Abstract
The invention relates to an operating room air purifying system. An air supplying motor array is used for accelerating supplied fresh air by a first air supplying component. The accelerated fresh air passes through a purifying component and enters an operating room. Due to the fact that the fresh air is accelerated by the air supplying motor array, the power and the size of a fresh air motor are reduced. Meanwhile, the purifying component is tightly attached to the lower side of the air supplying motor array, so that the whole system is small in occupied space and manufacturing cost is correspondingly reduced. Each motor of the air supplying motor array is controlled to switch on and off by a main control unit, so that part of motors can be kept switched on by the air supplying motor array according to use conditions, and electric energy consumed by the purifying system is saved. The motor which is selected to be switched on can be determined corresponding to one air outlet, so that wind energy can be effectively used and the energy consumption rate of the whole system is reduced. Each component of the operating room air purifying system is an independent component, so that power can be supplied independently by different external power sources. Therefore, according to the specific working conditions, certain components can be switched on by the purifying system and electric energy can be further saved.
