wherein after the sealing portion ( 463 ) detaches from the block element ( 415 ) for a predetermined distance, the rod head ( 461 ) detaches from a stopper ( 242 ) on the outlet check valve ( 140 ) to render an output terminal of the outlet check valve ( 140 ) to become a close status.

2. The dual-mode fluid connector ( 150 ) of claim 1 , further comprising:
a rotatable element ( 380 ), covered on the rear portion ( 340 ) and engaged with the rod ( 360 ), and arranged to operably drive the rod ( 360 ) to move forward or backward.

3. The dual-mode fluid connector ( 150 ) of claim 2 , wherein a track ( 443 ) is arranged on an outer surface of the rear portion ( 340 ), the rod ( 360 ) comprises an outer flange ( 467 ), the rotatable element ( 380 ) comprises a guiding element ( 487 ) and a block portion ( 489 ), the guiding element ( 487 ) is positioned in an interior of the rotatable element ( 380 ) and arranged to operably engage with the track ( 443 ), and the block portion ( 489 ) is positioned in the interior of the rotatable element ( 380 ) and arranged to operably engage with the outer flange ( 467 );
wherein the guiding element ( 487 ) is arranged to operably move along the track ( 443 ), and the block portion ( 489 ) is arranged to operably drive the rod ( 360 ) to move forward or backward together with the rotatable element ( 380 ).

4. The dual-mode fluid connector ( 150 ) of claim 3 , wherein when the rotatable element ( 380 ) is rotated toward a first predetermined direction, the rotatable element ( 380 ) moves forward while rotating and drives the rod ( 360 ) to move forward until the sealing portion ( 463 ) abuts the block element ( 415 );
wherein when the sealing portion ( 463 ) abuts the block element ( 415 ), the first space ( 412 ) and the second space ( 413 ) are separated by the sealing portion ( 463 ) and the block element ( 415 ) so that the first space ( 412 ) and the second space ( 413 ) are isolated with each other, and the rod head ( 461 ) pushes the stopper ( 242 ) inward to render the output terminal of the outlet check valve ( 140 ) to become an open status.

5. The dual-mode fluid connector ( 150 ) of claim 4 , wherein after the sealing portion ( 463 ) abuts the block element ( 415 ), if the rotatable element ( 380 ) is rotated toward a second predetermined direction, then the rotatable element ( 380 ) moves backward while rotating and drives the rod ( 360 ) to move backward together, so that the sealing portion ( 463 ) detaches from the block element ( 415 ).

6. The dual-mode fluid connector ( 150 ) of claim 5 , wherein an outer surface of the rotatable element ( 380 ) comprises a first area ( 581 ) and a second area ( 582 ), the dual-mode fluid connector ( 150 ) operates in a serve mode when the rotatable element ( 380 ) is rotated to a status where the first area ( 581 ) faces upward, and the dual-mode fluid connector ( 150 ) operates in a clean mode when the rotatable element ( 380 ) is rotated to a status where the second area ( 582 ) faces upward.

7. The dual-mode fluid connector ( 150 ) of claim 5 , further comprising:
a bended plate ( 370 ), positioned between the rotatable element ( 380 ) and the rear portion ( 340 ), and an outer surface of the bended plate ( 370 ) comprises a first marked region ( 471 ) and a second marked region ( 473 );
