Description
(1) technical field
The utility model relates to a kind of blackboard eraser, particularly the anti-dust multifunctional blackboard eraser of one.
(2) background technology
In teaching process, for the ease of memory and the understanding of student, all can use blackboard and carry out writing on the blackboard, blackboard writes and mostly uses chalk, letter written with chalk can produce dust when wiping with blackboard eraser, can produce very adverse influence after the dust of chalk flies upward and sucked by human body in atmosphere to the health of human body.And sometimes can wipe clean because student's strength is less when erasing the board, and student wipes blackboard and also can feel that arm is ached.
(3) utility model content
The utility model, in order to make up the deficiencies in the prior art, provides the anti-dust multifunctional blackboard eraser that a kind of structure is simple, easy to use.
The utility model is achieved by the following technical solution:
A kind of anti-dust multifunctional blackboard eraser, comprises blackboard eraser main body, it is characterized in that: described blackboard eraser main body lower ending opening, and upper end is provided with one can the dust lid of folding; Be provided with cylindrical dust box in described blackboard eraser main body top, this dust box external wall of upper portion is provided with an equidistant dust hole of circle; Described dust box lower end is connected with power house, and this power house top is fixed with motor, and power house inwall is fixed with power supply, and outer wall is provided with gauge tap; Described motor, power supply, gauge tap is by wired in series together; Described motor rotary shaft is connected with flabellum center; Flabellum center is connected with three flabellums, and every sheet flabellum is provided with hairbrush; Described fan leaf, power house, dust box and blackboard eraser body outer wall form annular dust passage, and this dust passage is communicated with dust box by dust hole.
Described hairbrush end flushes with blackboard eraser main body lower ending opening.
When the utility model uses, be placed on by blackboard eraser on blackboard, open gauge tap, motor drives flabellum to rotate, hairbrush on fan leaf also rotates thereupon, hairbrush is inswept blackboard, sweeps up chalk powder, intercepts owing to there being blackboard eraser body outer wall, dust can not fly to outside blackboard eraser, but along with fan produce centrifugal force and blast, fly to blackboard eraser main body upper end along dust passage, entered in dust box by dust hole.When whole blackboard wipes, closing control switch, opens the dust lid on blackboard eraser main body top, is outwelled by chalk powder.
The beneficial effects of the utility model are: the utility model structure is simple, easy to use, not only solve the problem that the dust that causes when ordinary blackboard eraser erases the board is too much, replace muscle power simultaneously with electric power, the muscle power of the no longer at substantial of making to erase the board.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is fan structure schematic diagram of the present utility model.
In figure, 1 blackboard eraser main body, 2 dust boxes, 3 power houses, 4 motor, 5 power supplys, 6 flabellums, 7 hairbrush, 8 gauge taps, 9 dust lids, 10 dust passage, 11 flabellum centers, 12 dust holes.
(5) detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises blackboard eraser main body 1, described blackboard eraser main body 1 lower ending opening, and upper end is provided with one can the dust lid 9 of folding; Be provided with cylindrical dust box 2 in described blackboard eraser main body 1 top, this dust box 2 external wall of upper portion is provided with an equidistant dust hole 12 of circle; Described dust box 2 lower end is connected with power house 3, and this power house 3 top is fixed with motor 4, and power house 3 inwall is fixed with power supply 5, and outer wall is provided with gauge tap 8; Described motor 4, power supply 5, gauge tap 8 is by wired in series together; The rotating shaft of described motor 4 is connected with flabellum center 11; Flabellum center 11 is connected with three flabellums 6, and every sheet flabellum 6 is provided with hairbrush 7; Described flabellum 6, power house 3, dust box 2 form annular dust passage 10 with blackboard eraser main body 1 outer wall, and this dust passage 10 is communicated with dust box 2 by dust hole 12.Described hairbrush 7 end flushes with blackboard eraser main body 1 lower ending opening.
During use, be placed on by blackboard eraser on blackboard, open gauge tap 8, motor 4 drives flabellum 6 to rotate, hairbrush 7 on flabellum 6 also rotates thereupon, hairbrush 7 is inswept blackboard, sweeps up chalk powder, intercepts owing to there being blackboard eraser main body 1 outer wall, dust can not fly to outside blackboard eraser, but along with fan produce centrifugal force and blast, fly to blackboard eraser main body 1 upper end along dust passage 10, entered in dust box 2 by dust hole 12.When whole blackboard wipes, closing control switch 8, opens the dust lid 9 on blackboard eraser main body 1 top, is outwelled by chalk powder.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
