Self-contained cleaning system for motor vehicles

A self contained washing system comprising a storage tank containing cleaning fluid, a pump driven by a direct current electric motor, both disposed within said storage tank, an external power cord, a hose, and a pistol shaped sprayer head, wherein:

• a compartment for optional batteries is provided within said storage tank;
• said pistol shaped sprayer head has an elongate upper portion, a pistol grip handle disposed below and to the rear of said upper portion, a trigger control piece disposed below said upper portion and to the upper, front section of said handle, and a nozzle selector with a plurality of differently shaped nozzles, rotatably secured to the front of said upper portion;
• a valve with a valve inlet, a valve outlet, and a valve gate is disposed within said sprayer head, said valve being continuously adjustable from an off state to a state of maximum flow, said valve gate is connected to and controlled by said control piece;
• said pump has a pump inlet and a pump outlet, said pump inlet communicating with the interior of said storage tank containing said cleaning fluid, said pump outlet being attached to a first end of said hose;
• an external inlet disposed on the exterior of said sprayer head communicates with said valve inlet and a second end of said hose is attached thereon, allowing said cleaning fluid to flow from said pump to said valve;
• an on/off electrical switch is disposed within said sprayer head and is turned on by rearward motion of said control piece;
• a first electtical wire and a second electrical wire, extending from said storage tank, are connected to a respective first terminal and second terminal of said electrical switch;
• a locking means enables said control piece to be releasably fixed at more than one pre-determined positions;
• said nozzle selector can be rotated to selectively align a said nozzle with said valve outlet and releasably fixed in place by a detent means;
• a magnet is disposed at the lower base of said handle;
• said external power cord can be connected with the electrical system of a motor vehicle to draw current therefrom, to power said motor, in place of said batteries in said battery compartment;
• whereby, depressing said control piece to the rear opens said valve and turns on said switch, starting said motor driving said pump and sending said cleaning fluid to said sprayer head, to emit from a said nozzle thereon;
• with said sprayer head releasably secured to a magnetically attracting surface by the action of said magnet in said handle, said control piece can be releasably fixed in position with said locking means to enable hands free operation of said self contained washing system, with a selected rate of flow issuing forth from said sprayer head.
