[0020] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Referring to Figure 1 , a premix energy-saving and environmental protection automatic flameout protection cooker includes a cooking range 1, a premix burner 2, and an adjusting knob 3. The premix burner 2 can pre-mix fuel gas and air evenly and then burn, and its combustion flame is very stable and compact. At the same time, an automatic flameout protector is provided on the premix burner 2, and the automatic flameout protector includes components such as a flame sensor and a controller.

[0022] When the gas switch of the cooker is turned on and the flame is ignited, the flame sensor will monitor the state of the flame. If the flame is burning normally, it will transmit the detection signal to the controller and inform the controller that the flame exists. If the flame sensor detects that the flame has gone out, which means the flame does not exist, the flame sensor will transmit the detection signal to the controller. At this time, the controller controls the cooker to cut off the gas supply to avoid the problem of gas leakage. The automatic flameout protection of the cooker belongs to the prior art and will not be elaborated here.

[0023] Referring to Figure 2 、 Figure 3 , a damping block 4 is fixedly connected to the outer wall of the adjusting knob 3, and the damping block 4 is made of acrylic or hard plastic.
