Abstract
The utility model relates to one can not cause air-polluting electrostatic blackboard eraser.Comprise: vibration source and spring button, wherein, cap portion is made by electrostatic blackboard eraser rubber, the inside of lid contains a vibration source, and the material of the wiping of blackboard eraser is terylene, and intermediate groove is spring button, for fixed black blackboard eraser and blackboard eraser box, and connection circuit.
Description
Technical field
The present invention relates to a kind of educational aid, particularly relate to a kind of electrostatic blackboard eraser.
Background technology
At present, the problem that on market, the ubiquitous dust of blackboard eraser is large.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of electrostatic blackboard eraser of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide and a kind of there is two-sided electrostatic blackboard eraser.
Electrostatic blackboard eraser of the present invention, comprise: vibration source and spring button, wherein, cap portion is made by electrostatic blackboard eraser rubber, the inside of lid contains a vibration source, and the material of the wiping of blackboard eraser is terylene, and intermediate groove is spring button, for fixed black blackboard eraser and blackboard eraser box, and connection circuit.
Further, also comprise: the box of electrostatic blackboard eraser, there is individual groove the centre of the box of electrostatic blackboard eraser, groove two ends are electrodes, an outstanding little button of going to the bottom is spring button, cassette interior contains a dead circuit and a battery grooves, and whole box is adopted made of plastic.。
By such scheme, the present invention at least has the following advantages:
This product environmental protection, can not cause air pollution, decreases the injury to user's health.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of electrostatic blackboard eraser of the present invention;
Fig. 2 is the structural representation of electrostatic blackboard eraser box of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Shown in Figure 1, a kind of electrostatic blackboard eraser, comprising: 1, vibration source, 2, spring button, wherein, cap portion is made by electrostatic blackboard eraser rubber, and the inside of lid contains a vibration source 1, and the part of the wiping of blackboard eraser is owing to considering that cost performance is high, terylene is adopted to do, intermediate groove is spring button, and effect is for fixed black blackboard eraser and blackboard eraser box, and connection circuit.
Shown in Figure 2, a kind of box of electrostatic blackboard eraser, there is individual groove the centre of whole box, and groove two ends are electrodes 3, and an outstanding little button of going to the bottom is spring button 2.Cassette interior contains a dead circuit 4 and a battery grooves.Whole box is adopted made of plastic.
Operation principle of the present invention is as follows: this electrostatic blackboard eraser is powered with the battery of 2 joint 1.5v, and its energising can produce positive and negative charge, and chalk dust can be attracted to come off.The vibration source of blackboard eraser can vibrate simultaneously, and dual-use function makes more chalk dust drop, and can process the chalk dust totally depended on largely, alleviate the pollution level of environment, chalk dust is concentrated and comes off in box, finally focus on, time saving and energy saving.The material cost performance that this product adopts is high, blackboard eraser wiping part mainly adopts terylene, and it easily adsorbs a large amount of chalk dust, can reach a good treatment effect, thus the impact greatly reduced classroom environment, allow student and teacher have a good teaching environment.Blackboard eraser cover part adopts rubber, and rubber has good shock-absorbing function, and both combine, and can reach good effect.In addition, this product safety coefficient is high, easily processes, on year-on-year basis like product, price material benefit, and modern design is easy and simple to handle, and adopt new technology, increase bright spot, commercially having larger prospect, is a good product.This works cost performance is higher, practical, price is economical, the ability of absorption chalk dust is strong, and 664 adopt new technology, have certain uniqueness, and production development prospect is better, and contrast like product, adopt terylene, elastomeric material, has certain breakthrough and innovation.In addition, this product environmental protection, can not cause air pollution, decreases the injury to user's health.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
