Mop handle with improved water flow control

A hollow mop handle having a holding portion with an internal partition having an opening for flow of liquid through said holding portion, a stopper selectively movable between three distinct positions wherein said stopper fully blocks, partially blocks, and fully unblocks flow through said opening, respectively, and manually operable means for effecting movement of said stopper between said three positions, comprising:

• a) a total of three detent portions having spaced, parallel axes extending from said stopper;
• and
• b) a total of three recesses formed in said internal partition, said recesses being cooperatively shaped and spaced to receive said detent portions as said stopper is moved between said three positions, a first of said detents being engaged in a first of said recesses when said stopper fully blocks said opening, a said first and a second of said detents being engaged in a second and in said first recess, respectively, when said stopper partially blocks said opening, and said first and second and a third of said detents being engaged in a third and in said first and second recesses, respectively, when said stopper fully unblocks said opening.
