The outer surface of the first flow guiding part 13 extends towards the direction far away from the anode plate 5, and preferably, the outer surface of the first flow guiding part 13 is a gentle slope, so that the speed of water flow flowing through the gentle slope can be reduced, and water drop splashing caused by over-fast water flow is avoided. The inner edge of the first flow guide piece 13 is tightly attached to the outer surface of the anode plate 5, so that water flow is prevented from flowing down from a gap between the first flow guide piece and the anode plate.
