Beschreibung
Zusammenfassung:	The utility model belongs to an air pressure water suction device used for sucking ink. The air pressure water suction device is mainly composed of an air cylinder, a piston, a one-way valve, etc. A central axis penetrating through the piston is provided with a pen cap shape cavity. When the air pressure water suction device is used, a penpoint is inserted in the cavity tp moves up and down, and the ink can be sucked. The utility model has the advantages that when the air pressure water suction device can be used, without removing the loop bar of a pen, and the ink can be directly sucked. The complicated operating procedure for sucking the ink for the existing pen is simplified. The utility model has the advantages of compact structure, simple structure, reliable use and easy fabrication. The air pressure water suction device can be used for holding fluid for other paucity containers with small calibers. Nothing remains but to change the shape of the cavity.
