Abstract
A lifting structure of a cleaning device, the lifting structure including a housing, a first bushing arranged to be rotatable in the housing, a second bushing that moves vertically and is rotatable with respect to the first bushing, and a middle bushing that is connected between the first bushing and the second bushing and moves vertically and is rotatable with respect to the first bushing and the second bushing.
Claims15
A cleaning device comprising:
- a main body;
- and
- a wet cleaning module arrangeable in the main body,
- wherein the wet cleaning module comprises:
- at least one wet pad, which is attachable to and detachable from under the main body, rotatable around a rotation axis;
- a lifting structure to support the at least one wet pad to enable a rotation of the at least one wet pad and a vertical movement of the at least one wet pad;
- and
- a driving unit configured to provide a rotational driving force to the lifting structure to enable the rotation of the at least one wet pad and the vertical movement of the at least one wet pad,
- the lifting structure comprises:
- a housing;
- a first bushing, to be fixed to an inside of the housing, configured to receive a rotational driving force from the driving unit while fixed to an inside of the housing;
- a second bushing configured to deliver, based on a rotation of the first bushing according to the rotational driving force from the driving unit, a rotational driving force of the first bushing to the at least one wet pad to enable the vertical movement and the rotation of the at least one wet pad;
- and
- a middle bushing, connectable between the first bushing and the second bushing, configured to enable a vertical movement and a rotation by the rotational driving force of the first bushing based on the rotation of the first bushing, and
- wherein, based on the rotation of the first bushing, the middle bushing moves vertically and rotates, and based on the middle bushing rotating, the second bushing moves vertically and rotates.
