Background

The marking pen is a pen capable of writing or marking on one or more materials such as paper, white board, wood, metal, plastic, ceramic and the like, and is also called a mark pen. Depending on the ink used, the ink is classified into an oil-based marker and a water-based marker. The marker pen used for writing on the whiteboard is often called as a whiteboard marker pen, and is called as a whiteboard marker pen for short, is easy to erase after writing, and is widely applied to office and teaching activities. However, when the existing marking pen writes at a certain elevation angle, the ink is not continuously discharged and the writing is not smooth after a short period of time. This is determined by the inherent structure of existing markers because: in the state of the pen point with the upward elevation angle, as shown in figure 1, the ink is positioned at the lower part of the ink bag and is not contacted with the pen point, the ink remained in the pen point is consumed during writing, and the pen point is dried up after a while. Therefore, the structural design of the marking pen needs to be changed to keep the pen head continuously discharging ink in various writing states and ensure smooth writing.
