Description
Technical field
The utility model relates to blackboard eraser, is specifically related to a kind of dust-free blackboard sassafras system.
Background technology
At present, the common blackboard eraser that we use cannot strong adsorption chalk dust, use at every turn blackboard eraser always can make be all over the body ash, to be afraid of that beating several lower blackboard eraser could continue to use toward contact when second time uses, to have kicked up again among process a lot of chalk dusts, and when blackboard eraser uses after a period of time, the adsorption capacity of the aging rear blackboard eraser of its felt hair is more and more weak, the chalk dust kicked up not only has been made dirty environment and clothing, and unescapable suction also can affect our health.
Utility model content
For the problems referred to above that the blackboard eraser of existing use exists, the utility model provides a kind of a kind of dust-free blackboard sassafras system avoiding chalk dust disorderly to waft.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of dust-free blackboard sassafras system, comprise air blast, dust bag, main pipeline, branch pipe(tube), blackboard eraser, it is characterized in that: the air outlet of air blast is provided with dust bag, the air inlet of air blast is provided with excessive pipeline; The right-hand member of excessive pipeline is provided with main pipeline; The right-hand member of main pipeline is provided with some branch pipe(tube)s, the air inlet of branch pipe(tube) is provided with blackboard eraser; Described blackboard eraser comprises housing, bristle, handle; Described housing is a kind of cuboid with cavity body, the left end of housing is provided with some bristles and through hole, the handle of circular arc is provided with at the right-hand member of housing, the lower end of housing is provided with outlet passageway, outlet passageway and cavity body, through hole are interconnected, and the air inlet of outlet passageway and branch pipe(tube) is interconnected.
Further, described dust bag is that a kind of cotton with gas permeability is made.
Further, described dust bag is interconnected by the outlet passageway on air blast and main pipeline, branch pipe(tube) and blackboard eraser.
Further, described main pipeline is a kind of pvc pipe.
Further, described branch pipe(tube) is a kind of rubber hose, is provided with spiral steel wire inside rubber hose.
Further, described excessive pipeline is a kind of truncated cone-shaped structure.
The beneficial effects of the utility model are: a kind of dust-free blackboard sassafras system having manufactured a kind of environmental protection, and structure is simple, effectively can adsorb chalk dust, and maintenance environment is clean and tidy and avoid chalk dust to suck human body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
According to Fig. 1, a kind of dust-free blackboard sassafras of the utility model system, comprise air blast (1), dust bag (2), main pipeline (3), branch pipe(tube) (4), blackboard eraser (5), it is characterized in that: the air outlet of air blast (1) is provided with dust bag (2), the air inlet of air blast (1) is provided with excessive pipeline (6); The right-hand member of excessive pipeline (6) is provided with main pipeline (3); The right-hand member of main pipeline (3) is provided with some branch pipe(tube)s (4), the air inlet of branch pipe(tube) (4) is provided with blackboard eraser (5); Described blackboard eraser (5) comprises housing (11), bristle (12), handle (13); Described housing (11) has the cuboid of cavity body (14) for one, the left end of housing (11) is provided with some bristles (12) and through hole (15), the handle (13) of circular arc is provided with at the right-hand member of housing (11), the lower end of housing (11) is provided with outlet passageway (16), outlet passageway (16) and cavity body (14), through hole (15) are interconnected, and the air inlet of outlet passageway (16) and branch pipe(tube) (4) is interconnected.
Further, described dust bag (2) is made for a kind of cotton with gas permeability.
Further, described dust bag (2) is interconnected by the outlet passageway (16) on air blast (1) and main pipeline (3), branch pipe(tube) (4) and blackboard eraser (5).
Further, described main pipeline (3) is a kind of pvc pipe.
Further, described branch pipe(tube) (4) is a kind of rubber hose, is provided with spiral steel wire (17) inside rubber hose.Its objective is: in order to do not allow the exhausting strength of air blast (1) rubber hose inhale be out of shape, because steel wire (17) has certain bendability and supportive.
Further, described excessive pipeline (6) is a kind of truncated cone-shaped structure.
Embodiment: air blast (1) is placed on outside teacher, blackboard eraser (5) is entered near the blackboard of each teacher by branch pipe(tube) (4), ensure when use blackboard eraser (5), branch pipe(tube) (4) can swing on blackboard along with blackboard eraser (5), start air blast (1), the air inlet of air blast (1) is successively by excessive pipeline (6), main pipeline (3), branch pipe(tube) (4) is drawn into the chalk dust near blackboard eraser (5) air outlet of air blast (1) by through hole (15), and chalk dust is transported to dust bag (2) the inside, chalk dust has been stayed on the inwall of dust bag (2), air-flow has been transported to the external world by dust bag (2), so a kind of dust-free blackboard sassafras (5) system having manufactured a kind of environmental protection, structure is simple, effectively can adsorb chalk dust, maintenance environment is clean and tidy and avoid chalk dust to suck human body.
The foregoing is only the utility model preferred embodiment; not thereby claim of the present utility model is limited; so the equivalent structure change that all utilization the utility model descriptions and diagramatic content are made, be all included in protection domain of the present utility model.
