Abstract
The present invention discloses a direct writing pen and its components. The direct writing pen component is a direct writing pen barrel, a direct writing pen connector or a direct writing pen tip. The ink channel formed by the inner wall of the direct writing pen component has at least one variable diameter portion; at least one of the variable diameter portions has a flow guide structure for destroying the surface tension of the ink at its center. The present invention uses a flow guide structure for destroying the surface tension of the ink at a variable diameter position in the ink channel, destroys the original surface structure of the ink, avoids the blockage of the ink at a narrow opening, and ensures smooth delivery of the ink.
