Detailed description of the invention

As shown in Figure 1,2 and 3, the utility model comprises blackboard plate body 6, is arranged on the support side plate 1 with chute 4 of blackboard plate body 6 both sides, two ends are embedded on chute 4 and the dust-absorbing filtering blackboard eraser 2 that can slide up and down along chute 4, be arranged on dust-absorbing filtering blackboard eraser 2 side motor 8, be arranged on blackboard plate body 6 side and the tooth bar 5 be meshed with the gear 9 on motor 8 output shaft, be arranged on blackboard plate body 6 opposite side and the blower fan 3 be communicated with the aspiration chamber on dust-absorbing filtering blackboard eraser 2 by exhausting flexible pipe 11 and be arranged on blackboard plate body 6 lower end bear plate 7; Chute 4 and dust-absorbing filtering blackboard eraser 2 two ends match, motor 8 driven gear 9, and gear 9 engages with tooth bar 5, thus drives whole dust-absorbing filtering blackboard eraser 2 to move up and down along chute 4; The length of dust-absorbing filtering blackboard eraser 2 for just in time can cover blackboard surface, and has and is unlikely to scratch support side plate 1 at the volley, so just can be disposable clean by blackboard-cleaning; Bear plate 7 length consistent with blackboard plate body 6, width is 10-20cm, bears plate 7 and can be used for bearing chalk holder, ruler and some classroom teaching aids, conveniently takes at any time; Exhausting flexible pipe 11 adopts the flexible pipe of extension type, and avoids chute 4 in the process of installing, in order to avoid be involved in chute 4 by exhausting flexible pipe when dust-absorbing filtering blackboard eraser 2 slides on chute 4, causes fault; When mounted, also by clip by or holddown groove the position of exhausting flexible pipe 11 is fixed, when avoiding dust-absorbing filtering blackboard eraser 2 to slide on chute 4, exhausting flexible pipe is involved in chute 4; Exhausting flexible pipe 11 and dust-absorbing filtering blackboard eraser 2 interface are provided with seal washer, ensure that interface can not leak gas when blower fan 3 works; The above motor 8 and blower fan 3 model and size all suitably can adjust according to the size of blackboard, and operating personnel only need just can control motor 8 and blower fan 3 by console switch 20; Motor 8 and blower fan 3 can by a switch control rule also by independent switch control rule; Motor 8 can be auto-manual system motor, its output shaft rotation direction is controlled by manual control switch, thus control whole dust-absorbing filtering blackboard eraser 2 and move up and down, also on motor 8, PLC can be installed, the number of turns of motor 8 output shaft rotation is controlled by PLC, when PLC after motor 8 output shaft rotation to the number of turns set will provide signal, motor 8 output shaft is rotated in the opposite direction, dust-absorbing filtering blackboard eraser 2 so just can be made to move up and down in chute 4; The bristle 12 that described dust-absorbing filtering blackboard eraser 2 comprises aspiration chamber, is arranged on the upper dust-blocking cover 14 of aspiration chamber external upper, is arranged on the lower dust-blocking cover 14-1 of aspiration chamber outer lower side and is arranged on before aspiration chamber outside; Described aspiration chamber comprise for connect bristle 12 and be provided with passage 19 connecting plate 13, be arranged on aspiration chamber inside two-layer above filter cotton 18, be arranged on and between filter cotton 18, be used for the screen pack 16 of isolating filter cotton 18 and the cover plate 15 be connected with aspiration chamber sidewall by rotating shaft 17; Passage 19 is evenly distributed on connecting plate 13, and upper dust-blocking cover 14 and lower dust-blocking cover 14-1 are made up of soft plastic, and upper dust-blocking cover 14 adopts dismountable mode to be connected with aspiration chamber lateral wall with lower dust-blocking cover 14-1 respectively, are convenient to unpick and wash replacing at any time; Bristle 12 lower end 2-5cm is slightly longer than in the lower end of upper dust-blocking cover 14 and lower dust-blocking cover 14-1, when erasing the board, upper dust-blocking cover 14 and lower dust-blocking cover 14-1 can cover bristle 12, and chalk dust can not directly be dropped, and plastic cement dust cover itself is soft, so the chalk dust on blackboard can not be peeled off; Upper dust-blocking cover 14 and lower dust-blocking cover 14-1 had not only prevented chalk dust to disperse everywhere but also the sealing improved, and be convenient to blower fan 3 and can make form larger negative pressure between bristle 12, what chalk dust was filtered is more thorough; Filter cotton 18 is used for filtering bristle 12 and wipes the chalk dust of falling, and separates, just can open top cover 15 after using a period of time between filter cotton 18 with screen pack 16, filter cotton 18 is cleaned, then change clean filter cotton 18, filter cotton 18 can recycle, and reduces use cost; Screen pack 16 prevents filter cotton 18 to be sticked together, and brings inconvenience to replacing; The model of filter cotton 18 and size as required can be suitable adjustment, and the reusable filtering material of the material selection of filter cotton 18; Through cotton 18 absorption of multiple filtration, chalk dust will be filtered, and stay in aspiration chamber, and the exhaust outlet of such blower fan 3 just can be placed directly in indoor; Also be provided with the blower fan supporting plate 10 matched with blower fan 3 in blackboard plate body 6 side, blower fan supporting plate 10 can be used for fixing blower fan 3.

In use, only need open the console switch 20 of motor 8 and blower fan 3, just can work by controlled filter dust-sucking eraser 2, the chalk writing by the time on blackboard is known totally, shutoff operation switch 20, now just can continue to use blackboard.

To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
