Description

Chalk dust cleaning receiver

Technical field

The utility model belongs to teaching aid field, specifically a kind of chalk dust cleaning receiver.

Background technology

In daily teaching, under normal circumstances, after student or teacher wipe blackboard, chalk dust can adhere on blackboard eraser, if do not cleaned out, continuing use just can not be clean by blackboard eraser; And chalk dust also will fly upward everywhere, both contaminated environment, will impact the health of student and teacher again; Especially be sitting in front-seat classmate, the more chalk dust of inspiration.

When blackboard eraser sticks chalk dust, blackboard eraser often can be put into one by student or teacher to be had the place of corner angle to knock gently or rubs the chalk dust on blackboard eraser back and forth.But so, chalk dust still can disperse everywhere, be not easy to cleaning, also pollute the environment.

Utility model content

The purpose of this utility model is to provide a kind of chalk dust to clear up receiver.This chalk dust cleaning receiver has cleaning concurrently and collects the function of chalk dust, while ensureing that the chalk dust on blackboard eraser is cleaned out, does not pollute teaching environment again.

The purpose of this utility model is achieved through the following technical solutions:

The utility model comprises box and lower box, box and lower box mounted on top on this, and the bottom surface of described upper box is for ease of clearing up the grid of chalk dust.

Wherein: be provided with the collecting bag collecting chalk dust between described upper box and lower box, this collecting bag is arranged in described lower box, and the edge of opening of described collecting bag is enclosed within described lower box; The bottom of described upper box is provided with seam, and described upper box by this seam and described lower stacking cassette, and is located by described seam; Described lower box height is two times of upper box height.

Advantage of the present utility model and good effect are:

1. the utility model is divided into upper and lower two-layer box, and upper box is mainly used in clearing up chalk dust, and lower box can collect the chalk dust rubbed, and both ensure that the chalk dust on blackboard eraser is cleaned out, has avoided again chalk ash pollution teaching environment.

2. the utility model also can overlap collecting bag on lower box, collects full rear and need throw away collecting bag, convenient and healthy.

3. be provided with seam bottom upper box of the present utility model, be both convenient to stacking of upper and lower box, made again box put firmly.

4. upper box height of the present utility model is 1/2nd of lower box height, decreases making material, reduces cost.

Fig. 1 is one of perspective view of the present utility model;

Fig. 2 is perspective view two of the present utility model;

Fig. 3 is the perspective view that on lower box of the present utility model, cover has collecting bag;

Wherein: 1 is upper box, 2 is lower box, and 3 is collecting bag, and 4 is seam, and 5 is grid.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figures 1 to 3, the utility model comprises box 1 and lower box 2, and upper box 1 is identical with lower box 2 shape, and the present embodiment is oblong; Upper box 1 and lower box 2 mounted on top.For the ease of putting of upper box 1 and lower box 2, and the upper box 1 be placed on above lower box 2 is not dropped easily, be provided with seam 4 in the bottom of upper box 1, upper box 1 is stacked with lower box 2 by this seam 4, the bottom margin of upper box 1 is just buckled on lower box 2, and is located by seam 4.

The bottom surface of upper box 1 is for ease of clearing up the grid 5 of chalk dust, and be mainly used in clearing up chalk dust, be convenient to blackboard eraser and rub back and forth, namely chalk dust is fallen 2 li, lower box by grid 5 and collected.For the ease of clearing up the chalk dust in lower box 2, can be provided with the collecting bag 3 collecting chalk dust between upper box 1 and lower box 2, this collecting bag 3 is arranged in lower box 2, and the edge of opening of collecting bag 3 is enclosed within lower box 2, and upper box 1 can clamp collecting bag 3 after putting.So, by the chalk dust rubbed on blackboard eraser, namely drop in collecting bag 3, collect completely and just can directly collecting bag be thrown away.

Lower box 2 is highly two times of upper box 1 height, can save the material making upper box 1 like this, reduce costs, also make box 1 overlay securely on lower box 2.

The material of upper box 1 of the present utility model and lower box 2 can be wooden, and grid 5 can be steel mesh.If batch manufacturing, steel mesh also can change plastic grid into, again reduces cost.
