[0002] With the development of gas stoves, most of the burners of gas stoves sold on the market are down-air burners, which are used for embedded gas stoves. When the gas stove is embedded in the cabinet, the primary air required for combustion needs to pass through the cabinet and then to the bottom shell of the gas stove, and then to the burner. This has many shortcomings: 1. Air inlets need to be opened in the cabinet to ensure sufficient air, but after the air inlets are opened, pests such as cockroaches and mice can easily enter and damage the structure of the gas stove; 2. When opening and closing the cabinet door, the flame will flutter or even go out, posing a safety hazard; 3. During use, there is a lack of primary air, resulting in incomplete combustion and low thermal efficiency; 4. When the down-air burner backfires, it is easy to cause cabinet combustion, panel explosion and other dangerous events.

[0003] Moreover, most of the downward air-inlet burners are used in integrated stoves, which have the defects of occupying a large space, inconvenient damper adjustment, and high product temperature. Summary of the invention
