At the same time, it can also ensure the fluidity of the surface of the water diversion plate 11, and avoid it being blocked by impurities, affecting the flow rate of sewage into the filter chamber 6 and affecting the filtering effect of sewage.

[0035] See Figure 6 、 Figure 7 、 Figure 8 and Figure 9 and Figure 10 The cleaning mechanism also includes a receiving groove opened at the bottom of the drain trough 29, and a water baffle 25 is slidably connected in the receiving groove.
