The utility model is in order to solve the problems of the technologies described above by the following technical solutions:
The utility model provides a kind of multifunctional blackboard eraser, comprise and wipe box and be fixed on the cleaning part of wiping on the box, has a cavity in the described wiping box, at the wiping box dust exhaust apparatus is set, described dust exhaust apparatus comprises the dust catcher that is arranged on the switch of wiping the box side, the air suction opening that is communicated with described cavity, is arranged on charged in the described cavity, and described switch and dust catcher are connected in series.
As a kind of optimal technical scheme of the present utility model: the outer wall of described wiping box is provided with open cap, and this open cap is arranged on the position corresponding with described cavity.
As a kind of optimal technical scheme of the present utility model: also comprise an expansion link that is adjustable to the optional position, an end of this expansion link is fixed on to be wiped in the box.The other end of described expansion link is provided with tab, and the area of this tab is greater than the cross-sectional area of expansion link.
As a kind of optimal technical scheme of the present utility model: described expansion link adopts aluminum alloy materials to consist of.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
(1) at the wiping box dust exhaust apparatus is set, air suction opening sucks dust during by wiping, and dust is stored in the dust catcher, thereby reduced writing freely and easily of dust, be conducive to keep the arm cleaning, avoid the people who erases the board to suck a large amount of dusts, thereby reduce the healthy impact that causes;
(2) be provided with open cap at the outer wall of wiping box, this open cap is arranged on the position corresponding with described cavity, adopts this structure, when the dust that can store in dust catcher is too much, and in time cleaning, thus provide convenience for the cleaning of dust catcher;
(3) wipe box and also comprise an expansion link that is adjustable to the optional position, an end of this expansion link is fixed on to be wiped in the box, adopts this structure, and the user that can offer different heights uses, thereby can comprehensively wipe blackboard, and improving blackboard eraser is practicality; The other end of expansion link is provided with tab, the area of this tab adopts this structure greater than the cross-sectional area of expansion link, can so that expansion link one end be fixed on wipe box inside after, tab was stuck in and wipes on the box when expansion link can conveniently pull out or shrink by tab, thereby so that pull out or shrink easy;
(4) expansion link adopts aluminum alloy materials to consist of, and adopts the expansion link of this structure, can improve the hardness of expansion link, and weight reduction, strengthens the stationarity that expansion link connects blackboard eraser.
