A saving water tank of closestool

Abstract

An intermediate water-saving closestool water tank. A basin drain pipe is connected to the closestool water tank. Before the closestool is used, a time-delay valve ( 13 ) or a ping-pong valve is pressed so that tap water is supplemented when the water supply tank of the basin is not full. After the tap water is supplemented in the water tank and before the closestool is flushed, the ping-pong valve needs to be pressed again to prevent a ball float type water supplementary valve ( 14 ) from automatically supplementing tap water subsequently. The time-delay valve ( 13 ) does not need to be pressed again, and a flushing valve ( 17 ) is pressed normally when the closestool is flushed. Two flap valves are arranged at the bottom of the basin, one of the flap valves is directly connected to the drainage sewer, and the other one is communicated with the closestool water tank. The device achieves energy-saving and water-saving purposes.

1 . A saving water tank of closestool, its characteristic lies in, its water supply pipe firstly connects to a delay valve or a ping-pong valve or any other on-off valve each ( 13 ) can be controlled on said tank, then the water supply pipe connects to the water supply valve ( 14 ), namely the water supply must get through said valve ( 13 ) to reach said water supply valve ( 14 ). 
     
     
         2 . According to  claim 1  said saving water tank of closestool, its characteristic lies in, Only one turn-over valve is installed on the bottom of washbasin which drainpipe installed filters ( 12 ) to remove deposit of waste water connects to said saving water tank of closestool, or two turn-over valves at least are installed on the bottom of washbasin which one connects to said saving water tank of closestool and another connects to sewer to drain the waste water containing deposit. 
     
     
         3 . According to  claim 1  said saving water tank of closestool, its characteristic lies in, the water supply valve ( 14 ) of the float water supply valve set ( 19 ) installed upside down will close when its disc move upwards and open when its disc move downwards, and its drawing pole joins said disc to a float ( 15 ). 
     
     
         4 . A ping-pong valve installed in said saving water tank of closestool, its characteristic lies in, will open and close alternately in the process of pressing the top of said valve repeatedly;
 The ping-pong valve seat ( 24 ) is assembled under the upside of said valve body which forms the horizontal runner of the slide piece ( 23 ) and can be designed as one body;   A gap between the valve cross pole ( 28 ) and the bottom of said upside valve body composes a ring channel of water under which the valve disc ( 27 ) supported by the reset spring ( 26 ) can shut said ring channel assisted with water pressure when pressing said valve top repeatedly. Two on-off poles( 22 ) which can be replaced by anyone of those locating on the valve cross pole ( 28 ) with the end section of diamond or spindle or other shape with two spires insert into surface runner ( 41 ) of the slide piece ( 23 ). Said surface runner ( 41 ) with heart shape can force the on-off poles to stop at its two maximal extremum points leaning to one side which corresponds with the open or close position of the valve disc ( 27 ) alternately in the process of pressing the top of ping-pong valve repeatedly.   
     
     
         5 . According to  claim 4  said ping-pong valve installed in said saving water tank of closestool, its characteristic lies in, the diameter of the valve disc ( 27 ) with some holes or net for passing of water approaches the inner diameter of downside of said valve body, or several directional teeth ( 25 ) which equivalent diameter is just smaller than outer diameter of said ring channel locates on the valve disc, or several directional poles locate apeak on the valve cross pole or at the side of the valve disc, each method said above can force the valve cross pole only to move up-downwards. 
     
     
         6 . A ping-pong valve installed in said saving water tank of closestool, its characteristic lies in, after optimized said ping-pong valve cannot be pressed downwards in case of no water which can forbid water supply to possibly run out when water comes on after pause in water pipe. The slope piston ( 52 ) of hydraulic jack ( 50 ) locating in the valve body downside under the reset spring ( 26 ) will move downwards to permit the release spring ( 53 ) forcing the block staff ( 56 ) to back into said hydraulic jack so said block staff cannot block the valve cross pole forepart ( 54 ) under the valve disc moving down when water supply comes on. Said slope piston will move upwards under the force of pressure inductive spring ( 51 ) then said block staff will move out of said hydraulic jack to block said valve cross pole forepart to move downwards when there no water supply. A vent hole ( 55 ) can be made at the bottom of said hydraulic jack to release the air pressure within it;
 Some sealed air in the cylinder of said hydraulic jack can substitute for said pressure inductive spring;   Said slope piston together with said hydraulic jack can be designed to move or lay along horizontal direction.   
     
     
         7 . According to  claim 1  said saving water tank of closestool, its characteristic lies in, an optimized said saving water tank of closestool characterized as below can substitute for it:
 a flush button ( 68 ) on said water tank can be pressed only once to complete flushing toilet action which can press down flush saving energy spring ( 65 ) and water supply saving energy spring ( 67 ) at the same time. Said flush button designed as one integral body can be replaced by two linkage buttons where said water supply saving energy spring can be pressed down alone or along with the motion of being pressed down of said flush saving energy spring, or replaced by three linkage buttons in which said two saving energy spring can be pressed down separately or along with the motion of being pressed down of a middle button; 
 Said water supply saving energy spring ( 67 ) in the condition of being pressed will act on said delay valve ( 13 ) through a stick float ( 66 ) when said saving water tank is lack of water thereby opening said delay valve, but when said saving water tank is full of water said stick float cannot open the delay valve because of the buoyance met by stick float. A water supply block device ( 615 ) locates beside the underside of said stick float in which an active triangle slider ( 62 ) fixed on the surface of stick float will conjugate with passive triangle slider ( 64 ) fixed on water supply block-iron ( 60 ) and sliding in the block-iron sheath ( 63 ) with hollowed top slot so said stick float can move upwards and force said water supply block-iron to slide into said block-iron sheath then said delay valve will be released to shut water supply in the period of tank becoming full of any water, but when said stick float moves down and press said delay valve down to certain position forced by water supply block-iron spring ( 611 ) said water supply block-iron slides out said block-iron sheath to suppress said delay valve to being opened; 
 A flush block device ( 610 ) locates beside the nether end ( 613 ) of said flush saving energy spring ( 65 ). When said saving water tank have no water the float ( 15 ) will fall down, without drawing of a pulley set, will release the nether block-iron of said flush block device forced by its spring to force the nether stop-iron ( 612 ) blocking said flush saving energy spring going down so the flushing toilet butterfly valve cannot be opened, at the same time without drawing of another pulley set the saving energy block device ( 69 ) is in its release status in which the upper block-iron forced by its spring comes out to situate the upper stop-iron ( 614 ) in horizontal pose, while being pressed the upper end of said flush saving energy spring will get across said upper stop-iron ( 614 ) and be blocked under it, therefor said flush saving energy spring is being in saving energy pose; 
 At the state of saving energy pose and once said water tank being full of any water said float will float up and through a pulley set release said nether stop-iron ( 612 ) consequently release said flush saving energy spring to open the flushing toilet butterfly valve, almost simultaneously, said nether end ( 613 ) of said flush saving energy spring ( 65 ) through another pulley set will draw back said upper block-iron then release said upper stop-iron ( 614 ) where the upper end of said flush saving energy spring ( 65 ) is to get across and stop there, as well as supported by the flush reset spring ( 61 ) said flush saving energy spring is to stop above said nether stop-iron ( 612 ); 
 Said flush block device ( 610 ) and said saving energy block device ( 69 ) can be replaced separately by what similar to said water supply block device ( 615 ) in which one similar to said active triangle slider ( 62 ) should be fixed on said stick float ( 66 ) or another similar one or said float ( 15 ), and another similar to said active triangle slider should be fixed at the nether end of flush saving energy spring.
