Pen automatic water aspirator

Abstract

The invention relates to a novel stationery which can realize automatic water absorption by the common pen and is characterized in that the negative pressure in a pen bag and the positive pressure in an ink bottle can be realized by adopting the piston type structure. The invention has the advantages that the stationery has simple structure and the automatic water absorption of the pen can be realized without changing the structure of the existing pen and the ink bottle, thus leading the process of water absorption of the pen to be more convenient and cleaner.

Description

technical field [0001] The invention relates to an automatic water absorber for a pen, which belongs to stationery. Background technique [0002] At present, ordinary pens cannot absorb water automatically. When absorbing water, it is necessary to unscrew the pen body and manually squeeze the water storage bag to complete the water absorption, which is inconvenient. Contents of the invention [0003] In order to overcome the shortcoming that ordinary fountain pens cannot automatically absorb water, the invention provides a new type of stationery that can enable ordinary fountain pens to automatically absorb water. [0004] The technical solution adopted by the present invention to solve the technical problem is: to simulate the exhaust and suction strokes of the internal combustion engine, and when the pen pushes the piston down, the pen bag will form a negative pressure, and at the same time, the air pressure in the pen water bottle will increase, and the piston will move...
