Portable dc cooling fan with simulated oscillation

Abstract

The invention provides a portable DC cooling fan that performs the dual function of a cooling fan and a sleep aid by generating air movement and white noise useful for inducing sleep. The portable device includes a DC axial fan that blows air in one direction and is under the control of an electrical control system that receives power through an AC/DC adapter. The electrical control system includes one or more user interface switches through which a user can select fan speed and optionally, set the fan on oscillation mode, and thereby simulating airflow and the sounds of a standard oscillating fan without undergoing rotation. The portable DC cooling fan of the invention includes a housing having a plurality of openings on its front and rear surfaces that enable maximum air flow through the device. The invention also provides an article of manufacturer comprising an AC/DC adapter packaged with a portable DC cooling fan of the invention.
