Mixing apparatus

A mixing apparatus, comprising:

• a driving device, a first transfer chamber, and a second transfer chamber, wherein the driving device is configured to drive a first liquid to flow into the first transfer chamber through a liquid inlet of the first transfer chamber, the first transfer chamber is configured to store inflowed first liquid, the driving device is further configured to drive a second liquid to flow into the second transfer chamber through a liquid inlet of the second transfer chamber, and the second transfer chamber is configured to store inflowed second liquid;
• a premixing chamber communicating with a liquid outlet of the first transfer chamber and a liquid outlet of the second transfer chamber, wherein the first liquid and the second liquid are mixed in the premixing chamber to generate a premixed liquid;
• and
• a monitor, configured to monitor a volume of the first liquid in the first transfer chamber and a volume of the second liquid in the second transfer chamber, to close the liquid inlet of the first transfer chamber and control the first liquid in the first transfer chamber to flow into the premixing chamber when the volume of the first liquid is equal to a first value, and to close the liquid inlet of the second transfer chamber and control the second liquid in the second transfer chamber to flow into the premixing chamber when the volume of the second liquid is equal to a second value.
