Abstract
The utility model discloses a novel electronic dust absorption blackboard eraser, it includes the blackboard eraser body and sets up dust extraction above that, dust extraction is including setting up the back lid at blackboard eraser body back, and the symmetry sets up dust absorption fan and dust collection channel in the hou gai both sides, with the dust collection channel intercommunication and set up the dust -collecting box at the hougai back, provides the electric energy and sets up the power pack of covering after, the elasticity press the switch who sets up in the hougai both sides for the fan, the utility model discloses long service life, effect of dust collection are good, and on -off control is convenient.
Description
Technical field
The utility model is related to a kind of tutor auxiliary platform apparatus and in particular to a kind of electric dust-absorbing blackboard eraser.
Background technology
Although existing dust absorption blackboard eraser delicate structure, it is not durable, service life is short, for ease of its bristle of dust suction or brush
Cloth arrangement is sparse, and impact wipes effect and is unfavorable for Long-Time Service.
Utility model content
The purpose of this utility model is to provide a kind of electric dust-absorbing blackboard eraser it is intended to improve the wiping effect of blackboard eraser
And pick-up performance, and simplify switch control rule, increase operation convenience.
The technical solution adopted in the utility model is for achieving the above object:
A kind of electric dust-absorbing blackboard eraser, including blackboard eraser body and the dust exhaust apparatus being disposed thereon, described dust suction
Device includes being arranged on the bonnet at blackboard eraser body back, is symmetricly set on dust absorption fan and the dust passage of bonnet both sides, with
Dust channel connection and be arranged on the dust-collecting box at bonnet back, power pack electric energy being provided and covering after being arranged on for fan, if
Put elasticity in bonnet both sides by compressing switch；
Further, described dust-collecting box is made up of transparent material, is separable to be arranged on bonnet back；
Further, described bonnet is in u font；
Further, described elasticity by the cantilever piece being connected with bonnet including one end that compresses switch, be clamped in cantilever piece and bonnet
Between spring, be arranged on cantilever piece and after the power contact that covers.
The beneficial effect of the utility model embodiment is:
The utility model improves on the basis of existing blackboard eraser body, can adopt existing blackboard eraser, its
Wiping effect is good, long service life, and two fans using its both sides carry out dust suction, can effectively absorb chalk dust around, inhales
Dirt effect is good, and elasticity is easy to operate with by compressing switch, and individually need not transfer switch, hand-held simple pressing can be opened.
Brief description
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the elevational schematic view of Fig. 1.
Wherein, 1- blackboard eraser body；2- bonnet；3- dust absorption fan；4- dust passage；5- dust-collecting box；6- power pack；7- bullet
Property is by compressing switch；8- cantilever piece；9- spring；10- power contact.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is illustrated:
As shown in figure 1, a kind of electric dust-absorbing blackboard eraser, including blackboard eraser body 1 and the dust suction dress being disposed thereon
Put, described dust exhaust apparatus includes being arranged on the bonnet 2 at blackboard eraser body 1 back, is symmetricly set on the dust absorption fan of bonnet 2 both sides
3 and dust passage 4, connect and be arranged on the dust-collecting box 5 at bonnet 2 back with dust passage 4, provide electric energy and setting for fan 3
Power pack 6 on bonnet 2, is arranged on the elasticity of bonnet 2 both sides by compressing switch 7；Described dust-collecting box 5 is made up of transparent material,
It is separable to be arranged on bonnet 2 back；Described bonnet 2 is in u font；Described elasticity 7 includes one end and bonnet 2 even by compressing switch
The cantilever piece 8 connecing, the spring 9 being clamped between cantilever piece 8 and bonnet 2, the power contact being arranged on cantilever piece 8 and bonnet 2
10.
In the utility model, bonnet 2 is buckled in the back of blackboard eraser body 1, is easy to the replacing of blackboard eraser body 1；Bullet
Property by compress switch 7 be located at bonnet 2 both sides, the started by press dust absorption fan 3 when being easy to hand-held, swing blackboard wiping during inhale
The chalk dust of surrounding is absorbed by dirt fan 3, collects in dust-collecting box 5 through dust passage 4, and transparent and dismountable dust-collecting box 5 is just
Dispose chalk dust in time；Power pack 6 adopts chargeable form, so uses more convenient；Elasticity is by 7 bags that compress switch
Include one end cantilever piece 8 being connected with bonnet 2, the spring 9 being clamped between cantilever piece 8 and bonnet 2, be arranged on cantilever piece 8 and after
Power contact 10 on lid 2, only needs slight amount can open dust absorption fan 3, the mechanism of cantilever piece 8 can be without limit when hand-held
Hand position processed.
Finally it is noted that the foregoing is only the preferred embodiment of utility model, it is not limited to practicality
New, although being described in detail to utility model with reference to the foregoing embodiments, for a person skilled in the art, its
Still the technical scheme described in foregoing embodiments can be modified, or wherein some technical characteristics are equal to
Replace.Within all spirit in utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in reality
Within new protection domain.
