Abstract

A pen which is convenient for infusing ink comprises a penholder (1), a pen cap (2) and a pen tube (3). The opening ends of the pen cap and the penholder are respectively connected with pen tube screw threads. The pen is characterized in that the pen tube (3) and a pen head (4) are designed as demountable type seal connection structures; the inside of the upper opening end of the pen tube (3) is provided with the piston (6) with a push-pull rod (7); the lower seal end of the pen tube (3) is provided with a tubule (8), the outer circle of which is in seal connection with the lower seal end of the pen tube (3); the upper end of the tubule (8) is communicated with the inner cavity of the pen tube (3), and the lower end is communicated with the inner cavity of the pen head (4). When ink is infused, the penholder is taken off, the pen tube and the pen head are separated, then the tubule at the pen tube is put into an ink bottle, the injector theory is used, and the push-pull rod at the tail end of the pen tube is used for pulling the piston to suck the ink. The utility model is convenient and clean for using and can also be applied to infuse the sticky ink into an oil pen and a whiteboard pen.

Description

Make things convenient for the pen of ink injection

Technical field

The utility model relates to writing implement, especially a kind of pen that makes things convenient for ink injection.

Background technology

Marking pen now commonly used or blank pen and fountain pen are very practical because of it, also make things convenient for marking and very popular.But the each water filling of existing fountain pen all can make pen head part be full of ink, is bonded on hand again, and oil pen's ink generally all compares thickness in addition, directly suck and have any problem, because it can't exchange an inner core for, after its ink uses up from nib, have to abandon, waste very serious; Still finding no a kind of easy method up to now can address this problem.

Summary of the invention
