[0006] In one or more embodiments, the burner head is further provided with a central air cavity and a central fire cover matched therewith, a nozzle is provided at the middle position of the central fire cover, and a second ejector tube connected to the central air cavity is provided on the burner head.

[0007] In one or more embodiments, the central air cavity is an annular air cavity, and a relief opening is provided in the middle of the central air cavity for setting the nozzle, and the bottom end interface of the nozzle extends downward through the relief opening to be exposed at the bottom of the furnace head.

[0008] In one or more embodiments, the first ejector tube and the second ejector tube are arranged side by side on the same side of the furnace head.

[0009] In one or more embodiments, an inner fire outlet hole is provided on the inner inclined surface of the outer ring fire cover, and an outer fire outlet hole is provided on the outer surface of the outer ring fire cover.

[0010] In one or more embodiments, the burner head is provided with an ignition needle installation port and a thermocouple installation port on the periphery of the central air cavity.

[0011] Beneficial effects of the utility model: the burner head and the outer ring fire cover of the burner adopt a die-casting integrated structure, which can avoid deformation of the fire cover due to different thermal coefficients of the two materials and deformation caused by improper assembly. In addition, a nozzle is arranged on the central fire cover to realize the direct fire spray function. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] See attached Figure 1-2 The utility model provides a new type of burner, which includes a burner head 1, a first ejector tube 2 and an outer ring fire cover 3. The burner head is formed with an outer ring air cavity 4. The outer ring fire cover is arranged on the outer ring air cavity. The first ejector tube 2 is connected with the outer ring air cavity 4. The outer ring fire cover 3, the burner head 1 and the first ejector tube are a die-cast integrated structure. The outer ring fire cover and the burner head are die-casted as a whole, which can eliminate the installation step of the outer ring fire cover and solve the problem of deformation of the fire cover due to uneven heating.

[0016] The outer edge of the burner head 1 has an outer ring wall 5 extending upward, and the outer ring air cavity 4 is formed inside the outer ring wall. The outer ring wall has a plurality of upper air inlet holes 6 evenly distributed axially, through which fresh air from the outside can enter the inner side of the outer ring air cavity, so that the gas combustion provides oxygen and improves the combustion thermal efficiency of the burner.

[0017] The burner head 1 is also provided with a central air cavity 7 and a central fire cover 8 matched therewith. The central fire cover can be used for convenience when the user switches to low fire cooking. A nozzle 9 is provided in the middle of the central fire cover. The burner head 1 is provided with a second ejector tube 10 connected to the central air cavity. The nozzle can be provided with gas through an independent through-connection, so that the burner has the function of direct fire injection.

[0018] The central air cavity is an annular air cavity, and a relief opening 11 is provided in the middle of the central air cavity for setting the nozzle. The bottom end interface of the nozzle extends downward through the relief opening and is exposed at the bottom of the furnace head. This structure is adopted to facilitate the connection of the nozzle to the gas source.

[0019] The first ejector tube 2 and the second ejector tube 10 are arranged side by side on the same side of the burner head. A cross bar is provided between the first ejector tube and the second ejector tube to strengthen the structure. Adopting this structure can improve the appearance regularity of the burner and facilitate the gas supply of the gas valve to the first ejector tube and the second ejector tube.

[0020] Inner fire outlet holes 12 are provided on the inner inclined surface of the outer ring fire cap 3, and outer fire outlet holes 13 are provided on the outer side surface of the outer ring fire cap. Specifically, the fire outlet holes can be processed and formed according to actual needs, and there is no limitation here.

[0021] Ignition needle installation openings 14 and thermocouple installation openings 15 are provided on the periphery of the burner head around the central gas cavity 7. By providing the ignition needle installation openings 14 and the thermocouple installation openings 15, it is convenient to install the ignition needle and the thermocouple.

[0022] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment.
