[0101] In this embodiment, the rotation mechanism includes:

[0102] The motor 61 is vertically arranged on the box body;

[0114] In order to clean the dust on the handlebar of the beach buggy as much as possible, an electrostatic repulsion method is set to ensure that the dust on the surface of the handlebar of the beach buggy is blown off as much as possible, and then the static electricity is eliminated by the cyclone dust collector 31 and finally collected by the dust bag 32.

[0115] The dust removal device for the surface of the handlebar of the beach buggy in this embodiment is used as follows. Install the air intake filtering mechanism, open the door panel on the door opening 113, control the two horizontal cylinders 52 to shorten, insert one end of the handlebar of the beach buggy into the jack 511, and then control the two horizontal cylinders 52 to extend, so that the two clamping plates 521 clamp and fix the handlebar of the beach buggy.

[0116] Finally, close the door panel of the door opening 113, start the motor 61, the cyclone dust collector 31, the negative pressure generator 4 and the positive pressure gas generator. The blowing pipe 72 rotates around the handlebar of the beach buggy, and the air outlet nozzle 73 blows air against the handlebar of the beach buggy to blow off the dust on its surface. The dust is charged statically and moves towards the cyclone dust collector 31. When it contacts the cyclone dust collector 31, the charge is transferred and it becomes uncharged, and finally enters the dust bag 32.

[0117] After the cleaning is completed, turn off the motor 61, the cyclone dust collector 31, the negative pressure generator 4 and the positive pressure gas generator, and take out the cleaned handlebar of the beach buggy in the reverse order of the above steps.
