ABSTRACT:
A swiveling electric fan comprising a truncated sphere-shaped housing which encloses a vane member, and a base having a concave or convex spheric top surface with the same diameter as that of the housing, the housing being connected with the base in a swiveling manner, an upper end of the supporting disk being secured to the housing while a lower end thereof extending into the base to connect with and abut against a rotary guiding disk of a swiveling mechanism in a swiveling manner, so that by means of rotating the guiding disk, a shaft section of the supporting disk is rotated in a circular hole of the top surface of the base, the circular hole being larger than the shaft section in diameter, whereby the vane member is made to swivel through an elliptical trace.
