A deformable sealing filter element 30 is arranged in the joint main body 10, and the sealing filter element 30 has a closed state and an open filter state; in a closed state, the sealing filter element 30 is arranged in a sealing way with the pipe wall of the joint main body 10, so that the upward flow of odor in a sewer can be prevented; in the open filter state, the sealing filter member 30 is deformed by the impact of the water flow, so that a gap is formed between the sealing filter member 30 and the pipe wall of the joint main body 10, and the water flow flows down from the gap. By arranging the sealing filter element 30, when water is drained, water flow impacts the sealing filter element 30 to deform the sealing filter element 30, a gap is formed between the sealing filter element 30 and the pipe wall of the joint main body 10, so that the water flow flows through the gap, and impurities and foreign matters in the water flow, the size of which is larger than the gap, cannot pass through the gap, so that a filtering effect is achieved; after the drainage is finished, the deformation of the sealing filter piece 30 is reset, so that the pipe wall of the joint main body 10 is arranged in a sealing way, and foreign matters in the sewer are isolated; that is, the sealing filter member 30 can perform sealing and filtering functions, which is advantageous in simplifying the structure.
