7. The method for using the automatic ignition furnace according to any one of claims 1 to 6, characterized in that: The following steps are involved: A: Place a proper amount of charcoal on the top of the inner cavity bottom plate (28) of the furnace body (32), place some newspapers through the square hole at the bottom of the bottom plate (28), light the newspapers, and the burning of the newspapers ignites the charcoal. After a certain period of burning, the temperature of the inner cavity of the furnace body (32) rises, and the gas pressure in the inner cavity of the glass jar (10) increases and expands due to the heat. The gas pressure in the inner cavity of the glass jar (10) pushes the hot gas piston (11) to move to the left, and the hot gas piston (11) pushes the piston connecting rod (9) and the hot cylinder seat ( 13) moves to the left, the hot cylinder seat (13) pushes the connecting rod (2) to move to the left, the connecting rod (2) pushes the flywheel (21) to rotate through the second positioning pin (20), the flywheel (21) drives the second fixed shaft (22) to rotate, the second fixed shaft (22) drives the transmission wheel (1) to rotate, the transmission wheel (1) drives the connecting rod (2) to move through the second positioning pin (20), the connecting rod (2) drives the cold air piston (5) to move, and the cold air piston (5) moves in the inner cavity of the cold air cylinder body (6); B: The flywheel (21) further drives the fan blade seat (16) to rotate through the transmission belt (19), and the fan blade seat (16) drives the fan blade (15) to rotate. The fan blade (15) rotates to move the air flow upward, blowing air to the charcoal, so that the charcoal burns quickly. After the flywheel (21) rotates half a circle, it drives the connecting rod (2) to move rightward, and the connecting rod (2) drives the hot cylinder seat (13), the rubber ring (12) and the hot gas piston (11) to move rightward. The piston moves rightward to compress the gas in the inner cavity of the glass jar (10) again, and the gas in the inner cavity of the glass jar (10) expands and pushes the hot gas piston (11) to move leftward again, and the cycle repeats.
