摘要： A hand held household or hobby type spray gun is provided with a pistol grip housing having a transverse bore receiving a removable piston pump and nozzle assembly, suspending a removable container for the medium to be sprayed, and covered by a removable cap enclosing an electric motor for driving the piston of the pump. The pump and nozzle assembly is locked in the bore by a quarter turn rotation which seats a detent in a recess of the bore. The electric motor is energized from an external power source through a cord carried by the cap or from batteries which may be mounted in a chamber provided by the grip or handle portion of the housing. The housing may be a one-piece injection mold plastics material member, and the removable container for the media to be sprayed as well as the closure gap for the motor may also be injection mold plastic material members. The grip or handle portion of the housing span the rear side of the spray gun and has a front recess embracing the container. The pump portion of the housing overlies the handle portion and extends at right angles thereto with lateral or side grooves in its outer face to receive the fingers of the hand of an operator grasping the handle. A motor actuating button is mounted in one of the recesses. The assembled spray gun is a canister of rectangular shape with rounded corners preferably having a generally cylindrical front face with the pump nozzle projecting from the apex thereof while the electric cord projects from the rear face of the cover or cap. The components of the spray gun are easily disassembled to accommodate cleaning, replacement of worn parts and the like.
