Description of drawings
Fig. 1 is the utility model structural representation.
1 is that power switch 2 is shell for battery 7 for base plate with holes 8 for hairbrush 6 for micro-cleaner 5 for flashboard 4 for handle 3 among the figure
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, this electrical dust-removing blackboard eraser comprises handle 2, power switch 1, battery 6, shell 8, micro-cleaner 4, flashboard 3 and hairbrush 5.Described handle 2 is bonded together with shell 8; Described power switch 1 is arranged on handle 2 one sides; Described shell 8 one sides have groove and have base plate with holes 7; Described flashboard 3 places shell 8 grooves; Described hairbrush 5 and shell 8 base plate stickings with holes are connected; Described battery 6 and micro-cleaner 4 place in the shell 8; Be connected with lead between described battery 6 and power switch 1 and the micro-cleaner 4.
When erasing the board, grasp handle 2, and press the power switch 1 of lower handle 2 one sides, micro-cleaner 4 startups were close to blackboard with hairbrush 5 and were carried out wiping this moment.Chalk dust can be absorbed shell 8 inside by the micro-cleaners 4 in the shell 8, can not cause that chalk dust is floating to be sucked by human body everywhere, because handle 2 has with a certain distance from blackboard, hand can not touch the chalk dust on the blackboard yet.Behind the intact blackboard of wiping, press power switch 1 once more, micro-cleaner 4 quits work.When the chalk dust of shell 8 inside runs up to some, can open flashboard 3 and pour out chalk dust, convenient and swift.Battery in the utility model adopts rechargeable battery.
