Abstract

Toilet buoy unit to control water flow is a device to control water flow to let only small amount of water draining into toilet to flush human liquid waste. A flash light bulb is provided to tell us small amount of water being drained. People defecate once a day and urinate several times a day. If we use toilet buoy unit to guide us to drain small amount of water to flush liquid human waste we can save a large amount of water to relieve the shortage of water supply in big cities in the United Status.

Description

THE BACKGROUND OF THE INVENTION

It requires only small amount of water to flush urine in toilet. The existing toilet flushing system flushes same large amount of water to flush urine as it does to flush feces. We urinate several times a day and only defecated once a day. We waste a large amount of water to flush urine daily. If we use a smaller amount of water to flush urine we can save a large amount of water to relieve the shortage of water supply in big citied in the United States.

THE BRIEF DESCRIPTION OF THE INVENTION

The present invented toilet buoy unit to control water flow is a simple device to guide us to use small amount of water to flush urine. It provides a flash light bulb. When the toilet push-handlebar is pushed downward to a certain level to drain certain small amount of water the flash light bulb is turn on. After small amount of water is drained for two to three seconds to flush urine user releases push-handlebar to shut off water. If we push push-handlebar downward too much the flash light bulb will turn off to tell us large amount of water is flushing and we have to release push handlebar a little bit to let flash light bulb lighted again to flush small amount of water.

Lower chain 40 has one superior hook 41 and one inferior hook 42. Superior hook 41 hooks up bottom hook-ring 35 of nonconducting stick 30. Numeral 43 of FIGS. 3, 4, 5 and 6 is toilet flapper tank ball. Toilet flapper tank ball 43 has one front hook-ring 44 and one rear hook-ring 45. Inferior hook 42 of lower chain 40 hooks up front hook-ring 44 of toilet flapper tank ball 43 as illustrated in FIGS. 3, 4, 5 and 6. Numeral 46 of FIGS. 3, 4, 5 and 6 is a tubular support in toilet water tank. Tubular support 46 has one hook 47 at each side.

When toilet flushing system is in closure status numeral 54 of FIG. 3 is the distance from toilet water level 20 to the front hook-ring 44 of toilet flapper tank ball 43. The first step to install the toilet buoy unit to control water flow 10 is to let water fill up toilet water tank. The second step is to measure the distance 54 from front hook-ring 44 to water level 20. The third step is to adjust the length of lower chain 40 to make the distance from mark line 48 of buoyant cup 18 to inferior hook 42 of lower chain 40 equal to the distance 54. The fourth step is to hook up front hook-ring 44 with inferior hook 42 of lower chain 40. The last step is to adjust the length of upper chain 11 to make upper chain 11 near a straight line after upper hook 12 of upper chain 11 hooking up hole 52 of toilet lever 50. The complete installation of toilet buoy unit 10 is illustrated in FIG. 3. When user pushes downward handlebar 51 to lift conductive metal ring 32 upward approximate one and a half to two inches high to contact the electric brush 28 to turn on flash light bulb 26 the front hook-ring 44 of toilet flapper tank ball 43 is elevated approximate one and a half to two inches to open the opening 55 of toilet water tank drainpipe 56 to drain small amount of water to flush liquid human waste as illustrated in FIG. 5. If user pushes handlebar 51 further downward to lift the conducting metal ring 32 higher than electric brush 28 flash light bulb will turn off to tell us large amount of water being draining through opening 55 of toilet water tank drainpipe 56 to flush solid human waste as illustrated in FIG. 6.
