The energy efficiency ratio is the ratio of energy conversion efficiency, the larger the energy efficiency ratio is, the more electric energy is saved, and in the fan with the air valve, the ratio of the air quantity output by the fan to the power of the motor is regarded as the energy efficiency ratio. The conventional air valve used in the livestock and poultry house is a free air valve, and the free air valve cannot actively adjust or control the opening and closing state and the opening degree of the air valve, so that the air valve is opened and closed through the air quantity. However, the free air valve cannot actively adjust the valve port state, and the opening and closing of the valve are realized by the air quantity, so that on one hand, the loss of the air quantity is increased, and the output actual air quantity is small; on the other hand, wind resistance is increased in the opening process, the load is increased, and the power of the motor is increased; because the free air valve can not actively control the opening and closing state of the valve, the output air quantity is damaged and the power is increased, so that the energy efficiency ratio is reduced. That is, the conventional damper has a problem that the performance of the damper is low because the opening and closing state of the damper cannot be actively controlled.

Therefore, in view of the shortcomings of the practical manufacturing and implementation of the scheme, the utility model is modified and improved, and the problem that the energy of the air blower is lower due to the fact that the opening and closing state of the air blower cannot be actively controlled in the prior air blower is solved.
