A diaphragm actuated toy water gun is provided which includes a housing having a handle with a trigger as well as a barrel with a water ejection nozzle located thereon. A water supply tank is connected to the main housing which can be filled with water. A pump is located on the housing for pumping water from the supply tank to at least one diaphragm chamber located on the housing. The diaphragm chamber is formed between a fixed wall and a flexible diaphragm, which can be deflected and expanded from its neutral position into a diaphragm housing. A release valve C the diaphragm assembly. Actuation of the release valve allows a stream of water to be ejected from the diaphragm water gun.

1. A diaphragm water gun, comprising: a housing; a supply tank connected to the housing; a diaphragm assembly connected to the housing, including a generally planar diaphragm located between a cover and a diaphragm housing, said diaphragm housing having an open end, said diaphragm being secured at the open end such that in a relaxed position said generally planar diaphragm extends across the open end and remains generally outside said diaphragm housing, a diaphragm chamber being formed between the cover and the diaphragm; a pump for drawing water from the supply tank and forcing the water into the diaphragm chamber so that said diaphragm expands into said diaphragm housing; a release conduit in fluid communication between the diaphragm chamber and a release valve; and an actuator connected to the release valve for moving the release valve from a first state, in which the valve is closed, to a second state, in which the valve is open to discharge water from the water gun. 2. The diaphragm water gun of claim 1, further comprising a check valve located between the diaphragm chamber and the pump. 3. The diaphragm water gun of claim 1, further comprising a second diaphragm assembly connected to the housing, including a second diaphragm located between a second cover and a second diaphragm housing, with a second diaphragm chamber being located between the second cover and the second diaphragm, the pump being arranged to draw water from the supply tank and force the water into both of the diaphragm chambers. 4. The diaphragm water gun of claim 1, wherein the diaphragm includes an enlarged peripheral rim, and at least one of the cover and the diaphragm housing include a complementary shaped groove to receive the peripheral rim. 5. The diaphragm water gun of claim 4, wherein each of the cover and the diaphragm housing include a complementary shaped groove to receive the peripheral rim. 6. The diaphragm water gun of claim 1, further comprising an over-pressure release valve in fluid communication with the diaphragm chamber. 7. The diaphragm water gun of claim 1, wherein the release valve is a disk valve that is rotated from a first, closed position to a second, open position about an axis of rotation. 8. The diaphragm water gun of claim 1, wherein the cover is generally flat. 9. The diaphragm water gun of claim 1, wherein the diaphragm housing includes a generally hemispherical end. 10. The diaphragm water gun of claim 9, wherein the hemispherical end is connected to a cylindrical section that extends away from the cover. 11. The diaphragm water gun of claim 10, wherein the cylindrical section comprises a tube that is connected to a separate end piece. 12. The diaphragm water gun of claim 1, wherein the cover and the diaphragm housing are removably connected together. 13. The diaphragm water gun of claim 1, wherein the actuator comprises a trigger located on a handle extending from the housing. 14. The diaphragm water gun of claim 1, further comprising a nozzle located at an end of the release conduit.
