Draining roller

Abstract

The present invention relates to an improved structure of a spiral draining roller, characterized in that a plurality of interlaced diagonal partition blocks, and having a design of spiral stairway draining grooves. By the simultaneous rolling of both the front and rear rollers while squeezing the water absorbing foam, drainage is provided for the dirty water to flow outwards towards either side of the grooves. In doing so, it further increases the effect of draining the dirty water by the left and right wings simultaneously and completely.

I claim:  
     
         1 . An improved structure of a spiral draining roller, comprising a U-shaped base disposed at the front end of a hold rod of a mop, and a roller being pivotally coupled between the bases, and a second base further comprises a water absorbing foam, and a pulling rod being disposed on both sides at the top edge of the foam, and the pulling rod passes through the base and pivotally coupled to a pulling handle on the holding rod, characterized in that: 
 a plurality of partition blocks are disposed on the protruded surface of said roller rod thereby forming a spiral draining groove, such that by means of squeezing the water absorbing form on the front and the rear end of the drainage roller, it provides a way of completely draining the dirty water through the water draining grooves towards both sides of the foam.    
     
     
         2 . The improved structure of a spiral draining roller, wherein said partition block on the surface of the roller is inclined with an angle or in the shape of letter “S” for squeezing the water absorbing foam of the roller to the utmost rear end and being attached to its original position on its return trip in order to fully squeeze the dirt away from the foam.
