Abstract
The utility model relates to a novel dust absorption blackboard eraser which comprises a shell body provided with a cavity, wherein absorption holes and eraser hairs are formed in a front cover board of the shell body, a wet absorption object is installed in the shell body, an air suction tube which is communicated with an exhaust fan is installed on a rear cover board of the shell body, and the other end of the air suction tube is communicated with a cavity in the shell body. Dust is absorbed into the cavity through an air suction effect and is immediately absorbed to the wet absorption object to become dust mud, secondary pollution cannot occur, and when the wet absorption object is filled with the dust, the wet absorption object is timely replaced. The novel dust absorption blackboard eraser is simple and reasonable in structure, convenient to use, practical and high in absorption efficiency, and greatly improves air quality in a classroom and teaching and study environment of teachers and students.
Description
Technical field
The utility model belongs to the teaching aid technical field, relates to a kind of novel dust absorption blackboard eraser.
Background technology
During teaching, need to use chalk to write at blackboard, variation along with the content of courses, need the new content of writing on the blackboard, old content just must be wiped it with blackboard eraser, in the blackboard eraser wiping process, chalk dust constantly flies away, these chalk dusts that fly away have everywhere seriously influenced the air quality in the classroom, if breathed in lung, will seriously influence the healthy of Faculty and Students.
Existing dust absorption blackboard eraser mainly is to utilize snag to adsorb, and shortcoming is that adsorption efficiency is low, and the chalk dust that is adsorbed onto in the box also can be poured out again, has seriously influenced air quality.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of adsorption efficiency height and dust is become the novel dust absorption blackboard eraser that plaster adsorbs fully.
The technical method that its technical problem that solves the utility model adopts is: a kind of novel dust absorption blackboard eraser, comprise the housing with cavity, front shroud at housing is provided with adsorption hole and snag is housed, moistening adsorbate is housed in housing, the back shroud of housing is equipped with the aspiration channel that is connected with air exhauster, and the cavity in the other end of aspiration channel and the housing is connected.
Described moistening adsorbate includes moistening sponge and moistening cotton.
The LED lamp pearl that is connected with battery of glint identification effect has been housed in the both sides of described housing.
The beneficial effects of the utility model are: by the air draught effect dust is attracted in the cavity, and be adsorbed onto at once and become dirt mud on the moistening adsorbate, can not produce secondary pollution, when being filled dust, moistening adsorbate just in time changes, it simple and reasonable, practicality easy to use, adsorption efficiency height, greatly improve the air quality in classroom, improved teachers and students' teaching and academic environment.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-snag, 2-front shroud, 3-adsorption hole, 4-back shroud, 5-aspiration channel, 6-LED lamp pearl, the moistening adsorbate of 7-.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, a kind of novel dust absorption blackboard eraser comprises the housing with cavity, is provided with adsorption hole 3 and snag 1 is housed at the front shroud 2 of housing, and moistening adsorbate 7 is housed in housing, and described moistening adsorbate 7 includes moistening sponge and moistening cotton; The back shroud 4 of housing is equipped with the aspiration channel 5 that is connected with air exhauster, and the cavity in the other end of aspiration channel 5 and the housing is connected.The LED lamp pearl 6 that is connected with battery of glint identification effect has been housed in the both sides of described housing.
The utility model attracts dust in the cavity by the air draught effect, and be adsorbed onto at once and become dirt mud on the moistening adsorbate, can not produce secondary pollution, when being filled dust, moistening adsorbate just in time changes, it simple and reasonable, practicality easy to use, adsorption efficiency height, greatly improve the air quality in classroom, improved teachers and students' teaching and academic environment.
