Description
技术领域 technical field
本实用新型涉及黑板教学辅助工具，具体涉及一种黑板擦清理装置。 The utility model relates to a blackboard teaching auxiliary tool, in particular to a blackboard eraser cleaning device.
背景技术 Background technique
目前，大多数学校在课堂教学中仍然是用黑板擦将书写在黑板上的粉笔字擦掉。黑板擦使用的材料主要是毛毡，而毛毡内可容纳粉笔粉尘的空间有限，由于不能随时彻底清楚粉笔粉尘，久之黑板擦毛毡内粉笔粉尘饱和，如继续使用不仅造成大量粉笔粉尘飞扬，危害师生健康，同时黑板也不易擦干净，影响课堂教学。若使用拍打的方式清除，则又造成教室环境的二次污染。 At present, most schools still use a blackboard eraser to erase the chalk words written on the blackboard in classroom teaching. The material used for blackboard erasers is mainly felt, and the space that can accommodate chalk dust in the felt is limited. Since the chalk dust cannot be completely cleared at any time, the chalk dust in the blackboard eraser felt is saturated for a long time. If you continue to use it, it will not only cause a large amount of chalk dust to fly, but also endanger teachers and students. It is healthy, and the blackboard is not easy to wipe clean at the same time, which affects classroom teaching. If it is removed by beating, it will cause secondary pollution of the classroom environment.
因此，市面上也出现一些对黑板擦除尘产品。但这些产品大多结构复杂、使用不便，并且对黑板擦本身造成较大损伤，减短黑板擦的使用寿命，同时这些除尘产品本身也不方便清理，增大了使用者的工作量。 Therefore, some products for removing dust from blackboard erasers also appear on the market. However, most of these products are complex in structure, inconvenient to use, and cause great damage to the blackboard eraser itself, shortening the service life of the blackboard eraser, and these dust removal products themselves are also inconvenient to clean, increasing the workload of the user.
发明内容 Contents of the invention
