Description

Technical Field

[0001] The utility model relates to the technical field of air purification, and particularly relates to an improvement in the structure of an air purification device. Background Art

[0002] Among the existing air purification devices that are widely used, the one with better purification effect is the low-temperature plasma generating device. The outer layer of the emission electrode structure is basically a quartz glass tube with good insulation, but the internal electrodes vary greatly. There are mainly the following several types:

[0003] Graphite powder is directly filled inside the glass tube for conduction, and a metal wire is inserted as a conductive electrode. The advantage of this structure is that the carbon powder can completely fill the quartz tube, but the disadvantages are also obvious. The graphite powder is light in weight and is not easy to fill in the slender glass tube. An uninterrupted vibration compaction process is required, which may cause graphite powder dust, having a serious adverse impact on the health of operating workers;

[0004] Alternatively, metal powder is directly filled inside the glass tube. Although this structure solves the problem of being not easy to load due to light weight, it also brings about a significant increase in the weight of the electrode structure, and the particle size of the metal powder has a great influence on the filling quality. Uneven filling will affect the parallelism of the electrodes and the discharge effect, and the metal powder is expensive and not suitable for mass production.

[0005] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0006] In view of the problems pointed out in the background art, the utility model proposes a new electrode component structure. A hollow and conductive member with conductive function is arranged inside an insulating dielectric shell, and it can be directly inserted into the insulating dielectric shell during assembly. A notch is provided on the conductive member, enabling the conductive member to be deformed to ensure a tight fit between it and the inner wall of the insulating dielectric shell, thus ensuring the parallelism of the electrodes.

[0007] In some embodiments of this application, an air purification device is provided, including:

[0008] A grounding part for grounding;

[0009] A power supply part for connecting to a power supply to achieve power supply;

[0010] An electrode component, with two ends respectively connected to the grounding part and the power supply part, including:

[0011] An insulating dielectric shell, in which an installation space is formed;

[0012] A conductive component, assembled into the installation space for conducting electricity, the conductive component comprising:

[0013] A conductive member, which is hollow inside, and a notch portion extending along its axial direction is formed on the side wall of the conductive member. The notch portion is configured to cause the conductive member assembled inside the insulating dielectric shell to deform radially to fit closely on the inner wall of the insulating dielectric shell.

[0014] In some embodiments of the present application, an air purification device is provided, and the structure of the electrode component constituting its discharge is improved. A conductive member is arranged inside the electrode component. During assembly, the conductive member can be inserted into the insulating dielectric shell from one end, which is convenient for installation;

[0015] And the conductive member is hollow inside, with a light weight and low cost;

[0016] The notch portion provided on the conductive member can enable the conductive member to have a certain elastic deformation amount and can deform within a certain range. When the actual inner diameter of the insulating dielectric shell is larger than the reference inner diameter due to processing deviation, the conductive member will expand radially, thereby ensuring that the outer wall of the conductive member is adapted to the inner diameter of the insulating dielectric shell and remains in close contact with the inner wall of the insulating dielectric shell;

[0017] When the actual inner diameter of the insulating dielectric shell is smaller than the reference inner diameter due to processing deviation, the conductive member inserted inside it is compressed and deformed radially by the extrusion force of the inner wall of the insulating dielectric shell, and its size becomes smaller, also ensuring close contact with the inner wall of the insulating dielectric shell, thereby ensuring the parallelism and installation accuracy of the plasma electrode component.

[0046] In some embodiments of the present application, an air purification device is proposed, which can be used to be assembled on an air conditioner to purify the air flow in the air conditioner.

[0047] In some embodiments of the present application, the air purification device is a plasma generating device, which is arranged on the air flow path of the air conditioner, such as it can be arranged in the return air part, the air outlet part or inside the heat exchange air duct of the air conditioner.

[0048] In some embodiments of the present application, with reference to Figure 1 As shown, the air purification device is composed of a grounding part 400, a power supply part 500, and an emission electrode assembly transversely connected between the grounding part 400 and the power supply part 500.

[0049] The grounding part 400 is connected to the ground for realizing the grounding function.

[0050] The power supply part 500 can be used to be electrically connected to the emission electrode assembly to provide high-frequency high-voltage electricity to the generating electrode assembly.

[0051] In some embodiments of the present application, with reference to Figures 1-4 As shown, the emission electrode assembly is connected between the grounding part 400 and the power supply part 500 and includes:

[0052] Electrode components 600 are provided in multiple numbers, and the multiple electrode components 600 are arranged side by side.

[0053] In some embodiments of the present application, the multiple side-by-side arranged electrode components 600 are all transversely extended and arranged along the direction from the power supply part 500 to the grounding part 400.

[0054] In some embodiments of the present application, the multiple electrode components 600 are parallel to each other and the structures of the multiple electrode components 600 are exactly the same.

[0055] During connection, some of the multiple electrode components 600 are electrically connected to the power supply unit 500, and the other ends are mechanically connected to the grounding unit 400. The two ends are respectively supported and fixed by the power supply unit 500 and the grounding unit 400.

[0056] Another part of the electrode components 600 is connected to the grounding unit 400 to achieve grounding, and the other ends are connected and mechanically assembled to the power supply unit 500. The two ends are respectively supported and fixed by the power supply unit 500 and the grounding unit 400.

[0057] The multiple electrode components 600 electrically connected to the power supply unit 500 and the multiple electrode components 600 electrically connected to the grounding unit 400 are alternately arranged in sequence.

[0058] After the connection is completed, one end of one of the adjacent electrode components 600 is electrically connected to the power supply unit 500, and one end is assembled to the grounding unit 400.

[0059] One end of the other electrode component 600 is connected to the grounding unit 400 for grounding, and one end is assembled to the power supply unit 500.

[0060] The electrode components 600 electrically connected to the power supply unit 500 form high-voltage electrode components 600, and the electrode components 600 connected to the grounding unit 400 form grounding electrode components 600.

[0061] The high-voltage electrode components 600 are connected to the power supply unit 500, and the grounding electrode components 600 are connected to the grounding unit 400. The corresponding voltages of the high-voltage electrode components 600 and the grounding electrode components 600 are different. Therefore, a potential difference can exist between the adjacent high-voltage electrode components 600 and the grounding electrode components 600, and a high-frequency high-voltage electric field is formed. Through the high-frequency high-voltage electric field, the molecular chains of odor molecules can be broken up to form small molecule fragments.

[0062] In some embodiments of the present application, referring to Figure 1 As shown, a discharge gap 700 through which gas molecules flow is formed between two adjacent electrode components 600. The distance of the discharge gap 700 left between the two electrode components 600 is 2 to 5 mm.

[0063] When setting, the number of electrode components 600 can be set according to actual use requirements. The electrode components 600 can be set to 4, 6, 8, etc.

[0064] When the indoor polluted air passes through the discharge gap 700 formed between the two electrode components 600, the molecular chains of harmful gases are directly broken up under the action of the high-frequency high-voltage electric field.

[0065] Meanwhile, plasma is generated during the ionization of air by the electrode component 600. The plasma further reacts with the broken small molecules to generate harmless substances such as carbon dioxide and water, achieving the elimination of odor molecules. At the same time, bacteria and viruses will also have their cell walls and RNA directly damaged by the high-voltage electric field when passing through the discharge gap 700, and then be killed, so as to achieve a good effect of removing odors and purification.

[0066] In terms of structural arrangement, the grounding part 400 and the power supply part 500 are respectively arranged at both ends of the emission electrode assembly. When connecting, one end of some electrode components 600 is electrically connected to the power supply part 500, and one end is assembled to the grounding part 400. One end of some electrode components 600 is connected to the grounding part 400 for grounding, and one end is assembled to the power supply part 500. This not only realizes the support and fixation of the electrode component 600, but also realizes the integrated connection and assembly of multiple electrode components 600 with the grounding part 400 and the power supply part 500. The whole connection structure is not only compact but also simpler, making it more convenient to be assembled to positions such as the return air part or the air outlet part of the air conditioner during use, facilitating assembly and installation.

[0067] The electrode component 600 has a wiring terminal for electrical connection. When connecting, the wiring terminals of some electrode components 600 are connected to the power supply part 500, and the wiring terminals of some electrode components 600 are connected to the grounding part 400.

[0068] In some embodiments of the present application, referring to Figures 12-15 as shown, the electrode component 600 includes: an insulating dielectric shell 610 and a conductive component located inside the insulating dielectric shell.

[0069] In some embodiments of the present application, the insulating dielectric shell 610 is an insulating dielectric shell with a certain length. In some embodiments of the present application, the insulating dielectric shell 610 is made of quartz glass tube with good insulation.

[0070] In some embodiments of the present application, the outer diameter dimension of the insulating dielectric shell 610 is between 10 and 20 mm.

[0071] In some embodiments of the present application, the insulating dielectric shell 610 is made of materials such as ceramics, PTFE or nylon.

[0072] In some embodiments of the present application, the insulating dielectric shell 610 is an insulating dielectric tube with a tube orifice 616, which facilitates the assembly of the conductive component into it through the tube orifice 616.

[0073] In some embodiments of the present application, the conductive component includes: a conductive part 620.

[0074] The conductive part 620 is inserted into the insulating dielectric shell 610 from the tube orifice 616 along the axial direction of the insulating dielectric shell 610, and the assembly is convenient and fast.

[0075] In some embodiments of the present application, the inside of the conductive member 620 is hollow.

[0076] The hollow inside of the conductive member 620 can reduce the material usage, and the overall weight is relatively light, which reduces the overall weight of the electrode component 600 and lowers the production cost.

[0077] In some embodiments of the present application, a notch portion 621 extending along its axial direction is provided on the side wall of the conductive member 620. The notch portion 621 is configured to cause the conductive member 620 assembled inside the insulating dielectric shell 610 to deform radially to fit closely against the inner wall of the insulating dielectric shell 610.

[0078] The insulating dielectric shell 610 has poor dimensional accuracy during the high-temperature manufacturing process. Therefore, when the inner size of the insulating dielectric shell 610 is too small, if the dimensional accuracy of the conductive member 620 remains unchanged, it is difficult for the conductive member 620 to be inserted into the insulating dielectric shell 610.

[0079] In addition, since the low-temperature plasma electrode has strict requirements for the parallelism between the electrodes, non-parallel electrodes will cause uneven discharge between the electrodes. When the inner wall size of the insulating dielectric shell 610 is too large, the conductive member 620 will shake inside the insulating dielectric shell 610, resulting in the conductive member 620 not being able to fit completely against the inner wall of the insulating dielectric shell 610, causing the electrodes to be non-parallel.

[0080] The notch portion 621 axially provided along the conductive member 620 can communicate the notch portion 621 with the internal space of the conductive member 620, so that the conductive member 620 can deform through the notch portion 621.

[0081] During processing, wire cutting technology is used to extend the notch portion 621 in the axial direction of the conductive member 620, so that the conductive member 620 will undergo elastic deformation in the radial direction under the action of internal stress, causing the diameter of the conductive member 620 to become larger. At this time, the conductive member 620 with a notch has a certain elastic variable in the diameter direction.

[0082] When the actual inner diameter of the insulating dielectric shell 610 is larger than the reference inner diameter due to processing deviation, the conductive member 620 will expand along the radial direction, thereby ensuring that the outer wall of the conductive member 620 is adapted to the inner diameter of the insulating dielectric shell 610 and remains in contact with the inner wall of the insulating dielectric shell 610.

[0083] When the actual inner diameter of the insulating dielectric shell 610 is smaller than the reference inner diameter due to processing deviation, the conductive member 620 inserted inside it is compressed and deformed in the radial direction by the extrusion force of the inner wall of the insulating dielectric shell 610, and its size becomes smaller. Similarly, it ensures close contact with the inner wall of the insulating dielectric shell 610, thereby ensuring the parallelism and installation accuracy of the plasma electrode.

[0084] In some embodiments of the present application, the conductive member 620 is a metal member with conductivity, which can be used to ensure normal conduction of the electrode.

[0085] The conductive member 620 can be made of iron, copper, stainless steel, etc., which not only ensures conductivity but also has a certain hardness, so that it can be quickly and conveniently inserted into the interior of the insulating dielectric housing 610 during assembly to achieve its quick and convenient installation.

[0086] In some embodiments of the present application, the outer diameter of the conductive member 620 is less than 5% - 8% of the inner diameter of the insulating dielectric housing 610, and the wall thickness is less than 0.7 mm, so that the deformation amount in the diameter direction after its processing can meet the processing error requirements of the insulating dielectric housing 610.

[0087] In some embodiments of the present application, the outer diameter of the conductive member 620 is less than 5% of the inner diameter of the insulating dielectric housing 610.

[0088] In some embodiments of the present application, the outer diameter of the conductive member 620 is less than 6% of the inner diameter of the insulating dielectric housing 610.

[0089] In some embodiments of the present application, the outer diameter of the conductive member 620 is less than 8% of the inner diameter of the insulating dielectric housing 610.

[0090] In some embodiments of the present application, the wall thickness of the conductive member 620 is 0.1 mm.

[0091] In some embodiments of the present application, the wall thickness of the conductive member 620 is 0.3 mm.

[0092] In some embodiments of the present application, the wall thickness of the conductive member 620 is 0.5 mm.

[0093] In some embodiments of the present application, the wall thickness of the conductive member 620 is 0.6 mm.

[0094] When the conductive member 620 is in use, it should neither expand too much so that it cannot be effectively inserted into the insulating dielectric housing 610, nor expand too little, causing the conductive member 620 to shake inside the insulating dielectric housing 610. The outer diameter of the conductive member 620 is set to be less than 5% - 8% of the inner diameter of the insulating dielectric housing 610 to ensure that the conductive member 620 deforms within a suitable size range.

[0095] In some embodiments of the present application, the conductive assembly includes: a conductive connecting member 630, which is arranged inside the insulating dielectric housing 610, one end of which is connected to the conductive member 620 and the other end extends out of the insulating dielectric housing 610.

[0096] The conductive connecting member 630 is mainly used to achieve electrical connection for wiring, and it can be used to connect to the power supply unit 500 or the grounding unit 400.

[0097] In some embodiments of the present application, the conductive connecting member 630 is a conductive post, which is arranged side by side with the conductive member 620 in the insulating dielectric housing 610 and extends outward from the pipe orifice 616.

[0098] External threads 631 are provided on the extending section of the conductive connecting member 630 to facilitate the later wiring operation.

[0099] In some embodiments of the present application, referring to Figures 12-14 As shown, the conductive member 620 has a first end 623 and a second end 624 at its two ends, and the notch portion 621 extends from the first end 623 to the second end 624 along the axial direction of the conductive member 620.

[0100] The notch portion 621 is a long notch opened along the overall length direction of the conductive member 620.

[0101] The long notch is used to ensure that the conductive member 620 can deform along the radial direction at various positions in the entire length direction, ensure that each position of the conductive member 620 is in contact with the inner wall of the insulating dielectric housing 610, and ensure the parallelism and installation accuracy of the electrode component 600.

[0102] In some embodiments of the present application, the conductive member 620 is a conductive sleeve, and a first through hole and a second through hole are formed through both ends thereof, and the notch portion 621 extends from the first through hole to the second through hole.

[0103] In some embodiments of the present application, both ends of the conductive member 620 are not through, and hollowed portions are formed at positions corresponding to the notch portion 621 on the end faces of both ends of the conductive member 620 to ensure that the conductive member 620 can deform radially normally.

[0104] In some embodiments of the present application, the conductive member 620 has a first end 623 and a second end 624 opposite to the first end 623 formed at both ends.

[0105] In some embodiments of the present application, referring to Figure 18 As shown, the notch portion 621 includes a first deformation orifice portion 6211, which extends from the first end 623 of the conductive member 620 along the axial direction of the conductive member 620 towards the second end 624.

[0106] In some embodiments of the present application, the notch portion 621 includes a second deformation opening portion 6212. The second deformation opening portion 6212 and the first deformation opening portion 6211 are arranged staggeredly in the circumferential direction of the conductive member 620. The second deformation opening portion 6212 extends from the second end 624 of the conductive member 620 along the axial direction of the conductive member 620 towards the first end 623. One end of the second deformation opening portion 6212 far from the second end 624 is flush with one end of the first deformation opening portion 6211 far from the first end 623.

[0107] The first deformation opening portion 6211 and the second deformation opening portion 6212 arranged staggeredly constitute the notch portion 621 arranged along the axial direction of the conductive member 620.

[0108] The first deformation opening portion 6211 causes the conductive member 620 to deform on the section of the conductive member 620 corresponding to the first deformation opening portion. The second deformation opening portion can cause the conductive member 620 to deform on the section of the conductive member 620 corresponding to the second deformation opening portion 6212. Through the cooperation of the two, it can also ensure that the entire conductive member 620 deforms in the radial direction to fit and remain in contact with the inner wall of the insulating medium shell 610.

[0109] In some embodiments of the present application, referring to Figure 14 as shown, the conductive member 620 includes:

[0110] A sleeve body, with a first through portion 625 and a second through portion 626 formed at both ends thereof. The first through portion 625 and the second through portion 626 are communicated with the internal space of the sleeve body. The first through portion 625 is closer to the conductive connection member 630 than the second through portion 626.

[0111] The first through portion 625 is a first through opening, and the second through portion 626 is a second through opening. The two are communicated with the internal space of the sleeve body to form a conductive kit 5323.

[0112] A connecting portion 627 is formed around the first through portion 625. The connecting portion 627 extends along the axial direction of the insulating medium shell 610 to the conductive connection member 630 and is connected to the conductive connection member 630.

[0113] The first through portion 625 is close to the conductive connection member 630. By forming the connecting portion 627 around the first through portion 625, the connection with the conductive connection member 630 can be achieved at a relatively short distance.

[0114] The connection between the connecting portion 627 and the conductive connection member 630 ensures the continuity of the electrical transmission path and the transmission of electricity.

[0115] In some embodiments of the present application, a plurality of connection portions 627 are provided and arranged circumferentially along the first through portion 625. The connection of the plurality of connection portions 627 to the conductive connection member 630 ensures the firmness of the connection.

[0116] During molding, a part can be cut out from the middle at one end of the conductive member 620 by wire cutting, so that one connection portion 627 is left on each side, and the two connection portions 627 are symmetrically distributed on both sides of the notch portion 621.

[0117] In some embodiments of the present application, with reference to Figure 14 as shown, the connection portion 627 includes:

[0118] An inclined connection arm 6271, which is inclined from the conductive member 620 towards the conductive connection member 630, and is used to realize the transition of the connection from the conductive member 620 to the conductive connection member 630.

[0119] A straight connection arm 6272, which is connected to the inclined connection arm 6271, fits against the outer wall of the conductive connection member 630 and is welded and fixed thereto. The straight connection arm 6272 can be welded and fixed to the outer side wall of the conductive connection member 630 to realize the connection with the conductive connection member 630.

[0120] During connection, the conductive connection member 630 is inserted into the middle position of the plurality of connection portions 627, and the plurality of connection portions 627 are welded to the conductive connection member 630 simultaneously by spot welding.

[0121] In some embodiments of the present application, with reference to Figures 16-17 as shown, a protruding positioning protrusion portion 613 is formed on the inner wall of the insulating dielectric shell 610, and is used to be inserted into the notch portion 621 to guide and position the installation of the conductive member 620.

[0122] After the conductive member 620 is processed with the notch portion 621, there is no conductive substance at the notch portion 621. Therefore, plasma discharge cannot be performed at the notch portion 621. When arranging multiple plasma electrode components 600, the notch portion 621 cannot be facing another plasma electrode component 600. Therefore, it is necessary to position the notch portion 621.

[0123] Through the positioning protrusion portion 613 designed at a specific position inside the insulating dielectric shell 610, when installing the conductive member 620, the notch portion 621 is aligned with the positioning protrusion portion 613, and the conductive member 620 is inserted into the insulating dielectric member. The positioning protrusion portion 613 guides the notch portion 621, so that all the notch portions 621 can be inserted into the insulating dielectric shell 610 along the same direction, and the notch portions 621 of multiple electrode components 600 all face one direction.

[0124] In some embodiments of the present application, the insulating dielectric housing 610 has a first connection end 614, and a limiting protrusion 612 for positioning its assembly position to the power supply part 500 or the grounding part 400 is provided on the insulating dielectric housing 610 near the first connection end 614.

[0125] During assembly, the insulating dielectric housing 610 is inserted into the power supply part 500 or the grounding part 400, and its insertion position can be limited by the limiting protrusion 612, so that it can be quickly assembled in place.

[0126] The insulating dielectric housing 610 includes a second connection end 615, and a threaded connection part 611 for connecting and cooperating with the grounding part 400 or the power supply part 500 is formed at the second connection end 615.

[0128] In some embodiments of the present application, as shown in Figure 12 shown, it includes a fixed sealing assembly, including:

[0129] A blocking member 640 is assembled in the insulating dielectric housing 610 and is located at a position between the second connection end 615 and the conductive member 620.

[0130] The blocking member 640 is a plug, which mainly plays a sealing role, and the plug has a certain length to increase the creepage distance of the electrode component 600 during use and improve safety. The pipe wall of the insulating dielectric housing 610 and the plug are connected by high-temperature welding. The pipe wall thickness should be between 1 and 1.5 mm.

[0131] During assembly, the conductive member 620 is mainly inserted into the insulating dielectric housing 610 from the pipe orifice 616 until the conductive member 620 contacts the bottom plug.

[0132] A seal 650 is inserted into the insulating dielectric housing 610 and is sleeved at the connection position of the conductive member 620 and the conductive connection member 630. The seal 650 is a sealing rubber plug.

[0133] After the conductive member 620 is inserted to the bottom of the insulating dielectric member, the seal 650 is pushed into the insulating dielectric housing 610 by a ring-shaped tooling until the welding position of the conductive member 620 and the conductive connection member 630. Its main function is to prevent the sealing filler in the subsequent process from flowing into the inside of the conductive member 620.

[0134] The sealing filler is filled in the insulating dielectric housing 610 and is in the area between the seal 650 and the first connection end 614.

[0135] The sealing filler is an epoxy resin sealant. The epoxy resin sealant is poured into the remaining space of the insulating medium shell 610 and leveled with the pipe orifice 616. After the curing is completed, the assembly of the electrode component 600 is completed.
