摘要

A liquid storage device. More specifically, the present invention relates to the liquid storage device having a storage amount display function, comprising a housing (1); a folding bag (2) and a rotating shaft (3) are arranged in the housing (1), the rotating shaft (3) is fixed to the housing (1), one end thereof is exposed out of the housing (1), and the end part, which is exposed out of the housing (1), of the rotating shaft (3) is fixedly provided with a pointer (4); and one end of the folding bag (2)is provided with a bag opening (201) which is exposed out of the housing (1), and the other end is fixed to the rotating shaft (3), thereby enabling stretching or contracting of the folding bag (2) to drive the rotating shaft (3) to rotate. The liquid storage device can conveniently observe the storage amount of liquid in a folding bag through a position pointed by a pointer outside a housing, and is very convenient during use; and the liquid storage device is ingenious in structure, easy to manufacture and durable, and is particularly suitable for outgoing, army marching and the like for use.
