Abstract: A liquid transfer apparatus comprises an output terminal device, a receiving terminal device, a connecting pipeline, and a control device. The output terminal device includes a first pressurizing member for filling the first storage container with high-pressure air. The receiving terminal device includes an air pressure adjusting member for adjusting the air pressure inside the second storage container. When the liquid transfer apparatus is in a non-transferring state, the air pressure inside the second storage container is high enough to prevent the liquid in the first storage container flow into the connecting pipeline. And when the liquid transfer apparatus is in a transferring state, the pressure difference between the inside of the first storage container and the inside of the second storage container is sufficient to drive the liquid in the first storage container to enter the second storage container.
