Submersible battery operated water pump system

This application claims priority to U.S. Provisional Patent Application No. 61/329,578 filed Apr. 30, 2010.

The proposed submersible battery-operated water pump system applies to the decorative water fountain industry. The invention is a system designed to operate a water fountain by means of a cordless, water-safe submersible, rechargeable battery. Currently on the market are water fountains powered by traditional AC and DC electricity, each of which has limitations to functionality. Water fountains powered by conventional AC electricity require a power cord from the fountain to be plugged into an electrical wall outlet within close proximity, which limits accessibility and poses the risk of electrocution. Traditional DC powered fountains are cordless, however, they do not provide the voltage necessary for strong water circulation. In addition, the water pump in these models is not water submersible and will not operate if it becomes wet. The proposed invention solves these issues by combining cutting edge water pump and battery technology to comprise a water pump system that operates with enough voltage to circulate a high volume water flow, but has the advantage of cordless portability and safety.

The present invention provides a cordless submersible water pump system comprised of a water pump connected through waterproof connectors to a rechargeable battery for the purpose of recirculation of water. A brushless DC water pump provides optimal energy management for the specifically designed Lithium Ion battery to maintain a total energy-efficient system. The means for connecting power from the battery to the water pump is achieved through a waterproof connection comprised of a plug connector and receptacle connector. This invention incorporates the features of existing water pump and battery technology and applies them in a new context. This invention is intended to, but not limited to converting corded water fountains to an independently operational cordless unit.

Referring to the drawings, FIG. 1 illustrates the 1 water pump, the 2 auxiliary connector, the 3 auxiliary cap, the 4 plug connector, the 5 receptacle connector, and the 6 battery. FIG. 1A illustrates a close up view of the 4 plug connector and the 5 receptacle connector before connection. FIG. 2 illustrates the 8 outlet and the 7 suction cups. FIG. 3 illustrates the submersible battery operated water pump system in operation with the 22 flow coming from the 8 outlet of the 1 water pump with the 7 suction cups holding the 1 water pump at the bottom of the 20 reservoir of 21 water.

FIG. 4 Illustrates the 1 water pump with the 8 outlet, the 10 flow dial, the 7 suction cups. FIG. 5 illustrates the 6 battery coated in the 9 synthetic rubber. FIG. 6 is a view of the 6 battery being dipped into the 12 synthetic rubber for waterproofing.

The submersible battery operated water pump system is activated as such: The 1 water pump is placed in the 20 reservoir with the 7 suction cups secured to the bottom. The 4 plug connector is inserted into the 5 receptacle connector to comprise a waterproof circuit to the 6 battery to distribute electrical power to operate the 1 water pump. Once the 1 water pump and 6 battery are connected the 22 water will flow through the 8 outlet. The flow rate can be adjusted by the 10 flow dial.

While the present invention has been proposed with specific embodiments as outlined, it is implied to those skilled in the art that modifications or various changes may be made that fall within the scope of the invention and the context of the intended claims.
