Description
Technical field
This utility model relates to a kind of teaching aid, especially a kind of dust suction automatic blackboard eraser.
Background technology
Along with social progress and the quickening of social rhythm, teaching profession's disease rate presents in the trend risen year by year, occupation disease
Variation direction is developed, pneumoconiosis that wherein dust causes and various acute and chronic respiratory tract disease be in China's occupation disease at present
Mainly, harm is the most serious and widest a kind of.Teachers in primary and middle schools' respiratory system Prevalence Rate of Chronic Diseases is higher, common for chronic pharynx
Inflammation and vocal cords disease.Owing to containing carcinogen in dust, Center for Disease Control of China data shows, 38,000,000 sole duties of China
Teacher's cancer morbidity has accounted for the 20% of Nattonal Cancer total incidence, and 8 times for ordinary group strong.The common chalk of China is many
Individual workshop for " three without " produces, they dose in a large number in raw materials for production to maximize profit cheap, damage
The harmful substances such as the pulverized limestone of user health, dry powder, particularly produce when writing and wipe and can not be inhaled by human body in a large number
The dust received, severe contamination teaching environment, affect the healthy of Faculty and Students.
Summary of the invention
The purpose of this utility model is, it is provided that the dust suction automatic blackboard eraser of a kind of automatic erasing dust suction.
This utility model solves its technical problem and be the technical scheme is that a kind of dust suction automatic blackboard eraser, including
Blackboard, it is characterised in that also include substrate, the aspiration of negative pressure device, blackboard is fixed on substrate, blackboard is fixedly installed one past
The automatic blackboard eraser of multiple movement, automatic blackboard eraser hollow, a suction port is respectively set in the both sides of automatic blackboard eraser, the most black
Blackboard eraser is connected with the aspiration of negative pressure device, is provided with a slide rail on substrate, and automatic blackboard eraser one end is arranged on slide rail, and and negative pressure
Vacuum cleaner connects.
Of the present utility model it is further arranged to: one end of automatic blackboard eraser is provided with a hollow lead, and slide rail sets
Having chute, lead to be arranged in chute, lead is connected with the aspiration of negative pressure device by pipeline.
Of the present utility model it is further arranged to: described slide rail is arranged on the underface of automatic blackboard eraser, on slide rail
Being provided with a dust groove, dust groove is corresponding with automatic blackboard eraser, is respectively provided with water-flushing device, water receiving tank, powder in the both sides of dust groove
Dirt groove tilts from water-flushing device one end to water receiving tank one end.
Said structure when in use, automatic blackboard eraser reciprocatingly move carry out automatic blackboard cleaning when, negative pressure
Vacuum cleaner carries out dust suction process by the suction port of the both sides of automatic blackboard eraser, and the dust absorbing that wiping is got off is clean, reaches nothing
The process of dirt, it is ensured that dust indiffusion, does not blots clean dust fall down even if having, owing to the water of dust groove directly receives,
The phenomenon of dust recycling will not occur again, utilize water-flushing device regularly to clear up holding clean, can not only automatic blackboard cleaning, also
Can guarantee that absolute dustlessization.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment；
Detailed description of the invention
Understanding with reference to Fig. 1, this utility model one dust suction automatic blackboard eraser, including blackboard 2, substrate 1, the aspiration of negative pressure device
4, blackboard 2 is fixing on substrate 1, is fixedly installed an automatic blackboard eraser moved back and forth 3, in automatic blackboard eraser 3 on blackboard 2
Sky, respectively sets a suction port 31 in the both sides of automatic blackboard eraser 3, and automatic blackboard eraser 3 is connected with the aspiration of negative pressure device 4, at base
Plate 1 is provided with a slide rail 5, and automatic blackboard eraser 3 one end is arranged on slide rail 5, and connects with the aspiration of negative pressure device 4, automatic blackboard
The one end wiping 3 is provided with a hollow lead 32, and slide rail 5 is provided with chute 51, and lead 32 is arranged in chute 51, lead
32 are connected with the aspiration of negative pressure device 4 by pipeline 41, and described slide rail 5 is arranged on the underface of automatic blackboard eraser 3, on slide rail 5
Being provided with a dust groove 52, dust groove 52 is corresponding with automatic blackboard eraser 3, is respectively provided with water-flushing device 6 in the both sides of dust groove 52, connects
Tank 7, dust groove 52 tilts from water-flushing device 6 one end to water receiving tank 7 one end.
Obviously, above-described embodiment is only used to done citing is clearly described, and not restriction to embodiment.
To those of ordinary skill in the art, change or the change of other multi-form can also be made on the basis of the above description
Dynamic.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or change
Dynamic still in protection domain of the present utility model.
