When the dust filter 8 needs to be removed for maintenance, pull the handle 146 to make the limit rod 142 slide inside the connecting plate 141, the clamping plate 144 disengages from the dust filter 8, the positioning hole 145 disengages from the first positioning rod 10, and the limit spring 143 is compressed. Then move the handle 146 to make the slider 13 on the front side of the connecting plate 141 slide inside the sliding frame 12. When the positioning hole 145 is aligned with the second positioning rod... When the device is horizontally aligned, release the handle 146. The limit spring 143 returns to its original position, causing the limit rod 142 to slide inside the connecting plate 141 until the positioning hole 145 is fitted onto the outside of the second positioning rod 11. At this point, the clamping plate 144 and the press switch 15 are tightly engaged, thus opening the press switch 15. The lighting lamps 16 located on the top and left and right inner walls of the casing 1 are turned on, illuminating the inside of the casing 1 for easy maintenance. Afterward, remove the dust filter 8, allowing the sealing ring 7 to disengage from the sealing groove 6 and the perforated plate 9 to disengage from the first positioning rod 10, enabling maintenance of the inside of the device. After cleaning the water tank, cleaning the dust filter 8, or replacing or repairing the water curtain 3, and completing the overhaul of the chassis 1, install the dust filter 8 on the air inlet 4, insert the sealing ring 7 into the inner side of the sealing groove 6, and fit the perforated plate 9 on the outer side of the first positioning rod 10. Next, pull the handle 146 to make the limit rod 142 slide inside the connecting plate 141, so that the positioning hole 145 disengages from the second positioning rod 11, the pressing plate 144 disengages from the press switch 15, the lighting lamp 16 goes out, the limit spring 143 is compressed, and then move the handle 146 so that the slider 13 on the front side of the connecting plate 141 is in the sliding frame 12. When the positioning hole 145 is horizontally aligned with the first positioning rod 10, the handle 146 is released, and the limit spring 143 resets, causing the limit rod 142 to slide inside the connecting plate 141 until the positioning hole 145 is fitted onto the outside of the first positioning rod 10. At this time, the pressing plate 144 is tightly fitted with the dustproof net 8, and the inner side of the sealing ring 7 is tightly fitted with the outer side of the sealing groove 6, thus completing the installation of the dustproof net 8. The setting of the sealing groove 6, the sealing ring 7 and the positioning component 14 makes the installation and disassembly of the dustproof net 8 simpler, which facilitates the maintenance of the air cooler and does not affect the sealing performance of the dustproof net 8.
