Description

Technical Field

[0001] This invention relates to the field of cleanroom technology, specifically to a cleanroom with a self-circulating purification fresh air management component. Background Technology

[0002] Cleanrooms are special enclosed spaces that use air filtration systems, airflow control, and environmental parameter adjustments to keep indoor particles, temperature, humidity, and other indicators within strict standard ranges. Their core feature is the use of high-efficiency filters to purify the air and the maintenance of cleanliness through unidirectional or turbulent flow. They are widely used in industries sensitive to dust and microorganisms, such as chip manufacturing, pharmaceutical production, and precision instruments, and are an indispensable infrastructure for modern industrial production.

[0003] To maintain the cleanliness level of a cleanroom, it needs to be professionally cleaned regularly. Some cleanrooms typically have the air inlet located at the top and the air outlet at the bottom, which facilitates the settling and discharge of pollutants and avoids airflow turbulence.

[0004] However, the air outlet is located near the ground in the clean room, which means that when cleaning the air outlet and its components, the cleaning staff have to bend down, which is inconvenient, time-consuming and laborious. In addition, when disassembling the air outlet components, the vibration caused by disassembling the clips or screws may cause impurities on the components to fall, polluting the surrounding environment and increasing the workload of the cleaning staff. Summary of the Invention

[0005] The purpose of this invention is to provide a cleanroom with a self-circulating purification fresh air management component to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clean room with a self-circulating purification fresh air management component, comprising a clean room body, an air intake system connected to the top surface of the clean room body, an air intake module corresponding to the air intake system provided on the inner top surface of the clean room body, an air outlet system provided on the outer side of the clean room body near the bottom, and an air outlet mechanism provided on the left and right sides of the clean room body corresponding to the air outlet system.

[0007] The air outlet mechanism includes a connecting panel, a central slot, a rear seat, an air outlet duct module, a filter box, an opening and closing door, a drive chamber, and a drive mechanism. A set of connecting panels is provided on the bottom left and right sides of the cleanroom body, corresponding to the position of the air outlet system. At least two sets of central slots are provided on the outer side of the connecting panel. A set of rear seats is provided on the inner end of each central slot. An air outlet duct module is provided on the side of the rear seat closest to the inner end of the cleanroom body. A filter box is connected to the end of the air outlet duct module away from the rear seat. Two sets of opening and closing doors are provided at the opening of the central slot. A drive chamber is provided at the upper and lower ends of the central slot. A drive mechanism is provided in each drive chamber.

[0008] By adopting the above technical solution, the air intake system above the cleanroom body and the air outlet system below work together to form a vertical unidirectional airflow organization, which can control the diffusion of pollutants within the cleanroom body. The air outlet mechanism is distributed in different positions within the cleanroom body through multiple independent central slots and air outlet duct modules, which can ensure uniform airflow return, avoid local eddies or dead corners, maintain stable cleanliness, and provide dual filtration through filter cartridges and opening and closing doors. The filter cartridges are directly installed at the end of the air outlet duct module to ensure that the return air is filtered before entering the duct, preventing pollutants from accumulating in the duct, reducing the risk of system contamination, optimizing the airflow organization of the cleanroom body, and improving filtration efficiency.

[0009] Preferably, a set of movable panels is connected to the top of the filter box, a set of filter screens is provided in the middle of the movable panels, and a set of limiting mechanisms is provided at the front, back and bottom of the filter box.

[0010] By adopting the above technical solution, the movable panel can serve as an inspection port for the filter screen. The filter screen can be quickly removed or replaced without disassembling the entire filter box, reducing maintenance time and improving maintenance convenience.

[0011] Preferably, the top of the movable panel is provided with a set of movable shafts, the front and rear ends of the movable shafts are respectively connected to the top of the front and rear ends of the filter box, and a set of movable arms is provided at the positions of the front and rear ends of the movable panel corresponding to the limiting mechanism. The other end of the two sets of movable arms is provided with a set of movable rods on one side of the limiting mechanism.

[0012] By adopting the above technical solutions, the movable shaft, movable arm, and movable rod further improve the design of the movable parts of the filter box, making it more flexible and stable in opening, closing, and locking. The movable shaft serves as a fulcrum, allowing the movable panel to rotate along the movable shaft, enabling quick opening and closing with one hand and facilitating rapid maintenance of the filter screen. When the movable panel is closed, the movable arm drives the movable rod to insert into the limiting mechanism, forming a physical latch to prevent the movable panel from accidentally popping open due to airflow impact.

[0013] Preferably, the limiting mechanism includes a limiting groove, a moving block, a groove, and a spring. A set of limiting grooves is provided at the front and rear ends near the bottom of the filter box. A set of moving blocks is provided at one end of the limiting groove away from the main body of the clean room. A set of grooves is provided at the other end of the moving blocks. A set of springs is connected in the grooves. The other end of the springs is connected to the moving blocks.

[0014] By adopting the above technical solution, the spring provides continuous elastic force, which keeps the moving block in a popping-out tendency, and squeezes and locks the movable rod inserted into the inner end of the limiting groove, realizing the elastic self-locking function. The groove and the movable rod form a tight fit, which can ensure accurate reset every time it closes, avoid misalignment, and the fixing method is convenient and reliable.

[0015] Preferably, each of the two sets of opening and closing doors is provided with a second set of filter screens.

[0016] By adopting the above technical solution, the airflow can be initially filtered.

[0017] Preferably, the upper drive mechanism includes a rotating shaft, a meshing component, a drive arm 1, an auxiliary arm 1, an auxiliary arm 2, a drive arm 2, a drive arm 3, and a drive motor. A set of rotating shafts is provided at both the front and rear ends of the drive compartment. A set of meshing components is provided at the middle of both sets of rotating shafts. A set of drive arms 1 is provided at the top of both sets of rotating shafts. An auxiliary arm 1 is provided at both the front and rear ends of the drive compartment near the two sets of drive arms 1. The front and rear drive arms 1 and auxiliary arms 1 are connected by an auxiliary arm 2. The ends of the front and rear drive arms 1 and auxiliary arms 1 away from the rotating shaft are respectively connected to the top surfaces of the front and rear opening and closing doors. The bottom ends of both sets of rotating shafts extend through into the middle groove and are connected to a drive arm 2. A drive arm 3 is provided at the other end of each drive arm 2. The other end of each drive arm 3 is connected to the top surface of the filter box. A drive motor is connected to the top of the front rotating shaft.

[0018] By adopting the above technical solution, the rotating shaft and meshing parts cooperate to ensure that the components at both ends operate synchronously, avoiding asynchronous opening and closing of the door. The drive arm one, auxiliary arm one and auxiliary arm two form a four-bar linkage mechanism, which converts the rotational motion into the translational motion of the door, realizing the smooth opening and closing of the door and avoiding large vibrations. This shakes off dust and dirt on the door. At the same time, the rotating shaft can also drive the filter box to move vertically through drive arm two and drive arm three, pushing it outward, which is more conducive to cleaning and replacing the filter box.

[0019] Preferably, the meshing member is fan-shaped, and the arc surface is provided with intermeshing protrusions.

[0020] By adopting the above technical solution, the two sets of rotating shafts at the front and rear can be driven to rotate synchronously.

[0021] Preferably, each of the two sets of opening and closing doors has a slot at the middle of its opposite side, the second filter screen is inserted into the slot, and the second filter screen has a buffer layer on both the front and back.

[0022] By adopting the above technical solution, the filter screen 2 is detachably connected to the door, which facilitates subsequent cleaning operations and makes replacement easier.

[0023] Preferably, the rear end of the limiting groove is configured as a heart-shaped channel.

[0024] By adopting the above technical solution, the movement path of the movable rod can be restricted, and the movable panel can be fixed.

[0025] Preferably, the movable panel is slidably connected to the filter screen, and the bottom of the movable panel is provided with a retrieval port.

[0026] By adopting the above technical solution, the movable panel and the filter screen are detachably connected, which facilitates subsequent cleaning operations and makes replacement easier.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention uses two sets of opening and closing doors located at the opening of the central slot and a filter box at the end of the air outlet module. Each of the two sets of opening and closing doors is equipped with a second filter screen. By cooperating with the first filter screen in the filter box, a gradient filtration design is adopted to form a highly efficient dual-stage filtration structure, which can significantly improve the overall filtration efficiency and significantly reduce the filtration resistance. It can effectively extend the service life of the second filter screen and the first filter screen, ensuring excellent purification effect while taking into account energy efficiency and maintenance costs.

[0029] 2. The present invention uses drive chambers located at the upper and lower ends of the central tank. Each drive chamber is equipped with a drive mechanism, which includes a rotating shaft, meshing parts, drive arm one, auxiliary arm one, auxiliary arm two, drive arm two, drive arm three, and drive motor. With their cooperation, drive arm one and auxiliary arm one can drive two sets of opening and closing doors to open synchronously and smoothly, which facilitates the cleaning of filter screen two. Drive arm two and drive arm three can push the filter box outward at the same time, which can optimize the cleaning process, reduce the cleaning intensity, and improve the cleaning efficiency.

[0030] 3. The present invention uses components such as a movable panel, a filter screen, and a limiting mechanism installed inside the filter box. The movable panel and the filter screen are detachably connected, which facilitates the cleaning and replacement of the filter screen. The limiting mechanism fixes the movable panel and controls the posture of the movable panel inside the filter box, preventing the movable panel from accidentally popping open. This can effectively improve the flexibility and stability of the filter box. Attached Figure Description

An air outlet duct module 54 is connected to the side of the rear seat 53 near the inner end of the cleanroom body 1. The air inlet of the air outlet system 3 is connected to the air outlet duct module 54, and the gas in the cleanroom body 1 can be discharged through the air outlet duct module 54. The end of the air outlet duct module 54 away from the rear seat 53 contacts the filter box 55. Two sets of opening and closing doors 56 are provided at the opening of the middle channel 52. A set of drive chambers 57 is opened at the upper and lower ends of the middle channel 52. A set of drive mechanisms 58 is installed in each drive chamber 57.

[0044] Specifically, the air outlet mechanism 5 is distributed in different positions within the cleanroom body 1 through multiple independent central slots 52 and air outlet duct modules 54, which can ensure uniform airflow return, avoid local eddies or dead corners, maintain stable cleanliness, and perform dual filtration through the filter cartridge 55 and the opening and closing door 56. The filter cartridge 55 is directly installed at the end of the air outlet duct module 54 to ensure that the return air is filtered before entering the duct, prevent pollutants from accumulating in the duct, reduce the risk of system contamination, optimize the airflow organization of the cleanroom body 1, and improve filtration efficiency.

[0045] Please see Figures 5-6 A set of movable panels 551 is hinged to the top of the filter box 55. A set of filter screens 552 is installed in the middle of the movable panel 551. The movable panel 551 and the filter screens 552 are slidably connected. The bottom of the movable panel 551 is provided with a pick-up port, through which the filter screens 552 can be picked up or placed. The movable panel 551 and the filter screens 552 are detachably connected, which is beneficial for subsequent cleaning operations and easy to replace. A set of limiting mechanisms 553 is provided at the front, back and bottom of the filter box 55.

[0046] Specifically, the movable panel 551 can serve as an inspection port for the filter screen, allowing for quick removal or replacement of the filter screen 552 without the need to completely disassemble the filter box 55, thus reducing maintenance time and improving maintenance convenience.

[0047] Please see Figures 5-6 A set of movable shafts 5511 is fixedly connected to the top of the movable panel 551. The front and rear ends of the movable shafts 5511 are rotatably connected to the top of the front and rear ends of the filter box 55, respectively, so that they can rotate inside the filter box 55. A set of movable arms 5512 is hinged to the front and rear ends of the movable panel 551 at the positions corresponding to the limiting mechanism 553. A set of movable rods 5513 is connected to the other end of the two sets of movable arms 5512 at the side corresponding to the limiting mechanism 553.

[0048] Specifically, the movable shaft 5511, movable arm 5512, and movable rod 5513 further improve the design of the movable parts of the filter box 55, giving it more flexible and stable opening, closing, and locking functions. The movable shaft 5511 serves as a rotation fulcrum, allowing the movable panel 551 to rotate along the movable shaft 5511, enabling quick opening and closing with one hand and facilitating rapid maintenance of the filter screen 552. When the movable panel 551 is closed, the movable arm 5512 drives the movable rod 5513 to insert into the limiting mechanism 553, forming a physical latch to prevent the movable panel 551 from accidentally popping open due to airflow impact.

[0049] Please see Figure 6 The limiting mechanism 553 includes a limiting groove 5531, a moving block 5532, a groove 5533, and a spring 5534. A set of limiting grooves 5531 is provided at the front and rear ends near the bottom of the filter box 55. The rear end of the limiting groove 5531 is set as a heart-shaped channel, which can limit the movement path of the movable rod 5513 and fix the movable panel 551. A set of moving blocks 5532 is slidably connected to one end of the limiting groove 5531 away from the clean room body 1. A set of grooves 5533 is provided at the other end of the moving block 5532. A set of springs 5534 is connected in the grooves 5533. The other end of the springs 5534 is connected to the moving block 5532.

[0050] Specifically, the spring 5534 provides continuous elastic force, keeping the moving block 5532 in a tendency to pop outward, and pressing and locking the movable rod 5513 inserted into the inner end of the limiting groove 5531 to achieve the elastic self-locking function. The groove 5533 and the movable rod 5513 form a tight fit, which can ensure accurate reset every time it is closed, avoid misalignment, and the fixing method is convenient and reliable.

[0051] Please see Figures 3-4 Each of the two sets of opening and closing doors 56 is equipped with a second set of filter screens 561. Each of the two sets of opening and closing doors 56 has a slot at the middle of the opposite side, into which the second set of filter screens 561 can be inserted. The second set of filter screens 561 has a buffer layer at the front and back. When the two sets of opening and closing doors 56 are closed, the two sets of filter screens 561 can be squeezed against each other through the buffer layer, which can improve the sealing effect and thus achieve a better filtration effect.

[0052] Specifically, the filter screen 561 is detachably connected to the door 56, which facilitates subsequent cleaning operations, makes replacement easy, and allows for preliminary filtration of the airflow.

[0053] Please see Figure 3 , Figure 4 , Figure 7 and Figure 8The upper drive mechanism 58 includes a rotating shaft 581, a meshing member 582, a first drive arm 583, an first auxiliary arm 584, a second auxiliary arm 585, a second drive arm 586, a third drive arm 587, and a drive motor 588. A set of rotating shafts 581 is rotatably connected to both the front and rear ends of the drive compartment 57. A set of meshing members 582 is fixedly connected to the outer middle of each set of rotating shafts 581. The meshing members 582 are fan-shaped, and their arc surfaces are provided with intermeshing teeth, which can drive the two sets of rotating shafts 581 to rotate synchronously. A set of first drive arms 583 is fixedly connected to the outer top of each set of rotating shafts 581. A set of first auxiliary arms 584 is hinged to both the front and rear ends of the drive compartment 57 near the positions of the first drive arms 583. The front and rear drive arms 583 and first auxiliary arms 584 are connected by a set of second auxiliary arms 585, ensuring that the first drive arms 583 and first auxiliary arms 584 always remain parallel. The ends of the first drive arm 583 and the first auxiliary arm 584, away from the rotating shaft 581, are respectively connected to the top surfaces of the front and rear sets of opening and closing doors 56. When the first drive arm 583 and the first auxiliary arm 584 rotate, they can push the opening and closing doors 56 outwards and drive the two sets of opening and closing doors 56 away from each other, exposing the inner end of the middle groove 52. The bottom ends of the two sets of rotating shafts 581 extend through into the middle groove 52 and are fixedly connected to a second drive arm 586. The other end of the second drive arm 586 is hinged to a third drive arm 587. The other end of the third drive arm 587 is connected to the top surface of the filter box 55. The rotation of the rotating shaft 581 can push the filter box 55 to move by the second drive arm 586 and the third drive arm 587. The top end of the front rotating shaft 581 is connected to a drive motor 588. The drive shaft of the drive motor 588 is fixedly connected to the top end of the front rotating shaft 581 and can drive the front rotating shaft 581 to rotate.

[0054] Specifically, the rotating shaft 581 and the meshing part 582 work together to ensure that the components at both ends operate synchronously, avoiding asynchronous opening and closing of the door 56. The drive arm 1 583, the auxiliary arm 1 584 and the auxiliary arm 2 585 form a four-bar linkage mechanism, which converts the rotational motion into the translational motion of the door 56, realizing the smooth opening and closing of the door 56, avoiding large vibrations, and shaking off dust and dirt on the door 56. At the same time, the rotating shaft 581 can also drive the filter box 55 to move vertically through the drive arm 2 586 and the drive arm 3 587, pushing it outward, which is more conducive to cleaning and replacing the filter box 55.

[0055] This invention provides a cleanroom with a self-circulating purification fresh air management component. The invention utilizes two sets of opening and closing doors 56 located at the opening of the central trough 52, and a filter box 55 at the end of the air outlet duct module 54. Each of the two sets of opening and closing doors 56 contains a second filter screen 561, which, in conjunction with the first filter screen 552 in the filter box 55, employs a gradient filtration design to form a highly efficient two-stage filtration structure. This significantly improves overall filtration efficiency while significantly reducing filtration resistance, effectively extending the service life of both the second filter screen 561 and the first filter screen 552. This ensures excellent purification performance while balancing energy efficiency and maintenance costs. Furthermore, the invention incorporates drive chambers 57 located at the upper and lower ends of the central trough 52, each containing a drive mechanism 58. Each drive mechanism 58 includes a rotating shaft 581, a meshing component 582, a first drive arm 583, a first auxiliary arm 584, and a second auxiliary arm 585. The components, including drive arm 2 586, drive arm 3 587, and drive motor 588, work together to drive two sets of opening and closing doors 56 to open synchronously and smoothly via drive arm 1 583 and auxiliary arm 1 584, facilitating the cleaning of filter screen 2 561. Drive arm 2 586 and drive arm 3 587 can simultaneously push the filter box 55 outwards, optimizing the cleaning process, reducing cleaning intensity, and improving cleaning efficiency. The movable panel 551, filter screen 1 552, and limiting mechanism 553, all located within the filter box 55, allow for detachable connection between the movable panel 551 and filter screen 1 552, facilitating cleaning and replacement of filter screen 1 552. The limiting mechanism 553 secures the movable panel 551, controlling its posture within the filter box 55 and preventing accidental pop-out, effectively improving the flexibility and stability of the filter box 55.
