Patent ID: 10060437

Abstract:
The present invention discloses a multiple shaking-head structure for a fan, comprising a front part of the fan, a shaking-head upper cover, a synchronous motor, a gear stand and a fixed frame, wherein the front part of the fan consists of a motor front cover, a motor and a motor rear cover; a first elastic clamp which has a first dentation structure is positioned on the motor rear cover; first springs and a first ball tack are positioned in the shaking-head upper cover, wherein the first ball tack is matched with the first dentation structure; the synchronous motor is positioned on a synchronous motor support, and a driving gear is fixed on the synchronous motor; a circle of annular gear is positioned in a disc above the gear stand, and the driving gear is engaged with the annular gear of the gear stand; a second elastic clamp is positioned below the disc of the gear stand and has a second dentation structure; and a second spring and a second ball tack are positioned on the side surface of the fixed frame, wherein the second ball tack is matched with the second dentation structure. The present invention integrates the function of adjusting by 90 degrees up and down, the function of large-angle head-shaking and the function of adjusting by 90 degrees left and right, so that the fan can achieve all-directional rotation and all-directional air-out.
