[0004] The cited patent absorbs and discharges the turbid air inside the cowshed body through an exhaust fan, thereby replacing the air inside the cowshed body. However, because there are impurities such as dust, cow hair, mosquitoes and food debris inside the cowshed, these impurities can easily block the air outlet on the diversion pipe, thereby affecting air circulation; at the same time, the exhaust fan of the cited patent is in a single and fixed position, and it is impossible to carry out all-round air circulation and discharge, and the air circulation effect is not good.
