Abstract

The utility model provides an improved water-on and water-off controller for a water tank, in particular to the water-on and water-off controller for the water tank of a sitting flush toilet. The water-on and water-off controller for a water tank is provided with the fan-shaped cam control gear of a push rod which is connected with a handle shaft; when the opening of a sewer pipe is opened to flush water, a floating ball-type water valve can be controlled without discharging the water by the fan-shaped cam control gear of the push rod; after flushing, the daily sealing of the opening of the sewer pipe can be kept by an elastic element which is positioned on a clogging leather cup rod. Compared with the general water-on and water-off controller for the water tank, the utility model has the advantages that the water flushing quantity can be controlled, the loss of the drainage and the water leakage can be reduced and the water can be saved; the water-on and water-off controller for a water tank also has simple operation.

Description

Water-on and water-off controller for water tank

The utility model relates to a kind of upper and lower water controller of water tank of improved water tank upper and lower water controller, particularly sitting type water closet.

Upper and lower water controller at present known sitting type water closet (the having another name called lavatory pan) water tank is that because ball float has just been opened water intaking valve with falling under water, the water-white whitecap of emitting has taken when sewer pipe mouth obstruction leather cup is mentioned bath; The leverage that is connected with the Handle axis square hole act as and mentions, puts down the obstruction leather cup in addition, and the sewer pipe mouth is discharged water or water storage.But owing to be rigid connection between this class bar, cause like this and need move several times that handle just can make leather cup block the sewer pipe mouth, block sometimes, leather cup is put less than the sewer pipe mouth at all, sometimes leather cup has put down, but bad with the sealing of sewer pipe mouth, causes seriously and leaks.

The purpose of this utility model is to provide a kind of improved water tank upper and lower water controller, and it has overcome the shortcoming of above-mentioned water tank control device, has prevented sluicing, has leaked, thereby saved water.

Its solution is: a controlling organization is set on Handle axis, and this mechanism is the fan-shaped cam of push rod, lays flexible member on obstruction leather cup bar.When handle rotated bath, cam was pushed down the valve stamen top on the float-ball type water valve earlier, and water is closed, and push rod promotes shifting fork bar then, makes its rotation, drives leather cup and rises, and opens the bath of sewer pipe mouth; When handle when closing direction rotates, stop up the flexible member of laying on the leather cup bar and make leather cup fall to blocking the sewer pipe mouth and make down mouth of a river good seal by elastic force, the ball float sinking makes and enters valve and open into water then.These improve, and have overcome the leakage water shortcoming of original device, have saved water.

The utility model describes in detail embodiment below with reference to accompanying drawing:

Fig. 1 is the front view of an embodiment of the utility model;

Fig. 2 is the vertical view of an embodiment of the utility model;

Fig. 3 is the fan-shaped cam master of push rod of the present utility model, bow, left view;

Fig. 4 is location rod member master of the present utility model, vertical view;

Fig. 5 is shifting fork bar master of the present utility model, vertical view.

With reference to accompanying drawing 1 and accompanying drawing 2, location rod member 9 is loaded in the water tank wall square hole, and the screw thread external member 14 that has rubber seal 15 is inserted in the hole, garden of backstay 9, and tightens up with nut 13; Handle axis 11 is contained in screw thread external member 14 endoporus, and rotatable.The controlling organization that is provided with on Handle axis is the fan-shaped cam 10 of push rod, and cam angle degree is 70 °～80 °.(fan-shaped cam is α by the dress angle ₂＞α ₁), with securing member for example screw 12 connect firmly with Handle axis 11.Shifting fork bar 8 is through on the Handle axis 11, and is arranged in the groove of the fan-shaped cam 10 of push rod.Guide 3 usefulness screws 4 are clamped in crossing on the water level gutter 2 on the sewer pipe; Stopping up the guiding circular hole of the bar of leather cup 5 by guide 3, stopping up the flexible member of laying on the leather cup, is the element that rubber-like metal material or nonmetals are made for example, and for example uses the spring 6 of steel wire coiled.Channel nut 7 is contained in and stops up leather cup 5 masthead ends, and places in shifting fork bar 8 grooves.

Another embodiment of the present utility model:

One torsion spring is loaded on the Handle axis 11, and the torsion spring two ends are fixed on Handle axis 11 and screw thread external member 14 respectively, and then Handle axis 11 is reset to automatically and carries out.Water tank among the last embodiment is raised, and Handle axis 11 pommels are worn a stay cord, just can be used for the water tank of stay-supported joystick axle, for example as crouching formula toilet flush or the upper and lower water controller of public lavatory water tank.

The utility model compared with prior art has following advantage:

Mention when discharging water owing to stop up leather cup, water intaking valve is closed, using water wisely; The obstruction cup packing is good, has prevented from again leaking, and is so water-saving result is splendid, easy to operate.

Claims

1, the upper and lower water controller of water tank, the upper and lower water controller of the water tank of sitting type water closet particularly, constitute by the controlling organization on float-ball type water valve, obstruction leather cup, shifting fork bar, Handle axis and the axle, it is characterized in that controlling organization on described Handle axis and the axle is the fan-shaped cam of push rod that is assemblied on the Handle axis and can rotates with Handle axis, by the shifting fork bar in Handle axis control cam angle degree and the fan-shaped cam path of push rod, drive and stop up leather cup rising or decline, on the obstruction leather cup bar flexible member is set and makes its leather cup and sewer pipe mouth good seal.

2, a kind of by the said control device of claim 1, it is characterized in that the fan-shaped cam angle degree of said push rod is 70 °～80 °.

3, a kind of by claim 1 or 2 said control device, it is characterized in that stopping up the flexible member that is provided with on the leather cup bar is that rubber-like metal, nylon or elastomeric material are made.
