BEST MODE FOR CARRYING OUT THE INVENTION The opposed surfaces of the present invention, which are relatively rotated, have one fixed and the other rotated.
In some cases, both of them rotate and the rotational speeds thereof are different, so that a relative rotational movement is generated on the facing surface. Also, the water absorbing material on the facing surface is only in one direction of the facing surface, the other is a non-water absorbing material such as brush bristles, the two facing surfaces are both water absorbing, and the combination is There is. One of the opposing surfaces of the present invention is provided as a fixed surface, the other is provided on a rotating disk in an annular shape, the center of the fixed surface is opened, coins are inserted into the center of the rotating disk from the opening, and the coin is fixed on the fixed surface. It is preferable to allow the centrifugal force to pass between the rotating disk and the gap between the rotating disks because the object can be achieved with a simple structure. The shape of the rotating opposing surface may be a disk or a cone that is inclined downward. Examples of the water-absorbing material of the present invention include a water-absorbing material such as a sponge, or a material containing a water-absorbing cloth, woven fabric, or a chemical or polymer water-absorbing agent.
The water-absorbing surface is preferably a hollow space structure such as a sponge or a continuous porous structure in order to facilitate the movement of the absorbed water by the centrifugal force, the inclination, and the negative suction force of the pump. It is effective to combine the suction power of the pump as required.
