ABSTRACT:
A hot air gun or blower of the type usable for blistering paint on a painted surface for easing the removal of paint thereof has a housing with internal brackets supporting and retaining a switch assembly, a circuit board, a motor having an impeller, a motor mount, a shroud surrounding the impeller, and a heating element. The internal brackets supporting these elements are configured so as to provide a number of air passages between the elements and the interior wall of the housing. In addition to drawing air through a rear portion of the gun, air is drawn through an annular opening in the front of the gun between the cover for the heating element and the housing. The air thus passes over the covered heating coil and is preheated before being blown by the impeller directly over the coil for primary heating. At least one wave-like flange is received between spaced interior brackets in the housing for providing a press fit of the components between the two housing halves, thus eliminating the need for mechanical fasteners for mounting the components of the gun.
