Pull the top cover 3 away from the housing 1, the first connecting block 702 is separated from the connecting rod 703, rotate the top connecting rod 703, the top connecting rod 703 is separated from the remaining connecting rods 703. After the top connecting rod 703 is separated, the upper filter screen 9 can be removed. Then, the middle connecting rod 703 can be removed, and the bottom filter screen 9 can be removed. Since the receiving block 8 is fixedly connected to the front, rear, left and right sides inside the housing 1, the bottom filter screen 9 can be taken out from inside the housing 1 vertically between the receiving blocks 8. After the bottom filter screen 9 is removed, the bottom connecting rod 703 can be pulled out from the second connecting block 705. After the parts inside the housing 1 are removed, the parts and the inside of the housing 1 can be cleaned and maintained respectively.
