The working principle of the floor washing machine provided by the embodiment of the invention is as follows:

when the sofa bottom, the bed bottom and the like need to be cleaned, the first shell 11 is firstly rotated by 90 degrees or 270 degrees around the central axis of the first rotating block 15, and then the first connecting pipe 141 is rotated so that the moving wheel 13 on the first shell 11 can be contacted with the ground; through setting up sewage box 2 in first cavity 311, when the arbitrary angle of first casing 11 slope, sewage also can not spill over to through promoting handrail 12, can make that the round brush 32 can be better clean at the bottom of the sofa and the bed, reduce the loss of manpower, it is more laborsaving.

When the rolling brush 32 is used for cleaning the ground, firstly, clean water flows into the water storage cavity 351 through the clean water tank and flows to the filtering teeth 315 through the water outlet 352; and flows onto the drum brush 32 through the filter teeth 315, increasing the cleaning ability of the drum brush 32 to the floor. Through setting up the clear water tank in first casing 11 for the whole focus of scrubber reduces, uses more laborsavingly.

Meanwhile, the suction fan is started, so that air in the box body 22 enters the airflow channel 312 from the sewage suction port 23 and then enters the first connecting pipe 141 through the second connecting pipe 316 to be discharged, negative pressure is formed in the box body 22, dirt at the inlet 313 of the collecting channel can be adsorbed, the dirt enters the box body 22 through the outlet 314 of the collecting channel through the sewage inlet 25 to be stored, meanwhile, the water-vapor separation filter screen can enable sewage to be reserved in the box body 22, and the sewage is prevented from entering the second connecting pipe 316. By arranging the box body 22 in the first cavity 311, the distance between the sewage inlet 25 and the collecting channel inlet 313 is short, so that the residual dirt is not easy to remain, the cleaning is convenient, and the risks of pipeline blockage and odor are avoided; and because the suction route is short, only need miniwatt suction fan can satisfy the suction requirement, make the cost of scrubber is lower, and the equipment noise that produces is also lower, and the energy consumption is few, and the time of endurance is longer.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
