At this time, turn the air compressor control knob 22 to start the air compressor 35, which exhausts air from the furnace body 3 through the vacuum tube 15. The pressure inside the furnace body 3 can be visually viewed through the pressure display screen 20, allowing the operator to stop the air compressor at any time. 35.

[0030] As can be seen from the above working process: This utility uses the cooling pipe to rotate the inlet pump control knob 23 and the outlet pump control knob 24, which starts the inlet pump 38 and the outlet pump 39. This allows the cooling water in the cold water tank 30 to enter the cooling pipe 13 through the inlet pipe 16 and then flow back to the cold water tank 30 through the outlet pipe 17 for neutralization. This allows the cooling water in the cooling pipe 13 to quickly conduct heat to the furnace body 3 during the circulation process, thereby improving the cooling rate of the device.
