[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1 to 3As shown, a ventilation device for a cleanroom in one embodiment of this utility model includes an air inlet pipe 1, an air intake fan 11 installed inside the air inlet pipe 1, and a filter device 4 detachably installed at one end of the air inlet pipe 1 near the air intake fan 11. A third groove 14 is formed on the inner wall of the air inlet pipe 1, penetrating the lower wall of the air inlet pipe 1. An air guide assembly is slidably connected inside the third groove 14, and the air guide assembly is used to guide the air generated when the air intake fan 11 rotates out of the air inlet pipe 1.

[0031] Specifically, when cleaning dust, particles and other pollutants from the intake fan 11, insert the air guide assembly into the third slot 14. After cleaning, start the intake fan 11, and the pollutants that fall into the intake pipe 1 can be discharged through the air guide assembly.

[0032] To achieve the above objectives, such as Figures 3 to 7 As shown, the air guiding assembly includes an air guide duct 3, which is slidably connected within the third groove 14. The air guide duct 3 has an air inlet 32 ​​that matches the inner wall of the air inlet pipe 1. Specifically, when cleaning the intake fan 11, the air guide duct 3 is inserted into the third groove 14, with the opening of the air guide duct 3 abutting against the bottom wall of the third groove 14. The rear wall of the air guide duct 3 isolates the air inlet pipe 1, preventing dust, particles, and other contaminants from the intake fan 11 from spreading within the air inlet pipe 1. After cleaning, the intake fan 11 is activated. The intake fan 11 draws external air and directs it to the air guide duct 3. The air flows into the air guide duct 3 from the air inlet 32 ​​and then exits from the opening of the air guide duct 3 outside the air inlet pipe 1, preventing it from flowing into the cleanroom and thus protecting the cleanroom.

[0033] It is worth noting that, since a third groove 14 is provided on the intake pipe 1, the third groove 14 needs to be sealed during normal use. Furthermore, a sealing plate 31 is welded to one end of the air duct 3 located inside the third groove 14, and the sealing plate 31 matches the third groove 14. During normal operation, the sealing plate 31 seals the third groove 14, preventing gas from the intake pipe 1 from flowing out from the third groove 14.

[0034] Furthermore, a pair of snap-fit ​​blocks 311 are integrally formed on the opposite sidewalls of the sealing plate 31, and a fourth groove 15 matching the snap-fit ​​blocks 311 is provided on the lower pipe wall of the air inlet pipe 1. Specifically, when the sealing plate 31 seals the third groove 14, the snap-fit ​​blocks 311 are snapped into the fourth groove 15, so the air guide pipe 3 will not fall out of the third groove 14.

[0035] To ensure the air duct 3 is more stable within the third groove 14 and to prevent the negative pressure generated during airflow in the intake pipe 1 from drawing the air duct 3 into the intake pipe 1, a rubber layer is wrapped around the snap-fit ​​block 311. When the snap-fit ​​block 311 is snapped into the fourth groove 15, the deformation and pressure of the rubber layer further stabilize the air duct 3.

[0036] In addition, a fifth groove 16 matching the snap-fit ​​block 311 is provided on the wall of the air intake pipe 1. Both the fourth groove 15 and the fifth groove 16 are connected to the third groove 14. Specifically, when cleaning the air intake fan 11, the snap-fit ​​block 311 snaps into the fifth groove 16, so that the air guide pipe 3 is fixed to the bottom wall of the third groove 14. This eliminates the need to keep lifting the air guide pipe 3, making it easier for staff to clean the air intake fan 11.

[0037] Furthermore, a second magnet 312 is embedded in the sealing plate 31. The second magnet 312 is attracted to the bottom wall of the third trough 14, making the air duct 3 more stable.

[0038] like Figure 5 As shown, it is important to note that, in order to ensure that all dust, particles, and other pollutants in the intake pipe 1 after cleaning the intake fan 11 can be discharged through the duct 3, when the sealing plate 31 is attached to the bottom wall of the third tank 14, the inner diameter of the air inlet 32 ​​coincides with that of the intake pipe 1, and the front and rear inner walls of the duct 3 are flush with the front and rear inner walls of the intake pipe 1. The air generated by the rotation of the intake fan 11 is directly blown into the duct 3 from the air inlet 32. By exhausting all the air containing pollutants in the intake pipe 1 through the duct 3, the air quality entering the cleanroom can be guaranteed.

[0039] When replacing filter 4, simply repeat the above steps.

[0040] In the prior art, the filter device 4 is usually fixed to the inlet of the air intake pipe 1 with bolts. Replacing the filter device 4 requires removing the bolts, which is very inconvenient. To facilitate the replacement of the filter device 4, such as... Figures 2 to 4 As shown, the ventilation equipment of the clean room also includes a protective plate 2, which has through holes 21 and a loading frame 23 integrally formed on the protective plate 2. The filter device 4 is snapped into the loading frame 23, and the air inlet pipe 1 has a second groove 13 that matches the loading frame 23.

[0041] Specifically, when replacing the filter device 4, the protective plate 2 is pulled outward, and the loading frame 23 is pulled out from the second tank 13, so that the filter device 4 can be taken out from the loading frame 23, which makes it easy to replace the filter device 4.

[0042] In addition, when the loading frame 23 is inserted into the second groove 13, the second groove 13 is sealed, which can ensure that the air entering the air inlet pipe 1 is filtered by the filter device 4, thereby improving the air quality in the clean room.

[0043] Furthermore, such as Figure 8As shown, to prevent the protective plate 2 from detaching from the air intake pipe 1, a sliding post 22 is integrally formed on the protective plate 2. A first groove 12 matching the sliding post 22 is provided on the air intake pipe 1, and a first magnet 121 is embedded within the first groove 12. Specifically, when the loading frame 23 is inserted into the second groove 13, the sliding post 22 is also inserted into the first groove 12. The first magnet 121 within the first groove 12 attracts the sliding post 22, thus stabilizing the protective plate 2.

[0044] When using, such as Figures 3 to 7 As shown, lift the air duct 3 upwards. When the snap-fit ​​block 311 snaps into the fifth slot 16, the second magnet block 312 also adheres to the bottom wall of the third slot 14. Pull out the protective plate 2 to clean the intake fan 11. Because of the obstruction of the air duct 3, dust, particles, and other pollutants falling from the intake fan 11 will not enter the clean room. After cleaning, start the intake fan 11. When the air circulates in the intake pipe 1, it carries the dust, particles, and other pollutants falling from the intake fan 11 into the air duct 3 through the air inlet 32, and then discharges them into the air.

[0045] After the pollutants in the air inlet pipe 1 are discharged, pull down the air guide pipe 3. When the snap-fit ​​block 311 is snapped into the fourth trough 15, the sealing plate 31 seals the third trough 14. The filter device 4 is installed in the sliding column 22. Then the protective plate 2 is fixed on the air inlet pipe 1. Start the air intake fan 11 to deliver air to the clean room.
