Abstract
A water gun (10) is provided having a pressure tank (19) in fluid communication with a coupler (20) adapted to be received upon a conventional water faucet, and a pump (42) for conveying additional air to the pressure tank. The flow of water from the water faucet draws ambient air which is compressed within the pressure tank to pressurize the water therein. The pressurized liquid is released through a nozzle (21) coupled to the pressure tank by actuation of a trigger (17).
Claims15
A toy water gun comprising:
- a pressure tank adapted to hold liquid and air;
- coupling means for coupling said pressure tank to a remote source of pressurized liquid so as to create a stream of liquid from the remote source to said pressure tank;
- mixing means in fluid communication with said pressure tank and said coupling means for drawing air and mixing the air with the stream of liquid from the remote source of pressurized liquid;
- conduit means for conveying liquid from said pressure tank to ambience;
- and
- control means for controlling the flow of liquid through said conduit means,
- whereby the passage of liquid through the mixing means draws air into the stream of liquid which is then forced into the pressure tank wherein the air within the pressure tank is compressed so as to pressurize the liquid within the pressure tank.
A toy water gun comprising:
- a receptor configured to be received upon an outlet for a source of pressurized water;
- a pressure tank adapted to hold water and air;
- conduit means extending between and in fluid communication with said receptor and said pressure tank;
- mixing means coupled to said conduit having an inlet in fluid communication with ambient air for mixing ambient air with the pressurized water passing through said conduit means from said receptor to said pressure tank;
- whereby the air mixed into the pressurized water is compressed within the pressure tank so as to exert a force upon the water within the pressure tank greater than ambient pressure.
A method of pressurizing air within a pressure tank of a toy water gun comprising the steps of:
- (a) coupling the pressure tank to a supply of pressurized water;
- (b) creating a stream of water from the supply of pressurized water to the pressure tank;
- (c) mixing air into the stream of water prior to entering the pressure tank;
- and
- (d) storing the water and air within the pressure tank in a manner so that the air therein pressurizes the water therein.
