Fan diversion sturcture

Abstract

The present invention is to offer a fan diversion structure which is adapted to be disposed on a fan, and the fan diversion structure comprises at least one deflector and at least one connecting part. The deflector, which is adapted to be disposed across front of an air outlet of the fan, is disposed on one side next to a center of the fan and without overlapping the center of the fan, wherein the deflector extends outwardly so as to deflect an airflow to the side direction of the fan. The connecting part is adapted for connecting the deflector to the fan. Thereby the airflow from the fan not only converges in the axial direction, but also moderately extends to the side of the fan so as to increase the blowing angle and enhance convection efficiency around the fan.

1 . A fan diversion structure, which is adapted to be disposed on a fan, comprising:
 at least one deflector, adapted to be disposed across front of an air outlet of the fan, the deflector being disposed on one side next to a center of the fan and without overlapping the center, the deflector extending outwardly so as to deflect an airflow to the side thereof;   at least one connecting part, connecting the deflector to the fan.   
     
     
         2 . The fan diversion structure of  claim 1 , wherein the deflector has a curved surface, and the curved surface deflects the airflow outwards from the fan. 
     
     
         3 . The fan diversion structure of  claim 1 , wherein when the fan is an upright fan, the connecting part has two fasten components, the fasten components are respectively connected to two sides of the deflector, and the fasten components are adapted to be fastened on a net of the upright fan. 
     
     
         4 . The fan diversion structure of  claim 1 , wherein when the fan is a ceiling fan, the connecting part is a hollow annular board corresponding to a circular structure of the ceiling fan, the deflector further comprises two joint poles extending from the connecting part, the joint poles are respectively connected to two sides of the deflector and near to the center of the fan. 
     
     
         5 . The fan diversion structure of  claim 4 , wherein a hollow portion is defined between an inner margin of the deflector and the joint poles, the connecting part further comprises at least one supporting pole located between the joint poles, the supporting pole is connected to the inner margin of the deflector, and the supporting pole is close to the center of the fan. 
     
     
         6 . The fan diversion structure of  claim 4 , wherein the deflector is sectorial. 
     
     
         7 . The fan diversion structure of  claim 1 , wherein the quantity of deflectors is two, and each deflector is disposed symmetrically to two sides of the center of the fan.
