the semi-finished product purified water flows radially to all directions around through each group of water inlet holes, and contacts with flocculating agents seeped out from through holes of the flocculating agent storage balls in each group respectively in the flowing process, so that harmful microorganisms in the semi-finished product purified water undergo flocculation reaction, and chemical purification is completed, so that finished product purified water is obtained;

the finished purified water flows out radially from each group of water outlet seepage holes under the pushing and extrusion of the subsequent water flow, and finally is discharged out of the water purifier shell.

The semi-finished product water purification is uniformly diffused in different directions in a radial way all the time in chemical purification, so that the water accumulation caused by unidirectional water drainage is avoided, and the water drainage speed is also increased.

Although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
