Fan apparatus

Abstract

A fan apparatus has a frame, a motor and at least one fan blade part. The frame has a through chamber where the motor and the fan blade assembly are configured. The fan blade assembly has a stationary blade and a moving blade. The stationary blade is fixed inside the chamber to go around the motor and has multiple first radial blade parts. The moving blade is coupled to a shaft of the motor and has multiple second radial blade parts. When each first blade part is corresponding to the corresponding second blade part, a first included angle is formed between each first blade part and the corresponding second blade part. Therefore, a pair of the stationary blade and the moving blade enhances the wind pressure of the fan apparatus.

1 . A fan apparatus comprising:
 a frame having a through chamber, an inlet opening formed in a front of the through chamber and an outlet opening formed in a back of the through chamber;   a motor mounted inside the through chamber and has a body and a shaft protruding from the body; and   at least one fan blade assembly configured inside the through chamber and comprising:
 a stationary blade fixed inside the through chamber and being around an outside of the body of the motor, wherein the stationary blade has a ring and multiple first blade parts that are radially extending from an outside of the ring according to a first slant curve direction; and 
 a moving blade coupled to the shaft along a same axle center as the stationary blade, wherein the moving blade has a seat and multiple second blade parts that are radially extending from an outside of the seat according to a second slant curve direction, wherein the first slant curve direction is opposite to the second slant curve direction; 
   wherein when each first blade part is correspond to the corresponding second blade part, a first included angle is formed between each first blade part of the stationary blade and the corresponding second blade part of the moving blade.   
   
   
       2 . The fan apparatus as claimed in  claim 1 , wherein a second included angle formed between each second blade part of the moving blade and an axle center of the moving blade is between 45 and 65 degree. 
   
   
       3 . The fan apparatus as claimed in  claim 1 , wherein the first included angle is between 85 and 95 degree. 
   
   
       4 . The fan apparatus as claimed in  claim 2 , wherein the first included angle is between 85 and 95 degree.
