Abstract
A liquid filling device is provided, including: a barrel, a piston assembly and a force accumulating assembly. The barrel defines an axial direction and includes a liquid storage space and a through hole communicated with the liquid storage space. The piston assembly includes a piston and a push rod connected with the piston, and the piston is axially movable and is disposed in the liquid storage space. The force accumulating assembly is disposed between the barrel and the piston assembly, and when the force accumulating assembly accumulates force, the piston is driven by the force accumulating assembly to move and push a liquid in the liquid storage space. Therefore, the liquid filling device can fill the liquid automatically, which is laborsaving.

A liquid filling device, including:
- a barrel, defining an axial direction, including a liquid storage space and a through hole communicated with the liquid storage space;
- a piston assembly, including a piston and a push rod connected with the piston, the piston being axially movable and disposed in the liquid storage space;
- and
- a force accumulating assembly, disposed between the barrel and the piston assembly, wherein when the force accumulating assembly accumulates force, the piston is driven by the force accumulating assembly to move and push a liquid in the liquid storage space;
- wherein the force accumulating assembly includes two elastic members and at least one connecting member which are sleeved to the push rod, the at least one connecting member is movable relative to the push rod, and the two elastic members are located at two opposite sides of the at least one connecting member and elastically abutted against and between the barrel and the piston.
