[0038] As a technical optimization solution of the utility model, the operator moves the rectangular block 19, and then the rectangular block 19 causes the baffle 18 to rotate.

[0039] The working principle and use process of this utility model:

[0040] When the operator needs to inspect the fresh air fan body 1 and remove the inspection plate 2, he first pulls the pulling plate 7. The pulling plate 7 will carry the card plate 6 to move toward each other under the cooperation of the long plate 4 and the movable block 5. At this time, the card plate 6 will apply an extrusion force to the spring 9 and leave the inside of the rectangular plate 3. At this time, the fixing effect of the rectangular plate 3 will be released. At this time, the operator moves the inspection plate 2 downward. At this time, the inspection plate 2 will quickly leave the bottom of the fresh air fan body 1, and the inspection plate 2 can be quickly removed.

[0041] When the operator needs to clean the dust blocked by the filter hole 15, the rectangular block 19 is moved, and the rectangular block 19 will rotate with the baffle 18. At this time, the baffle 18 will leave the front of the filter plate 14 and release the blocking effect on the filter plate 14. At this time, the operator pulls the pull plate 16, and the pull plate 16 will move the filter plate 14 forward under the limit of the limit plate 12 and the connecting block 13. At this time, the operator can clean the dust inside the filter hole 15.
