Description

Electric erasing dust-free soft blackboard

technical field

The invention relates to a writing blackboard in the technical field of cultural and educational supplies, in particular to an electrically erasable dust-free soft blackboard.

Background technique

The use of blackboards is very large. Most of the blackboards currently in use use aluminum alloy as the frame, wooden materials sprayed with blackboard paint or other hard metal materials as the writing panel, and materials such as sponges and cotton brushes as blackboard erasers. Realize the purpose of writing and erasing. In the process of use, the problems existing in the traditional blackboard are: the writing area is limited, which cannot meet the writing needs of users; manual erasing is required, which is time-consuming and laborious, and the erasing effect is not good, which affects re-writing; a large amount of dust generated pollutes the environment, It has seriously affected the health of users, especially teachers, students and other people who use it frequently, which can easily cause respiratory diseases. Aiming at the above problems, many people try to make some improvements. After searching the existing technical literature, it is found that the process soft blackboard of the patent No. 99248378 uses rollable soft chalk with several double-sided self-adhesive strips attached to the back to write. The soft blackboard is foldable and easy to carry. Because the double-sided adhesive on the back cannot maintain stickiness for a long time, it needs to be replaced frequently, and the wall is required to have high flatness. Therefore, it cannot meet the teaching needs of long-term use of the blackboard; patent number The electric blackboard of 03112751 adopts the roll-type soft blackboard model, and adopts an automatic balancer to avoid the deviation of the blackboard soft panel due to the influence of gravity. It also uses the clutch roller to control the erasing roller brush to realize the two functions of erasing and retaining handwriting , since the character erasing function is completed by a single roller brush, and the character erasing process can only be completed once at a time, it is difficult to ensure that the character writing is wiped clean; and the model of the entire work is a roller type, using a tension brace to adjust The distance between the driving wheel and the driven wheel, however, if the soft panel is always in a tight state, it will affect the service life of the blackboard; moreover, the area of the soft panel is limited, it is difficult to solve the problem of insufficient writing surface in actual use.
