Toilet buoy unit to control water flow
Kind Code:
A1


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.

Claims:
1. Toilet buoy unit to control water flow comprising one upper chain, one discal cover, one buoyant cup, one set of flash light circuit, one nonconducting stick, one conductive metal ring, one discal weight and one lower chain.

2. The said upper chain in claim 1 has one upper hook and one lower hook. The said upper hook hooks up a hole at the end of toilet lever.

3. The said discal cover in claim 1 is a cover that has one central hook-ring on the top and one central hook at the bottom Wherein the said central hook-ring is hooked up by the said lower hook of the said upper chain in claims 1 and 2.

4. The said buoyant cup in claim 1 is made of light materials and has a central hole to pass the said nonconducting stick and conductive metal ring in claim 1 and two built-in electric poles. Wherein the said built-in electric pole is installed by the side of the said central hole and its end exposes inside the said central hole as conductive electric brushes for conductivity. Without external weight the said buoy-cup floats in water and its buoyance keeps its upper portion approximate one and a half inches floating above the water level. The diameter of the said central hole is smaller than that of the said discal cover in claims 1 and 3. The said buoyant cup is approximate one and a half to two inches tall and in diameter.

5. The said one set of electric flash light circuit has one flash light bulb, one battery power source and one set of electric wire circuit. The wires of the said wire circuit connect to the said built-in electric poles in claim 4

6. The said nonconducting stick in claim 1 is approximate one and a half inches long and is made of nonconducting material. The said nonconducting stick has one top hook-ring, one threaded end and one bottom hook-ring. The said top hook-ring is hooked up by the said central hook of the said discal cover in claims 1, 3 and 4. The diameter of the said nonconducting stick is smaller than that of the said conductive metal ring in claim 1.

7. The said conductive metal ring in claims 1 and 6 is about a half inch long and encircles the middle portion of the said nonconductive stick in claims 1 and 6 for conductance between the said conductive electric brushes in claim 4. The size of the said conductive metal ring is little larger than the distance from one side of the said electric brush to the other side of electric brush in order to contact both side of electric brushes for conductance.

8. The said discal weight in claim 1 has a central threaded hole to be screwed into by the said threaded end of nonconducting stick in claims 1, 6 and 7 and is placed inside the said buoyant cup in claims 1 and 4. The said discal weight can submerge the said buoyant cup in claims 1 and 4 to a level approximate a half inch from its top.

9. The said lower chain in claims 1 has one superior hook and one inferior hook. The said superior hook hooks up the said bottom hook-ring of the said nonconducting stick in claims 1, 6, 7 and 8. The said inferior hook hooks up the hook-ring of toilet flapper tank ball. During the installation the length of the said lower chain should be adjusted just long enough to sink the said buoyant cup to a level approximate a half inch from its top.

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.

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.
