Abstract
本实用新型公开了一种静电除尘黑板擦，包括盒体和嵌于盒体内的擦体，盒体沿横向设置出气管道，出口处设置喷吸式风扇；擦体的下部设置纤维质绒毛刷与纵横交叉的金属网线组成的复合毛刷层，并分散设置多个细小的吸尘管，上部设置有多个弯折的气流通道，与细小的吸尘管、出气管道相连通，气流通道中设置多个过滤网。本实用新型的静电除尘黑板擦，开始擦黑板时，复合毛刷层具有较强的吸附能力；同时，盒体两侧的喷吸式风扇工作，复合毛刷层吸附的粉尘，从细小的吸尘管进入弯折的气体通道中被内腔的石墨层吸附和经过滤网过滤后，洁静气体从出气管道出口，使用完毕后，可以将擦体取出，清洗后可重复使用。该黑板擦对粉尘吸附效率高、结构简单实用。
The utility model discloses an electrostatic dust removal blackboard eraser, which comprises a box body and an eraser embedded in the box body. The box body is provided with an air outlet pipe along the horizontal direction, and a spray-suction fan is arranged at the outlet; A composite brush layer composed of vertical and horizontal metal mesh wires, and a number of small dust suction pipes are scattered. Multiple filters. When the electrostatic dust removal blackboard eraser of the utility model starts to wipe the blackboard, the composite brush layer has strong adsorption capacity; at the same time, the suction fans on both sides of the box work, and the dust adsorbed by the composite brush layer After the dust tube enters the bent gas channel, it is absorbed by the graphite layer in the inner cavity and filtered by the filter, and the clean gas exits from the outlet pipe. After use, the wiper can be taken out, and it can be reused after cleaning. The blackboard eraser has high dust absorption efficiency and simple and practical structure.
Description
Technical field
The utility model relates to the teaching aid technical field, relates in particular to a kind ofly to carry out dust-removing blackboard eraser by Electrostatic Absorption.
Background technology
Blackboard and chalk are the most common, most popular educational aids, teacher is when teaching, wipe chalk dust with blackboard eraser, can produce very big chalk dust, pollute the air in the classroom, brought harm for student and teacher's health, so the dedusting function of blackboard eraser is very important, occur some in the market and can collect the blackboard eraser of chalk dust, but the defective that these blackboard eraser ubiquities complex structure, cost height, are not suitable for applying.
The utility model content
At above-mentioned defective, the utility model provides a kind of electrostatic precipitation blackboard eraser, and this wiping blackboard structure is simple, good dedusting effect, can prevent chalk dust harm teachers and students health.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of electrostatic precipitation blackboard eraser comprises the box body of being with groove and is embedded in the interior rub body of box body, described box body built-in power, and along the horizontally set outlet pipe, the outlet pipe exit arranges the spray-sucking type fan; The bottom of described rub body arranges cellulosic fine hair and brushes the compound hairbrush layer of forming with the mesh wire that intersects in length and breadth, compound hairbrush layer disperses to arrange a plurality of tiny sweep-up pipes, described rub body top is provided with the gas channel of a plurality of bendings, be connected with tiny sweep-up pipe, outlet pipe, a plurality of screen packs are set in the gas channel.
Further, described gas channel inwall arranges the good graphite linings of adsorptivity.
Further, the back of described box body arranges magnet arrangement, can be attached on the magnet board, the convenient use.
Electrostatic precipitation blackboard eraser of the present utility model, when beginning to erase the board, the power supply energising, dust can be brushed and be adsorbed by compound hairbrush layer by bristle, mesh wire as electrostatic generator is charged, mesh wire and bristle overlap and form compound hairbrush layer, and compound hairbrush layer has stronger adsorption capacity; Simultaneously, the spray-sucking type fan work of box body both sides, make gas channel and the outlet pipe of sweep-up pipe tiny in the compound hairbrush layer, bending form a dust sorption channel, the dust of compound hairbrush layer absorption, enter the gas passage of bending by the absorption of the graphite linings of inner chamber with after filtration behind the net filtration from tiny sweep-up pipe, clean pneumostatic body exports from outlet pipe, after finishing using, rub body can be taken out, it is reusable to clean the back.This blackboard eraser is to dust adsorption efficiency height, simple and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with specific embodiment.
As shown in Figure 1, electrostatic precipitation blackboard eraser of the present utility model comprises the box body 1 of being with groove and is embedded in the interior rub body 2 of box body, described box body 1 built-in power 3, and along horizontally set outlet pipe 4, outlet pipe 4 exits arrange spray-sucking type fan 5; The bottom of described rub body 2 arranges cellulosic fine hair and brushes the compound hairbrush layer of forming with the mesh wire that intersects in length and breadth 6, compound hairbrush layer 6 disperses to arrange a plurality of tiny sweep-up pipes 7, described rub body 2 tops are provided with the gas channel 8 of a plurality of bendings, be connected with tiny sweep-up pipe 7, outlet pipe 4, a plurality of screen packs 9 are set in the gas channel 8.
Described gas channel 8 inwalls arrange the good graphite linings of adsorptivity.
The back of described box body 1 arranges magnet arrangement, can be attached on the magnet board, the convenient use.
The above only is a kind of embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
