Technical Field

[0001] The utility model relates to the field of floor fans, in particular to a shaking head regulating device for floor fans. Background Art

[0002] Floor fans used in daily life are generally equipped with a shaking device to increase the blowing area of ​​the floor fan. The shaking devices of common floor fans are currently composed of a gear reduction mechanism and a corresponding control mechanism of a crank rocker mechanism. The crank of the crank rocker mechanism converts the rotational motion transmitted from the gear reduction mechanism into the reciprocating swing of the rocker, thereby realizing the shaking motion of the machine head. However, since the length of the crank is fixed and the swing angle of the rocker is also determined by the specific structural dimensions of the crank mechanism, the floor fan can generally only reciprocate within a fixed angle range, and its shaking angle cannot be fine-tuned, which causes many inconveniences in daily use.

[0003] The utility model aims to solve the technical problems existing in the prior art, and for this purpose, provides a shaking head regulating device for a floor fan. Utility Model Content
