Description

A kind of blackboard eraser with the dust container

Technical field

The utility model relates to a kind of blackboard eraser, relates to a kind of blackboard eraser with the dust box in particular, is mainly used in teaching field.

Background technology

Blackboard eraser on the existing market only has erase feature mostly, can not the centralized collection dust, and wipe finish after, patting blackboard eraser can cause dust to fly upward everywhere, this has not only polluted environment, simultaneously, also the healthy of numerous teachers and students in serious harm, and be especially true to the worker who is engaged in educational undertaking for a long time; For avoiding dust to fly upward everywhere, also occur some in the market and can collect the electric blackboard eraser of dust automatically, but inconvenience and cleaning dust are cumbersome when using owing to electric blackboard eraser, secondly, electronic unit is subjected to the erosion of dust easily, reduce greatly its service life and its cost higher, be unfavorable for promoting.

Summary of the invention

For the dust that solves existing blackboard eraser technical problem such as easily collecting and cleaning not; The utility model provides a kind of blackboard eraser with the dust container, and it is simple in structure, and is with low cost, can effectively avoid dust to fly upward everywhere, simultaneously, also can make things convenient for the cleaning of dust.

For solving above technical problem, the technical scheme that the utility model is taked is a kind of blackboard eraser with the dust container, it includes wiping board, described wiping board one side centre is provided with wipes cotton, it is characterized in that described wiping board below is provided with lid and puts the dust container of wiping cotton, this dust container has the open-ended cavity of a collection dust, and the opening part of described open-ended cavity is complementary with the cotton size of wiping.

Further, size is less than size around its top around the described dust container bottom, and it laterally reaches and vertically all forms a trapezoidal shape.

The beneficial effects of the utility model are:

1. can prevent effectively that dust from flying upward, and reduces the suction of human body to dust everywhere;

2. convenient collection and cleaning to dust can not polluted the field of employment.

Specific embodiments

Below in conjunction with accompanying drawing the utility model embodiment is described further:

Extremely shown in Figure 2 as Fig. 1, a kind of blackboard eraser of the utility model with the dust container, it includes wiping board 1, described wiping board 1 one side centres are provided with wipes cotton 2, blackboard eraser is collected and the cleaning dust for convenience, described wiping board 1 below is provided with lid and puts the dust container 3 of wiping cotton 2, this dust container 3 has the open-ended cavity 31 of a collection dust, the opening part of described open-ended cavity 31 is complementary with cotton 2 sizes of wiping, adopt this structure, when blackboard eraser wipe finish after, cotton 2 lids of the wiping that sticks chalk dust are put on the open-ended cavity 31 of dust container 3, pick up wiping board 1 again and pat table top,, stick in the dust of wiping on cotton 2 and can come off fully in the open-ended cavity 31 of dust container 3 along with the shake of wiping board 1 with dust container 3 with dust container 3; And pat table top after a period of time, dust container 3 can be separated with wiping board 1, wiping cotton 2, so only need to pour the dust in the open-ended cavity 31 of dust container 3 into dustbin and can finish cleaning, so not only do not pollute, simultaneously, also can effectively avoid flying upward of dust everywhere, reduce the dust that human body sucks, avoid the harm of dust human body.

In the present embodiment, for improving the overall appearance of blackboard eraser, size is less than size around its top around described dust container 3 bottoms, it laterally reaches the longitudinal cross-section and all forms a trapezoidal shape, be arranged to trapezoidal shape, not only can increase the overall appearance of blackboard eraser, simultaneously, also can make and wipe cotton 2 tighter with 3 clampings of dust container, make that dust container 3 can not drop when moving blackboard eraser; Certainly, dust container 3 also can not be arranged on trapezoidal shape, and is square such as also being arranged on, and can reach identical purpose equally, but square owing to being arranged on, it is too stiff that the outward appearance of blackboard eraser seems, therefore, the embodiment of present embodiment is a preferred implementation.

The foregoing description should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
