Electrostatic technology, with its high efficiency and low energy consumption, has gradually become one of the mainstream technologies in the air purification field. This technology mainly achieves air purification through the coordinated operation of an ionization zone and a dust collection zone: First, in the ionization zone, high voltage is used to ionize air molecules, generating charged particles; subsequently, these charged particles are attracted by a strong electric field in the dust collection zone and deposited on the dust collection plate, thereby effectively removing fine particulate matter in the air, such as dust, pollen, and bacteria.

A reasonable electrical safety distance needs to be designed to ensure electrical safety.

[0004] Therefore, existing technologies still need further development. Utility Model Content

[0026] 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.

[0027] Please see Figures 1 to 6 According to an embodiment of this utility model, a novel air purification device for air conditioning return air is provided, comprising: a housing 1, an energy conversion component 2, a purification component 3, a first conductive element, and a second conductive element 4. The housing 1 has a first placement cavity and a second placement cavity; the first placement cavity is located above the second placement cavity; the energy conversion component 2 is disposed in the first placement cavity; the energy conversion component 2 is used to be electrically connected to an external power source, and the energy conversion component 2 is used to convert the electrical energy input from the external power source into target electrical energy; the purification component 3 is disposed in the second placement cavity; the purification component 3 has a power supply unit, which is used to be electrically connected to the energy conversion component 2; the first conductive element and the second conductive element 4 are detachably connected, and the end of the first conductive element away from the second conductive element 4 is connected to the energy conversion component 2, and the end of the second conductive element 4 away from the first conductive element is connected to the power supply unit; the energy conversion component 2 is electrically connected to the power supply unit through the first conductive element and the second conductive element 4.

[0028] As can be seen, the novel air purification device for air conditioning return air provided by this utility model includes a housing 1, an energy conversion component 2, a purification component 3, a first conductive element, and a second conductive element 4. The housing 1 has a first placement cavity and a second placement cavity. The energy conversion component 2 is disposed in the first placement cavity and is electrically connected to an external power source. Simultaneously, the output end of the energy conversion component 2 is electrically connected to the power supply of the purification component 3 through the first and second conductive elements 4. The energy conversion component 2 converts the electrical energy input from the external power source into target electrical energy and delivers the converted electrical energy to the power supply of the purification component 3. The purification component 3 is used to purify the air. Furthermore, the first conductive element and the second conductive element 4 are detachably connected. Therefore, the detachable connection design of the first and second conductive elements allows users to periodically clean or replace the conductive elements, effectively avoiding the degradation of electrical performance caused by particulate matter accumulation. Moreover, compared to fixed electrolytic contacts, detachable conductive elements allow for more flexible adjustment of contact pressure, ensuring good electrical contact and reducing safety hazards such as arc discharge caused by poor contact. Meanwhile, the detachable connection between the first conductive component and the second conductive component 4 not only facilitates maintenance but also ensures a stable and reliable electrical connection during normal use, avoiding the risk of accidental short circuits or electric shocks caused by poor contact. Furthermore, by placing the power conversion component 2 and the purification component 3 respectively within the first and second placement cavities of the housing 1, effective isolation of the electrical components is achieved, reducing the possibility of direct contact between the user and high-voltage parts and greatly improving safety during use. Therefore, this novel air conditioning return air purification device solves the technical problem in existing air purification devices where the purification module uses electrolytic contacts as the electrical connection between the purification module and the power conversion module.

[0029] Specifically, such as Figure 2 As shown, the first conductive component includes a first wire and a first connector, with the first wire connected to the power conversion component 2 and the first connector respectively. The second conductive component 4 includes a second wire 41 and a second connector 42, with the second wire 41 connected to the power supply unit and the second connector 42 respectively. The end of the second connector 42 away from the second wire 41 is threadedly connected to the end of the first connector away from the first wire. With this structural arrangement, the first connector and the second connector 42 establish a power transmission path through a threaded connection. Compared to traditional electrolytic contact methods, threaded connections have a larger contact area and a tighter connection, effectively reducing contact resistance and improving conductivity, thereby ensuring the stability of the electrical connection between the power conversion component 2 and the purification component 3. Furthermore, the threaded connection allows for control of contact pressure through tightening force, avoiding poor contact caused by vibration, dust accumulation, or oxidation, significantly reducing the risk of electrical faults such as arcing and short circuits during operation.

[0030] Furthermore, the first and second connectors 42 adopt an embedded axial mating structure, specifically as follows: an external thread is provided on the circumferential sidewall of the first connector; correspondingly, an insulating protective sleeve is coaxially fitted on the mating end of the second connector 42, and the inner wall of the insulating protective sleeve has an internal thread structure that mates with the external thread. During electrical connection, the first connector is axially inserted into the second connector 42, and then the insulating protective sleeve is rotated to engage the internal and external thread structures, thereby achieving axial compression and locking of the connectors.

[0031] The specific structures of the first and second connectors 42 can be interchanged or replaced according to actual application requirements. For example, in some application scenarios, an external threaded portion can be provided on the circumferential sidewall of the second connector 42, while an insulating protective sleeve with an internal threaded structure can be coaxially fitted on the mating end of the first connector. This flexible design allows the connectors to adapt to different installation conditions and maintenance requirements, further improving the versatility and practicality of the system.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the housing 1 includes: a frame 11, the frame 11 having a placement space 10; an inspection cover 12, the inspection cover 12 being rotatably mounted on the frame 11, the inspection cover 12 having a support portion and a sealing portion connected to each other, the support portion being disposed within the placement space 10, the support portion dividing the placement space 10 into a first placement cavity and a second placement cavity; the sealing portion sealing the first placement cavity; wherein, the support portion having a first clearance groove 120 on the side facing the second placement cavity, and the first clearance groove 120 being located on the side of the inspection cover 12 near the inner wall of the frame 11; the top end of the purification component 3 having a second clearance groove 30, the second clearance groove 30 being disposed opposite to the first clearance groove 120, so that when the purification component 3 is installed in the second placement cavity, the first clearance groove 120, the frame 11, and the second clearance groove 30 form a clearance cavity; at least a portion of the first conductive element and the second conductive element 4 are located within the clearance cavity.

[0033] This structural design, featuring an inspection cover 12 rotatably mounted on the frame 11 and comprising a support and a sealing section, allows users to easily access the power conversion component 2 and other electrical components within the first placement chamber through simple opening and closing operations. This eliminates the need to disassemble the entire device or use complex tools, significantly simplifying daily maintenance and troubleshooting. Furthermore, a first clearance groove 120 is provided on the side of the support facing the second placement chamber, and a second clearance groove 30 is provided at the top of the purification component 3. These two grooves, positioned opposite each other, form a clearance cavity to accommodate the first and second conductive components 4. This design not only protects the first and second conductive components 4 but also allows users to easily access them without interfering with other components, facilitating cleaning or replacement and extending the equipment's lifespan.

[0034] The inspection cover 12 is designed to swing vertically relative to the frame 11, allowing for the inspection and maintenance of the power conversion component 2 and other electrical components within the first placement chamber without requiring disassembly of the inspection cover 12. This facilitates operation and improves the maintainability of the equipment. Furthermore, a certain gap is maintained between the inspection cover 12 and the top of the purification component 3 to prevent interference during assembly or operation, ensuring structural stability and installation reliability.

[0035] Furthermore, the power conversion component 2 and other electrical components inside the first placement cavity are placed on the support.

[0036] Furthermore, when no inspection or maintenance is required, the sealing portion of the inspection cover 12 is fixedly connected to the top of the frame 11 by screws, thereby reliably sealing the first placement cavity, preventing dust from entering and ensuring the stability of the overall structure. When inspection or maintenance of internal components is required, the inspection cover 12 can be opened by simply removing the screws, making the operation simple and quick, further improving the maintainability and ease of use of the equipment.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the frame 11 is provided with at least two sets of connection holes 110, and each set of connection holes 110 is spaced apart on the frame 11. Each set of connection holes 110 is used for connection of the connecting plate. The new air conditioning return air purification device is installed in a preset position through the connecting plate.

[0038] This structural design, using multiple sets of spaced-apart connecting holes 110, allows for the selection of different hole heights and / or connecting plates of varying lengths for fixation during installation, based on actual needs. This adjustable height and length design significantly improves the installation adaptability of the new air conditioning return air purification device, effectively enhancing its versatility and ease of assembly. Furthermore, this structural design eliminates the need for custom-made frames of different specifications for different installation heights, meeting installation requirements in various application scenarios. This significantly reduces production costs and inventory pressure, and facilitates standardized operations for later maintenance and replacement, simplifying the maintenance process. In addition, the multiple sets of connecting holes 110 enhance the overall installation stability of the new air conditioning return air purification device. By rationally selecting the location of the connection points, the weight of the equipment can be effectively distributed, improving the stress balance on the mounting surface and preventing the risk of loosening or detachment due to localized stress concentration. This design ensures the stability of the equipment under various installation conditions, further guaranteeing the safety and reliability of equipment operation.

[0039] Preferably, each set of connection holes 110 consists of two holes.

[0040] Furthermore, such as Figure 2 and Figure 3 As shown, the frame 11 includes: a first frame 111, a second frame 112, a third frame 113, and a fourth frame 114 connected in sequence. The first frame 111 and the third frame 113 are arranged opposite to each other, and the second frame 112 and the fourth frame 114 are arranged opposite to each other. The first frame 111 is located at the top of the second frame 112 and the fourth frame 114, and the third frame 113 is located at the bottom of the second frame 112 and the fourth frame 114. The first frame 111, the second frame 112, the third frame 113, and the fourth frame 114 enclose a placement space 10; a fixing plate 115. The fixing plate 115 is connected to the first frame 111, the second frame 112 and the fourth frame 114 respectively; the fixing plate 115 is located on one side of the first frame 111; the sealing part of the inspection cover 12 is located on the side of the first frame 111 away from the fixing plate 115, and the supporting part of the inspection cover 12 abuts against the fixing plate 115 on the side away from the sealing part; the fixing plate 115, the first frame 111, the second frame 112, the fourth frame 114 and the inspection cover 12 form a first placement cavity; wherein, the inspection cover 12 is hinged to the second frame 112 and the fourth frame 114 respectively.

[0041] This structural arrangement, with the frame 11 cooperating with the fixing plate 115 and the inspection cover 12, divides the placement space into different functional areas (such as the first placement chamber and the second placement chamber), achieving physical isolation between the power conversion components and the purification components, which helps improve the safety and functionality of the equipment operation. Furthermore, the hinged design allows the inspection cover 12 to open at a certain angle, providing a convenient operating space for users to maintain and inspect the power conversion components and other electrical components in the first placement chamber. This not only improves maintenance efficiency but also facilitates troubleshooting and repair work.

[0042] Furthermore, the second frame 112 includes: a first retaining rod, a second retaining rod, and a first movable plate. The first and second retaining rods are spaced apart along the length of the frame 11. The first movable plate is located between the first and second retaining rods and is detachably connected to the first and second retaining rods, as well as the first frame 111 and the third frame 113. And / or the fourth frame 114 includes: a third retaining rod, a fourth retaining rod, and a second movable plate. The third and fourth retaining rods are spaced apart along the length of the frame 11. The second movable plate is located between the third and fourth retaining rods and is detachably connected to the third and fourth retaining rods, as well as the first frame 111 and the fourth frame 114. Therefore, the user can choose to install or remove the purification component 3 from the front or side of the frame 11 based on the available space and actual conditions.

[0043] Furthermore, such as Figure 2 As shown, the inspection cover 12 includes: a first support plate 121, a second support plate 122, and a third support plate 123. The first support plate 121 and the third support plate 123 both extend along the width direction of the frame 11, and the second support plate 122 extends along the height direction of the frame 11. The top ends of the first support plate 121 and the second support plate 122 are connected, and the bottom end of the third support plate 123 is connected to the third support plate 123. The side of the first support plate 121 away from the second support plate 122 is connected to the third support plate 123. The side of the first support plate 123 away from the second support plate 122 is arranged in the opposite direction; the first support plate 121 and the second support plate 122 form a first clearance groove 120; the first support plate 121, the second support plate 122 and the third support plate 123 form a support part; the sealing plate 124 is connected to the first support plate 121, the second support plate 122 and the third support plate 123 respectively, and the sealing plate 124 protrudes from the first support plate 121; the sealing plate 124 forms a sealing part. The bottom of the sealing plate 124 has a notch, which communicates with the first clearance groove 120.

[0044] With this structural design, the support portion of the inspection cover 12 adopts a three-dimensional structure composed of three support plates. This not only enhances the overall strength but also provides dedicated space for conductive components (such as the first and second conductive components) through the first clearance groove 120, avoiding interference with other components and improving the utilization efficiency of internal space. Furthermore, the first support plate 121, the second support plate 122, and the third support plate 123 work together to ensure that the support portion can effectively position and support the purification component 3, ensuring its stability and installation accuracy during operation, while also facilitating disassembly and assembly.

[0045] Among them, the width direction of frame 11 is as follows Figure 1 The direction indicated by the middle arrow A.

[0046] Specifically, such as Figure 2 and Figure 4 As shown, the novel air conditioning return air purification device also includes at least two limiting plates 5. The at least two limiting plates 5 are rotatably mounted on the second frame 112 and the fourth frame 114, respectively. When the purification component 3 is inserted into the second placement cavity from the front of the housing 1, the limiting plates 5 are rotated to form an angle with the second frame 112 and the fourth frame 114, thereby limiting the purification component 3 from the air inlet side of the purification component 3, preventing the purification component 3 from tilting, and enhancing the stability of the purification component 3 in the device.

[0047] Furthermore, such as Figure 4 As shown, both the second frame 112 and the fourth frame 114 have a corresponding storage slot 116 for each limiting piece 5. The limiting piece 5 can be rotated to move into or out of the storage slot 116. When the limiting piece 5 is not in the limiting state, it can be rotated and stored in the storage slot 116. This not only makes the device look neater but also avoids potential interference from the limiting pieces 5 outside the device. Moving the limiting pieces by rotation allows for simple operation—just rotate the limiting piece into or out of the storage slot—to complete the limiting or releasing operation, greatly simplifying the usage process.

[0048] Specifically, such as Figure 2As shown, the purification component 3 includes a micro-electrostatic module 31 and an electric field module 32. The micro-electrostatic module 31 has a power supply compartment and a dust collection plate 311. The power supply compartment is electrically connected to the dust collection plate 311 and is used to provide the required electrical energy to the dust collection plate 311. The dust collection plate 311 is used to adsorb charged particles. The power supply compartment forms the power supply part of the purification component 3. The electric field module 32 is disposed on the dust collection plate 311 and is located on the air inlet side of the micro-electrostatic module 31. The electric field module 32 has an ionization part and is electrically connected to the power supply compartment. The ionization part is used to discharge and charge the particles in the air. The arrangement direction of the ionization part forms a first preset angle with the plane of the housing 1. The first preset angle is greater than or equal to 0° and less than or equal to 90°. With this structural arrangement, the field electrostatic module 32 is positioned on the air inlet side of the micro-electrostatic module 31, ensuring that airborne particles are fully ionized and charged before entering the dust collection area. This significantly improves the adsorption efficiency of the dust collection plate 311, achieving more efficient air purification. Furthermore, the arrangement direction of the ionization unit forms a first preset angle with the plane of the housing 1, which is greater than or equal to 0° and less than or equal to 90°. By tilting the ionization unit, not only is the effective coverage area of ​​the ionization region expanded, but the airflow distribution is also improved, avoiding dead zones caused by unreasonable structural design. This reduces the escape of uncharged particles and improves overall purification efficiency. In addition, it enhances adaptability to airflow from different directions, contributing to the uniform distribution of airflow within the purification channel and reducing local eddies or dead zones.

[0049] Among them, such as Figure 1 As shown, arrow D indicates the air intake direction.

[0050] Furthermore, such as Figure 2 As shown, the field electrostatic module 32 includes: a conductive rod 321 extending vertically and disposed at the air inlet side of the micro electrostatic module 31; the conductive rod 321 is electrically connected to the power supply compartment; there is at least one conductive rod 321; an electrode head 322 connected to the conductive rod 321 and electrically connected to the power supply compartment via the conductive rod 321; the electrode head 322 extends in a predetermined direction and forms an ionization section; wherein there is at least one electrode head 322. 22 is disposed on the conductive rod 321, and the discharge end of the electrode head 322 is located on the side of the conductive rod 321 away from the air inlet side of the dust collection plate 311. The extension direction of the electrode head 322 is perpendicular to the width direction of the housing 1. Alternatively, there is at least one pair of electrode heads 322, and the pair of electrode heads 322 are respectively located on both sides of the conductive rod 321 along the width direction of the housing 1. The extension direction of each electrode head 322 forms a second preset angle with the width direction of the housing 1. The second preset angle is greater than or equal to 0 degrees and less than or equal to 75 degrees.

[0051] With this structural arrangement, the electrode heads 322, positioned perpendicular to the width of the housing 1, ensure a uniform distribution of the ionization region within the air inlet channel. This allows airborne particles to be fully ionized and charged before entering the dust collection plate 311, significantly improving electrostatic adsorption efficiency. When multiple pairs of electrode heads 322 are used, their arrangement not only expands the effective coverage of the ionization region but also optimizes the airflow path, avoiding ionization blind spots and further enhancing the charge-carrying rate of particles.

[0052] Preferably, the field electric module 32 includes two electrode discharge methods: a vertical discharge method, in which the electrode head 322 is arranged perpendicularly to the plane of the housing 1; and a non-vertical discharge method, in which the electrode head 322 is arranged at an angle to the plane of the housing 1. The field electric module 32 employs two electrode discharge methods, allowing the user to flexibly select one of the discharge methods based on air quality and particulate matter size.

[0053] Preferably, when the field electric module 32 adopts a non-perpendicular discharge method, the arrangement direction of the electrode heads 322 can be set at an angle to the plane of the housing 1. Preferably, this angle is greater than or equal to 0 degrees and less than or equal to 75 degrees. When the angle is equal to 0 degrees, the arrangement direction of the electrode heads 322 is parallel to the plane of the housing 1, that is, the field electric module 32 discharges horizontally, and the arrangement direction of each electrode head 322 is parallel to the plane of the housing 1 and also parallel to the plane of the conductive rod 321 (e.g., Figure 5 (As shown); the plane where the electrode head 322 is located and the housing 1 can also be at any angle greater than 0 degrees and less than or equal to 75 degrees. This arrangement is beneficial for the effective charging of airborne particles, thus improving air purification efficiency. The electrode heads 322 are distributed at intervals on the conductive rod 321. They can appear in pairs on both sides of the conductive rod 321, or they can be arranged alternately and at equal intervals on both sides of the conductive rod 321.

[0054] When the field power module 32 discharges vertically, the electrode head 322 is arranged perpendicular to the plane of the conductive rod 321. The electrode head 322 discharges uniformly into the hole opened in the conductive rod 321, resulting in more uniform charging of the particles.

[0055] Furthermore, the electrode head 322 can be any structural form, such as a carbon fiber brush, a bundle of metal wires, or a metal tip. When horizontal discharge is used, the electrode head 322 can be perpendicular to the conductive rod 321, or the two can be at an angle. The shape of the hole on the conductive rod 321 for mounting the electrode head 322 can be circular, elliptical, square, or have rounded corners.

[0056] Furthermore, the purification component 3 also includes: a grounding metal plate, which is disposed on the air inlet side of the micro-electrostatic module 31, and the electrode head 322 is located between the grounding metal plate and the micro-electrostatic module 31; the grounding metal plate has through holes, and there is at least one through hole, which is configured to correspond one-to-one with a pair of electrode heads or a single electrode head.

[0057] Preferably, there are multiple conductive rods 321, which are evenly spaced along the width of the frame 11. When the arrangement direction of the electrode heads 322 is perpendicular to the plane of the conductive rods 321, multiple electrode heads 322 are arranged on each conductive rod 321, thus forming a rectangular array. At the same time, multiple through holes are provided on the grounding metal plate, which are also arranged in a rectangular array, and each through hole corresponds to each electrode head 322.

[0058] Preferably, there are multiple conductive rods 321, which are evenly spaced along the width of the frame 11. When the arrangement direction of the electrode heads 322 forms an angle with the plane of the housing 1 (i.e., the field electric module 32 adopts a non-perpendicular discharge method), multiple pairs of electrode heads 322 are arranged on each conductive rod 321. The multiple pairs of electrode heads 322 are spaced apart along the height of the conductive rod 321. Multiple through holes are opened on the grounding metal plate, and each through hole corresponds to each electrode head 322.

[0059] like Figure 1 As shown, the first embodiment of the structure of the micro electrostatic module 31 provided by this utility model is as follows: the micro electrostatic module 31 includes: an insulating frame 312, a power supply compartment is provided inside the insulating frame 312, an installation space is provided in the insulating frame 312, and the power supply compartment and the installation space are spaced apart along the height direction of the insulating frame 312; the power supply compartment is located above the installation space; a set of dust collection plates 311 are installed in the installation space.

[0060] Furthermore, the top of the insulating frame 312 is provided with a second clearance groove 30, and the second clearance groove 30 is also provided with a running indicator light 6, which is connected to the power supply compartment.

[0061] like Figure 6As shown, a second embodiment of the structure of the micro-electrostatic module 31 provided by this utility model is as follows: The micro-electrostatic module 31 includes: an insulating frame 312, a power supply compartment provided inside the insulating frame 312, an installation space provided in the insulating frame 312, the power supply compartment and the installation space being spaced apart along the height direction of the insulating frame 312; the power supply compartment being located above the installation space; at least one partition 313 extending along the width direction of the insulating frame 312, the partition 313 being disposed within the installation space to divide the installation space into at least two installation cavities; the partition 313 having two opening slots, the two opening slots being spaced apart along the height direction of the insulating frame 312 on the partition 313; both opening slots extending along the extension direction of the partition 313; wherein, there are at least two sets of dust collection plates 311, each set of dust collection plates 311 being disposed one-to-one with each installation cavity, each set of dust collection plates 311 being installed in the corresponding installation cavity, and the top and / or bottom ends of each set of dust collection plates 311 being located in the corresponding opening slots. With this structural design, when the length of the micro-electrostatic module 31 is large, a single, long dust collection plate 311 would easily bend and deform due to its own weight or airflow impact, thus affecting the uniformity and stability of the electrostatic field. By setting multiple separators 313 to divide the installation space into multiple installation cavities, and using multi-segment dust collection plates 311 installed in each cavity, the span of each dust collection plate is effectively shortened, significantly reducing the risk of deformation and improving the overall structural stability and service life. At the same time, the structural design of multi-segment dust collection plates 311 in conjunction with separators 313 creates relatively independent electrostatic adsorption areas between each segment, which helps optimize the electric field distribution, reduce local electric field distortion, and thus improve air purification efficiency. Moreover, with the dust collection plate 311 designed as a multi-segment structure, users can disassemble, clean, or replace only a specific segment of the dust collection plate as needed, without having to dismantle the entire plate. This makes operation more flexible and convenient, greatly reducing maintenance difficulty and time costs, and improving the maintainability of the equipment.

[0062] The connecting plate is an L-shaped connecting plate.
