The improved structure of the baffle of the decontamination box comprises a box portion and a baffle plate, and the box portion is formed by a box type with a bottom hole on the bottom surface and a plurality of bottom holes which can be loaded or not loaded as needed. Forming, the baffle is obliquely disposed in the inner space of the box portion, and the baffle has a neatly arranged flow guiding fin to form a perforated hole, and is matched with the upper half of the guiding fin The back side of the lower half has a structural feature with a bevel at an appropriate angle, and a cross baffle is provided under the curved baffle to prevent the water flow from sliding down the baffle below without directly dripping, when used, When dirt such as excrement, residual feed, and impurities flow through the surface of the deflector, the upper surface of the deflector fin may be blocked by the inclined surface of the deflector fin, and separated from the part of the water flow. The water does not fall through the interval through the through hole and is discharged from the bottom hole, and the dirt is discharged along the bottom plate by the remaining water flow, and then discharged by a drain hole. Discharged quickly, thus solving the problem of the decontamination structure of the practitioner can not effectively eliminate the excretion , residual feed, impurities and other problems caused by inconvenient water quality, and effectively achieve the advantages of structural simplification, but good quality and other functions, and can be systematically used together with other decontamination structures as needed, can be achieved Providing a convenient, efficient, adaptable and practically high decontamination box of the baffle to improve the structural structure and complete the functional requirements.一種除汙盒之導流板改良結構，包括有盒部，與導流板所組成，該盒部係以底部面開有視需要活動式可裝上或不裝之複數底部孔洞之盒體型態成型，該導流板係斜設於該盒部內空間處，並藉由該導流板具有整齊排列的導流鰭片組成間隔透孔的設計，搭配該導流鰭片之上半部與下半部背面各具適當角度頃斜面的結構特徵，以及該弧形導流板下方加有之橫隔板避免水流由下方順著該導流板下滑而不
