According to the utility model discloses device of shaking head, drive shaft 104 intermeshing through with rotor 102 and driving piece 100, make driving piece 100 can directly drive rotor 102 and rotate, when rotor 102 rotates, because the guide rail on the rotor 102 and the one end joint of connecting rod 106, and the other end fixed connection of connecting rod 106 is on the body, make rotor 102 along self central axial displacement, again by rotor 102 and driving piece 100's meshing relation, make rotor 102 can drive driving piece 100 and swing, thereby realized the function that drives driving piece 100 and shake the head. The oscillating device is applied to the fan, so that the structure of the oscillating device in the prior art can be greatly simplified, and the oscillating stability of the fan is improved.

Specifically, referring to fig. 1 and fig. 2 in combination, the driving member 100 of the present embodiment may use a motor, etc., and the driving shaft 104 of the driving member 100 faces the side of the transmission assembly in the oscillating device. In order to ensure that the oscillating direction of the driving member 100 is in a horizontal plane, the driving shaft 104 of the driving member 100 rotates in the horizontal plane. Of course, when it is necessary to adjust the direction of the swinging head of the driver 100 in the vertical plane, the rotation direction of the driving shaft 104 of the driver 100 may be adjusted to rotate in the vertical plane.

The rotating body 102 in the transmission assembly is engaged with the driving shaft 104 in the driving member 100, wherein the rotating direction of the rotating body 102 and the rotating direction of the driving shaft 104 in the driving member 100 are perpendicular to each other in the same plane.

In this embodiment, the driving shaft 104 is a worm, and the end surface of the rotor 102 is provided with a worm wheel that meshes with the worm. The matching mode of the worm gear and the worm has the advantages of simple structure, stable transmission and high precision.

Of course, in other embodiments, a bevel gear may be disposed at the end of the driving shaft 104, and similarly, a bevel gear engaged with the aforementioned bevel gear may be disposed on the rotating body 102 to realize the engagement transmission between the driving shaft 104 and the rotating body 102.
