Description

Technical Field

[0001] The utility model specifically relates to a full-automatic floor cleaning machine. Background Art

[0002] As people's living standards continue to improve and society continues to progress, the area of ​​places that need to be cleaned is getting larger and larger. Manual cleaning is not only slow but also ineffective. At present, people are increasingly using fully automatic floor scrubbers to clean large areas of the floor. The existing fully automatic floor scrubbers include a floor scrubbing system, a sewage recovery system, and an electrical control system. The cleaning brush disc of the floor scrubbing system is installed at the bottom of the floor scrubber.

[0003] However, when the floor scrubber is moving, especially on a bumpy road, the brush plate at the bottom is easily damaged by impact. When encountering stairs, the floor scrubber needs to be lifted to cross the stairs, which makes it more difficult for operators with less strength to operate the machine.

[0004] Moreover, the existing floor scrubber cleaning brush disc does not have the function of lifting. When cleaning the floor, the roller and the bottom of the cleaning brush disc cannot be on the same plane and in close contact with the floor. Only the cleaning brush disc is in contact with the floor, and the roller is not in contact with the floor. The floor scrubber will swing left and right with the operator's feet as the center of the circle, which will generate a large noise due to vibration and shorten the service life of the floor scrubber.

[0005] The existing cleaning brush disc is integrated with the floor scrubber. When a fault occurs, it is not easy to disassemble the cleaning brush disc, which increases the maintenance cost of the cleaning brush disc. Utility Model Content
