Description
Technical field
The utility model is related to a kind of blackboard eraser, and in particular to a kind of dust-proof blackboard eraser.
Background technology
Blackboard eraser is one of essential instrument in classroom, and at present, conventional blackboard eraser is to set hairbrush system on plank
Make, the clothes cuff and palm of the user that easily made dirty during erasing the board, meanwhile, the chalk dust under wiping is danced in the air all over the sky, quilt
In teacher and front-seat classmate's suction inlet and in nose, the health of the respiratory system of numerous teachers and students is had a strong impact on.According to incompletely statistics,
The chalk of one primary school teacher's consumption daily is about 6, and the chalk that middle school teacher uses daily is more, what these chalks were produced
Chalk dust has a big chunk to enter inside of human body by breathing by teachers and students, the healthy of teachers and students is had a strong impact on, additionally, chalk
The grey overwhelming majority descends slowly and lightly on the ground, and the cleaning to student on duty for the day brings certain difficulty.So, the powder that reduction is produced when erasing the board
Pen ash and chalk ash collection gets up be uniformly processed is one of current urgent problem.
Chinese patent 201520805155.2 discloses blackboard eraser, including blackboard eraser body, storage tank, sparge pipe, water inlet
Mouth, button, magnet, expansion link, draw ring, window and wiper, solve current blackboard eraser and are difficult to effectively contain dust, and wiper is damaged
It is just unrenewable after bad, cause the problem of the wasting of resources；But flying for dust is prevented using water injector when the blackboard eraser is used
Dance, causes that blackboard surface is wetter can not to write, it is necessary to write after waiting blackboard to dry immediately after use, so cause classroom
Hours of instruction shorten, influence teacher piece-by piece teaching plan.
Utility model content
The purpose of this utility model is to provide a kind of dust-proof blackboard eraser, to solve to cause powder when traditional blackboard erases the board
Pen ash dances in the air the problem for having a strong impact on teachers and students' respiratory health all over the sky.
A kind of dust-proof blackboard eraser that the utility model is provided, including blackboard eraser box body, the blackboard eraser box body set electricity
Magnet, the electromagnet sets the first iron plate, and first iron plate connects the second iron plate, and second iron plate sets two pieces of sponges
Wipe, the blackboard eraser box body side sets water tank, the water tank connects the first sparge pipe by the first water pipe, and the water tank passes through
Second water pipe connects the second sparge pipe, and the blackboard eraser tray interior sets high-pressure mini air pump, and the high-pressure mini air pump connects
Air jet pipe is connect, the air jet pipe sets handle, the blackboard eraser box at least provided with a jet thrust, the blackboard eraser box body back
External side sets control device.
Further, the control device sets electro-magnet switch and high-pressure pump switch.
Further, first water pipe sets first switch.
Further, second water pipe sets second switch.
Further, first sparge pipe and the second sparge pipe are respectively provided with fountain head.
Further, the jet thrust number is 8~30, and the jet thrust is evenly distributed on air jet pipe.
The beneficial effects of the utility model are：（1）The dust-proof blackboard eraser that the utility model is provided, when using, setting
Two sparge pipes can effectively prevent the setting of dancing in the air for chalk dust, two sparge pipes from increased to blackboard surface sprinkling
The effect of letter written with chalk erasing, air jet system is more the increase at sparge pipe rear portion（High-pressure mini air pump, air jet pipe, jet thrust）,
Pressure-air can be blowed to wetter blackboard surface and timely dry up blackboard, effectively solve existing spraying eraser erasing
The wetter problem that can not be used immediately in blackboard surface is caused after font.
（2）The dust-proof blackboard eraser that the utility model is provided, the second iron plate for being provided with sponge brush can be by electricity
Magnet arrangement is very easily dismantled, and is rinsed after per class beneficial to sponge brush.
The utility model provide dust-proof blackboard eraser, the chalk dust produced when effectively can prevent from erasing the board and
Wetter blackboard is dried up immediately, facilitates the use in the middle of teachers and students classroom, be conducive to protect teachers and students it is healthy.
