Airflow generating structure and the apparatus thereof

Abstract

An airflow generating structure and the apparatus thereof includes a hub, a holding section extended outwards from one end of the hub, and a plurality of spoilers located on the periphery of the holding section in the axial direction that are spaced from one another. Each of the spoilers has two curved surfaces and an outer edge inclined outwards so that the area that all the tips of the spoilers enclose is larger than that of the holding section. Air is sucked in through one end of the hub remote from the holding section and flows towards the other end, and is discharged through the periphery of the holding section.

       2 . The airflow generating structure of  claim 1 , wherein each of the spoilers includes a convex surface and a concave surface.  
   
   
       3 . The airflow generating structure of  claim 1 , wherein each of the spoilers includes: 
 a root fastened to the holding section;    a tip remote from the holding section;    an inner edge close to the hub; and    an outer edge remote from the hub.    
   
   
       4 . The airflow generating structure of  claim 3 , wherein the outer edge of the spoiler directs outwards such that there is an inclined angle between the outer edge and the center axis of the hub.  
   
   
       5 . The airflow generating structure of  claim 3 , wherein the inner edge of the spoiler directs outwards such that there is an inclined angle between the inner edge and the center axis of the hub.  
   
   
       6 . The airflow generating structure of  claim 3 , wherein all the tips of the spoilers are coupled together by a stabilization ring.  
   
   
       7 . The airflow generating structure of  claim 1 , wherein there is a round angle at the juncture of the holding section and the hub.  
   
   
       8 . The airflow generating structure of  claim 1 , wherein the holding section includes a plurality of air vents located on the periphery thereof and arranged in an alternate manner relative to the spoilers.  
   
   
       9 . The airflow generating structure of  claim 1 , wherein there is a plurality of blades round the hub.  
   
   
       10 . The airflow generating structure of  claim 1 , wherein the holding section includes a plurality of openings on the area close to and round the hub.  
   
   
       11 . An airflow generating apparatus comprising: 
 a hub having a holding section extended from one end thereof;    a plurality of spoilers in a curved shape having one ends located on the periphery of the holding section and spaced from one another, and the other ends enclosing an area greater than that of the holding section; and    a motor for driving and rotating the hub.    
   
   
       12 . The airflow generating apparatus of  claim 11 , wherein each of the spoilers includes a convex surface and a concave surface.  
   
   
       13 . The airflow generating apparatus of  claim 11 , wherein each of the spoilers includes: 
 a root fastened to the holding section;    a tip remote from the holding section;    an inner edge close to the hub; and    an outer edge remote from the hub.    
   
   
       14 . The airflow generating apparatus of  claim 13 , wherein the outer edge of the spoiler directs outwards such that there is an inclined angle between the outer edge and the center axis of the hub.  
   
   
       15 . The airflow generating apparatus of  claim 13 , wherein the inner edge of the spoiler directs outwards such that there is an inclined angle between the outer edge and the center axis of the hub.  
   
   
       16 . The airflow generating apparatus of  claim 11 , wherein there is a round angle at the juncture of the holding section and the hub.  
   
   
       17 . The airflow generating apparatus of  claim 11 , wherein all the tips of spoilers are coupled together by a stabilization ring.  
   
   
       18 . The airflow generating apparatus of  claim 11 , wherein the holding section includes a plurality of air vents located on the periphery thereof and arranged in an alternate manner relative to the spoilers.
