Ceiling fan structure with detachable dc controller

Abstract

A ceiling fan structure with detachable DC controller includes a canopy having a mounting bracket assembled therein, a filter device assembled in the canopy, a downrod fixed to the mounting bracket at a top end thereof, a bottom end of the downrod passing through the canopy and vertically downward extending, a motor assembled to the bottom end of the downrod, the motor having a shaft, a suspending case enclosing the motor, a DC controller assembled on the suspending case and having a switching circuit and signal wires, each signal wire passing though the suspending case and electrically connected to the motor, the filter device having power wires, each power wire passing through the downrod and electrically connected to the switching circuit of the DC controller, blades fixed around the shaft and the blades rotated by the rotation of the shaft.

What is claimed is: 
     
         1 . A ceiling fan structure with detachable DC controller comprising:
 a canopy having a mounting bracket assembled therein, the mounting bracket configured to fix the canopy to a ceiling;   a filter device assembled in the canopy;   a downrod fixed to the mounting bracket at a top end thereof, a bottom end of the downrod passing through the canopy and vertically downward extending;   a motor assembled to the bottom end of the downrod, the motor having a shaft configured to be driven to rotate;   a suspending case enclosing the motor;   a DC controller assembled on the suspending case and having a switching circuit and a plurality of signal wires, each signal wire passing though the suspending case and electrically connected to the motor, the filter device having a plurality of power wires, each power wire passing through the downrod and electrically connected to the switching circuit of the DC controller; and   a plurality of blades fixed around the shaft, the blades rotated by the rotation of the shaft.   
     
     
         2 . The ceiling fan structure with detachable DC controller as claimed in  claim 1 , wherein the suspending case has a lid detachably assembled thereon, the lid covering the DC controller.
