Of course, the cam 1 may be configured as a wheel having another shape such as an oval shape, and is not limited thereto. Thus, the cam 1 is constructed in a polygonal structure to reduce the jitter due to eccentricity and to increase the reciprocating frequency by increasing the length of the diameter.

In some embodiments, the cross-sectional profile of the cam 1 perpendicular to the rotation axis is a smooth curve, and the smooth curve comprises a plurality of curve units with continuously-changed derivatives and connected end to end; the distances between two continuous points on the curve unit and the connecting line of the rotation center are unequal, at least one long diameter and at least one short diameter exist between the curve unit and the rotation center, and the number of the long diameters is equal to that of the short diameters.

The cam 1 is thus designed as an eccentric cam 1, and the radial outer circumference of the cam 1 can be designed as a smooth curve, so that the outer circumferential wall of the cam 1 in the circumferential direction is continuously variable in places, i.e. the derivative function is continuous. Of course, the radial outer peripheral surface of the cam 1 may be configured as a non-smooth curved surface, and the curve may be continuously derived everywhere, i.e., a non-smooth curve, which is not limited herein.

Further, the long diameters of two adjacent curve units are symmetrically arranged and/or the short diameters of two adjacent curve units are symmetrically arranged, so that the motion of the cam 1 in rotation around the rotation axis is smoother.

Specifically, the included angle between each long diameter and two circumferentially adjacent long diameters is the same, the included angle between each short diameter and two circumferentially adjacent short diameters is the same, the lengths of any two long diameters are equal and the lengths of any two short diameters are equal, so that the value of the decrease in the radial length of the curve element from the long diameter to the short diameter direction is equal to the value of the increase in the radial length of the adjacent curve element from the short diameter to the long diameter direction in the same unit time. Therefore, the connecting line between any two points in the circumferential direction of the cam 1 and the length of the line segment passing through the rotating axis are the same, so that the movement of the cam 1 is ensured to be smoother when rotating around the rotating axis.

In some embodiments, the side of the carriage 3 facing away from the complete machine 5 has a cleaning portion for contacting the floor.

Preferably, the cleaning part can be a mop, a brush, etc., and of course, the cleaning part can be constructed in other structures, which are not limited herein. Therefore, after the mopping plate 3 is arranged on the whole machine 5, the cleaning part is directly contacted with the ground, so that the mopping machine 100 can automatically clean the ground through the cleaning part, and the automation degree of the mopping machine 100 is enhanced.
