The liquid storage barrel 20 serves as a cleaning liquid barrel and a recycling barrel for containing sewage, the cleaning liquid can be discharged from an outlet 22 of the liquid storage barrel 20, and the sewage can enter the liquid storage barrel 20 from an inlet 21 of the liquid storage barrel 20.

One end of the sewage channel 30 is communicated with the inlet 21, and the other end of the sewage channel 30 is communicated to the ground brush 10. One end of the cleaning liquid channel 40 is communicated with the outlet 22, and the other end of the cleaning liquid channel 40 is communicated to the ground brush 10. The waste water passage 30 and the cleaning liquid passage 40 may be formed of pipes or passages defined by internal structures in the body of the washing machine as long as predetermined flow paths for the cleaning liquid or waste water are defined.

The atomization device 50 is disposed in the liquid storage barrel 20 and is used for atomizing the liquid in the liquid storage barrel 20 into water vapor. The atomization device 50 in this embodiment is preferably an ultrasonic atomization sheet, and the atomization principle of the ultrasonic atomization sheet is to break up molecular bonds between liquid water molecules by high-frequency oscillation of electrons and high-frequency resonance of a ceramic atomization sheet to generate naturally elegant water mist, so that heating or addition of any chemical reagent is not required, and the atomization device is economical and environment-friendly. Of course, other atomization methods can be adopted, for example, a heating device is arranged in the liquid storage barrel 20 to heat the liquid in the liquid storage barrel 20, vapor is generated in the heating process, and the vapor is rapidly atomized into vapor when meeting cold air. Those skilled in the art can design other atomization manners according to actual requirements, and the embodiment is not particularly limited.
