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 target air extraction device (337), a pipe insertion port (360), and a reflow port (370);
• an upper chamber (101), arranged to operably connect to the material outlet chamber (105);
• 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;
• and
• multiple 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 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 a main body of the fluid material dispensing apparatus (100) through the reflow port (370);
• wherein the target air extraction device (337) is arranged to operably extract a part of cold air in the material outlet chamber (105) into the upper chamber (101).
