Abstract

A water gun and a watering container using an electrically operated peristaltic pump for pumping water through a nozzle located at the end of a tube connecting a reservoir with an outlet opening. The pump is electrically controlled by a trigger mechanism in a handle of the gun or container. The gun also includes a rotating light arrangement indicating that the gun is in use.

Claims

1. A pump operated spray assembly comprising a housing defining an outlet opening, a water reservoir in said housing, a tube leading from said reservoir to said outlet opening, a peristaltic pump for pumping water in said tube through said outlet opening which pump consists of a pump wheel having three rotatably mounted rollers secured thereto, a motor assembly including a motor and a gear drive including a first output shaft for rotating said pump wheel and said rollers to sequentially compress said tube to pump water out of said outlet opening, a power supply for said motor, and a trigger-operated circuit for activating said power supply to control the motor assembly to squirt water out the outlet opening in said housing.

2. A pump operated spray assembly as set forth in claim 1 comprising a water gun having a small decorative hemisphere extending out of an opening defined by an upper portion of said housing and the gear drive includes a second output shaft for rotating said hemisphere and a light emitting diode controlled by said circuit and located adjacent said hemisphere to provide a flashing light within said hemisphere when said gun is operated.

3. A pump operated spray assembly as set forth in claim 1 comprising a watering container including a main body portion, a cover having an opening and a cap therefore, said container defining a sealed-off section in the bottom portion thereof, the sealed-off section includes the peristaltic pump, the motor assembly and the power supply for said motor, the tube leading from the bottom portion of the watering container extending through said sealed-off section where it engages the peristaltic pump and then connects to the outlet opening.

4. A watering container as set forth in claim 3 in which there is an adjustable nozzle secured in place in said nozzle opening.

5. A watering container as set forth in claim 3 in which the container further includes a handle portion and the trigger operated circuit includes a trigger located in said handle portion for activating said power supply.
