Below be operating principle of the present utility model:

Water shutoff and drainage principle: when water enters in the water tank (6) and do not have draining sealing ring (18), because the effect of hydraulic pressure, on the upper surface of draining sealing ring (18), produce a downward pressure, rising along with height of water level, this pressure constantly increases, when not having overflow pipe floating drum (10), the water surface produces a buoyancy that makes progress, but this buoyancy is less than overflow pipe assembly part weight and the downward pressure sum of draining sealing ring (18), therefore, the overflow pipe assembly can not move, at this moment, the utility model is the water shutoff state; When be full of in the water tank water and overflow pipe (12) be raised by the effect of external force or by the rotation knob (5) make overflow pipe (12) when mentioning, water in the water tank (6) is by the drain hole outflow of water-drainage base seat (19), the upper and lower surface of draining sealing ring (18) this moment all is subjected to the effect of hydraulic pressure, its active force is close to zero, and the buoyancy that overflow pipe floating drum (10) produces is greater than the weight of overflow pipe assembly, the overflow pipe assembly can not fall, and this moment, the utility model was in hull-borne; Drawdown in water tank (6) is to a certain height, and when the buoyancy of overflow pipe floating drum (10) can't support the weight of overflow pipe assembly, the overflow pipe assembly fell and resets, and the utility model is in the water shutoff state again, finishes a water shutoff, draining circulation this moment.

Full drainage principle: when the knob that turns clockwise (5), the knob rotating shaft (2) that is fixed together by organic solvent with knob (5) drives knob lever (1) and draining slide fastener (15) motion, the commutation that moves through angle pulley (8) of draining slide fastener (15) is converted to the motion of vertical direction, thereby the overflow pipe (12) that is connected with draining slide fastener (15) is moved upward along the straight tube of swivel bearing frame (11), the overflow pipe assembly leaves water-drainage base seat (19), realizes the draining action.When drawdown during to certain altitude, the overflow pipe assembly resets, and this moment, displacement was the major part of water tank (6) water yield, shows that full draining action finishes.

Half drainage principle: when being rotated counterclockwise knob (5), the knob rotating shaft (2) that is fixed together by organic solvent with knob (5) drives knob lever (1) and draining slide fastener (14) motion, the commutation that moves through angle pulley (8) of draining slide fastener (14) is converted to the motion of vertical direction, thereby the half draining sleeve (9) that is connected with draining slide fastener (14) is moved upward along the straight tube of swivel bearing frame (11), half draining sleeve assembly then drives the overflow pipe assembly when rising and moves upward, at that time, sleeve limited block (16) is pressed on the overflow pipe assembly by the position-limiting action of swivel bearing frame (11) diagonal bar, because on the draining sealing ring (18), below stressed being close to zero, the buoyancy of overflow pipe floating drum (10) is greater than overflow pipe assembly and half draining sleeve assembly weight sum, and this two assembly all can't fall and leave water-drainage base seat (19).At this moment, the utility model is a hull-borne, when drawdown is extremely regulated the bottom surface of cup (13), the water of regulating cup (13) lining produces the effect of a downward power because can not drain off by a leak A who is positioned at adjusting cup (13) below in moment, this power is passed to the overflow pipe assembly by sleeve limited block (16), and this power and half draining sleeve assembly, overflow pipe assembly weight three sum is greater than the buoyancy of overflow pipe floating drum (10), therefore, half draining sleeve assembly and overflow pipe assembly fall to resetting, this moment, displacement was the part of water tank (6) water yield, be approximately half water, show that half draining action finishes.And half displacement also can be done upper and lower adjustment along the straight tube of swivel bearing frame (11) by regulating cup (13), thereby according to the degree of fouling of toilet, reduces or add more than half displacement.

Above-mentionedly why can finish full draining or half draining action respectively, be because by rotate knob (5) the lifting height difference when driving overflow pipe (12) or half draining sleeve (9) respectively and leaving water-drainage base seat (19), the height that the former rises is higher than the latter, and the displacement of the former action just is greater than the displacement of latter's action.

The utility model compact conformation, easy to use, can according to rinsing requirement the degree of fouling of toilet, discharge a part of water or whole water of water tank (6) lining respectively, and can regulate water supply volume, using water wisely can be widely used in the toilet water tank (6) and the supporting use of water intaking valve.
