As shown in fig. 1 to 3, a multifunctional sander comprises a machine body 1 and a sanding head 2, wherein the sanding head 2 is connected with the machine body 1 through a rotating shaft 3, and the multifunctional sander further comprises:

the dust cover 4 is arranged on the outer side of the rotating shaft 3, and a first electromagnet 41 is arranged on the dust cover 4;

the dust collecting box 5 is arranged on the outer side of the dust cover 4 and communicated with the inner side of the dust cover 4, and the dust collecting box 5 is provided with a second electromagnet;

the delay switch 6 is used for controlling the second electromagnet to be later than the first electromagnet 41 to be powered off;

and the dust collector 7 is connected with the dust cover 4.

The machine body 1 is internally provided with a motor and a power supply, the polishing head 2 is driven to rotate, the delay switch 6 is a delay off-time relay, Tai Li QF _ RD21 is adopted, when the machine is closed, a user presses the switch, the motor for driving the polishing head and the first electromagnet 41 are powered off, and then after the set time length is waited, the second electromagnet is powered off. The dust collector 7 adopts a miniature dust collector, and is convenient to use. The dust collector 7 is controlled by the time delay switch 6 and is electrified and deenergized with the first electromagnet 41 at the same time. The above is the prior art, and the principle and structure thereof are not described herein again.

When the dust collector is used, the time delay switch 6 is turned on, the polishing head 2, the first electromagnet 41 and the second electromagnet are simultaneously electrified, meanwhile, the dust collector 7 starts to work, the polishing head polishes the surface of equipment, fine scraps polished on the surface of the equipment enter the dust cover 4 under the action of gravity and the suction force of the dust collector and are adsorbed on the dust cover 4 under the action of the first electromagnet 41, meanwhile, a part of fine scraps are directly adsorbed into the dust collection box 5, and a part of fine scraps, dust, impurities and the like which cannot be adsorbed by the magnets are adsorbed by the dust collector; after the polishing is finished, the delay switch 6 is closed, the polishing head 2 stops polishing, the first electromagnet 41 and the dust collector 7 are powered off, the second electromagnet is still powered on, the fine scraps fall down in the dust cover 4 and are absorbed into the dust collection box 5 under the action of the second electromagnet, after the dust collection box 5 waits for a period of time, the second electromagnet is powered off, the ground fine scraps are collected in the dust collection box 5, and the dust collection box can be cleaned in a centralized mode. In the embodiment, the second electromagnet is powered off after the first electromagnet is powered off for 3 seconds, and sufficient time is provided for adsorbing the fine dust into the dust collection box.

The dust cover 4 comprises a conical cover 42, one end of the conical cover 42 is opened and fixed on the machine body 1, the other end is opened, and a collecting port 421 is arranged on the conical cover 42. In this embodiment, the collecting opening 421 is annularly arranged on the conical cover 42, the annular cover 43 is arranged outside the collecting opening 421, the dust collecting box 5 is arranged outside the annular cover 43, and both the dust collecting box 5 and the dust collector 7 are connected with the annular cover 43. All be equipped with first electro-magnet outside annular cover and the conical cover, the fines gets into annular cover from the conical cover, is tentatively collected by the annular cover, collects the dust collection box from the annular cover again, more is favorable to collecting. In addition, the dust collector 7 is connected with the annular cover, negative pressure is formed in the annular cover, and fine dust and dust flying in the annular cover are sucked away more uniformly through the collecting port 421 annularly arranged on the conical cover 42.
