Description

Automatic blackboard eraser

The utility model relates to a kind of blackboard eraser, particularly a kind of automatic blackboard eraser.

Culture and education is basic education particularly, mainly finishes on the classroom, and blackboard is the requisite educational aid of classroom instruction.At present, the employed educational aid of school is still based on traditional blackboard.And the traditional blackboard dust from flying of when wiping examination, both having wasted time and energy, the numerous teachers and students' of grievous injury is healthy, and every class only 45 minutes just needs a few minutes and erase the board, and has wasted limited instructional blocks of time.

But the purpose of this utility model provides a kind of blackboard eraser of automatic blackboard cleaning, only need press operating key during use, blackboard eraser can be on blackboard left and right wiping, and wipe arbitrarily or keep writing on the blackboard arbitrarily, the while dust is sucked the dust box automatically and is carried out the water dust removal process, can eliminate flying upward of dust fully; Pressing stop key after wiping is intact gets final product.

The purpose of this utility model is to realize by such technical scheme, and it includes blackboard, guide frame, wipes motor, brush axle, brush piece, gear, traction electric machine, pulley, steel wire rope, fan, dust box, blackboard eraser, operating key, roller etc.It is characterized in that: on the upper and lower limit of blackboard one guide frame is housed respectively, pulley, roller and steel wire rope are housed respectively in the guide frame; Guide frame the right has an axostylus axostyle to connect pulley up and down, and is connected with the axle of traction electric machine, and it is left and right mobile to draw blackboard eraser; Wipe motor and be connected with gear, this gear reaches the gear that links to each other with brush axle with idler gear again and is meshing with each other; Wiping drive brush axle running under the active force of motor, blackboard eraser is wiped blackboard automatically, and the gear that the gear of brush axle lower end links to each other with fan is meshed, and drives the fan rotation, and with the dust suction dust box under wiping, only need clean a dust box and get final product every day.

The utility model is to use like this: during use, press operating key, blackboard eraser is wiped arbitrarily under the acting in conjunction of wiping motor and traction electric machine or is kept.Being a teacher needs to keep the content of left side, only wipe the content of right-hand part, then only need to start traction electric machine, when blackboard eraser moves to need wiping examination part, restart and wipe motor, the brush axle rotation, the brush piece is thrown out of with blackboard and contacts, blackboard eraser begins wiping, and when blackboard eraser moved on to the right-hand member limit switch, blackboard eraser stopped automatically.Because traction electric machine can positive and negatively rotate, so also can begin to wipe to left end from right-hand member.

Owing to adopted such scheme, the utlity model has following advantage:

1, with self-propelled track design, simple and direct, convenient, time saving and energy saving;

2, adopt automatic wind exhaust control of dust, dust collect unit by water, avoided dust from flying, improved teacher's worker

Make environment, can improve the efficient of giving lessons;

3, adopt Double Motor Control, can wipe arbitrarily, keep arbitrarily;
