This invention discloses an ignition structure, a gas stove, and an integrated kitchen system. The ignition structure includes a first gas injector and a valve stem, the valve stem being rotatable between an initial position and a working zone position. The first gas injector has an air inlet on its side. The ignition structure also includes a baffle that moves with the valve stem.

When the baffle moves with the valve stem between the initial position and the ignition position, it can at least partially block the air inlet; when it rotates with the valve stem from the initial position towards the working zone position, it can move away from the air inlet. Therefore, when the valve stem performs the ignition operation, the baffle can block the air inlet, reducing the airflow and preventing flame lift-off due to excessive airflow, thus reducing the probability of flame extinguishing and improving the ignition success rate. When the valve stem rotates to the working zone position, the baffle can rotate to a position away from the air inlet, thereby preventing the baffle from blocking the air inlet and affecting combustion efficiency.
