Abstract

The invention provides a solar semi-automatic dust suction blackboard eraser, belongs to the technical field of teaching aids and aims at solving the problem that an automatic dust removal and dust suction integrated blackboard eraser does not exist in the prior art. A solar photovoltaic cell panel is connected with a controller, the controller is connected with a quick charge socket through a power transmission line, and a storage battery is arranged in a blackboard eraser housing, connected with the quick charge socket and connected with a motor. The motor is connected with a gear drive speed-reducing mechanism through a coupler, a set of fan blades is fixed to two driven gear shafts of the gear drive speed-reducing mechanism respectively, wiping discs are fixed to the outer ends of the driven gear shafts and arranged outside the open end of the blackboard eraser housing, and small holes are formed in the disc faces of the wiping discs. A pull-out type dust box is arranged between the two driven gear shafts of the gear drive speed-reducing mechanism, the driven gear shafts are sleeved with sleeves annularly, and the sleeves are fixed to an obliquely-arranged dust filtration gauze element assembly. The solar semi-automatic dust suction blackboard eraser is used for teaching and has an automatic dust removal and suction function.

Description

technical field [0001] The invention relates to a blackboard eraser and belongs to the technical field of teaching appliances. Background technique [0002] "A piece of chalk, a three-foot podium", this is a sincere compliment to teachers. As everyone knows, behind the praise, there are many hidden worries. The "chalk syndrome" brought by blackboard writing has become the number one health hazard for teachers and students. Teachers use chalk to write on the blackboard all the year round, and wipe it with traditional blackboard eraser, which will bring the following disadvantages: [0003] 1. In the process of wiping the blackboard, teachers and students will involuntarily "inhale" a large amount of dust into their bodies, which is prone to respiratory diseases. However, students have been in contact with chalk dust for a long time and are vulnerable to secondary dust in the classroom. The harm they suffer is even more serious than that of teachers. It takes at least 16 y...
