Air circulator with vein control system
The present invention is related in general to air circulators, and in particular, to an air circulator with a vein control system to direct and adjust airflow patterns. According to an exemplary embodiment, the present invention provides adjustable, vertical veins that are attached to the outlet of a tower fan. According to a preferred embodiment, the veins are pivotally mounted in such a way that by turning a knob, the veins can either be directed into a focused air-flow pattern or adjusted to a divergent air-flow pattern, or at any setting in between.
