When the electric fan stops using, the flabellum stall, and the slider slides by the reset action of first elastic component and resets, and first magnetic path resets along with the slider, and second magnetic path is kept away from to first magnetic path, and the second magnetic path drives the cleaning block and slides by the action of second elastic component and resets. Friction is generated between the cleaning block and the connecting strip, and dust falling on the connecting strip is scraped off. Meanwhile, one end of the first connecting rod slides along with the cleaning block, the other end of the first connecting rod drives the second connecting rod to deflect and reset, and the blocking cloth is spread to block the fan frame. When the electric fan is not used, the blocking cloth blocks the fan frame to prevent dust from falling on the connecting strip, and further prevent the dust falling on the connecting strip from flying with the flowing of wind when the electric fan is used again.
3. Cleaning block, first connecting rod and second connecting rod are constituteed and are used cleaning block as the slider, use the second connecting rod as articulate slider-crank mechanism, because the sliding center of cleaning block and the rotation center of second connecting rod are on same straight line, lead to cleaning block to lock at the connecting strip after straightening for avoiding first connecting rod and second connecting rod, can't slide, it is greater than the length of connecting strip to set up the length sum of first connecting rod and second connecting rod in this device, when cleaning block and ring frame paste mutually, first connecting rod, second connecting rod and connecting strip end to end form obtuse triangle, can not lock.
Furthermore, a lug is fixed at one end of the support rod, which is far away from the disc.
