1. A fluid material dispensing apparatus (100) for outputting fluid material stored in multiple material containers (130) and capable of conducting an automatic self-disinfection operation, the fluid material dispensing apparatus (100) comprising:
an outlet connector (110);
a fluid connector (150), connected to a target material container (130) of the multiple material containers (130), and comprising a material tube (322) and a cleaning tube (324);
a material transmission pipe (152), coupled between the material tube (322) and the outlet connector (110);
a detergent transmission pipe (154), coupled with the cleaning tube (324);
a pump (160), coupled between the material transmission pipe (152) and the outlet connector (110); and
a fluid diverter (190), comprising a liquid input terminal and multiple liquid output terminals, wherein a target output terminal of the multiple liquid output terminals is coupled with the detergent transmission pipe (154);
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
utilizing operation of the pump (160) to form a negative pressure in the detergent transmission pipe (152), so that the disinfectant solution in the fluid diverter (190) is sucked into the fluid connector (150) through the detergent transmission pipe (154) and the cleaning tube (324), and then flows into the material transmission pipe (152) through the material tube (322) of the fluid connector (150).
