Water surface cleaning machine

Abstract

The present application provides a water surface cleaning machine, including a machine body, a drive assembly, and a roller brush assembly. The machine body includes a housing and a sealed casing that is arranged inside the housing and isolated from an outside. A first drive member is arranged inside the sealed casing, and a second drive member is arranged inside the housing and is arranged outside the sealed casing. The first drive member is magnetically connected with the second drive member. In the water surface cleaning machine provided above, two drive members are associated through magnetic driving. The first drive member is completely sealed in the sealed casing, and the second drive member rotates only under magnetic driving, which fundamentally solves the risk that a water vapor penetrates into a motor due to the failed dynamic sealing.

Dependencies are inferred from the claim text.
