Abstract

A dust-proof blackboard eraser comprises an elliptic plastic casing (1) and a sponge brush, wherein a lap of fuzz brush (3) is arranged on the outer circle of the plastic casing (1); the sponge brush comprises a large sponge brush (4) and a small sponge brush (5), which are concentric and take the shape of elliptic rings; the large sponge brush (4) and the small sponge brush (5) are slightly lower than the fuzz brush (3), so as to prevent dust falling from the blackboard eraser; certain space used for storing the fallen chalk dust is formed among the large sponge brush (4), the small sponge brush (5) and the fuzz brush (3); a magnet (6) is fixed inside the small sponge brush (5), so that the blackboard eraser can be adsorbed on the blackboard at random; and a handle (2) is arranged on the plastic casing (1) for user convenience.

Description

Dust-proof blackboard eraser

Technical field

The utility model relates to a kind of blackboard eraser, a kind of dust-proof blackboard eraser of more specifically saying so.

Background technology

Blackboard eraser is the article that often use in the teaching process, common blackboard eraser can cause chalk dust to fly away in air when erasing the board now, these dust are sucked in the lung by the academics and students, influence their healthy, of long duration can cause breathing problem, serious even can cause pneumoconiosis.Simultaneously present blackboard eraser is taken and is held also very inconvenience, usually can make both hands be stained with chalk dust.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art and defective, provides a kind of convenience to take the dust-proof blackboard eraser of holding.

To achieve these goals, the technical solution of the utility model is: dust-proof blackboard eraser, comprise oval-shaped plastic casing and sponge brush, the outer ring of described plastic casing is provided with a circle fine hair brush, and described sponge brush is two big sponge brushes of concentric oval ring and little sponge brush.

Described big sponge brush and little sponge brush are brushed a little less than fine hair, and all have certain interval between the three.

Described little sponge brush center fixed has a magnet.

Described plastic casing is provided with handle.

Pass through technique scheme, the beneficial effects of the utility model are: between the two circle sponge brushes certain interval is arranged in the utility model 1., store the chalk dust that brush falls, while fine hair brush is higher than sponge brush and can prevents that dust from flying away out in blackboard eraser, prevent that the academics and students from sucking too much dust, guaranteed the health cleaning of their work and study environment.2. the utility model is provided with a handle, makes it more convenient to operate, and the situation of having avoided both hands to be stained with chalk dust takes place.3. the utility model is provided with a magnet simultaneously, can be adsorbed on the blackboard when not using, and has solved blackboard eraser and has deposited the problem of inconvenience.
