Improved Water Pistol Assembly with Pulse Fire System

U.S. Patents 5,605,253, 5,865,344, and 6,123,229, among many others, describe known water pistol assemblies. The typical water pistol has a simulated gun body that serves as a water receptacle, a pumping mechanism for dispensing water, a trigger mechanism for triggering the pump, and a nozzle through which the water is forced. Such inventions are popular in the summer among kids. However, the prior disclosures do not make reference of a pulse fire water pistol system that reduces water usage and increases enjoyment.

Figure 1 discloses a schematic version of the dual chamber water pistol 100. Dual chamber water pistol 100 can be virtually any conventionally known water pistol or water dispensing device. Water pistol 100 has pulse fire element 200 that provides pulse fire capability to the water pistol. Dual chamber water pistol has two exit nozzles capable of firing two distinct streams of water.

Figure 2 shows an up close view of dual chamber pulse fire element 200. The key elements of dual chamber pulse fire element 200 are the rotary motor 230, rotary shaft 240, and two flow interrupters 250. Rotary motor 230 can be a battery-operated motor. Flow interrupter 250 has holes that match up with the end of the water pistol dispensing hose. As the motor rotates rotary shaft 240, the each flow interrupter intermittently opens and closes the end of water pistol dispensing hose, providing a dual chamber pulse fire effect in the water pistol. Mechanical linking elements 260 connect the rotary shaft 240 to each flow interrupter 250. The flow interrupters 250 can be positioned or oriented such that both are open and contiguous with the water pistol dispensing hose at the same time, providing dual pulses, or they can be oriented such that only one hole is open at a single time, providing alternating pulses.

This invention can be used with virtually any water pistol or water dispensing mechanism. This pulse fire element allows for reduced water usage and greater enjoyment of the device.
