(3) utility model content
The utility model, in order to make up the deficiencies in the prior art, provides a kind of dust-absorbing blackboard being suitable for education activities.
The utility model is achieved by the following technical solution:
A kind of dust-absorbing blackboard, comprises blackboard body, it is characterized in that: described blackboard body lower and upper cross-member inside is provided with closed hollow runner; Described chute is embedded with the slide block of hollow, and this slide block is connected with rectangle blackboard eraser; Described blackboard eraser inner hollow, be provided with 6-8 micro-machine in cavity, this micro-machine is connected with flabellum; Described blackboard body bottom chute is connected with air exhauster by pipeline, and this air exhauster side is connected with disposable box.
Bottom, described blackboard body side is provided with power switch.
Be provided with telescopic baffle in described chute, this telescopic baffle is connected with slide block with chute respectively.
Described blackboard eraser upper surface is provided with handle.
When the utility model uses, turn on the power switch, the fan turns in blackboard eraser, promote blackboard eraser, chalk powder sucks in blackboard eraser cavity by fan, because air exhauster makes to form negative pressure in blackboard eraser cavity, chalk powder has arrived in chute along the cavity of slide block, is finally drawn onto in disposable box; In blackboard eraser moving process, telescopic baffle remains that chute is closed, and chalk powder can not be leaked outside.
The beneficial effects of the utility model are: this dust-absorbing blackboard can the simultaneously stability of automatic blackboard cleaning erase the board produce dust, the dust collection absorbed, in the convenient dust collecting box taken out, both saved manpower, again clean hygiene, for the education activities of people bring facility, alleviate burden.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
In figure, 1, blackboard body, 2, chute, 3, blackboard eraser, 4, slide block, 5, micro-machine, 6, flabellum, 7, air exhauster, 8, disposable box, 9, power switch, 10, telescopic baffle, 11, handle.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises blackboard body 1, and described blackboard body 1 lower and upper cross-member inside is provided with closed hollow runner 2; Described chute 2 is embedded with the slide block 4 of hollow, and this slide block 4 is connected with rectangle blackboard eraser 3; Described blackboard eraser 3 inner hollow, is provided with 6-8 micro-machine 5 in cavity, this micro-machine 5 is connected with flabellum 6; Described blackboard body 1 bottom chute 2 is connected with air exhauster 7 by pipeline, and this air exhauster 7 side is connected with disposable box 8.Bottom, described blackboard body 1 side is provided with power switch 9.Be provided with telescopic baffle 10 in described chute 2, this telescopic baffle 10 is connected with slide block 4 with chute 2 respectively.Described blackboard eraser 3 upper surface is provided with handle 11.
When the utility model uses, turn on the power switch 9, fan turns in blackboard eraser 3, promote blackboard eraser 3, chalk powder sucks in blackboard eraser 3 cavity by fan, because air exhauster 7 makes to form negative pressure in blackboard eraser 3 cavity, chalk powder has arrived in chute 2 along the cavity of slide block 4, is finally drawn onto in disposable box 8; In blackboard eraser 3 moving process, telescopic baffle 10 remains that chute 2 is closed, and chalk powder can not be leaked outside.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
