Abstract
The utility model relates to a dust absorption blackboard eraser comprising a door handle, a dust outlet, a wooden board, bristle, an air sac and a tube. The utility model is characterized in that the air sac is installed at the lower part of the door handle. The utility model is a dust absorption blackboard eraser with an excellent practicality.
Description
The utility model relates to dust absorption 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, big group of the cleaning device of blackboard or slabstone has the little technical group field of sucking chalk powder device.Classification number is B43L21/02.
At present, have now and big group of the cleaning device that once had, have the technology of the group of sucking chalk powder device that the demand of dust absorption blackboard eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.As declaring of the Decree of Patent Office of China in 1996 by Jia Tianjie, Granted publication number is CN2242799Y, China Patent No. (ZL) is: No. 95227380.2 utility model title is the utility model patent of " electric dust-less blackboard wiping ", the technical scheme that is adopted.Big group of the cleaning device of blackboard or slabstone, group's technical elements that the sucking chalk powder device is arranged is a routine of great value invention, and it has solved the problem that electric dust-less blackboard is wiped effectively.But still have some deficits, it also is difficult to the problem in the easy inspiration mouth of chalk dust when erasing the board that solves.
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.Problem when erasing the board in the easy inspiration mouth of chalk dust with solution.
The purpose of this utility model is achieved in that the dust absorption blackboard eraser of this utility model.Mainly by door handle, put dirt mouth, plank, bristle, air bag, pipe and constitute.Its door handle, air bag, pipe are by selecting for use on the market.Its plank is that hole shape is arranged in the cuboid, uses wood material, through the machining manufacturing.Its air bag is an elliptical shape, uses elastomeric material, moulds processing and manufacturing through watering.Door handle adopts bolt side's dirt method to be installed in the upper position of plank, constitutes shield fixed in shape structure, and function has been conveniently to take the blackboard eraser effect.Bristle adopts method of attaching to be connected the lower position of plank, constitutes turriform shape blackboard eraser structure, and function has been the effect of erasing the board.Air bag adopts method of attaching to be installed in the lower position of door handle, constitutes the elliptical shape fixed structure, and function has been to put into the dust effect.Pipe adopts method of attaching to be connected an end position of air bag, constitutes snakelike shape inflator structure, and function has been to transport the dust channel effect.So just realized the purpose of this utility model.
The advantage of utility model: big group of the cleaning device of the utility model and original blackboard or slabstone has group's technology of sucking chalk powder device to compare two advantages and improvement;
The first, because the utility model designed air bag in technical scheme, so can dust suction;
The second, because the utility model has designed pipe in technical scheme, so can transport ash; Thereby just can more effectively solve the problem in the easy inspiration mouth of chalk dust when erasing the board.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of dust absorption blackboard eraser of the present utility model;
Fig. 2 is the side-looking structural representation of dust absorption blackboard eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 door handle 2 is put dirt mouth 3 planks 4 bristles 5 air bags 6 pipes
In the optimum implementation of dust absorption 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, dust absorption blackboard eraser of the present utility model.Mainly by door handle 1, put dirt mouth 2, plank 3, bristle 4, air bag 5, pipe 6 and constitute.Door handle 1 adopts the bolt method to be installed in the upper position of plank 3, constitutes shield fixed in shape structure, and function has been conveniently to take the blackboard eraser effect.Bristle 4 adopts method of attaching to be connected the lower position of plank 3, constitutes turriform shape blackboard eraser structure, and function has been the effect of erasing the board.Air bag 5 adopts method of attaching to be installed in the lower position of door handle 1, constitutes the elliptical shape fixed structure, and function has been to put into the dust effect.Pipe 6 adopts method of attaching to be connected an end position of air bag 5, constitutes snakelike shape inflator structure, and function has been to transport the dust channel effect.
Its dynamic structure: in force:
According to the pressure principle, its air bag 5 acts on dust by pipe 6, thereby finishes the task of dust suction.So just realized the purpose of this utility model.Thereby just can solve the problem in the easy inspiration mouth of chalk dust when erasing the board.
Below by using method, the utility model is done more detailed description:
The dust absorption blackboard eraser of this utility model is work like this:
In use, when erasing the board, chalk dust falls.According to the pressure principle, its air bag 5 acts on dust by pipe 6, thereby finishes the task of dust suction.
Realize that preferred plan of the present utility model is is material with wood, utilize the basic equipment of blackboard eraser factory, take assembling to produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
