Description
Technical field
The present invention relates to a kind of blackboard eraser, particularly a kind of dust absorption blackboard eraser.
Background technology
One of instrument that chalk mainly uses when being and giving lessons, upper class hour, teacher uses blackboard eraser wiping chalk writings, in wiping process, a large amount of chalk dusts is brushed down, chalk dust drops on Faculty and Students and is inhaled in body with it or with air, thus threatens the health of personnel in classroom, brings a lot of puzzlements to the personnel of attending class and the personnel of listening to the teacher.A variety of dust-removing blackboard is had to wipe on the market at present, or the excessive inconvenient operation of volume, or dust removing effects is bad, still can't resolve the situation that powder disorderly flies.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of dust absorption blackboard eraser, with relatively simple structure, occupation mode easily, small occupation of land space, make user can carry out dust suction and clean operation whenever and wherever possible, the technical solution of the utility model is as follows: a kind of dust absorption blackboard eraser, comprise rub body 1, rub body 1 inner hollow forms installation cavity 2, installation cavity 2 one end open, opening part is provided with wiping board 3, wiping board 3 is provided with rubbing head 4 and the air suction opening 5 of uniform intervals layout, adsorbing powder dust body 6 is provided with in the installation cavity 2 of wiping board 3, installation cavity 2 inside in adsorbing powder dust body 6 is provided with dust absorption fan 7 and drives battery 8, wherein dust absorption fan 7 is connected with drive motors 9 by driving shaft 10, drive motors 9 is affixed with installation cavity inner surface, battery 8 is driven to be connected with the switch 12 and drive motors 9 being arranged on rub body 1 outer surface by power line.
The technical program can be optimized for, and described adsorbing powder dust body 6 is the cavernous body of porous.
The technical program can also be optimized for, and described switch 12 is two-way switch.
Be optimized for further, described rubbing head 4 bottom is cylindrical shape supporter, and top is hemispherical sponge brush.
More can be optimized for, described driving battery 8 is arranged in battery case 11, and battery case 11 is affixed with installation cavity 2 inner surface.
As a kind of prioritization scheme of the technical program, can be provided with dust suction gap between described adsorbing powder dust body 6 and wiping board 3, the scope in dust suction gap be 3-10mm.
The beneficial effects of the utility model are:
With low cost; Structure is simple, compact; Use easy to operate, effective, quick; Take up room little; Convenient management; Be swift in response.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is that the utility model is not containing the internal structure schematic diagram of wiping board;
Fig. 3 is the internal structure schematic diagram that the utility model does not contain wiping board and adsorbing powder dust body;
Wherein: 1, rub body; 2, installation cavity; 3, wiping board; 4, rubbing head; 5, air suction opening; 6, adsorbing powder dust body; 7, dust absorption fan; 8, battery is driven; 9, drive motors; 10, driving shaft; 11, battery case; 12, switch.
Detailed description of the invention
Specific embodiment 1: the technical program is described in detail referring to shown in Fig. 1, Fig. 2 and Fig. 3.
A kind of dust absorption blackboard eraser, comprise rub body 1, rub body 1 inner hollow forms installation cavity 2, installation cavity 2 one end open, opening part is provided with wiping board 3, wiping board 3 is provided with rubbing head 4 and the air suction opening 5 of uniform intervals layout, adsorbing powder dust body 6 is provided with in the installation cavity 2 of wiping board 3, installation cavity 2 inside in adsorbing powder dust body 6 is provided with dust absorption fan 7 and drives battery 8, wherein dust absorption fan 7 is connected with drive motors 9 by driving shaft 10, drive motors 9 is affixed with installation cavity inner surface, battery 8 is driven to be connected with the switch 12 and drive motors 9 being arranged on rub body 1 outer surface by power line.Adsorbing powder dust body 6 is the cavernous body of porous.Described switch 12 is two-way switch.Described rubbing head 4 bottom is cylindrical shape supporter, and top is hemispherical sponge brush.Described driving battery 8 is arranged in battery case 11, and battery case 11 is affixed with installation cavity 2 inner surface.The dust suction gap arranged between described adsorbing powder dust body 6 and wiping board 3 is 3mm.
Operating process: when user needs the chalk trace on blackboard wiping, the switch 12 of ash-collecting blackboard eraser is got to forward condition, drive motors 9 is started working, dust absorption fan 7 rotates, produce suction, chalk dust rubbing head 4 wiped is sucked by air suction opening 5, be adsorbed onto on the adsorbing powder dust body 6 of porous, owing to being provided with dust suction gap between adsorbing powder dust body 6 and wiping board 3, make suction larger, and dust can be made fully to disperse in this space, be adsorbed on adsorbing powder dust body 6 more equably, effectively can increase the adsorbance of adsorbing powder dust body 6.
After adsorbing powder dust body 6 has adsorbed the dust of q.s, need to clean.By the surface of one piece of clean sheet to wiping board 3, reverse state got to by switch 12, and drive motors 9 drives dust absorption fan 7 to reverse, and produces blowing force, and blown out by air suction opening 5 by the dust of absorption in adsorbing powder dust body 6, powder falls into cleaning cloth.If dust remains more, also wiping board 3 can be taken off from installation cavity 2, take out adsorbing powder dust body 6, the dust on installation cavity 2 and adsorbing powder dust body 6 is thoroughly removed.
Specific embodiment 2: the dust suction gap arranged between adsorbing powder dust body 6 and wiping board 3 is outside 10mm, and other is with specific embodiment 1.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill belonging to the utility model, under the prerequisite not departing from this utility model thinking, simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
