Electric fan structure

Abstract

The present invention provides an improved electric fan structure, in which an electric fan is structured from an air converging vent; a main body and a base. The air converging vent comprises a plurality of guide strips, which are used to concentrate the air at an upper portion of the main body, and the bevel angled guide strips guide the air draft into the main body. The air is made to form a powerful vortex by means of a pass through type wind wheel formed as an integrated body in conjunction with a drive device causing the wind wheel to rotate, after which an induced draft plate covering a periphery of the wind wheel sends the air to an air outlet, where the air is blow out, thereby achieving functionality to realize optimum air volume output, and, at the same time, reduce noise when the electric fan is rotating.

1 . An electric fan structure, comprising an air converging vent; a main body extends from the air converging vent, and a base extends from the main body, an air outlet is located at one side of the main body, and a heat dissipation vent is located at another side of the main body, a drive device is disposed within the main body; wherein the drive device is electrically connected to a wind wheel formed as an integrated body, and the wind wheel assumes a pass through form, thereby increasing joint compactness and reducing the difference in air volume input and air volume output while simultaneously reducing noise when the wind wheel is rotating. 
   
   
       2 . The electric fan structure according to  claim 1 , wherein the air converging vent comprises a plurality of guide strips, thereby enabling the electric fan to guide the inflow of air into the main body through the guide strips, and a powerful vortex is formed through rotation of the wind wheel, after which the air blow is blown out through the air outlet. 
   
   
       3 . The electric fan structure according to  claim 1 , wherein a wind wheel disc is disposed between the drive device and the wind wheel, and the drive device is electrically connected to the wind wheel disc; the wind wheel disc is further joined to the wind wheel, thereby enabling effective control of rotation of the wind wheel and outflow of air.

The electric fan structure according to  claim 1 , wherein a side edge of the main body further comprises a control interface, and the control interface is electrically connected to a circuit board; the amount of drive power of the drive device is controlled by means of the circuit board, which further controls quantity of air of the electric fan. 
   
   
       5 . The electric fan structure according to  claim 1 , wherein an induced draft plate further covers the exterior of the wind wheel, enabling air volume expelled when the wind wheel is operating to be guided to the air outlet by the induced draft plate, thereby enabling the electric fan to achieve optimum air output. 
   
   
       6 . The electric fan structure according to  claim 1 , wherein light emitting devices are further installed on the base, the light emitting devices provide illumination effectiveness, and at the same time increase aestheticism and uniqueness of the electric fan. 
   
   
       7 . The electric fan structure according to  claim 1 , wherein the electric fan is further installed on a vehicle, and, at the same time, aromatic compounds are disposed within the electric fan, thereby increasing multivariate use of the electric fan.
