DETAILED DESCRIPTION OF THE INVENTION

The present invention is directed to a device that is installed on the in-line chlorinator reservoir and can be used to detect the amount of chemical remaining in a chlorinator reservoir used to disinfect pools.
The chlorinator indicator 500 comprises the means to visually determine the level of chemical remaining in the reservoir and means to attach the chlorinator indicator 500 to the chemical reservoir. FIG. 1 shows one example of the preferred embodiment of the present invention prior to installing in with in-line chlorinating system. As shown in FIG. 1, the chlorinator indicator 500 comprises a cylindrical pipe 100 with a cap 110 on its top end 101 and a coupler 120 on its bottom end 102. It also comprises a rod 200, which extends out from the bottom end 102 of the cylindrical pipe 100 and has a diameter smaller than the cylindrical pipe 100.
The chlorinator indicator 500 comprises the means to visually determine the level of the chemical remaining in the reservoir and the means to connect the chlorinator indicator to the chemical reservoir. In one embodiment of the present invention, the means to visually determine the level of the chemical remaining in the reservoir comprises hollow, clear UV resistant cylindrical pipe 100 that encloses rod 200. In an alternative embodiment, the means to visually determine the level of the chemical remaining in the reservoir comprises a substantially hollow, substantially clear cylindrical pipe 100. Thus, while the cylindrical pipe of the present invention may in some embodiments be absolutely hollow and absolutely clear, it is understood that in other embodiments, the cylindrical pipe 100 of the present invention does not necessarily have to be absolutely hollow or absolutely clear.
FIG. 2 shows a cross sectional side view of one of the embodiments of the present invention. As shown in FIG. 2, the chlorinator indicator 500 comprises a clear, UV resistant cylindrical pipe (sight tube) 100. This pipe 100 has a top end 101 and a bottom end 102. The top end 101 is covered by a cap 110. There is a coupler 120 placed on the bottom end 102 of the pipe. This pipe encloses a rod 200 that has a diameter less than that of the pipe 100. The rod 200 comprises a head 210, which is also known as indicator stop and a shaft 220. The head 210 of the rod 200 stays in the cylindrical pipe 100 at all times as the rod 200 slides inside the cylindrical pipe 1.00. One example of the manner in which the rod 200 with the head 210 and shaft 220 is shown in FIGS. 3A-3C. FIG. 3A shows the schematic view of head 2.10 of the rod 200. FIG. 3B depicts the cross-sectional view of the head 210 with center 211. FIG. 3C shows a side-view of the head 210 attached to the rod 200. The head 210 is drilled in the center 211 and attached to the diameter of the shaft 220 as shown in FIG. 3C. The shaft 220 is then pressed and glued into the hole so that the head 210 and shaft 220 are permanently bonded together and slide inside the cylindrical pipe 100. The head 210 of the rod is sized so that there is a small amount of clearance between it and the cylindrical pipe 100 and the head 210 is substantially larger than the opening at the bottom 102 of the cylindrical pipe 100 where the shaft 220 exits the cylindrical pipe 100. The rod 200 is constructed in such a manner to allow it to slide up and down the cylindrical pipe 100.
The bottom end 225 of the shaft 220 contacts the chemical inside the reservoir when the chlorinator indicator 500 is installed on top of the chlorinator 600. FIG. 4 shows the chlorinator indicator 500 installed on top of the chlorinator 600. The reservoir cap 300 replaces the original in-line chlorinator cap and has a threaded hole in the center to which coupler 120 screws into in order to secure the chlorinator indicator 500 in place. The head 210 aligns the rod 200 in the pipe and prevents the shaft 220 from moving in the lateral direction. The head 210 of the rod 200 guides the shaft 220 of the rod through the opening in coupler 120 and reservoir cap 300. The head 210 and shaft 220 of the rod 200 moves freely within the cylindrical pipe 100.
As gravity pulls the head 210 and shaft 220 of the rod 200 down, the bottom end 225 of the shaft 220 makes contact with the contents of the reservoir, thereby indicating the level of the chemical inside the reservoir. This level can be viewed through the cylindrical pipe 100, which is made of clear, polyvinyl chloride and UV resistant material. As the level inside the reservoir drops to zero, the head 210 of the rod 200 contacts coupler 120 to prevent the shaft 220 from falling out of the pipe 100. The cap 110 of the cylindrical pipe 100 is also used as a stop so that the head 210 and shaft 220 of rod 200 are contained inside the cylindrical pipe 100, thus, making it a sealed indicating system.
The chlorinator indicator 500 described in the present invention allows the user to visually determine the level of disinfectant remaining in the reservoir without having to remove the cap or cover of the reservoir. The chlorinator indicator 500 comprises a cylindrical pipe 100, which encloses a rod 200. The pipe 100, the coupler 120, and the rod 200 may have different sizes and colors. Regardless of the size of the cylindrical pipe 100 and rod 200, the rod 200 has a diameter that is less than the cylindrical pipe 100 so that the rod 200 can move freely within the cylindrical pipe 100. The diameter of the cylindrical pipe 100 can preferably range from ½ inch to 1.0 inch, with ¾ inch being the preferred size. The diameter of the rod 200 can preferably range from ¼ inch to ¾ inch with ½ inch being the preferred size. One example of the size and various embodiments of the present invention is shown in FIG. 2. It is contemplated herein that the cylindrical pipe 100, the cap 110 and the coupler 120 may be made of materials including but not limited to polyvinyl chloride, acrylic and other plastic material. The cylindrical pipe 100 may also be made of UV-resistant material including but not limited to polyvinyl chloride, acrylic or other plastic material to prevent the pipe from discoloring over time. The length of the cylindrical pipe 100 and the rod 200 depends upon the size of the chemical reservoir. The length of the conventional chlorine reservoirs are 12 inches and 24 inches. The coupler 120 may preferably be a standard ¾ inch polyvinyl chloride pipe to ½ inch National Pipe Thread (NPT) threaded pipe. While a preferred shape of the reservoir cap 300 is shown in FIG. 2, it to be understood that the reservoir cap 300 can be manufactured to have any suitable shape, size or dimensions as needed or desired. Thus, as shown in FIG. 4, the reservoir cap 300 operates to attach securely over the chlorinator 300 or any chemical reservoir that stores chemicals for disinfecting water venues.
As used herein, the term “aperture” used to describe the threaded aperture of cap 300 is understood in the art to mean an opening in the cap, where such an opening includes and is not limited to a hole, a slit, a crack, or a gap through which rod 200 can pass.
As used herein, the term “coupler” refers to a device or adaptor that can be used to join two or more components.
As used herein, the term “cap” used to describe cap 300 in the present invention replaces the original in-line chlorinator reservoir cap.
As used herein, the term “install” used herein refers to a preferred mechanism for attaching, affixing or supporting the device of the present invention on top of the chlorinator or chemical reservoir.
The foregoing descriptions of the embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed. The exemplary embodiments were chosen and described in order to best explain the principles of the present invention and its practical application, to thereby enable others skilled in the art to best utilize the present invention.
