The existing floor washing machine is generally provided with a sewage tank, sewage and sundries collected by the floor brush module are conveyed and collected in the sewage tank for temporary storage through a pipeline under the negative pressure effect of the fan module, and after the cleaning work is finished, the sewage tank is directly poured and the internal space of the sewage tank is cleaned.

Due to the use characteristics of the floor scrubber in dry and wet scenes, the sewage tank structure of the floor scrubber needs certain waterproof sealing performance so as to prevent moisture from invading into a downstream fan module and further avoid damage of a fan motor. When the conventional cleaning machine is used, the machine body of the conventional cleaning machine is usually slightly inclined with the vertical direction, namely basically kept in an upright posture, so that the water and gas can not enter the blower along with the air flow only by arranging a certain seal at the position of the air outlet at the top of the sewage tank. However, under some special use scenes, the floor washing machine needs to be put down and dragged to clean some sanitary dead angles, for example, if the bottom of a bed or a wardrobe is cleaned, the floor washing machine needs to be put down for use, under such use scenes, the upper end and the lower end of the sewage tank in the vertical posture are basically positioned on the same horizontal plane, sewage collected in the sewage tank can continuously flow to the air outlet end of the sewage tank, the original sealing grade of the air outlet end of the sewage tank is not high enough to realize sealing under the use environments, and therefore, if the sewage tank is not improved, the risk of damage of a fan is greatly improved.

Therefore, the Chinese patent publication No. CN202122679738.3 (publication No. CN 216628453U) discloses a sewage tank, a sewage tank assembly and a cleaning device, wherein the cleaning device can intercept sewage in the tank by adding a water baffle to prevent water in the tank from flowing out of the tank through a water outlet part in the process of dumping the tank so as to increase the inclination angle of the sewage tank in the process of use, thereby increasing the downward pressure inclination angle of the cleaning device in the process of use.
