Garbage bin and water surface cleaning robot

Abstract

Disclosed are a garbage bin and a water surface cleaning robot. The garbage bin includes a frame body having a fluid inlet, where the frame body is provided with a leakage prevention baffle, and the leakage prevention baffle arranged adjacent to the inlet is movably connected to the frame body; the leakage prevention baffle closes at least a portion of the area of the inlet when the leakage prevention baffle is in a predetermined position; on the contrary, the leakage prevention baffle opens the inlet. When the water surface cleaning robot needs to take a step back or to stop working and floats on the water surface, the leakage prevention baffle in a predetermined position can close at least part of the area of the inlet, so as to avoid the garbage in the garbage bin from leaking out from the inlet, so as to ensure the cleaning effect.
