When the waste water end of the reverse osmosis filter element 12 presses the pressure of the first valve port 141, the waste water pushes the diaphragm assembly 147 open through the second groove 1442 and flows into the third groove 1443, and the waste water in the third groove 1443 is discharged through the third valve port 143.
