Straight liquid type writing item component and pen with the same

Abstract

The present invention provides a liquid writing component and pen equipped with the component which relates to writing tool; a liquid writing component comprises a pen stem, a pen head, an ink cavity and a water diversion part equipped between the pen head and the ink cavity; the pen stem internal and external circles are equipped with a plurality of circular grooves; the bottom surfaces of the circular grooves are equipped with water storing devices and the central parts of the pen stem and the water storing devices are equipped with central holes through with the water diversion part can be penetrated; a valve channel communicated with the ink cavity is equipped between the external surface of the water diversion part and the internal surface of the central holes; the circular groove bottom surface of the water storing devices is equipped with nicks communicated with the central holes; the water storing device of the component boasts of simple structure and low cost; the valve channel clearance can meet the matching requirements of various pen head and the ink cavity internal pressure; in this way, the present invention boasts of wide application fields, smooth ink delivery and excellent leakage resistant function; the ink bag structure reduces the writing cost; the component has the features of common utilization and interchangeable technology and can be purchased independently and alternatively used repeatedly. Therefore, the component is fit for liquid pen and liquid pen refill.

Description

technical field [0001] The present invention relates to writing implements, in particular to a direct-liquid writing item assembly and a pen with the direct-liquid item assembly, and the pen includes a direct-liquid pen core. Background technique [0002] At present, the commonly used rollerball pens, disposable fountain pens and colored ink pens, microporous ink pens, fluorescent ink pens, whiteboard pens, straight liquid refills, etc. are all made of plastic bodies. The water diversion part of the pores leads the ink to the tip of the pen for writing. There are only two types of ink storage structures. One is the roll-wrapped core structure. This structure has low technical requirements and is simple. It has been widely used by manufacturers. The disadvantage is that the ink storage cannot be fully used. The loss of ink is large, the handwriting becomes lighter with the reduction of ink, the cost of writing is high, and the ink is not easy to feel; the other is to use a wa...

AI Technical Summary

Problems solved by technology

[0004] The above scheme has major disadvantages: 1. The structure is relatively complex, the precision requirements are high, the processing is difficult, and the production cost is high. The thin straight groove on the outer periphery of the water storage device runs through the ring groove longitudinally, reducing the strength of the ring groove cavity of the mold. Shorten the service life of the mold; 2. The shape and size of the air valve channel located at the axial front end of the thin straight groove on the outer periphery of the water reservoir are embossed by the inserts on the corresponding positions of the forming mold. Its size is fixed and the applicable surface is single. It is difficult to match with the internal pressure balance of the ink chamber, the matching period is long, and the cost is high; and due to the limitation of the strength of the insert and other factors, the gap size of the embossed valve channel is limited, and it is difficult to meet the direct liquid pen with a plastic body. 3. Poor versatility, it is difficult to refill the ink after the ink is used up. It is basically a disposable pen. Discard the still intact pen holder with the ink exhausted or the nib worn out. Causes a waste of sustainable resources, and the economy is not high
