Description
Technical field
The present invention relates to a kind of teaching aid, particularly relate to a kind of blackboard eraser for environmental protection.
Background technology
The educational aid used the most both at home and abroad is still based on traditional blackboard chalk.For a long time, this blackboard adds the teaching model of chalk in use can produce substantial amounts of dust, the physical and mental health of serious harm to teachers and students, pollutes teaching environment, destroys teaching equipment.Blackboard eraser on known market and inside school is essentially all traditional plastic blackboard and wipes, and this blackboard eraser is made up of together with felt bonding plank.Although this kind of blackboard eraser is light, convenient use, but there is distinct disadvantage
: substantial amounts of chalk dust, the health of harm teachers and students can be produced during by felt contacts blackboard panel reciprocating friction, make academics and students be drawn onto a large amount of powder and cause respiratory system disease；The chalk dust produced flies away everywhere, not only contaminated air but also waste resource.Recent development goes out a dust absorption blackboard eraser on the market, the principle of its vacuum cleaner used, and the dust that will produce when erasing the board sucks blackboard eraser intracavity, but it has and also has open defect
: the first power consumption is big, and owing to using vacuum cleaner principle, though it is huge to cause reaching pick-up performance power consumption, second, volume is big, and noise is big, owing to its dust is to be directly sucked in the cavity of blackboard eraser, so bulky；The noise that during dust suction, fan produces is very big, and the study of teachers and students on classroom can be hindered to imitate.
Summary of the invention
For the problem solving to propose in above-mentioned background technology, it is an object of the invention to provide a kind of blackboard eraser for environmental protection, this blackboard eraser can not only wipe the word on blackboard quickly, and can substantial amounts of powder be collected in powder box, overcome the dust that existing product produces due to felt contacts blackboard space of a whole page reciprocating friction, effectively prevent dust from flying, keep teaching environment health, reduce the dust harm to teachers and students' health.
For achieving the above object, technical scheme is as follows:
A kind of blackboard eraser for environmental protection, including blackboard eraser body, blackboard eraser body is provided with wiping board, it is provided with snag in the front of wiping board, it is characterized in that: have suction apparatus for ash, circuit board and accumulator blackboard eraser body is internally installed, inhaling apparatus for ash to be connected with circuit board by wire, the side in blackboard eraser body is provided with activate switch, electricity display lamp and the charge port being all connected with circuit board, and circuit board is connected with storage battery by wire；Inhale apparatus for ash side be provided with deposit ash box, and deposit ash box be fixed on inside blackboard eraser body；Wiping board is provided with dust-absorbing mouth, and dust-absorbing mouth is communicated with depositing ash box by suction apparatus for ash.
Further, outside described snag, it is provided with solar panel, and solar panel is connected with accumulator by wire.It is provided with sponge strip outside described solar panel.Snag and sponge strip, can carry out dismounting and change.
The described ash box back side of depositing is provided with removable cover, and removable cover arranges transparent windows.Dust-absorbing mouth is arranged on wiping board front center position.Described suction apparatus for ash be fan or other can make dust suck deposit ash box in facility, it is also possible to be the electrostatic ball with adsorption function.
Described charge port includes that power source charges mouth and USB charge port, activate switch and electricity display lamp are arranged on the same flank side surface of blackboard eraser body, power source charges mouth and USB charge port and are separately positioned on two flank side surface of blackboard eraser body.
Compared with prior art, the Advantageous Effects of the present invention is embodied in following aspect: first, and electricity display lamp of the present invention is arranged at the flank side surface of body, when blackboard eraser electricity deficiency, can find in time, it is to avoid suction apparatus for ash when causing blackboard eraser to use, cannot be started.It is provided with suction apparatus for ash and accumulator inside wiping board, suction apparatus for ash can be opened when blackboard eraser uses simultaneously, reach to reduce the effect of dust, thus realize maintaining the purpose of teaching environment health.Secondly also including solar panel in the present invention, solar panel arranges snag outer fix, and solar panel turns on accumulator, directly produces electric energy by solar panel, reaches supply of electric power demand, it is achieved the effect of energy-conserving and environment-protective.Finally wipe sun and can be provided with sponge strip outside cell panel, effectively prevent blackboard eraser in use dust from having not enough time to be inhaled apparatus for ash absorption and just overflow from blackboard eraser edge, reduce dust further.Depositing the ash box back side and be provided with removable cover, removable cover is arranged above transparent windows, can observe that the state of ash box is deposited in inside timely, clears up in time time more when depositing dust in ash box.
The present invention is reasonable in design, simple in construction, easy to use, energy-conserving and environment-protective, it is adaptable to the wiping of letter written with chalk and the collection of chalk dust.
