Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide a kind of dust-sucking eraser, accumulation at dust on the blackboard eraser in the teaching process in the prior art, can guarantee that when erasing the board the dust under the blackboard eraser wiping in time is sucked away, to guarantee to make the no dust from flying in the blackboard eraser use.
The technical solution of the utility model is as follows:
A kind of dust-sucking eraser, it comprises a blackboard eraser body, wherein, is provided with housing section at the periphery of described blackboard eraser body, the working face homonymy with described blackboard eraser on described housing section is provided with air suction opening; Described air suction opening is communicated with a dust suction main frame.
Described dust-sucking eraser, wherein, described dust suction main frame is communicated with described housing section by a tube connector.
Described dust-sucking eraser, wherein, described housing section is provided with a switch, and, in described tube connector, be provided with a lead that connects described dust suction main frame and described switch.
Described dust-sucking eraser, wherein, described dust suction main frame and described housing section are wholely set.
Described dust-sucking eraser, wherein, described dust suction main frame is arranged on the track, and this track is provided with along the blackboard base.
Described dust-sucking eraser, wherein, described dust suction main frame adopts storage battery power supply.
A kind of dust-sucking eraser provided by the utility model owing to the air suction opening and the housing section that have adopted at blackboard eraser body periphery, has made things convenient for the operation of the dust suction in the blackboard eraser use, has reduced the dust from flying problem in using, and has reduced the infringement of dust to teacher.

Fig. 2 is the utility model dust-sucking eraser second preferred embodiment schematic diagram;
Fig. 3 is the side cross-sectional schematic of the utility model dust-sucking eraser.
The specific embodiment
Below preferred embodiment of the present utility model is described in detail.
Dust-sucking eraser provided by the utility model, as shown in Figure 1, its can be arranged on blackboard near, for example be arranged on the side and the base of blackboard 100, can on the wall of hanging blackboard a suspension member 101 be set, for example nail or hitching post are provided with a track 102 on the base of blackboard 100, the dust suction main frame 110 of the utility model dust exhaust apparatus can be hung on this track 102, and can move left and right.
In described dust exhaust apparatus, on described suspension member 101, hang a housing section 120 that is used to hold blackboard eraser body 200, as Fig. 1, Fig. 2 and shown in Figure 3, on this housing section 120, be provided with and be provided with air suction opening 121 at working face 201 homonymies of blackboard eraser around blackboard eraser body 200, these air suction openings 121 can be set to several rows of hole, or slotted eye etc., can be arranged on the both sides of blackboard eraser body 200, also can be set to be provided with around blackboard eraser body 200.
The combination fixed form of described blackboard eraser body 200 and described housing section 120 can have a variety of, for example can pass through bolting, perhaps is set to buckle structure, with convenient replacing to blackboard eraser body 200.On described housing section 120, the groove with U type or V-type can be set, with putting into of convenient described blackboard eraser body 200.Can also be provided with on described blackboard eraser body or housing section and have the shank (not shown), by hand-held shank or catch blackboard eraser body 200, the dust that is produced in the process that erases the board can siphon away by air suction opening and dust suction host work.
Described air suction opening 121 is communicated with described dust suction main frame 110, and the work by described dust suction main frame 110 produces suction; Described dust suction main frame 110 can adopt the main frame of present common dust catcher, but is the adapt teaching environment, and the CD-ROM drive motor in the described dust suction main frame 110 should adopt quiet motor.
The operation principle of described dust suction main frame 110 is identical with existing dust collector host operation principle, normally will filter by the dust that air suction opening 121 sucks, and it will comprise a CD-ROM drive motor 111 and filter bag 112 etc. at least, as shown in Figure 1, specifically repeats no more.
In a preferred embodiment of the utility model dust exhaust apparatus, as shown in Figure 1, described dust suction main frame 110 can be arranged on the base track of blackboard, described air suction opening 121 is arranged on the end face on the described housing section 120, described housing section 120 is communicated with dust suction main frame 110 by a tube connector 122, described like this housing section 120 can be removed from suspension member, in the process that is used for blackboard eraser is erased the board, the dust suction, also can directly as same dust catcher do cleaning to the dust in the kerve of blackboard below.Also must be provided with a lead 123 this moment in described tube connector 122, be used for connecting described switch 130 and described dust suction main frame 110.End face in described housing section 120 can also be provided with bristle, is used for the dust of blackboard cleaning below.
