[0023] Specifically, the filter plate 501 inside the filter box 5 is an activated carbon sieve plate, and a plurality of through holes can be provided on the surface, so that larger solid particles and waste residues in the raw water can be filtered for the first time. The output end of the motor 2 passes through the top of the purification chamber 1 and is fixedly connected to two connection plates 12, and one of the connection plates 12 is located at the top of the ultrafiltration membrane core 16, and the other is located at the bottom of the ultrafiltration membrane core 16.
