Abstract

The invention provides a multi-functional blackboard wiping device. The multi-functional blackboard wiping device comprises an installation frame fixedly installed on the periphery of a blackboard. Aguide groove is formed in the installation frame. A wiping device body is movably installed on the guide groove, and a rack is installed on the side, close to the blackboard, of the wiping device body. Moreover, the rack is in engaged transmission with a plurality of dust suction devices installed at the lower end of the installation frame. A detachable chalk manufacturing device is further arranged on one side of the installation frame, and a pressing device is arranged at the upper end of the chalk manufacturing device. According to the multi-functional blackboard wiping device provided by the invention, power generated through movement of the wiping device body is adopted to drive the dust suction devices and the pressing device at the same time.Dust can be sucked and further collectedinto the chalk manufacturing device, and the pressing device can be used for extruding the dust, so that the dust is blocked, and chalk manufacturing can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of teaching utensils and blackboard cleaning, and in particular relates to a multifunctional blackboard wiping device. Background technique [0002] Blackboard eraser is an indispensable teaching aid in our daily study, and ordinary blackboard eraser also has its inevitable disadvantages, that is, chalk dust will float randomly during use, and it will inevitably be inhaled into the lungs by teachers or students. And the blackboard eraser is not convenient enough for wiping the upper blackboard, therefore, it is worthy of our research for the improvement of the existing blackboard wiping device. [0003] For example, a Chinese patent discloses a blackboard eraser, [Application No.: 201610644384.X], which includes an upper rail, a lower rail, a frame, a collection box, a dust pipe and a dust wiping mechanism; the frame is slidably installed on the upper rail and the lower rail to slide along the length dire...
