[0002] A cleanroom is a sealed space with well-controlled parameters such as air cleanliness. The cleanroom's return air structure can filter and purify the air, maintaining a good air environment inside the cleanroom. It mainly consists of an air pump, air inlet, air outlet, and filter structure.

[0003] Chinese utility model patent CN207219427U discloses a cleanroom return air structure, including a fan. The bottom of the gooseneck tube is connected to a return air inlet via a flexible hose. An adjustment mechanism is located below the fan, comprising an annular plate, a circular plate, a vertical cylinder, a locking block, and a rod. The top of the annular plate is fixedly connected to the bottom of the circular plate, and the inner side of the circular plate is fixedly connected to the lower outer wall of the gooseneck tube. A rod is fixedly connected to the top of the circular plate, and a vertical cylinder fixedly connected to the top plate is fixedly connected to the outer side of the rod. A locking block is movably connected to the bottom annular groove of the annular plate, and the bottom of the locking block is fixedly connected to the top of the return air inlet. This utility model relates to the field of cleanroom technology. Through the cooperation between the return air inlet, bolts, and locking blocks, the height and lateral angle of the return air inlet are adjusted, solving the problem that the position of the return air inlet in existing structures is fixed, making it inconvenient to adjust according to the actual environment, thus leading to poor air circulation or dead corners.

[0004] Based on existing solutions and actual production and processing, the existing adjustable cleanroom return air structure, through complex structural adjustments to the height of the air inlet hood, results in dust re-adheding from the collection structure onto the filter structure after cleaning, affecting its use. Therefore, we propose an adjustable cleanroom return air structure to solve the aforementioned problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Please refer to Figures 1-6The existing adjustable cleanroom return air structure, when used, involves adjusting the height of the air inlet hood 6 through a complex structure. After cleaning the dust on the filter surface, the dust will re-adhere to the filter structure from the collection structure when the system is used again, affecting its use. In order to solve this technical problem, this embodiment discloses the following technical content.

[0029] An adjustable cleanroom return air structure includes a mounting cover 1, an air pump 2, an air outlet pipe 3, a filter shell 4, an air inlet hose 5, an air inlet hood 6, a counterweight 7, a first motor 8, a winding roller 9, a hanging rope 10, a collection box 11, an electric telescopic rod 12, a cover plate 13, a filter plate 14, a second motor 15, a screw 16, a limiting rod 17, a cleaning plate 18, a first activated carbon plate 19, and a second activated carbon plate 20.

[0030] Mounting cover 1 is installed on the top wall structure of the clean room. Filter shell 4 is installed inside mounting cover 1. Air outlet pipe 3 is fixed to the output end of air pump 2. Filter shell 4 is connected to the input end of air pump 2. Air inlet hose 5 is fixed to the bottom end of filter shell 4. Air inlet cover 6 is fixed to the bottom end of air inlet hose 5. Both the front and rear ends of air inlet cover 6 are porous structures. Height control components for adjusting the air inlet height are installed on air inlet cover 6.

[0031] The height control assembly includes a counterweight 7, a first motor 8, a winding roller 9, and a hoisting rope 10. The first motor 8 is fixed to the inner top wall of the mounting cover 1, the winding roller 9 is fixed to the output end of the first motor 8, and the hoisting rope 10 is wound around the outer side of the winding roller 9. The counterweight 7 is fixed to the upper surface of the air inlet cover 6.

[0032] Start the air pump 2. Under the action of the air pump 2, the air in the clean room passes through the holes of the air inlet hood 6 and enters the air inlet hose 5 and flows to the filter shell 4. After being filtered by the filter plate 14, the first activated carbon plate 19 and the second activated carbon plate 20, it flows to the air outlet pipe 3. The dust and impurities in the air remain on the filter surface of the filter plate 14 and return to the clean room. Large impurities in the air are prevented from entering the interior of the air inlet hose 5 through the holes at the outer end of the air inlet hood 6.

[0033] When the height of the air inlet hood 6 needs to be adjusted, the first motor 8 is started. The first motor 8 drives the winding roller 9 to rotate clockwise or counterclockwise, thereby winding or releasing the hanging rope 10, and raising or lowering the air inlet hood 6 to adjust the height of the air inlet hood 6. The bottom end of the hanging rope 10 is fixedly connected to the counterweight 7, and the hanging rope 10 is installed on the rear side, front side and left side of the top of the counterweight 7. By extending the three sets of hanging ropes 10 to different lengths, the air inlet hood 6 can be tilted. When tilting the air inlet hood 6, the air intake hose 5 is slightly bent.

[0034] An electric telescopic rod 12 is fixed inside the collection box 11. A cover plate 13 is installed on the outer end of the collection box 11 via a hinge. A second motor 15 is fixed on the front side of the filter shell 4, and a screw 16 is fixed on the output end of the second motor 15. Limiting rods 17 are fixed on both the front and rear inner walls of the filter shell 4. A cleaning plate 18 is threadedly connected to the outer end of the screw 16.

[0035] When the cleaning plate 18 is located at the very end of the filter housing 4, the electric telescopic rod 12 is activated. The top of the electric telescopic rod 12 rises and opens the cover plate 13. Then, the second motor 15 is activated, which drives the screw 16 to rotate, causing the cleaning plate 18 to move back and forth on the filter surface of the filter plate 14 to clean the filter surface of the filter plate 14. Impurities and dust fall into the collection box 11. After the dust cleaning work is completed, the cleaning plate 18 moves to the very end of the filter housing 4, the electric telescopic rod 12 retracts, and the cover plate 13 covers the collection box 11 again to prevent the collected dust from flowing out again.

[0036] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. Please refer to [link / reference]. Figures 1-6 The existing adjustable cleanroom return air structure makes it inconvenient to remove and clean impurities. In order to solve this technical problem, this embodiment discloses the following technical content;

[0037] The filter housing 4 has a collection box 11 running through it. The bottom of the collection box 11 is fixedly connected to the top wall structure of the clean room by screws. When it is necessary to remove impurities for processing, remove the screws used to connect the collection box 11 and the top wall of the clean room, and then pull the collection box 11 out downwards.

[0038] The above completes a series of operations for the adjustable cleanroom return air structure. Any content not described in detail in this specification is prior art known to those skilled in the art.
