[0018] like Figure 1-4 As shown, the blackboard eraser storage box of the utility model comprises a placement box 1 and a dust collecting box 2. The placement box 1 is provided with a partition 12 for dividing the inner cavity of the placement box 1 into two left and right placement cavities 11. A grille hole 13 is formed at the bottom of each placement cavity 11. The placement box 1 is used to be fixed on a wall. The upper end of the dust collecting box 2 is detachably connected to the lower end of the placement box 1. The dust collecting box 2 is used to collect chalk foam from the placement cavity 11. A plurality of convex ribs 14 are arranged on the inner wall of the front side of each placement cavity 11 at intervals from top to bottom. The convex ribs 14 are used to scrape off the chalk foam on the blackboard eraser.
[0019] When the utility model is used, the placement box is fixed on the wall. When the chalk dust on the blackboard eraser needs to be cleaned, the blackboard eraser is inserted into one of the placement cavities, and the side of the blackboard eraser with the chalk dust adhered to it faces the convex rib located at the front side of the placement cavity. Then, the blackboard eraser is moved up and down to make the convex rib and the side of the blackboard eraser with the chalk dust adhered to it generate friction. At this time, the chalk dust adhered to the blackboard eraser can be scraped off by the convex rib, and finally the chalk dust can fall into the dust collection box through the grille hole and be collected by the dust collection box. Since the utility model is provided with two placement cavities, two blackboard erasers can be placed at the same time.
[0020] The vertical cross-section of each convex rib 14 is a serrated structure; by adopting this structure, when the side of the blackboard eraser with chalk foam adhered thereto rubs against the corresponding convex ribs on the front side of the placement cavity, the convex ribs with a serrated cross-section can more easily scrape off the chalk foam on the blackboard eraser, that is, the effect of removing the chalk foam on the blackboard eraser can be improved.
[0021] Each convex rib 14 extends to the left and right ends of the corresponding placement cavity 11; by adopting this structure, when the side of the blackboard eraser with chalk foam sticking to it rubs against the several convex ribs on the front side of the corresponding placement cavity, it can be ensured that the side of the blackboard eraser with chalk foam sticking to it is reliably in contact with the several convex ribs, thereby improving the effect of removing chalk foam on the blackboard eraser.
[0022] An upwardly extending extension section 15 is provided at the upper end of the rear side of the placement box 1, and two left-right symmetrical fixing holes 16 are provided on the extension section 15. The placement box 1 is fixed to the wall by screws passing through the fixing holes 16; by adopting this structure, the placement box can be conveniently and reliably fixed to the wall.
[0023] The upper end of the dust collecting box 2 abuts against the lower end of the placement box 1, and a "U"-shaped convex edge 21 with a rear opening is provided at the outer edge of the upper end of the dust collecting box 2, and the convex edge 21 is used to be mounted on the outer wall of the lower end of the dust collecting box 2 and tightly matched with the outer wall of the dust collecting box 2; after adopting this structure, when the upper end of the dust collecting box is connected to the lower end of the placement box, the upper end of the dust collecting box can abut against the lower end of the placement box, and the convex edge can be mounted on the outer wall of the lower end of the dust collecting box and tightly matched with the outer wall of the dust collecting box, so that the dust collecting box can be conveniently connected to the placement box, and when the dust collecting box is pulled downward, the convex edge can be separated from the placement box, thereby realizing the separation of the dust collecting box and the placement box.
[0024] The dust box 2 is made of transparent plastic material; by using transparent plastic to make the dust box, the amount of chalk dust collected in the integrated box can be easily observed. When there is a lot of chalk dust in the dust box, the dust box can be removed from the lower end of the placement box and the chalk dust in the dust box can be dumped.
[0025] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
