[0001] This utility model relates to the field of sweeping machine technology, specifically to a mop roller structure and an integrated sweeping and mopping sweeping machine. Background Technology

[0002] With the development of technology, more and more smart home appliances are entering our lives. Among them, intelligent robotic vacuum cleaners are one of the most common smart home appliances in modern households. Using machine intelligence to replace manual cleaning and automatically clean the floors of a room is called an intelligent robotic vacuum cleaner. Intelligent robotic vacuum cleaners have evolved from random cleaning and planned cleaning to navigation-based mapping cleaning, and now to the three-in-one function of vacuuming, sweeping, and mopping. Their functions include sweeping, vacuuming, and mopping, making them an essential floor cleaning tool for modern homes, offices, and other spaces.

[0003] Some existing robotic vacuum cleaners, including the main body and the mop roller located at the bottom of the main body, require connecting structures at both ends of the mop roller to rotate and connect with the main body. When cleaning corners, the above-mentioned connecting structures result in a large gap between the end of the mop roller and the wall surface, making it difficult for the mop roller to clean the corners (i.e., the floor near the wall). This leads to poor cleaning effect and low cleaning efficiency in corners. Utility Model Content

The machine body is equipped with a drive unit for driving the mop roller structure to rotate circumferentially. The mop roller structure includes a main roller and an auxiliary roller connected to one end of the main roller. The end of the main roller away from the auxiliary roller is connected to the rotation output end of the drive unit. When the drive unit operates, it drives the main roller to rotate, and the main roller drives the auxiliary roller to rotate synchronously. A fixing member is provided between the main roller and the auxiliary roller for connection to the machine body, and the main roller can rotate relative to the fixing member. During cleaning, the side of the machine body closest to the wall is the wall-facing end face, and the end of the auxiliary roller away from the main roller is flush with or close to the wall-facing end face.
