The present invention is a unique semi-automatic mop wringer. The mop wringer comprises a hollow housing vertically movably supported on a supporting structure by a suspension mechanism. The housing is engaged with the supporting structure through a rack-and-gear mechanism, so that a downward motion of the housing can be transmitted into the rotation of crank members which in turn drive a wringer roller to squeeze the mop against a wringer plate mounted inside the housing. A user can use the present invention mop wringer to wring a mop by placing the mop inside the housing, holding the mop holder and applying a downward force. The downward motion of the housing causes the wringer roller to move in a circular path to squeeze the mop against the wringer plate. When the user withdraws the downward force, the housing moves back upwardly to allow the user to repeat the process. When the wringer roller has completed the squeezing motion, the wringer roller can automatically complete the remaining portion of the circular path.

A semi-automatic mop wringer for wringing a mop that is attached to a mop handle through a mop holder, the mop wringer comprising: a. a housing having a main central compartment, a first side compartment and an opposite second side compartment, the main compartment being a wide hollow through compartment with an upper entrance and a lower outlet, the first and second side compartments being narrow hollow compartments with respective lower openings; b. a supporting structure having a first vertical stand and an opposite second vertical stand each including a rack with teeth, the first and second vertical stands extending into said first and second side compartments through their said lower openings respectively; c. said housing being suspended upon said supporting structure by spring suspension means and being able to move up and down; d. a first pinion wheel and a symmetric second pinion wheel rotatably mounted in said first and second side compartments respectively and engaged with said teeth of said rack of said first and second stands respectively, the downward movement of said housing causing said first and second pinion wheel to rotate in a first direction and the upward movement of said housing causing said first and second pinion wheel to rotate in an opposite second direction; e. a first spur gear and a symmetric second spur gear rotatably mounted in said first and second side compartments respectively and rotatably coupled with a pair of symmetric cranks, respectively, which support a wringer roller, the rotation of the first and second spur gears causing the roller to move in a circular path which includes a first half and a second half; f. a first pawl-ratchet mechanism for transmitting in one-way the rotation of said first and second pinion wheels to said first and second spur gears respectively, the first pawl-ratchet mechanism including a first moving pawl and a second moving pawl mounted on said first and second pinion wheels respectively, and a first small ratchet wheel and a symmetric second small ratchet wheel rotatably mounted in said first and second side compartments respectively, engaged with the first and second moving ratchet respectively and meshed with said first and second spur gears respectively, such that the rotation of said first and second pinion wheels in said first direction causes said first and second spur gears to rotate in said second direction, but the rotation of said first and second said pinion wheels in said second direction does not cause said first and second spur gears to rotate; g. a second pawl-ratchet mechanism for regulating the rotation of said first and second spur gears respectively, the second pawl-ratchet mechanism including a first stationary pawl and a second stationary pawl mounted to said housing and located in said first and second pinion wheels respectively, and a first large ratchet wheel and a symmetric second large ratchet wheel rotatably mounted in said first and second side compartments respectively and meshed with said first and second spur gears respectively, such that the first and second large ratchet wheels can only rotate one-way in said first direction, which prevents respectively said first and second spur gears to rotate in said first direction; h. said first and second large ratchet wheels being biased by spring biasing means for balancing said first and said second spur gears to allow said wringer roller to move intermittently as it moves in said first half of said circular path, and for driving said first and second spur gears to rotate in said second direction as said wringer roller moves into said second half of said circular path, which causes said wringer roller automatically to complete said second half of said circular path; i. a semi-circular wringer plate mounted in said main compartment for receiving said mop, the wringer plate circumscribing said first half of said circular path of said wringer roller and having a multiplicity of apertures for draining water; and j. receiving and supporting means located proximal to said entrance of said main compartment for receiving and supporting said mop holder; k. whereby a user can use said mop wringer to wring said mop by placing said mop into said main compartment, placing said mop holder onto said receiving and supporting means, holding said mop handle and applying a downward force to said mop handle, the downward movement of said housing causing said wringer roller to move in said first half of said circular path and squeeze said mop against said wringer plate, when the user withdraws the downward force, said housing will move back upwardly to allow the user to repeat the process, and when said wringer roller completes said first half of said circular path and moves into said second half of said circular path, said wringer roller automatically completes said second half of said circular path.
