Direct liquid type refill capable of being used for pressing writing pen

Abstract

The invention discloses a direct liquid type refill capable of being used for a pressing writing pen, which comprises a refill assembly, a pen point arranged at one end of the refill assembly and a water leading refill with elastic deformation capability, and an ink flowing channel and a ball component positioned at the tail end of the ink flowing channel are arranged in the pen point. The ink guiding core is arranged in the pen refill assembly in a penetrating mode, one end of the ink guiding core extends into the ink flowing channel and abuts against the ball bead component, so that the ink guiding core is compressed to generate elastic deformation, and elastic force is applied to the ball bead component to enable the ball bead component to abut against the inner wall of the tail end of the ink flowing channel tightly. According to the direct liquid type pen refill capable of being used for the pressing writing pen, the water leading refill with the elastic deformation capacity is adopted, the ball component is driven to abut against the inner wall of the pen point bowl opening on the pen point under the elastic force effect of the water leading refill to achieve self-sealing, ink leakage and ink drying are prevented when writing is not carried out, and the direct liquid type pen refill can be suitable for various types of writing pens such as the pressing type writing pen.

Description

technical field [0001] The invention relates to the technical field of writing pens, in particular to a straight-liquid refill which can be used to push the writing pen. Background technique [0002] Compared with traditional writing pens, direct-liquid rolling ball writing pens have the advantages of uniform ink application, smooth writing, and long writing length, so they are becoming more and more popular among consumers. Its principle is to provide ink directly through the ink storage chamber provided by itself, and install a water guide core in the pen, the ink is adsorbed on the water guide core and is continuously transported to the pen tip through the water guide core and the nib. Because the ink used in the direct liquid writing refill is easy to volatilize and dry up, the existing technology adopts the structure design of installing a cap on the pen, and inserts the cap on the pen tip to seal it when not in use, making the direct liquid refill unusable On the push...
