrode member 300 is formed by folding after stamping, with good structural stability, ensuring the stability of the high-voltage electric field in the air passage space 110. In another embodiment, as Figure 4 shown, the electrode member 300 is integrally formed by casting. It can be understood that the casting mold can flexibly set the arrangement density of the electrode bodies 310 according to requirements, so that the electrode bodies 310 on the electrode member 300 can meet the requirements of various electric field forces to adapt to various dust removal environments, improving the manufacturing flexibility and convenience of the electrode member 300. In addition, the casting method reduces the process of folding and erecting the electrode bodies 310, improving the production efficiency of the electrode member 300.
[0068] In one embodiment, please refer to Figure 4 . The insulating layer 340 is formed by attaching an insulating film or coating an insulating coating.

For the coating method, it can ensure the coverage rate of the insulating layer 340 on the surface of the electrode body 310, ensuring the insulating effect and avoiding the occurrence of arcing phenomena, thereby ensuring the user experience. Among them, for the electrode member 300 formed by stamping, the shape of the electrode body 310 can be stamped on the prefabricated plate first. At this time, the electrode body 310 is not erected. Then, an insulating material is attached or coated on the surface of the prefabricated plate, and the redundant insulating material is cut off by a mold, and then the electrode body 310 is erected to form the electrode member 300; or, after the shape of the prefabricated plate is stamped and the electrode body 310 is erected to form the electrode member 300, an insulating material is attached or coated on the electrode member 300; or, for the electrode member 300 formed by casting, after the electrode member 300 is formed, an insulating material is attached or coated on the electrode member 300. It can be understood that the above-mentioned forming process is simple, can greatly reduce the manufacturing time and processes, and thus reduce costs.

In particular, in this embodiment, the material of the insulating layer 340 is epoxy resin and fluoropolymer. For the material of the electrode member 300, in this embodiment, please refer to Figure 4 , the material of the electrode member 300 is a metal conductor and conductive plastic that meet the preset conductivity requirements. Among the metal conductors, they can be: copper plates, galvanized plates, stainless steel plates, aluminum plates, etc., to meet the conductivity requirements of high-voltage conduction, reduce the voltage drop loss, and thus ensure the stability of the electric field force in the air passage space 110.
