When in use, the user operates the pumping device relative to the base, which can make the auxiliary extraction structure's active plug move upward relative to the pumping cylinder, that is, the liquid filled in the container's inner cavity can be pumped into the pumping cylinder through the liquid inlet / outlet pipe 211. When the required amount is reached, the pumping device is separated from the base, that is, the liquid inlet / outlet pipe 211 is separated from the container's inner cavity, and then the active plug moves downward relative to the pumping cylinder, which can make the liquid in the pumping cylinder flow out from the liquid inlet / outlet pipe 211. For this reason, the present invention can facilitate the user to take out the liquid from the container's inner cavity, and thus has the characteristics of simple structure, smooth liquid discharge, easy and convenient use, and is convenient for quantitative use.

When in use, the user opens the air intake port by operating the air intake valve, so that a ventilation passage is formed between the air intake port, the inner cavity of the liquid extraction cylinder and the liquid inlet / outlet pipe, so that the liquid filled in the liquid extraction cylinder can flow out from the liquid inlet / outlet pipe. After use, the air intake valve is used to close the air intake port, that is, the liquid extraction cylinder is isolated from the outside world, which has the characteristics of smooth liquid discharge, convenient use and reasonable design.
