Secondly, the protective net 13 provided can protect one end of the circulation groove 4 to prevent debris in the environment from entering the interior of the vertical block 3 during air intake. When the protective net 13 needs to be disassembled and maintained, pull the pull rod 19 to allow the pull rod 19 to drive the plug block 15 to slide in the slot 14, so that the card block 17 can be separated from the card slot 18, thereby allowing one end of the plug block 15 to separate from the limit hole 16. At this time, the positioning block 12 can slide in the positioning slot 11, so that the protective net 13 can be disassembled and separated, so that the operator can perform maintenance operations on the protective net 13 without tools, which brings convenience to the maintenance work of the protective net 13.
