Abstract

The invention provides a solar blackboard brush, belongs to the technical field of machinery, and solves the problem that in the prior art, utilization is inconvenient. The solar blackboard brush comprises a shell of which the interior is a cavity, and the shell is cuboid-shaped; bristles are fixedly connected to one side of the shell; a partition is arranged in the shell; the shell is divided into upper and lower adjacent chambers, namely, an upper chamber and a lower chamber, through the partition; fans and a filter assembly are connected in the lower chamber; batteries are connected in theupper chamber; the batteries are connected with the fans; an inlet and an outlet which communicate with an inner cavity of the lower chamber are formed in the lower chamber; the filter assembly is positioned at the inlet; and the outlet is positioned in the side part of the shell. The solar blackboard brush is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a solar blackboard brush. Background technique [0002] With the development of the times, students now have a better learning environment than before, such as more beautiful classrooms, more comfortable tables and chairs, air conditioners that can adjust the indoor temperature, and more advanced teaching equipment. [0003] But, the school of overwhelming majority still uses blackboard now, needs to write with chalk, the blackboard that blackboard eraser wipes. Therefore, many students will have troubles with chalk dust. During the teaching process, the chalk dust in the air will not only be inhaled, but can even be seen, which will have a great impact on the students' physiology and psychology, thereby affecting the quality of learning. [0004] The harm of chalk dust to the human body is most common in the lungs. During the teaching process, chalk dust is easily inhaled into ...
