Description

A kind of automatic flushing cistern with time-delay valve

The utility model relates to a kind of automatic flushing cistern, particularly relates to a kind of automatic flushing cistern of the flushing latrine excrement groove with time-delay valve.

The book number of being published in December, 1981 by the chief editor of Taiyuan engineering college is that 15040.4154 titles are loaded with the automatic siphon wc flushing cistern for " indoor water-supply drainage works ".This water tank all is a high level cistern, does not need the people to control, and water outlet relies on and flows into water yield automatism, utilizes siphon principle to carry out fixed time interval flushing excrement groove.The weak point of this automatic siphon wc flushing cistern be not the possessor nobody go into the lavatory it all self-timing discharge water at interval and wash just groove, cause the significant wastage of water resource.

The purpose of this utility model provides a kind of automatic flushing cistern that overcomes the band time-delay valve of above-mentioned technological deficiency.

The purpose of this utility model is achieved through the following technical solutions.It comprises casing, syphon, cleaning hose, upper hose and water supply valve, on the pipeline of the back of water supply valve, be in series with sliding spool, be connected to the throttling box behind the sliding spool, on the throttling box, comprise two delivery ports at least, wherein the water outlet of a delivery port flows into casing, the water of another delivery port flows into container, sliding spool relies on container to order about it because of the displacement of the difference formation of the weight that has or not water generates and moves back and forth and open, close, container need satisfy center of gravity under pin joint when anhydrous state, when the container amount of being filled with water greater than 4/5 volume the time its center of gravity than pin joint height, and formed tilting moment is the frictional force that is enough to overcome axis of rotation, because pin joint and symmetrical profile are at a distance of being Y, the container left side is heavy, can only be to counterclockwise changeing, lean against on the strong point, be in a kind of static balance state, put control stick on container, the pulling control stick makes container clockwise rotate pouring, outwell water receptacle and reset, lean against again and prepare dress water on the lever strong point according to the automatic revolution of the position of centre of gravity of anhydrous state.

The quick water storage of realization container can be adorned a upper container under throat bushing, this upper container satisfies when being unkitted water under jointed shaft, its mouthful up, the end down, when upper container during at the water that is equipped with 4/5, then on jointed shaft, the tilting moment of its generation can overcome the frictional force of rotation upper container to center of gravity, and its function is that the water of low discharge is stored, be poured in the container quantitative water is disposable by certain hour, utilize the power of the gravity of water as valve-off.

Realize that the quick water storage of container can also another way realize promptly in throttling box bottom, a drain plug being arranged directly over the container, be linked with back-moving spring above the drain plug, below by another spring handle it with the container connection.

For realizing that sliding spool relies on container to order about the sliding spool unlatching, close because of the displacement that the difference of the weight that has or not water generates forms, container is hinged on the long arm end of crank levers, container is abutted against on the strong point by self center of gravity effect, container and crank levers can rotate around balance pivot with forbidding toward each other, and crank levers is subjected to the pulling force that spring makes progress all the time.

Good effect of the present utility model is to have avoided existing automatic flushing cistern nobody goes into the wasting phenomenon of lavatory bath, and water saving saves money and reduces blowdown, and is simple in structure, uses reliable, easy to maintenance.

Further illustrate the utility model below in conjunction with accompanying drawing.

Fig. 1 positive cross-sectional schematic of the present utility model.

Fig. 2 analyses and observe local figure for A-A sectional view, the B-B of Fig. 1

The utility model is to draw at the automatic rainbow that has casing 18 syphons 17 cleaning hoses 16 to be combined into to have mixed time-delay valve on the water tank, and tap water forms pressure F behind opening valve 1 ₂Push sliding spool 2 (supposition container 13 this moment is not adorned water) open, water flows directly in the throttling box 4, is flowed out by delivery port 3 to flow in the casing 18, rises to the top of syphon 17 when water level, produce siphon in the courage, water backs down epithelium and enters cleaning hose 16 and remove the flushing sanitation utensil, and when the water in the casing 18 were bordering on emptying, epithelium was sucked back to the origin-location, it is suitable for reading to press cleaning hose 16, flushing promptly stops, and casing stores water again, for flushing is next time prepared.When there are flowing out, delivery port 3 have a low discharge water to flow out from throat bushing 5, flow in the container 19, when in the container 19 dress water reached its volume 4/5 the time, be hinged on the center of gravity of the container 19 on the rotatable shaft n-n, be higher than a n-n, its tilting moment is increasing, when tilting moment fully when hindering the frictional force that axle rotates, container 19 just begins turning pouring together with balancing weight 20, and whole water of dress are poured container 13 in the container 19, forms gravity F ₁, container 13 is hinged on and abuts against on the crank levers 11 on the strong point 9, and they are forbidden around balance pivot 12 rotations toward each other and elongate spring 10, by the galianconism end l of crank levers ₂Remove to push sliding spool 2 and close water inlet, after water inlet is closed, whole water tank stops flushing, because the pouring of tumbling of container 19 be based upon the water yield account for its volume more than 4/5 for prerequisite, the increase of the water yield needs the time, by the decision of the aperture of throat bushing 5, thus just successful control the purpose of time-delay pass water.Need flush the toilet if any the people, only need pull flush handle 8 control sticks 6 just around fulcrum 14 rotations, promote container 13 around axle m-m upset by pin 7, behind the upset pouring, under the effect of balancing weight 15, reset, prepare for adorn water next time, because container 13 anhydrous rear crank levers 11 are hauled rising by spring 10, sliding spool 2 has not had the active force of lever, and it is pushed open by tap water, water inlet is opened, and just begins the pass water of next time delaying time.

The utility model also has another kind of mode:

Container 19 does not allow the water that throat bushing 5 flows out directly enter in the container 13 exactly, after the water yield of its volume 4/5 is housed when container 13, it elongates spring 10 to bottom offset by the crank levers long arm end, at this moment curved bar lever short arm end pushes away spool 2 near water inlet, sliding spool is in a kind of critical condition, the tap water flow of inflow is fallen sharply, but water inlet is not closed fully.We are provided with drain plug 21 in order to avoid this state, when container 13 has obvious displacement, pulling spring 22 in the process that continues displacement, the drain plug 21 of leaving behind compresses springs 23, drain plug is moved down all to be flowed into the water of containing in the throttling box 4 in the container 13, make container 13 that the water of enough weight arranged, be pressed in and make sliding spool surmount critical condition on the crank levers, rapidly water inlet is closed fully.Other action is identical with first kind of mode.
