Abstract
The invention relates to a multifunctional blackboard eraser which comprises a brush and a fixing support. The brush is connected with the fixing support, the fixing support is positioned inside the brush body, an engine is arranged inside the brush body, a vortex type fan blade and a fan blade are respectively connected with two sides of the engine through rotating shafts, a filter is arranged on the brush body and connected with the brush body through the fixing support, the vortex type fan blade is connected with the fixing support, dust boards are arranged on the brush body in the positions close to the two sides of the brush, a battery box and a switch are arranged inside the brush body, and the switch is respectively connected with the battery box and the engine through wires. Because the structure is adopted, the engine can drive the brush and the fan blades to rotate only by powering on the switch, thereby achieving the effect of quickly cleaning the blackboard and collecting the dust.
Description
Technical field
The present invention relates to a kind of improvement of teaching aid, particularly a kind of multifunctional blackboard eraser.
Background technology
When existing blackboard eraser erased the board, chalk dust can fly upward everywhere, influences health.
Summary of the invention
Purpose of the present invention will provide a kind of multifunctional blackboard eraser exactly, and it can overcome above-mentioned the deficiencies in the prior art, and collection rotation, dust suction and filtering function are one, make blackboard eraser that chalk dust is flown upward everywhere, reaches to keep sanitary purpose.
