The utility model is simple in structure, easy to use, because blackboard eraser can hold a certain amount of chalk dust, as long as it is several down to stick on the latticed bushing that the blackboard eraser of dust is placed on box body opening part grazing back and forth (or bump and knock) during use, dust can be fallen in the dust fall box one after another, again toward several times of latticed bushing grazing, twice or thrice just can reach the purpose of sanitation and hygiene so repeatedly after erasing the board again.After class chalk dust is outwelled in the extraction of drawer type dust fall box and got final product.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is a kind of Facad structure schematic diagram of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the cutaway view of Figure 1A-A direction.

Wherein: 1 loam cake, 2 box bodies (also claiming shell body), 3 latticed bushings, 4 ash holes, 5 drawer type dust fall boxes, 6 chalk holders, 7 blackboard erasers.

With reference to accompanying drawing, the utility model also can have following technical characterictic when specific design is made:

One, the bottom enclosure at box body 2 can directly be made for a dust fall box, can be furnished with a movable sealing lid (accompanying drawing slightly) in ash hole.

Two, described latticed bushing 3 can be that wire is made, and also can be injection mo(u)lding.

Three, also can set up the chalk holder 6 of a dress chalk in a side of box body 2.

When the utility model was made in specific design, its box body bottom width can be made into and is slightly less than the width that ash-pit is contained in blackboard bottom, ash collecting box directly can be placed on like this use on the Sheng ash-pit of blackboard very convenient.Appearance of the present utility model also can be made into the shape and structure (accompanying drawing slightly) that shape (see figure 2) face shaping wide at the top and narrow at the bottom also can be made into the truck of create an aesthetic feeling or spends blue type.Perhaps will make elephant or other animal-shaped shapes (accompanying drawing slightly) as the box figure shape of shell.
