The water outlet holes are arranged at equal intervals.

The diameter range of the water outlet hole is 2-20 mm. Depending on the volume of the water treatment device, it is preferable that the diameter of the water outlet hole is 2.5mm when the diameter of the annular tube body is 430 mm.

The inlet tube has the following characteristics:

(1) one end of the pipe body is blocked and water is discharged through the smaller water outlet hole, so that the water is more uniform than water discharged from a direct pipe orifice;

(2) the water outlet holes are arranged at equal intervals, so that the water outlet is more uniform;

(3) when the annular pipe body is adopted, the water outlet hole faces to the circle, and in the lifting process of the inner barrel (namely the filter element), the water outlet can wash the outer wall of the inner barrel, so that the self-cleaning effect is achieved.
