Fan housing

Abstract

A fan housing for surrounding the rotor of a fan. The fan housing has a first frame and a second frame. The first frame includes at least one extending part with a first engaging member. The second frame includes a guide slot and a second engaging member corresponding to the first engaging member to enable the first and second frames to be detachably assembled together.

1 . A fan housing comprising: 
 a first frame comprising at least one extending part with a first engaging member;    a second frame comprising a guide slot and a second engaging member corresponding to the first engaging member to enable the first and second frames to be detachably assembled together.    
   
   
       2 . The fan housing as claimed in  claim 1 , further comprising a stator base disposed in the second frame, and a plurality of connecting parts for connecting the stator base and the second frame.  
   
   
       3 . The fan housing as claimed in  claim 1 , further comprising at least one rib provided on a side wall of the guide slot.  
   
   
       4 . The fan housing as claimed in  claim 1 , wherein the first engaging member and the second engaging member are an engaging hole and a protrusion, respectively.  
   
   
       5 . The fan housing as claimed in  claim 1 , wherein the first and second frames are both formed by injection molding, pressing or cutting.  
   
   
       6 . The fan housing as claimed in  claim 1 , wherein the extending part extends from a periphery of the first frame.  
   
   
       7 . The fan housing as claimed in  claim 1 , wherein the second engaging member comprises an inclined surface.  
   
   
       8 . The fan housing as claimed in  claim 1 , wherein the guide slot and the second engaging member are formed at an outer surface of the second frame.  
   
   
       9 . The fan housing as claimed in  claim 1 , wherein the first frame is a top cover of the fan housing and provided with an air inlet having a block to prevent a backflow.  
   
   
       10 . The fan housing as claimed in  claim 9 , wherein the block of the air inlet is straight.  
   
   
       11 . The fan housing as claimed in  claim 1 , wherein the second frame is a base of the fan housing, and the first and second frames are assembled to form an air outlet.  
   
   
       12 . The fan housing as claimed in  claim 11 , wherein the second frame comprises an opening serving as an air inlet.  
   
   
       13 . A fan comprising: 
 a first frame comprising at least one extending part with a first engaging member;    a second frame comprising a guide slot and a second engaging member corresponding to the first engaging member to enable the first and second frames to be detachably assembled together; and    a rotor mounted in a space surrounded by the first and second frames.    
   
   
       14 . The fan as claimed in  claim 13 , further comprising at least one rib provided on a side wall of the guide slot.  
   
   
       15 . The fan as claimed in  claim 13 , wherein the first and second engaging members are a engaging hole and a protrusion, respectively.  
   
   
       16 . The fan as claimed in  claim 13 , wherein the extending part extends from a periphery of the first frame.  
   
   
       17 . The fan as claimed in  claim 13 , wherein the second engaging member is provided on an inner wall of the guide slot.  
   
   
       18 . The fan as claimed in  claim 13 , wherein the second engaging member comprises an inclined surface.  
   
   
       19 . The fan as claimed in  claim 13 , wherein the guide slot and the second engaging member are disposed at an outer surface of the second frame.
