Abstract

The utility model relates to a double-acting washing apparatus for toilets which is a device utilizing infrared ray sensing technology to control a water saving valve to automatically wash the toilet. When a human body 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 amplifying, filtering, shaping, etc. change into a wait state from a static state. When a human leaves the prearranged area, an electric machine is driven by BG2 and a dialing slice rotates following the electric machine and leaves the integrated block UGS3020 of a Hall switch; a press plate is simultaneously toggled and the water-saving valve is opened to wash the toilet. The dialing slice rotates 180 DEG and the other end of the dialing slice is pressed on the integrated block UGS3020 of a Hall switch; the electric machine stops rotating and restores to the state after completing washing, waiting for next washing actions. During power failure, a hand button can be pressed with hands to carry out washing for the toilet after easing nature.

Description

Washing apparatus for toilet

The utility model relates to a kind of utilization infrared ray sensing technology control water-saving valve and wash closet stall automatically, a kind of device that by hand push button closet stall is washed when having a power failure.

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.

The purpose of this utility model is to use infrared ray sensing technology control water-saving valve to wash closet stall automatically, overcomes above-mentioned prior art weak point.

The purpose of this utility model realizes by following design scheme, 74LS14IC2 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, Hall switch integrated package UGS3020 controls motor, the CX20106AIC2 pin connects electric capacity, resistance, infrared ray sensor PH302 receives 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 motor reducer of mechanical actuating mechanism (10) is gone up fixedly plectrum (12), and plectrum disengagement Hall switch (11) is stirred pressing plate (8) when motor reducer (10) is worked, the water-saving valve flushing closet stall that discharges water.

In conjunction with the accompanying drawings embodiment of the present utility model is elaborated, Fig. 1 is two moving closet stall syringe structure charts, Fig. 2 is that the A of Fig. 1 is to view, motor reducer (10) is gone up fixedly plectrum (12), plectrum lower end and Hall switch integrated package UGS3020(11) contact, the plectrum left is the lower end of pressing plate (8), the pressing plate upper end is contained on the water-saving valve button (7), also adorn hand push button (6) on the water-saving valve button, water-saving valve (13) is contained on the base plate (1), adorn case (2) on the base plate, control circuit board (4) and transformer B1(3) be contained in the case RF transmitter LED(5) and infrared ray sensor (9) be contained on the case.

Fig. 3 is the control circuit schematic diagram, and Fig. 4 is a workflow diagram, and 74LS14IC1, pin two, 3 are connected and pin i parallel resistance R8 in the control circuit, connect capacitor C 7 again, ground connection again, pin 5.4 is connected, pin 6 connecting resistance R6 join with triode BG1 base stage again, grounded emitter, pin 7 connect+5V and RF transmitter LED, connecting resistance R5 again, resistance R 5 other ends and colelctor electrode join, and pin 8 connects capacitor C 4, and

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, and pin one 2 meets diode D2, 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, and colelctor electrode connects motor, resistance R 9 other ends and+5V is connected on the other end of motor, Hall switch integrated package UGS3020 and motor parallel.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, 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(9 through human body), through amplifying, filtering, signals such as shaping are handled, make flushing device for toilet transfer wait state to by inactive state, treat that the people leaves presumptive area, blackout, triode BG2 drive motors reducer (10) running, Hall switch (11) is thrown off in plectrum (12) lower end, the plectrum inhour is rotated, stir pressing plate (8), pressing plate is pressed water-saving valve button (7), and closet stall is washed, through monostable circuit time-delay in 1 second, the upper end turnback of plectrum contacts with Hall switch, and motor reducer stops operating, and finishes the flushing action.Wait for next flushing action.When having a power failure, with the moving button (6) of hand over hand, closet stall is washed after an action of the bowels.

The utility model has the advantages that automatic bath, water saving prevents cross-infection, improves health level.
