Description of drawings

Below by accompanying drawing, the utility model will be further described.

Accompanying drawing 1 is the electrical schematic diagram of the utility model.

Detailed ways

See Figure 1. The single-chip microcomputer in the picture is PIC16C54 eight-bit single-chip microcomputer of American Microchip Company.

This device comprises single-chip microcomputer input and output circuit; Embodiment has two groups of photoelectric induction devices, and photoelectric induction device is made up of photosensitive resistance R1, R2 and switching tube G1, G2 respectively, switching tube G1, G2 circuit and single-chip microcomputer PIC16C54 input terminal I/O ( 1), I/O (2) are connected, and the output terminals I/O (3), I/O (4), I/O (5), and I/O (6) of the single-chip microcomputer PIC16C54 are opposite to the two groups of polarities The input ends of the switch tubes G3, G4, G5, and G6 are connected, and two sets of switch tubes G3, G4, G5, and G6 with opposite polarities are connected with the solenoid valve D coil, and the solenoid valve D is installed at the water outlet at the bottom of the toilet tank.

In the embodiment, two groups of photoelectric sensing devices are respectively defined as 6 liters of stool flushing water and 3 liters of urine flushing water for users to choose. The single-chip microcomputer PIC16C54 controls the opening and closing of the electromagnetic valve D installed at the water outlet end of the bottom of the toilet tank according to the difference of the photoelectric induction voltage signal output by the switch tube G1 and G2, and realizes flushing of 6 liters or 3 liters. The utility model overcomes the disadvantages of inconvenient use and cross-infection that exist in the prior art that the single-chip microcomputer control device for flushing of toilets adopts touch-type buttons.
