Abstract
The utility model relates to a washing apparatus for urinals which is a device utilizing infrared ray sensing technology to control a water saving valve to automatically wash the urinal. When people enters into a prearranged area, infrared emitted by an infrared emitter is received by an infrared sensor after reflected by the human body, and signals treated by amplification, filtering, shaping, etc. change into a wait state from a static state. When people leaves the prearranged area, the utility model works and the contacts of a breaker close; an electromagnetic valve presses the water saving valve to wash the urinal. After the washing apparatus completes washing and press, the static state is restored.
Description
The utility model relates to a kind of device that uses the automatic flush urinal of infrared ray sensing technology control water-saving valve.
Public lavatory urinal automatic flushing device flowing water is continuous at present, wastes water, and the urinal of dress water-saving valve also has cross-infection.
Order of the present utility model is to use the automatic flush urinal of infrared ray sensing technology control water-saving valve, overcomes above-mentioned prior art weak point.
The purpose of this utility model realizes by following design scheme, 74LS14IC1 pin one～6 connect capacitor C 7 in the control circuit, resistance R 8, R6, R5, triode BG1, RF transmitter LED launches infrared rays, pin 8～13 connects electric capacity, diode, resistance, triode, control relay (J,) the CX20106AIC2 pin connects electric capacity, resistance, infrared ray sensor PH302, receive the infrared rays of human body reflection, the 220V power supply is after transformer B1 transformation, the output shunt capacitance C8 of full-wave rectification, meet stabilizator 7805IC3, output+5V working power; The electromagnetic valve of mechanical actuating mechanism (3) is contained in the central authorities of base plate (1), left side dress transformer (2), the right device, circuit board (4), base plate (1) are gone up dress case (5), the place ahead dress RF transmitter (6) and the infrared ray sensor PH302(7 of case).
In conjunction with the accompanying drawings embodiment of the present utility model is elaborated, Fig. 1 is a urinal syringe structure chart, the electromagnetic valve of mechanical actuating mechanism (3) is contained in the central authorities of base plate (1), left side dress transformer (2), the right device, circuit board (4), base plate (1) is gone up dress case (5), the place ahead dress RF transmitter LED(6 of case) and infrared ray sensor PH302(7).
Fig. 2 is the control circuit schematic diagram, and Fig. 3 is a workflow diagram, and 74LS14IC1, pin two, 3 are connected and pin one parallel resistance R8 in the control circuit, connect capacitor C 7 again, ground connection again, pin 5,4 is connected, and pin 6 connecting resistance R6 join with triode BG1 base stage again, grounded emitter, pin 7 connects+5V and RF transmitter LED, connecting resistance R5 again, and resistance R 5 other ends and colelctor electrode join, pin 8 connects capacitor C 4, and pin 9,10 meets diode D1; Pin one 0 connecting resistance R7, resistance R 7 shunt capacitance C5, pin one 1 connects capacitor C 6, capacitor C 6 other ends and resistance R 7 ground connection again of joining, pin one 2 meets diode D2, and pin one 3 meets diode D3, the positive pole of diode D2, D3 and resistance R 9 connect the base stage of triode BG2 simultaneously, the grounded emitter of triode BG2, collector connecting relay J, resistance R 9 other ends and+5V succeeds the other end of electrical equipment.The pin one of CX20106AIC2 meets infrared ray sensor PH302, pin two meets capacitor C 1, R1, pin 3 connects capacitor C 2, pin 6 connects capacitor C 3, PH302, the other end of resistance R 1, capacitor C 2, C3 and pin 4 equal ground connection, pin 5 connecting resistance R2, R3, pin 7 connects capacitor C 4, resistance R 4, and resistance R 3, R4 and pin 8 connect+5V; Supply voltage is paid the limit through full-wave rectification after transformation, shunt capacitance C8 again, and capacitor C 8 positive poles connect stabilizator 7805IC3, minus earth.
The utility model is work like this, in the time of in the people enters presumptive area, infrared transmitter LED(5) Fa She infrared rays, reflex to infrared ray sensor PH302(8 through human body), through amplifying, filtering, signals such as shaping are handled, make flushing device for toilet transfer wait state to, treat that the people leaves presumptive area, blackout by inactive state, triode BG2 drives relay (9) work, make the constant open contact closure, electromagnetic valve is by adhesive, and electromagnetic valve presses water-saving valve switch (11) urinal is washed, through monostable circuit time-delay in 1 second, the relay outage, electromagnetic valve resets, and finishes the flushing action.Wait for next flushing action.
The utility model has the advantages that automatic bath, water saving prevents cross-infection, improves health level.
