Abstract
An electrostatic dust protection device comprises a blackboard eraser, a push button, a battery, soft cloth, a shell, a notch and an electrostatic generator, wherein the push button is arranged in the shell; the soft cloth is wrapped on the cleaning bristles of the blackboard eraser; the electrostatic generator is arranged below the push button; the notch is arranged on the push button; the battery is connected with the electrostatic generator and the push button in series; the positive electrode of the battery is connected with one end of the push button, the other end of the push button is connected with the positive electrode of the electrostatic generator, and the negative electrode of the electrostatic generator is connected with the negative electrode of the battery; and the soft cloth is electriferous and is connected with the electrostatic generator. When cleaning the blackboard, the notch is pressed to touch the push button so that the electrostatic generator can be started, the electrostatic generator conveys the static electricity onto the soft cloth, and the chalk dust generated by cleaning the blackboard is absorbed by utilizing the static electricity. Because the electrostatic generator is arranged on the electrostatic dust protection device, the utility model can effectively absorb the chalk dust generated by cleaning the blackboard, and thereby the environment and the health of teachers and students are protected. The electrostatic dust protection device has low cost and simple operation, and is particularly suitable for classroom teaching.
Description
Technical field
The utility model relates to a kind of dust guard, is specifically related to a kind of electrostatic dust prevention device.
Background technology
At present, a kind of dust-proof blackboard eraser of prior art, this dust-proof blackboard eraser is made up of dust-collecting box and blackboard eraser, dust-collecting box is a rectangle box that the below is uncovered, top panel middle part at dust-collecting box, leave the rectangular aperture that a size is slightly larger than the blackboard eraser frame, the friction tight one that is mounted to of four limits of opening and blackboard eraser frame, on the following peripheral of dust collecting opening, the flexible rings that one circle flexible material is made is housed, so that the raising dust collection effect, the wiping dirt face of blackboard eraser should equal and be slightly less than the following peripheral of dust-collecting box.
The dust-proof blackboard eraser that also has a kind of prior art, it mainly is made up of housing, wiper and dust box, feature is: housing, wiper and blackboard form the space of sealing basically, when erasing the board, the chalk powder of being wiped is limited in this space basically, because the effect chalk powder of gravity falls into the dust box.
The shortcoming of the dust-proof blackboard eraser of this prior art is:
1, the dust-proof blackboard eraser of this prior art can not effectively be removed chalk dust owing to be not provided with electrostatic generator.
2, the dust-proof blackboard eraser cost height of this prior art, poor effect.
The utility model content
The purpose of this utility model provides a kind of electrostatic dust prevention device, and it can utilize electrostatic generator effectively to absorb the chalk dust that produces when erasing the board, protection environment and teachers and students' health.
The purpose of the utility model electrostatic dust prevention device is achieved through the following technical solutions: a kind of electrostatic dust prevention device comprises blackboard eraser; Also comprise button, battery, soft cloth, shell, notch and electrostatic generator.
Described button setting in the enclosure.
Described soft cloth is coated in the snag of blackboard eraser.
Described electrostatic generator is arranged on the button below.
Described notch is arranged on the button.
Described battery is connected in series with electrostatic generator and button.

Above-mentioned electrostatic dust prevention device, wherein, the positive pole of described battery is connected with an end of button, and the other end of button is connected with the positive pole of electrostatic generator, and the negative pole of electrostatic generator is connected with the negative pole of battery.
Above-mentioned electrostatic dust prevention device, wherein, described soft cloth is electrifiable soft cloth, is connected with electrostatic generator.
The utility model electrostatic dust prevention device makes it compared with prior art owing to adopted such scheme, has following advantage and good effect:
1, the utility model electrostatic dust prevention device can effectively absorb the chalk dust that produces when erasing the board owing to be provided with electrostatic generator, protection environment and teachers and students' health.
2, the utility model electrostatic dust prevention installation cost is low, and is easy to operate, especially is fit to classroom instruction and uses.
Description of drawings
Fig. 1 is the cutaway view of the utility model electrostatic dust prevention device.
Fig. 2 is the circuit theory diagrams of the utility model electrostatic dust prevention device.
The specific embodiment
See also shown in the accompanying drawing 1, the utility model electrostatic dust prevention device comprises blackboard eraser 1, button 2, battery 3, soft cloth 4, shell 5, notch 6 and electrostatic generator 7; Button 2 is arranged in the shell 5, shell 5 can adopt the non-conductive shell of plastics, soft cloth 4 is coated in the snag of blackboard eraser 1, electrostatic generator 7 is arranged on button 2 belows, notch 6 is arranged on the button 2, battery 3 is connected in series with electrostatic generator 7 and button 2, the positive pole of battery 3 is connected with an end of button 2, the other end of button 2 is connected with the positive pole of electrostatic generator 7, the negative pole of electrostatic generator 7 is connected with the negative pole of battery 3, and soft cloth 4 is electrifiable soft cloths, is connected with electrostatic generator 7, battery 3 can adopt button cell, and button 2 can adopt actuation button.
The using method of the utility model electrostatic dust prevention device is, when erasing the board, notch 6 pressurized actuation button 2 are opened electrostatic generator 7, and electrostatic generator 7 passes to static on the soft cloth 4, utilizes static that the chalk dust that produces is absorbed when erasing the board.
In sum, the utility model electrostatic dust prevention device can effectively absorb the chalk dust that produces when erasing the board owing to be provided with electrostatic generator, protection environment and teachers and students' health; The utility model electrostatic dust prevention installation cost is low, and is easy to operate, especially is fit to classroom instruction and uses.
