Include the blackboard eraser, be located the dust extraction above the blackboard eraser, two -layer about dust extraction divide into, the upper strata is solar cell panel, and the lower floor is miniature dust catcher, and the interface of solar cell panel and miniature dust catcher is provided with the notch, is provided with flexible pipe in the notch. The utility model provides a chalk end problem of flying upward everywhere, in clearance letter written with chalk vestige, do not lead to the fact dust pollution, purify the teaching environment, lighten the difficult problem of clean blackboard, chalk dust.
Description
Technical field
This utility model belongs to realia field, particularly relates to automatic dust-catching type blackboard eraser.
Background technology
Although modern teaching realizes the teaching method of Multifunctional multimedia, but can not completely disengage from for chalk, blackboard this tradition teaching aid.Teacher passes through chalk writing on the blackboard content of courses on blackboard, knowledge is taught to student by the form of word, but when using complete in blackboard space, need letter written with chalk is wiped, writing on the blackboard could be continued, in erase process, chalk powder flies upward in atmosphere, the teacher near dais, student is made to suffer the pollution of dust, long-term on pulmonary's generation impact, threat teacher's is healthy, especially child is in the stage of growth promoter, sucks too much dust and causes respiratory tract disease or affect physical growth.Additionally, dust dances in the air everywhere, on lectern, the desktop of front-seat student, books, clothes are all stained with chalk powder, are difficult to clean up, bring puzzlement to normal teaching.
Utility model content
For the deficiencies in the prior art, this utility model provides automatic dust-catching type blackboard eraser, it is possible to automatically collect chalk powder in the space closed, not contaminated air.
For solving above-mentioned technical problem, of the present utility model it is achieved through the following technical solutions:
Automatic dust-catching type blackboard eraser, it is characterized in that and includes blackboard eraser, is positioned at the dust exhaust apparatus above blackboard eraser, described dust exhaust apparatus is divided into upper and lower two-layer, upper strata is solar panel, lower floor is micro-cleaner, the interface of solar panel and micro-cleaner is provided with notch, is provided with telescoping tube in notch.
Further, described telescoping tube one end is connected with the dust removal port of micro-cleaner, and the other end stretches out notch.
Further, the switch controlling dust exhaust apparatus it is provided with at the outer surface of micro-cleaner.
Further, being provided with anti-slide opening in dust exhaust apparatus both sides, described anti-slide opening is the circular depressed of multiple random arrangement.
Compared with prior art, it has the beneficial effect that this utility model solves the problem that chalk powder flies upward everywhere to this utility model, while cleaning letter written with chalk vestige, does not cause dust pollution, purifies teaching environment, alleviates a difficult problem for cleaning blackboard, chalk dust.By arranging micro-cleaner, easily collect chalk foam, in the space closed, chalk foam is stored, and concentration is discharged；Utilize solar panel, provide the energy to the micro-cleaner in blackboard eraser, replace manually realizing cleaning, save the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of symbols: 1, blackboard eraser, 2, micro-cleaner, 3, solar panel, 4, switch, 5, notch, 6, telescoping tube, 7, anti-slide opening.
Detailed description of the invention
Referring to Fig. 1, provide detailed description of the invention of the present utility model, be used for this utility model is described further, but this utility model is not limited to specific embodiment discussed below.
Embodiment 1:
The automatic dust-catching type blackboard eraser that the present embodiment provides, including blackboard eraser 1, it is positioned at the dust exhaust apparatus above blackboard eraser 1, described dust exhaust apparatus is divided into upper and lower two-layer, upper strata is solar panel 3, lower floor is micro-cleaner 2, the interface of solar panel 3 and micro-cleaner 2 is provided with notch 5, is provided with telescoping tube 6 in notch 5.
Simply show the schematic diagram of automatic dust-catching type blackboard eraser in the present embodiment, blackboard eraser is flexible foam, sponge etc., dust exhaust apparatus above blackboard eraser can be encapsulated in housing, between housing with blackboard eraser bonding, housing is divided into upper and lower two-layer, and bilevel center-aisle is used for holding on micro-cleaner for collecting the telescoping tube of dust.
The sponge direction of the suction port alignment blackboard eraser of micro-cleaner, when starting micro-cleaner, chalk dust is collected in telescoping tube by suction port.Solar panel is used for providing electric energy for micro-cleaner, utilizes natural energy resources, unduly consumes other energy, is conducive to economizing on resources.Solar panel drives the connected mode of micro-cleaner to be known to the skilled person content, is no longer described in detail in this utility model.When the blackboard eraser of the present embodiment does not have electricity, the ground being placed on sunlight conveniently can charge to micro-cleaner automatically, reach to save energy purpose.
Described telescoping tube 6 one end is connected with the dust removal port of micro-cleaner 2, and the other end stretches out notch 5.When having collected chalk dust, telescoping tube is pulled out from notch, concentrate cleaning chalk dust, it is to avoid dust from flying, after cleaning out, bounce back telescoping tube placement from notch.Telescoping tube is elastic material or plastic material.
Outer surface at micro-cleaner 2 is provided with the switch 4 controlling dust exhaust apparatus, is opened by what switch or is closed, controls dust exhaust apparatus duty.
Be provided with anti-slide opening 7 in dust exhaust apparatus both sides, described anti-slide opening is the circular depressed of multiple random arrangement, and user grasps both sides, strengthens frictional force, it is simple to abutted in by Blackboard having automatic dust absorbing function sassafras and treat that collecting zone carries out dust collection work.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
