[0002] In the related technology, for coal mines and other mining enterprises, spray dust reduction mechanisms are often used for dust reduction treatment. Common spray dust reduction mechanisms usually include nozzles, filters, water pumps and water tanks. The water in the water tank is pumped into the nozzles through the water pumps, and then sprayed out by the nozzles. The filters filter impurities in the water in the water tank.

[0003] Although the service life of the nozzle can be extended to a certain extent, the filter will easily become clogged over time, making it difficult for high-pressure water to enter the nozzle, thereby reducing the dust reduction effect of the nozzle. Summary of the invention
