[0019] In this embodiment: the purifier body 1 supports the support shell 2, the circulating airflow pipe 11 is connected to the purifier body 1 through the support shell 2 to transport air, and the support shell 2 intercepts and filters the air transported by the circulating airflow pipe 11 through the internal interception member, so that dust and other particles carried in the air can be intercepted and processed, and dust and other particulate impurities are prevented from entering the purifier body 1 and causing pollution to the internal purification elements and making it difficult to clean. The support shell 2 supports the sliding plate 3, and the sliding plate 3 is connected to the circulating airflow pipe 11 through two airflow grooves 31. The airflow groove 31 is connected to the intercepting net tube 32 by the airflow groove 31, and the inner size of the airflow groove 31 is larger than the intercepting net tube 32, so that there is a gap between the intercepting net tube 32 and the airflow groove 31.

The blocking plate 21 blocks the opening on one side of the supporting shell 2. When the blocking plate 21 is opened, the intercepting net tube 32 The net cylinder 32 can be taken out through the opening on one side of the supporting shell 2. After the intercepting net cylinder 32 is cleaned or replaced, the blocking plate 21 pushes the intercepting net cylinder 32 into the supporting shell 2 and engages with the sliding plate 3. The inner side of the blocking plate 21 is kept flush with the inner wall of the supporting shell 2, so that when the sliding plate 3 slides inside the supporting shell 2, the intercepting net cylinder 32 can slide normally, avoiding the intercepting net cylinder 32 from being disturbed and unable to slide. When the sliding plate 3 drives the intercepting net cylinder 32 to dock with the circulating airflow pipe 11, the circulating airflow pipe 11 transports air into the intercepting net cylinder 32 for interception and filtration. The sliding plate 3 drives the two intercepting net cylinders 32 to alternately intercept and filter the air transported by the circulating airflow pipe 11, so that the other intercepting net cylinder 32 in the non-working state can be cleaned and replaced, and the blocking plate 21 is opened to take out the intercepting net cylinder 32 in the corresponding position for cleaning or replacement. The intercepting net cylinder 32 can be disassembled, cleaned or replaced without stopping the operation of the purifier body 1.
