Working principle of example 1:

when the flushing is needed, the handle 284 is rotated to drive the rotating shaft 23 to rotate, the coil spring 293 is stretched, the rotating shaft 23 drives the second ceramic piece 272 to rotate, due to the matching of the clamping block 285 and the clamping groove 2831, the rotating range of the rotating shaft 23 is limited, when the rotating shaft 23 rotates to the maximum range, the first through groove 2721 and the second through groove 2722 respectively cover the two through holes 275 of the first ceramic piece 271, when the first connecting pipe 24, the second connecting pipe 25 and the pressure relief pipe 26 are in a communicated state, the air pressure of the hose 3 and the circular inner cavity 22 is smaller than the water pressure of the water inlet pipe 11 of the direct flushing valve 1, and water flow can enter the first water outlet pipe 12 and the second water outlet pipe 13 from the water inlet pipe 11 and is discharged from the first water outlet pipe 12 and the second water outlet pipe 13 for flushing;

when the water way is required to be closed after the flushing is finished, the handle 284 is loosened, the coil spring 293 returns to the original length to drive the rotating shaft 23 to reversely rotate and drive the second ceramic piece 272 to rotate, when the second ceramic piece 272 reversely rotates to the maximum range, the first through groove 2721 and the second through groove 2722 do not cover the two through holes 275 of the first ceramic piece 271, the first connecting pipe 24, the second connecting pipe 25 and the pressure relief pipe 26 are in an unconnected state, the air pressure of the hose 3 and the circular inner cavity 22 is greater than the water pressure of the water inlet pipe 11 of the direct flushing valve 1, the water flow is prevented from entering the first water outlet pipe 12 and the second water outlet pipe 13, and the closing of the water way is realized.

Example 2:

referring to fig. 7, it is different from embodiment 1 in that: the centers of the first through groove 2721 and the second through groove 2722 are symmetrically distributed, and the radian of the first through groove 2721 is greater than that of the second through groove 2722.

Working principle of example 2:

when the second ceramic sheet 272 rotates and the second through groove 2722 is separated from covering one through hole 275, the first through groove 2721 also covers the other through hole 275, so that one of the first connecting pipe 24 and the second connecting pipe 25 is communicated with the pressure relief pipe 26, one of the second connecting pipe 25 and the first connecting pipe 24 is not communicated with the pressure relief pipe 26, and therefore one of the first water outlet pipe 12 and the second water outlet pipe 13 is closed first, and the other one is delayed to be closed.
