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-sucking blackboard eraser of spraying water as described in Fig. 1-Fig. 3, comprise insulation box body 8 and water jet, 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 comprises water storage cylinder 25, and the two ends of water storage cylinder 25 are respectively arranged with atomizer 24 and water outlet button 26, and described water storage cylinder 25 periphery is also provided with buckle 27, 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 is coordinated with draw-in groove by buckle 27 and dismountable being connected to is insulated on box body 8.
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 26 can be extruded, thus the water in water storage cylinder 25 or cleaning agent are sprayed on blackboard by atomizer 24, re-use blackboard hairbrush 1 wiping, can very easily by writing wiped clean, and act on due to atomizer 24, the water of each ejection is atomization, amount is few, thus can ensure that blackboard can not drench after wiping, conveniently use immediately, and water jet is clamped by draw-in groove, thus for convenience detach, all very convenient when needs again fill water or take off.
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.
