Why does the gas stove always turn off automatically?

The element that controls the air valve is broken, so it won't catch fire after a while;

If the extinguishing is slow, check whether the connected hose is squeezed or bent, so that the natural gas cannot pass normally.

If the gas stove is advanced, see if the battery is dead;

There is not much gas in the gas stove, so there is no pressure to squeeze it out evenly.
