Abstract

The utility model relates to an eraser. A piece of sponge is arranged on the upper surface of a panel of the eraser, a spillway hole is arranged on the panel, a spillway hole baffle is arranged on the bottom surface of the panel, and a water storage box is arranged below the panel. When the eraser is used, the sponge is pressed, so that a boss going deep into the sponge is extruded to separate the spillway hole from the panel, and water in the water storage box can soak the sponge through the spillway hole, therefore, when the eraser is used for cleaning a blackboard, wiped dust can be absorbed on the wet sponge, thereby realizing the function of absorbing the dust.

Description

A kind of blackboard eraser

Technical field

The utility model relates to a kind of blackboard eraser, has a kind of blackboard eraser of pick-up performance specifically, belongs to the teaching aid field.

Background technology

Blackboard eraser is one of realia indispensable in the classroom; Teacher writes on black and white with chalk, need use blackboard eraser and remove the marking of staying on the blackboard of writing, but existing blackboard eraser is exactly common hairbrush; Utilize friction that the chalk marking that book writes on the blackboard is swept down; The granule dust that will make like this flies upward everywhere, and not only bad for the maintenance of health, the chalk particle sucks the damage that human body also can cause health.

Summary of the invention

The utility model technical problem to be solved provides a kind of blackboard eraser, can be effectively with the following minute dust collection of blackboard eraser cleaning.

For addressing the above problem, the utility model adopts following technical scheme:

A kind of blackboard eraser, the panel upper surface of said blackboard eraser is provided with sponge, it is characterized in that: said panel is provided with spillway hole, and the bottom surface of said panel is provided with the spillway hole baffle plate, and said panel below is provided with storage box.

Below be further improvement to such scheme:

The plate face of said spillway hole baffle plate one end is provided with projection, and said projection passes panel and is deep in the sponge, and the panel of the said spillway hole baffle plate other end is fixedly installed on the below of panel.

The utility model compared with prior art has following characteristics: simple in structure, easy to use; Push sponge during use, make the projection that is deep in the sponge receive extruding, thereby make the spillway hole baffle plate separate with panel; Make the water in the storage box soak sponge through spillway hole; When the cleaning blackboard, just can the dust under the wiping be adsorbed onto on the moistening sponge like this, thereby play the effect of adsorbing dust.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Accompanying drawing 2 is the structural representation of panel among the utility model embodiment.

Among the figure:

The 1-panel, 2-sponge, 3-spillway hole, 4-storage box, 5-spillway hole baffle plate, 6-projection.

The specific embodiment

Embodiment, like Fig. 1, shown in Figure 2, a kind of blackboard eraser; Panel 1 upper surface of said blackboard eraser is provided with sponge 2, and said panel 1 is provided with spillway hole 3, and the bottom surface of said panel 1 is provided with spillway hole baffle plate 5; Said panel 1 below is provided with storage box 4; The plate face of said spillway hole baffle plate 5 one ends is provided with projection 6, and said projection 6 passes panel 1 and is deep in the sponge 2, and the panel of said spillway hole baffle plate 5 other ends is fixedly installed on the below of panel 1.

Push sponge 2 during use; Make the projection 6 that is deep in the sponge 2 receive extruding; Thereby make spillway hole baffle plate 5 separate, make that the water in the storage box 4 soaks sponge 2 through spillway hole 3, like this when the cleaning blackboard with panel 1; Just can the dust under the wiping be adsorbed onto on the moistening sponge, thereby play the effect of adsorbing dust.
