[0017] 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.

[0018] This utility model provides, for example Figures 1-4 The ventilation device shown includes a housing 1, a rotating cylinder 3, and an adjustment mechanism. The housing 1 houses the ventilation mechanism for ventilating the cleanroom. The rotating cylinder 3 is rotatably connected to the outer wall of the housing 1. A fixed box 5 is fixedly connected to the side of the rotating cylinder 3 away from the housing 1. A guide plate 6 is rotatably mounted inside the fixed box 5. The adjustment mechanism is located outside the rotating cylinder 3 and is used to adjust the guide plates 6. Multiple guide plates 6 are arranged at intervals. The guide plates 6 control the airflow direction of the ventilation mechanism. The rotation of the rotating cylinder 3 drives the guide plates 6 to rotate, increasing the airflow adjustment angle in conjunction with the rotation of the guide plates 6. This allows for different locations of equipment in the cleanroom to be used. In specific use, the ventilation mechanism ventilates the cleanroom, and the adjustment mechanism adjusts the angle of the guide plates 6 to cover blind areas. Adjusting the angle of the guide plates 6 directs the airflow to impact the top of the heat source, suppressing rising airflow and preventing particulate contamination of the upper clean area of ​​the cleanroom.

[0019] One aspect of the adjustment mechanism includes a rotation locking structure and an angle adjustment structure. The angle adjustment structure includes a rotating shaft 17 and a gear 16. The rotating shaft 17 is rotatably connected to the inner wall of the fixed box 5. The guide plate 6 is fixedly sleeved on the outer wall of the rotating shaft 17. The gear 16 is fixedly sleeved on the outer wall of the rotating shaft 17. A rack 15 is slidably connected to the inner wall of the fixed box 5. The rack 15 is slidably connected to the outer wall of the fixed box 5. A locking assembly is provided on the outside of the rack 15. The locking assembly includes a threaded rod 18 and a square plate 4. The threaded rod 18 is fixedly connected to the outer wall of the rack 15. The square plate 4 is movably sleeved on the outer wall of the threaded rod 18. A knob 19 is threadedly sleeved on the outer wall of the threaded rod 18. A gear 16 is provided on the outside of each guide plate 6. Multiple gears 16 are meshed with the rack 15. A groove is provided on the outer wall of the fixed box 5. The rack 15 can move vertically along the groove. The knob 19 rotates and moves along the threaded rod 18. When the square plate 4 is moved by the knob 19, the rotating shaft 17 rotates, causing the guide plate 6 to rotate around the rotating shaft 17, thus adjusting the angle of the guide plate 6. The inner wall of the square plate 4 has a vertical anti-slip pad, and the square plate 4 is in contact with the outer wall of the fixing box 5 through the anti-slip pad. The position of the rack 15 is fixed by the friction between the square plate 4 and the outer wall of the fixing box 5. In specific use: when it is necessary to adjust the angle of the guide plate 6, the worker rotates the knob 19 to release the pressure of the knob 19 on the square plate 4. The worker pulls the knob 19, and the knob 19 drives the rack 15 to move through the threaded rod 18. The rack 15 drives the rotating shaft 17 to rotate through the gear 16, and the rotating shaft 17 drives the guide plate 6 to rotate, thus achieving the purpose of adjusting the up and down wind direction angle of the guide plate 6. The worker rotates the knob 19, and the knob 19 presses the square plate 4. The rack 15 is fixed by the friction between the square plate 4 and the fixing box 5, thus fixing the angle of the guide plate 6.

[0020] On the other hand, the rotary locking structure includes a limiting plate 2 and a limiting block 10. The limiting plate 2 is fixedly sleeved on the outer wall of the housing 1, and the limiting block 10 is snapped into the inner wall of the limiting plate 2. An elastic component is provided on the outer wall of the limiting block 10. The elastic component includes a fixing plate 13 and a circular rod 11. The fixing plate 13 is fixedly connected to the outer wall of the housing 1, and the circular rod 11 is slidably connected to the inner wall of the fixing plate 13. A spring 12 is fixedly connected between the limiting block 10 and the fixing plate 13. A pull rod 14 is fixedly sleeved on the outer wall of the circular rod 11. The outer wall of the limiting plate 2 has multiple vertical slots. The rotating cylinder 3 is fixed by the snapping of the slots with the limiting block 10. The angle of the rotating cylinder 3 can be coarsely adjusted by the limiting block 10 and the limiting plate 2. The rotation of the rotating cylinder 3 drives the guide plate 6 to rotate horizontally. The rotation of the guide plate 6 increases the airflow direction adjustment angle. The spring 12 presses the limiting block 10, so that the limiting block 10 is always engaged with the limiting plate 2. In specific use: when the worker needs to adjust the angle of the rotating cylinder 3, he pulls the pull rod 14. The pull rod 14 drives the limiting block 10 to move through the circular rod 11 until the limiting block 10 is no longer engaged with the limiting plate 2. The worker then rotates the rotating cylinder 3. The rotating cylinder 3 drives the guide plate 6 to rotate through the fixing box 5 to adjust the airflow direction. After the adjustment is completed, the worker releases the pull rod 14. The spring 12 returns to its original position and drives the limiting block 10 to move. The limiting block 10 is engaged with the outside of the limiting plate 2, thus achieving the purpose of fixing the angle of the rotating cylinder 3.

[0021] In addition, the ventilation mechanism includes a grille 9 and a filter plate 7. The grille 9 is fixedly connected to the inner wall of the housing 1. A ventilation fan 8 is installed on the outside of the grille 9. The filter plate 7 is fixedly connected to the inner wall of the housing 1. The filter plate 7 blocks particulate dust. The filter plate 7 is equipped with absorbent cotton to prevent excessive humidity inside the workshop. The ventilation fan 8 forms airflow to ventilate the inside of the workshop.
