Description
Technical field
The utility model relates to field of Educational Technology, particularly relates to a kind of education and instruction blackboard.
Background technology
Teaching is the distinctive personnel training activity of a kind of mankind that the religion of teacher and of student form.By this activity, teacher has object, planned and organized ground guiding student actively consciously to learn and accelerates to grasp Cultural Science rudimentary knowledge and basic skills, promotes that the many-sided quality of student improves comprehensively, makes them become people required for society.
At present, no matter the education activities in educational training or school, generally still adopt traditional teaching method, namely teacher gives lessons on dais, with chalk, the main contents book of giving lessons is write on the blackboard simultaneously, thus erase the board with blackboard eraser and just become necessary work, but blackboard wiping adopts blackboard eraser to carry out wiping at present, such wiping efficiency is low, and work is slight large, simultaneously in the process erased the board, chalk powder flies upward, these chalk powders, once in suction body, can cause no small infringement to the health of student and teacher.Therefore, for solving the problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of education and instruction blackboard.
The utility model is achieved through the following technical solutions:
A kind of education and instruction blackboard, comprise blackboard, described blackboard upper/lower terminal is provided with gathering sill, the roller that described gathering sill inside is connected with wiping stand contacts, the U-shaped structure of described wiping stand, and is provided with wiping handle outside wiping stand, cleaning cotton is provided with between described wiping stand and blackboard surface, the both sides of described wiping stand are provided with several adsorption holes, and described adsorption hole communicates with the suction pump being arranged on wiping stand inside, are provided with ash collecting box below described wiping stand.
As preferably, described cleaning cotton is embedded on wiping stand.
As preferably, the rounded or strip of described adsorption hole.
As preferably, described ash collecting box upper end communicates with the air draft passage of wiping stand inside.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model can moving around by wiping stand, the cleaning cotton on it is utilized to carry out wiping to blackboard surface, such wiping efficiency is high, and labour intensity is low, simultaneously in wiping process, the suction pump of wiping stand inside starts the adsorbing powder dust will produced by adsorption hole, and is collected in ash collecting box, and such chalk powder can not fly upward everywhere, thus make teacher and student suck chalk powder, ensure that the health of teacher and student.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: 1. blackboard; 2. wiping stand; 3. roller; 4. gathering sill; 5. wiping handle; 6. cleaning cotton; 7. adsorption hole; 8. suction pump; 9. ash collecting box.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 2, a kind of education and instruction blackboard, comprise blackboard 1, on described blackboard 1, lower two ends are provided with gathering sill 4, the roller 3 that described gathering sill 4 inside is connected with wiping stand 2 contacts, the U-shaped structure of described wiping stand 2, and be provided with wiping handle 5 outside wiping stand 2, cleaning cotton 6 is provided with between described wiping stand 2 and blackboard 1 surface, described cleaning cotton 6 is embedded on wiping stand 2, after such use one end time, be convenient to change cleaning cotton 6, moving around like this by wiping stand 2, the cleaning cotton 6 pairs of blackboard surfaces on it are utilized to carry out wiping, such wiping efficiency is high, and labour intensity is low.
The both sides of described wiping stand 2 are provided with several adsorption holes 7, the rounded or strip of described adsorption hole 7.Described adsorption hole 7 communicates with the suction pump 8 being arranged on wiping stand 2 inside, is provided with ash collecting box 9 below described wiping stand 2, and described ash collecting box 9 upper end communicates with the air draft passage of wiping stand 2 inside.In wiping process, the suction pump 8 of wiping stand 2 inside starts the adsorbing powder dust will produced by adsorption hole 7, and is collected in ash collecting box 9, and such chalk powder can not fly upward everywhere, thus make teacher and student suck chalk powder, ensure that the health of teacher and student.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
