Technical Field

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

Background

Liquid dispensing systems are well known in the art and are commonly used for cleaning and watering applications. Liquid dispensing systems, such as sprayers, are typically connected to a liquid supply tube to supply the liquid to be dispensed. The sprayer may be connected to the liquid supply tube in a known manner, such as by threads with a sealing mechanism. Typically, the sprayer and the liquid supply tube are designed to mate with each other for connection. Sprayers are usually provided with a nozzle, also called a spray nozzle, and an inlet. The inlet is connected to a liquid supply pipe, and the spray nozzle sprays the liquid. Further, the inlet of the nebulizer may have a predetermined length for maintaining the pressure of the water or liquid passing through the nebulizer. Typically, in use of the liquid dispensing system, a user holds the sprayer and positions the nozzle in an orientation that requires liquid to be dispensed for cleaning and/or watering applications. Thus, the range and application of the liquid dispensing system may be limited by the reach of the user.

Chinese patent CN201558777U (hereinafter patent No. 777) relates to an extended handle of a sprayer. The elongated handle includes reinforcing ribs. There is a linear groove around the end of the elongate handle. The linear groove is connected with the inner side of the connecting pipe joint in a linear groove mode and is positioned through a bolt. One side of the connecting pipe joint is connected with the water pipe connector. The fixing means is composed of a connecting plate, and a connecting band is provided at the other end. The upper part of the front end of the lengthened handle is provided with a gripping handle. The front end of the extension handle is connected with the connecting pipe and is provided with a step bolt. The connecting pipe is arranged in the lengthened handle and is positioned through the upper rod screw. The side end of the connecting pipe is provided with an elbow (elbow) and is connected with the 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 to a connecting tube. Although patent No. 777 provides a sprayer extension handle, the connecting tube and valve in the sprayer extension handle may not be connectable to the various sprayers and handles used in garden watering systems.

Accordingly, in view of the above, there is a need for an improved garden watering apparatus.

In one embodiment, the first end 124 of the body portion 126 of the adapter 106 is a solid end that is removably coupled to the opening 122 of the elongate member 102. The first end 124 is configured with a plurality of flat surfaces 128 and stepped portions 130 and detents 132. During connection of the adapter 106 with the elongated member 102, the first end 124 of the adapter 106 is inserted into the opening 122 of the elongated member 102. The knob 134 is disposed in the elongated member 102 configured to contact the plurality of flat surfaces 128 to connect and lock the adapter 106 with the elongated member 102. The knob 134 is threaded onto the elongated member 102. Rotation of the knob 134 in a predetermined direction connects and locks the first end 124 of the adapter 106 with the elongate member 102. The adapter 106 may be moved longitudinally to slightly adjust the height of the adapter 106 relative to the elongate member 102. Thus, the adapter 106 is configured to connect with any elongate member 102 having a different length.

The body portion 126 of the adapter 106 further includes a second end 136. The second end 136 is opposite the first end 124. The second end 136 of the body portion 126 is a hollow cylindrical portion and is provided with attachment means such as, but not limited to, threads 138 (shown in fig. 4).
