Abstract
A single chip microcomputer controlling device of contactless toilet differentiating flushing relates to a toilet water-saving device, in particular to a single chip microcomputer controlling device of contactless toilet differentiating flushing, which is characterized in that the utility model comprises two groups of photoelectric inducing devices which respectively consist of photoresistors and switch resistors; a switch resistor circuit is connected with a relay, the normally open contact of which is connected with the input end of a single chip microcomputer; the output end of the single chip computer is connected with the input ends of two groups of switch resistors with opposite polarities; the two groups of switch resistors with opposite polarities are interconnected with an electromagnetic valve coil; and the electromagnetic valve is arranged at the water outlet end at the bottom of a toilet water tank. The utility model has the advantages that the two groups of photoelectric inducing devices are respectively designated that stool flushing water amount is six liters and urine flushing water amount is three liters, which are at the choice of users. The utility model makes up the deficiencies of inconvenient use and cross infection in the toilet differentiating and flushing devices of the prior art that adopt contact key pressing control.
Description
Technical field
The utility model relates to a kind of water-saving device of closet, particularly a kind of contact base closet stepping flushing single chip machine control device of exempting from.
Background technology
The utility model is before the applying date, and prior art toilet stepping flushing single chip machine control device adopts contact by key control, has the defective of using inconvenient and cross-infection.
Summary of the invention
The purpose of this utility model provides a kind of contact base closet stepping flushing single chip machine control device of exempting from.
The technical scheme that its technical problem that solves the utility model adopts is: this device comprises the single-chip microcomputer imput output circuit; Its architectural feature is to have two groups of photoelectric induction devices, photoelectric induction device is connected to form by light resistor, switching tube and relay respectively, relay normally open contact one end links to each other with positive source, the other end is connected with the single-chip microcomputer input, the single-chip microcomputer output is connected with two groups of opposite polarity switching tube inputs, two groups of opposite polarity switching tubes are connected with electromagnetic valve coil, and electromagnetic valve is installed in toilet water tank bottom water side.
The beneficial effects of the utility model are that two groups of photoelectric induction devices are defined as 6 liters of stool baths respectively and urine is washed by water 3 liters, select for use for the user.Overcome prior art toilet stepping flushing single chip machine control device and adopted contact, had the defective of using inconvenient and cross-infection by key control.
Description of drawings
The utility model is described in further detail below by accompanying drawing.
Accompanying drawing 1 is an electrical schematic diagram of the present utility model.
The specific embodiment
Consult Fig. 1.Single-chip microcomputer is the PIC16C54 8-bit microcontroller of U.S. Microchip company among the figure.
This device comprises the single-chip microcomputer imput output circuit; Embodiment has two groups of photoelectric induction devices, photoelectric induction device is respectively by light resistor R1, R2, switching tube G1, G2 and relay J 1, J2 connects to form, relay J 1, J2 constant open contact one end links to each other with positive source (+), the other end and single-chip microcomputer PIC16C54 input I/O (1), I/O (2) is connected, single-chip microcomputer PIC16C54 output I/O (3), I/O (4), I/O (5), I/O (6) and two groups of opposite polarity switching tube G3, G4, G5, the G6 input is connected, two groups of opposite polarity switching tube G3, G4, G5, G6 is connected with electromagnetic valve D coil, and electromagnetic valve D is installed in toilet water tank bottom water side.
Two groups of photoelectric induction devices are defined as 6 liters of the stool baths and 3 liters of the baths of urinating respectively among the embodiment, select for use for the user.Single-chip microcomputer PIC16C54 is according to the difference of the optoelectronic induction voltage signal of switching tube G1, G2 output, and the electromagnetic valve D that control is installed in toilet water tank bottom water side opens and closes in limited time, realizes 6 liters or 3 liters of baths.Overcome prior art toilet stepping flushing single chip machine control device and adopted contact, had the defective of using inconvenient and cross-infection by key control.
