detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Fig. 3, the design comprises columnar water tank 1, upper hose 2, delivery port 5, downcomer 6, the sliding plug 3 of an approximate H-shaped is provided with in the inner chamber of water tank 1, sliding plug 3 is left by office, connecting rod 9 between two pieces of onesize circular sebens 7 on right side and two sebens forms, connecting rod is connected to the center of seben, the diameter of seben 7 is close to the size of water tank 1 lumenal cross-section diameter, effectively can cut off the water body in water tank by this, simultaneously because have connecting rod that left and right seben is connected to two ends thus increase sliding entire length of filling in, therefore sliding plug can not block other some retardation when water tank cavity horizontally slips, left and right seben 7 all processes gap and gap 8, the low gap 10 of arcuation on top, wherein gap 8 is a little more than low gap 10, low gap 10 again a little more than delivery port 5, as shown in Fig. 4, Fig. 2, Fig. 5, the volute springs 4 be close on the right side of sliding plug 3, sliding plug when not having the operation of upper and lower water in water tank cavity and the combination of spring are near the left and right end face of water tank cavity all the time, namely as shown in Figure 1 they occupy most spaces of water tank cavity jointly, and device volute spring is then taken less feature because it has by compression rear space.In concrete use, for Fig. 1, now can be understood as the firm device of water tank good, water waterborne to be added in water tank for preparing use, start indoor upper taps cold water and enter water tank 1 from upper hose 2, first current can be clogged in the little space of sliding plug 3 left end in water tank, water flow impact pressure in the gravitational pressure of water body and upper hose pipeline can force sliding plug to overcome the faint elastic force falling frictional force and spring and promote sliding plug to the right and move to right until the water tank right-hand member end of shape shown in Fig. 3, current direction covers gap 8 and enter between seben until the space, right side of sliding plug, water in water tank has been filled it up with releasing from delivery port 5 and downcomer 6 and has been presented at indoor, now close close taps stop add water, because the hydraulic pressure of sliding plug left and right sides is tending towards impartial, can move to left again after cold water filled it up with by water tank at the left effect downslide plug that becomes of the elastic force of spring and revert to the original position place of left end, as Fig. 1 shape, when preparing to release the hot water in water tank, also be enter water tank 1 in by cold water from upper hose 2 by starting indoor upper taps, in like manner, the water flow pressure in sliding plug left side promotes sliding plug and moves to right, sliding plug can squeeze first outer for the hot water on the right side of it and pass through delivery port, downcomer releasing, and the hot water of now releasing is exactly the hot water in water tank cavity, and it there is no infiltrates cold water, so water temperature is stable, as shown in Figure 2, when the hot water water yield needing to release is larger, continue to add water in water tank, as shown in Figure 3, because sliding plug has been shifted to the right to right stop, first the cold water added in inlet water tank can be flow to the water cavity between two sebens and be flowed out to water outlet overflow by low gap by the hot water being mixed with portion of cold water again at gap 8 place, the proportion of the hot water flowed out because of smaller so upper strata can be in first flows out, though the hot water water temperature now flowed out reduces a little but because there being the deadening effect of sliding plug still much higher than the water temperature of the water tank outflow not arranging sliding plug than the water temperature at initial stage, the water that such temperature decreases continues outflow until hot water outflow is finished the cold water only having in water tank and newly add, with finishing, taps is closed in pass, sliding plug is got back to again original position as in the previous and is re-used next time after cool water heating becomes hot water.The design is relative to the former design water tank arranged before sliding plug, due to the deadening impetus of cunning plug and the right seben owing to filling in from delivery port 5 to cunning, the low overfall 10 at left seben top place, the height of overfall 8 is stepped in what increase successively, being added overheated water body by solar energy in water tank is all being outflowed by delivery port and reverse outflow can not occur gradually from right to left substantially, the water temperature of hot water flowed out be not mixed into cold water substantially thus maintain higher water temperature range just finally time water temperature reduce, the situation that be mixed into hot water water body in more outwards releasing directly overall relative to the cold water of former design water tank, it is the improvement of a large performance and usefulness.
