Abstract

A self-wringing mop is disclosed that comprises a handle, a mounting support forming an axis of rotation, wherein the mounting support is connected with the handle, a cleaning portion connected with the mounting support in such a manner that the cleaning portion is rotatable about the axis, and a pressing member connected with the handle, wherein the pressing member engages with the cleaning portion to inhibit rotation of the cleaning portion.

Claims

1. A mop comprising:

a handle;

a mounting support forming an axis of rotation, wherein the mounting support is connected with the handle;

a cleaning portion connected with the mounting support in such a manner that the cleaning portion is rotatable about the axis; and

a pressing member connected with the handle, wherein the pressing member engages with the cleaning portion to inhibit rotation of the cleaning portion.

2. The mop of claim 1, wherein the pressing member is movably connected with the handled for engaging the pressing member with the cleaning portion.

3. The mop of claim 1, wherein the mounting support is movably connected with the handle for engaging the pressing member with the cleaning portion.

4. The mop of claim 1, wherein the pressing member engages against the periphery of the cleaning portion.

5. The mop of claim 1, wherein the pressing member engages across the entire cleaning portion.

6. The mop according to claim 1, wherein the pressing member comprises a first pressing member and a second pressing member with a predetermined space therebetween, the space having a width less than a width of the cleaning portion in a direction perpendicular to the rotation axis of the cleaning portion.

7. The mop according to claim 6, wherein each of the first pressing member and the second pressing member comprises a roller.

8. The mop according to claim 6 further comprising a pressing member connecting part including a first pressing member connecting part and a second pressing member connecting part, the first pressing member connecting part and the second pressing member connecting part respectively having ends mounted through a sleeve to the handle and the other ends respectively connected with the first pressing member and the second pressing member.

9. The mop according to claim 8, wherein:

a space is formed between the first pressing member connecting part and the second pressing member connecting part; and

the mounting support includes a first portion extending substantially parallel to the rotation axis of the cleaning portion and located between the first pressing member connecting part and the second pressing member connecting part, second portions respectively extending from two ends of the first portion toward a side of the cleaning portion, and a cleaning portion shaft coupled to ends of the second portions on which the cleaning portion is rotatably mounted.

10. The mop according to claim 6, wherein a locking part is formed on a surface of at least one of the first pressing member connecting part and the second pressing member connecting part, the surface facing the first portion of the cleaning portion mounting support;

and a latching part is formed at a portion of the first portion of the cleaning portion mounting support corresponding to the locking part so as to lock the cleaning portion in the stationary state or the state of rotation with a rotational resistance.
