In addition, the rectangular frame unit 1 is used for providing a relatively closed housing for the suction debris sucking operation described above, and ensuring that the air flowing over the leg fitting b is as fast and as much as possible.

It should be noted that, according to the law of conservation of energy, the exhaust fan c is used for exhausting and removing impurities and pushing the annular brush unit 4, so that compared with a mode of exhausting and removing impurities alone, wind power of exhausting and removing impurities is reduced, but under the condition that the beneficial point of active brushing of the scraps is maintained, the whole scraps extraction effect and extraction rate are still greatly improved.

The rectangular frame unit 1 comprises a main frame 101, two end baffles 102 which are respectively arranged at two openings of the main frame 101 and used for increasing the wind speed on the support leg fittings b, an exhaust opening 103 which is arranged on the top plate of the main frame 101 and used for installing the round table-shaped air guide pipe unit 2, and an air blowing opening 104 which is arranged on the top plate of the main frame 101 and used for rotationally driving the annular hairbrush unit 4 in an inward blowing mode by installing the fan pipe unit 3.
