The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, a sewage collecting system of a floor mopping machine according to a preferred embodiment of the present invention includes a water pan 1, a sewage tank 2, a water return pipe 3, and a negative pressure water suction mechanism 4. The water receiving tray 1 is used for receiving sewage squeezed from the rolling brush, the sewage tank 2 is used for storing the sewage, the water return pipe 3 is used as a pipeline for the sewage to flow from the water receiving tray 1 to the sewage tank 2, and the negative pressure water absorption mechanism 4 is used for enabling the inside of the sewage tank 2 to generate negative pressure so as to achieve a water absorption function.
