Abstract

The utility model relates to a dust-absorbing blackboard eraser, comprising brushing, a brush body, a battery case, a dust case, a motor, storage batteries, and a dust collector. The brush body is square in shape; the upper surface of the brush body is provided with a plurality of blind holes and a plurality of dust-absorbing holes; each blind hole receives a bunch of the brushing; the dust collector is disposed at joint between the brush body and the dust case; two ends of the brush body are provided with convex edges; the dust case is square in shape; a side of the dust case is provided with a control switch; the storage batteries are disposed in the battery case and disposed on the right side of the dust case, and are connected with the motor through leads; and a charging hole is disposed in the battery case. The dust-absorbing blackboard eraser can clean up a blackboard, absorb dust wiped down, and prevent the dust from harming human bodies, and is simple in structure, easy to operate and suitable for all schools employing chalks for teaching.

Description

Dust absorption blackboard eraser

Technical field

The utility model relates to a kind of blackboard eraser, especially a kind of dust absorption 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

At the problem of above-mentioned existing blackboard eraser, the purpose of this utility model is to provide a kind of dust absorption blackboard eraser, and it adopts and at rub body and dust box connection motor and dust exhaust apparatus is set, and powers to motor by battery.

In order to realize that the technical scheme that the purpose of this utility model adopts is: a kind of dust absorption blackboard eraser is characterized in that: it is made of bristle, brush body, battery case, dust box, motor, battery, dust catcher; Described brush 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 dust catcher is installed in brush body and dust box connection, and the brush body two ends are respectively equipped with fin; Described dust box is square, and both sides are provided with groove, and this groove is corresponding with the fin at brush 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, and the charging hole is arranged on the battery case.

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 dust absorption blackboard eraser is characterized in that: it is made of bristle (2), brush body (4), battery case (5), dust box (6), motor (7), battery (9), dust catcher (10); Described brush body (4) is a square body, and upper surface is provided with a plurality of blind holes and a plurality of air suction opening (8), and each blind hole can be held a branch of bristle (2), and dust catcher (10) is installed in brush body (4) and dust box (6) connection, and brush body (4) two ends are respectively equipped with fin; Described dust box (6) is square, and both sides are provided with groove, and this groove is corresponding with the fin at brush body (4) two ends, and the side of dust box (6) is provided with gauge tap (3); Described battery (9) is arranged in the battery case (5), is installed on the front of dust box (6), and connects motor (7) by lead, and charging hole (1) is arranged on the battery case (5).

In Fig. 2, second embodiment shown in Figure 3, described motor (7) connects switch (3) and dust catcher (10) by lead; When dust catcher (10) is worked, the dust that is attached on the bristle (2) can be absorbed to dust box (6) from dust hole (8).

In Fig. 1, the 3rd embodiment shown in Figure 2, described brush body (4) is connected by the groove of fin with dust box (6); When the dust in the dust box (6) arrives when a certain amount of, dust box (6) is taken off, and, again brush body (4) is connected with dust box (6) after the cleaning of the ash of the dust in the dust box (6), get final product.

When using the utility model to erase the board, open switch (3), grasp dust box (6) and make bristle (2) the dust ash on the blackboard be wiped and, get final product the absorption of dust ash; After the electric weight in the battery (9) uses, the battery (9) in the battery case (5) can be changed, also can insert charging hole (1) accumulators (9) and charge by special charger.
