The purpose of the utility model provides a kind of dust absorption blackboard eraser that can stop chalk dust to fill the air the classroom.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of dust absorption blackboard eraser comprises wiping board, it is characterized in that: the wiping board front is connected with connection chamber, and connection chamber is a hollow, has grey hole on the wall of connection chamber, and the connection chamber front is equipped with snag, and snag was distributed in around the grey hole; Have on the wiping board and wear buttonhole, wear and be installed with in the buttonhole, be connected with pressing plate by an end of press button by press button; Pressing plate is positioned at connection chamber, and the pressing plate front is provided with plasticity and stores up grey capsule, and plasticity is stored up grey capsule and also is positioned at connection chamber; Plasticity is stored up on the wall of grey capsule and is had ash absorbing hole, ash absorbing hole with cross grey hole and communicate.
Use the utility model in the process that erases the board, can make chalk dust be inhaled into plasticity and store up grey capsule, thereby can stop chalk dust to fill the air through storing up grey capsule by press button extruding plasticity in the classroom.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing:
1, presses press button; 2, wear buttonhole; 3, wiping board; 4, pressing plate; 5, connection chamber; 6, plasticity is stored up grey capsule; 7, snag; 8, cross grey hole; 9, ash absorbing hole.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of dust absorption blackboard eraser, as shown in Figure 1, comprise wiping board 3, wiping board 3 fronts are connected with connection chamber 5, and connection chamber 5 is a hollow, has grey hole 8 on the wall of connection chamber 5, and connection chamber 5 fronts are equipped with snag 7, and snag 7 was distributed in around the grey hole 8; Have on the wiping board 3 and wear buttonhole 2; Wear and be installed with in the buttonhole 2 by press button 1, be connected with pressing plate 4 by an end of press button 1, pressing plate 4 is positioned at connection chamber 5; Pressing plate 4 fronts are provided with plasticity and store up grey capsule 6; Plasticity is stored up grey capsule 6 and also is positioned at connection chamber 5, and plasticity is stored up on the wall of grey capsule 6 and had ash absorbing hole 9, ash absorbing hole 9 with cross grey hole 8 and communicate.
The utility model is changed traditional in the past wooden structure on the basis of original blackboard eraser, utilize the characteristics of inner hollow, and a similar dust collector structure is installed in inside, is used for absorbing chalk dust.
When using the utility model to erase the board; To press by press button earlier, the air that plasticity is stored up in the grey capsule is caught up with only by pressing plate, unclamps by press button; Plasticity is stored up grey capsule and can slowly be restored to the original state; In this process, the chalk dust of the generation that erases the board can be inhaled into plasticity with air and store up in the grey capsule, thereby reaches the purpose of dust suction.Can plasticity be stored up grey capsule at a distance from a period of time and take off, pour out plasticity and store up the chalk dust in the grey capsule.
Use the utility model effectively to reduce chalk dust and in air, spread, both protected the environment in the classroom, reduced influence again SH.
