Fan with multi-directional winds

Abstract

A fan with multi-directional winds having at least two fan units vertically stacked and a shaft mounted between the two fan units. The two fan units are integrally incorporated via the shaft, and different directions of air movement are provided through adjustment with the shaft as the pivot, such that multi-directional fixed wind sources are provided so as to increase the operation range of the fan.

1 . A fan with multi-directional wind, comprising 
 at least two fan units stacked vertically; and    a shaft disposed between said two fan units, wherein said two fan units being integrally formed via said shaft, such that different directions of air movement off said fan units being adjusted with said shaft as pivot.    
   
   
       2 . The fan with multi-directional wind as in  claim 1 , wherein said fan unit comprises a box body having a motor and a plurality of blades driven by said motor disposed therein.  
   
   
       3 . The fan with multi-directional wind as in  claim 2 , wherein said box body consists of a top wall, a bottom wall, a right wall, a left wall, a front side and a rear side, with said front side and said rear side being open.  
   
   
       4 . The fan with multi-directional wind as in  claim 3 , wherein said front side and said rear side are further disposed with a fan guard respectively.  
   
   
       5 . The fan with multi-directional wind as in  claim 1 , wherein a base is further disposed underneath the fan unit stacked at the bottommost.  
   
   
       6 . The fan with multi-directional wind as in  claim 5 , wherein a shaft is disposed between said fan unit stacked at the bottommost and said base, and wherein said shaft is for integrally forming said fan unit stacked at the bottommost and said base.  
   
   
       7 . The fan with multi-directional wind as in  claim 5 , wherein said fan unit stacked at the bottommost and said base are integrally formed.  
   
   
       8 . The fan with multi-directional wind as in  claim 1 , wherein through holes are disposed in said shaft for power wires of said fan units to go through.  
   
   
       9 . The fan with multi-directional wind as in  claim 1 , wherein said fan is further disposed with a switch assembly for turning on, turning off or switching speeds of said motors in said fan units.
