The filter plate 7 is provided with a limiting groove 71 at a position corresponding to the locking tongue 611. The locking tongue 611 passes through the latch hole 612 on the air filter cover 6 and is inserted into the limiting groove 71 to lock the filter plate 7.

[0021] The push rod 62 is arranged in front of the locking tongue 611. Pressing the push rod 62 causes the push block 621 on the push rod 62 to press down along the locking tongue 611, pushing the locking tongue 611 to the retracted position to unlock the filter plate 7.

[0022] The push rods 62 are connected by a sleeve rod 63, and the sleeve rod 63 is slidably sleeved on the push rod outer 62 and abuts against the push block 621. A main push rod 631 is fixedly connected in the middle of the sleeve rod 63. Pressing the main push rod 631 causes the sleeve rod 63 to push the push block 621, so that the filter plates 7 are unlocked at the same time, so that multiple filter plates 7 can be unlocked synchronously, so that multiple filter plates 7 can be taken out at the same time.

[0023] See also Figure 3 The latch 61 includes a first latch 613 and a second latch 614, and the push rod 62 includes a first push rod 623 and a second push rod 624. The latch 61 is sleeved with a first spring 66, and the first spring 66 can pop the latch 61 out to lock the filter plate 7.

[0024] By setting up a detachable multi-stage filter, the problem of accumulation during the filtration process can be reduced, and the filter can be easily disassembled, replaced and cleaned, effectively improving the filter disassembly efficiency and maintenance efficiency.

[0025] See also Figure 3 The side wall of the air filter cover 6 is provided with a slide groove 64, and the filter plate 7 is slidably connected to the air filter cover 6 through the slide groove 64. The inner wall of the air filter cover 6 is provided with a protrusion 65, and the protrusion 65 is sleeved with a second spring 67. The filter plate 7 is provided with a groove 72 corresponding to the position of the protrusion 65, and the second spring 67 abuts against the groove 72. There are multiple filter plates 7, and dust-proof filters or moisture-proof filters can be installed on the filter plates as needed. A coarse filter 68 is installed at the top of the air filter cover 6 to perform coarse filtering on the air.

[0026] See also Figure 1 A sealing strip is installed at the connection between the filter plate 7 and the air filter cover 6.
