Description
(1) technical field:
The utility model relates to environment-friendly dust-proof eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation, Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; Write or draw assistant product group, blackboard or slabstone technical group field.
(2) background technology:
At present, the technology about blackboard or slabstone group existing and that once had was all done very fruitful effort to the demand of environment-friendly dust-proof eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Liu Guojia, Granted publication number is CN2216933Y, China Patent No. (ZL) is: No. 94218538.2 utility model patent title is the utility model patent of " blackboard wiper ", the technical scheme that is adopted.The technical elements of blackboard or slabstone group is a routine of great value invention, and it has solved the technical problem that wiper erases the board effectively.But still have some deficits, it also is difficult to solve, and dust is many, the technical problem of harm teachers ' health.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of environment-friendly dust-proof eraser.Dust is many to solve, the technical problem of harm teachers ' health.
The environment-friendly dust-proof eraser that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: bristle, shell, pillar, cap nut, base, switch, battery, electric wire, motor, flabellum constitute.Its major part motor, flabellum are selected for use by market.Its bristle is a rectilinear form, is material with the fiber, through the pulling-down processing and manufacturing.Its shell is a cylindrical shape, is material to mould firmly, through the cold forming processing and manufacturing.Its base is a rectangular shape, is material to mould firmly, through the processing and forming manufacturing.
In shape, structure and combination thereof, the total essential features of environment-friendly dust-proof eraser of the present utility model and immediate prior art is: an end position adhesion of bristle is connected the surface location of shell, be combined into the fixed structure of circular spray nozzle type shape, function has been the effect of wiping writing.In shape, structure and combination thereof, the environment-friendly dust-proof eraser of the present utility model technical characterictic different with immediate prior art is: position, the back screw of shell is connected the apical position of pillar, the tip position screw of base is connected the bottom position of pillar, be combined into the fixed structure of blackboard eraser shape, function has been the effect of holding.The end positions lead of battery is connected the end positions of motor, and an end position screw of motor is connected the bottom position of flabellum, is combined into the bascule of hair-dryer shape, and function has been the effect of dust suction.The solution dust of so just having realized environment-friendly dust-proof eraser of the present utility model is many, the purpose of the technical problem of harm teachers ' health.
The beneficial effect of the environment-friendly dust-proof eraser of utility model is: dust is many in order to solve, the technical scheme that technical problem adopted of harm teachers ' health has been compared a place's advantage and an improvement with existing with the technology about blackboard or slabstone group that once had for the utility model:
First, because the end positions lead that has designed battery in the technical scheme of environment-friendly dust-proof eraser of the present utility model is connected the end positions of motor, one end position screw of motor is connected the bottom position of flabellum, be combined into the bascule of hair-dryer shape, so technical problem that can easier solution dust suction.

(5) specific embodiment:
Below in conjunction with accompanying drawing, be that the optimal way that realization solves the technical scheme that dust technical problems many, that endanger teachers ' health take is described further to environment-friendly dust-proof eraser of the present utility model:
Its static structure: please join accompanying drawing: as shown in the figure, environment-friendly dust-proof eraser of the present utility model mainly is made of bristle 1, shell 2, pillar 3, cap nut 4, base 5, switch 6, battery 7, electric wire 8, motor 9, flabellum 10.Its main its major part motor 9, flabellum 10 selected for use by market.Its bristle 1 is a rectilinear form, is material with the fiber, through the pulling-down processing and manufacturing.Its shell 2 is cylindrical shapes, is material to mould firmly, through the cold forming processing and manufacturing.Its base 5 is rectangular shapes, is material to mould firmly, through the processing and forming manufacturing.
In shape, structure and combination thereof, the total essential features of environment-friendly dust-proof eraser of the present utility model and immediate prior art is: an end position adhesion of bristle 1 is connected the surface location of shell 2, be combined into the fixed structure of circular spray nozzle type shape, function has been the effect of wiping writing.In shape, structure and combination thereof, the environment-friendly dust-proof eraser of the present utility model technical characterictic different with immediate prior art is: position, the back screw of shell 2 is connected the apical position of pillar 3, the tip position screw of base 5 is connected the bottom position of pillar 3, be combined into the fixed structure of blackboard eraser shape, function has been the effect of holding.The end positions lead of battery 7 is connected the end positions of motor 9, and an end position screw of motor 9 is connected the bottom position of flabellum 10, is combined into the bascule of hair-dryer shape, and function has been the effect of dust suction.
Below by using method, further set forth the dynamic structure relation of this practical environment-friendly dust-proof eraser: in use, when needs erase the board, principle according to electric power, at first add entry, open switch 6 then, flabellum 10 is rotated, the dust suction that erases the board then again, thus the task of dust suction environmental protection finished.
Realize preferred plan of the present utility model be with mould firmly, metal is material, utilize the basic equipment of stationery factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of environment-friendly dust-proof eraser of the present utility model better with the demand of supply culture and education circle.
