The dividing column 440 provides additional support for the connecting frame 301, enhancing the structural rigidity of the entire air supply ceiling. At the same time, it increases the space for opening the second avoidance hole 411. The through hole on the dividing column 440 allows the first reinforcing rod 431 to pass through, improving the integrity of the air distribution hood 400.

[0049] Preferably, the air distribution member is an air distribution film 420. The air distribution film 420 is usually made of lightweight materials, which helps to reduce the weight of the entire air supply ceiling. The air distribution film 420 can effectively distribute air evenly throughout the air supply area, reducing the unevenness of air flow and improving the air purification effect. The surface of the air distribution film 420 is usually smooth, making it easy to clean and maintain, which helps to keep the hygiene and performance of the air supply ceiling. The air distribution film 420 can be customized with different colors and transparencies according to needs to adapt to different interior decoration styles and requirements. Of course, other components capable of air distribution, such as an air distribution net, can also be used as the air distribution member.

A receiving edge 340 that receives the bottom side of the air distribution hood 400 is clamped in the first clamping groove 331. When the air distribution hood 400 is placed into the connecting frame 301, the receiving edge 340 directly receives the edge of the bottom side of the air distribution hood 400 (fixed frame 410), and thus the air distribution hood 400 can be connected to the base 300 conveniently and quickly. Specifically, the receiving edge 340 and the fixed frame 410 can also be fixedly connected by bolts, welding, or gluing, etc.

[0051] Preferably, as Figure 9 and Figure 10 shown, a second clamping groove 332 is formed on the inner bottom wall of the connecting frame 301 of the base 300.
