Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
embodiment 1
As depicted in figs. 1 and 2, a kind of clean blackboard eraser, it comprises base plate 1 and sponge rub body 2, base plate 1 and sponge rub body 2 is utilized to form the main body of blackboard eraser, this base plate 1 and sponge rub body 2 adopt present technology to make and can be used in erasing the board, and wherein said sponge rub body 2 adopts fine and close sponge to form to have certain degree of hardness and meet the requirement erased the board.Offer a dust suction groove 3 bottom base plate 1 described in the present embodiment, described dust suction groove 3, along horizontally set outside described sponge rub body 2, adopts groove structure not affect and erases the board; The both sides cell wall 31 of described dust suction groove 3 is fixed with battery lead plate 4 respectively, described base plate 1 is provided with battery case, is provided with battery 5 in described battery case, the both positive and negative polarity of described battery 5 connects described battery lead plate 4 respectively by wire 51; This clean blackboard eraser is compared traditional blackboard and is wiped increase battery lead plate 4, battery 5 etc., a simple and easy capacitor is formed with this, when described battery 5 is communicated with described battery lead plate 4, described dust suction groove 3 is due to charge movement, absorption chalk dust, effectively can absorb chalk dust when erasing the board, reducing air pollution.Described base plate 1 inside offers water storage cavity, the corresponding described sponge rub body 2 of described water storage cavity offers permeability hole, on described base plate 1, corresponding described water storage cavity offers retaining mouth, utilize the characteristic that sponge rub body 2 absorbs water, make water-filling in sponge rub body 2, sponge rub body 2 water-filling during black plug plate, utilizes the suction-operated of water effectively to reduce chalk dust, coordinates the suction-operated of battery lead plate to reduce the pollution of chalk dust further simultaneously.
Described sponge rub body 2 is made up of three pieces of sponge blocks, the outer end that the outer end of sponge block 21 described in both sides exceeds middle described sponge block 22 is arranged, the outer end of three pieces of described sponge blocks forms the grey groove of storage, in order to ensure the assimilation effect of cavernous body 2 pairs of chalk dusts, described permeability hole respectively sponge block 21 described in corresponding both sides is arranged, during sassafras blackboard, utilize the sponge block 21 erasing chalk word of both sides humidity, the chalk dust produced is adsorbed with water, and the chalk dust simultaneously flown out enters the grey groove of storage or dust suction groove 3.
In order to ensure the normal work of capacitor, described battery lead plate 4 arrange in opposite directions be separately fixed at described dust suction groove 3 both sides cell wall 31 on, with this, chalk dust is absorbed.
For the ease of using, described wire 51 is provided with switch, and described switch is arranged on the top of described base plate 1.
