AI Technical Summary

Problems solved by technology

However, during the use of the above-mentioned cotton ball pen, the cotton ball needs to be pushed out from the pen holder by a spring. If the force is large, it is easy to push out a plurality of cotton balls from the pen holder together, thereby causing waste of cotton balls.

Moreover, since the cotton ball is covered with a layer of protective film, it needs to be punctured with a needle during use, and the protective film cannot be automatically punctured, so the operation is more complicated

In addition, since the needles are exposed to the outside world, the needles are easily polluted. When the needles pierce the protective film, the needles are easy to contaminate the cotton balls, which affects the normal use of the cotton balls.
