The utility model is characterized in that the water absorption sponge is arranged inside the cover of the blackboard eraser, the whole body of the water absorption sponge is arranged over the upper surface of the clapboard, a hole on the clapboard is fabricated through mechanic processing, the lower surface of the clapboard is connected with the cloth of the blackboard eraser, and that the upper end of the exterior surface of the cloth of the blackboard eraser is connected with the lower end of the exterior surface of the cover of the blackboard eraser.

Description

Multifunctional blackboard eraser

(1) technical field:

The utility model relates to multifunctional blackboard eraser, divides the technical field of big group of cleaning device belonging to blackboard or slabstone by International Patent Classification (IPC) (IPC).

(2) background technology:

At present, existing technology with big group of the cleaning device about blackboard or slabstone that once had need all be done very fruitful effort to multifunctional blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Wang Juncheng, Granted publication number is CN2235905Y, China Patent No. (ZL) is: No. 95225177.9 utility model title is the utility model patent of " dust absorption blackboard eraser ", the technical scheme that is adopted, big group of technical elements of cleaning device at blackboard or slabstone is a routine of great value invention, and it has solved technical problem easy to use effectively.But still have some deficits, it also is difficult to solve dustproof, fixing technical problem.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of multifunctional blackboard eraser.Dustproof to solve, fixing technical problem.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: multifunctional blackboard eraser of the present utility model mainly is made of blackboard eraser lid, water-absorbing sponge, hole, dividing plate, fixed band, blackboard wiper.

In shape, structure and combination thereof, the total essential features of multifunctional blackboard eraser of the present utility model and immediate prior art is: the overall fixed of blackboard wiper is connected the lower end of blackboard eraser lid, be combined into the integrative-structure of blackboard eraser shape, function has been the effect of blackboard eraser.In shape, structure and combination thereof, the multifunctional blackboard eraser of the present utility model technical characterictic different with immediate prior art is: water-absorbing sponge is placed on the inside of blackboard eraser lid, the integral body of water-absorbing sponge is placed on the upper surface of dividing plate, dividing plate is processed pore-forming with mechanical means, the dividing plate lower surface links to each other with the blackboard wiper, be combined into the combining structure of blackboard eraser shape, function has been the dustproof effect.The outer surface upper end of blackboard wiper is bonded in the outer surface lower end that blackboard eraser covers with fixed band, is combined into the integrative-structure of blackboard eraser shape, and function has been fixing effect.So just reached dustproof, the fixing purpose of multifunctional blackboard eraser of the present utility model.

The beneficial effect of the multifunctional blackboard eraser of utility model is that the utility model is that dustproof, the fixing technical scheme that technical problem adopted of solution has been compared two place's advantage and improvement with existing technology with big group of the cleaning device about blackboard or slabstone that once had:

First, be placed on the inside that blackboard eraser covers owing to designed water-absorbing sponge in the technical scheme of multifunctional blackboard eraser of the present utility model, the integral body of water-absorbing sponge is placed on the upper surface of dividing plate, dividing plate is processed pore-forming with mechanical means, the dividing plate lower surface links to each other with the blackboard wiper, be combined into the combining structure of blackboard eraser shape, so easier solution dustproof technical problem.

Second, because the outer surface upper end of having designed the blackboard wiper in the technical scheme of multifunctional blackboard eraser of the present utility model is bonded in the outer surface lower end of blackboard eraser lid with fixed band, be combined into the integrative-structure of blackboard eraser shape, so the fixing technical problem of easier solution.

(4) description of drawings:

Accompanying drawing provides the structural representation of multifunctional blackboard eraser of the present utility model:

Fig. 1: the overall structure schematic diagram that is multifunctional blackboard eraser of the present utility model;

The label declaration at each position in the schematic diagram:

1 blackboard eraser covers 2 water-absorbing sponges, 3 holes, 4 dividing plates, 5 fixed bands, 6 blackboard wipers

(5) specific embodiment:

Below in conjunction with accompanying drawing, be that the optimal way that realization solves the technical scheme that dustproof, fixing technical problem takes is described further to multifunctional blackboard eraser of the present utility model:

Its static structure: see also accompanying drawing: as shown in the figure, multifunctional blackboard eraser of the present utility model mainly is made of blackboard eraser lid 1, water-absorbing sponge 2, hole 3, dividing plate 4, fixed band 5, blackboard wiper 6.Its major part water-absorbing sponge 2, fixed band 5, blackboard wiper 6 are selected for use by market.Its blackboard eraser lid 1 is a rectangular shape, is material with plastics, through the machining manufacturing.Its dividing plate 4 is rectangular shapes, is material with plastics, through the machining manufacturing.

In shape, structure and combination thereof, the total essential features of multifunctional blackboard eraser of the present utility model and immediate prior art is: the overall fixed of blackboard wiper 6 is connected the lower end of blackboard eraser lid 1, be combined into the integrative-structure of blackboard eraser shape, function has been the effect of blackboard eraser.In shape, structure and combination thereof, the multifunctional blackboard eraser of the present utility model technical characterictic different with immediate prior art is: water-absorbing sponge 2 is placed on the inside of blackboard eraser lid 1, the integral body of water-absorbing sponge 2 is placed on the upper surface of dividing plate 4, dividing plate 4 usefulness mechanical means processing pore-forming 3, dividing plate 4 lower surfaces link to each other with blackboard wiper 6, be combined into the combining structure of blackboard eraser shape, function has been the dustproof effect.The outer surface upper end of blackboard wiper 6 is bonded in blackboard eraser with fixed band 5 and covers 1 outer surface lower end, is combined into the integrative-structure of blackboard eraser shape, and function has been fixing effect.

Below by using method, further set forth multifunctional blackboard eraser dynamic structure relation of the present utility model: in use, in the time of the needs dustproof, according to physical principle, at first with dividing plate 4 processing pore-formings 3, be placed on water-absorbing sponge 2 on the dividing plate 4 and the last blackboard eraser lid 1 of cover, dividing plate 4 lower surfaces link to each other with blackboard wiper 6, then when erasing the board, under the effect of gravity, water in the water-absorbing sponge 2 flows in the blackboard wiper 6 by the hole 3 of dividing plate 4, makes blackboard wiper 6 moistening, thereby finishes the dustproof task.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of blackboard eraser factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of multifunctional blackboard eraser of the present utility model better with the demand of supply educational circles.
