Water spray gun

A water spray gun, comprising a gun body, the gun body comprising:

• a) an inner part, the inner part comprising a water channel;
• b) an outer part, the outer part comprising a handle;
• c) an upper part, the upper part comprising a spray bar, a water spray plate, a lock button, and a pull rod comprising a plug;
• and
• d) a lower part, the lower part comprising a water stop plug disposed at an distal end thereof, a water stop plate, a water stop spring, a first sealing ring for stopping water, and a second sealing ring for introducing water;
• wherein
• the water channel is disposed in the inner part of the gun body;
• the handle is movably mounted on the outer part of the gun body via a pin;
• when the handle is pressed down, the pull rod is pulled backward and the water stop plug moves downwardly under the force of the plug and drives the second sealing ring for introducing water to move outward to allow the water spray gun to stay at an open state;
• the water enters the gun body and is sprayed out via the spray bar and the water spray plate;
• the handle is pressed by the lock button to allow water to spray continuously;
• and
• when the handle is released, the pull rod is reset under a spring force and the water stop plug is reset under the force of the water stop spring, the first sealing ring for stopping water is driven to move forward, the water is sealed outside the gun body, and the water spray gun is at a closed state for keeping the water outside;
• when the water spray gun is closed, the plug cooperates with the water stop plug of the distal end to allow the water stop plate and the first sealing ring for stopping water to seal the water at the distal end for keeping the water out of the gun body thereby preventing the gun body from becoming stuck or rupturing.
