detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a burner burner for a stove includes a burner body 1, a central air outlet pipe 2, an annular outer ring premixing chamber 3 surrounding the central air outlet pipe, a central The ejector pipe 4 and the outer ring ejector pipe 5 , the central ejector pipe 2 communicates with the central air outlet pipe 4 , and the outer ring ejector pipe 5 communicates with the outer ring premixing chamber 3 .

The front part of the burner body 1 is provided with an air chamber 6 with an upper opening, the rear part is provided with a guide chamber 7, and the two sides are provided with a shunt chamber 8; the shunt chamber 8 is arranged on the left and right; the burner body 1 is also provided with an ignition needle 17 and sensing pin 18.

The central injection tube 4 is located above the outer ring injection tube 5, and the inlet ends of the central injection tube 4 and the outer ring injection tube 5 are connected to the rear wall plate of the air cavity 6 and communicate with the air cavity 6;

The gas outlet end of the outer ring ejector tube 5 communicates with the middle part of the diversion chamber 7, one end of the diversion chamber 8 communicates with the end of the diversion chamber 7, and the other end communicates with the outer ring premixing chamber 3;
