The interior of the evaporator fan body 1 has a basic air filtering structure, and a filter plate 16 is added to the air outlet pipe 2. When the air filtering structure in the evaporator fan body 1 is damaged or needs to be cleaned, the filter plate 16 can replace the air filtering structure in the evaporator fan body 1 to filter the air, so that the evaporator fan body 1 can filter the air well. When the filter plate 16 needs to be cleaned, loosen the screws at the second docking plate 5, remove the air guide pipe 4, and then remove the filter plate 16. The structure is simple and easy to operate;

[0024] The air guide 4 is similar to the arm of a desk lamp and can be bent at multiple angles. The length of the air guide 4 is not mandatory here, so that the air outlet ring 9 can be adjusted at multiple angles, the air outlet direction can be adjusted in a wide range, and the limitation during use is low;
