1. A dual-mode fluid connector (150), comprising:
a hollow connecting element (310), comprising a chamber (411) inside the hollow connecting element (310), wherein a protuberant block element (415) is arranged on an inner surface of the chamber (411), and the block element (415) divides an interior space of the chamber (411) into a first space (412) and a second space (413);
a material tube (322), positioned on the hollow connecting element (310) and connected through the chamber (411);
a cleaning tube (324), positioned on the hollow connecting element (310) and connected through the chamber (411);
a head portion (330), positioned on one terminal of the hollow connecting element (310) and comprising a connecting opening (431), wherein the connecting opening (431) is connected through the chamber (411) and capable of being detachably connected to an outlet check valve (140) on a material container (130);
a rear portion (340), positioned on another terminal of the hollow connecting element (310) and comprising a through hole (441); and
a rod (360), inserted into the chamber (411) via the through hole (441) and comprising a rod head (461) and a sealing portion (463);
wherein when the connecting opening (431) is detachably connected to the outlet check valve (140) to cause the sealing portion (463) to abut the block element (415), the rod head (461) pushes a stopper (242) on the outlet check valve (140) inward to render an output terminal of the outlet check valve (140) to become an open status.
