Abstract

The utility model relates to an electrostatic type blackboard eraser which can effectively adsorb dust and keep the surface of a blackboard clean. The electrostatic type blackboard eraser comprises a blackboard eraser, wherein the inside of the blackboard eraser is a cavity in which an electrostatic generator is arranged, the back of the blackboard eraser can be provided with a battery and controls the on-off of the electrostatic generator through wires and a switch, and a dust receiving box is arranged on the bottom of the blackboard eraser. The blackboard eraser has the advantages that: 1. the blackboard eraser can effectively adsorb the dust and prevent the dust from flying all around; 2. the blackboard eraser can ensure the cleanness of surface of the blackboard and save the clean-up time; and 3. the blackboard is simple and practical in structure and low in manufacturing cost.

Description

Electrostatic blackboard eraser

Technical field

The utility model relates to a kind ofly can effectively absorb dust, keeps the electrostatic blackboard eraser of blackboard eraser cleaning surfaces, belongs to blackboard eraser and makes the field.

Background technology

The present blackboard eraser that uses in the school, structure is very simple, and its not enough point is: a dust from flying of usually doing when being to use, cause the user then and suck a large amount of dust with the people of blackboard close together, people healthy caused threat.The 2nd, a lot of dust are piled up on the surface of blackboard eraser easily, and cleaning is got up neither be very convenient, both time-consuming, again effort.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, design and a kind ofly can effectively absorb dust, keep the electrostatic blackboard eraser of blackboard eraser cleaning surfaces.

Design: to achieve these goals.1, in being the blackboard eraser of cavity body electrostatic generator being housed, and controlling the design of its running by switch and lead, is one of technical characterictic of the present utility model.The purpose of doing like this is: when loading onto battery to blackboard eraser, just can be by the through and off of switch and lead control electrostatic generator, when opening electrostatic generator, dust just enters into inside from the blackboard eraser surface, guaranteed the cleaning on blackboard eraser surface, also made dust be able to fly upward no longer everywhere.2, the design of ash accepting box being housed in the blackboard eraser bottom is two of a technical characterictic of the present utility model.The purpose of doing like this is: when dust enters blackboard eraser inside, just directly enter in the ash accepting box.When ash accepting box is full, blackboard eraser is opened, then with its taking-up, and clean.

Technical scheme: electrostatic blackboard eraser, it comprises blackboard eraser, blackboard eraser inside is cavity body, is equipped with electrostatic generator, but blackboard eraser back packed battery and the on-off by lead and switch control electrostatic generator, ash accepting box is arranged at the blackboard eraser bottom.

The utility model is compared with background technology, and the one, can effectively absorb dust, prevent that it from flying upward everywhere; The 2nd, guaranteed the cleaning on blackboard eraser surface, can save cleaning time; The 3rd, simple in structure, practical, low cost of manufacture.

Description of drawings

Fig. 1 is the structural representation of electrostatic blackboard eraser.

The specific embodiment:

Embodiment 1: with reference to Fig. 1, and electrostatic blackboard eraser, it comprises blackboard eraser 1, blackboard eraser 1 inside is cavity body, be equipped with electrostatic generator 2, but blackboard eraser 1 back packed battery 3 and the on-off by lead and switch 5 control electrostatic generators 2, and ash accepting box 4 is arranged at blackboard eraser 1 bottom.Blackboard eraser 1 wiping face is poroid through-hole structure.Electrostatic generator 2 is connected with battery tray by lead and switch 5, and battery 3 is arranged in the battery tray, and ash accepting box 4 is positioned at electrostatic generator 2 lower zones.When dust enters blackboard eraser 1 inside, just directly enter in the ash accepting box 4.

What need understand is; though above-mentioned fact Example is to the utility model detailed text description of contrasting; but these text descriptions; it is simple description to the utility model mentality of designing; rather than to the restriction of mentality of designing of the present utility model; any combination, increase or modification that is no more than the utility model mentality of designing all falls in the protection domain of the present utility model.
