[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , a chicken coop ventilation and air exchange device of the present utility model, includes an exhaust duct 1. A control duct 2 is rotatably installed at the air inlet end of the exhaust duct 1. By directly rotating the control duct 2, the air flow layer discharged inside the chicken coop can be adjusted to control the heights of the hot and cold layers and the fresh air layer inside the chicken coop. A protection duct 3 is installed at the exhaust end of the exhaust duct 1. The inner diameter of the protection duct 3 is larger than the outer diameter of the exhaust duct 1. The exhaust duct 1 and the protection duct 3 are connected by several first connecting shafts 4. A wind deflector 5 is arranged inside the protection duct 3. The wind discharged from the exhaust duct 1 is discharged upward through the gap between the protection duct 3 and the exhaust duct 1, and the wind discharged from the exhaust duct 1 is discharged downward through the gap between the wind deflector 5 and the exhaust duct 1. The wind deflector 5 can effectively prevent the outside wind from blowing into the chicken coop. The diameter of the wind deflector 5 is larger than the inner diameter of the exhaust duct 1 and smaller than the inner diameter of the protection duct 3. The protection duct 3 and the wind deflector 5 are connected by several second connecting shafts 6.
