The application relates to a gas stove and a burner thereof. The burner comprises an ejector pipe group and a damper end plate. The ejector pipe group has an air inlet end and an air outlet end, and a booster hole is arranged in the side wall of the ejector pipe group close to the air inlet end; the damper end plate is arranged at the air inlet end of the ejector pipe group, and a primary air inlet hole and a gas hole are arranged in the damper end plate. External air can be sucked into the ejector pipe group through the booster hole and the primary air inlet hole at the same time, the booster hole is used for increasing the air intake amount, facilitating further promotion of combustion, improving the combustion efficiency and reducing the CO emission amount. The booster hole is arranged in the side wall of the ejector pipe group close to the air inlet end, and the primary air inlet hole is arranged on the damper end plate, that is, the air flow direction of the air entering from the booster hole is different from the air flow direction of the air entering from the primary air inlet hole. Therefore, when the two air flows flow into the ejector pipe group at the same time, the two air flows collide and mix, the air and the gas are fully mixed, the combustion efficiency is improved, and the CO emission amount is reduced.
