Description

Electric erasing type dustfree soft blackboard

Technical field

The present invention relates to the writing blackboard of culture and education articles for use technical field, especially a kind of electric erasing type dustfree soft blackboard.

Background technology

The use amount of blackboard is very big, at present the blackboard that generally uses mostly with aluminium alloy as framework, as writing panel, as blackboard eraser, realize the purpose of writing and wiping with the wood materials that is coated with blackboard paint or other hardmetal materials with materials such as sponge, cotton hairbrush.In use, the problem of traditional blackboard existence is: write area is limited, can not satisfy user's the demand of writing; Need manually wipe, waste time and energy, and it is not good enough to wipe effect, influence is write once more; The a large amount of dust polluting environments that produce have had a strong impact on the healthy of user, and particularly the high crowd of frequency of utilization such as teacher, student easily causes its breathing problem.At above problem, a lot of people attempt it is made some improvement, find by prior art documents, the soft chalk that curls that the technology soft blackboard of the patent No. 99248378 utilizes the back side to attach some double-sided adhesive bars is write subsides, and technology soft blackboard is collapsible is easy to carry for this, because the double faced adhesive tape at the back side can't keep viscosity for a long time, need often to change, and require metope that higher planarization is arranged, therefore, can't satisfy the teaching demand of long-term use blackboard; The driven blackboard of the patent No. 03112751 has been taked roll type soft blackboard model, and adopted autobalance to avoid the blackboard softpanel because of the gravity effect sideslip, also having used cluth roller control to wipe the word round brush realizes wiping word and keeps two kinds of functions of writing, because it is wiped the word function and finishes by single round brush, and can only finish the word process of once wiping, very difficult assurance is wiped totally writing at every turn; And the model of whole works is a drum-type, has used the distance between tensioning support adjusting driving wheel and driven pulley, yet if softpanel is in tight state all the time, has influenced the service life of blackboard; Again it, the area of this softpanel is limited, the problem of writing surface deficiency when being difficult to solve actual use.

Summary of the invention

A kind of electric erasing type dustfree soft blackboard of providing at the deficiencies in the prior art is provided, and this blackboard has the automaticity height, and is easy to use, writes facility, good dedusting effect.

The concrete technical scheme that realizes the object of the invention is:
