Kind Code:
A1
Abstract:
A liquid guiding element and a liquid pen having the element. The liquid guiding element comprises a liquid guiding sleeve (1) and a liquid guiding member (2), the liquid guiding member (2) is inserted into the liquid guiding sleeve (1). A plurality of groups of inner capillary slits (12) is distributed on the inner wall of the liquid guiding sleeve (1), and a sleeve hole (13) is provided at the location of the closed end of each inner capillary slits (12) on the inner wall of the liquid guiding sleeve (1). Since the inner capillary slits (12) have a certain capillary force, the liquid can be more easily guided from one end of the liquid guiding sleeve (1) to the other end, and the capillary slits (12) can also mitigate filtration and blockages in the liquid, so large particles in the liquid can be more stably and reliably presented. The sleeve hole (13) can prevent leaks, and guide and fix the liquid guiding member (2). The liquid pen includes the liquid guiding element and a liquid storage part (3).
