Abstract
The utility model relates to a dustproof blackboard eraser which comprises a felt body and a shell which are connected together. The two longitudinal sides of the felt body are respectively provided with a soft baffle, and a dismountable dust collecting case is arranged at the lower part of the shell and the felt body. When the dustproof blackboard eraser is used for wiping a blackboard, chalk ash is blocked by the baffle, falls into the dust collecting case and can not float towards two sides so as to avoid pollution, health is not influenced, and cleaning is convenient.
Description
Technical field
The utility model relates to the daily living article field, is specifically related to a kind of dustproof blackboard eraser.
Background technology
In daily teaching and office, often need to use blackboard and chalk, during letter written with chalk on blackboard wiping, employed blackboard eraser is many with felt or sponge and the blackboard mantle friction dry linting writing of making a return journey.Can produce a large amount of chalk dusts during wiping, and the chalk dust particle is little, very light weight swims in the air easily, can be had a negative impact by the human body suction; And drop in corner and slit, also be not easy the cleaning.
If can reduce descending slowly and lightly of chalk dust with wet cloth wiping, but be not easy to wipe clean, and need often to clean wet cloth.
Therefore need a kind of blackboard eraser, can solve the problem that dust descends slowly and lightly in the wiping process.
The utility model content
The utility model aims to provide a kind of dustproof blackboard eraser.
Its technical scheme is: a kind of dust-proof blackboard eraser, comprise the felt body 2 and the shell 1 that link together, and respectively be provided with a soft baffle plate 3 in the vertical both sides of felt body, and be provided with a dismountable dust-collecting box 4 in the bottom of shell and felt body.
Baffle length and outer cover length coupling, the thickness of width and felt body adapts;
The length and the shell of dust-collecting box adapt, thickness be complementary with the integral thickness of felt body and shell; The dust-collecting box upper opening forms dust collecting opening 41.
This dust-proof blackboard eraser, when blackboard wiping, chalk dust is stopped by baffle plate, can not waft to both sides; And can fall into the dust-collecting box of bottom from dust collecting opening along the slit of baffle plate and felt body.Use the removable dust-collecting box cleaning down in back dust wherein.And, because baffle plate is a soft material, can scratch blackboard surface.
This dust-proof blackboard eraser is simple in structure, and cost is low, can avoid chalk dust to fly upward, and avoids polluting, and is not unhealthful, and cleaning is convenient.

The specific embodiment
A kind of dust-proof blackboard eraser as shown in Figure 1 to Figure 3, comprises the felt body 2 and the shell 1 that link together, respectively is provided with a soft baffle plate 3 in the vertical both sides of felt body, and is connected a dismountable dust-collecting box 4 in the bottom of shell and felt body.
Baffle length and outer cover length coupling, the thickness of width and felt body adapts;
The length and the shell of dust-collecting box adapt, thickness be complementary with the integral thickness of felt body and shell; The dust-collecting box upper opening forms dust collecting opening 41.
This dust-proof blackboard eraser, when blackboard wiping, chalk dust is stopped by baffle plate, can not waft to both sides; And can fall into the dust-collecting box of bottom from dust collecting opening along the slit of baffle plate and felt body.Use the removable dust-collecting box cleaning down in back dust wherein.
