Abstract

The invention discloses a water-based pen. The water-based pen includes an ink reservoir, a pen point and a water container assembly, wherein the water container assembly includes a pen item and a water container set inside the pen item. The two water containers are The ends are respectively connected to the ink reservoir and the nib; the water container includes a water delivery channel, an air inlet groove and a side channel, wherein the side channel communicates with the water delivery channel, the air inlet groove and the ink reservoir; By improving the structure of the water tank, the water-based pen can improve the smoothness and tightness of the water outlet of the water-based pen, thereby reducing the waste of ink and improving the drying resistance of the ink.

Description

technical field [0001] The invention relates to the technical field of writing utensils, in particular to a water-based pen. Background technique [0002] Existing straight liquid pens all adopt the sealing method of nesting a pen item outside the water container, and the cooperation state of the water container and the pen item determines the smoothness and uniformity of the ink output. If the cooperation between the water container and the pen item is too tight, it is easy to cause poor writing ink; if the gap between the water container and the pen item is too large, it is easy to cause ink leakage, resulting in ink waste. Especially when the external air pressure changes greatly, the phenomenon of ink leakage is unavoidable. [0003] When the water-based pen adopts erasable ink, due to the high cost of the erasable ink, ink leakage will cause great waste. [0004] Therefore, it is urgent to provide a water-based pen with better airtightness and stability to solve the a...
