The beneficial effect of the utility model is that two groups of field effect tube induction devices are respectively defined as 6 liters of flushing water for stool and 3 liters of flushing water for urination, for users to choose. The utility model overcomes the disadvantages of inconvenient use and cross-infection that exist in the prior art that the flushing device of the toilet is controlled by touch buttons.

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.

The device includes a single-chip microcomputer input and output circuit; the embodiment has two sets of field effect tube sensing devices, the field effect tube sensing devices are respectively composed of field effect tubes 3DJ6-1, 3DJ6-1 and switch tubes G1, G2, switch tubes G1, G2 circuit It is connected with the input terminal I/O(1) and I/O(2) of the single-chip microcomputer PIC16C54, and the output terminal I/O(3), I/O(4), I/O(5) and I/O( 6) Connect with the input terminals of two sets of switching tubes G3, G4, G5, and G6 with opposite polarities. The two sets of switching tubes G3, G4, G5, and G6 with opposite polarities are connected with the solenoid valve D coil. At the outlet end of the bottom of the toilet tank.

In the embodiment, two sets of FET 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 in the voltage signal of the field effect tube 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 step-by-step flushing device of the toilet is controlled by touch buttons.
