[0004] The utility model is realized as follows: A burner base for a burner head is characterized in that: the burner base for a burner head includes a circular bottom plate, a central burner cap seat and a central air inlet pipe, an outer-ring air inlet interface, a radial gas channel, an axial secondary air channel and an outer-ring gas groove. The radial gas channel is communicated with the outer-ring air inlet interface and the outer-ring gas groove, and the central air inlet pipe extends into the outer-ring air inlet interface.

[0005] A circular flow deflector is provided on the outer-ring wall plate of the outer-ring gas groove, and a radial gas groove communicated with the radial gas channel and an annular diversion groove are provided on the bottom plate.

[0006] The burner base for a burner head is characterized in that: a flow buffering cavity communicated with the central air inlet pipe and a flow guiding plate are provided in the central burner cap seat. The flow buffering cavity includes an axial air outlet hole provided on the top plate and a radial air outlet hole provided on the circumferential wall plate. One end of the flow guiding plate is connected to the circumferential end of the radial air outlet hole.

[0007] The burner base for a burner head is characterized in that: a circular arc-shaped protrusion with a hollow lower opening is provided on the bottom plate of the outer-ring gas groove, the gap between the circular arc-shaped protrusions forms the radial gas groove, and the gap between the circular arc-shaped protrusion and the outer-ring wall plate forms the annular diversion groove.

[0008] The described burner sub - burner base is characterized in that: the radial gas passage has an acute - angle with the horizontal plane on the outer side of the radial direction.

[0009] In the burner sub - burner base of the present utility model, the arrangement of the radial gas groove, the annular diversion groove and the top - circular annular diversion plate in the outer - ring gas groove realizes uniform gas distribution and prevents the generation of flying flames.

[0015] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0016] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0017] As Figure 1 shown, a burner sub - burner base includes a circular bottom plate 1, a central burner cap seat 2, a central air inlet pipe 3, an outer - ring air inlet interface 4, a radial gas passage 5, an axial secondary air passage 6 and an outer - ring gas groove 7. The radial gas passage 5 is communicated with the outer - ring air inlet interface 4 and the outer - ring gas groove 7, and the central air inlet pipe 3 extends into the outer - ring air inlet interface 4;

[0018] On the outer - ring wall plate of the outer - ring gas groove 7, a circular flow - disturbing plate 71 is provided, and on the bottom plate, a radial gas groove 72 communicated with the radial gas passage 5 and an annular diversion groove 73 are provided.
