[0050] A plurality of fifth movable grooves 128 are provided on the side wall of the third movable groove 114, and the position of the fifth movable groove 128 corresponds to the second fixed block 113. A sixth movable groove is provided on the baffle plate, and a block 116 is provided in the sixth movable groove. The block 116 is provided with a third spring 126 and a first oblique groove, and one end of the third spring 126 is connected to the inner wall of the sixth movable groove; a third groove is provided on the mounting block 105, and a connecting plate 129 is provided in the third groove, and the third baffle 115 is slidably connected to the connecting plate 129; a second oblique groove 1271 is provided at one end of the second groove 127; a fourth groove is provided on the inner wall of the third groove, and a fourth spring 130 is provided in the fourth groove, and one end of the fourth spring 130 is fixedly connected to the connecting plate 129, and a handle is provided on the connecting plate 129.

The transmission block 131 can be moved a specified distance as needed, thereby driving the second baffle 120 to rotate a specified angle relative to the first baffle 119, so that the second through slot and the first through slot are staggered to adjust the size of the fan air inlet to cope with different usage scenarios in dusty environments and fine dust environments.

[0052] After the movable block 110 moves to the bottom of the third movable groove 114, the second fixed block 113 is inserted into the second fixed groove to fix the transmission block 131.

[0053] If it is necessary to continue moving the transmission block 131 to increase the gear, the push plate 122 is pushed toward the top of the push rod 123. The push plate 122 drives the movable block 110 to rise. After the second fixed groove is disengaged from the second fixed block 113, the movable block 110 is pressed against the bottom of the stop block 116 to push the stop block 116 to move. The stop block 116 drives the third baffle 115 to move so that the third baffle 115 moves to a position above the second groove 127. At this time, the third baffle 115 is staggered with the movable rod 124 at this location, and the transmission block 131 can be pushed forward to make the second baffle 120 continue to rotate.
