That is, when the cover plate 20 is mounted on the bottom plate 11 of the body 20, the roller brush contact portion 50 can be closely abutted to the fitting portion 40, so that the roller brush can be fixed without separately providing a roller brush locking portion, and the operation is simple.

Specifically, the roll brush cover plate 20 includes a front plate body 21 and a rear plate body 22 which are disposed in front and rear, wherein the front plate body 21 includes a plurality of front air inlets 23 on a front end surface thereof, a plurality of air inlet holes 24 penetrating the interior thereof, and a roll brush contact portion 50 facing upward, that is, at a position of the roll brush 30. And a reinforcing rib 25 is arranged between every two adjacent air inlet holes, the front air inlet 23 is communicated with the air inlet hole 24, the air inlet hole 24 is communicated with the rolling brush cavity 12, and fluid enters the air inlet hole 24 through the front air inlet 23 and then enters the rolling brush cavity.

Preferably, a plurality of protrusions 26 are further provided on the front end surface of the front plate body 21 for easy and quick installation of the cover plate 20. A fitting hole for fitting the boss 26 is provided in the inner wall surface of the roll brush chamber 12. When the brush roll cover 20 is assembled to the body 10, the protrusions 26 are placed in the assembly holes of the body 10. At least one through hole 27 is formed in the rear plate body 21, and a locking screw is provided in the through hole 27. When the rolling brush cover plate 20 is assembled to the dust removing brush body 10, it can be placed in the through-hole by the locking member and rotated to be engaged with the locking screw. The position on the bottom plate 11 close to the rear edge of the rolling brush cavity 12 is provided with a locking part, and when the rear plate body 21 of the cover plate is contacted with the bottom plate 11, the locking part is arranged in the through hole and is matched with the locking thread after rotating. The rolling brush cover plate is assembled on the bottom plate through the convex part and the locking piece. Alternatively, the through hole 27 is not provided with a screw thread, and a screw hole is provided in the body 10, and the rear plate 21 is fixed to the body 10 by a locking member.

The rolling brush contact part 50 is located at one end of the front plate body 21, and when the rolling brush cover plate 20 is fixed to the body 10, the top end of the rolling brush contact part 50 is in close contact with the fitting part 40 at one end of the rolling brush 30 to fix the rolling brush end part in the rolling brush cavity 12 and fix the position thereof.

Preferably, the rolling brush 30 further includes a rolling brush end cap 31, and the fitting portion 40 is provided on the rolling brush end cap 31. The brush roller contact portion 50 includes a first contact portion 51 and a second contact portion 52, the fitting portion 40 includes a first fitting portion 41 and a second fitting portion 42, the first contact portion 51 contacts the first fitting portion 41, and the second contact portion 52 contacts the second fitting portion 42. Preferably, the top end of the first contact portion 51 has a plane structure, the top end of the second contact portion 52 has a concave arc structure, the first mating portion 41 has a square outer wall surface, and the second mating portion 42 has a circular outer wall surface. That is, the planar structure of the first contact portion 51 is in close contact with the square outer wall surface of the roller end cover 31, and the arc-shaped structure of the second contact portion is in close contact with the circular outer wall surface of the second fitting portion 42, so as to double-fix the roller end surface. Preferably, the second fitting portion 42 is located inside the first fitting portion 41 to make the fixation more stable.

The roll brush 30 is fixed in the roll brush chamber 12 by the roll brush contact 50, and the roll brush contact 50 needs to apply a large pressure to the roll brush 30. When the rolling brush contact part 50 applies pressure to the rolling brush end part, in order to ensure the self-strength of the rolling brush contact part 50, the heights of the first contact part 51 and the second contact part 52 are not too high, so that a raised part 29 is further arranged on the cover plate 20, and the bottoms of the first contact part 51 and the second contact part 52 are both positioned on the raised part 29. The heights of the first contact portion 51 and the second contact portion 52 can be reduced by the raised portion 29.

In order to provide the roller brush contact part 50 with a certain flexibility, that is, to accommodate roller brush fixation with different machining accuracies, a gap is provided between the first contact part 51 and the second contact part 52, and therefore, in order to further increase the strength between the first contact part 51 and the second contact part 52, an intermediate part 53 connected to both the first contact part 51 and the second contact part 52 is further provided in the gap, and the bottom part of the intermediate part 53 is located on the raised part 29. Preferably, the height of the intermediate portion 53 in the vertical direction is the same as the height of the lowest point of the arc shape of the second contact portion, and since the first contact portion 51 is located outside the axial direction of the roll brush, that is, outside the lateral direction of the floor plate, the height of the first contact portion 51 in the vertical direction is greater than the second contact portion 52 and the intermediate portion 53, so that the fixation is more firm.

When the rolling brush cover plate 20 is fixed on the base plate 11, the rolling brush contact portion 50 is in close contact with the fitting portion 40 of the rolling brush 30 to hold the rolling brush against the rolling brush chamber 12.
