When the fireplace door 7 is closed, the fireplace door 7 pushes the pressing rod 34 and the rotating rod 33 to move away from the wall furnace door 7, and then the fixing seat 31 rotates towards the direction approaching to the wall furnace door 7 to abut against the stop block 311 until the air door 2 is closed, and the pressing rod 34 stops moving. When the wall furnace door 7 is opened, the weight 4 of the lower air door 22 drives the upper air door 21 to rotate towards the direction away from the wall furnace door 7 by gravity, the stop block 311 pushes the fixed seat 31 to rotate towards the direction away from the wall furnace door 7, the rotating rod 33 and the pressing rod 34 move towards the direction close to the wall furnace door 7, and the pressing rod 34 extends forwards due to no acting force of the fireplace door 7 on the pressing rod 34, so that the air door 2 is opened. By adopting the automatic baffle slot for control, the fireplace can directly adjust the smoke discharging mode by opening the wall furnace door 7 without using other tools, thereby being convenient and sanitary.
