Two Control-levers of toilet water flush system

Abstract

Two control-levers of toilet water flush system provides two control-levers to control the amount of flush water. User presses downward one control-lever to flush small amount of water enough to flush liquid human waste and then releases it to shut off water. User presses downward another control-lever to flush a large amount of water to flush solid human waste. One person urinates a couple of time a day and only defecate once a day. If we use only small amount of water to flush urine then we can save a large amount of water to relieve the shortage of water supply in big cities in the United States.

1 . Two control-levers of toilet water flush system comprising one upper lever unit, one lower lever unit, one pivot block unit, one upper chain, one lower chain, one toilet flapper tank ball and two thumb screws. 
   
   
       2 . The said upper lever unit in  claim 1  consists of a handle, a pivot and a lever. Wherein the said handle connects to the said pivot to form L-shaped handle. Wherein the said lever has a larger hole at approximate half an inch from one end and a smaller hole near the other end. Wherein the said lever is fastened to the said pivot at the said larger hole of one end by one of the said two thumb screws in  claim 1  and is hooked by the said upper chain in  claim 1  at other end. 
   
   
       3 . The said lower lever unit in  claim 1  consists of a handle, a pivot and a lever. Wherein the said handle connects to the said pivot to form L-shaped handle. Wherein the said lever has a larger hole near one end and a smaller hole near the other end. Wherein the said lever is fastened to the said pivot at the said larger hole at one end by one of the said two thumb screws in  claim 1  and is hooked by the said upper chain in  claim 1  on top and the said lower chain in  claim 1  at the bottom. The said L-shaped handle is designed to restrict the said L-shaped handle of the said upper lever unit in  claim 2  to elevate the said toilet flapper tank ball to a height of only approximate one half to two inches enough to drain smaller amount of water into toilet to flush urine. 
   
   
       4 . The said pivot block unit in  claim 1  is a square block that has one upper inner canal and one lower outer canal and consists of one smaller front square pivot block and one larger back pivot block. Wherein the said upper inner canal admits the said pivot of L-shaped handle of upper lever unit in  claim 2 . Wherein the said lower outer canal admits the said pivot of L-shaped handle of lower lever unit in  claim 3 . Wherein the said small front square pivot block inserts into a square hole, that is used to install regular toilet lever unit, at the left upper corner of toilet water tank. Wherein the said larger back pivot block has one upper outer knot and one upper inner knot above the level of the said upper inner canal to restrict the range of movement of the said upper lever in  claims 1  and  2  and one lower inner knot below the level of the said lower pivot canal to restrict the downward movement of the said lower lever in  claims 1  and  3 . The location of the said upper inner canal and the said lower outer canal is also designed to let the said handle of L-shaped handle of lower lever unit in  claim 3  limit the downward movement of the said handle of L-shaped handle of upper lever unit in  claim 2 , and to enable upper lever unit to elevate the said toilet flapper ball in  claims 1  and  3  only to a range of approximate a half to two inches high enough to drain water into toilet to flush urine. 
   
   
       5 . The said upper chain in  claims 1  and  2  hooks on the said lever of upper lever unit in  claim 1  and  2  and the said lever of lower lever unit in  claim 1  and  3 . 
   
   
       6 . The said lower chain in  claims 1  and  3  hooks on the said lever of lower lever unit in  claims 1  and  3  at top and the said toilet flapper tank ball in  claim 1  at bottom. 
   
   
       7 . The toilet flapper tank ball in  claim 1  is a regular toilet flapper tank ball that is used to close toilet drainage opening at the bottom to shut off water or to be lifted to open toilet drainage opening to drain water. 
   
   
       8 . The said two thumb screws in  claim 1  are regular thumb screws that are used to fastened the said lever of upper lever unit in  claim 2  to the said L-shaped handle in  claim 2  and the said lever of the lever of lower lever unit in  claims 3  to the said L-shaped handles in  claims 3 .
