ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a sprayer device, and more particularly to a sprayer device having an adjustable handle and having a water tight seal.
2. Description of the Prior Art
Various kinds of typical sprayer devices, such as the sprayer guns, sprayer heads, sprayer nozzles include a handle having a port for coupling to the water supply with a hose or the like. U.S. Pat. No. 5,690,312 to Yang discloses one of the typical sprayer devices. The handles of the typical sprayer devices include an integral one-piece configuration and may not be adjusted to different lengths. For adjusting to different lengths, the other handles of different lengths may be selectively secured to the sprayer devices. However, the frequent engagement and disengagement of the various handles to the sprayer devices may damage the water tight seal between the sprayer devices and the handles.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional sprayer devices.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a sprayer device including an adjustable handle and a water tight seal configuration.
In accordance with one aspect of the invention, there is provided a sprayer device comprising a sprayer member having a tube extended therefrom, the tube including a free end, a hose including a first end coupled to the free end of the tube and including a second end for coupling to a water reservoir, a pipe slidably engaged on the hose and including a first end slidably engaged on the free end of the tube, and a control ferrule engaged on the first end of the pipe for forcing the pipe to engage with the tube and to adjustably secure the pipe to the tube. The pipe may be easily moved and adjusted relative to the tube without affecting the water tight seal between the tube and the hose.
The pipe includes a barrel provided on the first end thereof, the barrel includes an outer thread provided thereon, the control ferrule is threaded with the outer thread of the barrel. The control ferrule includes an inclined inner peripheral surface formed therein for engaging with the barrel and for forcing the barrel to engage with the tube.
The pipe includes a second end, sprayer device further includes at least one conduit having a first end slidably engaged on the second end of the pipe, and a second control ferrule engaged on the first end of the conduit for forcing the conduit to engage with the pipe and to adjustably secure the conduit to the pipe.
The conduit includes a barrel provided on the first end thereof, the barrel includes an outer thread provided thereon, the second control ferrule is threaded with the outer thread of the barrel. The second control ferrule includes an inclined inner peripheral surface formed therein for engaging with the barrel and for forcing the barrel to engage with the pipe.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
