[0030] As shown in Figure 2 , Figure 3 and Figure 5 , the self-locking mechanism 25 comprises: the three pawls 19 are provided with a matching pressing ring 26, the pressing ring 26 is rotatably connected with the fixed sleeve 8, and the top of the pressing ring 26 is fixedly connected with a worm wheel 27; the inside of the protection box 7 is provided with a second rotating shaft 28, one end of the second rotating shaft 28 is rotatably connected with the protection box 7, the other end of the second rotating shaft 28 extends to a knob 29 through the protection box 7, the knob 29 is fixedly connected with the second rotating shaft 28, the outer surface of the second rotating shaft 28 in the protection box 7 is fixedly connected with two worm gears 30, the worm wheel 27 is meshed with the worm gear 30, the user can rotate the knob 29, the knob 29 drives the second rotating shaft 28 to rotate, the second rotating shaft 28 rotates at the same time and drives the worm gear 30, the worm gear 30 rotates at the same time and drives the worm wheel 27 to rotate respectively, the worm wheel 27 rotates at the same time and drives the pressing ring 26, the user can control the forward and reverse rotation of the pressing ring 26 by controlling the forward and reverse rotation of the knob 29.

[0034] Working principle: When the fan 5 is started, it draws dust through the pipe and then transports the dust into the connecting box 6. The air pressure inside the connecting box 6 increases, causing air and dust to enter the first filter cartridge 13 through the fixed sleeve 8. Due to the increased air pressure inside the first filter cartridge 13, the air is compressed and forced to pass through the first filter cartridge 13, meltblown cloth 14, filter cotton layer 15, and second filter cartridge 16 into the dust collection box 2. As the air passes through the first filter cartridge 13, meltblown cloth 14, filter cotton layer 15, and second filter cartridge 16, it can remove dust from the air. By employing both blocking and adsorption, four sets of filtration mechanisms 9 simultaneously filter dust inside electrical automation equipment. This not only filters larger dust particles but also adsorbs finer dust, improving the dust removal efficiency of the device. This solves the problem that existing dust removal devices for electrical automation equipment use dust collector bags to remove dust inside the equipment, but because the pore size of the filter bags cannot be changed, they can only filter dust larger than the pore size, resulting in a limited filtration effect and poor dust removal performance.
