Abstract

The invention provides a closed eraser box. The eraser box comprises an eraser board and an eraser box body. An eraser sponge is attached to the surface of the eraser board. The inner wall of the eraser box body is joggled with a support plate. The surface of the support plate is welded to a support rod. The surface of the support rod is fixedly connected to a motor. The output shaft of the motoris fixedly connected to a rotation shaft through a shaft coupling. The surface of the rotation shaft is welded with a flabellum. A vibration tube sleeves the surface of the rotation shaft. The surfaceof the support plate is welded with a limiting rod. The surface of the limiting rod is in an L shape. The surface of the vibration tube is provided with a limiting groove. One end of the limiting rodis slidably connected to the inner wall of the limiting groove. The eraser box relates to the stationery field. The structure of the closed eraser box is simple, a netted elastic force mechanism is used to resonate the eraser, dust on an eraser surface can be high-efficiently and comprehensively removed, and the influence of the dust on teachers and students is reduced so that a problem that whenthe chalk dust of an existing blackboard eraser falls off, the dust is not easy to fall, and the floating dust seriously affects the health of the teachers and students is effectively solved.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a closed eraser box. Background technique [0002] The blackboard eraser is suitable for stationery to wipe the blackboard. In the process of teaching blackboard writing, the blackboard eraser must be used to wipe the blackboard. During this process, thick chalk dust will be absorbed on the surface of the blackboard eraser. The chalk dust on the blackboard eraser needs to be cleaned frequently, otherwise It will be inconvenient to wipe the blackboard clean. At present, chalk dust is mainly removed by beating. Although the dust on the eraser can be removed, the dust cannot be quickly and efficiently removed due to the tight contact between the beating surface of the eraser and the beating surface, and the beating process A large amount of dust that produces also exists the problem that affects teachers and students' health, and when current blackboard eraser comes off chalk dus...
