[0023] Specifically, extension pipes 8 are fixedly arranged at both ends of the filter tube 7, and the two extension pipes 8 are respectively fixedly connected to the water inlet valve 2 and the water supply pipe 4. A filter net 9 is arranged inside the filter tube 7, and one end of the filter net 9 is connected to the extension pipe 8 close to the water supply pipe 4, and the other end of the filter net 9 is fixedly provided with an end plate 10.
