[0002] The pizza stone is one of the core components of the pizza oven. When grilling pizza, you need to preheat the pizza stone to a certain temperature before putting the pizza on the pizza stone for grilling. There are currently two ways to place pizza stones on the market. One is a fixed pizza stone, which cannot be rotated after being placed, and different parts of the pizza are heated unevenly; the other is a rotatable electric pizza stone, which is driven by a motor to rotate the pizza stone to achieve automatic baking of the pizza, which better solves the problem of uneven heating of different parts of the fixed pizza oven and the inconvenience of rotating the pizza during baking.

[0003] Some existing gas-powered electric rotary pizza ovens include a furnace tube and an ignition pin. During ignition, a certain amount of gas needs to be introduced into the furnace tube first, and then the gas in the furnace tube is ignited by the electric spark emitted by the ignition pin. Since the amount of gas introduced during ignition is difficult to control, the amount of gas introduced into the furnace tube may not be sufficient when the ignition pin is ignited, resulting in the first ignition not being able to ignite smoothly (a secondary ignition is required, which is inconvenient to use, and the secondary ignition is prone to introducing excessive gas). It may also cause excessive gas introduced into the furnace tube to accumulate at the furnace tube or enter the furnace body of the pizza oven, resulting in sudden explosion, fire and other dangerous phenomena when the ignition pin is ignited, thereby causing personal injury and damage to the pizza oven, and the safety of use is low.
