ABSTRACT:
A compact portable misting fan includes a novel and attractive housing which makes extremely efficient use of space, encased fan blades which are mounted between front and rear baffles, a liquid reservoir with an atomizer, conveniently located mist and fan controls, and an easily accessible battery compartment. The housing has a substantially flat profile with a substantially cylindrical upper section in which the fan is mounted and a substantially rectilinear lower section in which the reservoir and batteries are contained. The fan on/off switch is located on a lower portion of the cylindrical upper section and the misting button is located on an upper portion of the rectilinear lower section and on a side opposite to the fan switch. It is easily held in the user's hand so that the fan and the mister can be operated separately by thumb or index finger. A small hole is provided in the housing for the outlet of the atomizer. The outlet is preferably angled upward so that mist is sprayed into the path of air from the fan.
