Abstract
The utility model relates to an intelligent automatic flush water-saving device which detects excrements inside a urinal through a strain gage type pressure sensor. When excrements is excreted into the urinal, pressure is generated and the resistance of the pressure sensor changes correspondingly; meanwhile, bridge output voltage is amplified to drive a servomotor to work so as to control the switch of a flush pipe valve through a retarding mechanism and a drive mechanism for flushing the urinal. The utility model which adopts intelligent automatic control to realize optimum control of flushing volume can save a great amount of precious water resource and also brings great convenience and comfort to daily life.
Description
The utility model belongs to intelligent automatic flushing water saver.
What generally adopt in most of public lavatories at present, is bath devices such as hand pulling type and timing.The common shortcoming of this class bath device is: cause the great amount of water resources waste, and can not in time wash away the ight soil in the urinal fast, stay niff, can't keep the cleaning in lavatory.Hand pulling type bath device wherein commonly used also needs to remove to draw back flush valve with hand, and this had been both unhygienic also makes troubles to the user, thus the sight that often has the ight soil in the urinal not wash away.
The purpose of this utility model provide a kind of can be in time quick, with the intelligent automatic flushing water saver of optimal dose water auto-flushing.
The purpose of this utility model is achieved in that intelligent flushing water saver is made up of strain gauge pressure sensor, drive circuit, DC servo-motor, reducing gear, transmission mechanism, valve and other parts.Wherein resistance-strain chip pressure sensor adopts ceramic-type the best, is placed in the bottom of urinal.Drive circuit is integrated by the elements such as electric bridge, operational amplifier and resistance of band slide rheostat.Wherein in order to eliminate the influence of temperature to bridge output voltage, electric bridge adopts the electric bridge penalty method, and promptly a temperature-compensating foil gauge identical with the foil gauge material of pressure sensor is settled in position that can pressurized in urinal.The output of reducing gear is connected on the slide head of slide rheostat of valve and electric bridge.Valve adopts the bottom to have the circular steel disc of suitable thickness rubber pad, and the diameter of this valve is more bigger than the outer bore of jet water spout.The one sutaining valve door track frame consistent with the valve swing-around trajectory that have a down dip arranged at the top of jet water spout.Wherein other water-storing devices in the water storage box are identical with the device of present common use.
When in the urinal during no excrements, electric bridge is in equilibrium state, and output voltage is zero, and motor does not change.When in the urinal excrements being arranged, the strain gauge pressure sensor that is positioned at the urinal bottom will be sensed pressure, reaction increases for foil gauge resistance, make the electric bridge disequilibrium, electric bridge output positive voltage, after amplifying, amplifier is added on the DC servo-motor, motor is rotated in the forward, the changeover valve that drives jet water spout by reducing gear rotates, open valve begin to discharge water ight soil in the flushing toilet bowl, this moment, urinal was interior owing to go into the increase of the water yield, quickened and make bridge output voltage increase, motor rotate.Simultaneously reducing gear drives also that the slide rheostat slippery fellow moves to the direction that resistance reduces in the electric bridge, makes electric bridge reach new balance in the process of bath, and bridge output voltage is zero during balance, the motor stall.When the ight soil in the urinal is poured sewer suddenly, sensor sensing changes to bigger pressure, make foil gauge resistance reduce rapidly, the electric bridge of new balance is disequilibrium again, and the negative voltage that electric bridge output is higher is added on the motor after amplifier amplifies, the drive motor reverse rotation, the changeover valve that drives outlet pipe by reducing gear turns round, and gets back to initial position up to valve, valve-off.Because the steel disc valve is flexible and rubber pad is arranged at its bottom, valve is just better fastened valve under the pressure of water in water tank like this, prevents to leak.At this moment, do not had ight soil and flowing water in the urinal, the bottom has not had pressure, and foil gauge returns to initial state, and resistance is reduced to initial value.Simultaneously, the slippery fellow of the slide rheostat in the electric bridge also gets back to initial position under the reverse drive of reducing gear, and electric bridge recovers the initial balance attitude, and output voltage is zero, the motor stall.
The advantage of the intelligent automatic flushing water saver of the utility model is: adopt intelligent automatic control, can reach the optimum control of discharging quantity of water, save great lot of water resources, again the ight soil in the flushing toilet bowl quickly, eliminate bad smell rapidly, keep the lavatory sanitation and hygiene.Adopt automatic control bath device also to bring great convenience simultaneously, need not remove to draw the valve of jet water spout again with hand to the user.Material of the present utility model is common, and cost is also relatively low, can give human a large amount of precious water resource of saving, and brings great convenience to people's life.
