Abstract

The utility model relates to a drain valve of a water tank for water saving toilets, which is characterized in that the drain valve of a water tank for water saving toilets is a half ellipsoid-shaped rubber bag; the wall of the half ellipsoid-shaped rubber bag is uniformly distributed with a plurality of elliptic through holes. Because the shape of the drain valve of a water tank for water saving toilets is an ellipsoid shape with through holes, when a switch is opened to discharge water, the elliptic valve is turned on under the action of pulling force and water in a water tank is discharged. After the switch is turned off, the pulling force acting on the elliptic valve is cancelled and the elliptic valve is returned to the original position by means of gravitational force and the impact force of water stream, so the goal of water saving is achieved. The utility model has the advantages of simple structure, easy fabrication, and convenient replacement, and can be applied in the existing water tank for toilets without changing the structure and the fittings of the water tank for toilets.

Description

Water-saving Cistern for toilet draining valve

The utility model relates to a kind of water-saving Cistern for toilet draining valve.

Present employed Cistern for toilet, its form of structure be as shown in Figure 1: it comprises water inlet pipe (1), water intaking valve (2), stay cord (3), switch (4), draining valve (5), the ball float (6) that is installed in the water tank, and during use, operating switch discharges water, flushing toilet bowl.The drawback of this mode is: because that draining valve is generally is one hemispherical, the rubber valve of lower ending opening, can't close after discharging water, current in the water tank such as have only intact, draining valve just can cut out voluntarily, it all is certain causing each displacement, promptly no matter wash just large and smallly, all used the water of equal number, waste just seems when dashing urine.Therefore, can develop a kind of draining valve that can suitably control displacement according to actual needs, cause relevant person's attention.

A kind of water-saving Cistern for toilet draining valve that the purpose of this utility model is developed at above-mentioned condition just, this drain valve structure is reasonable, and is practical and convenient, and people can discharge water according to actual needs in right amount, reach the purpose of water saving.

The purpose of this utility model realizes by following measure: the rubber bag tank that this water-saving Cistern for toilet draining valve is a semiellipsoid shape is evenly equipped with a plurality of open-works on the cyst wall.

Open-work is shaped as ellipse in the utility model.

The utility model is owing to the shape with draining valve is made into the ellipsoid shape that has open-work, when operating switch discharges water, ellipsoid shape draining valve is opened under the pulling force of stay cord, water in the water tank is promptly discharged, and after trip switch, acts on the pulling force cancellation on the draining valve, gravity used by draining valve and impulsive force (offers oval open-work on the ellipsoid, the water impact elliptical aperture applies power downwards to it), draining valve can reset, thereby reaches the purpose of water saving.1., practicality the advantage that the utility model is compared with prior art possessed is:: this ellipsoid shape drain valve structure is simple, and is easily manufactured, is applicable to existing Cistern for toilet, need not to change cisten mechanism and other accessory, and it is convenient to change.2., randomness: after using this draining valve, displacement can artificially freely be controlled fully, pulls (drawing) moving switch, and current are discharged, continue to impact urinal, in the time of need not washing, trip switch, current promptly stop.3., desirability: after using this draining valve, do not influence the original impact force of current, can guarantee urinal is rinsed well, guarantee using water wisely again, improved the utilization rate of water greatly.

The drawing of accompanying drawing is described as follows:

Fig. 1 is existing cisten mechanism diagrammatic sketch.

Fig. 2 is the structural representation of the utility model embodiment 1.

Fig. 3 is the vertical view of Fig. 2.

Fig. 4 is the structural representation of the utility model embodiment 2.

The utility model is described in detail below in conjunction with (accompanying drawing) embodiment:

Embodiment 1: as Fig. 1, Fig. 2, shown in Figure 3: present embodiment is suitable for existing lower water box, and the ellipsoid valve (7) that originally has oval open-work (8) is changed existing draining valve (5) among Fig. 1, fixes backguy and side gets final product.This ellipsoid valve has fixedly ear (9) (same as the prior art) of side.

Embodiment 2: as shown in Figure 4: present embodiment is suitable for existing high level cistern, adopt the direct cable formula of existing high level cistern, be that backguy links to each other with a pull bar, the pull bar lower end directly is inserted in the jack (10) of this ellipsoid valve upper end (inserting mode and position are all same as the prior art).

Claims

1, the utility model relates to a kind of water-saving Cistern for toilet draining valve, it is characterized in that: draining valve is the rubber bag tank (7) of a semiellipsoid shape, is evenly equipped with a plurality of open-works (8) on the cyst wall.

2, water-saving Cistern for toilet draining valve according to claim 1 is characterized in that: open-work (8) be shaped as ellipse.
