Accompanying drawing explanation
Fig. 1 is the structural representation of the invention;
Fig. 2 is the structural representation of wiping shell in the invention;
Fig. 3 is the structural representation of screen pack in the invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
A dustproof blackboard eraser, comprises rub body 1, wipes shell 2, handle 3, screen pack 4, dust exhaust apparatus 5 and dust suction button 6; Described wiping shell 2 is that one end is the box body shape structure of opening; Described handle 3 is connected to be wiped on shell 2, and the inner dust absorption passage arranging of handle 3 is communicated with wiping shell 2 inner chambers; Described dust exhaust apparatus 5 and dust suction button 6 are all arranged on handle 3; Described wiping shell 2 openends are provided with connecting plate 7; Described rub body 1 is connected to a side that differs from wiping shell 2 on connecting plate 7; Described screen pack 4 is propped up by rub body 1, and its main part is placed in wipes shell 2 inner chambers; On described rub body 1, there are some air suction openings.
Described rub body 1 comprises the wiping layer 12 arranging on wiping board 11 and wiping board 11.Wiping layer 12 can be the hairbrush of nylon, can be also layer of cloth with holes.On wiping board 11, have some through holes as air suction opening, dust can be adsorbed to screen pack 4 from these air suction openings.
Described screen pack 4 comprises joint portion 41, connecting portion 42 and compressed part 43; Described joint portion 41 is placed in wipes shell 2 inner chambers, and connecting portion 42 is connected with connecting plate 7, and compressed part 43 is propped up by rub body 1.
The compressed part 43 of described screen pack 4 is provided with chamfering 431.This chamfering 431, as the mark of screen pack 4 anti-reverse mountings, is dismantled screen pack 4 at every turn, only the side with chamfering need be propped up by wiping board 11, can not affect because of anti-loaded screen pack 4 effect of dust suction.
Described connecting portion 42 is provided with locating hole.Described connecting plate 7 is provided with buckle 71, and its side surface towards rub body 1 is provided with several locating dowels 72.
When screen pack 4 is installed, the locating hole that only locating dowel 72 need be injected on screen pack 4 connecting portions 42, is then stuck in wiping board 11 buttons on the buckle 71 of connecting plate 7 projections.Convenient and swift, there will not be assembling gap.
