Abstract

An automatic toilet water flusher includes a pipeline, a water inlet and a water outlet. The utility model is characterized in that a pedal is also included, a press type damping valve and a normal open stop valve are arranged inside the pipeline, the control rods of the press type damping valve and the normal open stop valve are connected immovably with the bottom of the pedal; a return spring can be connected between the pedal and the pipeline,, the return spring is positioned at one side of the press type damping valve. The utility model realizes that the flusher can be closed when the person uses the toilet, and after the person leaves, the toilet can automatically timing flush, thereby the toilet is sanitary and need no special operation, the application is very convenient; at the same time, the utility model is simple in structure, the cost is equal to the common water faucet, so as to be suitable for the wide popularization.

Description

Automatic toilet bath device

Technical field

The utility model relates to a kind of lavatory flushing equipment, is specifically related to a kind of foot-operated lavatory bath device.

Background technology

In the public lavatory, for ensureing public health, avoid disease propagation, adopt the bath equipment of pedal control usually.At present common have two classes, and a class is simple foot valve, when needing bath, and the pedal that tramps with one's feet, water promptly flows out, but often the someone does not want to take the trouble and does not wash by water; Another kind of is the pedal double as control panel of using urinal, a kind of automatic flushing device is after an action of the bowels disclosed as Chinese patent CN86208158U, include water tank, pedal is connected with control valve, wherein spool control twice valve when pin steps down on the pedal at one's leisure, is opened water intaking valve, beginning is to water tank water intake, when the people leaves, close water intaking valve, open discharging valve, urinal is washed by water, this class flushing device can be realized auto-flushing, but water tank need be set, and structure is complicated, it is bigger to promote the use of cost in the public lavatory, can't satisfy the transformation in a large amount of public lavatorys.

Summary of the invention

The utility model purpose provides a kind of simple in structure, the automatic toilet bath equipment that cost is low.

For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic toilet bath device, comprise pipeline, water inlet and delivery port, also include a pedal, be provided with a pressing orifice valve and one in the described pipeline and often open stop valve, the valve rod of described pressing orifice valve and Chang Kai stop valve is fixedlyed connected with the pedal bottom.

In the technique scheme, described " pressing orifice valve " is a kind of orifice valve, and valve rod is pressed the back under the water filling situation, because damping action, valve is with time-delay closing; Described " often opening stop valve " is a kind of valve that two states is arranged, and is in conducting state at ordinary times, and when valve rod was stressed, valve was in cut-off state, when control lever external force is removed, replys conducting state rapidly under spring action.During use, the foot rest in the pedal double as lavatory of bath device is when the human lavatory, pedal is depressed, and the pressing orifice valve is opened, and stop valve is stressed closes and often open, the bath device is obstructed, when the people left, external force was removed, and it is open-minded often to open the stop valve return, begin bath, because the effect of damping, orifice valve will keep the conducting state of certain hour, close automatically at last.

In the technique scheme, described pedal and pipeline enclosure can be connected with back-moving spring, and described back-moving spring is positioned at pressing orifice valve one side; Be provided with spacing preiection at pedal or pipeline upper reset spring place.The setting of spring and spacing preiection is in order to protect spool, to avoid spool stressed excessive and impaired, simultaneously pedal being resetted fast.

In the technique scheme, described pressing orifice valve comprises the gland of screw fixed in conduit upper, be slidingly mounted on the valve rod in the gland center cavity, the valve rod top is fixed with collar, be provided with spring between collar and gland, the lower end of valve rod is provided with spool, and described spool comprises sealing ring and damping rubber circle.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because the utility model is provided with and often opens stop valve, realized that the bath device cuts out with the lavatory time, self-timing bath when the people leaves, both health needn't specially be operated again, and was easy to use;

2, the foot-operated flushometer of the utility model and existing water tank type relatively, structure is simplified greatly, cost and ordinary faucet are suitable, thereby are suitable for large tracts of land and promote the use of.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: shown in accompanying drawing 1, a kind of automatic toilet bath device, comprise pipeline, water inlet 1, delivery port 2 and a pedal 3, be provided with a pressing orifice valve 4 and one in the described pipeline and often open stop valve 5, the

valve rod

8,13 of described pressing orifice valve 4 and Chang Kai stop valve 5 is fixedlyed connected with pedal 3 bottoms; Described pedal 3 is connected with back-moving spring 6 with pipeline enclosure, and described back-moving spring 6 is positioned at pressing orifice valve 4 one sides; Pipeline upper reset spring 6 places are provided with spacing preiection 7.

Wherein, pressing orifice valve 4 and Chang Kai stop valve 5 can use existing valve arrangement, in the present embodiment, often open stop valve 5 and comprise valve rod 8, spool 12, be fixed with rubber washer 9 on the spool 12, valve rod 8 tops are fixed with top flat 11, top flat 11 and valve body pipeline enclosure are provided with spring 10, at ordinary times, and under spring 10 effects, spool 12 is in a high position, the valve conducting is done the time spent as external force, and valve rod 8 is subjected to drops, rubber washer 9 sealing delivery ports, valve breakdown; Pressing orifice valve 4 comprises the gland 18 of screw fixed in conduit upper, be slidingly mounted on the valve rod 13 in gland 18 center cavities, valve rod 13 tops are fixed with top flat 14,18 on top flat 14 and gland are provided with spring 15, the lower end of valve rod 13 is provided with spool, and described spool is provided with sealing ring 16 and damping rubber circle 17.

Be further simplified structure, the top flat on above-mentioned two valve rods also can be cancelled, and directly replaces the function of top flat with the pedal after installing.
