At this time, the slider 10 will The sliding block 10 blocks the card slot 81 by the elastic force of the spring, and prevents the filter frame 9 from falling off the circular through slot. The fan blade 6 and the magnetic block 16 are attracted to each other by magnetic force. When the fan blade 6 rotates, the fan blade 6 passes through the side wall of the arc block 14. At this time, the fan blade 6 is attracted to the magnetic block 16 in the arc block 14, so that the magnetic block 16 slides in the arc cavity 15. When the magnetic block 16 contacts the cavity wall of the arc cavity 15, it will vibrate, and the vibration force will be transmitted to the filter screen 7, preventing the impurities on the filter screen 7 from clogging the mesh.
