Description
Technical field
The present invention relates to a kind of anti-airborne dust blackboard eraser, more particularly to a kind of anti-airborne dust blackboard eraser of portable.
Background technology
All the time, this occupation is erased the board by everybody worry, and the white bits that fluttering is danced in the air can airily descend slowly and lightly
Onto your hair, on clothes, it is not that complaints are heard everywhere to be sitting in following classmates, is exactly low especially on pitiful sleeve ...
Head has sealed nose, runs into and ill-matched can also be thrown out --- but blackboard has to wipe.
Convenient blackboard is wiped, big the purpose is to solve dust when blackboard eraser erases the board；First wiped one time with blackboard eraser, then smeared with wet
Cloth wipe a hell to pay technical problem, it mainly by blackboard wiping board, sponge wiping board, Small-sized suction cleaner, button switch, brush,
Wet sponge, column are formed.It is characterized in that：The lower position of blackboard wiping board is installed on the position of the upside of Small-sized suction cleaner with screw
Put, installed in the position of the bottom surface of blackboard wiping board, the upper position of wet sponge is nested to be installed on sea for the apical position bonding of brush
The position of the inside of continuous wiping board, the two side positions bonding of crossbeam handle is installed in the position on the top of column, the overall position of magnet
The position of the nested middle inside for being installed on crossbeam handle is put, is led suitable for cleaning of the practical new technical solution in blackboard or slabstone
In domain.
Trendy electric blackboard eraser be it is a kind of integrate wipe word, the novel environment friendly teaching aid of electric dust absorption, its Beauty
Compact, good dedusting effect is seen, deep to be liked by numerous teachers and students, which can thoroughly eliminate dust, improve the teaching environment in classroom,
Avoid for a long time teacher suffer from sphagitis, pulmonary tuberculosis disease because of " eating chalk dust ".
The content of the invention
For the above situation, to overcome the defect of the prior art, the purpose of the present invention is just to provide a kind of portable and prevents raising
Dirt blackboard eraser, it is therefore intended that solve traditional blackboard wipe can not dust-proof and effective dust, and general blackboard eraser dust-proof effect is poor
The problem of.
Its technical solution is, including blackboard eraser body, dust collecting box, reverse V-shaped metal screen, extraction fan, metal are prevented
Protecting wire net, shield dirt bar, blackboard eraser bottom plate and felt block, be installed with the anti-airborne dust blackboard eraser body of portable dust collecting box,
Reverse V-shaped metal screen, extraction fan, chain link fence, shield dirt bar, blackboard eraser bottom plate and felt block, blackboard eraser body rear end are consolidated
Surely dust collecting box is equipped with, reverse V-shaped metal screen is fixed with dust collecting box, is fixed among reverse V-shaped metal screen
Extraction fan, chain link fence are fixedly connected with blackboard eraser bottom plate, and felt block is fixed with blackboard eraser bottom plate.
The blackboard eraser body is specifically made of polypropylene plastics, and shape is a kind of cylinder combining structure, and front end is justified
Column diameter 6cm, a diameter of 3cm of back end cylindrical body, the dust collecting box are internally provided with strong viscous paste, and paste thickness is
0.8cm, paste are internally provided with adsorption hole, and effective aperture is no more than 2mm.
The reverse V-shaped metal screen and chain link fence is made by Q235 stainless steels, and reverse V-shaped metal screen V-type is opened
Mouth length is 2mm, and the number of plies is 2 layers, and is interlocked layer by layer, and chain link fence is specially the metal aperture that a kind of pass is prismatic.
The extraction fan is a kind of rotating electric fan of microphyll, the trans installation of blade, operating voltage 12V, work(
Rate consumption is no more than 10W.
The shield dirt bar is specially a circular ring type structure, shorter 2-4mm than felt block, is soft, flexible cavernous body
Material, thickness are not less than 2mm.
The blackboard eraser bottom plate is embedded in inside blackboard eraser body, and structure is circular, thickness 2cm, the felt block
For a kind of synthetic fibers, the thickness of felt block is no more than 4cm.
The anti-airborne dust blackboard eraser low cost of this practical convenient formula, simple in structure, novel in design, easy to use, the present invention is internal
Extract system is set, can effectively prevent chalk dust airborne dust, harm of the chalk dust to human body and environment is reduced, solves traditional blackboard
Wipe can not dust-proof and effective dust, and the problem of general blackboard eraser dust-proof effect is poor.
