ABSTRACT:
There is disclosed a portable misting fan formed by upper and lower body portions which are joined together along a joint. The joint is improved by providing the lower body portion with a non-circular neck portion along its top end, and wherein the upper body portion includes two halves which terminate in lower body collar sections, intended to be joined together in overlying relationship relative to the neck portion. A rail and groove system is employed as between the upper first and second body portions, and the neck portion, so that the rails will slidingly engage the grooves in the neck portion rendering the joint resistant to rotation. The neck portion includes an aperture into which a sleeve is press fitted, the sleeve includes upper and lower lips, and the lower body collar sections include inwardly extending flanges which overlie and engage the upper and lower lips formed in the sleeve, thereby brace and secure the pump assembly within the device.
