[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments: Please see Figures 1-14 The present invention provides a technical solution: A cleanroom air conditioning system includes an air-facing component 1 connected to the air outlet of a central air conditioning unit and a connecting component 4 that penetrates and is fixed to the cleanroom wall 5. The windward assembly 1 includes a windward duct 102 and a windward drive component rotatably disposed inside the windward duct 102; The outer end of the air-inlet duct 102 is provided with a first flange 101 that connects to the air outlet of the central air conditioning system. The first flange 101 provided on the outer end of the air-inlet duct 102 is used to directly connect to the air outlet of the central air conditioning system. The flange connection method has the characteristics of strong connection and excellent sealing performance, which can ensure that the central air conditioning air enters the air-inlet duct 102 stably and without leakage, avoid the reduction of air supply efficiency due to air leakage, and facilitate the installation and disassembly of the air-inlet component 1 and the central air conditioning system. The first flange 101 has an embedded sealing ring 108, which further fills the gap at the flange joint and enhances the sealing effect. This not only reduces airflow leakage but also reduces the noise generated by airflow impacting the flange gap, thus improving the stability of system operation.

[0020] The windward drive component includes a first bearing cylinder 106 with several sets of first support arms 103 centrally fixed inside the windward duct 102, a first rotating shaft 105 that drives through the first bearing cylinder 106, a windward fan blade 104 fixed to the outer end of the first rotating shaft 105, and a first mating gear 107 fixed to the inner end of the first rotating shaft 105.

[0021] The fan blade 104 is fixed to the outer end of the first rotating shaft 105 and can directly receive the impact force of the central air conditioning airflow. It can rotate without additional drive equipment, which greatly saves system energy consumption. The first docking toothed disc 107 is fixed to the inner end of the first rotating shaft 105 and is used to mesh with the third docking toothed disc 303 of the docking component. The toothed disc meshing method has the advantages of precise transmission and low power loss, which can ensure that the power of the windward drive component is stably transmitted to the clean rotating component and the air guide drive component, and ensure that all components operate synchronously.

[0022] The connecting component 4 includes a connecting pipe 402 and an air guide drive component that is rotatably disposed inside the connecting pipe 402; A second flange 401 is provided on the connecting pipe 402 and fixed to the outer wall of the clean room wall 5.

[0023] The air guide drive component includes a second bearing cylinder 406 with several sets of second support arms 404 centrally fixed at both ends inside the connecting pipe 402, a second rotating shaft 405 that passes through the second bearing cylinder 406, and a second docking gear 403 fixed at the outer end of the second rotating shaft 405. The inner end of the second rotating shaft 405 extends into the air guide box 604 and is fixed to the air guide fan blade 601.

[0024] A bottom connecting shell 2 is fixedly connected between the windward component 1 and the connecting component 4 at the bottom. The bottom connecting shell 2 has arc-shaped ear plates 201 on both sides of the top, and the arc-shaped ear plates 201 are fixed to the bottom of the windward duct 102 and the connecting duct 402 respectively.

[0025] An opening and closing component 3 is rotatably connected to the bottom connecting shell 2; The arc-shaped ear plate 201 fits tightly with the bottom contour of the windward duct 102 and the connecting duct 402, which can effectively distribute the force on the bottom connecting shell 2 and ensure that the connection between the bottom connecting shell 2 and the windward duct 102 and the connecting duct 402 is firm and stable. Meanwhile, the bottom connecting shell 2 provides rotational support for the opening and closing assembly 3, allowing the opening and closing assembly 3 to rotate flexibly around the pin 7 via the L-shaped arm 301, making it easy to open the opening and closing assembly 3 for maintenance. When closed, it can achieve a sealed connection with the windward assembly 1 and the connecting assembly 4, ensuring the airtightness of the air supply process.

[0026] An L-shaped arm 301 is fixed to the outer wall of the opening and closing pipe 302. The L-shaped arm 301 is movably connected to the bottom connecting shell 2 by a pin 7. This connection method has a simple structure and flexible rotation. The opening and closing process of the opening and closing component 3 is smooth and can be completed without complicated tools, which greatly improves the convenience of system maintenance. The inner wall of the clean room wall 5 is also equipped with an air guide assembly 6 that communicates with the inner end of the connecting assembly 4; The air guide assembly 6 includes an air guide box 604 and an air guide fan blade 601 driven by an air guide drive component inside the air guide box 604. The outer end of the air guide box 604 is provided with a third flange 602 fixed to the inner wall of the clean room wall 5, and a number of germicidal lamps 603 are installed at equal intervals around the inner wall of the air guide box 604.

[0027] The opening and closing assembly 3 includes an opening and closing pipe 302, a cleaning rotating component rotatably disposed in the middle of the opening and closing pipe 302, a docking assembly with snap-fit ​​sliding connection at both ends of the cleaning rotating component, and an annular filter element 304 sleeved at both ends of the cleaning rotating component. The opening and closing pipe 302 is provided with a groove 317 that communicates with the bottom connecting shell 2; The cleaning rotating component includes a third bearing cylinder 318 centrally fixed inside the opening and closing pipe 302 with several sets of third support arms 320, a rotating cylinder 310 connected to the third bearing cylinder 318, and a brush plate 315 fixed after the rotating cylinder 310 extends out of the third bearing cylinder 318. The brush plate 315 is provided with brush bristles 316 on its side.

[0028] The docking assembly includes a plug shaft 323 inserted into the rotating drum 310, a third docking toothed disc 303 fixed at the end of the plug shaft 323, a snap-fit ​​block 324 fixed on the outer wall of the plug shaft 323, and a lever block 308 fixed on the side wall at the end of the snap-fit ​​block 324. The side of the rotating drum 310 is provided with a sliding groove 321, and the end of the sliding groove 321 is provided with a first through groove 319 extending to the side wall of the rotating drum 310. The latching block 324 slides into the slide groove 321, and the pusher block 308 extends through the first through groove 319.

[0029] The adjustment assembly includes a double ring seat 312 sleeved on the rotating drum 310, a lever 314 fixed to the side of the double ring seat 312, an arc-shaped sealing plate 305 connected to the lever 314 after it extends through the second through groove 322 on the opening and closing pipe 302, a pressing plate 309 fixed on the arc-shaped sealing plate 305, a protruding plate 307 fixed to the outer wall of the opening and closing pipe 302, and a spring 306 connecting the protruding plate 307 and the pressing plate 309. The pusher block 308 extends into the double ring seat 312. The double ring seat 312 is provided with a positioning screw 313. The positioning screw 313 extends through the annular filter element 304 and is locked and fixed by a nut 311.

[0030] The inner diameter and thickness of the windward duct 102, the opening and closing duct 302 and the connecting duct 402 are the same; sealing rubber rings (not shown in the figure) can also be embedded at both ends of the opening and closing duct 302, so as to further achieve a sealed connection between the opening and closing duct 302 and the windward duct 102 and the connecting duct 402 when the opening and closing duct 302 is closed.

[0031] After the opening and closing pipe 302 is sealed and connected to the windward pipe 102 and the connecting pipe 402, the adjusting component on the opening and closing pipe 302 drives the docking component to dock with the windward drive component and the air guide drive component, so as to realize the synchronous rotation of the cleaning rotating component and the air guide fan blade 601.

[0032] Before starting the system, ensure that the new annular filter element 304 has been replaced, and open / close assembly 3. Figure 12 In this state, unscrew nut 311, remove the old annular filter element 304, and fit the new annular filter element 304 onto the rotating drum 310, so that the positioning screw 313 extends through the annular filter element 304 and is locked and fixed with nut 311. Then, operate the adjustment component and press the pressing plate 309 with your finger. The pressing plate 309 compresses the spring 306 between the protruding plate 307 and the pressing plate 309, and at the same time drives the arc-shaped sealing plate 305 to move synchronously (the arc-shaped sealing plate 305 can always cover the second through groove 322 to prevent the airflow inside the opening and closing pipe 302 from flowing out and avoid air leakage during the air supply process). The arc-shaped sealing plate 305 drives the lever 314 to move, and the lever 314 drives the double ring seat 312 sleeved on the rotating drum 310 to slide along the axial direction of the rotating drum 310. As the pusher block 308 extends into the double ring seat 312, the double ring seat 312 slides and pushes the pusher block 308 to move. The pusher block 308 drives the snap block 324 fixed thereto to slide along the slide groove 321 of the rotating drum 310, thereby pushing the insertion shaft 323 to be further inserted into the rotating drum 310, so that the third docking toothed disc 303 will not exceed the opening and closing pipe 302. Then push the opening and closing pipe 302, so that the opening and closing pipe 302 rotates around the pin 7 as the center until the opening and closing pipe 302 closes and fits tightly between the windward pipe 102 and the connecting pipe 402. Complete the sealing and docking of the opening and closing component 3 with the windward component 1 and the connecting component 4; Finally, the pressing plate 309 is released, and under the elastic force of the spring 306, the pressing plate 309 moves and resets. The lever 314 drives the lever 308 to move through the double ring seat 312. The lever 308 drives the plug shaft 323 to move towards both ends of the rotating drum 310, so that the third docking toothed disc 303 exceeds the opening and closing pipe 302, until the third docking toothed disc 303 precisely meshes with the first docking toothed disc 107 of the windward drive component and the second docking toothed disc 403 of the air guide drive component, respectively, completing the power docking of the docking component with the windward drive component and the air guide drive component.

[0033] Specifically, when using it: The core working principle of this cleanroom air conditioning system is based on the coordinated operation of various components to achieve precise airflow introduction, cleaning filtration, sterilization and disinfection, and uniform air distribution from the central air conditioning system. It also features convenient maintenance functions to ensure that the air quality in the cleanroom meets preset cleanliness standards. The specific workflow is described below: When the central air conditioning is turned on, the air from the central air conditioning outlet enters the air duct 102 through the first flange 101 of the air-facing component 1. The sealing ring 108 embedded in the first flange 101 further enhances the sealing at the flange joint, preventing airflow from leaking from the gaps and ensuring air supply efficiency. After the airflow enters the windward duct 102, it impacts the windward fan blades 104 inside the windward duct 102, causing the windward fan blades 104 to rotate around the first rotating shaft 105. The fan blades 104 drive the first rotating shaft 105 fixed thereto to rotate synchronously. The first rotating shaft 105 transmits power to the insertion shaft 323 of the docking assembly through the meshing of the first docking toothed disc 107 on its inner end with the third docking toothed disc 303. The insertion shaft 323 drives the rotating drum 310 to rotate synchronously, thereby driving the entire cleaning rotating component to rotate; Meanwhile, the rotating drum 310 drives the second rotating shaft 405 to rotate through the meshing of the third docking toothed disc 303 and the second docking toothed disc 403 at the other end. The inner end of the second rotating shaft 405 is fixed to the guide fan blade 601, thereby driving the guide fan blade 601 to rotate synchronously, realizing the integrated power linkage of "wind-driven - clean rotation - air-guided drive", which can drive multiple components to operate synchronously by relying solely on the airflow of the central air conditioning. Airflow passes through the annular filter element 304, which filters out harmful impurities such as dust and particulate matter in the air to ensure that the air entering the subsequent pipeline meets the cleanliness requirements. During the rotation of the cleaning rotating parts, the rotating drum 310 drives the brush plate 315 to rotate synchronously, and the bristles 316 on the side of the brush plate 315 rotate accordingly. The bristles 316 are elastic and closely adhere to the side wall of the annular filter element 304, cleaning the annular filter element 304 in real time, preventing dust and impurities from clogging the annular filter element 304, extending the service life of the annular filter element 304, and reducing maintenance costs. Dust and impurities fall through the trough 317 to the bottom connecting shell 2, preventing the accumulated impurities from being carried into the clean room by the airflow and causing secondary pollution. The clean airflow, after being cleaned and filtered, enters the air guide box 604 of the air guide assembly 6 through the connecting pipe 402 of the connecting component 4. At this time, several sets of germicidal lamps 603 installed at equal intervals around the inner wall of the air guide box 604 are activated simultaneously to thoroughly sterilize and disinfect the clean airflow entering the air guide box 604, kill harmful pollutants such as bacteria and microorganisms remaining in the airflow, further improve the air quality of the clean room, and meet the stringent usage requirements of the clean room. Meanwhile, the guide fan blades 601 rotate continuously, guiding the airflow and delivering clean air evenly and over a wide area to the clean room, thus achieving ventilation and air exchange in the clean room. The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
