In technique scheme, described brush body portion is the sponge protruding block of multiple circle.
In technique scheme, described drawer type screen plate is provided with multiple filtering holes, is provided with drainage screen in filtering holes.
In technique scheme, described drawer type screen plate is externally provided with circular operating portion.
The greyish black blackboard eraser of the chargeable suction of this utility model, by arranging absorption small fan in the containing cavity of board body part, can be when brush body portion carries out wiping font, self-dust-suction hole sucks dust and carries out the filtration of dust granules to the drawer type screen plate in containing cavity, air-flow after filtration is discharged to described air-flow through hole, drawer type screen plate can carry out pull and be carried out outside board body part, is charged to charging module by charging inlet, it is achieved to repeat continual utilization simultaneously.So, reach to adsorb fast and effectively the dust wiped out, improve the beneficial effect of teachers and students' health of human body safety.
Accompanying drawing explanation
Fig. 1 is the chargeable suction of this utility model greyish black blackboard eraser schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, the greyish black blackboard eraser of the chargeable suction of one described in the utility model, including board body part 1, and being located at the brush body portion 2 of the lower surface of described board body part 1, in the present embodiment, described brush body portion 2 is the sponge protruding block of multiple circle, and is spaced setting.Described brush body portion 2 can also be general conventional bristle, does not tires out at this and states, can design according to actual needs.
The inside of described board body part 1 is provided with containing cavity 10, and the lower surface of described board body part 1 is provided with multiple air suction opening 11 between described brush body portion 2, and described air suction opening 11 connects with described containing cavity 10.It is easy to described dust enter in described containing cavity 10 from described air suction opening 11.
Being provided with fixed plate 12 in described containing cavity 10, described fixed plate 12 is provided with absorption small fan 3 and the charging module 4 being connected with described absorption small fan 3, and the side of described board body part 1 is provided with the charging inlet 13 being connected with described charging module 4.Described charging module 4 can be charged by described charging inlet 13, it is ensured that its enough electricity, make described absorption small fan 3 operate, suck dust in containing cavity 10 from described air suction opening 11.
The upper surface of described board body part 1 is provided with control switch 5 and is connected with described absorption small fan 3, is provided with drawer type screen plate 6 in described containing cavity 10, and described drawer type screen plate 6 is positioned at the lower section of described fixed plate 12.Described drawer type screen plate 6 is provided with multiple filtering holes 61, is provided with drainage screen 62 in filtering holes 61.Further, described drawer type screen plate 6 is externally provided with circular operating portion 63, facilitates drawer type screen plate 6 described in pull to be carried out, it is achieved recycling.
