Description
Technical field:
The utility model relates to a kind of teaching aid, particularly relates to a kind of energy saving and environment friendly blackboard eraser.
Background technology:
Blackboard not refers in particular to the plate face of black, traditional sense is said it be one can the plane of repeated writing, plate face is hard, is used for teaching.Make with plank or ground glass etc., can to write above with chalk.Mostly be black, blackish green, white.Before word invention, it is found that charcoal can be drawn a picture, at some mural paintings that can find ancient times some ancient times in grotto in Europe, the crag drawing these mural paintings can be called blackboard from traditional sense.

The educational aid used both at home and abroad is at present still based on traditional blackboard chalk.For a long time, the teaching pattern that this blackboard adds chalk in use can produce a large amount of dust, and serious harm, to the physical and mental health of teachers and students, pollutes teaching environment, destroys teaching equipment.Although there is dustless clipboard on the market at present, there is many problems in it, as short in cost height service life etc., not easily promote the use of.Meanwhile, have also appeared now a kind of free ink pen writing whiteboard on the market, its structure is simple, mobile and easy to use, but the clipboard of blank is white, large to the eye irritation of student, is unfavorable for the protection for eyes.
Utility model content:
In order to solve the problem, the utility model provides one and effectively prevents dust from flying, and keep teaching environment health, brief introduction effectively improves the technical scheme in the service life of teaching equipment:
A kind of energy saving and environment friendly blackboard eraser, main body is blackboard eraser, comprises wiping board and snag, snag is connected with the front of wiping board, and wiping board inside is provided with inhales apparatus for ash and battery, inhales apparatus for ash and battery mutual conduction, inhale apparatus for ash and be connected with a starting switch, a dust-absorbing mouth and one deposit grey box.Starting switch is fixedly installed on any side of wiping board, and dust-absorbing mouth is arranged on wiping board front center position, deposits grey box and is fixedly installed on wiping board inside, and the wiping board reverse side depositing grey box and arrange relevant position is provided with removable cover.
As preferably, also comprise solar panel, solar panel is fixedly installed on wiping board reverse side removable cover with external position, solar panel and battery conducting.
As preferably, wiping board front edge is provided with sponge strip, and sponge strip height is lower than snag 5 ~ 15mm.
As preferably, on the removable cover on wiping board reverse side, optional position is fixedly installed transparent window.
The beneficial effects of the utility model are:
(1) wiping board inside of the present utility model is provided with and inhales apparatus for ash and battery, can open suction apparatus for ash when blackboard eraser uses simultaneously, reaches the effect reducing dust, thus realizes the object maintaining teaching environment health.
(2) also comprise solar panel in utility model, solar panel and battery conducting, directly produce electric energy by solar panel, reaches supply of electric power demand, realizes the effect of energy-conserving and environment-protective.
(3) blackboard eraser front edge is provided with sponge strip, effectively prevent blackboard eraser in use dust do not have enough time to be inhaled apparatus for ash and absorb and just overflow from blackboard eraser edge, reduce dust further.
(4) on the removable cover on wiping board reverse side, optional position is fixedly installed transparent window and can observes that the state of grey box is deposited in inside timely, clears up in time when depositing when in grey box, dust is more.
Accompanying drawing illustrates:
Fig. 1 is the utility model blackboard eraser Facad structure schematic diagram;
Fig. 2 is the utility model blackboard eraser inverse layer structure schematic diagram.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As Fig. 1, shown in Fig. 2, a kind of energy saving and environment friendly blackboard eraser, main body is blackboard eraser 1, and comprise wiping board 2 and snag 3, snag 2 is connected with the front of wiping board 3, wiping board 3 inside is provided with inhales apparatus for ash 4 and battery 5, inhale apparatus for ash 4 and battery 5 mutual conduction, inhale apparatus for ash 4 be connected with a starting switch 6, dust-absorbing mouth 7 and one deposit grey box 8.Starting switch 6 is fixedly installed on wiping board 3 arbitrarily side, and dust-absorbing mouth 7 is arranged on wiping board 3 front center position, and depositing grey box 8, to be fixedly installed on wiping board 3 inner, and wiping board 3 reverse side depositing grey box 8 and arrange relevant position is provided with removable cover 9.Can open when blackboard eraser 1 uses simultaneously and inhale apparatus for ash 4, reach the effect reducing dust, thus realize the object maintaining teaching environment health.
