The storage battery 300 is charged through the charging interface and supplies power to the fan body 100. Because the storage battery 300 is heavy, it can serve as a counterweight structure. By being disposed near the base 220, the center of gravity can be lowered, allowing the floor fan to stand stably. This allows the base 220 to be smaller and eliminates the need for a counterweight, thereby reducing the manufacturing cost of the base 220. The structure of the support assembly 200 allows the floor fan to be used wirelessly and also enables it to stand stably.

[0030] Specifically, the fan body 100 has a conventional fan structure, which may have an oscillation mechanism and a tilting adjustment mechanism. The base 220 is used to support the ground, and the bracket 210 can extend along the height direction to support the fan body 100.
