Abstract
The utility model discloses a kind of infrared-sensing type water closet control device that can distinguish the excrements auto-flushing, comprise that central processing unit (1), water tank auto-flushing control valve (2), infrared-sensing type receive and control circuit (3) switch executive circuit (4) and power supply (5); It is characterized in that: central processing unit (1) is a 8-bit microprocessor; Water tank auto-flushing control valve (2) is impulse electromagnetic valve or general solenoid valve, is installed on the water tank water side; The infrared-sensing type reception receives human body signal with control circuit (3) and is connected in the I/O input of central processing unit (1); Switch executive circuit (4) connects impulse electromagnetic valve by the switching tube drive circuit, and power supply (5) is Dc low voltage power supply or passes through the dc source that the rectification of civil power transformation produces.Belong to the singlechip technology field, particularly single-chip microcomputer infrared-sensing type control technology is applicable to that all kinds of water closets are distinguished excrements to be washed automatically.The utility model can be realized by 6 liters of international standard stool baths, 3 liters of flushings automatically of urine bath, need not manual intervention, solve traditional water closet and can not distinguish the problem that excrements is washed by water and radiator leak causes waste water resource and can not guarantee promptly to dash after an action of the bowels, its intelligent degree height, water-saving result is obvious, also favourable maintenance sanitation of environment and prevent cross-infection.
Description
Technical field the utility model belongs to microchip technology field, particularly single-chip microcomputer infrared-sensing type control technology.
Before background technology the utility model applying date, 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 summary of the invention the purpose of this utility model is exactly that a kind of infrared-sensing type water closet control device that can distinguish the excrements auto-flushing will be provided.
The technical scheme that its technical problem that solves the utility model adopts is: comprise that central processing unit (1), water tank auto-flushing control valve (2), infrared-sensing type receive and control circuit (3) switch executive circuit (4) and power supply (5); Central processing unit (1) is a 8-bit microprocessor; Water tank auto-flushing control valve (2) is impulse electromagnetic valve or general solenoid valve, is installed on the water tank water side; The infrared-sensing type reception receives human body signal with control circuit (3) and is connected in the I/O input of central processing unit (1); Switch executive circuit (4) connects impulse electromagnetic valve by the switching tube drive circuit, and power supply (5) is Dc low voltage power supply or passes through the dc source that the rectification of civil power transformation produces.Impulse electromagnetic valve is controlled by the pulse forward or backwards of two I/O output ports of central processing unit (1), and the electromagnetic valve coil two ends link to each other with the colelctor electrode of a pair of opposite polarity silicone tube and germanium tube respectively.
The beneficial effects of the utility model are: adopt single auto-flushing 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.
