[0050] Working principle: The temperature in the cavity formed by the top of the heat insulation board 22 and the heat insulation board 21 is kept constant through the heat insulation cover 21 and the heat insulation board 22. When the temperature in the furnace body 1 rises, the air will expand due to the heat, thereby pushing up the heat insulation board 22. When the top column 23 contacts the primary contact switch 24, the primary contact switch 24 transmits a signal to the external terminal, which receives the signal and controls the electromagnetic valve 512 to open, so as to discharge the gas in the furnace body 1 to prevent the furnace body 1 from having a high pressure and causing danger. When a certain amount of gas is discharged and the heat insulation board 22 is lowered, the top column 23 is separated from the primary contact switch 24, and the primary contact switch 24 transmits a signal to the external terminal, which receives the signal and controls the electromagnetic valve 512 to close, so as to prevent the furnace body 1 from having a high pressure and causing danger.

[0051] The heat insulation cover 21 cooperates with the sliding plate 34 and the secondary contact switch 32 to monitor the wind force of the fan 510. That is, when the wind force introduced by the fan 510 is large, the heat insulation cover 21 will be lifted to a higher height, driving the sliding plate 34 to rise. When the sliding plate 34 rises to contact with the secondary contact switch 32 located above, the secondary contact switch 32 transmits a signal to the external terminal. The external terminal receives the signal and controls the fan 510 to reduce its power until the sliding plate 34 contacts with the secondary contact switch 32 located in the middle. The secondary contact switch 32 located in the middle transmits a signal to the external terminal. The external terminal controls the fan 510 to stop reducing its power to prevent the high wind force of the hot air circulation from causing heat separation. The uneven distribution affects the baking quality. When the wind force introduced by the fan 510 is small, the heat insulation cover 21 and the sliding plate 34 descend. When the sliding plate 34 contacts the secondary contact switch 32 located below, it indicates that the wind force is insufficient. At this time, the secondary contact switch 32 located below transmits a signal to the external terminal. The external terminal receives the signal and controls the fan 510 to increase the power, thereby increasing the lifting height of the heat insulation cover 21. When the sliding plate 34 contacts the secondary contact switch 32 located in the middle as the heat insulation cover 21 rises, the secondary contact switch 32 located in the middle transmits a signal to the external terminal. The external terminal receives the signal and controls the fan 510 to stop increasing the power, thereby preventing the baking time from being prolonged due to the small wind force.
