Abstract
An electric chalk dust collecting device comprises a collecting box and a miniature electric dust collector. The collecting box comprises a dust collection box and a dust storage box. The miniature electric dust collector comprises a shell, a direct-current electric exhaust fan, a battery box, a dust collection port and fan blades. The miniature electric dust collector is arranged on the upper side in the dust collection box, and an opening in the upper portion of the dust collection box is the dust suction port. Due to the improvement, the electric chalk dust collecting device has the advantages of being thorough in dust collection, convenient to detach, safe and environmentally friendly.
Description
Technical field
The present invention relates to a kind of teaching aid, relate in particular to a kind of for collecting the electronic chalk dust collecting device of chalk dust.
Background technology
In modern teaching, teacher generally uses chalk teaching, but chalk easily produces a large amount of chalk dusts in teaching, chalk dust spreads in air, and chalk dust will be sucked in lung by Faculty and Students, directly affects teachers and students' health, in existing technology, mostly use disposable box to reclaim, but can only reclaim like this chalk dust under wafing, the chalk dust flying away cannot reclaim, and also can pollute.
Summary of the invention
The present invention is directed to existing issue, provide a kind of pick-up performance good.Reclaim the electronic chalk dust collecting device that chalk dust is convenient, reduce pollution.
The scheme of technical solution problem of the present invention is: a kind of electronic chalk dust collecting device, comprise disposable box and miniature electric dust suction device, described disposable box comprises dust-absorbing box and dust-collecting box, described miniature electric dust suction device comprises direct current drive air exhauster, battery case, fan blade, described miniature electric dust suction device is arranged at dust-absorbing box upper inside, described dust-absorbing box upper opening place is suction port, under the drive of direct current drive air exhauster, fan blade starts to rotate, and discharges wind-force by chalk dust inspiration dust-absorbing box by suction port.
Further improvement of the present invention is: on described battery case, be equipped with and select shift knob, and the both positive and negative polarity of battery case and shift knob are connected.
Further improvement of the present invention is: described dust-absorbing box is inverted trapezoidal structure, and dust-collecting box is rectangle and is positioned at dust-absorbing box below, described dust-absorbing box and dust-collecting box internal communication.
Further improvement of the present invention is: in described dust-collecting box, be covered with active carbon layer.
Further improvement of the present invention is: described dust-absorbing box and dust-collecting box joint portion are externally embedded type structure.
Further improvement of the present invention is: in described dust-absorbing box, be provided with one deck screen pack.
The invention has the beneficial effects as follows: 1. dust suction is thorough.2. convenient disassembly.3. reducing chalk dust flies away.4. safety and environmental protection.

Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
1. the present embodiment is as illustrated in figs. 1 and 2: a kind of electronic chalk dust collecting device, comprise disposable box and miniature electric dust suction device, described disposable box comprises dust-absorbing box 1 and dust-collecting box 2, described miniature electric dust suction device comprises direct current drive air exhauster 3, battery case 4, fan blade 9, described miniature electric dust suction device is arranged at dust-absorbing box 1 upper inside, described dust-absorbing box 1 upper opening place is suction port 8, under the drive of direct current drive air exhauster 3, fan blade 9 starts to rotate, discharge wind-force by chalk dust inspiration dust-absorbing box 1 by suction port 8, on described battery case 4, be equipped with and select shift knob 5, and both positive and negative polarity and the shift knob of battery case 4 are connected, described dust-absorbing box 1 is inverted trapezoidal structure, dust-collecting box 2 is for rectangle and be positioned at dust-absorbing box 1 below, described dust-absorbing box 1 and dust-collecting box 2 internal communication, in described dust-collecting box 2, be covered with active carbon layer 6, described dust-absorbing box 1 and dust-collecting box 2 joint portions are externally embedded type structure, in described dust-absorbing box 1, be provided with one deck screen pack 7.
The present invention is in the time that reality is used, conventionally chalk dust is that this is that electronic chalk dust collecting device is installed on to blackboard bottom, opens miniature electric dust suction device because the effect of gravity descends slowly and lightly downwards on chalk frame, under the drive of direct current drive air exhauster 3, fan blade 9 starts to rotate, and discharges wind-force by chalk dust inspiration dust-absorbing box 1 by suction port 8, because dust-absorbing box 1 box body adopts inverted trapezoidal structure, inner wall smooth, the downward landing of chalk dust, falls into dust-collecting box 2, for having prevented that foreign material from falling into; Described dust-collecting box 2 surroundings are covered with layer of active carbon layer 6, so just can, by adsorbing powder dust in dust-collecting box 2, prevent that it from flying away; In dust-absorbing box 1, be also provided with one deck screen pack 7, enter dust-collecting box 2 for tackling foreign material, easy cleaning, dust-absorbing box 1 and dust-collecting box 2 joint portions are externally embedded type structure, so just can dismantle, and are convenient to the cleaning of dust-absorbing box 1 and dust-collecting box 2.
