Description
The utility model relates to electric dust absorption blackboard eraser.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, the big class of office appliance, write or drawing article, the assistant product group of writing or draw has the blackboard of sucking chalk powder device or the cleaning device technical group field of slabstone.Be numbered B43L 21/02.
At present, the technology about the cleaning device of blackboard that the sucking chalk powder device is arranged or slabstone existing and that once had was all done very fruitful effort to people in the demand of using blackboard eraser wiping chalk dust, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China on the 10th July in 1996 by Liu Zhaoyou, Granted publication number is CN2230668Y, China Patent No. (ZL) is: No. 95223215.4 utility model title is the utility model patent of " closed control of dust blackboard eraser ", the technical scheme that is adopted, cleaning device technical elements at blackboard that the sucking chalk powder device is arranged or slabstone is a routine of great value invention, and it has solved the problem of enclosed dust suction effectively.But still have some deficits, it also is difficult to solve simple in structure, easy to use, automatization level height, the fireballing problem of dust suction.
The purpose of this utility model is to provide a kind of electric dust absorption blackboard eraser, and is simple in structure to solve, easy to use, automatization level height, the fireballing problem of dust suction.
The purpose of this utility model is achieved in that this utility model electric dust absorption blackboard eraser.Mainly constitute by battery case lid, battery case, grey lid, grey box, ash absorbing hole, hair wiping, dust catcher, switch, lead, blackboard eraser body.Its major part hair wiping, dust catcher, switch, lead are by selecting for use on the market.Battery case, battery case lid, grey box, the compression molding manufacturing of hard plastic material of grey lid.Main body of the present utility model is the blackboard eraser body; The blackboard eraser body is wiped by grey box, dust catcher, battery case and the hair of peace on it and is formed; The battery case that hair is wiped is pacified built in the bottom of blackboard eraser body, and a mao wiping is used for wiping chalk dust, smears peace at hair and is shaped on ash absorbing hole, and the effect of ash absorbing hole is to suck to pacify on the battery case of chalk dust to be shaped on battery case lid, changes battery usefulness in order to get; The middle part of the blackboard eraser body of dust catcher peace between grey box and hair wiping, dust catcher links to each other with battery case with lead by switch, it is the main part of blackboard eraser body, the dust catcher peace is below grey box, and communicate with grey box, make the chalk dust that is sucked by it enter into grey box, peace is shaped on grey lid on the grey box, is used for conveniently the chalk dust in the grey box being toppled over out.So just realized the purpose of this utility model.
The utility model has been compared two advantages and improvement with the technology of the cleaning device of original blackboard that the sucking chalk powder device arranged or slabstone;
The first, because the utility model has designed dust catcher in technical scheme, so solved the power resources that absorb chalk dust effectively;
The second, because the utility model has designed grey lid in technical scheme, so solved the problem of toppling over chalk dust effectively.Thereby just can more effectively solve simple in structure, easy to use, automatization level height, the fireballing problem of dust suction.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1: the overall structure schematic diagram that is the utility model electric dust absorption blackboard eraser:
The numbering of parts explanation in the schematic diagram: the grey box of the grey lid of (1) battery case lid (2) battery case (3) (4) (5) ash absorbing hole (6) hair is wiped (7) dust catcher (8) switch (9) lead (10) blackboard eraser body
Below in conjunction with accompanying drawing, the utility model is described further:
