Problems solved by technology

[0002] Although the writing implements on the existing market are complex and changeable in form and complete in variety, they all have the following common shortcomings: 1. The stock of writing ink is too small, and the frequency of changing new pens is very high

2. Due to the structure of the writing instrument itself, if the filling exceeds the capacity that it can bear to store the writing ink, the pen is very easy to leak ink, so its leakage resistance is very poor, so the writing ink in the existing writing instruments The liquid capacity is a low-capacity structure

4. Especially a kind of disposable writing instrument of popular type, often because writing ink fluid is used up fast and whole writing instrument is still very new just has to be discarded, thereby the utilization rate of whole writing instrument is very low, cause a lot of waste of resources

However, it was found that during the forward movement of the nib of this type of marking pen, too much liquid often flowed or penetrated into the nib and could not be sucked back in time, or sometimes the air was sucked back and the writing ink was rarely sucked back.

Furthermore, for the writing instrument with a nib with a ball, because it is closed, the liquid that penetrates or is pressed out can hardly be sucked back, so there is still a dripping phenomenon.
