Description
The utility model relates to a kind of static 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 the demand of ash-collecting blackboard eraser, also once did many outstanding designs and scheme.As being declared by Liu Zhaoyou of the Decree of Patent Office of China in 1993, Granted publication number is CN2147974Y, and China Patent No. (ZL) is: No. 93227560.5 utility model title is the utility model patent of 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 double problem of collecting chalk dust function that has in the process of erasing the board effectively.But still have some deficits, it also is difficult to solve simpler, the more economical problem of control of dust wiping blackboard structure that makes.
The purpose of this utility model is to provide a kind of static blackboard eraser.Make simpler, the more economical problem of control of dust wiping blackboard structure with solution.
The purpose of this utility model is achieved in that a kind of static blackboard eraser of this utility model.Mainly constitute by attached plate, static bruss, steel wire, electrostatic fibre.The hard plastics casting processing and manufacturing of the attached plate of its major part.Static bruss electrostatic fibre and steel wire manufacturing.Blackboard eraser is made up of attached plate and static bruss two parts, and through cast molding, made by thinner steel wire and electrostatic fibre by static bruss by rigid plastics for attached plate, has the function of absorption dirt powder, can clean by water simultaneously.So just realized the purpose of this utility model.
The utility model has been compared an advantage 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 the electrostatic fibre brush of interior band steel wire in technical scheme.Thereby just can more effectively solve the problem that makes the control of dust wiping blackboard structure simpler, more economical.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1: be contour structures schematic diagram of the present utility model:
Fig. 2: be cross-sectional view of the present utility model:
The numbering of parts explanation in the schematic diagram: (1) attached plate (2) static bruss (3) steel wire (4) electrostatic fibre
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of static blackboard eraser of the utility model.Mainly constitute by attached plate (1), static bruss (2), steel wire (3), electrostatic fibre (4).The attached plate of its major part (1) hard plastics casting processing and manufacturing.Static bruss (2) electrostatic fibre and steel wire manufacturing.Blackboard eraser is made up of attached plate (1) and static bruss (2) two parts, and through cast molding, made by thinner steel wire (3) and electrostatic fibre (4) by static bruss (2) by rigid plastics for attached plate (1), has the function of absorption dirt powder, can clean by water simultaneously.So just realized the purpose of this utility model.Thereby just can solve the problem that makes the control of dust wiping blackboard structure simpler, more economical.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in use, if in the classroom, use this blackboard eraser of making by electrostatic fibre (4) to erase the board, then the situation that can avoid chalk dust to fly around is healthy in profit, simultaneously to teachers and students, this blackboard eraser hairbrush part is not yielding, and can wash by water.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with the electrostatic fibre, utilize the basic equipment of casting factory, take assembling to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
