Description
(1) technical field:
The utility model relates to dust absorption blackboard 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; 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.
(2) background technology:
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 being declared by Cao Minghui of the Decree of Patent Office of China in 1996, Granted publication number is CN2219216Y, and China Patent No. (ZL) is: No. 95210622.1 utility model title is the utility model patent of " ash-collecting blackboard eraser ", 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 technical problem of blackboard eraser effectively.But still have some deficits, it is too many that it also is difficult to solve general blackboard eraser dust, the technical problem of contaminated environment.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust absorption blackboard eraser.Too many to solve general blackboard eraser dust, the technical problem of contaminated environment.
The dust absorption blackboard eraser that the technical scheme that the technical problems to be solved in the utility model adopted is achieved in that this utility model mainly by: felt, shell, wind wheel, motor, battery, cloth bag constitute.Its wind wheel, motor, battery are by selecting for use on the market.Its felt is a rectangular shape, uses batt material, through the braiding processing and manufacturing.Its shell is a rectangular shape, uses the steel material, through rolling processing and manufacturing.Its cloth bag is the ball shape, uses cloth material, through the braiding processing and manufacturing.
In shape, textural, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: the bonding forward position that is installed in shell of felt, constitute the rectangular shape combining structure, and function has been the effect of erasing the board.In shape, textural, the novel umbrella formula Air inflation rain cape of the present utility model technical characterictic different with immediate prior art is: the motor screw is fixedly mounted on the interior location of shell, constitutes
Combination of shapes structure, function have been that dynamic action is provided.The bonding lower right end position that is installed in shell of cloth bag constitutes " " combination of shapes structure, and function has been to collect the effect that dust is regularly removed.The wind wheel screw attachment is installed in the forward position of motor, constitutes " H " combination of shapes structure, and function has been the dust suction effect.The battery lead method of attachment is installed in the rear positions combining structure of motor, and the rear positions function that is positioned at shell has been a power supply function.The general blackboard eraser dust of solution of so just having realized dust absorption blackboard eraser of the present utility model is too many, the purpose of the technical problem of contaminated environment.
The beneficial effect of the dust absorption blackboard eraser of utility model is that the utility model is that the general blackboard eraser dust of solution is too many, big group of the technical scheme that technical problem adopted of contaminated environment and the existing and cleaning device about blackboard or slabstone that once had have the technology of the group of sucking chalk powder device to compare advantage and improvement everywhere:
The first, owing to designed motor in the technical scheme of dust absorption blackboard eraser of the present utility model, so easier solution provides the technical problem of power.
The second, owing to designed cloth bag in the technical scheme of dust absorption blackboard eraser of the present utility model, the technical problem that dust is regularly removed is collected in easier solution.
The 3rd, owing to designed the wind wheel screw in the technical scheme of dust absorption blackboard eraser of the present utility model, so the technical problem of easier solution dust suction.
The 4th, owing to designed battery in the technical scheme of dust absorption blackboard eraser of the present utility model, so the technical problem of easier solution power supply.
(4) description of drawings:
Accompanying drawing provides the structural representation of dust absorption blackboard eraser of the present utility model:
Fig. 1: the overall structure schematic diagram that is dust absorption blackboard eraser of the present utility model:
The label declaration of parts in the schematic diagram:
1 felt, 2 shells, 3 wind wheels, 4 motors, 5 batteries, 6 cloth bags
(5) specific embodiment:
Below in conjunction with accompanying drawing, too many for realizing solving general blackboard eraser dust to dust absorption blackboard eraser of the present utility model, the optimal way of the technical scheme that the technical problem of contaminated environment is taked is described further:
Its static structure: please join accompanying drawing: as shown in the figure, dust absorption blackboard eraser of the present utility model mainly is made of felt 1, shell 2, wind wheel 3, motor 4, battery 5, cloth bag 6.Its wind wheel 3, motor 4, battery 5 are by selecting for use on the market.Its felt 1 is a rectangular shape, uses batt material, through the braiding processing and manufacturing.Its shell 2 is rectangular shapes, uses the steel material, through rolling processing and manufacturing.Its cloth bag 6 is ball shapes, uses cloth material, through the braiding processing and manufacturing.
In shape, textural, the total essential features of dust absorption blackboard eraser of the present utility model and immediate prior art is: the felt 1 bonding forward position that is installed in shell 2, constitute the rectangular shape combining structure, and function has been the effect of erasing the board.In shape, textural, the dust absorption blackboard eraser of the present utility model technical characterictic different with immediate prior art is: motor 4 screws are fixedly mounted on the interior location of shell 2, constitute
Combination of shapes structure, function have been that dynamic action is provided.The cloth bag 6 bonding lower right end positions that are installed in shell 2 constitute " " combination of shapes structure, and function has been to collect the effect that airborne dust is regularly removed.Wind wheel 3 screw attachment are installed in the forward position of motor 4, constitute " H " combination of shapes structure, and function has been the dust suction effect.Battery 5 electric wire connection methods are installed in the rear positions combining structure of motor 4, and the rear positions function that is positioned at shell 2 has been a power supply function.
Its dynamic structure: in the optimal way of implementing, in use, in the time of when erasing the board, connect battery 5.According to electrical principles, its battery 5 acts on motor 4 by lead, thereby finishes the task of starting motor.According to principle of dynamics, its motor 4 acts on dust by wind wheel 3, makes it dust and is drawn onto enclosure interior wind wheel 3 behind, and dust leans on gravitational settling in cloth bag 6, thereby finishes the task of dust suction.The general blackboard eraser dust of solution tradition of so just having realized dust absorption blackboard eraser of the present utility model is too many, the technical problem purpose of contaminated environment.
Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of blackboard eraser and small machine factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of dust absorption blackboard eraser of the present utility model better with the demand of supply educational circles.
