The theory of operation and the beneficial effect of this basic scheme lie in:
1. when the electric fan needs to be cleaned, the air cylinder drives the sliding plate to slide downwards, the sliding plate drives the second electrode plate to slide downwards, the first electrode plate is in contact with the second electrode plate, the low-frequency alternating-current power supply is communicated with the electromagnet, and the electromagnet is internally electrified. When the electromagnet is energized with forward current, the electromagnet repels the magnetic block, the magnetic block drives the cleaning block to move in the direction away from the rotating shaft, and when the electromagnet is energized with reverse current, the electromagnet attracts the magnetic block, and the magnetic block drives the cleaning block to move in the direction close to the rotating shaft. Namely, the cleaning block reciprocates on the fan blade to scrape off the dust on the fan blade. The cleaning block slides on the fan blades, and the fan blades are cleaned by utilizing the friction between the cleaning block and the fan blades.
2. The slide plate slides downwards, the space at the lower part of the cavity is reduced, the air pressure is increased, and the air is discharged from the air outlet one-way valve. Because the outer side end of the air outlet hole inclines upwards, air is guided by the air outlet hole and blown to the fan blade, and dust on the fan blade is blown up by matching with friction of the cleaning block and the fan blade, so that the fan blade is further cleaned.
3. When the fan blades do not need to be cleaned, the push rod slides upwards, the first electrode plate and the second electrode plate are separated, the magnetic field generated by the electromagnet disappears, the cleaning block slides and resets under the resetting action of the spring, when the magnetic block is gradually close to the rotating shaft, the magnetic block attracts an iron core of the electromagnet, drives the cleaning block to further slide towards the direction close to the rotating shaft, and stops at the end, close to the rotating shaft, of the fan blades, and the end is not moved. When the electric fan is used in daily life, the centrifugal force generated by the rotation of the fan blades cannot overcome the attraction between the magnetic block and the iron core, namely, when the electric fan is used normally, the cleaning block cannot slide randomly.
Furthermore, a push rod is eccentrically fixed at the lower end of the sliding plate, the lower end of the push rod penetrates through the lower end of the rotating shaft and extends out of the rotating shaft, a supporting rod is fixed at the lower end of the rotating shaft, a push block is connected to the supporting rod in a sliding manner, and the push block is fixed with the lower end of the push rod; the lower end of the supporting rod is fixed with a piece of blocking cloth which is circular, a plurality of supporting rods are uniformly distributed on the blocking cloth along the radial direction, the supporting rods comprise a first supporting rod and a second supporting rod which are hinged together, the joint of the first supporting rod and the second supporting rod is hinged with a connecting rod, and one end, away from the supporting rod, of the connecting rod is hinged to the pushing block.

Dust that the dust and the gas that the cleaning block was scraped blow up all can drop to keeping off on the cloth and be collected, avoid the dust to drop from the eminence, fly upward everywhere. Meanwhile, the surface of the umbrella-shaped blocking cloth is inclined, dust falling onto the blocking cloth can slide to the center of the blocking part and slide upwards on the sliding plate, and then the blocking cloth is driven to be folded, so that the dust cannot fall off from the blocking cloth and fly upwards.
Furthermore, the lower end of the supporting rod penetrates through the blocking cloth and is detachably connected with the collecting barrel, and the blocking cloth is provided with a plurality of dust outlet holes communicated with the collecting barrel.
Has the advantages that: the dust that drops to on the fender cloth slides along the surface of fender cloth, when sliding to the dust outlet hole department, drops to the collecting vessel in through the dust outlet hole. The collecting vessel and the supporting rod can be detachably connected, and the collecting vessel can be conveniently taken down for cleaning.
Furthermore, a chute for the cleaning block to slide is arranged on the fan blade, and the distance from one end of the chute far away from the rotating shaft to the free end of the fan blade is 2-4 cm.
Has the advantages that: the cleaning block is limited by the sliding groove, so that the cleaning block is prevented from sliding off the fan blade in the sliding process.
Further, the cleaning block includes clean piece and lower clean piece on the joint together, goes up clean piece and is located the flabellum upside, and clean piece is located the flabellum downside down.
Has the advantages that: the cleaning block can be conveniently detached from the fan blade for cleaning, and the upper cleaning block and the lower cleaning block can be cleaned respectively. Compare clean piece integrated into one piece, inconvenient when needing to wash the hole.
