[0038] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a filtering mechanism 8, which includes a water diversion pipe 81, a water pump 82, a second support frame 83, a filter box 84, a box cover 85, a drain pipe 86, a second support plate 87, a filter screen 88, a partition 89 and a sterilization lamp 810.
