Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a multi-purpose burner component. Background Art

[0002] At present, most of the upper air inlet burners on the market are of the two-ring fire type. This structure easily forms a blank area of ​​the flame at the bottom center of the pot bottom, which has a certain impact on the uniformity of the flame.

[0003] At the same time, since the flame is ejected outward, the flame diameter increases, and the energy efficiency utilization rate will be low for small-diameter cookware. Utility Model Content

[0004] The utility model aims to provide a technical solution of a multi-purpose burner assembly to address the deficiencies in the prior art, which can not only spray flames from the middle to increase the heating area of ​​the pot bottom, prevent the formation of a flame blank area in the center of the pot bottom and improve energy efficiency, but also facilitate the disassembly and assembly of the separation assembly and the inner ring fire cover to meet different usage requirements.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A multi-purpose burner assembly comprising

[0007] One stove;

[0010] Features:

[0011] The base is detachably connected to a partition assembly, and an inner ring fire cover is assembled on the base and the partition assembly. The partition assembly is connected to the central fire outlet hole of the inner ring fire cover, and a central fire air intake assembly is provided on the burner head. The mixed gas is sprayed out of the central fire outlet hole through the partition assembly through the central fire air intake assembly to heat the blank area in the center of the pot bottom. Through the design of the above structure, not only can the flame be sprayed out from the middle to increase the heating area of ​​the pot bottom, prevent the formation of a flame blank area in the center of the pot bottom, and improve energy efficiency, but also the partition assembly and the inner ring fire cover are easy to disassemble and assemble to meet different usage requirements.

[0012] Furthermore, the partition assembly includes an integrally formed partition tube and a conical cover, the top of the partition tube is against the inner ring fire cover, the conical cover is clamped in the inner ring fire cover seat of the base, a vent is provided in the partition tube, a conical cavity is provided in the conical cover, the conical cavity is connected to the vent, and is used to transport air to the central fire outlet together with the gas. When the conical cover is connected to the inner ring fire cover seat, the inner ring fire cover is assembled to form an independent space between the interior of the partition assembly and the inner ring fire cover seat, so that the mixed gas can be transported in different directions. The conical cavity is beneficial for bringing air into the vent during the process of the gas being sprayed into the vent, which is beneficial for mixing air and gas and improving combustion efficiency.

[0013] Furthermore, a first sleeve protruding toward the separation tube is provided at the center of the inner ring fire cover, and the central fire hole vertically penetrates the first sleeve. A limiting hole is provided on the top of the separation tube. When the first sleeve is inserted into the limiting hole for limiting, the air vent and the central fire hole are connected to each other. Through the design of the limiting hole and the first sleeve, not only the assembly stability between the inner ring fire cover and the separation assembly is improved, but also the mixed gas is facilitated to be output from the central fire hole through the air vent, thereby improving the stability of the flame.

[0015] Furthermore, an annular retaining ring is provided on the inner ring fire cover on the opposite side of the first sleeve, and the annular retaining ring protrudes from the top surface of the inner ring fire cover. When water from the bottom of the pot flows out, it is blocked by the annular retaining ring, causing the water to flow to the outside of the inner ring fire cover, thereby reducing the probability of the central nozzle being blocked.

[0016] Furthermore, a second sleeve is provided on the inner ring fire cover on the same side of the first sleeve, and an inner ring fire outlet hole is provided on the outer circumferential side of the second sleeve. The second sleeve is assembled on the inner ring fire cover seat to improve the installation stability and reliability of the inner ring fire cover. The inner ring fire distribution cavity of the inner ring fire cover seat can output the mixed gas through the inner ring fire outlet hole to generate an inner ring flame.

[0017] Furthermore, the length of the second sleeve is greater than that of the first sleeve, which facilitates the assembly of the inner ring fire cover.

[0018] Furthermore, the center fire air intake assembly includes a gas supply pipe, a solenoid valve, a center fire air intake pipe and a center nozzle. The solenoid valve is arranged on the gas supply pipe. The gas supply pipe is connected to the burner head through the center fire air intake pipe.

The solenoid valve can control the amount of gas input into the center fire air intake pipe through the gas supply pipe, and the gas is sprayed into the air hole through the center nozzle.

[0019] Furthermore, the central nozzle, the air vent and the central flame outlet are located on the same straight line, which is not only conducive to the gas carrying air into the air vent, but also allows the gas and air to mix during the transportation process, thereby improving the stability of the middle flame.

[0020] Furthermore, the burner head is provided with an inner ring fire air inlet and an inner ring fire nozzle seat which are interconnected, and at least one outer ring fire air inlet and an outer ring fire nozzle seat which are interconnected. The gas supply pipe is connected to the inner ring fire air inlet or the outer ring fire air inlet, which is conducive to diverting the gas in the inner ring fire air inlet or the outer ring fire air inlet to the center fire air inlet pipe through the gas supply pipe, thereby meeting the requirement of heating the blank area in the center of the pot bottom.

[0021] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0022] 1. The utility model can not only spray flames from the middle to increase the heating area of ​​the pot bottom, prevent the formation of a flame blank area in the center of the pot bottom, and improve energy efficiency, but also facilitate the disassembly and assembly of the separation component and the inner ring fire cover to meet different usage requirements.

[0023] 2. After the conical cover is connected to the inner ring fire cover seat, the inner ring fire cover is assembled to form an independent space between the interior of the partition assembly and the inner ring fire cover seat, so that the mixed gas can be transported in different directions. The conical cavity is conducive to bringing air into the vent hole during the process of gas spraying into the vent hole, which is beneficial to the mixing of air and gas and improves combustion efficiency.

[0024] 3. The annular retaining ring protrudes from the top surface of the inner ring fire cover. When the water from the bottom of the pot flows out, it is blocked by the annular retaining ring, so that the water flows to the outside of the inner ring fire cover, reducing the probability of the central nozzle being blocked.
