Detailed description of the invention
As shown in Fig. 1 ~ 3, a kind of dust-free blackboard, it comprises: blackboard 1, run through the blackboard eraser 2 being arranged at blackboard 1 front, the slide rail 4 being fixedly installed on the blackboard left and right sides, be arranged at the ash groove 5 on the downside of blackboard and be connected with ash groove 5 take out dirt device 6; Described blackboard eraser 2 two ends are slidably arranged on slide rail 4 respectively by support bar 3.
Described dirt device 6 of taking out comprises the escape pipe 63 that air inlet pipe 61 that circulating fan 62 is connected with circulating fan 62 air inlet is connected with circulating fan 62 gas outlet and the removable filter net 64 be arranged between described air inlet and gas outlet; Described air inlet pipe 61 is arranged at ash groove 5 one side bottom, and described escape pipe 63 is arranged on the sidewall of described ash groove 5 opposite side; Described escape pipe 63 is inclined relative to horizontal to canyon.Bleed in ash groove one end, the other end is blown, and prevent dead angle, dust discharge is respond well.
Described ash groove 5 sidewall upper is provided with caulking gum 12, and described blackboard eraser 2 left and right sides is provided with the sealing plate corresponding with described caulking gum 12.When taking out dirt, blackboard eraser 2 is dropped to bottom, now blackboard eraser 2 and ash groove 5 form closed cavity by caulking gum and sealing plate, chalk dust in cavity can not permeate in air, open and take out dirt device dust is discharged ash groove, confined space effectively prevents dust recycling to be detrimental to health.
The dust board 10 that described blackboard eraser 2 comprises scrubbing brush 8, is arranged at the rubber baffle 11 on the upside of scrubbing brush 8 and is fixedly installed on the downside of scrubbing brush 8.Be provided with type dust arrester in the upper and lower both sides of scrubbing brush, leave gap between described dust board 10 and blackboard 1, dust can fall into ash groove 5 by gap, prevents dust recycling.
Described dust board 10 is also provided with handle 7.
When needs blackboard wiping, holding handle about 7 push-and-pull blackboard eraser 2 can carry out wiping.Wiping is complete, is dropped on ash groove 5 by blackboard eraser 2, makes it closely be connected, and opens to take out dirt device switch and carry out taking out dirt.Because ash groove upper end is provided with caulking gum 12, blackboard eraser 2 there is sealing plate effectively can ensure ash groove 5 sealing, prevented dust from permeating in air.Re-use after screen pack 64 can being pulled down cleaning after using a period of time, can be recycled.
Good effect of the present utility model is to adopt integral type blackboard eraser, traverses whole blackboard, and erasing area is large, only by upper and lower for blackboard eraser push-and-pull, need accelerate efficiency when needs large area blackboard wiping; Blackboard eraser is provided with rubber baffle and dust board effectively prevents the dust when blackboard wiping from filling the air; Blackboard bottom is provided with gathers dust groove and takes out dirt device, effectively stops dust to permeate in air, reduces body effect, and the filter screen taken out in dirt device is detachable, and cleaning Posterior circle uses, environmentally-friendly sanitary.
