By setting a water inlet baffle, it is convenient to avoid the impact of a large flow on the filler layer when water is inlet, and ensure the safety and stability of the equipment. Further, a first hole is started on the water inlet baffle, and pollutants, suspended matter, colloids, etc. are washed away through the first hole, so as to extend the service life of the filler layer, reduce the backwashing pressure during the backwashing process, and reduce the risk of equipment operation.

At this time, the fixation of the first plug block 5 is released, and then the user rotates the sealing plate 4 by hand to rotate the sealing plate 4 in the first through groove 2. When the sealing plate 4 rotates to a suitable position, the sealing plate 4 will drive the first plug block 5 to move in the first slot 3 to the outside, and the inner cavity of the filter device body 1 will be completely exposed to the outside. The user can then clean one of the filter device bodies 1. After cleaning, the user manually rotates the sealing plate 4 in the opposite direction to allow the sealing plate 4 to drive the first plug block 5 to be inserted into the first slot 3. The user then releases the pull block 21 to allow one end of the two plug rods 17 to be respectively inserted into the first plug block 5 under the action of the elastic force of the two springs 18, thereby fixing the first plug block 5 in the first slot 3 and preventing it from moving.
