Description

Automatic flushing cistern

The utility model relates to the automatic flushing cistern field.

Market existing slot type stool purging method, the general tipping bucket siphon water tank that adopts, size by feed-water valve controlled water flow amount, i.e. upset after tipping bucket is full of water, until cistern water level reaches priming level, water tank begins the draining flushing, pumpway is every being by the decision of the flow of water supply system pressure and valve opening, under the constant condition of valve opening amount, the water use peak phase, water supply system pressure descends, flow diminishes, flushing is long at interval, and hygiene effect is poor, otherwise flushing frequency quickening (especially night is under unmanned situation about using) water resource waste is big.

The purpose of this utility model is exactly in order to address the above problem, and a kind of automatic flushing cistern of saving water source, sequential automatic control, sanitation and hygiene is provided.

Foregoing invention purpose of the present utility model realizes by following technical proposals:

Automatic flushing cistern, comprise casing, water inlet pipe, outlet pipe, tipping bucket, it is characterized in that forming by plug valve of forming by valve body, spool, the fork that has ball float and micro actuator and adjuster that is equipped with between the water-in and water-out mouth of pipe and the sequential self-con-tained unit and several parts of electromagnetic valve that are contained in the outer upper face of casing.

Described plug valve is made up of valve body, spool, the fork that has ball float and micro actuator and adjuster, its purpose is to have designed with the ball float pendulum angle matches gives aquaporin, with ball float and fork is arm of force controlled valve, when the water supply system variation in water pressure, valve energy positiver sealing, cistern water level is constant, can guarantee that water tank reaches priming level, can prevent from again to reach the effect of saving the water source because of the close running water phenomenon that sternly do not cause of valve envelope.Upper face is provided with electromagnetic valve and sequential self-con-tained unit outside casing in addition, so just can make the sequential self-con-tained unit make the tipping bucket upset according to predefined washing time control electromagnetic valve energising, reaches regularly flushing, the purpose of sanitation and hygiene

As a kind of improvement, angle between the water-in and water-out mouth of pipe on the described plug valve valve body is the right angle, spool is that the garden is tapered, and the angle of its water-in and water-out passage is 110 °～115 °, is equipped with fork, adjuster and the locking nut of band ball float and micro actuator on the screw thread diameter of axle of spool one end.When water level in the casing rises, be the rotation that the arm of force drives spool with ball float and fork like this, the intake tunnel that spool and valve body are formed is closed gradually, and when water level rose to priming level, plug valve cut out fully, reached the purpose of saving the water source.

For the position that guarantees accurately, reliably, conveniently debugs fork and ball float makes its complete cut-out tap valve when water tank reaches priming level, and then guarantee under the situation that water system pressure changes, cistern water level is constant, and contacted two end faces of fork that are arranged on adjuster and band ball float and micro actuator on the screw thread diameter of axle of spool one end are a pair of radioactivity end face ratchet

In order to adjust the position of ball float more accurately, being located at ball float, connect auspicious micro actuator with fork be the fine thread structure.

In order to realize timing automatic flushing, the contact that is contained in the electromagnetic valve of the outer upper face of casing contacts with the shank of the tipping bucket of horizontal positioned, and the input of electromagnetic valve is connected with the output of the sequential self-con-tained unit that is located at its below.Like this when the casing water-filling, before not reaching priming level, tipping bucket is owing to the effect of its center of gravity can not overturn always, have only the flushing set when the sequential self-con-tained unit of control electromagnetic valve then constantly, send signal and make the electromagnetic valve energising, touch the tipping bucket upset and realize flushing automatically, the flushing rear dump recovers level, water level and ball float in the casing drop to minimum point, and fork drives valve core rotation, and intake tunnel is opened, by advancing, outlet pipe is water-filling in tipping bucket, water level and ball float in the casing are risen gradually, close fully and stop water-filling until reaching the priming level plug valve, next flushing of setting of sequential self-con-tained unit by the time arrives constantly and begins flushing process again.It day be to washing time that the sequential self-con-tained unit can be designed as to work by day, according to the rules of life of the morning, noon and afternoon flushing density district that is ranked, wash the interval from 30 minutes to 24 hours disposable being ranked of scope internal variable, guarantee the automatic flushing that goes round and begins again.

By the utility model of said structure, has the advantage of saving water source, automatic flushing, sequential automatic control.

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

Embodiment 1:(per half an hour of Cistern flushing once)

Automatic flushing cistern, comprise casing 1, water inlet pipe 2, outlet pipe 3, tipping bucket 4, by advancing, be equipped with between effluent pipe mouth by valve body 14, spool 11, having the fork 6 of ball float 8 and micro actuator 7 and the plug valve 5 that adjuster 12 is formed and the sequential self-con-tained unit 10 that is contained in casing 1 outer upper face and electromagnetic valve more than 9 parts forms, advance 2 on the valve body 14, the angle that effluent pipe mouth is 3 is the right angle, spool 11 is that the garden is tapered, it advances 17, the angle of exhalant canal 16 is 112 °, is equipped with the fork 6 of band ball float 8 and micro actuator 7 on the screw thread diameter of axle of spool 11 1 ends, adjuster 12 and locking nut 13.Adjuster 12 is a pair of radioactivity end face ratchet with fork 6 contacted two end faces, and being located at ball float 8, connect auspicious micro actuator 7 with fork 6 be the fine thread structure.The contact 15 of electromagnetic valve 9 contacts with the shank of the tipping bucket 4 of horizontal positioned, and the input of electromagnetic valve 9 is connected with the output of the sequential self-con-tained unit 10 that is located at its below.The sequential self-con-tained unit 10 of control electromagnetic valve is by 24 hours to be the quartz clock, rechargeable battery in a week, to be that to be carved with width 0.2mm length on the garden dish of 75mm be that 12mm is spaced apart several parts of entad groove, optoelectronic switch and integrated circuit of 7.5 ° and forms at diameter.
