Moistening and cleaning device for blackboard sponges. The subject of the present invention is a Befeuclitungs- and Reinigungsvorrich device for blackboard sponges, which consists of a \ Vasserkasten with springs suspended up and down sponge carrier.
In the accompanying drawings, the subject matter of the invention is shown in an exemplary embodiment, namely: Fig. 1 is a front view of the device with partial section.
Fig.? a top view of the device. The device shown has a water tank a (Fig. 1). Two eyelets are provided on the rear wall for attaching them to the wall. In the water box there is a sponge carrier b made of galvanized iron wire mesh, which is suspended by means of decorative springs c on the side walls of the box on small eyelets. The sponge d comes to lie on this sponge carrier. For use, the V-cup box is filled with water until it reaches about 1 cm from the sponge support. The sponge is placed on the sponge carrier. Should the sponge be wetted.
A slight pressure on the same is sufficient, as the soft feathers give way and the sponge comes into contact with the water and holds water as required. When the sponge is removed, the springs return to their rest position. After using the sponge it is put back on the sponge carrier and cleaned by pressing it down several times.
The device described is particularly suitable for wetting the sponges, for loosening the accumulated chalk residues and for re-drying the sponge.
