2. The floor brush module according to claim 1, characterized in that: The nozzle is a rectangular parallelepiped structure, and the length direction of the nozzle is consistent with the length direction of the roller brush.

3. The floor brush module according to claim 2, characterized in that: The cleaning box is provided with a water inlet, and the water inlet is provided with a cleaning box cover. The cleaning box injects liquid into the cleaning box through the water inlet, and the cleaning box cover is used to seal the water inlet.

4. The floor brush module according to claim 1, characterized in that: The driving member is a roller brush motor, and the floor brush module also includes: Two gears are respectively arranged on the output shaft of the roller brush motor and the roller brush, the two gears are meshed with each other, and the roller brush motor drives the roller brush to rotate through the two gears.

5. A wet and dry vacuum cleaner, characterized in that: It comprises a suction pump, a separator, an extension rod, a dust bucket assembly and a floor brush module as claimed in any one of claims 1 to 4; The first end of the extension rod is detachably arranged on the floor brush module, the second end of the extension rod is detachably connected to the input port of the dust bucket assembly, the output port of the dust bucket assembly is detachably connected to the first end of the separator, and the second end of the separator is detachably connected to the suction port of the suction pump; When the suction pump provides adsorption force to the extension rod through the separator, the floor brush module adsorbs dust and / or liquid on the floor into the extension rod, and the dust bucket assembly is used to collect dust and / or liquid in the extension rod.

6. The wet and dry vacuum cleaner according to claim 5, characterized in that: The dust bucket assembly comprises: A dust bucket filter, wherein an input port of the dust bucket filter is detachably connected to the second end of the extension rod, and an output port of the dust bucket filter is detachably connected to the first end of the separator; A dust bucket, wherein the dust bucket is sleeved on the dust bucket filter; Wherein, the dust bucket filter is used to isolate dust in the dust bucket.

7. The wet and dry vacuum cleaner according to claim 6, characterized in that: The wet and dry vacuum cleaner also includes: An exhaust filter is disposed on the exhaust port of the suction pump, and is used to filter odorous gases and / or tiny dust particles discharged by the suction pump.
