[0032] Reference Figures 1 to 4 The following are several embodiments of the burner head of this utility model.

[0033] like Figures 1 to 4As shown, the burner head of the first aspect embodiment of this utility model includes a base 100, a flame distributor, and a flame detection needle 300; the base 100 is provided with an air intake channel; the flame distributor includes a flame distributor element 210, which is provided with a mixing chamber that communicates with the air intake channel; the flame distributor element 210 is provided with a first permanent flame hole 211 and a second permanent flame hole 212, the first permanent flame hole 211 being located on the top surface of the flame distributor element 210 and the second permanent flame hole 212 being located on the side surface of the flame distributor element 210; the flame detection needle 300 is disposed on the flame distributor and located on one side of the second permanent flame hole 212; the flame detection needle 300 is used to detect the flame of the second permanent flame hole 212.

[0034] Gas enters the mixing chamber of the burner 210 through the air intake channel of the base 100. After premixing, it is ejected and burned from the first long flame hole 211 on the top surface of the base 100 and the second long flame hole 212 on the side of the base 100. The flame detection needle 300 is located on one side of the second long flame hole 212 and detects the flame status of the second long flame hole 212. The second long flame hole 212 is located on the side of the burner 210. The second long flame hole is less affected by the bottom of the pot and is not disturbed by the airflow at the bottom of the pot. It can maintain a stable combustion height, which makes it easy for the flame detection needle 300 to continuously sense the flame signal. This avoids the flame from rising out of the detection area due to the first long flame hole at the top of the burner head, which could lead to false judgment of flameout and cut off the gas supply.

[0035] The first permanent flame port 211 is located on the top surface of the flame distribution element 210. When the pot is placed on the burner, the flame from the first permanent flame port 211 heats the pot. If a flame detection needle 300 is used to detect the flame from the first permanent flame port 211, since the first permanent flame port 211 is located on the top surface of the flame distribution element 210, the flame detection needle 300 typically needs to be a bent needle with an angle of 45 to 90 degrees. Bent needles have a higher failure rate and shorter lifespan. In addition, wastewater and food ingredients can accumulate on the flame detection needle 300, easily interfering with its normal operation and causing it to fail to detect the flame. Furthermore, when small pots are placed on the burner, the bottom of the pot can easily touch the flame detection needle 300, causing unnecessary risks. In this embodiment of the invention, the second permanent flame hole 212 is located on the side of the flame distribution member 210. This effectively prevents the bottom of small pots from touching the flame detector needle 300, improving the stability of the flame detector needle 300's operation and extending its lifespan. By placing the flame detector needle 300 at the second permanent flame hole 212 on the side of the flame distribution member 210, and utilizing the characteristics of the second permanent flame hole 212 being less obstructed by the bottom of the pot and having sufficient air supply, the flame height is ensured to be stable and continuously cover the flame detector needle 300. This fundamentally avoids misjudgment of the flame signal caused by the rising flame at the bottom of the first permanent flame hole 211 on the top surface of the furnace body, significantly improving the reliability of the flameout protection, while ensuring uninterrupted gas supply, improving combustion efficiency and operational safety.

[0036] like Figures 1 to 2 As shown, in some embodiments, one end of the flame detection needle 300 is provided with a sensing head 320. The sensing head 320 is bent towards the second propellant hole 212, and the bending angle of the sensing head 320 is less than or equal to 20°, so that the sensing head 320 accurately points to the root of the emitted flame, ensuring the accuracy of the sensing head 320 in detecting the flame combustion. When the furnace head is working, the flame emitted from the second propellant hole 212 burns stably. The sensing head 320 is bent towards the second propellant hole 212, so that the sensing head 320 is closer to the second propellant hole 212, so as to more accurately judge the flame combustion and reduce the risk of misjudgment. In other embodiments, the flame detection needle 300 can be a straight needle, that is, the sensing head 320 extends straight out relative to the needle body of the flame detection needle 300.

[0037] like Figure 1 As shown, in some embodiments, the flame distribution element 210 includes an inner ring 213 and an outer ring 214, with the outer ring 214 fitted over the inner ring 213. Both the outer ring 214 and the inner ring 213 are provided with first permanent flame holes 211, and both the inner ring 213 and the outer ring 214 are provided with mixing chambers to accommodate different usage scenarios. During high-heat cooking, the first permanent flame holes 211 of both the inner ring 213 and the outer ring 214 emit flames to quickly heat the cookware. During low-heat cooking, only the first permanent flame hole 211 of the inner ring 213 emits a flame, allowing for concentrated heating of the center of the cookware. The air intake channel includes a first channel and a second channel. The first channel connects to the mixing chamber of the inner ring 213 to deliver gas to the inner ring 213; the second channel connects to the mixing chamber of the outer ring 214 to deliver gas to the outer ring 214.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the flame distributor also includes a connector 220, which is connected to the inner ring 213 and the outer ring 214. The connector 220 is provided with a mounting groove 221 for the flame detector 300. The flame detector 300 can be stably installed on the flame distributor through the mounting groove 221. The mounting groove 221 is located on the connector 220. When using small-sized cookware, the cookware is placed on the inner ring 213, and it is not easy to press down on the flame detector 300.

[0039] like Figure 1 As shown, in some embodiments, the second permanent flame hole 212 is disposed on the side of the inner ring 213 near the connector 220. The stable flame of the second permanent flame hole 212 improves the reliability of the detection by the flame detector 300. The upper surface of the connector 220 is lower than the upper surface of the inner ring 213, and the flame detector 300 is mounted on the connector 220 to avoid the flame detector 300 protruding from the inner ring 213, thereby avoiding the flame detector 300 from colliding with the bottom of the pot.

[0040] like Figures 1 to 3As shown, in some embodiments, the outer periphery of the flame detection needle 300 is provided with a mating protrusion 310, and the connector 220 is provided with a limiting groove 222 communicating with the mounting groove 221. The mating protrusion 310 is fixed in the limiting groove 222. The displacement of the mating protrusion 310 is restricted by the limiting groove 222 to fix the flame detection needle 300 in the mounting groove 221, thereby enhancing the stability of the installation of the flame detection needle 300 and preventing the sensing head 320 from shaking during operation. This embodiment of the present invention also includes a bolt. A first threaded hole is provided on the mating protrusion 310, and a second threaded hole is provided at the bottom of the limiting groove 222. The bolt passes through the first threaded hole and connects with the second threaded hole to fix the mating protrusion 310 in the limiting groove 222.

[0041] like Figure 3 As shown, in some embodiments, the flame detector 300 has mating protrusions 310 on opposite sides, and correspondingly, there are two limiting grooves 222 to securely mount the flame detector 300 in the mounting groove 221.

[0042] like Figures 3 to 4 As shown, in some embodiments, multiple limiting grooves 222 are provided, and the multiple limiting grooves 222 are evenly distributed on the outer periphery of the mounting groove 221. The rotation angle of the flame detector 300 can be adjusted by setting the mating protrusion 310 in different limiting grooves 222, so that the sensing head 320 can be positioned toward the second permanent flame hole 212.

[0043] like Figure 1 As shown, in some embodiments, a first support frame 230 is provided on the burner, which is used to support the pot. By providing the first support frame 230 on the burner, a reliable support is formed between the bottom of the pot and the burner head, so that there is a sufficiently large gap between the bottom of the pot and the top surface of the burner, ensuring sufficient air supply to the combustion zone and reducing the phenomenon of flame bottom rising.

[0044] like Figure 2 As shown, in some embodiments, a second support frame 240 is provided at the bottom of the base 100. The second support frame 240 is used to support the base 100 and enhance the overall stability of the base 100. The design of the second support frame 240 allows the base 100 to be more firmly fixed in the predetermined position during installation, effectively preventing the base 100 from shaking or shifting during use. At the same time, the second support frame 240 also plays a certain role in heat insulation, reducing heat conduction between the bottom of the burner head and the contact surface, further improving the safety and durability of the burner head.

[0045] like Figures 1 to 4 As shown, a stove provided in the second aspect embodiment of the present invention includes a burner head as described in the first aspect embodiment.

[0046] It is understood that if the burner has the beneficial effects of the above embodiments, then the stove will have the corresponding beneficial effects of the above embodiments. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
