[0040] Embodiment 2:

[0041] refer to Figure 5-Figure 9 , based on the above-mentioned embodiment 1, a filter mechanism is installed at the other end of the fixed shell 1, and the filter mechanism is located on the inner side of the air-permeable groove at the other end of the fixed shell 1, and the filter mechanism includes a first fixed plate 17, a second fixed plate 18, a second filter plate 19, a sliding plate 20, a first arc-shaped stopper 21 and a second arc-shaped stopper 22. The second fixed plate 18 is slidably connected to one side of the first fixed plate 17, and the second filter plate 19 is slidably connected between the first fixed plate 17 and the second fixed plate 18. When the first fixed plate 17 and the second fixed plate 18 are detached, the second filter plate 19 can be detached. The first fixed plate 17 or the second fixed plate 18 is slidably connected, and a sliding plate 20 is fixed to the top and bottom of the first fixed plate 17 near one end of the second fixed plate 18. The sliding plate 20 is slidably connected to the second fixed plate 18. First arc-shaped limit blocks 21 are evenly fixed on both sides of the sliding plate 20. Second arc-shaped limit blocks 22 are evenly fixed inside the second fixed plate 18 and at positions corresponding to the sliding plate 20, so that when the sliding plate 20 enters the inner side of the second fixed plate 18, the sliding plate 20 is positioned by the staggered first arc-shaped limit blocks 21 and the second arc-shaped limit blocks 22;

[0042] The first fixing plate 17 and the second fixing plate 18 are both slidably connected to the inner side of the ends away from each other with a sliding shell 23, and the sliding shell 23 is fixed to the fixed shell 1, so that the first fixing plate 17 or the second fixing plate 18 can be detached from the sliding shell 23 through the sliding connection, and a limiting mechanism is installed on the sliding shell 23, which includes a displacement limiting plate 24, an anti-rotation plate 25, a connecting column 26, a second compression spring 27, a clamping plate 28, a fixing block 29 and a positioning column 30. The inner side of the sliding shell 23 away from the fixed shell 1 is slidably connected with a connecting column 26, so that the connecting column 26 can slide when the sliding The interior of the movable housing 23 can be both rotated and slidable. A displacement limiting plate 24 is fixed to the end of the connecting column 26 away from the fixed housing 1. The connecting column 26 is driven to move by pulling the displacement limiting plate 24. Anti-rotation plates 25 are fixed to both sides of the displacement limiting plate 24 close to the end of the sliding housing 23. The anti-rotation plates 25 are slidably connected to the sliding housing 23, so that before the displacement limiting plate 24 rotates, the anti-rotation plate 25 is slidably connected to the sliding housing 23 to limit the rotation. After the displacement limiting plate 24 rotates ninety degrees, it can also be limited to rotate by the sliding connection between the anti-rotation plate 25 and the sliding housing 23.

[0043] The connecting column 26 is close to one end of the fixed shell 1 and is located inside the sliding shell 23, and a card plate 28 is fixed thereto. A second compression spring 27 is sleeved on the outer side of the connecting column 26. One end of the second compression spring 27 is fixed to the card plate 28, and the other end of the second compression spring 27 is fixed to the sliding shell 23. When the displacement limit plate 24 moves away from one end of the fixed shell 1, the displacement limit plate 24 drives the card plate 28 to move through the connecting column 26, and the card plate 28 drives the second compression spring 27 to compress. At the same time, the card plate 28 can only rotate in one direction on the inner side of the sliding shell 23, just allowing the card plate 28 to rotate ninety degrees on the inner side of the sliding shell 23. Fixed blocks 29 are fixed inside both sides of the sliding shell 23. A positioning column 30 is fixed to one end of the fixed block 29 close to the fixed shell 1, and the positioning column 30 is slidably connected to the card plate 28, so that the card plate 28 cannot rotate when it is located on the outer side of the positioning column 30.

[0044] When the cooling fan 5 rotates to dissipate heat, after the outside air is filtered through the second filter plate 19, the air is allowed to enter the interior of the fixed shell 1, driving the hot air inside the fixed shell 1 to pass through the positioning shell 2 and then be discharged, and the first filter plate 3 is used to prevent external dust from passing through the positioning shell 2 to enter the interior of the fixed shell 1. When the second filter plate 19 needs to be replaced, the displacement limit plate 24 is pulled to allow the displacement limit plate 24 to drive the anti-rotation plate 25 and the connecting column 26 to slide away from the fixed shell 1. When the anti-rotation plate 25 just sees the sliding shell 23 that is detached from the sliding connection, the displacement limit plate 24 is rotated to allow the displacement limit plate 24 to drive the anti-rotation plate 25, the connecting column 26 and the card plate 28 to rotate, so that at the same time the card plate 28 has driven the connecting column 26 to rotate. The connecting column 26 is compressed, and the displacement limiting plate 24 is rotated ninety degrees to allow the displacement limiting plate 24 to be separated from the extrusion of the first fixing plate 17 or the second fixing plate 18, and then the first fixing plate 17 and the second fixing plate 18 are pulled out of the air vent at the other end of the fixed shell 1, and then the first fixing plate 17 and the second fixing plate 18 are pulled to move the first fixing plate 17 and the second fixing plate 18 in the opposite direction, and the sliding plate 20 is separated from the slidingly connected second fixing plate 18 through the misalignment of the first arc-shaped limiting block 21 and the second arc-shaped limiting block 22, and then the second filter plate 19 is removed for replacement, and then the above operation is repeated in reverse to install the new second filter plate 19 or the cleaned second filter plate 19.
