Cleaning apparatus

By introducing a second cleaning unit driven by a cantilever mechanism into the cleaning equipment, the switching between edge-fitting and non-edge-fitting states is realized, solving the problem that the side of the roller brush cannot achieve zero edge-fitting, extending the service life of the side brush, and improving the cleaning effect and user experience.

AI Technical Summary

Technical Problem

When cleaning edges, existing cleaning equipment cannot achieve zero-edge contact with the sides of the roller brush, resulting in stains remaining on the floor near walls and furniture. Furthermore, the side brushes wear out quickly, leading to a poor user experience.

Method used

A cleaning device was designed, comprising a second cleaning unit driven by a cantilever mechanism, which can switch between edge-contact and non-edge-contact states. When in edge-contact, it contacts the working surface for cleaning, and when not in edge-contact, it detaches to extend its service life. The unit is driven to rotate by the friction of the cantilever mechanism and the roller brush, thereby reducing contact with the working surface.

Benefits of technology

It achieves thorough cleaning, extends the lifespan of the side brush, reduces cleaning dead spots, and improves the user experience.

Abstract

This disclosure relates to a cleaning device, including a floor brush assembly. The floor brush assembly includes: a floor brush housing; a first cleaning unit; and a second cleaning unit. The first cleaning unit is rotatably connected to the floor brush housing along a first axis to clean a work surface. Along the first axis, the second cleaning unit is located on at least one side of the first cleaning unit. The second cleaning unit is movably connected to the floor brush housing via a cantilever mechanism. The cantilever mechanism is rotatably connected to the floor brush housing via an inclined shaft. In a projection plane on the work surface, the floor brush assembly has a central axis perpendicular to the first axis. The end of the inclined shaft closer to the work surface is defined as the first end, and the end farther from the work surface is defined as the second end. From the first end to the second end, the inclined shaft gradually tilts towards the central axis. The second cleaning unit can achieve tilting movement under the action of the cantilever mechanism, thereby avoiding continuous contact with the work surface and extending the service life of the second cleaning unit.
