Detailed description of the invention
In order to make those skilled in the art understand the present invention better, below in conjunction with the embodiment of the present invention and accompanying drawing, clear, complete explanation is carried out to technical scheme of the present invention.
Embodiment 1
A kind of dust suction as described in Fig. 1-Fig. 4 and the effective blackboard eraser of laying dust, comprise insulation box body 8, water jet 25 and laying dust box 24, insulation box body 8 is the hollow rectangle structure of an opening, the inside of hollow rectangle structure is installation cavity, the openend of installation cavity is disposed with insulated brush 1 from outside to inside, aluminium foil 2 and plastic plate 5, described aluminium foil 2 is bonded on plastic plate 5 by solid gum 4, the edge of described aluminium foil 2 and plastic plate 5 is all bonded in the inner side of insulation box body 8 openend by insulating sticky fishplate bar 3, described installation cavity inside is separated to form mutually isolated upper chamber and lower chambers by isolation transverse slat 10, described upper chamber inside is provided with fixed bin 7, the tourmaline 9 that can slide in fixed bin 7 is provided with in fixed bin 7, tourmaline 9 is by wire connection plastic flitch 5, vertical clapboard 17 is provided with in the middle part of described bottom chamber, lower chambers is separated to form laying dust chamber 21 and the isolated chamber 14 of upper end connection by vertical clapboard 17, described vertical clapboard 17 upper end is provided with screen pack 16, just dust absorption fan 11 is provided with to screen pack 16 in described isolated chamber 14, dust absorption fan 11 is connected with battery 18 by motor 13, described insulation box body 8 is positioned at bottom isolated chamber 14 and is provided with air outlet 19, described insulation box body 8 arranged outside has the shift knob 15 controlling battery 18 break-make, described insulation box body 8 is positioned at bottom laying dust chamber 21 and is also provided with removable end cap 20, described aluminium foil 2 with plastic plate 5 is also provided be communicated with laying dust chamber 21 enter dirt hole 22, described water jet 25 comprises water storage cylinder 252, and the two ends of water storage cylinder 252 are respectively arranged with atomizer 251 and water outlet button 253, and described water storage cylinder 252 periphery is also provided with buckle 254, the arranged outside of described insulation box body 8 upper surface has the fixture block 23 of band draw-in groove, and described water jet 25 is coordinated with draw-in groove by buckle 254 and dismountable being connected to is insulated on box body 8, described laying dust box 24 comprises laying dust box body 242, laying dust box body 242 inner upper end is provided with positioning step 248, described laying dust box body 242 inside is also provided with interconnective minicell 243 and mini-fan 245, described mini-fan 245 outer end cover has filtering screen 246, the position being positioned at mini-fan 245 bottom described laying dust box body 242 is provided with air vent 244, the bottom of described laying dust box body 242 is provided with arc lower margin 241, the side of described laying dust box body 242 is provided with the gauge tap 247 controlling mini-fan 245 switch, described laying dust box 24 and arc lower margin 241 are conductive material and make, described insulation box body 8 can be placed in laying dust box 24, and aluminium foil 2 contacts with positioning step 248.
In the present embodiment, aluminium foil 2, plastic plate 5 and tourmaline 9 form the electrostatic transmitter of a suggestion jointly, when blackboard eraser in use, tourmaline 9 is in fixed bin 7 random motion, thus with fixed bin 7 contact friction, due to the static characteristic of tourmaline 9, tourmaline 9 surface produces electrostatic, pass on plastic plate 5 by wire, now because aluminium foil 2 and plastic plate 5 all insulate, electrostatic produces charge inducing on aluminium foil 2, thus generation electrostatic, chalk dust is adsorbed on aluminium foil 2 under electrostatic interaction after being erased again, because tourmaline 9 continues to provide electrostatic, therefore dust suction can be continued in erase process, play good pick-up performance, decrease the pollution of dust, ensure that the health of teachers and students, beautify teaching environment.
When the writing on blackboard is difficult to wiping, water outlet button 253 can be extruded, thus the water in water storage cylinder 252 or cleaning agent are sprayed on blackboard by atomizer 251, re-use blackboard hairbrush 1 wiping, can very easily by writing wiped clean, and act on due to atomizer 251, the water of each ejection is atomization, amount is few, thus can ensure that blackboard can not drench after wiping, convenient to use immediately, and water jet is coordinated with draw-in groove by buckle 254 and clamps, thus for convenience detach, all very convenient when needs again fill water or take off.
After blackboard eraser uses, can insulation box body 8 be lain against in laying dust box 24, now aluminium foil 2 contacts with positioning step 248, the electrostatic of aluminium foil 2 is communicated with rear eliminate with arc lower margin 241 with desk by laying dust box body 242, connect minicell 243 and mini-fan 245 by gauge tap 247 simultaneously, open mini-fan 245, thus the chalk dust that can will be adsorbed on blackboard hairbrush 1 and aluminium foil 2, chalk dust on the two is adsorbed in laying dust box body 242, the dust when picking and placeing insulation box body 8 is avoided disorderly to fly everywhere, blackboard hairbrush 1 and aluminium foil 2 can also be cleaned simultaneously, the wiping of both raisings and adsorption effect, can to use for a long time and without the need to cleaning blackboard hairbrush 1.
Installation cavity is separated into upper chamber and lower chambers by the present embodiment, is arranged in upper chamber by tourmaline 9 and separates, and avoids dust on the impact of tourmaline; When Electrostatic Absorption is at some wet weathers or rainy weather less effective, by dust absorption fan 11, dust is sucked lower chambers, and filtered by screen pack 16, the dust filtered then is deposited in laying dust chamber 21, after piling up a certain amount of dust in laying dust chamber 21, removable end cap 20 can be opened dust is poured out.
In the present embodiment, aluminium foil 2 can not only be connected with plastic plate 5 by solid gum 4, also the two can be isolated simultaneously, and form similar capacitance structure, thus make aluminium foil 2 more can produce charge inducing, produces electrostatic; Insulating sticky fishplate bar 3 can prevent aluminium foil 2 from contacting with insulation box body 8 with plastic plate 5, thus avoids and extraneous contact, and electrostatic is run off, and it is also in order to avoid electrostatic runs off that insulation box body 8 insulate.
Embodiment 2
The present embodiment adds following structure on the basis of embodiment 1: described insulation box body 8 side is also provided with the gauge tap 6 for being switched on or switched off wire 11.
The gauge tap 6 of the present embodiment can being switched on or switched off of pilot, thus can when not using blackboard eraser break line, avoid not using generation electrostatic, avoid the teachers and students hired roughneck because of electrostatic in use.
Embodiment 3
The present embodiment adds following structure on the basis of embodiment 1 or embodiment 2, is specially: the lateral surface that described insulation box body 8 is positioned at the other end of openend is also provided with handle 12.
The present embodiment conveniently uses and picks and places, and reduces human hands simultaneously and contacts with insulation box body 8, and the special lateral surface being positioned at the other end of openend at the box body 8 that insulate arranges handle 12, and teachers and students can hold handle 7 and carry out blackboard eraser and remove, very convenient.
Well can realize the present invention as mentioned above.Scope of patent protection of the present invention is as the criterion with claims, the equivalent structure change that every utilization description of the present invention and accompanying drawing content are done, and in like manner all should be included in protection scope of the present invention.
