Abstract
The utility model discloses a static electricity dust removal blackboard eraser which comprises an eraser body and an eraser body installation box. The static electricity dust removal blackboard eraser further comprises an electrostatic generator arranged in the eraser body installation box. Electrostatic generation electrodes of the electrostatic generator are contacted with the eraser body. When the static electricity dust removal blackboard eraser is used, the electrostatic generator generates static electricity, the eraser body of the blackboard eraser is enabled to have static electricity, after chalk marks are erased by the eraser body, residual chalk dust can be absorbed, and chalk dust removal is achieved effectively, the chalk dust is prevented from generating dust pollution, classroom environment can be effectively improved, and health of teachers and students is guaranteed.
Description
Technical field
The utility model relates to the teaching appurtenance, particularly a kind of blackboard eraser.
Background technology
Existing blackboard eraser general only by felt as brush body, can wipe chalk writing well, but behind the chalk writing of wiping on the blackboard, can not thoroughly remove remaining chalk dust, dust pollution is more serious, this has just threatened teacher and classmate's health.
For above-mentioned deficiency, need existing blackboard eraser is improved, make its function that not only has the erasing chalk writing, can also remove chalk dust, reduce the dust pollution in the classroom.
The utility model content
In view of this, the utility model provides a kind of electrostatic dedusting blackboard eraser, is provided with electrostatic generator on this blackboard eraser, the technical problem that can not effectively remove remaining chalk dust to solve existing blackboard eraser.
The utility model solves the problems of the technologies described above by following technological means:
Electrostatic dedusting blackboard eraser of the present utility model comprises brush body and brush body mounting box, also comprises the electrostatic generator that is arranged in the brush body mounting box, and the generation of static electricity electrode of described electrostatic generator contacts with brush body.
Further, described brush body mounting box bottom is provided for holding the rectangular cavities of brush body, and described generation of static electricity electrode is arranged at the rectangular cavities bottom.
Further, described generation of static electricity electrode is at least two, and is uniformly distributed in the rectangular cavities bottom.
Further, also comprise the electrostatic generator battery, described electrostatic generator battery is positioned in the brush body mounting box.
Further, be provided with electrostatic generator charge port and electrostatic generator shift knob on the described brush body mounting box.
The beneficial effects of the utility model: electrostatic dedusting blackboard eraser of the present utility model, comprise brush body and brush body mounting box, also comprise the electrostatic generator that is arranged in the brush body mounting box, the generation of static electricity electrode of described electrostatic generator contacts with brush body, during use, electrostatic generator produces static, make the brush body of blackboard eraser with static, brush body is behind the erasing chalk writing, the chalk dust of adsorbable remnants is realized the effective removing to chalk dust, avoids chalk dust to produce dust pollution, can effectively improve classroom environment, ensure that teachers and students are healthy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below with reference to accompanying drawing the utility model is elaborated, as shown in the figure: the electrostatic dedusting blackboard eraser of the present embodiment, comprise brush body 1 and brush body mounting box 2, also comprise the electrostatic generator 3 that is arranged in the brush body mounting box 2, the generation of static electricity electrode 4 of described electrostatic generator 3 contacts with brush body 1, electrostatic generator produces static, static is discharged on the brush body, during use, because brush body is with static, brush body is energy automatic absorbing chalk dust behind the erasing chalk writing, reduces airborne dust, effectively improves classroom environment.
In the present embodiment, described brush body mounting box 2 bottoms are provided for holding the rectangular cavities of brush body 1, and described generation of static electricity electrode 4 is arranged at the rectangular cavities bottom, and is simple in structure, is convenient to dismounting.
In the present embodiment, described generation of static electricity electrode 4 is at least two, and is uniformly distributed in the rectangular cavities bottom, adopts a plurality of electrodes can make the brush body each several part all charged, and adsorption effect is better, and dedusting is more thorough.
In the present embodiment, also comprise electrostatic generator battery 5, described electrostatic generator battery 5 is positioned in the brush body mounting box 2, and is simple and compact for structure, and is difficult for losing and damaging.
In the present embodiment, be provided with electrostatic generator charge port 2a and electrostatic generator shift knob 2b on the described brush body mounting box 2, can adopt rechargeable battery, charge by charge port, avoiding producing waste battery pollutes, start and close by switch control electrostatic generator, can use as required, avoid causing waste of energy.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
