Description

Novel blackboard eraser
The utility model relates to novel 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 21/00.
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 novel blackboard eraser, also once designed many outstanding technical schemes.As being declared by Zhao Weiguang of the Decree of Patent Office of China in 1996, Granted publication number is CN2233323Y, and China Patent No. (ZL) is: 95213178.No. 1 utility model title is the utility model patent of " band dust-collecting cup chalk dust ledge ", 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 chalk dust troughed belt collection cloth cup effectively.But still have some deficits, it also is difficult to solve the problem that can reduce chalk dust when erasing the board.
The purpose of this utility model is to provide a kind of novel blackboard eraser.Can reduce the problem of chalk dust when erasing the board with solution.
The purpose of this utility model is achieved in that the novel blackboard eraser of this utility model.Mainly constitute by motor, switch, box body, lead, fan, handle, battery case, felt layers, lid.Its major part motor, switch, lead, fan are by selecting for use on the market.Its battery case, box body are long body shape, make material with plastics, through the hot forming processing and manufacturing.Its felt layers is a rectangular shape, makes material with felt, through shearing processing and manufacturing.Its lid is a rectangular shape, makes material with plastics, through the hot forming processing and manufacturing.The fan of its leaf shape of spiral adopts the axle coupling method to be installed on the motor of cylindrical shape.Form the shaft coupling structure of a "T"-shaped shape.The motor of its cylindrical shape adopts the screw attachment method to be installed in the box body of rectangular shape.Form the screw attachment structure of a rectangular shape.The lid of its rectangular shape adopts the axle coupling method to be installed on the box body of rectangular shape.Form the shaft coupling structure of a rectangular shape.The battery case of its rectangular shape adopts adhesive method to be installed in the box body of rectangular shape.Form the adhesive structure of a rectangular shape.Its battery case acts on fan by motor.Thereby make fan satisfy the requirement that can suck chalk dust.Its handle acts on felt layers by box body.Thereby make felt layers finish the task that can erase the board.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with the original blackboard that the sucking chalk powder device is arranged or the cleaning device technology of slabstone;
The first, because the utility model has designed fan in technical scheme, so solved the problem that can absorb chalk dust;
The second, because the utility model has designed box body in technical scheme, so solved the chalk dust of can packing into, the problem of can pack into motor, battery case;
The 3rd, because the utility model has designed felt layers in technical scheme, so solved the problem that can wipe chalk dust.Thereby just can more effectively solve the problem that can reduce chalk dust when erasing the board.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the general structure schematic diagram of novel blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 motor, 2 switches, 3 box bodys, 4 leads, 5 fans, 6 handles, 7 battery cases, 8 felt layers, 9 lids
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, novel blackboard eraser of the present utility model.Mainly constitute by motor 1, switch 2, box body 3, lead 4, fan 5, handle 6, battery case 7, felt layers 8, lid 9.Its major part motor 1, switch 2, lead 4, fan 5 are by selecting for use on the market.Its battery case 7, box body 3 are long body shape, make material with plastics, through the hot forming processing and manufacturing.Its felt layers 8 is rectangular shape, makes material with felt, through shearing processing and manufacturing.Its lid 9 is rectangular shape, makes material with plastics, through the hot forming processing and manufacturing.The fan 5 of its leaf shape of spiral adopts the axle coupling method to be installed on the motor 1 of cylindrical shape.Form the shaft coupling structure of a "T"-shaped shape.The motor 1 of its cylindrical shape adopts the screw attachment method to be installed in the box body 3 of rectangular shape.Form the screw attachment structure of a rectangular shape.The lid 9 of its rectangular shape adopts the axle coupling method to be installed on the box body 3 of rectangular shape.Form the shaft coupling structure of a rectangular shape.The battery case 7 of its rectangular shape adopts adhesive method to be installed in the box body 3 of rectangular shape.Form the adhesive structure of a rectangular shape.Its battery case 7 acts on fan 5 by motor 1.Thereby make fan 5 satisfy the requirement that can suck chalk dust.Its handle 6 acts on felt layers 8 by box body 3.Thereby make felt layers 8 finish the task that can erase the board.So just realized the purpose of this utility model.Thereby just can solve the problem that can reduce chalk dust when erasing the board.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if erase the board, can Closing Switch 2, make battery case 7 give motor 1 power supply through lead 4, motor 1 drives fan 5 rotations, like this, and when erasing the board, felt layers 8 is wiped letter written with chalk, and fan 5 sucks chalk dust in the box body 3, has reduced chalk dust.
Embodiment 2, in force, if the chalk dust in the box body 3 is too many, influenced pick-up performance of the present utility model, can open lid 9, the chalk dust in the box body 3 is poured out covered lid 3 again, so just can continue to have used.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with plastics, felt, utilize the basic equipment of blackboard eraser processing factory, take hot forming, shear and produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
