Abstract
The utility model discloses a dustproof blackboard eraser comprising a blackboard eraser body. Brushing bristles are fixedly installed at the lower end of the blackboard eraser body. A dust block cover is connected with the lower end face of the blackboard eraser body in a buttoned mode. The height of the dust block cover is less than the height of the brushing bristles. The end portion of the dust block cover is connected with a dust collecting skit edge which faces towards the brushing bristles. When the dustproof blackboard eraser is being used, the dust block cover can prevent chalk powder wiped down from wafting to areas which exceed the blackboard eraser body, the dust collecting skit edge has a certain collection function of the wiped chalk powder and the chalk powder is convenient to clean in a concentrated mode. The dustproof blackboard eraser is simple in structure, convenient to use and good in dustproof effect.
Description
Technical field
The utility model relates to a kind of blackboard eraser, relates in particular to a kind of blackboard eraser that can prevent that chalk from descending slowly and lightly.
Background technology
Current teaching field is more and more paid attention to the improvement of teaching environment, but unique what be difficult to improve is to utilize chalk and blackboard to carry out writing on the blackboard, a large amount of chalk dusts when clearing up blackboard, occurs easily, had a strong impact on the air quality in the classroom, be unfavorable for the healthy of student and classroom.The main path that can improve this phenomenon improves blackboard eraser exactly, make it to increase dust reduction capability, but present dust-proof blackboard eraser mainly is to utilize the structures such as dust arrester, power supply to form, produce easily in use noise, the serious mood that affects the student, the power supply of adding dust-proof blackboard eraser needs the charging of not timing or changes battery, is unfavorable for energy savings.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, clear up easily dust-proof blackboard eraser.
For solving the problems of the technologies described above, the technical solution of the utility model is: dust-proof blackboard eraser, comprise the blackboard eraser body, described blackboard eraser body lower surface is installed with bristle, described blackboard eraser body lower surface is snapped with dust-blocking cover, the height of described dust-blocking cover is less than or equal to the height of described bristle, and described dust-blocking cover end is connected with the control of dust shirt rim towards described bristle.
As preferred technical scheme, described blackboard eraser body upper surface is installed with handle.
As preferred technical scheme, described dust-blocking cover and control of dust shirt rim are set to respectively the plastics lamellar body.
As to improvement of the technical scheme, described dust-blocking cover and control of dust shirt rim are the integral type structure.
Owing to adopted technique scheme, dust-proof blackboard eraser, comprise the blackboard eraser body, described blackboard eraser body lower surface is installed with bristle, described blackboard eraser body lower surface is snapped with dust-blocking cover, the height of described dust-blocking cover is less than or equal to the height of described bristle, and described dust-blocking cover end is connected with the control of dust shirt rim towards described bristle; The beneficial effects of the utility model are: dust-blocking cover can stop that wiping the chalk powder that falls flies away blackboard eraser body zone in addition in use, and the control of dust shirt rim has certain collecting action to the chalk powder of wiping, and is convenient to chalk powder and concentrates cleaning, and is simple in structure, easy to use, good dustproof effect.

Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the profile of Fig. 1;
Among the figure: 1-blackboard eraser body; The 2-bristle; The 3-dust-blocking cover; 4-control of dust shirt rim; The 5-handle.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
As depicted in figs. 1 and 2, dust-proof blackboard eraser comprises blackboard eraser body 1, described blackboard eraser body 1 lower surface is installed with bristle 2, bristle 2 also can replace with structures such as felts, as long as can remove the chalk trace on the blackboard, so the version of bristle 2 is not subjected to the restriction of present embodiment.Described blackboard eraser body 1 lower surface is snapped with dust-blocking cover 3, and the height of described dust-blocking cover 3 prevents that less than or equal to the height of described bristle 2 dust-blocking cover 3 from hindering bristle 2 and removing chalk trace.Described dust-blocking cover 3 ends are connected with the control of dust shirt rim 4 towards described bristle 2, when the chalk trace on the bristle 2 removing blackboards, because the effect of dust-blocking cover 3, chalk powder can not fly away the zone beyond the blackboard eraser body 1, therefore under Action of Gravity Field, can fall by nature after chalk powder is assembled, taking advantage of a situation chalk powder collected in control of dust shirt rim 4, has further stoped chalk powder to fly away.
Dust-blocking cover described in the present embodiment 3 and control of dust shirt rim 4 are set to respectively the plastics lamellar body, and quality is relatively soft, can prevent from scratching blackboard when not hindering bristle 2 cleaning chalk trace.Described dust-blocking cover 3 and control of dust shirt rim 4 are the integral type structure, are convenient to make, and make the assembling processing technology simpler.Described dust-blocking cover 3 is buckled on the blackboard eraser body 1, after a period of time easy to use dust-blocking cover 3 and control of dust shirt rim 4 is taken off and clears up easy accessibility.
Present embodiment can also at described blackboard eraser body 1 upper surface fixed installation one handle 5, use convenient, laborsaving.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
