Blower and impeller structure thereof

Abstract

A blower includes a driving device and an impeller structure having a hub, a connecting part, and a plurality of blades. The driving device connects to and drives the hub. The connecting part is disposed around the hub and has a plurality of apertures. The blades are disposed at the periphery of the connecting part.

1 . An impeller structure, comprising: 
 a hub;    a connecting part disposed around the hub and having a plurality of apertures; and    a plurality of blades disposed at the periphery of the connecting part.    
   
   
       2 . The impeller structure of  claim 1 , wherein the apertures are symmetrically or randomly arranged around the hub.  
   
   
       3 . The impeller structure of  claim 1 , wherein the apertures are rectangular, trapezoid, polygonal, circular, half-moon-shaped, sickle-shaped, sector-like, regular, or irregular.  
   
   
       4 . The impeller structure of  claim 1 , wherein the apertures comprise a plurality of first apertures disposed adjacent to the hub and a plurality of second apertures disposed adjacent to the blades, and the first apertures and the second apertures are alternately arranged.  
   
   
       5 . The impeller structure of  claim 1 , wherein an aperture-making process is applied on the connecting part to form the apertures.  
   
   
       6 . The impeller structure of  claim 1 , wherein the apertures and the connecting part are simultaneously formed.  
   
   
       7 . The impeller structure of  claim 1 , further comprising: 
 at least one filler, which is filled in at least one of the apertures or in/on the connecting part.    
   
   
       8 . The impeller structure of  claim 7 , wherein the filler is made of metal, plastic, glue, putty, carbon fiber, or the material of the impeller structure.  
   
   
       9 . The impeller structure of  claim 1 , wherein the number of the apertures is 6 to 15 or more.  
   
   
       10 . The impeller structure of  claim 1 , wherein the apertures have the same shape or difference shapes.  
   
   
       11 . The impeller structure of  claim 1 , wherein the apertures go through or not go through the connecting part.  
   
   
       12 . A fan, comprising: 
 an impeller structure, which comprises: 
 a hub,  
 a connecting part disposed around the hub and having a plurality of apertures, and  
 a plurality of blades disposed at the periphery of the connecting part, and  
   a driving device for driving the impeller structure to rotate.    
   
   
       13 . The fan of  claim 12 , wherein the fan is a centrifugal fan or a blower.  
   
   
       14 . The fan of  claim 12 , wherein the apertures are symmetrically or randomly arranged around the hub.  
   
   
       15 . The fan of  claim 12 , wherein the apertures are rectangular, trapezoid, polygonal, circular, half-moon-shaped, sickle-shaped, sector-like, regular, or irregular.  
   
   
       16 . The fan of  claim 12 , wherein an aperture-making process is applied on the connecting part to form the apertures.  
   
   
       17 . The fan of  claim 12 , wherein the apertures and the connecting part are simultaneously formed.  
   
   
       18 . The fan of  claim 12 , wherein the impeller structure further comprises: 
 at least one filler, which is filled in at least one of the apertures or in/on the connecting part, wherein the filler is made of metal, plastic, glue, putty, carbon fiber, or the material of the impeller structure.    
   
   
       19 . The blower of  claim 12 , wherein the number of the apertures is 6 to 15 or more.  
   
   
       20 . The blower of  claim 12 , wherein the apertures have the same shape or difference shapes.
