Abstract
The utility model provides a multi-purpose electrostatic dedusting eraser, which belongs to the technical field of stationery, and structurally comprises an upper eraser and a lower eraser. An upper half portion and a lower half portion of a groove are respectively arranged on the surface of the upper eraser and the surface of the lower eraser; mixed eraser bristles and a powder inlet are installed inside the groove; the mixed eraser bristles are higher than a frame of the groove; a dust collecting box is respectively arranged in the hollow insides of the upper eraser and the lower eraser; and a clamping groove and a convex strip matching in a fastening manner are respectively arranged on the contact edges of the upper eraser and the lower eraser. Compared with the prior art, the multi-purpose electrostatic dedusting eraser has the advantages of reasonable design, simple structure, convenient use and the like, can be used for cleaning school blackboards, can also be used as a clothes dust removing eraser and a carpet dust removing eraser, and has wide application range.
Description
Technical field
The utility model relates to the school supply and stationery technical field, but a kind of specifically dedusting, the electrostatic precipitation blackboard erasers of using that erase the board more.
Background technology
At present, the blackboard eraser that school uses generally all is traditional blackboard eraser of normal style, each all can make that chalk dust disperses in the classroom when clearing up blackboard after class everywhere, classmate and teacher earlier in the classroom are the victim forever, had a strong impact on academics and students's physical and mental health, polluted classroom environment simultaneously, and existing blackboard eraser many times can't be with the blackboard wiped clean, need rag could further clean chalk dust residual on the blackboard, occurred a kind of electric dust absorption blackboard eraser in the prior art, though the phenomenon of having avoided powder to fly upward, but because cost is higher, be not easy to popularize and use, and damaged, service life is shorter.Both cost was low but blackboard eraser is not arranged at present as yet, can accomplish the dust-free cleaning blackboard again.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provide a kind of dust suction convenient, use the simple electrostatic precipitation blackboard erasers of using more.
The technical solution of the utility model realizes in the following manner, should use the electrostatic precipitation blackboard eraser more, its structure comprises blackboard eraser, following blackboard eraser, last blackboard eraser, following blackboard eraser surface have the first half and the latter half of groove, be equipped with in the groove and mix snag and be provided with powder inlet, mix snag and be higher than the groove frame, last blackboard eraser is with following blackboard eraser inner hollow and be provided with dust-collecting box, is respectively arranged with draw-in groove and the raised line that clamping cooperates at last blackboard eraser with the engagement edge of following blackboard eraser.
Described upper plate rubdown face is provided with lever.
The groove frame is socketed with sponge brush.
Be doped with silk in the described mixing snag.
The beneficial effect that the utility model is compared with prior art produced is:
Of the present utility model many with the electrostatic precipitation blackboard eraser have simple in structure, easy to use, characteristics such as be skillfully constructed, utilize electrostatic principle to make, can produce static and be used for the dust suction dedusting after snag and the object friction, anti-wear performance is good, the chalk bits of being drawn can poured out behind the blackboard eraser up and down under the dismounting, use simple, practical, environmentally-friendly sanitary, have wide range of applications, not only can be used for school's blackboard cleaning, can also wipe as clothing dedusting wiping, carpet dedusting and use, can become the good assistant of family's indispensability.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is left views of the present utility model;
Accompanying drawing 3 is the cutaway views that are connected of going up blackboard eraser and following blackboard eraser.
Mark in the accompanying drawing is represented respectively:
1, following blackboard eraser, 2, go up blackboard eraser, 3, sponge brush, 4, powder inlet, 5, groove, 6, mix snag, 7, lever, 8, dust-collecting box, 9, raised line, 10, draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing the electrostatic precipitation blackboard erasers of using of the present utility model are done following detailed description the in detail more.
As accompanying drawing 1, Fig. 2, shown in Figure 3, should use the electrostatic precipitation blackboard eraser more, its structure is by last blackboard eraser 2, following blackboard eraser 1 splicing is formed, last blackboard eraser 2, following blackboard eraser 1 surface has the first half and the latter half of groove 5, be provided with lever 7 at the back side of last blackboard eraser 2, be equipped with in the groove 5 and mix snag 6 and be provided with powder inlet 4, mix in the snag 6 and be doped with silk, so just can the Convenient blackboard friction wipe generation static, mix snag 6 and be higher than groove 5 frames, be socketed with sponge brush 3 on groove 5 frames, when running into the unclear writing of wiping, can make cleaning for the second time, last blackboard eraser 2 is with following blackboard eraser 1 inner hollow and be provided with dust-collecting box 8, is respectively arranged with draw-in groove 10 and the raised line 9 that clamping cooperates at the last blackboard eraser 2 and the engagement edge of following blackboard eraser 1.
After wiping finishes, will go up blackboard eraser 2 and take apart with following blackboard eraser 1, pour out the dust in the dust-collecting box 8 after, clamping gets up to continue use once more, wiping effect is good.
