1. A toy squirt gun for shooting a continuous stream of water, comprising:

  • (a) a structure means for containing water and air under high internal pressure, said structure means being configured to facilitate partially filling with water leaving an internal volume for compressed air, a water fill port means, a pressurization pump means, a trigger means, a flow control valve means, a battery-powered oscillator circuit means, a flow actuated sound generator means and a nozzle means;

    (b) said fill port means being attached to said structure means and including a removable cap corresponding to an aperture in said structure means, whereby said fill port means provides access for partially filling said squirt gun with water, the cap being resealable so as to not permit leakage when said squirt gun is operating under high internal pressure;

    (c) said pressurization pump means being operably coupled to said structure means, providing hand-held support for said squirt gun and operating to compress air into said structure means, said pressurization pump means including a movable member means for facilitating manual actuation thereof;

    (d) said nozzle means being coupled to said structure means, said flow control valve means being fluidly coupled via a passageway within said structure means to said nozzle means, said control valve controlling flow of pressurized water to said nozzle means;

    to shoot said squirt gun said trigger means being manually actuated to open said control valve means and thereby permit pressurized water flow through said nozzle means, said water flow exiting said nozzle means and thereby said squirt gun at high velocity;

    (e) said flow actuated sound generator means including a rotatable impeller means mounted integral and within said structure means and interposed between said control valve means and nozzle means and adapted to rotate when flowing water moves from said control valve means to said nozzle means, and also including vibration means mounted externally on said structure means and operably coupled to said impeller means for activation upon rotation of said impeller means;

    wherein said vibration means comprises a horn cylinder means, a horn piston means, a first reed vibrator means and a second reed vibrator means, said first and second reed vibrator means being attached to said cylinder means, said piston means being positioned inside said cylinder means, rotation of said impeller means causing said horn piston means to cycle back and forth inside said horn cylinder means and thereby alternatingly force air through said first and second vibrator means causing said first and second vibrator means to vibrate and produce pulsating sounds; and

    (f) said battery operated oscillator circuit means being attached to said structure means and including a switch means for controlling on and off states of said circuit means, said switch means being coupled to said trigger means to simultaneously switch said circuit means to an on state when said trigger means is actuated to shoot said squirt gun, said circuit means operating to produce pulsating sounds when switched to an on state.
