Description

Automatic washing device for urinal

The utility model relates to a kind of switch that utilizes infrared controlled gate valve, realizes the device of urinal automatic flushing.

Lavatory flushing device in present hotel or the office building, general urinal adopts the running water formula, and promptly no matter there is nobody to go to toilet, water pipe is the flowing water flushing toilet bowl always, and water supply volume is very big, and easily spatters people's clothing footwear with water.The closet stall flushing the toilet after use must the very important person remove to draw back water valve, the valve of existing machinery formula, because pulling force is inhomogeneous, direction of pull is incorrect, very easily causes mechanical breakdown.Utilize water tank inner float ball drive noticeable degree cistern water level, because the buoyancy size is difficult for adjusting, needle-valve is easy to wear, is not closed completely, and very easily leaks, and this is the main cause of the present flush toilet serviceability rate lower (being lower than 60%) that uses.Simultaneously many people use, and spread disease easily, and are unhygienic.

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of infrared rays water valve control device is provided, and the realization urinal is automatically washed by water.

The major technique formation that realizes above-mentioned purpose is that this device is made up of electromagnetic valve, the infrared rays sending and receiving apparatus of power supply, rectifying and wave-filtering integrated stable voltage circuit, photoelectric conversion amplifier, delay timing control circuit, on-off circuit, control water valve.

Elaborate below in conjunction with accompanying drawing:

Fig. 1 is a logic chart of the present utility model.

Fig. 2 is delay timing control circuit figure.

Fig. 3 is electromagnetic valve one a quiet floatage control device schematic diagram.

As shown in Figure 1, civil power divides three tunnel outputs behind rectifying and wave-filtering integrated stable voltage circuit 1 rectifying and voltage-stabilizing, a road direction photoelectric conversion amplifier 2 power supplies, 3 power supplies of the second road direction delay timing control circuit, another road direction on-off circuit power supply.Be installed in the RF transmitter 5 at urinal two ends and infrared signal that receiver 7 will collect human body 8 by photoelectricity walk around change 2 pairs of signals of amplifier and amplify processing after, wash by water by 9 pairs of urinals of delay timing control circuit 3 starting switch circuit, 4 control electromagnetic valve, indicator lamp 6 is used for the signal indication.For the water halter flushing of general lavatory, repacking electromagnetic valve 9 gets final product on the water halter; Valve for the bucket that draws water is used electromagnetic valve instead, and when on-off circuit started, electromagnetic valve was opened, and to cistern water supply, its water level is raise, and ball float buoyancy increases, and drives discharging valve and opens.

Because the photoelectric conversion amplifier 2 of power supply rectification filter integrated stable voltage circuit 1, infrared rays sending and receiving apparatus 5,7 and processing infrared signal all belongs to known circuit, this manual just is not described in detail, with regard to delay timing control circuit 3 shown in Figure 2, on-off circuit 4 describes in further detail below.

As shown in Figure 2, infrared signal is held input amplifier IC by B after photoelectric conversion amplifier 2 is handled ₁, IC ₁Output relay termination J ₁, delay circuit R ₁C ₂, R ₂C ₂By relay J ₁Normally closed, constant open contact J _1-4, J _1-3Control, time delayed signal is by A end input amplifier IC ₂, IC ₂Output relay termination J ₂, J ₂Constant open contact J _2-1Constitute on-off circuit with electromagnetic valve DF.Simultaneously, J ₁Constant open contact J _1-2, constant close contact J _1-1Be connected in series red, green indicator lamp D respectively ₂, D ₁

Its operating principle roughly is, when the people goes to toilet, after infrared signal is handled and amplified, by amplifier IC ₁, make relay J ₁Must be electric, J _1-2Closure, red indicator lamp D ₂Bright, expression has the people, corresponding J _1-1Open, unmanned signal is beaten D ₁Go out; J _1-3Closure, J _1-4Disconnect R ₁C ₂Constitute delay circuit and (adjust R ₁C ₂The capacitance-resistance value can adjust delay time), power supply is to C ₂Charging; After the people left, infrared signal disappeared, J ₁Dead electricity, J _1-1Closure, green light is bright, J _1-3Disconnect J _1-4Closure, capacitor C ₂Pass through resistance R ₂To IC ₂Power supply, J ₂Must be electric, J _2-1Closure, then water valve is opened in the electromagnetic valve energising, realizes auto-flushing.

For the signal triggering valve switch that the people who prevents from not go to toilet sends, adjust R ₁C ₂The capacitance-resistance value can set capacitor C ₂Charging interval, such as it being decided to be 5 seconds, so when the people passes by, the people leaves in 5 seconds, electromagnetic valve just can not start, have only 5 seconds after capacitor C ₂The electric energy that is filled just is enough to make J ₂Must be electric, electromagnetic valve DF work.

Adjust R ₂, C ₂Value can set C ₂Discharge time, i.e. time of auto-flushing, C ₂Discharge off, then flushing stops automatically.The clothing footwear that drench the people for preventing to wash by water can be with J ₁Adopt time-delay relay, after the people left, the assurance relay J was cut off the power supply after 1 second, and corresponding solenoid valve is just opened water valve after the people leaves 1 second, wash by water.

For flush toilet, adopt following electromagnetic valve-quiet floatage control device 10(such as Fig. 3).

On the pull bar 12 of the former ball float 11 of water tank, load onto flexible chain 13, the other end of chain ties up on the former Draw off valve 14, lay down the needle-valve of feed tank water-filling, electromagnetic valve 15 is installed on its position, on the circuit that its coil and 220V power supply join, two switches 16,17,16 in parallel are for being Cheng Kaiguan, and 17 are infrared rays control contactor.Switch 16,17 can both independent control electromagnetic valve unlatching and closure.

After water had been put in the water tank, ball float 11 fell, and drove travel switch 16, opened electromagnetic valve and supplied water in water tank, and when water level rises to specified altitude, when ball float drove flexible chain and rises to tension, travel switch 16 closures stopped to supply water; After the people left for 1 second, on-off circuit was connected switch 17, and electromagnetic valve is water-filling in water tank, and along with water level raises, ball float 1 drives discharging valve 14 and opens, at this moment the electromagnetic valve auto-closing.

The utility model has the advantages that flush action all realizes automation. With the existing water closet of the utility model transformation, can overcome needle-valve and leak, the drawback such as discharging valve opener mechanical breakdown is many, using water wisely improves the serviceability rate of existing closet stall water filling system integral body greatly. Do not need people's switch water halter, avoid the infectious disease cross-infection that may occur. Water-saving result is remarkable, and this device can be set 5 seconds anti-interference not accepting with 8-15 and wash automatic stop second, and after the people leaves 1 second auto-flushing, avoid drenching people's clothing footwear. Compare with permanent current ability of swimming urinal, can economize on water more than 90%. Power consumption is low, correctly uses this device, and year power consumption is less than 1 degree; Compact conformation is loaded on the urinal or transforms existing water closet, realizes the bath automation.
