Self-wringing foam cotton mop with labor-saving wringing operation

A self-wringing foam cotton mop with a labor-saving wringing operation, the self-wringing foam cotton mop comprising a mop rod and a foam cotton head, wherein:

• the foam cotton head is rotatably connected to a bottom end of the mop rod;
• a wringing frame is disposed on the mop rod;
• during mopping, the foam cotton head is separated from the wringing frame;
• a squeezing mechanism capable of squeezing the foam cotton head entering the wringing frame is disposed on the wringing frame;
• a position of the squeezing mechanism is changeable, so that the position of the squeezing mechanism when the foam cotton head is moved upward relative to the wringing frame is different from the position of the squeezing mechanism when the foam cotton head is moved downward relative to the wringing frame;
• and
• a first amount of deformation generated by the foam cotton head during an upward movement of the foam cotton head relative to the wringing frame is greater than the second amount of deformation generated by the foam cotton head during a downward movement of the foam cotton head relative to the wringing frame.
