It is connected on plastic plate 5, the edge of the aluminium foil 2 and plastic plate 5 is bonded in insulation box body 8 by the adhesive sheet 3 that insulate and opened
Mutually isolated upper chamber and lower chambers are separated to form by isolating transverse slat 10 inside the inner side at mouthful end, the installation cavity, it is described
Upper chamber is internally provided with the tourmaline 9 that is provided with and can be slided in fixed bin 7 in fixed bin 7, fixed bin 7, and tourmaline 9 passes through
Wire is connected and is provided with vertical clapboard 17 in the middle part of plastic plate 5, the bottom chamber, and lower chambers are separated to form by vertical clapboard 17
The laying dust chamber 21 and isolation chamber 14 of connection are held, the upper end of vertical clapboard 17 is provided with screen pack 16, the isolation chamber
Dust absorption fan 11 is just provided with 14 to screen pack 16, dust absorption fan 11 is connected with battery 18, the insulation booth by motor 13
Body 8 is located at isolation chamber 14 bottom and is provided with air outlet 19, and the outside of insulation box body 8 is provided with opening for the control break-make of battery 18
Button 15 is closed, the insulation box body 8 is additionally provided with removable end cap 20 positioned at the bottom of laying dust chamber 21；The aluminium foil 2 and plastics
Be additionally provided with plate 5 connected with laying dust chamber 21 enter dirt hole 22；The water jet 25 includes water storage cylinder 252, water storage cylinder 252
Two ends are respectively arranged with atomizer 251 and water outlet button 253, and the periphery of water storage cylinder 252 is additionally provided with buckle 254；Institute
State and the fixture block 23 with neck is provided with the outside of insulation box body 8 upper surface, the water jet 25 is coordinated by buckle 254 and neck
And be removably attachable on insulation box body 8；The laying dust box 24 includes laying dust box body 242, and the inner upper end of laying dust box body 242 is set
It is equipped with the minicell 243 and mini-fan that interconnection is additionally provided with inside positioning step 248, the laying dust box body 242
245, the outer end of mini-fan 245 is cased with filtering screen 246, and the bottom of laying dust box body 242 is located at the position of mini-fan 245
Install and be equipped with air vent 244, the bottom of the laying dust box body 242 is provided with arc lower margin 241, the side of the laying dust box body 242
Face is provided with the controlling switch 247 that control mini-fan 245 is switched, and the laying dust box 24 and arc lower margin 241 are conduction material
Material is made；The insulation box body 8 be can be placed in laying dust box 24, and aluminium foil 2 is contacted with positioning step 248.
In the present embodiment, aluminium foil 2, plastic plate 5 and tourmaline 9 are collectively forming the electrostatic transmitter of a suggestion, work as blackboard
Wipe when in use, tourmaline 9 is in the random motion of fixed bin 7, so that friction is contacted with fixed bin 7, due to the electrostatic of tourmaline 9
Characteristic, the surface of tourmaline 9 produces electrostatic, is passed to by wire on plastic plate 5, now because aluminium foil 2 and plastic plate 5 insulate,
Electrostatic produces charge inducing on aluminium foil 2, so as to produce electrostatic, and chalk dust is adsorbed in aluminium foil under electrostatic interaction again after being erased
On 2, because tourmaline 9 persistently provides electrostatic, therefore dust suction can be continued in erase process, good pick-up performance is played,
Reduce the pollution of dust, it is ensured that the health of teachers and students, beautify teaching environment.
When the writing on blackboard is difficult to wipe, water outlet button 253 can be extruded, thus by the water in water storage cylinder 252 or
Cleaning agent is sprayed on blackboard by atomizer 251, reuses blackboard hairbrush 1 and wipes, you can very easily by writing wiped clean,
And because atomizer 251 is acted on, the water sprayed every time is atomization, amount is few, thereby may be ensured that blackboard is not after wiping
It can drench, it is convenient to use immediately, and water jet coordinates clamping by buckle 254 and neck, so that convenient dismounting, is needing again
It is very convenient when filling water or removing.
After blackboard eraser use, insulation box body 8 can be lain against in laying dust box 24, now aluminium foil 2 connects with positioning step 248
Touch, the electrostatic of aluminium foil 2 is eliminated after being connected by laying dust box body 242 and arc lower margin 241 with desk, while passing through controlling switch
247 connect minicell 243 and mini-fan 245, open mini-fan 245, so as to adsorb in blackboard hairbrush 1 and aluminium
Chalk dust on paper tinsel 2, the chalk dust on the two is adsorbed in laying dust box body 242, it is to avoid the dust four when picking and placeing insulation box body 8
Place disorderly flies, while blackboard hairbrush 1 and aluminium foil 2 can also be cleaned, improves wiping and the adsorption effect of the two, can use and nothing for a long time
Blackboard hairbrush 1 need to be cleaned.
Installation cavity is separated into upper chamber and lower chambers by the present embodiment, and tourmaline 9 is arranged in upper chamber and separated, it is to avoid
Influence of the dust to tourmaline；When Electrostatic Absorption is in some wet weathers or rainy weather less effective, dust suction can be passed through
Dust is sucked lower chambers by fan 11, and is filtered by screen pack 16, and the dust of filtering is then deposited in laying dust chamber 21, works as product
In dirt chamber 21 after a certain amount of dust of accumulation, removable end cap 20 can be opened and pour out dust.
In the present embodiment, solid gum 4 can not only connect aluminium foil 2 and plastic plate 5, while the two can also be isolated, and shape
Into similar capacitance structure, so that aluminium foil 2 can more produce charge inducing, electrostatic is produced；Insulation adhesive sheet 3 can prevent aluminium foil
2 and plastic plate 5 with insulation box body 8 contact, so as to avoid contacting with the external world so that electrostatic be lost in, insulation box body 8 insulation be also for
The electrostatic is avoided to be lost in.
