Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application is related to and claims priority to U.S. Provisional Patent Application No. 62/397,691 filed Sep. 21, 2016, which is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.

TECHNICAL FIELD

The present invention relates generally to the field of pumps of existing art and more specifically relates to an inline fluid pump.

RELATED ART

A pump is a device for moving fluids through mechanical action. A variety of mechanical solutions for pumps exist, such as displacement pumps, direct lift pumps, and gravity pumps. All pumps function by converting energy into a mechanical action, such as rotary or reciprocating movements, in order to move the fluid. Applications vary from microscopic medical pumps, to agricultural fluid distribution, to large industrial pumping applications. Pumps may be used to pump drinking water from wells, filter bodies of water, aerate fluids, transfer fuels, and remove natural resources from the earth.

While the variety and versatility of pumps allow them to be used in many applications, they are usually specialized for a single purpose and may be difficult to adapt to other uses. Issues such as portability, power sourcing, and methods of interfacing with the fluid can result in such inflexibility. A suitable solution is desired.

U.S. Pat. No. 8,393,877 to Colin Metcalfe relates to a portable liquid pump. The described portable liquid pump includes a portable hand held controllable and directable liquid pumping device including a vortex pump head fitted to a first end of an elongate flexible drive shaft and a pump drive fitted to a second end of the flexible drive shaft in which the pump drive includes a substantially rigid elongate housing for a portion of the drive shaft and the elongate housing includes a first handle at or near the first end remote from the pump drive.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known pump art, the present disclosure provides a novel inline portable electric fluid pump. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a inline portable electric fluid pump.

An inline portable electric fluid pump is disclosed herein. The inline portable electric fluid pump includes a pump housing, a fluid-conveying cavity, a pump drive, an inlet hose, an outlet hose, a nozzle, a nozzle interface, an electric motor, and an electrical interface.

DETAILED DESCRIPTION

As discussed above, embodiments of the present disclosure relate to a pump and more particularly to an inline portable electric fluid pump as used to improve the displacing of a fluid.

Generally, the inline portable electric fluid pump provides users with a portable handheld pump system operated via a rechargeable battery. This allows users to displace liquid from a container without the need for hand pumping, syphoning, and the like. It includes interchangeable nozzles for various situational usages. It features an adjustable motor speed selection and optional automatic pumping when a nozzle is opened. The inline portable electric fluid pump offers a fast, easy, and convenient method for firefighters to battle fires, lawn and garden professionals to water their plants, and much more.

The inline portable electric fluid pump is an on-demand pressure system for various types of pumps. The device is comprised of a portable handheld pump system operated via rechargeable battery. A suction line and discharge line with a nozzle can be included. The system can be hooked onto any type of container capable of dispensing water, gasoline, hazardous chemicals, and other materials. The pump can be inserted into a container and then activated. This primes the pump to a set motor setting, and the pump turns off automatically until the nozzle is opened. Once open, the pump may start the transfer of liquid until the nozzle is once again closed. The process can be repeated to dispense as much liquid as required. The portable pump may be constructed using rubber, plastic, and other suitable materials. Exact size, measurement, construction, and design specifications may vary upon manufacturing.

Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4C, various views of a portable pump 100.
