Multi-fan assembly with an oscillating structure

Abstract

The present invention relates to a multi-fan assembly with an oscillating structure comprising a base body, a mounting seat, a differential mechanism, an oscillating link system, and a down rod. When the differential mechanism rotates the oscillating system, the base body of the multi-fan assembly and the mounting seat will be caused to oscillate limitedly, so that the airflow rate can be effectively controlled through the self-rotation and the revolutionary oscillation of the member fans.

1 . A multi-fan assembly with an oscillating structure comprising: 
 a base body provided on its periphery with a plurality of oscillating member fans;    a mounting seat assembled on the base body, and a plurality of bearing holes defined on the mounting seat;    a differential mechanism disposed in the mounting seat and including a pivoted axle inserted in one of the bearing holes of the mounting seat and a central spindle inserted another one of the bearing holes;    an oscillating link system pivotally disposed on the mounting seat and controlled by the pivoted axle of the differential mechanism; and    a down rod having an end fixed to a ceiling and another end fixed to the central spindle of the differential mechanism.    
   
   
       2 . The multi-fan assembly with an oscillating structure as claimed in  claim 1 , wherein the differential mechanism includes a positioning disc, a positioning seat, a gear set and a motor, the gear set is disposed between the positioning seat and the positioning disc, and the positioning is locked in the mounting seat.  
   
   
       3 . The multi-fan assembly with an oscillating structure as claimed in  claim 1 , wherein the differential mechanism is of multi-spindle type.  
   
   
       4 . The multi-fan assembly with an oscillating structure as claimed in  claim 1 , wherein the differential mechanism is of double-spindle type.  
   
   
       5 . The multi-fan assembly with an oscillating structure as claimed in  claim 1 , wherein the differential mechanism is of planetary type.
