TECHNICAL FIELD

The present invention relates to a fluid dispensing system, and more particularly to an adapter for the fluid dispensing system.

BACKGROUND

Fluid dispensing systems are well known in the art and are generally used for cleaning and watering applications. Fluid dispensing systems such as sprayers are generally connected with a fluid supply tube to supply fluid to be dispensed. The sprayers may be connected to the fluid supply tube by a known means like threads with sealing mechanisms. Typically, the sprayer and the fluid supply tube are designed to match one another for coupling. The sprayer is generally provided with a nozzle, also known as a spraying nozzle, and an inlet. The inlet is connected to the fluid supply tube, and the spraying nozzle sprays the fluid. Further, the inlet of the sprayer may have a predefined length for maintaining the pressure of the water or fluid passing through the sprayer. Typically, while utilising the fluid dispensing systems, a user holds the sprayer and positions the spraying nozzle in a direction where fluid dispensing is desired for cleaning and/or watering applications. As a result, reach and application of the fluid dispensing system may be limited by the reach of the user.

The Chinese Patent CN201558777U (hereafter referred as the Patent 777) relates to a Sprayer lengthened handle. The lengthening handle includes a reinforcing rib. A straight groove is present around the end of the lengthening handle. The straight groove is connected with the connecting pipe nipple with straight groove at the inner side, and it is located by the bolt. One side of the connecting pipe nipple is connected with the water pipe connector. The fixing device is composed of the connecting plate and the connecting belt is set at the other end. The upper part of the front end of the lengthening handle is equipped with a grab handle. The front end of the lengthening handle is connected with the coupling tube and equipped with a step bolt. The coupling tube is installed in the lengthening handle and is located by the step bolt. The side end of the coupling tube has an elbow and is connected with a water pipe.

The water pipe is connected with the water pipe connector. One end of the valve has a spray beam connector and the other end of the valve is connected with the coupling tube. The water pipe is connected with the water pipe connector. One end of the valve has a spray beam connector and the other end of the valve is connected with the coupling tube. Though the Patent 777 provides the sprayer lengthened handle, the coupling tube and the valve in the sprayer lengthened handle may not be coupleable with all sorts of sprayers and handles used in the garden watering systems.

Therefore, in light of the foregoing, there is a need for an improvement in garden watering devices.
