Toilet buoy unit to control water flow

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.

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.
