Abstract
The utility model discloses a novel blackboard eraser which comprises a main board. The two sides of the main board are movably connected with eraser hair and a wet sponge block respectively. An elastic return water box is movably connected with the lower portion of one side, where the wet sponge block is arranged, of the main board. When the blackboard eraser is used, dust on the surface of a blackboard is got rid of through the eraser hair at first, then the sponge block is used for wiping dirty marks difficult to clear on the surface of the blackboard, water squeezed out of the wet sponge block falls into the elastic return water box below the main board when the wet sponge is used for wiping the blackboard, the elastic return water box can be dismantled at will if filled with the water and can be reinstalled on the main board of the blackboard to continued to be used after the water is dumped. Therefore, the problems that water is easily squeezed out, drips all around and influences normal teaching work when a wet eraser of an original dual-purpose blackboard eraser for wetting and drying is utilized are solved.
Description
Technical field
The utility model relates to a kind of study article field, especially a kind of novel blackboard eraser.
Background technology
Existing blackboard eraser is when blackboard wiping, can only wipe the blackboard surface dust, spot for some awkward cleanings just need to be come wiping with the wet rubbing on the Wet-dry blackboard eraser, but existing Wet-dry blackboard eraser, when wet rubbing uses, moisture is easy to be extruded, and the large-area surface that is dropped in blackboard then has a strong impact on the carrying out of normal teaching.
The utility model content
The utility model technical assignment is for above-mentioned technical deficiency, and a kind of novel blackboard eraser is provided.
The technical scheme that the utility model technical solution problem adopts is: novel blackboard eraser, comprise mainboard, and the both sides of described mainboard are connected with respectively snag and wet sponge piece, are connected with elasticity backwater box in the underside of the mainboard that is provided with wet sponge piece one side.
The beneficial effect that the utility model can bring is: efficiently solve original Wet-dry blackboard eraser, in the wet rubbing use procedure, moisture easily is extruded out, drips the impact on normal teaching everywhere.
Description of drawings
Fig. 1, the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done following detailed description:
As shown in Figure 1, the utility model discloses a kind of novel blackboard eraser, comprise mainboard 1, the both sides of described mainboard 1 are connected with respectively snag 2 and wet sponge piece 3, are connected with elasticity backwater box 4 in the underside of the mainboard 1 that is provided with wet sponge piece 3 one sides.
During use, dispose first the dust on blackboard surface with snag 2, then come the spot of those awkward cleanings of blackboard wiping surface with wet sponge piece 3, when coming blackboard wiping with wet sponge piece 3,3 li moisture that are extruded out of wet sponge piece fall in the elasticity backwater box 4 of mainboard 1 below, if water has been expired in the 4 interior storages of elasticity backwater box, can arbitrarily it be pulled down, outwell and continue on the mainboard 1 that is installed in again blackboard eraser after the water to use.So just solved original Wet-dry blackboard eraser, in the wet rubbing use procedure, moisture easily is extruded out, drips the impact on normal teaching everywhere.
