[0027] The interior of the filter box 10 is filled with potassium permanganate particles, a filter cover 11 is arranged between the inner walls of the filter box 10 near one side edge, a perspective ring 4 is arranged on the side wall of the docking sleeve 3, and the filter box 10 is located on the inner side of the perspective ring 4;
[0028] First, the air inlet pipe 1 is connected to the air outlet end of the external controlled atmosphere preservation device, and then the air outlet pipe 5 is connected to the air inlet end of the external controlled atmosphere preservation device, so that the air containing ethylene inside the controlled atmosphere preservation device can be circulated through the air inlet pipe 1 into the interior of the docking sleeve 3 to remove the ethylene and then flow into the interior of the controlled atmosphere preservation device through the air outlet pipe 5, thereby realizing the circulation of gas and removing the ethylene at the same time.
[0029] Furthermore, a gasket ring 13 is fixed between the inner walls of the docking sleeve 3 near one edge, and one side of the filter box 10 and one side of the gasket ring 13 are fitted together. By providing the gasket ring 13, a gap can be left between one side of the conical recessed surface of the filter box 10 and one side of the docking plate 12 to facilitate air circulation and support the filter box 10 at the same time.
