| titleOfInvention | A kind of dustless English teaching system |
| abstract | The invention discloses a kind of dustless English teaching system, including several magnet strips being arranged in blackboard and the slide rail for being arranged on blackboard left and right ends, slide plate with roller is set in the slide rail, scraper plate is provided with the upside of the slide plate, bottom plate is provided with the downside of the slide plate, one end that the bottom plate is contacted with blackboard is provided with fur, the slide plate two ends are provided with baffle plate, the baffle plate, bottom plate, scraper plate forms iron particle accommodating chamber after being contacted with blackboard, the iron particle of white coating is scribbled in iron particle accommodating chamber provided with several peripheries, the blackboard top, which is provided with, to be used to drive the drive mechanism that slide plate is moved up and down, blackboard-cleaning mechanism on the slide plate, the blackboard-cleaning mechanism connection vibration dust-collection mechanism, the vibration dust-collection mechanism is provided with dust non-proliferation mechanism.Teacher can carry out setting-out at a distance, draw four line lattice specifications, while setting-out can blackboard wiping, and dust can absorb, and dust descends slowly and lightly seldom, and plant running stably will not damage blackboard. |
