Abstract
A system for managing liquid supply is provided. The system includes an air pressure adjustor, a first liquid container, a second liquid container, a first tube, a second tube, an inlet sensor, and an outlet sensor. The first liquid container includes a liquid. The second liquid container includes an inlet and an outlet. The first tube is configured to be connected between the first liquid container and the inlet. The second tube is configured to be connected between the outlet and the air pressure adjustor. The inlet sensor is disposed on the first tube and for detecting the liquid flowing into the inlet. The outlet sensor is disposed on the second tube and for detecting the liquid flowing out from the outlet.
Claims13
A system for managing liquid supply, the system comprising:
- an air pressure adjustor;
- a first liquid container comprising a liquid;
- a second liquid container comprising a drain, an inlet and an outlet;
- a first tube connected between the first liquid container and the inlet;
- a second tube connected between the outlet and the air pressure adjustor;
- an inlet sensor disposed on the first tube and for detecting the liquid flowing into the inlet;
- an outlet sensor disposed on the second tube and for detecting the liquid flowing out from the outlet;
- an outlet valve disposed between the outlet sensor and the air pressure adjustor;
- a drain tube connected to the drain;
- a drain valve disposed on the drain tube;
- and
- a control unit coupled to the inlet sensor, the outlet sensor, the outlet valve, the drain valve, and the air pressure adjustor, the control unit configured to:
- retrieve data from the inlet sensor and the outlet sensor;
- and
- perform an operation comprising closing the drain valve and opening the outlet valve when the inlet sensor detects that the first liquid container is empty.
A method for managing liquid supply from a first liquid container to a second liquid container, the method comprising:
- providing a system for managing liquid supply, the system comprising:
- a first liquid container comprising a liquid;
- a second liquid container comprising a drain, an inlet and an outlet;
- a first tube connected between the first liquid container and the inlet;
- a second tube connected between the outlet and the air pressure adjustor;
- an inlet sensor disposed on the first tube and for detecting the liquid flowing into the inlet;
- an outlet sensor disposed on the second tube and for detecting the liquid flowing out from the outlet;
- an outlet valve disposed between the outlet sensor and the air pressure adjustor;
- a drain tube connected to the drain;
- a drain valve disposed on the drain tube;
- in response to a first signal from the inlet sensor for indicating an absence of the liquid in a predetermined portion of the first tube, closing the drain valve and opening the outlet valve;
- and
- switching on the air pressure adjustor to create a vacuum in the second liquid container, the first tube, and the second tube.
