CN2471843Y - Two stage water saving discharger for low cistern of toilet - Google Patents

Abstract

The utility model relates to a water-saving drainage which can realize two water flows in water tank drainage as required and prevent leakage, providing a novel two-section drainage control mechanism (1) and a siphon drainpipe (4) which are connected and combined as a whole by a lever(3); the utility model is a water-saving drainage which can drain as required and prevent leakage. The utility model is a siphon drainage without drain valve, and is not leaked because of the quality and abrasion of the drain valve. By utilizing a fan-shaped projection at the shaft of the two-section drainage control mechanism, the rotary angle is different in two different fan-shaped slots inside the outer sleeve, and different water displacements can be realized according to the different depth of which the control siphon tube drops into the water tank. A turning handle (2) can realize small displacement, and the turning handle can realize large displacement by pushing the shaft inwards. When the drainage is complete, the spring can push the shaft into the position of small displacement automatically.

Description

Low cistern for closet bowl two-part water saving dewatering installation

The utility model relates to a kind of low level cistern draining can realize two kinds of water yields as required, prevents the water saving dewatering installation that leaks.

Low cistern for closet bowl draining system drives lever by handle, carries line and mentions the draining valve realization.Draining valve is once mentioning, and water flows out from outfall, and 9 to 13 premium on currency flow the clean draining valve original position that just can fall back in the water tank, block outfall again.Dash stool and want 9 to 13 premium on currency, need only 4 to 6 liters and dash urine, so cause waste.Because draining valve fabricating quality and use wearing and tearing often have bad sealing to leak.

To dash waste that urine water cause water in order solving more, to adopt two kinds of displacement towards excrements.Popular on the drainage mechanism market of two kinds of water yield drainings is to be realized by two buttons that are contained on the tank lid; Can prevent that the siphon drainage pipe that leaks also has product.But both exist separately.

The purpose of this utility model is to provide a kind of new two-part drainage control mechanism and siphon drainage pipe combined integrated, realizes pressing different needs, the water-saving dewatering installation that component draining and preventing is leaked.

The utility model is made up of two-part drainage control mechanism and siphon drainage pipe two parts.Both are linked to be an integral body with lever.The two-part drainage control mechanism is made up of overcoat, axle and spring.Fan-shaped bump of circular shaft stage casing band, leading portion stretches out overcoat, and the end is square, the peace handle.Back segment stretches out overcoat after passing spring, and the end also is square, connects lever.There are two different angles, the fan groove that is interconnected in the fan-shaped bump position on the interior respective shaft of overcoat.Fan-shaped bump can only rotate the angle of setting in fan groove.The width of fan groove is wideer slightly or identical than the fan-shaped bump thickness on the axle.Low-angle fan groove is preceding, the fan groove of wide-angle after.Under the thrust of spring, the fan-shaped bump on the axle is parked in the low-angle fan groove, and when axle changeed, because of being subjected to the restriction of fan groove angle, the angle that can change was little, makes that the degree of depth in the siphon drainage pipe descending water that the lever other end connects is little, has just realized little displacement.When push shaft inwards, spring is compressed, axially in play, fan-shaped bump moves on to wide-angle fan groove position.The angle that axle can change is big, and the degree of depth in the siphon drainage pipe descending water that the lever other end connects is big, has just realized big displacement.After draining was finished, under the promotion of spring, fan-shaped bump reset in the low-angle fan groove on the axle.

Design the fan groove of different angles, can realize two kinds of displacement of any proportioning.

Siphon drainage pipe is made up of U-shaped pipe and bellows.U-shaped pipe and lever are for being flexible coupling, and bellows couples together U-shaped pipe and water tank outlet.

The size of two-part drainage control mechanism of the present utility model and common draining handle are more or less the same.Can be installed in GB GB6953-86＜sanitary ceramics specification and connection dimension〉in the handle hole of 1.3 low level cistern regulations.Realize two sections draining controls in a mechanism, volume is little, and is simple in structure, easy to use.Component control, siphon drainage, water is used effectively, and avoids waste, and has realized using water wisely.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Below in conjunction with details and the working condition of Fig. 1 _ 6 detailed descriptions according to the concrete device that the utility model proposes.

The utility model comprises two-part drainage control mechanism (1) and siphon drainage pipe (4) two parts.The two-part drainage control mechanism is fixed in the handle hole of water tank wall with nut (8).Drainage control mechanism is made up of overcoat (7), circular shaft (5) and spring (6).There is the fan-shaped bump (see figure 5) of an angle γ in the circular shaft stage casing, and leading portion stretches out overcoat, and the end is square, peace handle (2).Back segment passes spring and stretches out overcoat, and the end also is square, is connected with lever (3).The fan-shaped bump position fan groove (see figure 5) that to open an angle be β on the respective shaft in the overcoat.It is wide slightly that the axial width of fan groove is gone up fan-shaped bump thickness than axle, or identical.The then β angle fan groove fan groove (see figure 6) that to open an angle again be α.The top of two fan grooves is same planes.The α angle is greater than the β angle.

Siphon drainage pipe (4) is made up of U-shaped pipe and bellows.U-shaped pipe and lever are flexible coupling.Bellows couples together U-shaped pipe and water tank outlet.

When being full of water water level shown in Fig. 1 water surface curve in the water tank, press handle, turning cylinder drives lever the U-shaped pipe is pressed into underwater formation siphon drainage.Descend with the water surface, the U-shaped pipe falls.Change by the lever drives axle, and fan-shaped bump commentaries on classics on axle (β-γ) spend the angle, projection is subjected to the restriction of fan groove, and axle stops operating, and lever is held the U-shaped pipe and is no longer descended with the water surface, makes siphon destructive, the draining termination.Finished little water yield drainage procedure.The water tank water-filling, under the effect of buoyancy and bellows self elastic force, the U-shaped pipe returns to the state of (Fig. 1) before the draining.Push shaft makes the position of fan-shaped bump to the B-B section inwards.Press handle axis of rotation, drive lever the U-shaped pipe is pressed into water surface formation siphon drainage.Fall with water surface decline U-shaped pipe.On axle fan-shaped bump change (angle of α-γ), projection is stopped operating by the restriction of fan groove, the U-shaped pipe no longer descends with the water surface, makes siphon destructive, draining stops.Finished the big yield drainage procedure.The water tank water-filling, the U-shaped pipe returns to the draining front position, promotes lever, and axle also sets back, and under the promotion of spring, fan-shaped bump is got back to the A-A profile position on the axle.(angle of α-γ) is greater than (the angle of β-γ).Make U-shaped pipe height of drop difference, realized different displacement control.
