Description
Technical field
The utility model the utility model belongs to teaching equipment field, especially relates to a kind of teaching dust absorption blackboard eraser.
Background technology
Blackboard and chalk are a kind of very common educational aids, because it can Reusability and be subject to the welcome of vast teaching person and student, but it also also exists some problems easily bringing simultaneously, wherein maximum problem is exactly while wiping letter written with chalk, chalk dust flies upward everywhere, has had a strong impact on the healthy of teacher and the nearer classmate of distance blackboard.In order to address this problem, existing commercially have some can collect the blackboard eraser of chalk dust, but the ubiquitous problem of these blackboard erasers is complex structure, and cost is higher, is not suitable for applying.
Utility model content
When technical problem to be solved in the utility model is the letter written with chalk on blackboard wiping, reduce flying upward of chalk dust everywhere, the health hazard that reduction teacher and classmate are subject to, a kind of teaching dust absorption blackboard eraser is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of teaching dust absorption blackboard eraser.It is simple that technical problem to be solved is to provide a kind of structure, and cleaning is convenient, without the teaching dust absorption blackboard eraser of dust pollution; The technical scheme solving this technical problem employing is: teaching dust absorption blackboard eraser, comprising: hairbrush, housing, dust catcher; Described dust catcher comprises: suction port, vacuum chamber, dust-collecting cavity, air exhauster, power supply; Described teaching dust absorption blackboard eraser is provided with suction port in hairbrush surrounding, described suction port is connected with the vacuum chamber of the surrounding being arranged on dust absorption blackboard eraser, described vacuum chamber is connected with air exhauster, and described vacuum chamber is connected with dust-collecting cavity, and described power supply is connected with air exhauster.
Further, described dust-collecting cavity can from the dismounting of blackboard eraser inside.
Further, described vacuum chamber adopts flexible pipe to form.
Further, described hairbrush adopts the clear dirt material of cotton to make.
A kind of teaching dust absorption blackboard eraser of the present utility model, start power supply, open air exhauster, the hairbrush of blackboard eraser is in blackboard wiping process, the chalk dust that wiping goes out is sucked vacuum chamber by suction port, chalk dust is stored in dust-collecting cavity, opens dust-collecting cavity in real time by housing and the chalk dust of storage can be cleaned out in time, be convenient to recycle.
The beneficial effects of the utility model are: teacher is when using blackboard eraser, and teaching dust absorption blackboard eraser, can more effectively dust adsorption, prevents chalk dust from flying upward everywhere, realizes obtaining in whole chalk ash collection to dust absorption blackboard eraser more effectively processing.
Accompanying drawing explanation
Fig. 1 is the overall sectional structure chart of the utility model;
In accompanying drawing, the list of parts representated by each label is as follows:
1, hairbrush, 2, dust catcher, 3, housing, 2.1, suction port, 2.2, vacuum chamber, 2.3, dust-collecting cavity, 2.4, power supply, 2.5, air exhauster.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of teaching dust absorption blackboard eraser.It is simple that technical problem to be solved is to provide a kind of structure, and cleaning is convenient, without the teaching dust absorption blackboard eraser of dust pollution; The technical scheme solving this technical problem employing is: teaching dust absorption blackboard eraser, comprising: hairbrush 1, housing 3, dust catcher 2; Described dust catcher 2 comprises: suction port 2.1, vacuum chamber 2.2, dust-collecting cavity 2.3, air exhauster 2.5, power supply 2.4; Described teaching dust absorption blackboard eraser is provided with suction port 2.1 in hairbrush 1 surrounding, described suction port 2.1 is connected with the vacuum chamber 2.2 of the surrounding being arranged on dust absorption blackboard eraser, described vacuum chamber 2.2 is connected with air exhauster 2.5, and described vacuum chamber 2.2 is connected with dust-collecting cavity 2.3, described power supply 2.4 is connected with air exhauster 2.5.
Further, described dust-collecting cavity 2.3 can from the dismounting of blackboard eraser inside.
Further, described vacuum chamber 2.2 adopts flexible pipe to form.
Further, described hairbrush 1 adopts the clear dirt material of cotton to make.
A kind of teaching dust absorption blackboard eraser of the present utility model, start power supply 2.4, open air exhauster 2.5, the hairbrush 1 of blackboard eraser is in blackboard wiping process, the chalk dust that wiping goes out is sucked vacuum chamber 2.2 by suction port, chalk dust is stored in dust-collecting cavity 2.3, opens dust-collecting cavity 2.3 in real time by housing 3 and the chalk dust of storage can be cleaned out in time, be convenient to recycle.
Compared with prior art, its advantage is, teacher is when using blackboard eraser, and teaching dust absorption blackboard eraser, can more effectively dust adsorption, prevents chalk dust from flying upward everywhere, realizes obtaining in whole chalk ash collection to dust absorption blackboard eraser more effectively processing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
