5. The anti-scald electric control system for the vending machine as claimed in claim 1, wherein the temperature control module controls the spray head to enter the working state when receiving overheating information of the brewing head region, and controls the spray head to spray when the infrared sensor detects that an object is approaching within the range of LI, so as to remind a user of scalding. The temperature control module controls the small fan to start simultaneously, blows air to the brewing head area for heat dissipation, stops the small fan to rotate when the temperature control module cannot accept overheating information in the area, judges that the brewing head area has fan heat dissipation faults when T1 is greater than Q1, and prompts heat dissipation fault information of the brewing head area of a user on the control panel.
6. The anti-scald electric control system for the vending machine as claimed in claim 5, wherein the temperature control module controls the voice speaker to send out a voice alarm when receiving the early warning information of the brewing head region, so as to prompt the region to exceed a preset temperature range, and control to cut off the power supply of the vending machine, thereby realizing emergency stop.
7. The anti-scald electric control system for the vending machine as claimed in claim 5, wherein the temperature control module controls the detection ring to start when receiving the overheating information of the heating box area, the detection ring detects whether the lower end of the brewing head is provided with the cup, if the cup is not provided, the brewing head is locked to prevent the hot coffee from flowing out, the user is prevented from being scalded, the small fan in the heating box area is controlled to start, the temperature control module controls the small fan to start simultaneously to blow and dissipate heat of the brewing head area, when the temperature control module cannot receive the overheating information of the area, the small fan is stopped to rotate, when T2 is greater than Q2, the fan cooling fault in the area is determined, and the user is prompted on the control panel about the cooling fault information of the heating box area.
8. The anti-scald electric control system for the vending machine as claimed in claim 5, wherein the temperature control module controls the voice speaker to send out a voice alarm when receiving the early warning information of the heating box area, so as to prompt the area to exceed a preset temperature range, and control to cut off the power supply of the vending machine, thereby realizing emergency stop.
9. The anti-scald electric control system for the vending machine as claimed in claim 5, wherein the temperature control module, when receiving the overheating information of the water pump area, directly judges that the area is in failure, and controls the power supply to be cut off, so that the vending machine is emergently stopped.
10. The anti-scald electric control system for the vending machine as claimed in claim 5, wherein the temperature control module, when receiving the overheating information of the water tank area, directly judges that the area is in failure, and controls the power supply to be cut off, so that the vending machine is emergently stopped.
