CN201028098Y - Non-contact water-saving device of motor train unit closet - Google Patents

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 field effect transistor voltage induction water-saving device without touching for train of motor train unit. The utility model is characterized in that two groups of field effect transistor voltage induction devices are provided. The field effect transistor voltage induction device consists of a field effect transistor and a switching tube circuit; wherein; the switching tube 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. Two groups of the field effect transistor voltage 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; thereby, the utility model is propitious to save water.
