[0001] This utility model relates to the field of air purification technology, and in particular to a multi-angle airflow guiding device for a cleanroom air outlet. Background Technology

[0002] Cleanroom air supply refers to the process of delivering clean air, which has undergone high-efficiency filtration, into a cleanroom in a specific manner to maintain the required high cleanliness, temperature, humidity, and pressure conditions. A cleanroom is a specially designed space designed to provide a highly pure working environment by controlling the concentration of particulate matter in the air. Existing cleanroom air outlets usually only supply air in a fixed direction and are not convenient for multi-angle adjustment. This may result in insufficient airflow or dead zones in some areas, thus affecting the overall cleanliness of the cleanroom.

[0003] Therefore, it is necessary to design a multi-angle airflow guiding device for cleanroom air outlets that can swing up and down and back and forth to reduce dead zones and improve the uniformity of air distribution. Utility Model Content

Detailed Implementation

[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0020] A multi-angle airflow guiding device for cleanroom air outlets, such as Figures 1-3 As shown, the device includes a ventilation duct 1, a first filter screen 2, a fan 3, a slider 4, a placement frame 5, a high-efficiency filter 6, a support frame 7, a hose 8, an adjustment component, and a swing component. The first filter screen 2 is snapped onto the left side of the ventilation duct 1. The first filter screen 2 has a gripping groove on its upper part for easy gripping. Two fans 3 are installed inside the ventilation duct 1. Two sliders 4 are slidably snapped onto the middle of the placement frame 5. The placement frame 5 is connected between the sliders 4. The placement frame 5 has handles on both the front and back for easy gripping. The high-efficiency filter 6 is placed inside the placement frame 5. The support frame 7 is connected to the lower right side of the ventilation duct 1. The hose 8 is connected to the right side of the ventilation duct 1. The hose 8 has a corrugated structure. The adjustment component is provided on the support frame 7, and the swing component is provided on the adjustment component.

The air outlet frame 9 is rotatably connected to the right side of the support frame 7. The air outlet frame 9 is connected to the hose 8. The first motor 10 is connected to the lower right side of the support frame 7. The missing gear 11 is connected to the output shaft of the first motor 10. Two bevel gears 12 are connected to the lower part of the air outlet frame 9. Both bevel gears 12 mesh with the missing gear 11. The second filter screen 13 is slidably engaged on the left side of the air outlet frame 9.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, it also includes a swing assembly, which includes a second motor 14, an eccentric wheel 15, a first connecting rod 16, a pull rod 17, swing plates 18, and a second connecting rod 19.
