Description

A straight liquid writing pen

Technical field:

The utility model relates to a straight liquid writing pen.

Background technique:

Most of the writing pens commonly used at present are disposable, and are discarded directly after use. The service life is low, which causes certain waste and also causes certain pollution to the environment. Although non-disposable pressure-injection writing pens have also appeared on the market, as the pens are used, the amount of ink stored in the nib will gradually decrease, causing the writing color to become lighter, and the writing color depth is uneven, which affects the writing effect. When the writing color becomes lighter, the teacher needs to press the nib to make the ink flow to the nib, which will interrupt the teacher's train of thought and affect the quality of teaching. In addition, this writing pen has a complex structure and high manufacturing costs, making it difficult to be popularized and used on a large scale.
