<p>PURPOSE: A fluid pumping device is provided to allow a pressing unit to reciprocate in a storage space to automatically send fluid into the fluid pumping device. CONSTITUTION: A fluid pumping device (10) comprises a chamber (100), a fluid discharge unit (200), a pressing unit (400), a fluid supply unit (300), and reciprocating units (500). The fluid discharge unit selectively discharges fluid stored in a storage space (110) of the chamber to the outside. The pressing unit is formed on the top end of the chamber to close the open portion of the storage space. The fluid supply unit selectively supplies fluid to the storage space. The reciprocating units are formed on both sides of the chamber to vertically reciprocate the pressing unit.</p> |
