Multi-rotor ceiling fan device

Abstract

The present invention provides a multi-rotor ceiling fan device comprising a ceiling fan body and a rack body. The ceiling fan body is made of aluminum or stainless steel, and comprises a joining body and a hanging rod. The rack body is made of aluminum or stainless steel, and comprises two or more supporting rods and two or more rotor fans. The multi-rotor ceiling fan utilizes hydromechanics principle to control the rotation angle of wind with rotor fans at two sides so as to generate air convection thrust of different speeds and lead the rack body to rotate, hence saving and stabilizing electric energy, enhancing lifetime of use of each structural unit, and increasing visual advertising effect.

I claim:  
     
         1 . A multi-rotor ceiling fan device, comprising:

         2 . The multi-rotor ceiling fan device as claimed in  claim 1 , wherein said rack body is made of aluminum or stainless steel.  
     
     
         3 . The multi-rotor ceiling fan device as claimed in  claim 1 , wherein said rotor fan comprises a plurality of fan leaves and a fan body.  
     
     
         4 . The multi-rotor ceiling fan device as claimed in  claim 3 , wherein a rotating motor is disposed in said fan body.  
     
     
         5 . The multi-rotor ceiling fan device as claimed in  claim 1 , wherein said ceiling fan body is made of aluminum or stainless steel.  
     
     
         6 . The multi-rotor ceiling fan device as claimed in  claim 1 , wherein said joining body comprises a top shell, a rotating joint disk, and a bottom shell.  
     
     
         7 . The multi-rotor ceiling fan device as claimed in  claim 6 , wherein a through hole is disposed at an upper end of said top shell, and said hanging rod passes through said through hole to connect said joining body.  
     
     
         8 . The multi-rotor ceiling fan device as claimed in  claim 6 , wherein a plurality of fixing holes are disposed on an outer peripheral edge of said rotating joint disk, and said fixing holes can connect sad supporting rods of said rack body to facilitate rotation of said rotor fans.  
     
     
         9 . The multi-rotor ceiling fan device as claimed in  claim 6 , wherein a distributor, a rotation device, a braking device, and a fixing axial tube are disposed on said rotating joint disk.  
     
     
         10 . The multi-rotor ceiling fan device as claimed in  claim 9 , wherein said distributor comprises a voltage body, a carbon brusher, a transformer set, and conducting wires.  
     
     
         11 . The multi-rotor ceiling fan device as claimed in  claim 10 , wherein a plurality of soft protuberances are disposed on said carbon brusher, and said soft protuberances properly contact said voltage body.  
     
     
         12 . The multi-rotor ceiling fan device as claimed in  claim 9 , wherein said rotation device comprises two gears, one being disposed on said fixing axial tube, the other being disposed in said braking device.  
     
     
         13 . The multi-rotor ceiling fan device as claimed in  claim 12 , wherein a soft sleeve is sleeved onto an upper end of a supporting shaft, one of said gears being fixedly disposed on a peripheral edge of said soft sleeve and properly meshing the other one of said gears to provide braking and balanced friction during rotation.  
     
     
         14 . The multi-rotor ceiling fan device as claimed in  claim 9 , wherein said braking device comprises an electric sheet structure and a supporting shaft penetrating through a spring.  
     
     
         15 . The multi-rotor ceiling fan device as claimed in  claim 9 , wherein a bi-directional sleeve is disposed at an upper end of said fixing axial tube to connect said hanging rod.  
     
     
         16 . The multi-rotor ceiling fan device as claimed in  claim 6 , wherein a bottom side of said rotating joint disk is joined with a lamp body.
