Description
Technical field
The utility model belongs to a kind of educational aid, relates in particular to a kind of dust absorption blackboard eraser.
Background technology
At present, on the blackboard eraser body of selling on the market, only have some felts, when erasing the board, can produce a lot of dust, dust flies away everywhere, affects ambient air, and people suck dust and easily suffer from breathing problem, and people's health is caused to bad impact.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of dust absorption blackboard eraser is provided.
The purpose of this utility model is achieved in that a kind of dust absorption blackboard eraser, comprise blackboard eraser body and the felt that is arranged on upper surface, blackboard eraser body bottom, described blackboard eraser body interior is provided with a small-sized air exhauster, on described blackboard eraser body upper surface, air inlet is set, the place, air port of described air exhauster arranges dust-absorbing groove, the bottom of described dust-absorbing groove sets out air port, and described air outlet place is provided with the filter screen of Chalk-dust filtering, and described filter screen is movably arranged on air outlet place; Described blackboard eraser body interior arranges irregular air channel, and described irregular air channel is connected with air inlet and dust-absorbing groove.
Described felt is stripe-arrangement on described blackboard eraser body, and described air inlet is arranged between two between adjacent felt bar, and felt bar and air inlet are staggered.
One outwardly directed projection is set on the edge of described filter screen.
Described irregular air channel is fold-line-shaped air channel.
Described irregular air channel is contoured shape air channel.
The middle part of described blackboard eraser body leading flank is provided with switch.
The middle part of the top rectangular surfaces of described blackboard eraser body is provided with battery case.
Described air exhauster is provided with four flabellums.
Described filter screen is movably arranged on the blackboard eraser body end face at air outlet place by buckle structure.
The utility model provides a kind of dust absorption blackboard eraser, simple in structure, and practical function has solved people effectively when erasing the board, the healthy problem of impact in dust suction body.On the side of described blackboard eraser body, be provided with a dust-absorbing groove, dust-absorbing groove bottom sets out air port, and by strainer filtering dust, utilize air exhauster by air inlet by dust suction blackboard eraser body interior, the dust of strainer filtering air outlet, dust is stayed dust-absorbing groove inside, has avoided human body to suck dust; Described filter screen is movably arranged on air outlet place, and an outwardly directed projection is set on the edge of described filter screen, and pull out convex edge and can open filter screen and pour out the dust in dust-absorbing groove, simplicity of design, easy to use; Described blackboard eraser body interior arranges irregular air channel, dust can be introduced in dust-absorbing groove by irregular air channel; Described felt is stripe-arrangement on described blackboard eraser body, and described air inlet is arranged between two between adjacent felt bar, and felt bar and air inlet are staggered, and make full use of the area of blackboard eraser, improves dust collection efficiency; Described irregular air channel is fold-line-shaped air channel, clashes into fold-line-shaped air channel and makes dust fall process through a dirt after dust is introduced in air channel, more easily by dust-absorbing groove, sucked, and inner unrest flies in air channel can not produce dust; Described filter screen is movably arranged on by buckle structure on the blackboard eraser end face at air outlet place, and buckle structure can be opened and can lock, and while using blackboard eraser, filter screen is locked on blackboard eraser end face, in the time of need to clearing up the inner dust of dust-absorbing groove, open snap close and can pull out filter screen, pour out dust, simplicity of design, easy to use.
