As further program of the utility model:The lateral location of one inner chamber is provided with the charging to lithium battery Mouthful.
As the utility model further scheme:The fan is arranged to multiple, and multiple fans are by the first electricity Machine drives.
As the utility model further scheme:The switch switchs for piezo-resistance.
As the utility model further scheme:The side of the dust storage chamber is detachable.
Compared with prior art, the beneficial effects of the utility model are:At the side of hand-held blackboard eraser, piezo-resistance Automatic processing circuit is switched, now cotton brush is wiped the chalk marking, fan is by the first motor by the second motor-driven rotation Driving is rotated, and negative pressure is formed in the 3rd inner chamber, and external mix has the air of dust from air inlet after the filtering of filter screen, dust It is trapped within dust storage chamber, air is blown out from air outlet, and will effectively can erase the board caused dust suction, reduce dust and dissipate Hair influence to caused by Faculty and Students' health, it is easy to use, it can be widely used in school, enterprise.
Brief description of the drawings
Fig. 1 is a kind of structural representation of dust-free black board eraser.
Fig. 2 is a kind of rearview of dust-free black board eraser.
In figure:1- blackboard erasers, 2-USB interfaces, 3- lithium batteries, 4- switches, 5- air inlets, 6- dividing plates, 7- filter screens, 8- go out Air port, 9- cottons brush, 10- fans, 11- dust storage chambers.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, a kind of dust-free black board eraser, including blackboard eraser 1, the blackboard Rub body 1 is that the superstructure for the structure wherein blackboard eraser 1 that upper and lower both sides are respectively provided with inner chamber is separated into by dividing plate 6 and filter screen 7 First inner chamber, second inner chamber and the 3rd inner chamber, lithium battery 3 is installed, blackboard eraser 1 is in corresponding first in the first inner chamber Switch 4 is provided with the lateral location of chamber, second inner chamber is dust storage chamber 11, and air inlet 5 is offered on the two sides of dust storage chamber 11, As the passage that enters of dust, intracavitary is provided with fan 10 in the 3rd, and fan 10 is driven by the first motor, the side of the 3rd inner chamber Air outlet 8 is offered, the position of air outlet 8 is corresponding with fan 10, forms negative pressure in the 3rd inner chamber during startup, and external mix has From air inlet 5 after the filtering of filter screen 7, dust is trapped within dust storage chamber 11 air of dust, and air blows from air outlet 8 Go out, will effectively can erase the board caused dust suction, reduce diffussion of dust shadow to caused by Faculty and Students' health Ring;The underlying structure surface of the blackboard eraser 1 is provided with multiple cotton brushes 9, and multiple cotton brushes 9 are driven by the second motor, by Existing conventional technology when one motor drives multiple mechanisms by belt or gear while rotated, therefore herein not to specific Driving and attachment structure are described, but the not integrality of influence technique scheme;Second motor, the first motor are electrically connected with Lithium battery 3 and switch 4, when hand-held blackboard eraser 1, closure switch 4 connect circuit, and fan 10 and cotton brush 9 rotate, can be right respectively Dust is sucked and the chalk marking is wiped.
