Mop unit lifting device and cleaning machine

Abstract

The invention discloses a mop unit lifting device which comprises a mop unit and further comprises a lifting mechanism used for lifting the mop unit; a driving mechanism which is used for driving the mop unit to rotate; the driving mechanism adopts a first driving mechanism which does not ascend and descend together with the mop unit, the lifting mechanism and the mop unit are arranged integrally or separately, or the driving mechanism adopts a second driving mechanism which ascends and descends together with the mop unit, but the lifting mechanism and the mop unit are arranged separately. The mop has the advantages that the mop unit is directly lifted, the problem that the lifting part is heavy is solved; the invention further provides a cleaning machine which adopts the mop unit lifting device.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a lifting device for a mop unit and a cleaning machine. Background technique [0002] There is a cleaning machine that has important market value because it can automatically rotate and mop the floor. However, each rotating mop unit in the current cleaning machine is usually lifted as a whole, that is, it drives the frame on which each mop unit is installed. Or the overall lifting of the housing, each drive mechanism needs to be installed on the frame or the housing, and the driving mechanism is used to drive the mop unit to rotate and clean, that is to say, the mop unit is indirectly lifted and lowered, which leads to a heavier overall weight. The applicant found that the overall lift The technical route makes the center of gravity easy to change, which has a negative impact on the stable operation of the cleaning machine. Therefore, in the process of design, producti...

[0002] There is a cleaning machine that has important market value because it can automatically rotate and mop the floor. However, each rotating mop unit in the current cleaning machine is usually lifted as a whole, that is, it drives the frame on which each mop unit is installed. Or the overall lifting of the housing, each drive mechanism needs to be installed on the frame or the housing, and the driving mechanism is used to drive the mop unit to rotate and clean, that is to say, the mop unit is indirectly lifted and lowered, which leads to a heavier overall weight. The applicant found that the overall lift The technical route makes the center of gravity easy to change, which has a negative impact on the stable operation of the cleaning machine. Therefore, in the process of design, production, and manufacturing, special attention must be paid to the matching of the center of gravity under different circumstances of lifting. Not only the structure is complicated, but also the design, production , manufacturing are more cumbersome, the cost is relatively high
