Abstract
The utility model discloses a contact-free water saving device for a closestool of a motor train set and relates to a closestool water saving device; the closestool water saving device is characterized in that two groups of field-effect tube voltage induction devices are provided and the field-effect tube voltage induction devices consist of field-effect tubes and switching tube circuits. A drain electrode of the field-effect tube is connected with a non-inverting input end of an integrated transfer circuit. An output end of a switching tube is connected with relay coils and one end of a normally open contact of a relay is connected with a positive electrode of a power supply. The other end of the normally open contact of the relay is connected with an input end of a single-chip microcomputer. Output ends of the single-chip microcomputer are respectively connected with input ends of two groups of switching tubes with opposite polarities. The two groups of switching tubes with opposite polarities are connected with electromagnetical valve coils and an electromagnetical valve is connected in series at both ends of a flush pipe of the closestool. The closestool water saving device has the advantages that the two groups of field-effect tube voltage induction devices are respectively defined as stool flushing of 6 L and urination flushing of 3 L which are provided for users to choose. Furthermore, the closestool water saving device of the utility model overcomes the defects that a closestool of a motor train set in the prior art can not differentiate the stool flushing from the urination flushing. Therefore, the closestool water saving device is favorable to saving 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 FET voltage induced exempts to contact water saving fixtures.
Background technology
The utility model is before the applying date, and the scarce filling that excrements is washed by water is distinguished in not having of prior art motor train unit train water-closet bowl flushing apparatus, 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 technical scheme that its technical problem that solves the utility model adopts is: this device comprises the single-chip microcomputer imput output circuit; It is characterized in that having two groups of FET voltage induced devices, FET voltage induced device is made up of FET and switching tube circuit, the drain electrode of FET is connected with the in-phase input end of amplifier integrated circuit, the switching tube output is connected with relay coil, one end of relay normally open contact is connected with positive source, the other end of relay normally open contact is connected with the single-chip microcomputer input, the single-chip microcomputer output is connected with two groups of opposite polarity switching tube inputs respectively, two groups of opposite polarity switching tubes are connected with electromagnetic valve coil, and electromagnetic valve is serially connected in water-closet bowl flushing pipe two ends.
The beneficial effects of the utility model are that two groups of FET voltage induced 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 prior art motor train unit train toilet and do not had the scarce filling of distinguishing the excrements bath, helped using water wisely.
Description of drawings
The utility model is described in further detail below by accompanying drawing.
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
The specific embodiment
Consult Fig. 1.Single-chip microcomputer is the PIC16C54 8-bit microcontroller of U.S. Microchip company among the figure.
Two groups of FET voltage induced devices are respectively by FET 3DJ6-1,3DJ6-2 and switching tube G1, G2 forms, FET 3DJ6-1, the drain electrode of 3DJ6-2 respectively with switching tube G1, the G2 input is connected, switching tube G1, the G2 output respectively with relay J 1, the J2 coil is connected, relay J 1, one end of J2 constant open contact is connected with positive source (+) respectively, relay J 1, the other end of J2 constant open contact respectively with single-chip microcomputer PIC16C54 input I/O (1), I/O (2) is connected, single-chip microcomputer PIC16C54 output I/O (3), I/O (4), I/O (5), I/O (6) respectively with two groups of opposite polarity switching tube G3, G4, G5, the G6 input is connected, two groups of opposite polarity switching tube G3, G4, G5, G6 is connected with electromagnetic valve coil L, and electromagnetic valve is serially connected in water-closet bowl flushing pipe two ends.
Single-chip microcomputer is according to the output level of two groups of FET voltage induced devices, and control electromagnetic valve reaches water-saving purpose by 3 liters of 6 liters of baths and the urine baths of defecating.
