Problems solved by technology

[0002] Whiteboard markers are indispensable larger utensils in teaching, and are also office supplies commonly used in offices. Existing whiteboard markers mainly adopt ink-absorbing fibers to store ink in structure. This mode mainly has the following deficiencies: one is to store ink The capacity is limited. Second, the ink supply efficiency is low. In the continuous writing process, the ink often breaks and the writing is not smooth. The third is that the ink cannot be added, because when the ink is used up, the nib will dry and the ink will break. It is also difficult to restore the ink absorption ability of the ink
Therefore, in daily use, you need to stop for a while and wait for the ink supply to continue to use. To verify whether the ink is supplied, many users will use a pen to draw random lines on the whiteboard, and continue to use it after they can draw continuous and clear lines. Affect work efficiency and the user's thinking, but also affect the user's emotions

Abstract

The invention discloses a pen provided with an ink transmission tube. The pen mainly comprises a pen holder, a pen cap, a pen cartridge and ink, wherein the pen holder is hollow; the ink is stored in an inner hole of the pen holder; one end of the pen holder shrinks to form a pen point, and the other end of the pen holder is connected with the pen cap. A piston is adopted to provide ink for an ink storage cavity to improve the ink providing condition and reduce the ink shortage phenomenon so as to enable writing to be smoother; ink can be added for a plurality of times to prolong the service life of a whiteboard marker.
