Description

TECHNICAL FIELD

[0001] The utility model relates to a floor washing machine head rotation structure. BACKGROUND

[0002] Most of the floor washing machine heads on the market currently adopt fixed design, that is, the head part cannot be rotated and adjusted according to actual needs. Although this design ensures the stability of the machine and the simplicity of operation to a certain extent, it is not satisfactory when facing scenes that need multi-angle cleaning. For example, when cleaning corners, edge zones or needing to work around obstacles, the traditional floor washing machine often cannot achieve the ideal cleaning effect, and the operator needs to frequently move the machine or use other auxiliary tools, which not only reduces the cleaning efficiency but also increases the labor intensity of the operator.

[0003] In addition, the fixed head design also limits the flexibility of the floor washing machine in narrow spaces. In some narrow areas, such as corridors, elevator rooms or stair corners, the traditional floor washing machine may not be able to effectively cover all the ground that needs to be cleaned due to the inability of the head to rotate, resulting in incomplete cleaning or the need for manual secondary processing, which undoubtedly reduces the overall practicality of the floor washing machine.

The number of convex blocks 21 is equal to the number of slopes 61.
