Fluid material dispensing apparatus capable of maintaining fluid material within material transmission path at low temperature

A fluid material dispensing apparatus (100), comprising:

• a material outlet chamber (105), wherein a side wall of the material outlet chamber (105) is provided with a pipe insertion port (360) and a reflow port (370);
• multiple pumps (110), arranged to respectively extract multiple fluid materials stored in multiple material containers (180), and to operably push corresponding fluid materials forward;
• a fluid output device (140), positioned on a bottom portion of the material outlet chamber (105), and comprising multiple fluid outlets (142), wherein the multiple fluid outlets (142) are respectively coupled with the multiple pumps (110) through multiple material transmission paths, and are respectively arranged to dispense corresponding fluid materials to a target container (190);
• a temperature sensor (255), positioned in the material outlet chamber (105), arranged to operably sense an internal temperature of the material outlet chamber (105);
• a cold air tunnel (220), arranged to operably introduce cold air into the material outlet chamber (105), so as to maintain the internal temperature of the material outlet chamber (105) below a predetermined temperature, wherein the cold air tunnel (220) comprises:
• an air intake duct (221), coupled with a cold air source device (210) and having an air inlet (227), arranged to operably receive cold air generated by the cold air source device (210);
• an intermediate duct (223), coupled with the air intake duct (221);
• and
• an air output duct (225), coupled with the intermediate duct (223) and having an air outlet (229), arranged to operably output cold air into the material outlet chamber (105);
• and
• one or more air extraction devices (231;
• 233;
• 235), positioned on an airflow transmission path of the cold air tunnel (220), arranged to operably push cold air in the cold air tunnel (220) forward, wherein the one or more air extraction devices (231;
• 233;
• 235) comprises:
• a first air extraction device (231), positioned at the air inlet (227), arranged to operably extract a part of cold air generated by the cold air source device (210) into the air intake duct (221);
• a second air extraction device (233), positioned between the air intake duct (221) and the intermediate duct (223), arranged to operably push cold air within the air intake duct (221) into the intermediate duct (223);
• and
• a third air extraction device (235), positioned near a junction between the intermediate duct (223) and the air output duct (225), arranged to operably extract a part of cold air within the cold air tunnel (220) into an upper chamber (101) of the fluid material dispensing apparatus (100);
• wherein multiple material transmission pipes coupled between the multiple pumps (110) and the fluid output device (140) pass through the pipe insertion port (360) and enter the material outlet chamber (105);
• wherein cold air in the material outlet chamber (105) flows into the main body of the fluid material dispensing apparatus (100) through the reflow port (370).
