Fan

Abstract

A fan includes a motor, two frames, an impeller and a housing assembly. The two frames are coupled with an outer periphery of the motor and are engaged with each other by way of fastening. Each of the two frames includes one groove. The impeller is connected to the motor and is driven to rotate by the motor. The housing assembly houses the impeller and includes first and second housing parts. The first and second housing parts are engaged with each other by way of fastening. A protruding lip is provided on one of two end faces of the first housing part which is relatively adjacent to the motor. Another protruding lip is provided on one of two end faces of the second housing part which is relatively adjacent to the motor. The protruding lip and the other protruding lip are engaged with the grooves of the two frames.

What is claimed is: 
     
         1 . A fan comprising:
 a motor;   two frames coupled with an outer periphery of the motor and engaged with each other by way of fastening, wherein each of the two frames includes one groove;   an impeller connected to the motor and driven to rotate by the motor; and   a housing assembly housing the impeller and including a first housing part and a second housing part, wherein the first and second housing parts are engaged with each other by way of fastening, wherein a protruding lip is provided on one of two end faces of the first housing part which is relatively adjacent to the motor, wherein another protruding lip is provided on one of two end faces of the second housing part which is relatively adjacent to the motor, and wherein the protruding lip and the other protruding lip are engaged with the grooves of the two frames.   
     
     
         2 . The fan as claimed in  claim 1 , wherein the housing assembly further includes at least one fastening member, and wherein the first and second housing parts are fastened with each other through the at least one fastening member. 
     
     
         3 . The fan as claimed in  claim 2 , wherein at least one first coupling portion is provided on each of the two end faces of the first housing part, wherein at least one second coupling portion is provided on each of the two end faces of the second housing part, and wherein the at least one first coupling portion and the at least one second coupling portion are connected to each other by way of fastening through the at least one fastening member. 
     
     
         4 . The fan as claimed in  claim 3 , wherein each of the at least one first coupling portion includes a recess and each of at least one second coupling portion includes a tongue inserted into the recess. 
     
     
         5 . The fan as claimed in  claim 1 , wherein the two frames are fastened with each other through at least one fastening member. 
     
     
         6 . The fan as claimed in  claim 5 , wherein one of the two frames includes at least one first engagement portion, and wherein another of the two frames includes at least one second engagement portion engaged with the at least one first engagement portion by way of fastening through the at least one fastening member. 
     
     
         7 . The fan as claimed in  claim 6 , wherein each of the at least one first engagement portion includes a first concave portion and a first protruding portion, wherein each of the at least one second engagement portion includes a second concave portion and a second protruding portion, wherein the first protruding portion is engaged with the second concave portion, and wherein the second protruding portion is engaged with the first concave portion. 
     
     
         8 . The fan as claimed in  claim 1 , wherein one of the two frames includes a base, wherein another of the two frames includes another base, and wherein the base and the other base are connected to each other. 
     
     
         9 . The fan as claimed in  claim 8 , wherein the first housing part and the second housing part are coupled with each other to form a support, and wherein a bottom face of the support is in a same level as a level of the base and a level of the base. 
     
     
         10 . The fan as claimed in  claim 1 , further comprising a buffering member, wherein one of the two frames includes a receiving portion, wherein another of the two frames includes another receiving portion, and wherein the receiving portion and the other receiving portion are connected to each other to receive the buffering member. 
     
     
         11 . The fan as claimed in  claim 1 , further comprising another impeller and another housing assembly, wherein the other impeller is driven to rotate by the motor and is located at one side of the motor opposite to another side of the motor where the impeller is, wherein the other housing assembly houses the other impeller, wherein one of the two frames includes two grooves, and wherein another of the two frames includes another two grooves.
