[0012] 1. By setting up a filtration mechanism, the filter screen is installed between the connecting end and the connecting port, and the connection is pressed together by the rubber strips on both sides of the mounting bracket. At this time, rotating the outer adjusting rod will cause the end clamping part to move down, so that the three grooves on the inner side of the clamping part will respectively engage and limit the connection of the connecting end, the mounting bracket and the connecting port, thus ensuring the overall tight connection. The three sets of settings ensure a tight connection between the filter screen and the connecting end, improve the stability of use and ensure convenient disassembly and assembly, and facilitate the cleaning and replacement of the middle filter screen. With the end filter cover, a double filtration structure is set up to ensure that the equipment can minimize clogging during use, ensure the stability of water pumping operation and extend the service life of the equipment.

[0013] 2. By setting up the suction nozzle, and then adding suction nozzles of different specifications as needed, it can be installed by rotating the threaded section. The inner side of the threaded section has a groove that can be used to lock and install the filter cover, ensuring that the filter cover can be stably installed inside the suction nozzle. When pumping water, it filters the inside, effectively reducing the entry of large particles and sludge, ensuring normal use of the equipment, and effectively reducing the occurrence of blockages.
