Fan assembly and air shield apparatus

Abstract

An air shield apparatus includes a bracket, a number of baffles, and a connecting member. The bracket includes two opposite side plates. Each baffle includes a blocking piece placed between the side plates of the bracket, and a shaft located at a first side of the blocking piece. The shafts are rotatably connected to the side plates of the bracket. The connecting member includes a connecting pole and a number of pivot portions pivotably connected to the baffles.

What is claimed is: 
     
         1 . An air shield apparatus, comprising:
 a bracket comprising two opposite side plates;   a plurality of baffles each comprising a blocking piece placed between the side plates of the bracket, and a shaft located at a first side of the blocking piece, wherein the shafts are rotatably connected to the side plates of the bracket; and   a connecting member comprising a connecting pole and a plurality of pivot portions pivotably connected to the baffles.   
     
     
         2 . The air shield apparatus of  claim 1 , wherein each pivot portions defines a pivot hole, each baffle further comprises a post, the posts of the baffles are inserted in the corresponding pivot holes. 
     
     
         3 . The air shield apparatus of  claim 2 , wherein a second side of each blocking piece opposite to the first side defines a cutout, the post protrudes from an inner surface of the cutout and parallel to a lengthwise direction of the shaft, the post and the blocking piece cooperatively bound a space communicating with the corresponding cutout, the pivot portions are received in the cutouts through the spaces. 
     
     
         4 . The air shield apparatus of  claim 1 , wherein the bracket further comprises a top plate and a bottom plate, the two opposite side plates, the top plate, and the bottom plate cooperatively bound an installing space, the baffles are received in the installing space, each of the side plates defines a plurality of pivot holes communicating with the installing space, two opposite ends of the shaft of each baffle are inserted in two corresponding pivot holes of the side plates. 
     
     
         5 . A fan assembly, comprising:
 a shell defining an air outlet;   a fan received in the shell and aligning with the air outlet; and   
       an air shield apparatus comprising a bracket mounted to the shell, a plurality of baffles pivotably mounted to the bracket to cover or uncover the air outlet, and a connecting member pivotably connected to the plurality of baffles; 
       wherein the bracket comprises two opposite side plates, each baffle comprises a blocking piece placed between the side plates of the bracket, and a shaft located at a first side of the blocking piece, the shaft of each baffle is rotatably connected to the side plates of the bracket, the connecting member comprises a connecting pole and a plurality of pivot portions pivotably connected to the baffles. 
     
     
         6 . The fan assembly of  claim 5 , wherein each pivot portions defines a pivot hole, each baffle further comprises a post, the posts of the baffles are inserted in the corresponding pivot holes. 
     
     
         7 . The fan assembly of  claim 6 , wherein the second side of each blocking piece opposite to the first side defines a cutout, the post protrudes from an inner surface of the cutout and parallel to a lengthwise direction of the shaft, the post and the blocking piece cooperatively bound a space communicating with the corresponding cutout, the pivot portions are received in the cutouts through the spaces. 
     
     
         8 . The fan assembly of  claim 5 , wherein the bracket further comprises a top plate and a bottom plate, the two opposite side plates, the top plate, and the bottom plate cooperatively bound an installing space, the baffles are received in the installing space, each of the side plates defines a plurality pairs of pivot holes communicating with the installing space, two opposite ends of the shaft of each baffle are inserted in the corresponding pivot holes of the side plates.
