Description
Technical field
The utility model relates to teaching aid field, especially a kind of energy saving and environment friendly blackboard eraser.
Background technology
At present, existing blackboard eraser wipes after blackboard, can cause dust to descend slowly and lightly everywhere, not only pollute indoor environment, also had a strong impact on the healthy of academics and students, the disadvantage that existing blackboard eraser exists is that after wiping blackboard, dust directly descends slowly and lightly, and there is no dust take-up means, and this gives and often uses the school of blackboard eraser to bring very large puzzlement.People had invented a kind of Environmental protecion eraser afterwards, comprise by top board, base plate, header board, the blackboard eraser body of rear plate and two side plate compositions, on header board, be provided with the felt for blackboard wiping face, in the middle of rear plate, be provided with the solar panel for energy is provided, the magnetic stripe for dust adsorption is equipped with in the both sides of solar panel, a side plate on blackboard eraser body is provided with dust import, dust import one side arranges tactile switch, base plate is provided with dust outlet, the upper drawing and pulling type switch that connects of dust outlet, the Environmental protecion eraser of this structure, complex structure, cost is high, be unfavorable for promoting.Existing a kind of blackboard eraser with Dust-proof bag, because Dust-proof bag is to be made up of air-locked soft cloth material, so soft cloth material can exist the problem that porch is blocked naturally along with himself weight tenesmus, is inconvenient to use.
Summary of the invention
The purpose of this utility model is to provide a kind of energy saving and environment friendly blackboard eraser, can solve the problem of the high and inconvenient use of current eraser structure complexity, cost.
Technical scheme provided by the utility model is: a kind of energy saving and environment friendly blackboard eraser, comprise base plate, base plate is provided with nearly wind hole, above described nearly wind hole, be provided with the blower fan for inhaling dust, above blower fan, be provided with dust cover, the side of dust cover is provided with the Dust-proof bag for collecting dust, and the lengthwise edge of described Dust-proof bag is fixedly connected with aluminium wire.
Further, described dust cover is provided with the power supply of fan power supply and the switch for cutting off the electricity supply, and switch, power supply and blower fan are connected by wire.
Further, on described base plate for the felt of blackboard wiping.
Further, the surrounding of described base plate is provided with the baffle plate that prevents that dust from disorderly flying.
The beneficial effects of the utility model are:
The utility model is fixedly connected with aluminium wire in the lengthwise edge of Dust-proof bag, aluminium wire has enough large hardness and toughness, therefore the shape of utilizing the hardness of aluminium wire can fix Dust-proof bag is not plugged dust inlet place, in the time no longer needing to use cloth bag to collect dust, can utilize the toughness of aluminium wire that porch is blocked, simple in structure, design ingenious, easy to use, in addition, the utility model adopts blower fan to inhale dust, and cost is low like this, dust can be changed Dust-proof bag after having expired, and uses so more convenient.
