Description

Automatically inhale dust ash formula blackboard eraser

Technical field

The utility model relates to a kind of blackboard eraser, especially a kind of automatic suction dust ash formula blackboard eraser.

Background technology

Blackboard brush is a kind of teaching appurtenance, still generally uses in teaching process so far.Blackboard brush in the market generally is made of plastics or iron shell parcel monoblock bristle, in order to wipe the letter written with chalk on the blackboard, blackboard is returned to write preceding state.

Use chalk after writing on the blackboard, when erasing the board with traditional blackboard eraser again, can cause dust from flying, and the dust that flies upward can damage, suck dust for a long time student and teacher's psychosomatic health very unfavorable all to human body.The structure that traditional blackboard is wiped generally comprises wipes head and wipes fixed head two parts, and not only kind is single, and function is simple, can only wipe dust from blackboard mostly, and can't solve the problem of dust pollution.There are many outstanding schemes to do more comprehensive research at present, solved this problem to a certain extent, but still can't reach desirable effect at this shortcoming of blackboard brush.

The utility model content

In order to overcome the deficiency of above-mentioned existing blackboard eraser, the purpose of this utility model is to provide a kind of automatic suction dust ash formula blackboard eraser, and it adopts two dust absorption fans are set in blackboard eraser, and the dust that uses dust box splendid attire dust absorption fan to be absorbed.

In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of automatic suction dust ash formula blackboard eraser, it is characterized in that: it is made of dust absorption fan, bristle, rub body, dust box, motor, battery, battery case, switch; Described rub body is a square body, and upper surface is provided with a plurality of blind holes and a plurality of air suction opening, and each blind hole can be held a branch of bristle, and two dust absorption fans are installed in respectively in the rub body, and the rub body two ends are respectively equipped with fin; Described dust box is the square frame body, and both sides are provided with groove, and this groove is corresponding with the fin at rub body two ends, and the side of dust box is provided with gauge tap; Described battery is arranged in the battery case, is installed on the front of dust box, and connects motor by lead.

The beneficial effects of the utility model are: can either blackboard eraser is clean, the dust of wiping can be absorbed again, and also avoided the injury of dust to human body, and simple in structure, easy to operate, be applicable to all schools that use chalk to lecture course.

The specific embodiment

In Fig. 1, Fig. 2, first embodiment shown in Figure 3, a kind of automatic suction dust ash formula blackboard eraser, it is characterized in that: it is made of dust absorption fan (1), bristle (2), rub body (4), dust box (5), motor (6), battery (7), battery case (8), switch (9); Described rub body (4) is a square body, and upper surface is provided with a plurality of blind holes and a plurality of air suction opening (3), and each blind hole can be held a branch of bristle (2), and two dust absorption fans (1) are installed in respectively in the rub body (4), and rub body (4) two ends are respectively equipped with fin; Described dust box (5) is the square frame body, and both sides are provided with groove, and this groove is corresponding with the fin at rub body (4) two ends, and the side of dust box (5) is provided with gauge tap (9); Described battery (7) is arranged in the battery case (8), is installed on the front of dust box (5), and connects motor (6) by lead.

In Fig. 1, second embodiment shown in Figure 3, described motor (6) connects battery case (8) and two dust absorption fans (1) respectively by lead; When two dust absorption fans (1) rotated, the dust that is attached on the bristle (2) will be absorbed by dust absorption fan (1) and be contained in the dust box (5); After the dust in the dust box (5) is filled, dust box (5) can be taken off, the dust in the dust box (5) is disposed, again dust box (5) is installed on the rub body (4), can continue to use.

When using the utility model, open switch (9), grasp dust-absorbing box (5), make the dust on bristle (2) the brushing blackboard, after dust will be attached on the bristle (2), and absorbed fast in the dust box (5) by the dust absorption fan (1) in the rub body (4) rapidly.
