Mini fan for computer

Abstract

A mini fan for computer is disclosed, which includes a housing, a motor, self-lubricated axle bearings respectively adapted to the center hole of the motor, and a fan blade unit supported in the self-lubricated axle bearings for smooth rotation upon operation of the motor, the self-lubricated axle bearings being made of high molecular heat resisting compound material or high molecular compound material of low coefficient of friction for the advantages of low manufacturing cost and low operation noise level.

What is claimed is:  
     
         1 . A mini fan for computer comprising: 
 a housing, said housing comprising a receiving open chamber, a motor mount inside said receiving open chamber, and a through hole through the center of said motor mount;    a motor fixedly mounted on said motor mount inside said receiving open chamber, said motor having a center hole coupled to the through hole of said motor mount;    at least one self-lubricated axle bearing respectively adapted to the center hole of said motor, said at least one self-lubricated axle bearing each having a peripheral wall and a center axle hole; and    a fan blade unit, said fan blade unit comprising a hub, a plurality of blades radially arranged around said hub, and an axle axially extended from said center of the hub and inserted through the center axle hole of each of said at least one self-lubricated axle bearing, the center hole of said motor and the through hole of said motor mount for rotation in the center axle hole of each of said at least one self-lubricated axle bearing, upon operation of said motor.    
     
     
         2 . The mini fan for computer as claimed in  claim 1 , wherein said at least one self-lubricated axle bearing is respectively made of high molecular compound material of low coefficient of friction.  
     
     
         3 . The mini fan for computer as claimed in  claim 1 , wherein said at least one self-lubricated axle bearing is respectively made of high molecular heat-resisting compound material.  
     
     
         4 . The mini fan for computer as claimed in  claim 1 , wherein said at least one self-lubricated axle bearing is respectively made of Teflon.
