Water spray gun

A water spray gun comprising,

• a body, said body having a water inlet passage, a water outlet passage, a water chamber in communication between said water inlet passage and said water outlet passage;
• a water control valve mounted in said water chamber, said water control valve comprising a spherical valve block, said spherical valve block having a peripheral notch;
• a control lever pivoted to said body and biasable to rotate said water control valve between an open position where said peripheral notch of said spherical valve block is in water communication between said water inlet passage and said water outlet passage and a close position where said spherical valve block blocks said water outlet passage from said water inlet passage;
• a nozzle head connected to said water outlet passage, said nozzle head having a sliding slot cut through the periphery thereof;
• a spray pattern dial mounted in said nozzle head, said spray pattern dial comprising a first spray pattern plate fixedly mounted inside said nozzle head, said first spray pattern plate having a plurality of water jet nozzles disposed in water communication with said water outlet passage and a pivot rod perpendicularly extending from a front side thereof, a second spray pattern plate fixedly fastened to said nozzle head in front of said first spray pattern plate, said second spray pattern plate having a plurality of water jet holes and a center mounting hole coupled to said pivot rod of said first spray pattern plate, and an adjustment plate set in between said first spray pattern plate and said second spray pattern plate and rotatable relative to said first spray pattern plate and said second spray pattern plate to selectively control communication between the water jet holes of said first spray pattern plate and the water jet holes of said second spray pattern plate and to further control the spray pattern of water, said adjustment plate having a center pivot hole coupled to said pivot rod of said first spray pattern plate, a plurality of water jet holes alternatively set into communication between the water jet holes of said first spray pattern plate and the water jet holes of said second spray pattern plate, and a finger rod extending from the periphery thereof to the outside of said nozzle head through said sliding slot of said nozzle head for operation;
• and
• a spray cap covered on said nozzle head over said spray pattern dial, said spray cap having a plurality of water jet holes respectively disposed in communication with the water jet holes of said second spray pattern plate.
