ABSTRACT:
A hand held thermal electric fogging device is disclosed comprising a housing having a barrel-like connector provided thereon which is adapted to receive the valve means of an aerosol container containing the insecticide/oil solution. A plunger is movably mounted on the connector and is movable from a normal inoperative position to an operative position to open the valve means on the aerosol container so that the contents of the container are supplied to the discharge outlet of the connector. A tubular heat shield or manifold is connected to the housing and extends therefrom and has a coiled conduit positioned therein. The inlet end of the coiled conduit is connected to the outlet end of the connector so that the insecticide/oil solution is supplied to the interior of the conduit. A spray nozzle is provided on the discharge end of the conduit. An electrical heating means is positioned in the central area of the coil for heating the solution in the coiled conduit. A normally closed electrical switch means is provided on the housing for controlling the heating means. A lever is pivotally mounted on the housing and is selectively movable from a normal inoperative position to a first position wherein it closes the switch means to energize the heating means. The lever is also movable from the first position to a second position wherein the plunger in the connector is moved to its operative position so that the contents of the aerosol container are supplied to the coiled conduit which has been previously heated by the electrical heating means.
