Through the arrangement of the honeycomb layer 101 and the activated carbon layer 102, the device can further improve the effect of filtering air purification. A dustproof fence 4 is arranged at intervals on one side of the limiting protrusion 5 in the extension part. Through the arrangement of the dustproof fence 4, the device can discharge some dust or rainwater before the air passes through the filter core layer 1, further improving the air purification effect of the device. A push head 8 whose position is adapted to the installation frame 2 is slidably installed in the inner cavity 301, and a contact elbow 801 adapted to the connecting rod 7 is arranged on the side of the push head 8 close to the connecting rod 7.

[0027] The specific working principle of this utility model:

[0028] When the device is used, it is installed at the air inlet of the locomotive through the installation panel 3, and cooperates with the air outlet of the air duct in the cab to complete the air purification work; when the filter element layer 1 needs to be replaced, the operator presses the pressing head 6, and the pressing head 6 sinks into the inner cavity 301 and pushes the connecting rod 7 to start rotating around the rotating shaft 302, thereby pushing the movable rod 9 to move to one side. In this process, the rotation of the connecting rod 7 will push the pushing head 8 to one side of the installation frame 2, pushing the installation frame 2 to start to disengage, and at the same time, the movable rod 9 moves to the accommodating groove 901 and aligns with the movable groove 303. The movable ball 10 in the movable groove 303 is affected by the movement and squeezing of the installation frame 2, and will disengage from the locking groove 201 from the movable groove. The filter element 1 is moved from the movable groove 303 to the accommodating groove 901, and the installation frame 2 is completely out of the locking state. After the installation frame 2 is taken out, the old filter element layer 1 is removed from the side of the limiting protrusion 5 and a new filter element layer 1 is inserted; the installation frame 2 is restored, and during the process of reinstalling the installation frame 2, until its bottom contacts the push head 8, and the push head 8 is continuously squeezed to push the connecting rod 7 to rotate in the opposite direction, and the pressing head 6 is pushed out. At the same time, the connecting rod 7 will pull the movable rod 9 to move to the other side, and the accommodating groove 901 will squeeze out the movable ball 10. After the installation frame 2 is installed in place, the locking groove 201 will be aligned with the movable groove 303 again, and the movable ball 10 will enter the locking groove 201 to lock the installation frame 2, completing the whole process of replacing the filter element layer 1. During the above-mentioned whole process, the utility model cooperates with the structures such as the installation frame 2, the pressing head 6, the connecting rod 7, the movable rod 9, and the movable ball 10, so that the device can be locked and fixed after the installation frame 2 is directly inserted, and the installation frame 2 can be directly removed after pressing the pressing head 6. In this way, the installation frame 2 can be conveniently assembled and disassembled, and the filter element layer 1 can be quickly replaced, thereby improving the replacement efficiency of the filter element layer 1 of the device.
