When the infrared distance measuring sensor 4 detects that someone is close to the equipment and the distance is lower than a set value, the infrared distance measuring sensor can send a signal to the PLC, the PLC controls the driving assembly to work to drive the screw rod 7 to rotate, so that the screw rod 7 and the sleeve 9 can move relatively, the sleeve 9 is fixed on the base 1, so that the main body 2 can be jacked up, the main body 2 can move upwards, the function of lifting the main body 2 is realized, the probability that fingers of children stretch into the protective net 3 is reduced, the fingers of the children are prevented from being damaged, the safety of the equipment is improved, when the main body 2 moves upwards, the telescopic pipe 10 can be stretched, so that the fixing assembly can work, the base 1 can be adsorbed on the ground, the function of fixing the position of the base 1 is realized, the equipment is prevented from falling due to mistaken collision, the probability of equipment damage can be reduced, and the stability of the equipment when the equipment is placed on the ground is improved, the reliability of the device is improved. Because sleeve pipe 9's rigidity, thereby can restrict the position of dust removal pole 18 through the work of removal subassembly, when main part 2 takes place to remove, main part 2 takes place relative movement with sleeve pipe 9, thereby make main part 2 can take place relative removal with dust removal pole 18, make the brush scrape the dust of adhesion on with filter screen 15, the function of clearing up filter screen 15 has been realized, the practicality of equipment has been improved, through the collection subassembly that sets up, make dust removal pole 18 can fall on baffle 16 with the dust that scrapes on filter screen 15, the function of collecting the dust has been realized, the dust falls subaerial when avoiding removing dust, thereby prevent to cause the pollution to ground, avoid influencing the clean and tidy on ground, need not artificial clearance ground, thereby prevent to increase user's work burden, the convenience of equipment has been improved.

Compared with the prior art, the air conditioner fan with high safety can raise the main body 2 through the safety mechanism when a child approaches the equipment, reduces the probability that the child stretches fingers into the protective net 3, avoids the fingers of the child from being damaged, thereby improving the safety of the equipment, compared with the prior safety mechanism, the safety mechanism can also ensure that the base 1 can be adsorbed on the ground when the main body 2 moves upwards, realizes the function of fixing the position of the base 1, prevents the equipment from toppling over due to the accidental touch of the child, thereby reducing the probability of equipment damage, also improves the stability of the equipment when the equipment is placed on the ground, prevents the phenomenon of inclined shaking caused by the improvement of gravity when the main body 2 moves upwards, improves the reliability of the equipment, realizes the function of cleaning the filter screen 15 through the dust removal mechanism, prevents the filter screen 15 from being blocked to influence the circulation of air, and avoids the influence on the refrigeration work, thereby the practicality of equipment has been improved, compares with current dust removal mechanism, and this dust removal mechanism can also realize the function of collecting the dust, and the dust falls subaerial when avoiding removing dust to prevent to cause the pollution to ground, avoid influencing the clean and tidy on ground, need not artificial clearance ground, thereby prevent to increase user's work burden, improved the convenience of equipment.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
