Abstract

The present invention relates to an electric oscillating fan which can be used for simulating people's hands to swing fans. The appearance of the present invention is in a shape of a maid who wears a skirt and whose two hands hold a fan to stand. A mechanical structure of the present invention is mainly formed by that blades are inserted into an inserting seat, and the inserting seat is orderly and mechanically connected with a double-arm structure, a pulling mechanism, a rotating mechanism and a power mechanism. When a motor rotates, after a speed is reduced by a multi-stage belt wheel, a pull rod is driven to be pulled up and down, and then, a shoulder shaft is driven by a swinging rod to rotate back and forth; an upper arm swings by rotation of the shoulder shaft, a front arm is pulled by the pull rod to move together, and then, the blades which are installed in the inserting seat swing up and down to achieve the purpose of simulating people's hands to swing the fan. The electric oscillating fan is especially suitable for old people and children to relieve summer-heat and enjoy the cool in summer.
