[0023] 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.

[0024] Please see Figure 1-7 This utility model provides a technical solution: an air circulation device for a cleanroom, including a housing 1, an air inlet chamber 11 and an air outlet chamber 12 inside the housing 1, a first air guide chamber 7 fixedly installed on the air inlet chamber 11, a filter assembly 6 installed on the first air guide chamber 7, the filter assembly 6 including a limiting frame 26, a sliding groove 32 opened on the first air guide chamber 7, the limiting frame 26 sliding within the sliding groove 32, a filter screen 28 fixedly embedded on the limiting frame 26, two sets of mounting blocks 23 fixedly installed on the left and right sides of the first air guide chamber 7, and a fixing rod 24 fixedly installed between the two sets of mounting blocks 23, the front and rear ends of the fixing rod 24 are provided with threaded sections, and a swivel ring 30 is threadedly connected to the threaded section of the fixing rod 24. A baffle 31 is rotatably mounted on the rotating ring 30; a sealing cover 25 is provided on both the front and rear sides of the sliding groove 32, and a rubber sealing gasket 27 is fixedly embedded in the sealing cover 25. A mating groove 29 is opened on both the left and right sides of the sealing cover 25, and the mating groove 29 mates with the baffle 31; the air inlet chamber 11 is fixedly connected to the first air guide pipe 2, and the air outlet chamber 12 is fixedly connected to the second air guide pipe 3. The first air guide pipe 2 and the second air guide pipe 3 are both fixedly connected to the air box 4. Several air guide ports 5 are opened at the bottom of the air box 4; a second air guide chamber 8 is fixedly mounted on the air outlet chamber 12, and the second air guide chamber 8 is fixedly connected to the air outlet pipe 10. The first air guide chamber 7 is fixedly connected to the air inlet pipe 9. A protective net 22 is fixedly installed in both the air outlet pipe 10 and the air inlet pipe 9.

[0025] In use, when air enters the first air chamber 7 through the air inlet duct 9, the filter screen 28 in the filter assembly 6 filters the air. The filtered air then enters the air inlet chamber 11 and then flows through the first air inlet duct 2 and its upper air box 4 into the workshop. Simultaneously, the air in the workshop flows through the second air inlet duct 3 and its upper air box 4 into the air outlet chamber 12, then through the second air inlet chamber 8 into the air outlet duct 10, and finally out to the outside. The protective net 22 protects the components inside the outer casing 1. When the filter screen 28 needs to be replaced, the rotating ring 30 is rotated. Under the action of the threaded section on the fixed rod 24, the rotating ring 30 drives the baffle 31 forward (backward). The mechanism moves until the baffle 31 leaves the sealing cover 25. Under the influence of gravity, the baffle 31 will rotate at a certain angle and will not block the sealing cover 25. Then, the two sets of sealing covers 25 are removed from the first air guide chamber 7. Then, the new limiting frame 26 with the filter screen 28 is slid into the sliding groove 32. At the same time, the old limiting frame 26 is pushed out from the other end of the sliding groove 32, thus realizing the replacement of the filter screen 28. After that, the sealing cover 25 is reinstalled in the designated position. Then, the rotating ring 30 is rotated. With the cooperation of the groove 29 and the baffle 31, the sealing cover 25 is fixed. The rubber sealing gasket 27 embedded in the sealing cover 25 can improve the airtightness.

[0026] A first bracket 15 is provided inside the air inlet chamber 11. A first motor 17 is fixedly installed on the first bracket 15. An inlet fan blade 19 is fixedly mounted on the drive shaft of the first motor 17. A second bracket 16 is provided inside the air outlet chamber 12. A second motor 18 is fixedly installed on the second bracket 16. An outlet fan blade 20 is fixedly mounted on the drive shaft of the second motor 18. Wire mounting holes 21 are provided on both the left and right sides of the outer casing 1.

[0027] In use, the first motor 17 and the second motor 18 start simultaneously. The drive shaft of the first motor 17 drives the intake fan blade 19 to rotate, thereby allowing external air to enter the air intake chamber 11. The drive shaft of the second motor 18 drives the exhaust fan blade 20 to rotate, thereby allowing the workshop air to enter the exhaust chamber 12. The wire mounting hole 21 facilitates the installation of wires.

[0028] Working principle: During use, the first motor 17 and the second motor 18 start simultaneously. The drive shaft of the first motor 17 drives the intake fan blade 19 to rotate, thereby allowing outside air to enter the intake chamber 11. The drive shaft of the second motor 18 drives the exhaust fan blade 20 to rotate, thereby allowing the workshop air to enter the exhaust chamber 12. After the air enters the first air guide chamber 7 from the intake pipe 9, the filter screen 28 in the filter assembly 6 filters the air. The filtered air then enters the intake chamber 11 and then passes through the first air guide pipe 2 and its upper air box 4 into the workshop. At the same time, the air in the workshop enters the exhaust chamber 12 through the second air guide pipe 3 and its upper air box 4, then enters the exhaust pipe 10 through the second air guide chamber 8, and finally exits to the outside. The protective net 22 protects the components inside the outer casing 1.

[0029] When the filter 28 needs to be replaced, rotate the rotating ring 30. Under the action of the threaded section on the fixed rod 24, the rotating ring 30 drives the baffle 31 to move forward (backward) until the baffle 31 leaves the sealing cover 25. Under the action of gravity, the baffle 31 will rotate at a certain angle and will not block the sealing cover 25. Then, remove the two sets of sealing covers 25 from the first air guide chamber 7. Then, slide the new limiting frame 26 with the filter 28 embedded into the sliding groove 32. At the same time, push the old limiting frame 26 out from the other end of the sliding groove 32, thus realizing the replacement of the filter 28. After that, reinstall the sealing cover 25 in the designated position, and then rotate the rotating ring 30. With the cooperation of the mating groove 29 and the baffle 31, the sealing cover 25 is fixed. The rubber sealing gasket 27 embedded in the sealing cover 25 can improve the airtightness. The wire mounting hole 21 can facilitate the installation of wires.

[0030] This design greatly reduces the difficulty of replacing filter 28 and improves the efficiency of replacement.
