Abstract
The utility model discloses to a toilet bowl water-saving device without touching for train of motor train unit, which relates to a toilet bowl water-saving device, in particular to a toilet bowl photoelectric induction water-saving device without touching for train of motor train unit. The utility model is characterized in that two groups of photoelectric induction devices are provided. The photoelectric induction device consists of a photoconductive cell and a triode circuit, wherein, the triode circuit is connected with the input terminal of a singlechip; the output terminals of the singlechip are connected with the input terminals of two groups of switching tubes with opposite polarities; the output terminals of two groups of switching tubes with opposite polarities are connected with windings of solenoid valves, the solenoid valves are connected in series with two ends of the flush pipe of the toilet bowl; the output terminals of the singlechip are respectively connected with luminotrons. Two groups of the photoelectric induction devices are respectively defined as 6L stool flushing water and 3L piss flushing water, which are chosen by users. The utility model overcomes the defects that the single photoelectric induction device of the toilet bowl photoelectric flushing device for train of motor train unit can not differentiate stool and piss flushing water in the prior art, which is propitious to save water.
Description
Technical field
The utility model relates to a kind of water-saving device of closet, and particularly a kind of motor train unit train toilet optoelectronic induction exempts to contact water saving fixtures.
Background technique
The utility model is before the applying date, and the single photoelectric sensor of prior art motor train unit train toilet photoelectricity flushometer does not have the scarce filling of distinguishing the stool and urine bath, is unfavorable for using water wisely.
Summary of the invention
The purpose of this utility model provides a kind of motor train unit train toilet and exempts to contact water saving fixtures.
The technological scheme that its technical problem that solves the utility model adopts is: this device comprises the single-chip microcomputer imput output circuit; Its structure characteristic is to have two groups of photoelectric induction devices, photoelectric induction device is made up of photoresistor and transistor circuit, transistor circuit is connected with the single-chip microcomputer input end, the single-chip microcomputer output terminal is connected with two groups of opposite polarity switching tube input ends, two groups of opposite polarity switching tubes are connected with electromagnetic valve coil, and solenoid valve is serially connected in water-closet bowl flushing pipe two ends.The single-chip microcomputer output terminal is connected with luminotron tube respectively.
The beneficial effects of the utility model are that two groups of photoelectric induction devices are defined as 6 liters of stool baths respectively and urine is washed by water 3 liters, select for use for the user.Overcome the single photoelectric sensor of prior art motor train unit train toilet photoelectricity flushometer and do not had the scarce filling of distinguishing the stool and urine bath, helped using water wisely.
