Floor brush module for cleaning machine and cleaning machine

The utility model relates to a floor brush module for a cleaning machine and the cleaning machine, the floor brush module comprises a base, the front side of the base in the advancing direction of the floor brush module is also provided with an air inlet, and the base is also provided with an air outlet communicated with a downstream fan module; the wind shield can be arranged in the dust collection cavity in a front-back deflection mode, so that airflow between the air inlet and the air outlet is communicated or blocked; and the driving mechanism is in driving connection with the wind shield. When stubborn stains are cleaned, the air flow between the air inlet and the air outlet can be blocked by the air baffle, so that the suction force to water is reduced, that is, the water sprayed on the surface to be cleaned cannot be quickly sucked dry, and the cleaning effect on the stubborn stains is improved; after cleaning is completed, fluid between the air inlet and the air outlet is communicated through the air
