The invention provides a water-suction pen core. A piston is arranged in the body of the pen core; the piston is provided with a pull cord which is connected with a pull ring arranged at the tail endof the pen core body; and the front section of the pen core body is screwed with a detachable pen point. When the pen core is used, the built-in piston moves downwards with the decrease of the pen ink; and when the ink runs out, ink can be sucked again for use under the action of the suction force of the piston by simply screwing off the pen point and pulling the pull ring on the tail end.
Description
technical field [0001] The invention relates to a pen core, in particular to a water-absorbing pen core. Background technique [0002] The various pen refills used now are all disposable. After the interior ink is used up, they must be thrown away and replaced with new pen refills, which wastes resources and increases expenses, and causes pollution to the environment. Contents of the invention [0003] The invention provides a water-absorbing pen core, which has the characteristics of repeatedly absorbing ink and using it.
