Abstract
The invention discloses a kind of automatic chalk instrument processed, including blackboard body, the first dust catcher, the second dust catcher, the 3rd dust catcher, the first flexible pipe, the second flexible pipe, the 3rd flexible pipe and storage case；First dust catcher, the second dust catcher and the 3rd dust catcher are respectively and fixedly installed to blackboard body left end, right-hand member and upper end, and the first dust catcher, the second dust catcher and the 3rd dust catcher are connected by the first flexible pipe, the second flexible pipe and the 3rd flexible pipe with storage case respectively；The dust that vacuum cleaner sucks is discharged into storage case, changed in the prior art, dust flies upward the situation into human respiratory tract when being erased the board by being provided with multiple vacuum cleaners on blackboard by it；The effect of clean health is accomplished.
Description
Technical field
The present invention relates to teaching applied technical field, especially a kind of automatic chalk instrument processed.
Background technology
Blackboard, it is well known as teaching aid indispensable in teaching process.Writing the font of the whole blackboard of full one
Afterwards, it is necessary to carry out the wiping of blackboard, now chalk dust can be flown upward in classroom, there is different degrees of wound for academics and students
Evil；It is the problem of people need to consider how chalk dust to be carried out into processing.
The content of the invention
Prior art can not meet the needs of people, to make up the deficiencies in the prior art, the present invention is intended to provide one kind is certainly
Move chalk instrument processed.
To realize the technical purpose, the solution of the present invention is：A kind of automatic chalk instrument processed, including blackboard body, the first suction
Dirt device, the second dust catcher, the 3rd dust catcher, the first flexible pipe, the second flexible pipe, the 3rd flexible pipe and storage case；First dust catcher,
Second dust catcher and the 3rd dust catcher are respectively and fixedly installed to blackboard body left end, right-hand member and upper end, and the first dust catcher, second
Dust catcher and the 3rd dust catcher are connected by the first flexible pipe, the second flexible pipe and the 3rd flexible pipe with storage case respectively.
Further technical scheme as the present invention：The storage case is arranged on any side of blackboard body.
Further technical scheme as the present invention：First dust catcher, the second dust catcher and the 3rd dust catcher are logical
Controlling switch is crossed to switch on power socket.
Compared with prior art, the beneficial effects of the invention are as follows：Automatically the chalk instrument processed, it on blackboard by being provided with
Multiple vacuum cleaners, the dust that vacuum cleaner sucks is discharged into storage case, changed in the prior art, it is grey when being erased the board
Dirt flies upward the situation into human respiratory tract；The effect of clean health is accomplished；Overall structure is simple, practical, is adapted to
Promote the use of.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Wherein：Blackboard body 1；First dust catcher 2；Second dust catcher 7；3rd dust catcher 5；First flexible pipe 3；Second flexible pipe
8；3rd flexible pipe 6；Storage case 4.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained all other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, in the embodiment of the present invention, a kind of automatic chalk instrument processed, including blackboard body 1, the first dust catcher 2,
Second dust catcher 7, the 3rd dust catcher 5, the first flexible pipe 3, the second flexible pipe 8, the 3rd flexible pipe 6 and storage case 4；First dust catcher
2nd, the second dust catcher 7 and the 3rd dust catcher 5 are respectively and fixedly installed to the left end of blackboard body 1, right-hand member and upper end, and the first dust catcher
2nd, the second dust catcher 7 and the 3rd dust catcher 5 are connected by the first flexible pipe 3, the second flexible pipe 8 and the 3rd flexible pipe 6 with storage case 4 respectively
It is logical.
Further technical scheme as the present invention：The storage case 4 is arranged on 1 any side of blackboard body.
Further technical scheme as the present invention：First dust catcher 2, the second dust catcher 7 and the 3rd dust catcher 5 are equal
Switched on power socket by controlling switch.
The present invention is when in use：It is first turned on being connected with the first dust catcher 2, the second dust catcher 7 and the wire of the 3rd dust catcher 5
Switch, now the first dust catcher 2, the second dust catcher 7 and the 3rd dust catcher 5 proceed by the suction of dust, it is soft by first
Dust is discharged into storage case 4 by pipe 3, the second flexible pipe 8 and the 3rd flexible pipe 6.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
