Abstract
The invention belongs to the field of education supplies and particularly relates to a dust collection blackboard. The dust collection blackboard comprises a blackboard body and is characterized in that an upper cross beam and a lower cross beam of the blackboard body are each internally provided with a sealed hollow sliding groove; a hollow sliding block is embedded in each sliding groove; the sliding blocks are connected with a rectangular blackboard eraser which is internally hollow; a cavity of the blackboard eraser is internally provided with six to eight small-size motors, and fan blades are connected to each small-size motor; an induced draft fan is connected to the sliding groove located in the lower portion of the blackboard body through a pipeline; and one side of the induced draft fan is connected with a collection box. According to the dust collection blackboard, the blackboard can be automatically cleaned, and dust produced during blackboard cleaning can be absorbed at the same time; the absorbed dust is collected in the dust collection box convenient to take out, not only is manpower saved, but also cleanliness and sanitation are achieved, and convenience is brought to teaching activities of people, so that burdens are relieved.
Description
(1) technical field
The invention belongs to realia field, particularly to a kind of dust-absorbing blackboard.
(2) background technology
Blackboard is a kind of instrument indispensable in people's education activities.Every class will erase the board after class, but dust from flying when erasing the board, chalk dust enters respiratory tract with air, and teacher and the healthy of classmates are caused very major injury.Used time, the dust being scattered is not easy to cleaning, is required for removing these dusts every day, cumbersome.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that a kind of dust-absorbing blackboard being suitable to education activities.
The present invention is achieved through the following technical solutions:
A kind of dust-absorbing blackboard, including blackboard body, is characterized in that: be provided with the hollow runner of closing inside described blackboard body lower and upper cross-member；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, is provided with 6-8 micro-machine in cavity, this micro-machine is connected to flabellum；Described blackboard body bottom chute is connected to air exhauster by pipeline, and this air exhauster side is connected with disposable box.
Bottom, described blackboard body side is provided with on and off switch.
Being provided with telescopic baffle in described chute, this telescopic baffle is connected with chute and slide block respectively.
Described blackboard eraser upper surface is provided with handle.
When the present invention uses, turning on the power switch, the fan in blackboard eraser rotates, promoting blackboard eraser, chalk powder is sucked in blackboard eraser cavity by fan, owing to air exhauster makes formation 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 so that chalk powder will not leak outside.
The invention has the beneficial effects as follows: this dust-absorbing blackboard can absorb the dust produced that erases the board while automatic blackboard cleaning, the dust collection absorbed, in the convenient dust collecting box taken out, had both saved manpower, again clean hygiene, education activities for people bring facility, alleviate burden.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is the structural representation of the present invention.
Fig. 1 is the chute top view of the present invention.
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, on and off switch, 10, telescopic baffle, 11, handle.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment includes blackboard body 1, is provided with the hollow runner 2 of closing inside described blackboard body 1 lower and upper cross-member；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 to flabellum 6；Described blackboard body 1 bottom chute 2 is connected to 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 on and off switch 9.Being provided with telescopic baffle 10 in described chute 2, this telescopic baffle 10 is connected with chute 2 and slide block 4 respectively.Described blackboard eraser 3 upper surface is provided with handle 11.
When the present invention uses, turning on the power switch 9, the fan in blackboard eraser 3 rotates, promoting blackboard eraser 3, chalk powder is sucked in blackboard eraser 3 cavity by fan, owing to air exhauster 7 makes formation 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 so that chalk powder will not leak outside.
Describing the present invention by way of example above, but the invention is not restricted to above-mentioned specific embodiment, all any changes done based on the present invention or modification belong to the scope of protection of present invention.
