[0002] Submersible fans are designed specifically for underwater environments. They can be installed directly in water bodies and used for various water treatment and oxygenation applications. They primarily draw in air, compress it, and deliver it underwater. This process typically involves the rotation of an impeller, driven by a motor at high speed, generating centrifugal force that compresses the air and delivers it to a submersible aerator. Underwater, the compressed air is released through the aerator, forming tiny bubbles that increase the dissolved oxygen content in the water and improve water quality.
[0003] However, although traditional submersible fans can meet the use requirements in specific environments to a certain extent, they have some shortcomings in terms of protection performance. For example, the design of traditional submersible fans often ignores the protection of the air inlet duct, causing dust and other suspended particles to enter the fan, causing rapid wear and corrosion of the internal parts of the fan, and even leading to fan failure, affecting the service life of the fan.

[0026] Working principle: When the submerged fan body 1 is working, it inhales the outside air through the air inlet 5 on the processing box 3, and then filters out the dust and other suspended particles in the air under the action of the dust filter frame 7, thereby reducing the possibility of external dust entering the interior of the submerged fan body 1 and causing damage to the submerged fan body 1, thereby prolonging the service life of the submerged fan. When it is necessary to clean and replace the dust filter frame 7, just pull the T-shaped block 12 to drive the movable frame 11 to slide to the right along the guide rod 9 and compress the first spring 10 to release the restrictive effect of the movable frame 11 on the dust filter frame 7, and then Under the restoring force of the second spring 16 in the stretched state, the dust filter frame 7 will be pushed upward through the slide rod 14, and then the handle 17 can be pulled out to quickly pull out the dust filter frame 7 to complete the disassembly.
