Abstract

The utility model relates to an automatic timed flushing device for public toilet, which is mainly composed of an electromagnetic flushing valve and an electric control block. The utility model is characterized in that the automatic timed flushing device for public toilet can automatically time and achieve the flushing water of a urinal; the utility model can also conveniently flush water and clean the urinal through an artificial press to reset press-button at any time.

Description

Automatic timed flushing device for public toilet

The utility model belongs to sanitation of environment machinery.

Present public lavatory, city is the station especially, harbour, the park, the tourist attraction, closet stall in the public lavatory of occasion that the crowd is dense in cinema etc. is to belong to plough groove type, can use for many people simultaneously, its flushometer has plenty of the stay-supported of use high level cistern, has plenty of the knob of use running water pipe, the two common shortcoming is to need the manually-operated bath, because the people who goes to toilet constantly constantly, if everyone goes operation, then waste a large amount of water, if the people with the lavatory has dependent mentality, everybody thinks that I will cause unmanned bath at the do not wash by water words that someone will wash by water, cause sanitary condition to worsen.Especially the high-order cistern of stay-supported, because the relation of structure, number of operations more than will cause poorly sealed, perhaps evaporating, emitting, dripping or leaking of liquid or gas, the running water that perhaps gurgles causes the energy and water source to be wasted in a large number.

The purpose of this utility model provides self-timing flushometer a kind of simple in structure, easy to use.It can not only self-timing realizes the bath of urinal, also can manually push push button easily, carries out the bath cleaning of urinal at any time.Not only kept health but also saved the water source.

The utility model is achieved in that

When with the high level cistern flushing toilet bowl, utilize electric control box to control the electromagnet that is installed on the high level cistern automatically and carry out power on/off, when energising, electromagnet core up moves, when outage, electromagnet core is down action under action of gravity, because electromagnet core is connected with the Water flushing for cistern valve, thereby the action clocklike of electromagnet core just makes the Water flushing for cistern valve clocklike carry out opening and closing, realizes the self-timing bath.When the pressure tap water that directly utilizes water supply pipe carries out flushing toilet bowl, the bi-bit bi-pass normally closed solenoid valve (market stock in hand) of the DF1 series of should connecting between water supply pipe and closet stall bath pipeline, the keying of this electromagnetic valve is still controlled with electric control box.

Electric control box mainly is made up of the time relay and auxiliary reclay, and two time relays have been controlled the time of the opening and closing of electromagnetism flushing valve respectively.

As shown in Figure 2, the time-delay constant open contact of time relay IJS is connected into series loop with the electromagnet coil DT and the power supply that link flushing valve, moving the closing the shut-in time of having controlled flushing valve of time-delay of IJS time-delay constant open contact, auxiliary reclay coil IJZ and time-delay constant open contact IJS, time-delay constant close contact 2JS are connected into series arm, the constant close contact of intermediate relay I JZ and time relay IJS are connected into series arm, the constant open contact of intermediate relay I JZ and time relay 2JS also are connected into series arm, insert power supply by K switch after three series arm parallel connections.The moving disconnected opening time of having controlled flushing valve of the time-delay constant close contact of time relay 2JS.

Push button A connects with the coil of auxiliary reclay 2JZ, after can realizing manually pushing A, makes device convert Artificial Control bath state to by self-timing bath state.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of this self-timing flushometer.(1) is ball float water inlet assembly among the figure, (2) be high level cistern, (3) be inlet channel, (4) be electric control box, (5) be electromagnet, (6) be electromagnet stent, (7) are the action iron core of electromagnet (5) and the iron wire that is connected of flushing valve guide rod (8), and (8) are the flushing valve guide rods, (9) be the flushing valve guiding cap, (10) for pressing valve spring, (11) are the flushing valve guide cylinder, and (12) are flushing valve, (13) be the bath valve seat, (14) be jet water spout back of the body cap, (15) are bath pipeline, (16), (17) be rubber gasket.

Fig. 2 is the electric control theory figure of self-timing flushometer.As shown in Figure 2, RD is a fuse, and A is a push button, and IJZ, 2JZ are auxiliary reclay, and IJS and 2JS are the time relay, and K is a switch, and DT is the electromagnetic coil of electromagnet among Fig. 1 (5).

Now operating principle of the present utility model is described in conjunction with Fig. 1 and Fig. 2.

As shown in Figure 2, when closing K switch, time relay IJS gets, it is often opened time-delay contact IJS and will close by giving moving after the delay time of adjusting is earlier delayed time, the electromagnetic coil DT of electromagnet this moment (5) gets, cause the iron core action of the electromagnet (5) among Fig. 1, by (7) and flushing valve guide rod (8) flushing valve (12) is opened, begin to wash by water, almost in electromagnet action, in get with relay IJZ coil, its normally closed interlock IJZ is disconnected, time relay IJS outage this moment, its time-delay contact resets, and the constant open contact of IJZ is moving to be closed, cause time relay 2JS to get, its normally closed time-delay contact is moving disconnected by giving time of adjusting earlier, this moment the IJZ dead electricity, its normally open contact recovers often to open, this moment electromagnetic coil DT dead electricity, cause the iron core of electromagnet among Fig. 1 (5) to put down, make the flushing valve closure, this moment, bath finished.Meanwhile, it is normally closed that the normally closed interlock of IJZ recovers, the 2JS dead electricity, and its normally closed time-delay contact recovers normally off, causes this flushometer and finishes a working cycles.Like this, the automatic open and close that flushing valve can go round and begin again is finished the bath work of lavatory urinal self-timing.

The length of time relay IJS control flushing valve shut-in time, can adjust according to the people's who uses the lavatory quantity situation, 2JS controls flushing valve opening time length, and the difficulty when this can defecate according to flushing and the size of water tank volume are adjusted.

If the flushing in public lavatory is not to use high level cistern, but utilize thicker water supply pipe, as long as connect a DF1 type bi-bit bi-pass normally closed solenoid valve (market is in stockit is available) in water supply pipe, electric control circuit is constant so.

When not needing the keying of self-timing control flushing valve, when sweeping the lavatory health as the workman, can manually push the button A among Fig. 2, this moment, auxiliary reclay 2JZ got electricly, and its constant close contact is moving disconnected, makes IJS, IJZ, 2JS dead electricity, automatic timing circuits is inoperative, and the constant open contact of 2JZ is moving fashionable, and it is electric that DT is got, and iron core pulling flushing valve (12) unlatching of the electromagnet (5) among Fig. 1 is washed by water.If button A resets, whole device will return to self-timing bath state again.
