Two Control-levers of toilet water flush system
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.
Regular toilet water flush system has only one control-lever. Therefore it uses the same amount of water to flush liquid human waste (urine) and solid human waste (feces). It wastes a large amount of water to flush urine. A person urinates several times a day and only defecates once a day. The present invented two control-levers of toilet water flush system provides one control-lever to flush small amount of water for urine and another control-lever to flush a larger amount of water for feces. Therefore the present invented two control-levers of toilet water flush system can save a large amount of water to relieve the shortage of water supply in big cities in the United States.
THE BRIEF DESCRIPTION OF THE INVENTIONThe present invented two control-levers of toilet water flush system provides a simple device to replace the existent single control lever of toilet water flush system. One can simply remove the old existing single control-lever of toilet water flush system and installs the present invented two control-levers of toilet water flush system to save a large amount of water to relieve the shortage of water in big cities in the United States. The cost to install the present invented two control-levers of toilet water flush system can be recovered in one month.
Referring now in detail to the drawings numeral 10 of
Claims
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.
