[0024] It is worth noting that through the combined setting of the structures of the flow splitting assembly part 2, the assembly cylinder 3, the fixed vane 6, the installation shell 18, the wind blocking mechanism, the adjusting mechanism and the stabilizing mechanism, the flow rate in the pipe can be adjusted and controlled according to different requirements. Thus, when ventilating two or more different-sized spaces, the air intake volume in the space can be kept in an equilibrium state, which can, to a certain extent, reduce the power consumption of the subsequent air supply equipment, and can ensure that there is no deviation due to the internal pressure during use, improving the stability of air supply.

[0025] Specifically, the wind blocking mechanism includes: a linkage vane 9 rotatably installed on the surface of the assembly shaft 7, and a wind blocking partition 12 connected to the surface of the adjusting vane 11; wherein, limiting guide grooves 8 are distributed on the surfaces of the fixed vane 6 and the linkage vane 9, limiting rods 10 are distributed on the surfaces of the linkage vane 9 and the adjusting vane 11, and the surface of the limiting rod 10 is slidably connected to the inner wall of the limiting guide groove 8.
