Further, described spacer mechanism includes several baffle plates and several hollow out through holes, described baffle plate and described hollow out through hole interval and arranges, and the size of described baffle plate and described hollow out through hole is all higher than the size of string permeability hole.
Further, described spacer mechanism is provided with contiguous block towards the side of described hollow out chute, and described pushing block is connected by connecting rod with described contiguous block, and the size of described contiguous block and described pushing block is all higher than described chute.
Further, described contiguous block and described pushing block are equipped with sealing gasket towards the end face of described hollow out chute.
Further, described containing liquid chamber be arranged over filling opening, described filling opening is provided with upper cover.
Further, described containing liquid chamber be arranged over penholder groove.
Further, described blackboard eraser adopts sponge to make.
Compared with prior art, the utility model has the advantages that:
Adopt the technical solution of the utility model, ethanol is injected in containing liquid chamber, when needs wiping blank, promoting pushing block to make permeability hole unimpeded, namely the ethanol in containing liquid chamber flow on blackboard eraser through permeability hole, namely can be used for wiping blank, promote pushing block to make spacer mechanism be blocked by permeability hole when using blackboard eraser, namely ethanol be mothballed in containing liquid chamber, it is simple to use during wiping blank next time, this whiteboard eraser is safe and convenient to use, is with a wide range of applications.
