Pressure supply module and liquid supply system having the same

Abstract

A liquid supply system includes a base seat, a liquid storage apparatus, and a pressure supply module. The liquid storage apparatus is disposed on the base seat, and has liquid tanks for containing liquids, each having an entrance and an exit that is used for liquids to flow out. The pressure supply module includes a connection unit having a connection member and first flow valves, and an actuation unit. The connection member has an air intake opening and air outlet openings connected to the air intake opening. The air outlet openings respectively connect the entrances of the liquid tanks. The first flow valves are respectively disposed on the air outlet openings. The actuation unit is disposed on the base seat and connects the air intake opening. The actuation unit is for providing air at constant pressure to the air intake opening.
