[0002] Watercolor pen, a kind of painting tool. Watercolor pen is a common painting tool for children. The material of the pen head is generally carbon fiber. It is generally sold in boxes of 12 colors, 24 colors, and 36 colors. The pen head is generally round, and the two colors are not easy to blend together. It is generally suitable for children's paintings and can also be used as a marker. The advantages of colored water pens are rich and bright colors. The disadvantages are that they can be used for a short time, the water content is uneven, the transition is unnatural, and the two colors are not easy to blend together, so they are generally suitable for children's paintings. Some colored water pen shells can also be divided into several vertical watercolor grooves. Different watercolors are added to each groove, so that the colored water pen can write different colors of calligraphy and painting characters or different patterns at one time, and the color can be adjusted arbitrarily. A pen can write large characters or large areas of calligraphy and painting at one time, and the color changes are rich, which is more suitable for the creation of calligraphy and painting, improves the painting effect, and is conducive to improving students' learning interest and calligraphy and painting level. In actual production, a groove is usually opened at the bottom of the watercolor pen shell, and the groove is plugged into the convex block to fix the watercolor pen shell.

[0003] At present, the filling of watercolor pen ink is mostly carried out through an assembly line, and the ink is injected into the core tube of the watercolor pen through a material guide nozzle.
