Abstract
A fan assembly that can be used as a cooling fan or an air circulator. The fan assembly can provide the cooling and air circulation functions simultaneously or separately. The intensity of the cooling and/or air circulation can be individually controlled and directed. The fan assembly includes a base unit, a mounting frame rotatably coupled to the base unit, and a plurality of blower housings, each enclosing a fan and coupled to the mounting frame. The mounting frame is rotatable about an axis parallel to the support plane of the base. At least one of the blower housings is rotatably mounted to the mounting frame. The position of the blower housings can be adjusted through the manipulation of a positioning handle that is coupled to the rotatable blower housing.
