When the cooker leaves, the telescopic contact 41 is lifted and reset to a pot state, the fire blocking piece 5 moves upwards along with the pot state and blocks the fire outlet 12, the flame detection mechanism 2 cannot detect flame, no signal is sent out, the controller 3 cannot control the gas control valve of the big fire cover to be closed after receiving the signal, and therefore the outer ring flame is extinguished, and only the inner ring small fire is reserved. In this scheme, when cooking utensils use during the pan did not put or remove, can detect the pan, through flame detection to pan physical displacement structurally, turned into the signal of telecommunication, the gas passageway of big fire lid is closed to the mode of utilizing controller 3 control big fire lid gas control valve again, reaches the purpose that only keeps little fire, and flame detection mechanism 2 is owing to its self functional feature, therefore its adaptable high temperature environment, long service life is difficult to produce misjudgement.
Further, the large fire cover gas control valve is in a normally open state between the ignition of the burner and the detection of the flame detection mechanism by the controller 3; and after a preset time after ignition, the controller 3 detects whether the flame detection mechanism emits a signal. That is, when the burner is used, the cooker is normally ignited and used, and the big fire cover gas control valve is in a normally open state no matter the cooker is provided or not, and flames are generated on the big fire cover and the small fire cover 1. After a period of time, approximately 5-10 min, the controller 3 judges the signal of the flame detection mechanism; if the signal exists, the gas control valve of the big fire cover is unchanged; and closing the gas control valve of the big fire cover if no signal exists. Therefore, the normal use of the burner can be ensured, and the problem that the big fire cannot be used due to the problem of the related parts for realizing the effect of the small fire from the pot is avoided.
