Description
(1) technical field:
The utility model relates to dust-free black board 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, and 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-free black board eraser was all done very fruitful effort, also once designed many outstanding technical schemes about blackboard or slabstone.Declare as being kindly helped secure the success of by car of the Decree of Patent Office of China in 1996, Granted publication number is CN2219799Y, and China Patent No. (ZL) is: No. 95230044.3 utility model title is the utility model patent of " dust absorption 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 problem of dust absorption blackboard eraser effectively.But still have some deficits, it also is difficult to the very big problem of blackboard ash when erasing the board that solves.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of dust-free black board eraser.The very big problem of blackboard ash when erasing the board with solution.
The purpose of this utility model is achieved in that the dust-free black board eraser of this utility model.Mainly wipe and constitute by stopper, plate body, button, rubber, spring, hair.Its rubber, spring, hair are wiped by selecting for use on the market.Its stopper is a cylindrical shape, uses elastomeric material, through the injection moulding processing and manufacturing.Its plate body is the prolate square configuration, uses plastic material, through moulding processing and manufacturing.Its button is a cylindrical shape, uses plastic material, through moulding processing and manufacturing.Stopper adopts direct blocking method to be installed in the position, the upper right corner of plate body, constitutes small embossment shape removable structure, and function has been to prevent to leak effect.Button adopts adhering method to be connected the apical position of rubber, constitutes small embossment elasticity of shape structure, and function is to start to control the water effect of making.Rubber adopts adhering method to be connected the apical position of spring, constitutes the block-shaped elastic construction of piece, and function is to start to control the water effect of making.Spring adopts adhering method to be connected the inner bottom part position of plate body, constitutes spring elasticity of shape structure, and function has been a reduction.Hair is wiped and is adopted adhering method to be connected the inner bottom part position of plate body, constitutes hairbrush fixed in shape structure, and function has been the wiping water sorption.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 has designed water injection system in technical scheme, so dustless after having wiped;
The second, because the utility model has designed the thin hairbrush in preceding thick back in technical scheme, so the wiping back is anhydrous; Thereby just can more effectively solve the very big problem of blackboard ash when erasing the board.
(4) description of drawings:
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall structure schematic diagram of dust-free black board eraser of the present utility model;
The numbering of parts explanation in the schematic diagram: 6 maos of wipings of 1 stopper 2 plate bodies, 3 button 4 rubber, 5 springs
(5) specific embodiment:
In the optimum implementation of dust-free black board 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: see also Fig. 1: as shown in the figure, dust-free black board eraser of the present utility model.Mainly wiping 6 by stopper 1, plate body 2, button 3, rubber 4, spring 5, hair constitutes.Stopper 1 adopts direct blocking method to be installed in the position, the upper right corner of plate body 2, constitutes small embossment shape removable structure, and function has been to prevent to leak effect.Button 3 adopts adhering method to be connected the apical position of rubber 4, constitutes small embossment elasticity of shape structure, and function is to start to control the water effect of making.Rubber 4 adopts adhering method to be connected the apical position of spring 5, constitutes the block-shaped elastic construction of piece, and function is to start to control the water effect of making.Spring 5 adopts adhering method to be connected the inner bottom part position of plate body 2, constitutes spring elasticity of shape structure, and function has been a reduction.Hair is wiped 6 and is adopted adhering method to be connected the inner bottom part position of plate body 2, constitutes hairbrush fixed in shape structure, and function has been the wiping water sorption.
Its dynamic structure: in force:
According to elastic principle, its button 3 acts on water by rubber 4, thereby finishes the task of water outlet.So just realized the purpose of this utility model.Thereby just can solve the very big problem of blackboard ash when erasing the board.
Below by using method, the utility model is done more detailed description:
The dust-free black board eraser of this utility model is work like this:
In use, when using, palm is placed on the plate body 2, and button 3 is touched.According to elastic principle, its button 3 acts on water by rubber 4, thereby finishes the task of water outlet.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of blackboard eraser factory, take large quantities of producing by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
