[0002] The main structure of an air circulation fan includes a drive motor, a turbo fan, a guide grille and a cylindrical shell. Unlike ordinary fans, air circulation fans can blow wind in a spiral shape along a certain direction. As the fan blades stir, a spiral columnar wind is eventually formed. The wind blown out by an air circulation fan can reach a longer distance and has better directionality.

[0003] For example, Chinese patent CN214891592U discloses a desktop circulation fan, which includes: a bottom plate, a first shaking head module, a second shaking head module, a base, a switch seat, a switch, a knob, a pitch spring assembly, a connecting screw, a rear net, a fan blade and a front net.
