After the purification assembly is saturated, the cleaning assembly can clean and collect the impurities accumulated on the surface of the filter element without disassembly and replacement. After the activated carbon is saturated, the impurities in the activated carbon are quickly discharged through heating and thermal expansion and contraction. Then the impurities are quickly discharged by water flow. Similarly, disassembly and replacement are not required, which greatly reduces the maintenance frequency, thereby avoiding the problem that the replacement process is troublesome. The water vapor generated by the spraying chamber 2 is recycled by the circulating assembly and then enters the spraying chamber 2 again, thereby achieving recycling and saving water resources.
