Abstract
The utility model discloses an automatic flushing device of a pulse electromagnetic valve type for a crouching toilet in a train based on infrared induction, which comprises an infrared induction device, a control circuit of a single chip computer and a control circuit of a pulse electromagnetic valve. The utility model is characterized in that an I/O input terminal of a single chip computer is connected with a pulse signal output terminal of the infrared induction device; an I/O output terminal of the single chip computer is connected with a control device of the pulse electromagnetic valve, wherein the pulse electromagnetic valve is in series connected between water supply pipes of a train. Based on the technology of infrared induction, urination and defecation are differentiated through human body induction time, and a flushing device of a key type or a foot pedal type of an original crouching toilet on the train is replaced by automatic water flushing in the mode that defecation is flushed with 6 liters of water and urination is flushed with 3.5 liters of water. The utility model has the advantages that water resource can be saved, and is favorable for the toilet use environment of the train. The utility model is suitable for the control of a new generation of squatting toilets in trains.
Description
Technical field the invention belongs to the application of single-chip microcomputer in the sanitary equipment technology.
Before background technology the invention, known train squat toilet adopts foot-operated or the key mode bath is washed by water owing to not distinguishing stool and urine, causes the waste of train limited water resources, as untimely flushing, causes pollution and the cross-infection of train with the lavatory environment.
The purpose of summary of the invention the invention is intended to overcome the defective of prior art, and a kind of train squat toilet pulse magnetic valve automatic flushing device based on infrared induction is provided.
The invention solves the technical scheme that its technical matters adopts: comprise infrared inductor, single chip machine controlling circuit and pulse electromagnetic valve controling circuit, the I/O input end of single-chip microcomputer is connected with the pulse signal output end of infrared inductor, the I/O output terminal of single-chip microcomputer is connected with the pulse electromagnetic control valve device, infrared inductor is made up of infrared reception and power valve, hex inverter and phaselocked loop, finish infrared emission, reception, modulation and demodulation, the output terminal of phaselocked loop is connected with the single-chip processor i/o input end.Impulse electromagnetic valve is serially connected with between the train supply channel.Single-chip microcomputer is according to the time of secondary useful signal, and judgement stool and urine is used the lavatory state, and then the switching time of gating pulse solenoid valve, just needing by size to realize auto-flushing.Pulse electromagnetic valve coil L is connected with a pair of positive-negative-positive triode and a pair of NPN type triode respectively, four triodes are connected with the single-chip processor i/o output terminal respectively, the polarity of the output pulse by changing single-chip microcomputer changes the direction of current that flows through the pulse electromagnetic valve coil, thus the switching of driving pulse solenoid valve.Impulse electromagnetic valve is serially connected with between the train feed pipe.
The beneficial effect of the invention is: the invention is based on the infrared induction technology, time length by human body sensing is distinguished stool and urine, and replace former train squatting pan button bath or ride flushometer by 6 liters in stool, 3.5 liters of auto-flushings of urine, the beneficial effect of the invention be the conserve water resource also help train use the lavatory environment, be widely used in the control of train a new generation squatting pan.
