Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air purification device that can be infinitely spliced ​​together. Background Technology

[0002] Traditional air purifiers typically use an external electrical box design, placing it on the outer frame of the device. This not only occupies a significant amount of space above the frame, limiting the compactness and flexibility of the air purifier, but also easily leads to electrical safety issues. Furthermore, the wiring connectors in existing devices often occupy space in the width direction, resulting in an excessively wide outer frame for the purifier. This not only increases material costs but also reduces the effective purification area and efficiency per unit space.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an air purification device that can be infinitely spliced ​​together, so as to solve the technical problems in the related technology where the internal structure layout of the air purification device is unreasonable, resulting in limited splicing flexibility and low effective purification area.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: It provides an air purification device that can be infinitely spliced, comprising: an outer frame and a purification component detachably disposed within the outer frame. The purification component purifies the air through ionization and dust collection. An electrical box is disposed inside the outer frame, rotatably disposed relative to the outer frame. The electrical box is correspondingly disposed with the high-voltage power supply of the purification component, and the power lines of the high-voltage power supply and the electrical box are connected to an external power source. Multiple sides of the outer frame are provided with splicing plates, which extend vertically outward from the sides of the outer frame for splicing and installation with the outer frames of adjacent air purification devices, thereby achieving splicing from multiple directions.

[0006] Furthermore, the outer frame includes a first frame plate, a second frame plate, a third frame plate, and a bottom plate. The first frame plate, the second frame plate, the third frame plate, and the bottom plate are connected in sequence to enclose the purification component inside the outer frame. The electrical box is arranged below the second frame plate. The first frame plate and the third frame plate are arranged opposite each other, and the second frame plate and the bottom plate are arranged opposite each other. The splicing plate is connected to the first frame plate, the second frame plate, and the third frame plate respectively.

[0007] Furthermore, the outer frame is provided with perforations, and a fourth frame plate is vertically connected to one side of the second frame plate. The perforations are set on the fourth frame plate, and the power lines of the high-voltage power supply and the electrical box pass through the perforations to connect with the external power supply. The splicing plate connecting the fourth frame plate and the second frame plate is on the same plane.

[0008] Furthermore, the electrical box is fixed on the support frame. The first and third frame plates are respectively provided with rotating holes. The support frame is connected to the outer frame through the rotating holes so that the support frame can drive the electrical box to rotate relative to the outer frame. The fourth frame plate is provided with two mounting holes. One end of the electrical box is hinged to the outer frame, and the other end is fixed to the fourth frame plate by fasteners passing through the mounting holes.

[0009] Furthermore, there are at least two sets of purification components, with each set of purification components arranged sequentially along the length extension direction of the second frame plate.

[0010] Furthermore, a baffle is also provided on the outer frame. One end of the baffle is connected to the second frame plate, and the other end of the baffle is connected to the bottom plate. The baffle is correspondingly set at the connection points of the two adjacent purification components to seal the gap between the two adjacent purification components.

[0011] Furthermore, each purification component includes a dust collection module and an electric field module. The dust collection module is located between the electric field module and the baffle. The electric field module is equipped with a support component. One end of the support component is connected to the discharge rod of the electric field module, and the other end is connected to the conductive plate of the electric field module. This support component is used to support the conductive plate and prevent it from deforming during ionization.

[0012] Furthermore, there are multiple support components, which are spaced apart. Each support component includes a support column and a buckle. The buckle is snapped onto the discharge rod, and the support column is vertically connected to the buckle, thereby supporting the conductive plate.

[0013] Furthermore, the diameter of the support post near the conductive plate is larger than the diameter of the support post near the discharge rod to increase the creepage distance.

[0014] Furthermore, a first limiting plate is also provided on the base plate. The first limiting plate is correspondingly provided to each group of purification components. The first limiting plate includes a first fixing plate and a first abutting plate. The first fixing plate and the first abutting plate are vertically connected to form an L-shaped structure. The first fixing plate is attached to the base plate. When the purification component is placed inside the outer frame, the first abutting plate abuts against the purification component to prevent the purification component from moving.

[0015] Furthermore, the air purifier is also equipped with a pre-filter, which is clipped into the outer frame and located between the fourth frame plate and the purification component, and is used to filter out hair and large particles in the air.

[0016] Beneficial effects:

[0017] 1. By embedding the high-voltage power supply within the inner frame of the purification component and setting a compact electrical box within the outer frame, the overall space of the equipment is effectively saved; the layout of the equipment is optimized, improving the compactness and installation flexibility of the air purification device, making it suitable for various space-constrained scenarios.

[0018] 2. The design of the splicing panels and splicing holes enables splicing in multiple directions, allowing multiple air purification devices to be flexibly combined according to different needs.

[0019] 3. The design of the support components prevents the conductive plate from deforming during ionization, extends the discharge distance between the conductive plate and the discharge rod, and reduces the risk of creepage.

[0020] 4. The built-in electrical box and optimized wiring layout reduce the width of the outer frame, saving materials and increasing the effective purification area per unit space.

[0021] 5. The grounding component design directly grounds the conductive plate, ensuring reliable charge discharge and improving the safety and stability of equipment operation; the grounding bead combined with the elastic component design ensures a stable connection between the field power module and the outer frame during installation, and completes the reliable grounding function through the grounding bead; the elasticity of the elastic connector alleviates possible errors during the assembly of the purification components, improving the fault tolerance of the equipment during installation.

[0037] 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.

[0038] According to an embodiment of this utility model, an air purification device that can be infinitely spliced ​​is provided. Please refer to [link / reference]. Figures 1 to 13 The system includes an outer frame 1 and a purification component 2 detachably mounted within the outer frame 1. The purification component 2 purifies the air through ionization and dust collection. An electrical box 11 is housed inside the outer frame 1 and is rotatably mounted relative to the outer frame 1. The electrical box 11 corresponds to the high-voltage power supply 22 of the purification component 2, and the power lines of the high-voltage power supply 22 and the electrical box 11 are connected to an external power source. Multiple sides of the outer frame 1 are equipped with splicing plates 81, which extend vertically outward from the sides of the outer frame 1 for splicing and installation with the outer frames 1 of adjacent air purification devices, enabling splicing from multiple directions. The purification component 2 is detachably mounted within the outer frame 1, allowing for easy removal and replacement when it malfunctions or requires maintenance, eliminating the need to disassemble the entire air purification device and reducing maintenance costs and time. The high-voltage power supply 22 is built into the inner frame 21, avoiding the space-consuming problem caused by the external mounting of the traditional electrical box, making the air purification device more compact. The connection between the high-voltage power supply 22 and the electrical box 11 must ensure good electrical isolation and insulation to prevent safety hazards caused by high-voltage leakage. The inner frame 21 of the purification assembly 2 has a first interface 23 for exposing the two positive and negative electrical contact pieces 221 of the high-voltage power supply 22, and the electrical box 11 has a second interface. The corresponding arrangement of the first and second interfaces allows the electrical contact pieces 221 to easily achieve electrical connection, ensuring a more stable electrical connection between the electrical contact pieces 221 and the electrical box 11, effectively reducing the safety risks caused by exposed electrical contact parts. The high-voltage power supply 22 is built into the purification assembly 2, reducing the chance of particulate matter adhesion and reducing creepage caused by decreased surface resistance. Multiple sides of the outer frame 1 have splicing plates 81 with splicing holes 82. In the horizontal direction of the outer frame, the splicing plates 81 on one side of the outer frame fit together with the splicing plates 81 on another side of the outer frame. Fasteners pass through the splicing holes 82 on the two splicing plates 81 in sequence to achieve horizontal splicing of multiple air purification devices. In the vertical direction of the outer frame, the outer frames of two adjacent air purification devices are joined together by splicing plates 81. Fasteners pass through the splicing holes on the plates to achieve longitudinal splicing of multiple air purification devices. The splicing plates 81 extend vertically outward from the side of the outer frame 1, making the device assembly structure compact and further increasing the purification area. The infinitely splicable air purification device of this embodiment solves the technical problem in related technologies where the internal structural layout of air purification devices is unreasonable, resulting in limited splicing flexibility and a low effective purification area.

[0039] See Figure 1 , Figure 2 and Figure 3This embodiment of the air purification device, which can be infinitely spliced, has an outer frame 1 comprising a first frame plate 13, a second frame plate 14, a third frame plate 15, and a bottom plate 16. The first frame plate 13, second frame plate 14, third frame plate 15, and bottom plate 16 are sequentially connected to enclose the purification component 2 within the outer frame 1. An electrical box 11 is positioned below the second frame plate 14 so that the second interface corresponds to and connects with the first interface 23. The first frame plate 13 and third frame plate 15 are positioned opposite each other, as are the second frame plate 14 and bottom plate 16. Splicing plates 81 are respectively connected to the first frame plate 13, second frame plate 14, and third frame plate 15. A high-voltage power supply 22 is located at the top of the inner frame 21. The electrical box 11 is positioned below the second frame plate 14 and corresponds to and connects with the first interface 23. This layout not only makes the internal structure of the air purification device more compact but also effectively utilizes the vertical space inside the device, reducing the overall volume and improving space utilization. The splicing panels 81 are connected to the first frame panel 13, the second frame panel 14 and the third frame panel 15 respectively, so as to achieve splicing of the left and right sides and the top of the outer frame 1.

[0040] See Figure 1 , Figure 2 and Figure 3 The air purification device of this embodiment can be infinitely spliced. The outer frame 1 is provided with a perforation 12. A fourth frame plate 17 is vertically connected to one side of the second frame plate 14. The perforation 12 is set on the fourth frame plate 17. The power line of the high voltage power supply 22 electrical box 11 passes through the perforation 12 and is connected to the external power supply. The splicing plate 81 connecting the fourth frame plate 17 and the second frame plate 14 is on the same plane.

[0041] The fourth frame plate 17 is the side facing the airflow, which is the frontal view angle of the air purification device. The perforation 12 is set on the fourth frame plate 17 to facilitate the neat exit of the power line and connection to the external power source, and also to facilitate the maintenance and replacement of the line.

[0042] See Figure 2In the air purification device of this embodiment, the electrical box 11 is fixed to the support frame 114. The first frame plate 13 and the third frame plate 15 are respectively provided with rotating holes 111, through which the support frame 114 is connected to the outer frame 1, allowing the support frame 114 to rotate the electrical box 11 relative to the outer frame 1. The fourth frame plate 17 is provided with two mounting holes 112. One end of the electrical box 11 is hinged to the outer frame 1, and the other end is fixed to the fourth frame plate 17 by fasteners passing through the mounting holes 112. The support frame 114 of the electrical box 11 is manufactured using a one-piece molding process. Rotating holes 111 are provided on both sides of the outer frame 1, through which the support frame 114 is connected to the outer frame 1, allowing the support frame 114 to rotate relative to the outer frame 1. The fourth frame plate 17 has two mounting holes 112. One end of the electrical box 11 is hinged to the rotation hole 111 of the outer frame 1, and the other end is fixed to the fourth frame plate 17 by two fasteners passing through the frame and the mounting holes 112. When the electrical box 11 needs maintenance, the fasteners on the mounting holes 112 can be removed to suspend the support frame 114 inside the outer frame for easy maintenance. This design effectively supports the electrical box 11 and greatly reduces the complexity of the assembly process. The frame design has a rotation function and can rotate flexibly relative to the outer frame 1, so that operators can easily access the electrical box 11 by simply rotating the frame without disassembling the entire electrical box, thus greatly facilitating subsequent maintenance and repair work.

[0043] See Figure 3 The electrical box 11 is equipped with a pull-down movable card 113. After the dust collection module and the field power module are installed, the field power module can be directly fixed by pulling down the movable card 113, so that the field power module and the dust collection module are both confined within the outer frame 1 of the purification device. Depending on the design, the field power module and the dust collection module can also be designed with movable buckles.

[0044] See Figure 3The splicing plate 81 is perpendicular to the first frame plate 13 and the third frame plate 15, forming an outwardly extending L-shaped structure, which enables rapid splicing between individual air purification devices. For example, in the purification section of an air conditioning unit, a vertically placed purification device and a horizontally placed purification device can be quickly spliced ​​together using the L-shaped structure, significantly reducing on-site installation time. Each splicing plate with splicing holes also features bent edges to increase the connection strength. After installation, the L-shaped structure effectively covers uncovered areas or edge spaces, improving overall sealing. Standard L-shaped components, included with the product, can be quickly connected to the purification device frame and fixed to the inner frame of the air conditioning unit for convenient installation. Furthermore, the male and female quick-connect couplings on both sides of the front further simplify the installation and maintenance process. Each device has interconnectable quick-connect couplings on the left and right sides, allowing for rapid electrical connection and assembly. The front-mounted quick-connect couplings also avoid the problem of occupying space in the width direction of the purification device due to side-mounted couplings. This layout design makes the frame of the purification device narrower, providing more usable space for the field electrostatic module, dust collection module and pre-filter module, thereby significantly improving purification efficiency and dust capacity per unit space.

[0045] An air purification device can be assembled from a set of purification components 2 (such as...) Figure 1 (As shown), it can also be composed of two sets of purification components 2 (as shown). Figure 4 , Figure 5 and Figure 6 As shown, each group of purification components 2 is arranged sequentially along the length of the second frame plate 14. Of course, there can be three or more groups of purification components; increasing the number of purification components can significantly improve the purification efficiency of the air purification device. Each group of purification components can independently perform ionization and dust collection operations, thereby collectively enhancing the overall air purification capacity. The sequential arrangement of the purification components 2 along the extension direction of the second frame plate 14 utilizes the longitudinal space inside the outer frame 1, facilitating assembly and making the device more neat and aesthetically pleasing.

[0046] The purification component 2 includes a dust collection module 24 and an electrostatic module 25. The dust collection module 24 includes a micro-electrostatic module, or it can be a plate-type electrostatic dust collection module. Plate-type electrostatic dust collection modules have various forms: A plate-type electrostatic dust collection module uses staggered dust collection plates, with an insulator in the middle and conductive materials on both sides, bonded together with adhesive. Adjacent dust collection plates are supplied with voltages of different potentials. Alternatively, a plate-type electrostatic dust collection module can also use staggered dust collection plates, with an insulating layer in the middle, semiconductor layers on both sides, and a conductive layer located between the semiconductor and insulating layers, bonded together with adhesive. Adjacent dust collection plates are supplied with voltages of different potentials. The dust collection plates of the plate-type electrostatic dust collection module can have ports to avoid adhesive residue. During production, dust collection plates with the same potential are fixed together, ensuring sufficient spatial distance between dust collection plates with different potentials. The plate-type electrostatic dust collection module can also use conductive plastic to make the dust collection plate, or a dust collection plate in the form of insulating material wrapped around conductive material. The dust collection plate is fixed by glue or by a limiting structure to keep dust collection plates with different potentials at the same distance, ensuring a stable electric field and guaranteeing air purification efficiency. This embodiment uses the micro electrostatic module 241 as an example; other dust collection modules such as the plate-type electrostatic dust collection module are similar.

[0047] The micro-electrostatic module 241 uses a dielectric material to encapsulate a conductive material, forming a flat, dense microcavity MESP dust collection module. Different potential voltages are applied to adjacent conductive materials to create an electric field, which captures charged particles as they pass through. The field electrostatic module 25 uses needle tip discharge, applying a positive or negative DC high voltage. A circular or near-circular hole is formed in the ground plane, and the needle tip and negative electrode plate create an ionization region, causing airborne particles to become charged as they pass through.

[0048] The air purification device of this embodiment, which can be infinitely spliced, is also provided with a baffle 5 on the outer frame 1. One end of the baffle 5 is connected to the second frame plate 14, and the other end of the baffle 5 is connected to the bottom plate 16. The baffle 5 is correspondingly set at the connection point of two adjacent purification components 2 to seal the gap between the two adjacent purification components 2. Figure 4 This is a diagram showing two micro-electrostatic modules 241 arranged side-by-side along the length of the second frame plate 14 in use. Figure 5 This is a diagram showing two field electrostatic modules 25 arranged side-by-side along the length of the second frame plate 14. In actual use, three, five, or more modules can also be arranged side-by-side, with each column of micro electrostatic modules 241 and field electrostatic modules 25 forming a purification component 2. Figure 6This diagram shows the usage state of two sets of purification components 2 arranged side by side. The baffle 5 directly seals the gap between two adjacent purification components 2, effectively preventing unfiltered air or particulate matter from escaping through these gaps, thus significantly improving the airtightness of the air purifier. A sealing strip is installed on the baffle 5 to further enhance the sealing effect. The sealing strip is soft and elastic, able to tightly fit the tiny gaps between the purification components, ensuring no leakage. Due to the presence of the baffle 5 and the sealing strip, particulate matter cannot escape at the junction, thus ensuring that the air inside the air purifier flows through each purification component for thorough purification. This helps improve purification efficiency and ensures the quality of the output air.

[0049] See Figure 7 When a single purification component 2 is used, that is, only one set of micro electrostatic module 241 and field electric module 25, there is no need to use the baffle 5. It is only necessary to prevent the gap between the outer frame 1 and the purification component 2.

[0050] See Figure 6 This embodiment of the infinitely combinable air purification device employs dual purification components 2. Each purification component 2 includes a dust collection module 24 and an electric field module 25. The dust collection module 24 is located between the electric field module 25 and the baffle 5. A support component 3 is provided on the electric field module 25. One end of the support component 3 is connected to the discharge rod 251 of the electric field module 25, and the other end is connected to the conductive plate 252 of the electric field module 25, used to support the conductive plate 252 and prevent it from deforming during ionization. The discharge rod 251 generates a strong electric field through a high-voltage power supply, ionizing the air and charging neutral air molecules to form charged particles. The conductive plate 252, as the other pole of the electric field, purifies the air by adsorbing charged particles. The electric field strength between the discharge rod and the conductive plate determines the ionization efficiency and purification effect. The high-voltage electric field will generate an electric field force on the conductive plate 252, and the mechanical vibration during equipment operation may cause the conductive plate 252 to deform. Deformation of the conductive plate 252 will affect the uniformity of the electric field, reduce ionization efficiency, and may also lead to electrical faults such as creepage or arcing. The support assembly 3 stabilizes the conductive plate 252, preventing it from deforming under the influence of the electric field, ensuring a uniform electric field distribution, improving purification efficiency, and extending the service life of the equipment.

[0051] See Figure 1 and Figure 8The field power module 25 uses low-voltage power supply, while the high-voltage power supply is built into the upper part of the field power module 25 and is completely sealed. This sealing includes two parts: one part is that the high-voltage power supply body is completely sealed, so even if there is residual water at the upper part, it will not affect normal use; the other part is that the cavity at the upper part where the high-voltage power supply is placed is semi-sealed, with drainage holes only at the bottom, so that water can flow out naturally after cleaning and accelerate drying. Similar to the field power module 25, the dust collection module adopts a similar sealing method. The difference is that the dust collection module only retains space for the high-voltage line routing. The dust collection module can be provided with drainage holes at the bottom and sides to accelerate its internal drying. The module is designed with a reverse connection protection device, and the low-voltage power supply electrode plates are asymmetrically designed to prevent customers from installing them backwards, which would cause the module to malfunction.

[0052] See Figure 8 and Figure 9 This embodiment of the air purification device allows for unlimited splicing. Multiple support components 3 are spaced apart. Each support component 3 includes a support column 31 and a buckle 32. The buckle 32 engages with the discharge rod 251, and the support column 31 is vertically connected to the buckle 32, thus supporting the conductive plate 252. A groove 321 is provided within the buckle 32, which engages the discharge rod 251, thereby extending the discharge distance between the discharge rod 251 and the conductive plate 252 and preventing creepage. The diameter of the end of the support column 31 near the conductive plate 252 is larger than the diameter of the end of the support column 31 near the discharge rod 251 to increase the creepage distance. A high-voltage electric field is formed between the discharge rod 251 and the conductive plate 252. The conductive plate 252 serves as the negative electrode of the high-voltage electric field and needs to be kept flat and fixed to avoid abnormal electric field distribution due to vibration or deformation. The spaced support design of the support column 31 for the conductive plate 252 can disperse the stress on the conductive plate and prevent local deformation due to concentrated stress points. The snap-fit ​​32 directly snaps onto the discharge rod 251, making the connection of the support assembly 3 quicker. The design of the groove 321 effectively extends the creepage path. The threaded ring 311 on the support column 31 not only provides a larger contact area and indirectly increases the creepage path, but also increases the mechanical strength between the conductive plate and the support assembly 3. The position of the larger diameter component near the conductive plate 252 provides greater strength and installation space, while the position of the smaller diameter component near the discharge rod 251 reduces the width of the insulating surface, thereby increasing the creepage distance per unit space and improving electrical safety.

[0053] See Figure 10This embodiment features an infinitely combinable air purification device. The device also includes a primary filter 6, which is snapped into the outer frame 1 and located between the fourth frame plate 17 and the purification component 2. This primary filter filters out large particulate impurities from the air. A safety switch and an electrical switch button are designed on the side of the outer frame 1 facing the airflow, facilitating installation and maintenance. The safety switch utilizes the height space of the electrical box and is embedded in the bent side of the electrical box. A mounting hole for the safety switch is provided on the side, and a limit switch is located behind the safety switch. When the safety switch is compressed, the circuit remains connected; when the safety switch is not compressed, the circuit is disconnected. When the frame of the primary filter 6 compresses the safety switch, the device's circuit remains connected. During maintenance, opening the primary filter 6 automatically cuts off the power to the device, thus preventing electric shock accidents caused by forgetting to disconnect the power and directly opening the device. By utilizing the height space of the electrical box through a safety switch, not only can secondary safety protection of the equipment be achieved, but integrating the safety switch within the electrical box also saves space and increases the effective purification area of ​​the primary filter 6 per unit space. This improves the stability of airflow in the purification device, as well as its dust holding capacity and efficiency. The primary filter can be a traditional media filter or... Figure 1 The nylon mesh 61 shown Figure 10 The V-shaped folded metal mesh 62 is shown. If the pre-filter is relatively large, supports should be added between the pre-filters to maintain strength during operation and prevent deformation. Adding sealing strips to the frame of the pre-filter can ensure that large particles such as mosquitoes in the air are effectively intercepted.

[0054] See Figure 11 In this embodiment, the air purification device, which can be infinitely spliced, also includes a first limiting plate 41 on the base plate 16. The first limiting plate 41 corresponds to each purification component 2 and includes a first fixing plate 411 and a first abutting plate 412. The first fixing plate 411 and the first abutting plate 412 are vertically connected to form an L-shaped structure. The first fixing plate 411 is attached to the base plate 16. When the purification component 2 is placed inside the outer frame 1, the first abutting plate 412 abuts against the purification component 2, thereby preventing the purification component 2 from moving. As an additional structure on the base plate 16, the first limiting plate 41 not only serves a limiting function but also enhances the overall structural strength of the device. When the device is running or subjected to external impact, when the purification component 2 is placed inside the outer frame 1, the first abutting plate 412 tightly abuts against the purification component 2, effectively preventing the purification component from moving or shaking during device operation. The first limiting plate 41 can effectively disperse and bear some of the force, thereby protecting the base plate 16 and the purification components from damage.

[0055] See Figure 11In this embodiment, the air purification device, which can be infinitely spliced, also includes a second limiting plate 42 on the base plate 16. The second limiting plate 42 includes a second fixing plate 421 and a second abutting plate 422. The second fixing plate 421 and the second abutting plate 422 are vertically connected to form an L-shaped structure. The second fixing plate 421 is attached to the base plate 16, and the second abutting plate 422 abuts against the primary filter 6 to prevent the primary filter 6 from moving. The plane where the first abutting plate 412 is located is parallel to the plane where the second abutting plate 422 is located, and the distance between them is equal to the distance between the primary filter 6 and the purification component 2. The second abutting plate 422 abuts tightly against the primary filter 6, effectively preventing the primary filter from shifting or shaking during operation. The first abutting plate 412 and the second abutting plate 422 are arranged in parallel, and the distance between them is exactly equal to the distance between the primary filter 6 and the purification component 2. This design not only controls the position between each module and avoids misinstallation, but also ensures the close cooperation between each component and optimizes the internal spatial layout of the air purification device, making the entire device compact, beautiful and efficient.

[0056] See Figure 12 and Figure 13 This embodiment of the air purification device allows for unlimited splicing. The device also includes a grounding component 7, which comprises a grounding bead 71, a through hole 72, and an elastic connector 73. The elastic connector 73 is located within the outer frame 1 and is connected to the grounding bead 71. The through hole 72 is located on the field electric module 25. Under the elastic force of the elastic connector 73, the grounding bead 71 moves along the inner side of the outer frame 1 and springs into the through hole 72, connecting the field electric module 25 to the outer frame 1. One end of a wire is connected to the grounding bead 71 through the through hole 72, and the other end is connected to the conductive plate 252, directly grounding the conductive plate 252. This allows the charge to be directly discharged to the ground during ionization. Traditional air purification devices require high-voltage power supplies and complex circuits to handle the charge. This design, through the direct grounding of the grounding bead 71 and the conductive plate 252, allows the negative charge generated during ionization to be quickly and safely discharged to the ground, avoiding the risk of electric shock or equipment damage that may be caused by charge accumulation. Furthermore, directly discharging the negative charge through the grounding component 7 reduces the complexity of the circuit design and lowers manufacturing and maintenance costs. The design of the elastic connector 73 ensures the stability and contact reliability of the grounding bead 71. The design of the grounding bead 71 moving along the inner side of the outer frame 1 makes assembly and disassembly more convenient and adaptable to modular structures. The elasticity provided by the elastic connector 73 ensures that the grounding bead 71 forms a stable electrical connection between the outer frame 1 and the field electric module 25, maintaining good conductivity even during equipment operation with vibration or displacement.

[0057] like Figure 13As shown, the elastic connector 73 is a spring, fixed in the bottom cylinder 74 with holes at both ends. The bottom cylinder 74 can be embedded in the mounting hole 161 of the outer frame bottom plate 16, or it can be set on other frame plates. The grounding bead 71 can ensure that the conductive plate 252 of the field electric module 25 can be tightly connected to the outer frame 1 of the purification device, regardless of whether it is placed vertically, horizontally, or at other angles, to prevent charge accumulation. The grounding bead 71 can be designed as one or more, and after installation, due to elastic deformation, it generates elastic force, so that the outer frame 1 and the field electric module 25 maintain tight contact.
