Abstract
The present invention discloses automatic flushing infrared inducing closet controller capable of distinguishing shit and urine for automatic flushing and relates to monichip computer application and infrared control technology. The main characteristic is to install flushing solenoid valve installed in the outlet of the cistern and controlled by the CPU and to provide with infrared inducing signal receiving and amplifying circuit, monochip control circuit and switch executing circuit connected successively. The present invention flushes automatically in the water amount of 6 L for shit and 3 L for urine and can save water and keep clean.
Description
Technical field patent of the present invention belongs to microchip technology field, particularly single-chip microcomputer infrared-sensing type control technology.
Background technology patent application of the present invention a few days ago, the utility model patent 02256516.7 of having authorized except that me " can be distinguished the excrements saving toilet of flushing automatically " and adopt automatic loading water electromagnetic valve and the auto-flushing electromagnetic valve, does not have saving toilet and infrared-sensing type control device that single employing automatic flushing valve can be distinguished the excrements auto-flushing.The while radiator leak.
The purpose of summary of the invention patent of the present invention is exactly to provide the single employing auto-flushing of a kind of energy electromagnetic valve to distinguish the infrared-sensing type water closet control device of excrements auto-flushing, be applicable to that all kinds of water closets are distinguished excrements to be washed automatically, has both helped the conserve water resource and has also helped keeping sanitation of environment and preventing cross-infection.Solve the problem of radiator leak simultaneously.
Description of drawings Fig. 1 is the circuit structure block diagram of patent of the present invention.Wherein 1 is central processing unit, and 2 is water tank auto-flushing control valve, and 3 for infrared-sensing type receives and control circuit, and 4 is the switch executive circuit, and 5 is power supply.
