Abstract

The utility model relates to a double-function low level cistern for saving water, which can be used for flushing toilet with big or small water quantity, and the water quantity is accurate. The utility model is composed of a cistern, a handle, a water inlet, a water discharging valve, and a water draining pipe. The utility model is characterized in that the water discharging valve is composed of a siphon pipe, a fluidic device, an elbow, a valve clack, and a valve seat. The water discharge outlet of the cistern is sealed by the valve clack. When the valve clack is lifted less than 45 DEG, the fluidic device ejects water, siphonage is generated, and urine flushing is realized. When the valve clack is lifted more than 45 DEG, stool flushing is realized. The utility model has the advantages of simple structure, obvious water saving effect, and practicality, and the utility model can be used for reconstructing and replacing the existing cistern.

Description

Two way low lever cistern for saving water

The utility model belongs to sanitaryware, is specially adapted to water closet flushing tank device.

Domestic lower water box all adopts gram to leak valve at present, and its structure is the turnover panel of the tapered opening in below of rubber system, can not quantitatively control because gram leaks the lifting angle of valve, can't realize the flushing of branch size shelves.And the second gear of introducing in the patent that has flushing is actually at urine shelves (or stool shelves) and does not put by manually lifting handle, looses one's grip and then closes, and washing water quantity is decided because of people's sensation.Like this, little shelves flushing is not that discharging quantity of water is many on can not being controlled at quantitatively, is exactly that discharging quantity of water is not enough.Be that water-saving result is not obvious or do not reach flushing scrubbing requirement, also have and adopt eccentric wheel in the grip, but little shelves washing water quantity still can not quantitatively wash.External advanced lower water box equipment is that have roughly the same with lower water box equipment China existing use, though have can realize two grades of flushings, complex structure, the manufacturing cost height, maintenance difficult is not suitable for China's national situation.

The purpose of this utility model is, a kind of difunctional water saving lower water box that can divide two grades of flushings automatically is provided, and it is simple in structure, Nover practical, and water-saving result is obvious, and can transform, change old-fashioned water tank.

Difunctional water saving lower water box of the present utility model is made up of water tank, handle, water inlet, draining valve, gutter, it is characterized in that:

The draining valve that is positioned at the water tank middle part is made of syphon, ejector, elbow, flap, valve seat, a siphonal end be funnelform ejector and be connected by an elbow, the other end is the water sucking mouth of control cistern water level height, the other end of elbow is connected with valve seat, the elbow outer wall is provided with one group of pivot pin, the hollow hemispherical flap of rubber system, an end has two brackets, is hung on two pivot pins of elbow; Ejector is fixed on the valve seat mouth, and the ejector outer wall is curved slightly, with the distance of valve seat periphery be 4～10 millimeters, the valve seat bottom is connected with gutter; Handle is made of filler ring, eccentric shaft, shadoof, stepping direction board, and eccentric shaft is circular, and wheel has chute in week.

Described flap is that hollow is flat.

Described syphon has an aperture on the water sucking mouth.

Spacing the best of described ejector and valve seat periphery is 6～8 millimeters.

The course of work of the present utility model is: when draining valve was not worked, the flap buckle closure was sealing state on ejector, during bath, pull the stepping washed handle, shadoof is mentioned flap by tether, when the angle of eccentric shaft rotation was spent less than 45, promptly the urine shelves were located, and discharging quantity of water is 4.5 liters, when promoting, produce jet, form siphon, when water level dropped to syphon aperture place, siphon was destroyed, and flushing stops, flap falls, and recovers sealing state, and water inlet begins water inlet; When handle being pulled big shelves place, angle is greater than 45 degree, and the water of water tank pours urinal by ejector, and syphon water outlet simultaneously realizes the flushing of one case water (9 liters).

The utility model is owing to be provided with syphon, and control water level is come in available siphonal water sucking mouth, promptly controls little shelves discharging quantity of water, realizes difunctional cistern water-discharging; The aperture that top, syphon water sucking mouth is provided with can destroy siphon before the small water-stop bath finishes, suppress the current noise; Produce jet when flap promotes, cause negative pressure, form siphon; The wheel week of eccentric shaft is provided with chute, avoids dislocation, the swing of control shadoof.

Difunctional water saving lower water box of the present utility model has automatic ration, the dual-use function of stepping flushing, water-saving result is remarkable, as calculating by a tame four-hole people, goes to toilet for each person every day 6 times, wherein urinate for 5 times, the sanitary water amount is 31.5 liters for each person every day, shared 126 liters/day of four-player.Compare with single grade of water tank (9 liters), can economize on water 2.7 tons in every month, 8.1 tons of everyone year water savings.Family of four can be economized on water 32.4 tons every year, calculates by 1,000 ten thousand populations as Beijing, can economize on water 8,100 ten thousand tons every year, and water per ton is by 0.30 yuan of calculating, and then Beijing can save 2,430 ten thousand yuan of water rates, remarkable in economical benefits every year.

The utility model can be used for lower water box, also can be used to change old-fashioned cistern fittings.

Below in conjunction with drawings and Examples difunctional water saving lower water box of the present utility model is described further.
