Abstract

The utility model discloses a dust absorption blackboard eraser. A micro-motor (3) is fixed inside an eraser body (1), the micro-motor (3) is in driving connection with fan blades (4); a cavernous block (5) is arranged inside the eraser body (1); the eraser body (1) is provided with a vent hole (6) and a dust absorption hole (7); the dust absorption hole (7), the micro-motor (3), the fan blades (4), the cavernous block (5) and the vent hole (6) are sequentially arranged from the brushes(2) to the back side of the eraser body (1). The fan blades run under the driving of the micro-motor, absorb dust from the dust absorption hole, and blow to the cavernous block, dust is absorbed by the cavernous block, and the gas is blown out of the vent hole, thus efficiently solving the problem of a plurality of dust caused by the prior blackboard eraser in use.

Description

A kind of dust absorption blackboard eraser
Technical field
The utility model relates to a kind of blackboard eraser, particularly a kind of dust absorption blackboard eraser.
Background technology
In school, blackboard eraser is one of teachers' instrument commonly used.But traditional blackboard eraser can produce a large amount of dust in use, not only is unfavorable for health but also be unfavorable for health.
The utility model content
The utility model provides a kind of dust absorption blackboard eraser, solves the problem that traditional blackboard eraser can produce a large amount of dust in use.
In order to solve these technical problems, the utility model has adopted following technical scheme.
A kind of dust absorption blackboard eraser, comprise that a side has the blackboard eraser body of bristle, is characterized in that: in blackboard eraser body inside a micromachine is installed, micromachine is connected with flabellum; In blackboard eraser body inside sponge block is installed also; Also offer steam vent and air suction opening on the blackboard eraser body; Air suction opening, micromachine, flabellum, sponge block and steam vent, one side is arranged in order from the bristle one side direction blackboard eraser body back side.
