In the present embodiment, the cleaning assistance portion 23 is provided on the front side and the lower side of the guide slope 103.

The utility model discloses an in the embodiment of round brush cleaning module, in order to solve the problem that the sweep bar 20 hinders more, can turn over in order to realize clean auxiliary part 23 and roll over, dispose breach groove 2321 at sweep bar 20.

When the cleaning device works normally, the scraping strip 20 and the surface to be cleaned generate certain interference, but when the front side of the scraping strip 20 encounters obstacles such as a boss, sundries and the like, if the scraping strip 20 cannot cross the obstacles smoothly, the cleaning device cannot cross the obstacles.

In the present embodiment, the cleaning assistance portion 23 is an elastic member, and the cleaning assistance portion 23 can maintain interference with the floor or other floors by its own elasticity. The cutaway groove 2321 is disposed between the root portion to the free end portion of the cleaning assistance portion 23, the cleaning assistance portion 23 is relatively thin in thickness at the cutaway groove 2321 to reduce deformation resistance of the cleaning assistance portion 23 at the cutaway groove 2321, and the cleaning assistance portion 23 may be folded back at the cutaway groove 2321 to approach the support portion 22.

When the scraping strip 20 is applied to a cleaning device, the cleaning device walks forwards on a surface to be cleaned, when an obstacle in front of the scraping strip 20 blocks the forward route of the cleaning device, the cleaning auxiliary portion 23 turns over backwards and upwards under the action of the obstacle until the walking device walks forwards until the cleaning auxiliary portion 23 crosses the obstacle, and after the obstacle crossing is completed, the cleaning auxiliary portion 23 turns over forwards and downwards under the action of elasticity of the cleaning auxiliary portion to reset.

In this embodiment, the cleaning auxiliary portion 23 may be folded at the notch slot 2321 to a position substantially parallel to the surface to be cleaned, so as to provide an obstacle crossing and avoiding position.

The cutaway groove 2321 is provided at the rear side of the wiper strip 20.

When the scraping bar 20 meets an obstacle, the front side of the scraping bar 20 contacts the obstacle, the notch groove 2321 is arranged on the rear side instead of the front side, the flatness of the front side surface of the scraping bar 20 can be kept, and dust, sundries and sewage are prevented from being accumulated in the notch groove 2321 on the front side.

The shape of the notch 2321 is not limited as long as a relatively weak concave portion can be designed between the root portion and the free end portion of the cleaning assistance portion 23, and the cleaning assistance portion 23 can be conveniently turned over.

In different use scenes of the cleaning device, the roughness of the ground or other surfaces to be cleaned is different, and the included angle between the cleaning auxiliary part 23 and the supporting part 22 of the scraping strip 20 can be self-adapted according to the roughness of the surfaces to be cleaned.

In an embodiment of the cleaning module of the present invention, the material of the scraping bar 20 is a rubber wear-resistant material, that is, the scraping bar 20 is a rubber scraping bar 20. Thus, the wiper strip 20 is not easily damaged by friction, and the durability of the wiper strip 20 is improved.

In an embodiment of the present invention, the front section of the scraping bar 20 is thickened, that is, the free end of the scraping bar 20 is thickened, so as to increase the durability of the normal use of the scraping bar 20.

Referring to fig. 4 to 8, in an embodiment of the cleaning module of the present invention, in order to install the scraping bar 20 and the pressing plate 14, the housing structure is configured as follows:
