Abstract
The utility model relates to an electrostatic eraser for blackboard, pertaining to a writing or plotting apparatus in the printing subsection, operational transportation section as classified by the International Patent Classification (IPC); and to the art of the group of cleaning devices for blackboards or slates in the subcategory of writing or plotting supplies and auxiliary supplies for writing and plotting in the category of office supplies with Category No. B43L21/00. The utility model consists of an eraser, a switch, a wire, a circuit, a bolt, a steel sheet, a bolt, a dust container and a battery case, characterized in that the circuit board is arranged on the internal wall of the eraser, and is an electrostatic eraser for blackboard with high value of practicality.
Description
The utility model relates to the static blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article, the assistant product group of writing or draw, the cleaning device technical group field of blackboard or slabstone.Classification number is B43L21/00.
At present, the technology about the cleaning device of blackboard or slabstone existing and that once had was all done very fruitful effort to the demand of static blackboard eraser, also once designed many outstanding technical schemes.As being declared by Liu Fengwen of the Decree of Patent Office of China in 1996, Granted publication number is CN2234867Y, and China Patent No. (ZL) is: No. 95205328.4 utility model title is the utility model patent of " dustproof blackboard eraser ", the technical scheme that is adopted.Cleaning device technical elements at blackboard or slabstone is a routine of great value invention, and it has solved blackboard eraser dustproof problem effectively.But still have some deficits the too many problem of chalk dust when its also very difficult solution traditional blackboard erases the board.
The purpose of this utility model is to provide a kind of static blackboard eraser.The too many problem of chalk dust when erasing the board to solve traditional blackboard.
The purpose of this utility model is achieved in that the static blackboard eraser of this utility model.Mainly by blackboard eraser, switch, lead, circuit board, bolt, steel disc, bolt, deposit grey box, battery case, bolt and constitute.Its switch, lead, circuit board, bolt are by selecting for use on the market.Its blackboard eraser is a rectangular shape, with aluminium, cotton material, through the five metals processing and manufacturing.Its steel disc is a rectangular shape, uses ferrous materials, through the die-casting process manufacturing.Its battery case is a rectangular shape, uses plastic material, through the injection moulding processing and manufacturing.The flatiron method was installed in an end position of lead during switch adopted, and constituted Welding Structure, and function has been the effect of control power supply.Circuit board adopts the bolt method of attachment to be installed in the inner wall position of blackboard eraser, constitutes the convex shape overlay structure, and function has been the control circuit function.Steel disc adopts the bolt method of attachment to be installed in the groove location of blackboard eraser, constitutes the convex shape overlay structure, and function has been to produce static to inhale the dust effect.Battery case adopts the bolt method of attachment to be installed in the inner wall position of blackboard eraser, constitutes the convex shape overlay structure, and function has been the effect of discharge pond.Bolt and bolt adopt screw method to be installed in each hole site of blackboard eraser, constitute the convex shape penetrant structure, and function has been to fix each parts effect.Lead adopts the electric iron method to be installed in the binding post position of circuit board, battery case, steel disc, constitutes Welding Structure, and function has been an electric action.Deposit grey box adopt the method that stretches be installed in blackboard eraser below, constitute the Sheng ash structure of rectangular shape, function has been to contain grey effect.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared two advantages and improvement with the original blackboard or the cleaning device technology of slabstone;
The first, because the utility model designed the circuit that can produce static in technical scheme, so dust can be attracted to a place rather than fly around;
The second, because the utility model designed in technical scheme and deposit grey box,, when having expired dust outwelled and get final product so dust can be put together; Thereby the too many problem of chalk dust when just can more effectively solve traditional blackboard and erase the board.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the internal structure schematic diagram of static blackboard eraser of the present utility model;
Fig. 2 is the main TV structure schematic diagram of static blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 blackboard eraser, 2 switches, 3 leads, 4 circuit boards, 5 bolts, 6 steel discs, 7 bolts 8 are deposited grey box 9 battery cases 10 bolts
In the optimum implementation of static blackboard eraser of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, static blackboard eraser of the present utility model.Mainly by blackboard eraser 1, switch 2, lead 3, circuit board 4, bolt 5, steel disc 6, bolt 7, deposit grey box 8, battery case 9, bolt 10 and constitute.The flatiron method was installed in an end position of lead 3 during switch 2 adopted, and constituted Welding Structure, and function has been the effect of control power supply.Circuit board 4 adopts the bolt method of attachment to be installed in the inner wall position of blackboard eraser 1, constitutes the convex shape overlay structure, and function has been the control circuit function.Steel disc 6 adopts the bolt method of attachment to be installed in blackboard eraser 1 groove location, constitutes the convex shape overlay structure, and function has been to produce static to inhale the dust effect.Battery case 9 adopts the bolt method of attachment to be installed in the inner wall position of blackboard eraser 1, constitutes the convex shape overlay structure, and function has been the effect of discharge pond.Bolt 5, bolt 7 and bolt 10 adopt screw method to be installed in each hole site of blackboard eraser 1, constitute the convex shape penetrant structure, and function has been to fix each parts effect.Lead 3 adopts the electric iron method to be installed in the binding post position of circuit board 4, battery case 9, steel disc 6, constitutes Welding Structure, and function has been an electric action.Deposit grey box 8 adopt the method that stretches be installed in blackboard eraser 1 below, constitute the Sheng ash structure of rectangular shape, function has been to contain grey effect.
Its dynamic structure: in force:
According to the electrotechnics principle, its steel disc 6 acts on battery case 9 by electric wire 3, thereby finishes the task of producing static.Its steel disc 6 acts on blackboard eraser 1 by bolt 7, thereby finishes the task of attracting dust.So just realized the purpose of this utility model.Thereby the too many problem of chalk dust when just can solve traditional blackboard and erase the board.
Below by using method, the utility model is done more detailed description:
The static blackboard eraser of this utility model is work like this:
In use, when erasing the board, hold blackboard eraser and press the on-off circuit connection, the dust that generation static wiping board falls down is dropped to by electrostatic attraction to be deposited in the grey box, according to the electrotechnics principle, its steel disc 6 acts on battery case 9 by electric wire 3, thereby finishes the task of producing static.Its steel disc 6 acts on blackboard eraser 1 by bolt 7, thereby finishes the task of attracting dust.
Realize that preferred plan of the present utility model is is material with iron and steel, plastics, utilize the basic equipment of small-sized five metals factory, take to produce by batch in batches, the demand with supply teacher circle so just can realize practical value of the present utility model and economic worth better.
