Abstract

A water purifier switch valve provides a valve base with an upper water inlet hole, a lower water outlet hole, a purified water hole, and a waste water hole. Gap between each hole in the valve base is provided with a spherical space which is pivoted with a spherical flow divider provided with three groups of separate and non-communicated holding room. In cooperation of the rotated spherical flow divider localizing in three steps, the three groups of separate and non-communicated holding room have filtrated water used state, back washing waste water discharged state, and testing purified water discharged state, respectively. In addition, matching to the corresponding mount between the spherical space and the spherical flow divider, the waster water will not flow into the purified water hole in back washing state. Despite the raised water flow stability owing to the great enlargement of the pore path and of the volume of each channel in the holding room, the utility model also has the advantages of high pressure resistance, unhindered rotation, and indestructibility.
