[0028] Example 1

[0029] This application provides an air purifier cleaning structure, such as... Figures 1 to 3As shown, it includes: a spraying device 1 for spraying fluid onto the surface of the electrostatic adsorption plate 100; an absorption device 2, which is disposed opposite to the spraying device 1 on both sides of the electrostatic adsorption plate 100 for collecting fluid; and a synchronization device 3, which connects the spraying device 1 and the absorption device 2 to enable the spraying device 1 and the absorption device 2 to move synchronously.

[0030] The air purifier cleaning structure provided in this application embodiment can be applied to indoor air purification in homes, air purification in public places such as office buildings or shopping malls, air purification in special environments such as hospital operating rooms or wards, air purification in industrial production workshops, and purification in the field of animal breeding and disease prevention, etc.

[0031] The spraying device 1 is installed on one side of the electrostatic adsorption plate 100 and is used to spray a fluid (such as gas, water, or cleaning agent) at a certain pressure to impact and remove dust and impurities on the electrostatic adsorption plate 100. The absorption device 2 is located on the other side of the electrostatic adsorption plate 100 and is arranged opposite to the spraying device 1. When the spraying device 1 is working, the fluid is sprayed onto the surface of the electrostatic adsorption plate 100. The fluid with a certain pressure passes through the adsorption holes on the surface of the electrostatic adsorption plate 100 and carries away the dust and impurities on the adsorption holes. The absorption device 2 is responsible for collecting the dirt and fluid that have passed through the adsorption holes to prevent them from re-polluting the internal environment of the air purifier. The synchronization device 3 connects the spraying device 1 and the absorption device 2 to ensure that the two can move synchronously, for example, moving horizontally or vertically along the surface of the electrostatic adsorption plate 100. This synchronous movement makes the spraying and absorption operations more precise and efficient.

[0032] The air purifier cleaning structure provided in this embodiment achieves automated cleaning of the electrostatic adsorption plate 100 through a synchronous motion mechanism using a spray device 1 and an absorption device 2 arranged opposite to each other, reducing the need for manual intervention. Since spraying and absorption are performed simultaneously, dust and impurities are prevented from re-adhering to the electrostatic adsorption plate 100 before being absorbed, thus ensuring better cleaning results.

[0033] In some embodiments, the spraying device 1 includes a plurality of nozzles 101 arranged along a first direction, through which fluid can be sprayed onto the surface of the electrostatic adsorption plate 100; the absorption device 2 includes a collection tank 201, the opening of which is arranged opposite to the plurality of nozzles 101, and the size of the opening is able to cover the range of the plurality of nozzles 101.

[0034] The spraying device 1 includes a set of nozzles 101 arranged along a first direction (e.g., horizontal or vertical). The nozzles 101 can be flat, cylindrical, fan-shaped, etc. These nozzles 101 can be evenly distributed at a certain spacing to ensure that the adsorption holes in each area of ​​the electrostatic adsorption plate 100 surface are uniformly cleaned. Each nozzle 101 can generate appropriate spray pressure and angle to ensure that the fluid effectively impacts and removes dust and impurities from the electrostatic adsorption plate 100. The position of the collection tank 201 corresponds to the nozzles 101; that is, the spray direction of the nozzles 101 should be directly opposite the opening of the collection tank 201. The collection tank 201 can be a structure with a rectangular opening on one side of the housing and an internal cavity. The size of the opening of the collection tank 201 must cover the area where all nozzles 101 are located to ensure that all sprayed fluid and its carried impurities are collected.

[0035] By arranging multiple nozzles 101 in the first direction, the coverage area of ​​a single spray action of the spraying device 1 can be expanded, thereby significantly improving cleaning efficiency. At the same time, the large-sized collection tank 201 ensures that all sprayed dirt and fluid are effectively captured, preventing secondary pollution.

[0036] In some embodiments, the surface of the electrostatic adsorption plate 100 in the prior art has multiple adsorption holes arranged in an array, which can capture and retain dust and impurities in the air. The air purifier cleaning structure provided in this application embodiment can provide a row of nozzles 101 on the air outlet side of the electrostatic adsorption plate 100, and a collection groove 201 at the corresponding position on the air inlet side.

[0037] Nozzle 101 has an orifice, which can be of two types: one is a slit-type orifice with a slit width of approximately 0.2 mm; this type of orifice can be an existing structure and is called an air knife. The other type consists of a row of small orifices with a diameter of approximately 1 mm. Both types of orifices can be connected to compressed air, with a pressure between 0.2 MPa and 1.0 MPa, which is suitable for practical applications, with approximately 0.6 MPa being the preferred choice. The compressed air passing through the orifice forms a high-speed jet, thereby increasing the impact kinetic energy to remove dust from the electrostatic adsorption plate 100. The airflow velocity at the orifice can range from approximately 20 m / s to 90 m / s and will not exceed the speed of sound (340 m / s).

[0038] Since the nozzle 101 is movable, the distance between the nozzle and the surface of the electrostatic adsorption plate 100 on the air outlet side must be greater than 5mm to avoid interference. As the gas ejected from the nozzle reaches the surface of the electrostatic adsorption plate 100, it carries surrounding air along with it, causing the airflow to gradually thicken and form a cone shape. Upon reaching the surface of the electrostatic adsorption plate 100, the airflow coverage area can reach 20mm. 2Beyond this range, the airflow speed will also decrease. The diameter of the adsorption holes on the existing electrostatic adsorption plate 100 is generally around 2mm. Therefore, when the jetted airflow reaches the surface of the electrostatic adsorption plate 100, it can cover multiple adsorption holes at the same time. The high-speed airflow will rush out along the adsorption holes of the electrostatic adsorption plate 100, and at the same time wash away the dust attached to the adsorption holes.

[0039] The dust-laden airflow blown from the air inlet side of the electrostatic adsorption plate 100 directly faces the collection tank 201, so the width of the collection tank 201 opening can be around 20mm. The collection tank 201 can be equipped with a separate exhaust fan, creating a negative pressure around it to draw in the scouring airflow ejected from the nozzle. To effectively collect this airflow, the airflow rate of the collection tank 201 can be designed to be greater than the airflow rate ejected from the nozzle.

[0040] The air purifier cleaning structure provided in this embodiment connects the nozzle 101 to compressed air at a certain pressure to form a high-speed jet, achieving targeted cleaning of dust inside the adsorption holes of the electrostatic adsorption plate 100. Utilizing the airflow's movement characteristics, the jet can cover a large area of ​​the adsorption holes of the electrostatic adsorption plate 100, effectively flushing away the dust adhering to them. Simultaneously, by using the collection tank 201 and the equipped exhaust fan to create negative pressure, dust-laden airflow can be efficiently collected, ensuring the effectiveness and thoroughness of the air purifier cleaning process and the cleanliness of the internal environment.

[0041] In some embodiments, the fluid is preferably a high-pressure gas. When the electrostatic adsorption plate 100 needs to be cleaned, the high-pressure gas is ejected at high speed from the nozzle 101, forming a strong airflow. This airflow can penetrate the adsorption holes of the electrostatic adsorption plate 100, blowing dust and impurities away from the plate surface. Using high-pressure gas as the fluid avoids the moisture problems caused to the electrostatic adsorption plate 100 by the use of liquid fluids. In addition, the high-pressure gas jet does not flow along the surface of the electrostatic adsorption plate 100 like a liquid, thus preventing the flow and splashing that liquid fluids may cause.

[0042] In some embodiments, a sealing structure, such as a flexible sealing gasket, sealing brush, or other similar material, is installed around the edge of the collection tank 201. This sealing structure forms a closed barrier during collection, allowing the suction airflow to effectively guide the airflow from the nozzle 101 to be collected in an organized manner within the collection tank 201, preventing fluid and impurities from escaping from the edge of the collection tank 201 and being discharged from the system by the suction fan. Furthermore, when the collection tank 201 is located on the other side of the electrostatic adsorption plate 100, its opening is positioned close to the surface of the electrostatic adsorption plate 100 so that the sealing structure can contact the electrostatic adsorption plate 100. As the collection tank 201 moves, the sealing structure can slide along the surface of the electrostatic adsorption plate 100, and its friction helps to scrape off residual impurities on the electrostatic adsorption plate 100 and draw them into the collection tank 201.

[0043] In some embodiments, the synchronization device 3 includes a drive unit 301, which is connected to the nozzle 101 and the collection tank 201 respectively. The drive unit 301 can drive the nozzle 101 and the collection tank 201 to reciprocate along a second direction; the second direction is perpendicular to the first direction.

[0044] The drive unit 301 can be an electric motor drive system, or a pneumatic or hydraulic drive system. The main function of this drive unit 301 is to provide power and control the synchronous movement of the nozzle 101 and the collection tank 201. The drive unit 301 can be mounted on the support frame 200 of the air purifier. The drive unit 301 can be connected to the nozzle 101 and the collection tank 201 via mechanical transmission components such as chains, belts, gears, or lead screws. The drive unit 301 can drive the nozzle 101 and the collection tank 201 to reciprocate along a second direction (perpendicular to the first direction). This means that the nozzle 101 and the collection tank 201 can move back and forth within a fixed range, thereby achieving comprehensive cleaning of the electrostatic adsorption plate 100. The reciprocating movement can be linear or along a specific trajectory, depending on the shape of the electrostatic adsorption plate 100 and the area to be cleaned. By driving the nozzle 101 and the collection tank 201 to reciprocate along the second direction, the entire surface of the electrostatic adsorption plate 100 can be uniformly cleaned, improving the comprehensiveness and effectiveness of the cleaning.

[0045] In some embodiments, the spraying device 1 further includes at least one first pipe 102 and a fluid supply unit 103, and a plurality of nozzles 101 are connected to the fluid supply unit 103 through the first pipe 102; the first pipe 102 is a flexible hose.

[0046] The fluid supply unit 103, which may be a liquid storage tank or a high-pressure gas source, and has a built-in power drive device such as a pump, is responsible for storing and supplying the fluid required for cleaning, such as gas, water, or cleaning solution. A first conduit 102 connects the fluid supply unit 103 to nozzles 101, through which multiple nozzles 101 are connected to the supply unit. These nozzles 101 can be individually connected to the first conduit 102 or connected via branch conduits.

[0047] To accommodate the movement of the spraying device 1 in the second direction, the first conduit 102 uses a flexible hose. This hose can flexibly follow the movement of the spraying device 1, avoiding the limitations on the range of motion that rigid pipes might impose. At the same time, the hose has good bending resistance and will not be damaged even under frequent bending, thus extending the service life of the equipment.

[0048] In some embodiments, the first conduit 102 may be a spiral bend arranged along a second direction.

[0049] The first conduit 102 is a spiral bend arranged along a second direction (e.g., a vertical direction). This allows the first conduit 102 to extend a relatively long distance within a limited space, and the spiral bend has a certain degree of flexibility to accommodate the reciprocating movement of the jet device 1. The spiral bend reduces the risk of interference and entanglement during movement, and also facilitates its arrangement inside the air purifier.

[0050] In some embodiments, the spraying device 1 further includes a connecting pipe, the connecting pipe being provided with a plurality of first through holes along a first direction, each nozzle 101 being connected to the connecting pipe through the first through hole, and a second through hole being provided in the middle of the connecting pipe, the first pipe 102 being connected to the connecting pipe through the second through hole.

[0051] The connecting pipe is arranged along a first direction (e.g., horizontal) and has multiple first through holes. Each nozzle 101 communicates with the connecting pipe through these through holes. A second through hole is provided in the middle of the connecting pipe for connecting to the first pipe 102 (a spiral bend). This allows fluid to be transported from the fluid supply unit 103 through the first pipe 102 to the connecting pipe and finally to each nozzle 101. Through the multiple first through holes, the fluid can be evenly distributed to each nozzle 101, ensuring the uniformity of pressure and flow during the cleaning process and improving cleaning efficiency.

[0052] In some embodiments, the absorption device 2 further includes at least one second pipe 202 and a negative pressure generating unit, wherein the collection tank 201 is connected to the negative pressure generating unit through the second pipe 202; the second pipe 202 is a flexible hose.

[0053] The negative pressure generating unit is responsible for generating negative pressure to attract fluid and impurities within the collection tank 201. This unit can be a vacuum pump, a fan, or other device capable of generating stable negative pressure. The second pipeline 202 connects the collection tank 201 and the negative pressure generating unit to transfer fluid and impurities within the collection tank 201. To accommodate the movement of the absorption device 2 in the second direction, the second pipeline 202 is a flexible hose.

[0054] The negative pressure generating unit and the second pipeline 202 effectively collect the fluid and impurities sprayed onto the electrostatic adsorption plate 100 by the spraying device 1. While the high-pressure fluid from the spraying device 1 is rinsing, the suction force of the negative pressure acts on the adsorption holes of the electrostatic adsorption plate 100, helping to loosen and remove stubborn dust and impurities. This dual-action mechanism enhances the cleaning power, making it easier to remove dirt from the adsorption holes.

[0055] By using a flexible hose as the second conduit 202, the collection tank 201 becomes more flexible during movement, and its range of motion is not limited by rigid pipes. The hose has good bending resistance and is not prone to breakage or wear even after long-term use, thus extending the service life of the equipment.

[0056] In some embodiments, the second conduit 202 may be a telescopic pipe provided along a second direction.

[0057] The second pipe 202 can be designed as a telescopic pipe arranged along the second direction (vertical direction). The telescopic pipe can be composed of multiple sleeves, each of which can be nested or slid together to achieve the telescopic function. The telescopic pipe allows the collection tank 201 to better adapt to different height changes during movement and ensures that the telescopic pipe can smoothly extend or retract when the spraying device 1 and the absorption device 2 move synchronously, avoiding jamming or obstruction of the collection tank 201 during movement.

[0058] In some embodiments, the second pipes 202 are a pair, and the pair of second pipes 202 are spaced apart along a first direction; the absorption device 2 also includes a manifold 203, and the pair of second pipes 202 are connected to the negative pressure generating unit through the manifold 203, and the negative pressure generating unit can generate negative pressure inside the manifold 203 relative to the outside.

[0059] The second pipes 202 are a pair, spaced apart along the first direction (assuming a horizontal direction). This means that there is one second pipe 202 on each side of the absorption device 2, used to connect different parts of the collection tank 201 to the manifold 203 respectively. This ensures that the fluid and impurities in the collection tank 201 can be evenly distributed and transported to the manifold 203 through the two second pipes 202. The manifold 203 collects the pair of second pipes 202 together and then connects them to the negative pressure generating unit. By collecting the pair of second pipes 202 together through the manifold 203 and connecting them to the negative pressure generating unit, it ensures that even if one pipe has a problem, the other pipe can continue to work, improving the stability and reliability of the system. The manifold 203 should be designed with sufficient space inside to ensure that the fluid can flow in smoothly and be extracted by negative pressure. The manifold 203 can be designed with a certain volume to buffer situations with large instantaneous fluid inflow and avoid overloading the negative pressure generating unit.

[0060] In some embodiments, the inner surface of the collection tank 201 facing the electrostatic adsorption plate 100 is designed as an inclined surface or a curved surface. For the inclined surface, a specific angle can be designed, such as 30 degrees, 45 degrees, or 60 degrees with the horizontal plane, while the curvature of the curved surface can be adjusted according to actual conditions. The inclined or curved surface utilizes gravity to allow fluids and dirt to flow more easily into the manifold 203, thereby improving collection efficiency. Because fluids and dirt can quickly flow into the manifold 203, they avoid staying on the surface of the electrostatic adsorption plate 100 for too long, reducing the possibility of secondary pollution. Furthermore, the inclined or curved surface of the collection tank 201 prevents dirt from accumulating in corners or hard-to-clean areas, facilitating cleaning and maintenance.

[0061] In some embodiments, the spraying device 1 further includes a support rod 104 arranged along a first direction, and a plurality of nozzles 101 are evenly distributed on the support rod 104; the synchronization device 3 further includes a pair of transmission components 302, which are respectively connected to the drive unit 301; the pair of transmission components 302 are arranged opposite to each other along the first direction, and the two ends of the support rod 104 and the two ends of the collection groove 201 are respectively connected to the pair of transmission components 302, and the drive unit 301 drives the support rod 104 and the collection groove 201 to move synchronously through the transmission components 302.

[0062] The support rod 104 is arranged along a first direction (assuming it is horizontal), and multiple nozzles 101 are evenly distributed on the support rod 104 to ensure the stability of the multiple nozzles 101 during movement. Alternatively, the support rod 104 can be a hollow structure, with multiple first through holes on one side surface along the first direction and a second through hole in the middle of the other side surface. The multiple nozzles 101 are connected to the first pipe 102 through the support rod 104. The synchronization device 3 includes a pair of transmission components 302, which can be disposed on the support frame 200 of the air purifier. The pair of transmission components 302 are respectively connected to the drive unit 301. The pair of transmission components 302 are arranged opposite to each other along the first direction. The two ends of the support rod 104 and the two ends of the collection tank 201 are respectively connected to the pair of transmission components 302 to ensure that the support rod 104 and the collection tank 201 can move synchronously under the action of the drive unit 301. The support rod 104 and the collection groove 201 are connected to the transmission assembly 302 at both ends, ensuring stability in reciprocating motion and reducing vibration or deviation caused by imbalance.

[0063] In some embodiments, both the connecting pipe and the support rod 104 are arranged along a first direction (e.g., a horizontal direction). The connecting pipe communicates with a plurality of nozzles 101, and the support rod 104 is rotatably connected to the connecting pipe via a rotating shaft. Both ends of the support rod 104 are respectively connected to a pair of transmission components 302 of the synchronization device 3, and the support rod 104 can reciprocate along a second direction (e.g., a vertical direction) in a direction parallel to the electrostatic adsorption plate 100 via the synchronization device 3.

[0064] A rotating shaft is located in the middle of the support rod 104 and the connecting pipe. It also includes a driving component, such as a drive motor, connected to the rotating shaft to drive its rotation. The connecting pipe can rotate relative to the support rod 104 by a preset angle, such as 5-10 degrees, via the rotating shaft, thereby changing the overall spray angle of the multiple nozzles 101 arranged on the connecting pipe. Since multiple nozzles 101 are arranged on the connecting pipe, there must be a certain distance between each nozzle 101. If the spacing between the adsorption holes on the electrostatic adsorption plate 100 is small, the sprayed fluid may not be able to cover the adsorption holes located between the nozzles 101, resulting in poor cleaning performance.

[0065] The air purifier cleaning structure provided in this embodiment of the application can thoroughly clean the adsorption holes on the surface of the electrostatic adsorption plate 100 by changing the direction of the multiple nozzles 101 spraying fluid toward the electrostatic adsorption plate 100, leaving no dead corners. The rotatable angle of the connecting pipe is set according to the vertical distance from the support rod 104 to the surface of the electrostatic adsorption plate 100, so that after the connecting pipe is rotated, the two ends of the support rod 104 will not scrape the surface of the electrostatic adsorption plate 100 when it drives the connecting pipe to move.

[0066] In some embodiments, the transmission component 302 is any one of a lead screw and nut structure, a linear sliding structure, or a pulley block structure.

[0067] The air purifier includes a support frame 200 structure, an electrostatic adsorption plate 100 fixedly or detachably mounted on the support frame 200, and the two sides of the support frame 200 located on the electrostatic adsorption plate 100 are defined as the first side and the second side. The spray device 1 is located on the first side and the absorption device 2 is located on the second side.

[0068] Specifically, such as Figure 4 and Figure 5 As shown, in the lead screw and nut structure, a pair of lead screws 305 are respectively arranged on the first side of the support frame 200. The pair of lead screws 305 are arranged opposite each other along the first direction (horizontal direction). The two ends of the support rod 104 are respectively connected to the pair of lead screws 305. The lead screws 305 serve as drive shafts and are arranged along the second direction (vertical direction). Each lead screw 305 is provided with a nut 306 rotatably connected to the lead screw 305. The two ends of the support rod 104 are connected to the lead screw 305 through the nuts 306. Similarly, a pair of lead screws 305 are respectively arranged on the second side of the support frame 200. The two ends of the collecting groove 201 are connected to the lead screws 305 through the nuts 306. The drive unit 301 (e.g., a motor) is located at the top or bottom of the support frame 200. The ends of each lead screw 305 located on both sides of the support frame 200 can be connected to the drive unit 301 via a chain or belt 307. By controlling the rotation of the lead screw 305 through the drive unit 301, the nut 306 can be driven to move axially along the lead screw 305, thereby realizing the reciprocating motion of the support rod 104 and the collection groove 201.

[0069] Specifically, in the linear sliding structure, a pair of slide rail structures are respectively provided on the first side of the support frame 200. The pair of slide rails are arranged opposite each other along the first direction (horizontal direction), and the two ends of the support rod 104 are respectively slidably connected to the pair of slide rails via sliders. Similarly, a pair of slide rails are respectively provided on the second side of the support frame 200, and the two ends of the collection groove 201 are slidably connected to the lead screw 305 slide rail. The drive unit 301 can be a linear motor, which is driven and connected to each slider, which can be connected through a motor shaft and a gear or threaded pair inside the slider. When the linear motor is started, the linear motion it generates is transmitted to the support rod 104 and the collection groove 201 through the slider. Since the sliders of the support rod 104 and the collection groove 201 are all connected to the same linear motor, they can move synchronously in the same direction at the same time.

[0070] Specifically, such as Figure 1 and Figure 2As shown, in the pulley block structure, the pulley block structure may include a set of pulleys 303 and a traction rope 304 or chain. The pulleys 303 are fixed to both sides of the support frame 200 to ensure that the traction rope 304 or chain maintains the correct trajectory during movement. The number and arrangement of the pulleys 303 depend on the required range of motion and accuracy. The traction rope 304 or chain is wound around the pulleys 303 fixed to both sides of the support frame 200, forming a closed loop. One end of the rope or chain is connected to the drive unit 301, and the other end is connected to the support rod 104 or the collection trough 201. The drive unit 301 can be an automatic rotating device, such as a combination of a motor and a reducer, or a manual rotating device, such as a handwheel, with its drive shaft extending through the support frame 200. When the drive unit 301 rotates, it transmits power through the traction rope 304 or chain. The movement of the rope or chain on the pulleys 303 is converted into linear movement of the support rod 104 and the collection trough 201. Since the support rod 104 and the collection tank 201 are respectively connected to the two ends of the traction rope 304 or chain, they can move synchronously in the same direction. Therefore, by driving a handwheel on one side of the electrostatic adsorption plate 100, the synchronous movement of the support rod 104 and the collection tank 201 can be achieved. Alternatively, the drive unit 301 can be located on the top of the support frame 200. By reasonably arranging multiple pulleys 303 on the top of the support frame 200, and by utilizing the principle that pulleys 303 can change the direction of force, the traction rope 304 can be wound around multiple pulleys 303. The drive unit 301 can be controlled from the top of the support frame 200, thereby achieving the synchronous movement of the support rod 104 and the collection tank 201. This can greatly reduce the burden on operators and improve the convenience of work.

[0071] Through the above specific embodiments, the spraying device 1 and the absorption device 2 in this application embodiment can not only efficiently complete the cleaning work of the electrostatic adsorption plate 100, but also ensure stability and reliability in synchronous movement. The application of different types of transmission components 302 allows the system to select the most suitable solution according to specific needs, and also facilitates daily maintenance and upkeep.

[0072] In some embodiments, the air purifier cleaning structure further includes a control system for coordinating the actions of the spray device 1 and the absorption device 2 to ensure that they can operate synchronously and to adjust various parameters according to preset conditions.

[0073] The control system can be built based on a microcontroller or PLC (Programmable Logic Controller), comprising both hardware (such as controllers, sensors, actuators, etc.) and software (control algorithms and programs). The control system activates the spraying device 1 according to a preset program, spraying fluid onto the surface of the electrostatic adsorption plate 100. The control system allows the operator to preset the flow rate, spraying time, and spraying interval of the sprayed fluid, ensuring that the fluid impacts and removes particles from the electrostatic adsorption plate 100 with optimal parameters. The control system ensures that the absorption device 2 is activated synchronously while the fluid is being sprayed to prevent fluid and impurities from accumulating on the electrostatic adsorption plate 100. The control system communicates with the drive unit 301, controlling the synchronous movement of the nozzle 101 and the collection tank 201 in a second direction (such as the vertical direction). By preset the moving speed, moving distance, and stopping position, the uniformity and effectiveness of the cleaning process are ensured. By coordinating the actions of the spraying device 1 and the absorption device 2 through the control system, the entire cleaning process can be automated, reducing the need for manual operation and improving operational safety and convenience.

[0074] The air purifier cleaning structure provided in this application embodiment can not only efficiently complete the cleaning of the electrostatic adsorption plate 100, but also ensure the effective utilization and treatment of fluids during the cleaning process, thereby improving the cleaning efficiency and effect.

[0075] The air purifier cleaning structure provided in this application embodiment can be applied to livestock farm environments. Air purification is crucial in livestock farms, as poor air quality can lead to the spread of animal diseases and affect farming efficiency. Due to the harsh air environment in livestock farms, the electrostatic adsorption plate 100 easily accumulates a large amount of dirt quickly, requiring regular cleaning.

[0076] Traditional cleaning methods have many drawbacks in livestock farms. Disassembling and cleaning dust panels takes an average of 2 to 3 hours each time, and due to the complex environment of livestock farms, disassembly and reassembly are cumbersome and prone to damaging equipment. While direct cleaning with vacuum equipment is faster, multiple cleaning sessions are required to achieve a satisfactory effect, resulting in low overall cleaning efficiency. Frequent disassembly and cleaning can damage the electrostatic adsorption plates and other components, increasing maintenance costs. Furthermore, due to unsatisfactory cleaning results, more frequent component replacements are needed, further increasing costs.

[0077] The air purifier cleaning structure of this embodiment sprays a specially formulated cleaning agent or other fluid onto the surface of the electrostatic adsorption plate 100, which can efficiently dissolve adsorbed pollutants such as dust, bacteria, and viruses. The absorption device 2 is positioned opposite the spraying device 1 on both sides of the electrostatic adsorption plate 100, and can promptly collect the sprayed fluid and the washed-off dirt. The synchronization device 3 connects the two, ensuring synchronized movement and guaranteeing that the surface of the electrostatic adsorption plate 100 is cleaned evenly without any missed areas.

[0078] For example, in large-scale pig farms, air purifiers are installed in the pigsty ventilation system. Without cleaning, the surface of the electrostatic adsorption plate has a bacterial and viral content of 100 CFU / m³. 3 The particulate matter concentration was 150 μg / m³. 3 After the air purifier has been running for a period of time, the cleaning mechanism is activated. The spray device 1 and the absorption device 2 move slowly under the drive of the synchronization device 3, thoroughly cleaning the electrostatic adsorption plate 100. The cleaning process can be completed within half an hour, with significant results. The spray device 1 powerfully sprays fluid, quickly dissolving and flushing away dirt, while the absorption device 2 collects it simultaneously, avoiding secondary pollution and improving cleaning efficiency. Regular use of this cleaning mechanism can maintain the good purification performance of the electrostatic adsorption plate 100. Experimental data shows that after use, the bacterial and viral content drops to 100 CFU / m³. 3 The particulate matter concentration dropped to 15 μg / m³ 3 The removal rate of bacteria and viruses is increased to over 90%, significantly better than traditional cleaning methods, providing a cleaner air environment for farms. Furthermore, the superior cleaning effect extends the service life of the electrostatic adsorption plates, and the synchronization device ensures a stable and reliable cleaning process, reducing the risk of equipment damage and lowering maintenance costs.

[0079] Example 2

[0080] This application provides an air purifier, which includes an electrostatic adsorption plate 100 and a cleaning structure. The cleaning structure includes a spray device 1 disposed on the air outlet side of the electrostatic adsorption plate 100, an absorption device 2 disposed on the air inlet side of the electrostatic adsorption plate 100, and a synchronization device 3 connected to the spray device 1 and the absorption device 2 so that the spray device 1 and the absorption device 2 have synchronous movement performance.

[0081] An electrostatic adsorption plate 100 is located inside the air purifier and has an array of adsorption holes on its surface for adsorbing particulate matter and pollutants in the air. The electrostatic adsorption plate 100 typically possesses an electrostatic field, enabling it to effectively capture dust particles in the passing air. A spray device 1 is positioned on the air outlet side of the electrostatic adsorption plate 100 (i.e., the direction in which air leaves the electrostatic adsorption plate 100). The spray device 1 includes multiple nozzles 101, which are evenly distributed along a first direction (e.g., horizontal) on a support rod 104 and connected to a fluid supply unit 103 via a first conduit 102, spraying high-pressure gas row by row onto the surface of the electrostatic adsorption plate 100. An absorption device 2 is positioned on the air inlet side of the electrostatic adsorption plate 100 (i.e., the direction in which air enters the electrostatic adsorption plate 100). The absorption device 2 includes a collection tank 201 for collecting the fluid sprayed onto the surface of the electrostatic adsorption plate 100 by the spray device 1 and passing through the adsorption holes, as well as impurities washed down by the fluid. The air purifier also includes a support frame 200, an electrostatic adsorption plate 100 disposed on the support frame 200, and a synchronization device 3 disposed on the support frame 200. The synchronization device 3 connects the jet device 1 and the absorption device 2 to ensure that the two can move synchronously in a second direction (e.g., the vertical direction).

[0082] The air purifier provided in this application embodiment not only enables automated cleaning of the electrostatic adsorption plate 100, reducing the need for manual intervention and improving cleaning efficiency, but also, by employing a synchronous motion mechanism, allows spraying and absorption to proceed simultaneously, preventing dust and impurities from re-adhering to the electrostatic adsorption plate 100 before being absorbed, thereby ensuring a better cleaning effect.

[0083] Example 3

[0084] This application provides a method for cleaning an air purifier, the air purifier including an electrostatic adsorption plate 100, the method including: spraying fluid onto the air outlet side surface of the electrostatic adsorption plate 100; absorbing fluid passing through the adsorption holes of the electrostatic adsorption plate 100 on the air inlet side of the electrostatic adsorption plate 100; and separating particles from the absorbed fluid.

[0085] First, a jetting device 1 sprays fluid onto the outlet surface of the electrostatic adsorption plate 100. The fluid, which can be a gas, is used to wash away particulate matter and contaminants adhering to the adsorption pores on the surface of the electrostatic adsorption plate 100. Then, an absorption device 2 is installed on the inlet side of the electrostatic adsorption plate 100 to absorb the fluid passing through the adsorption pores. The absorbed fluid contains particulate matter washed off the surface of the electrostatic adsorption plate 100. In the collection tank 201, a filter screen or other filtration device can be used for preliminary separation of the fluid. The separated particulate matter can be collected and processed, while the cleaned fluid can be recycled or discharged.

[0086] The air purifier cleaning method provided in this application embodiment effectively removes particulate matter and impurities adsorbed on the adsorption holes by spraying high-pressure fluid onto the electrostatic adsorption plate 100, maintaining the cleanliness and efficient adsorption capacity of the electrostatic adsorption plate 100. By drawing fluid from the air inlet side, it prevents dirt generated during the cleaning process from re-entering the air purifier, avoiding secondary pollution. The separation step ensures that particulate matter in the drawn fluid is effectively removed, improving the cleaning effect and extending the service life of the air purifier. The air purifier cleaning method provided in this application embodiment simplifies the air purifier maintenance process, allowing users to more conveniently perform regular cleaning and maintain the performance of the air purifier.

[0087] In some embodiments, the spraying and suction actions are controlled to be performed simultaneously.

[0088] The synchronization mechanism can be achieved through electrical signals or mechanical linkage. The spraying device 1 and the absorption device 2 are simultaneously activated by commands from the control system. The spraying device 1 begins spraying high-pressure fluid onto the outlet surface of the electrostatic adsorption plate 100, while the absorption device 2 initiates its suction action on the inlet side. The nozzle 101 of the spraying device 1 uniformly sprays fluid, which passes through the adsorption holes of the electrostatic adsorption plate 100, flushing out dust and impurities. Simultaneously, the absorption device 2 generates negative pressure on the inlet side, sucking up the fluid and its carried impurities that have passed through the adsorption holes. During the spraying and suction process, the synchronization device 3 ensures that the spraying device 1 and the absorption device 2 move synchronously along the surface of the electrostatic adsorption plate 100. This movement can be horizontal or vertical, ensuring that the entire surface of the electrostatic adsorption plate 100 is uniformly cleaned.

[0089] The simultaneous spraying and suction ensures the continuity and efficiency of the cleaning process, reducing cleaning time. Furthermore, the simultaneous spraying and suction effectively prevents impurities and dirt from being airborne during cleaning, reducing secondary pollution of indoor air.

[0090] In some embodiments, the fluid is divided into multiple beams along a first direction, and the jet direction of the multiple fluid beams is controlled to be at a preset angle to the surface of the electrostatic adsorption plate 100.

[0091] The fluid is split into multiple beams along a first direction (assuming a horizontal direction), which can be achieved by multiple nozzles 101 or an array of nozzles 101 with multiple outlets. The outlet of each nozzle 101 or the array of nozzles 101 is controlled so that the jet direction of the multiple fluid beams forms a preset angle with the surface of the electrostatic adsorption plate 100. This angle can be preset according to the material of the electrostatic adsorption plate 100, the size and distribution of the adsorption holes, and the desired cleaning effect. For example, it can be set between 5° and 10° to ensure that the fluid can effectively impact and remove dust and impurities clogging the adsorption holes. During the jetting process, the jetting device 1 moves along the surface of the electrostatic adsorption plate 100, which can be continuous or stepwise to ensure that the entire plate surface is cleaned uniformly.

[0092] By dividing the fluid into multiple beams and controlling the jet direction of each beam at a preset angle to the surface of the electrostatic adsorption plate 100, it can be ensured that the fluid can evenly cover the surface of the electrostatic adsorption plate 100 and effectively impact and remove dust and impurities clogging the adsorption holes. The selection of the preset angle can optimize the impact effect of the fluid, making the cleaning more thorough. Especially for dirt that is difficult to remove, an appropriate angle can increase the impact force and improve the cleaning effect.

[0093] In some embodiments, step one controls the multiple fluid jets to move gradually from a first position to a second position along a second direction at a first angle; step two controls the multiple fluid jets to move gradually in the opposite direction from the second position to the first position along a second direction at a second angle; step three controls the multiple fluid jets to move gradually in the opposite direction from the first position to the second position again along a second direction at a third angle; wherein the second angle and the third angle are the same angle with different directions.

[0094] Specifically, multiple nozzles 101 are evenly distributed on the connecting pipe, which is connected to the support rod 104 via a rotating shaft. Initially, the support rod 104 is positioned along a first direction (e.g., horizontal), and the connecting pipe is parallel to the support rod 104, with an angle of 0 degrees between them. Assuming the electrostatic adsorption plate 100 is perpendicular to the ground, the first position is the top of the electrostatic adsorption plate 100, and the second position is the bottom of the electrostatic adsorption plate 100.

[0095] In step one, multiple streams of fluid are controlled to move gradually from a first position (top of electrostatic adsorption plate 100) to a second position (bottom of electrostatic adsorption plate 100) at a first angle along a second direction (e.g., vertical). At this time, the connecting pipes remain parallel to the support rod 104, and the jet direction of the multiple streams of fluid is perpendicular to the surface of the electrostatic adsorption plate 100, which can perform a preliminary and comprehensive rinsing of the electrostatic adsorption plate 100, removing most of the more obvious dirt.

[0096] In step two, the fluid jet direction is controlled to move gradually from the second position (bottom of the electrostatic adsorption plate 100) to the first position (top of the electrostatic adsorption plate 100) along the second direction at a second angle. Here, the angle between the connecting pipe and the support rod 104 is 5 degrees, so that the jet direction of the multiple fluid jets forms an angle with the surface of the electrostatic adsorption plate 100. This angle setting allows the fluid to impact adsorption holes that may not have been covered in step one, as well as some corners and edge areas, further improving the cleaning effect.

[0097] In step three, the fluid jet direction is controlled to move gradually from the first position (top of electrostatic adsorption plate 100) to the second position (bottom of electrostatic adsorption plate 100) along the second direction at a third angle. The third angle can be -5 degrees, which is opposite in direction to the second angle but the same angle. This can be achieved by rotating the shaft 10 degrees in the opposite direction in step two, so that the jet direction of the multiple fluid jets forms an angle with the surface of the electrostatic adsorption plate 100. This allows the electrostatic adsorption plate 100 to be cleaned again, ensuring that areas that may have been missed in step two are also thoroughly cleaned.

[0098] The entire cleaning process can be automated by a control system that communicates with the drive unit that drives the rotating shaft. This system allows for remote control of the shaft's rotation direction and angle, reducing manual intervention and labor intensity. Through three steps of spraying at different angles, it ensures that all areas of the electrostatic adsorption plate 100 are covered by fluid, including easily overlooked areas such as adsorption holes, corners, and edges, thereby improving cleaning accuracy, reliability, and efficiency.

[0099] In some embodiments, the spraying and suction actions are controlled to move gradually along the second direction at preset time intervals; the first and second directions are set perpendicularly.

[0100] The timing and frequency of the spraying and suction actions can be coordinated by a control system to ensure that both move gradually in a second direction (e.g., vertical) with preset time intervals between them. The control system can be an automated control system based on a microcontroller or PLC (Programmable Logic Controller) for precise control of the actions of the spraying device 1 and the suction device 2. A preset time interval is set between the spraying and suction actions to ensure that the sprayed fluid has sufficient time to contact the dust and impurities on the surface of the electrostatic adsorption plate 100 and can be effectively absorbed. The preset time interval can be adjusted according to the properties of the fluid and the degree of contamination of the electrostatic adsorption plate 100 to achieve the best cleaning effect.

[0101] Specifically, the control system uses a motor drive or pneumatic device to achieve the gradual movement of the spraying device 1 and the absorption device 2 in the second direction. For example, using a stepper motor, the movement accuracy at the millimeter level can be achieved by precisely controlling the number of steps and the speed of the motor. For example, setting the movement to 10 centimeters per minute, this distance is set according to the distance between adjacent rows of adsorption holes. This ensures that during the cleaning process, the entire surface of the electrostatic adsorption plate 100 is covered while the adsorption holes are precisely cleaned. The control system uses a timer or clock module to precisely control the timing and frequency of the spraying and suction actions. For example, the spraying device 1 is set to spray fluid once every 5 seconds, with each spray lasting 1 second. This time interval ensures that the sprayed fluid has sufficient time to fully contact the dust and impurities on the surface of the electrostatic adsorption plate 100. The absorption device 2 begins suction 2 seconds after the spraying action ends and lasts for 3 seconds. This timing arrangement ensures that the dirt washed down by the fluid is collected by the absorption device 2 in a timely manner, avoiding secondary pollution, and also ensuring the continuity and efficiency of the entire cleaning process.

[0102] In some embodiments, a detection device, such as an optical sensor, can be used to determine the cleanliness by detecting the intensity of light reflected or transmitted from the surface of the electrostatic adsorption plate 100. For the detection of bacteria and viruses, fluorescent markers (such as those using fluorescently labeled test reagents) can be excited by light of a specific wavelength, and the quantity of bacteria and viruses can be indirectly determined by detecting the fluorescence intensity. For the detection of particulate matter concentration, the principle of light scattering can be used; when a light beam shines on particulate matter in the air, scattering occurs, and the concentration of particulate matter can be estimated by detecting the intensity of the scattered light. Alternatively, an image recognition device can be used. This device uses a high-definition camera to capture images of the surface of the electrostatic adsorption plate 100, and analyzes features such as dirt, color, and texture in the image using image processing algorithms to determine the cleanliness. For the detection of bacteria and viruses, specific dyes or markers can be used to make bacteria and viruses appear distinct in the image, facilitating identification and counting. The detection device can be located on the side of the spraying device 1 facing the electrostatic adsorption plate 100, for example, integrated inside the support rod 104. The testing equipment can accurately measure indicators such as the cleanliness of the surface of the electrostatic adsorption plate 100 after cleaning, the removal rate of bacteria and viruses, and the degree of reduction in particulate matter concentration.

[0103] For example, a good cleaning effect can be defined as a cleanliness level of 95% or higher, a bacteria and virus removal rate of 90% or higher, and a particulate matter concentration reduction of 80% or higher. Only when these indicators meet or exceed the set standards is the cleaning effect considered good. To ensure the continuous stability of the cleaning effect, it can be evaluated periodically. For example, a comprehensive test can be conducted after every 10 cleaning cycles. Cleaning parameters can be adjusted based on the test results, and intelligent control algorithms can be used for automatic adjustment. If the cleanliness level does not meet the requirements, the jet pressure or fluid flow rate can be increased to enhance the flushing ability against dirt; if the bacteria and virus removal rate is low, a fluid with bactericidal and disinfecting functions can be considered to improve the disinfection effect; if the reduction in particulate matter concentration is not significant, the power of the suction device can be increased to ensure that particulate matter can be effectively collected.

[0104] In some embodiments, the fluid is steam, and the flow rate is not less than 20 to 300 m / s; or, the fluid is air, and the flow rate is not less than 10 to 300 m / s; or, the fluid is a liquid, and the flow rate is not less than 0.5 to 50 m / s.

[0105] When the fluid is steam, a steam generator can be connected to the injection device 1. The steam generator can be a boiler or other equipment capable of generating high-temperature, high-pressure steam. The injection device 1 consists of nozzles 101, which are designed to generate high-speed steam jets to ensure a steam velocity of not less than 20 to 300 m / s. The number and layout of the nozzles 101 can be adjusted according to the size and contamination level of the electrostatic adsorption plate 100. The absorption device 2 is located on the other side of the electrostatic adsorption plate 100 and can be a gas collection hood or other equipment capable of collecting steam and dirt. The absorption device 2 is connected to the treatment system via pipeline to treat or discharge the collected steam and dirt. The synchronization device 3 can be a mechanical transmission mechanism or an electronic control system to ensure that the injection device 1 and the absorption device 2 can move synchronously to ensure thorough cleaning of the electrostatic adsorption plate 100. Steam has a high-temperature sterilization effect, which can disinfect the electrostatic adsorption plate 100 while cleaning, reducing the growth of bacteria and viruses.

[0106] When the fluid is air, the air can be supplied by a compressed air source, such as an air compressor. Compressed air is delivered to the spraying device 1 via pipeline. The spraying device 1 can be a spray gun or a group of nozzles 101. By adjusting the orifice diameter and pressure of the nozzles 101, the airflow velocity is maintained at a level not less than 10 to 300 m / s. Different types of nozzles 101 and spray angles can be selected based on the size and shape of the electrostatic adsorption plate 100. The absorption device 2 can be a vacuum cleaner or a filter used to collect the dirt blown down by the air. The absorption device 2 is positioned opposite the spraying device 1 to ensure effective dirt collection. The synchronization device 3 can achieve synchronized movement of the spraying device 1 and the absorption device 2 via motor drive or other means to ensure uniform cleaning.

[0107] When the fluid is a liquid, it can be a detergent, water, or other suitable cleaning solution. The liquid is delivered to the spraying device 1 via a pump or pressure tank. The spraying device 1 can be a nozzle or a sprayer, and the liquid flow rate is maintained at a minimum of 0.5 to 50 m / s by adjusting the nozzle orifice diameter and pressure. Different liquids and spraying methods can be selected depending on the degree of contamination and material of the electrostatic adsorption plate 100. The absorption device 2 can be a water tank or a water suction device used to collect the sprayed liquid and dirt. The absorption device 2 should cooperate with the spraying device 1 to ensure that the liquid can be collected and treated smoothly. The synchronization device 3 can achieve synchronized movement of the spraying device 1 and the absorption device 2 through mechanical transmission or electronic control to improve cleaning efficiency and effectiveness.

[0108] Different types of dirt on the electrostatic adsorption plate 100 can be effectively cleaned by using steam, air, or liquid at different flow rates. The impact force of the high-speed fluid can quickly remove stubborn dirt and improve cleaning efficiency.

[0109] In some embodiments, the temperature of the fluid is controlled to be between -40 and 60°C.

[0110] A temperature sensor can be installed to monitor the fluid temperature in real time. The temperature sensor can be placed at the outlet of the injection device 1 or near the electrostatic adsorption plate 100 to accurately measure the fluid temperature when it acts on the electrostatic adsorption plate 100. A temperature control device can be connected, which can adjust the fluid temperature according to a set temperature range. For example, for steam, the output temperature of the steam generator can be adjusted; for liquid, the temperature can be adjusted using heating or cooling devices; and for air, the temperature can be controlled using heat exchangers or heaters.

[0111] During the cleaning process, an appropriate fluid temperature is selected based on the contamination level and material characteristics of the electrostatic adsorption plate 100. For example, for stubborn oil or protein stains, a higher temperature may help dissolve and remove the stains better; while for temperature-sensitive materials, a lower temperature can prevent damage to the electrostatic adsorption plate 100. While the synchronization device 3 drives the spraying device 1 and the absorption device 2, the temperature control device continuously monitors and adjusts the fluid temperature to ensure that the fluid temperature remains within the range of -40 to 60°C throughout the cleaning process. This temperature range of -40 to 60°C covers a wide range of applications, adapting to different environmental conditions and cleaning needs. Different temperature ranges can accommodate different types of stains and contaminants. By controlling the fluid temperature between -40 and 60°C, the fluid temperature can be adjusted according to actual conditions, whether in cold winters or hot summers, ensuring cleaning effectiveness and normal equipment operation.

[0112] In some embodiments, the medium of the fluid is any one of air, steam, water, aqueous solution, or solid particles.

[0113] The purging action of air can remove surface dust and loose dirt; the high temperature and dissolving power of steam can soften and remove stubborn stains; water and aqueous solutions can dissolve water-soluble dirt and rinse it off; the impact force of solid particles can remove dirt that is difficult to remove.

[0114] This application provides a variety of fluid media options, which can be flexibly applied according to different cleaning needs and scenarios. For example, for lightly contaminated electrostatic adsorption plates 100, air or water can be selected for cleaning; for stubborn stains or cases requiring sterilization and disinfection, steam or an aqueous solution containing disinfectant can be selected; for electrostatic adsorption plates 100 made of special materials, solid particles can be selected for cleaning to avoid damage to the material.

[0115] The air purifier cleaning method provided in this application embodiment can not only efficiently complete the cleaning of the electrostatic adsorption plate 100, but also ensure the effective utilization and treatment of fluids during the cleaning process, thereby improving the cleaning efficiency and effect.

[0116] Example 4

[0117] This application provides an air purification method, which includes a purification step and a cleaning step. The purification step involves using an electrostatic adsorption plate 100 to adsorb and separate particles in the air to form purified air. The cleaning step involves spraying fluid onto the electrostatic adsorption plate 100 that has adsorbed particles, causing the particles to detach from the electrostatic adsorption plate 100, and simultaneously drawing in the fluid that has passed through the adsorption holes of the electrostatic adsorption plate 100.

[0118] Air is drawn in through the air inlet of the air purifier and enters the chamber containing the electrostatic adsorption plate 100. The electrostatic adsorption plate 100 carries an electrostatic field; when air containing particulate matter passes through it, the particles are captured, thus separating the particles from the air. The electrostatic adsorption plate 100 typically carries a high-voltage electric field, using electrical charge to attract particulate matter to the plate, ensuring that most of the particulate matter in the air is effectively removed. The air after electrostatic adsorption, i.e., purified air, is discharged through the air purifier's outlet, providing clean air.

[0119] When the electrostatic adsorption plate 100 needs cleaning, the spraying device 1 is activated to spray a preset fluid (such as water or cleaning solution) onto the surface of the electrostatic adsorption plate 100. An absorption device 2 is installed on the air inlet side of the electrostatic adsorption plate 100 to absorb the fluid flowing down the surface of the electrostatic adsorption plate 100 after the sprayed fluid. The spraying device 1 and the absorption device 2 are connected by a synchronization device 3 to ensure that they can move gradually along a second direction (assuming it is vertical), with preset time intervals during the movement.

[0120] By using the electrostatic adsorption plate 100 to adsorb and separate particulate matter in the air, pollutants such as dust, pollen, and smoke can be effectively removed, improving air quality. By spraying fluid onto the electrostatic adsorption plate 100 and simultaneously absorbing the fluid, particulate matter on the plate can be effectively removed, ensuring its cleanliness and restoring its adsorption performance. Through a control system that coordinates the actions of the spraying device 1 and the absorption device 2, the entire cleaning process can be automated, reducing the need for manual operation and improving safety and convenience.

[0121] The air purification method provided in this application not only efficiently completes air purification but also ensures that the electrostatic adsorption plate 100 can be effectively cleaned after a period of use, thereby improving the purification efficiency and service life of the air purifier. The application of synchronous control makes the entire system more efficient and reliable, while also facilitating daily maintenance and upkeep.

[0122] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
