AI Technical Summary

⚠Technical Problem

Existing floor scrubbers have complex water tank structures and small volumes, and the wastewater pipes take up space, resulting in a non-compact design.

⚗Method used

A water tank for a surface cleaning device is designed, comprising a first chamber and a second chamber, with a wastewater pipe extending from the outside of the second chamber to the outside of the first chamber. The first chamber is used to contain dirt, and the second chamber is used to contain cleaning liquid. The wastewater pipe is located on the outside of the tank, simplifying the structure.

🎯Benefits of technology

It enables the simultaneous containment of cleaning liquid and waste in a single tank, with the wastewater pipe located on the outside of the tank, resulting in a simpler structure, a larger first chamber volume, and a design that meets the requirements for comfortable human-machine operation.
