after the cleaning procedure is conducted for the predetermined length of time, controlling the pump ( 160 ) to continue to operate to cause the cleaning solution in the material transmission pipe ( 152 ) to be discharged through the outlet connector ( 110 ).

6. The fluid material dispensing apparatus ( 100 ) of claim 2 , further comprising:

a valve ( 194 ), coupled between the target output terminal of the fluid diverter ( 190 ) and the detergent transmission pipe ( 154 ), and utilized to prevent fluid in the detergent transmission pipe ( 154 ) from flowing back into the fluid diverter ( 190 ).

7. The fluid material dispensing apparatus ( 100 ) of claim 2 , wherein the fluid material dispensing apparatus ( 100 ) further conducts an automatic self-disinfection operation after the automatic self-cleaning operation is complete;

wherein the automatic self-disinfection operation comprises:

guiding a disinfectant solution to flow into the fluid diverter ( 190 );

activating the pump ( 160 ) to push residual cleaning solution in the material transmission pipe ( 152 ) forward, so that the residual cleaning solution is discharged through the outlet connector ( 110 ); and

guiding that the disinfectant solution in the fluid diverter ( 190 ) to flow into the fluid connector ( 150 ) through the detergent transmission pipe ( 154 ), and then flows into the material transmission pipe ( 152 ) through the material tube ( 322 ) of the fluid connector ( 150 ).

8. The fluid material dispensing apparatus ( 100 ) of claim 7 , wherein the automatic self-disinfection operation further comprises:

controlling the pump ( 160 ) to continue to operate for a period of time, so that the residual cleaning solution in the material transmission pipe ( 152 ) and a part of the disinfectant solution are discharged through the outlet connector ( 110 ).

9. The fluid material dispensing apparatus ( 100 ) of claim 8 , wherein the automatic self-disinfection operation further comprises:

activating the pump ( 160 ) to push the disinfectant solution in the material transmission pipe ( 152 ) forward, so that the disinfectant solution in the material transmission pipe ( 152 ) is discharged through the outlet connector ( 110 ).
