No draining valve, watertight chamber pot flushing water device
Technical field: the utility model belongs to the application technology of siphon principle in toilet flush, is specifically related to a kind of watertight novel flushing mechanism of valveless.
Background technology: known numerous chamber pot flushing water mechanism partly forms by water intaking valve and discharging valve two, and the water inlet aperture of water intaking valve is all done very for a short time, utilizes ball float to add lever again and compresses water inlet, therefore can seal rare generation seepy question reliably.But discharging valve is just different, its bore is big, close initial the time, only be again to utilize some deadweight of rubber valve plate itself to be pressed on the dewatering outlet to seal, its thrust is little, and potted line is long again, therefore very easily produces seepy question, when especially rubber valve plate has distortion or circuitous valve port that some foreign matter is arranged slightly, will leak in a large number, cause waste, meet the social enviroment protection needs so produce a kind of flushing mechanism of antileaking.
Summary of the invention: the utility model is the novel flushing mechanism in the various tank for excrement pan, prior art is partly still adopted in the water inlet of its whole device, its innovation all is embodied in and discharges water partly, and it mainly is made up of rough undulation pipe, E shape threeway drainage tube, bath seat pipe and button etc.The rough undulation pipe is circle, makes with whippy rubber, be circle in the middle of the E shape threeway drainage tube, be the narrow few space that adapts in the water tank, both wings are then made oblateness, are used plastic blow molding, the lower end of rough undulation pipe tightly is enclosed within the suitable for reading of bath seat pipe, the upper end tightly is enclosed within on the central round mouth of E shape threeway drainage tube, and the water level in the water tank is controlled at the place suitable for reading of rough undulation pipe by existing water intaking valve.When button is pressed, rough undulation pipe pressurized promptly shortens, E shape threeway drainage tube promptly begins submerged, water promptly flows into the rough undulation pipe, rushes at water closet through bath seat pipe again by the both wings of E shape threeway drainage tube, produce flushing action, if let go this moment, the rough undulation pipe promptly can resilience raise, get back to more than the water level, and bath is promptly ended.Make the complete submerged of E shape threeway drainage tube if press the button, promptly can form siphonage this moment, makes the water in the water tank continue to flow into water closet, and the water level in water tank is lower than the water inlet of E shape threeway drainage tube both wings, cause air to enter and destroy till the siphonage, bath just comes to an end.Therefore two grades of flushing functions of size are arranged, if water level is too high in the water tank, water also can flow into water closet from E shape threeway drainage tube, therefore needn't establish bleed off pipe in addition.This water-drainage mechanism has been got rid of valve block, it is a kind of water-drainage mechanism of novel valveless, therefore can infuse the end eradicates because of discharging valve poor quality or the valve block seepy question that reason caused such as be not closed completely, its structure is compared with existing various jettison gears and is also wanted much simple, its component is few, not fragile, and water-saving result is preferably arranged.
Description of drawings: Fig. 1 is the utility model organigram.
Fig. 2 faces upward diagrammatic sketch for E shape threeway drainage tube.
The specific embodiment: existing known technology is partly still adopted in water inlet of the present utility model, so be omitted.Its water-drainage mechanism is seen Fig. 1, it is made up of E shape threeway drainage tube (1), rough undulation pipe (4), button (3), return spring (2), bath seat pipe (6) etc.The section of rough undulation pipe (4) is circle, makes with whippy rubber, E shape threeway drainage tube (1) is made of plastics, the central of it is that circle, both wings are oblate (seeing accompanying drawing 2), the lower end of rough undulation pipe (4) tightly is enclosed within the suitable for reading of bath seat pipe (6), the upper end then tightly is enclosed within on the central round mouth of E shape threeway drainage tube (1), add the bottom that rubber washer (7) is fastened on water tank (8) together below the bath seat pipe (6), button (3) be located at tank lid (5) in the middle of, return spring (2) then be contained in button (3) below.Water level in the water tank (8), by known water intaking valve control, make its place suitable for reading a little less than rough undulation pipe (4).When washing by water, needs just press button by (3), rough undulation pipe (4) pressurized promptly can shorten sinking, E shape threeway drainage tube (1) also can limit, when rough undulation pipe (4) suitable for reading sinks to the water level that is lower than in the water tank (8), water promptly flows into by the both wings of E shape threeway drainage tube (1), pour water closet through rough undulation pipe (4) and bath seat pipe (6), produce little flushing action, if let go this moment, rough undulation pipe (4) promptly can reset in the resilience rising, makes the water level that exceeds suitable for reading, and bath is promptly ended, make E shape threeway drainage tube (1) submerged fully if press the button (3), promptly can form siphonage this moment, makes the water in the water tank (8) continue to flow into water closet, and the water level in water tank (8) is lower than the water inlet of E shape threeway drainage tube (1) both wings, till causing air to enter and siphonage being disappeared, bath just comes to an end.Therefore two grades of flushing functions of size are arranged, if the water level in the water tank (8) is too high, water also can flow into water closet through rough undulation pipe (4) again from E shape threeway drainage tube (1), and therefore leather has removed the bleed off pipe that the various flushing mechanisms of conventional known all must have.Therefore this water-drainage mechanism has also been got rid of valve block, is a kind of water-drainage mechanism of novel valveless, can infuse the end and eradicate because of discharging valve poor quality or the valve block various seepy questions that reason caused such as be not closed completely.Its structure is compared with existing various jettison gears and is also wanted much simple.
