The outer gas ring groove is covered with a cantilevered gas cover, and the cantilevered gas cover is not in contact with the side of the flame stabilizing groove.

[0005] In the above-mentioned flameout prevention burner, the inner gas ring groove is located at the center of the outer gas ring groove, an outer ring wall is provided on the side of the outer gas ring groove away from the inner gas ring groove, and an inner ring wall is provided on the other side of the outer gas ring groove. The gas groove and the flame stabilizing groove are respectively provided on the upper end face of the outer ring wall and the inner ring wall.

[0006] In the aforementioned flameout-proof burner, the gas groove section includes a first gas groove and a second gas groove. The first gas groove is formed on the outer ring wall, and the second gas groove is formed on the inner ring wall. The flame stabilizing groove section includes a first flame stabilizing groove and a second flame stabilizing groove. The first flame stabilizing groove is disposed on one side of the first gas groove, and the second flame stabilizing groove is disposed on one side of the second gas groove. The cantilevered gas cover is disposed on the upper end of the first gas groove, the second gas groove, the first flame stabilizing groove, and the second flame stabilizing groove.

[0007] In the aforementioned flameout-proof burner, a central hole is provided in the middle of the cantilevered gas cover, the inner gas ring groove is located in the central hole, an inner convex ring is provided on the edge of the central hole, an outer convex ring is provided on the edge of the cantilevered gas cover away from the central hole, a groove is formed between the outer convex ring and the inner convex ring, the groove is provided on the upper end of the outer gas ring groove, so that a first gap is formed between the inner side of the outer convex ring and the first flame stabilizing groove, and a second gap is formed between the inner side of the inner convex ring and the second flame stabilizing groove.

[0008] In the aforementioned flameout-proof burner, the side of the outer convex ring near the first flame stabilizing groove is an inclined surface.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Combination Figures 1 to 6 The illustrated anti-flameout burner includes a burner body 1. The burner body 1 has a concentric outer gas ring groove 2 and an inner gas ring groove 3. The upper surfaces of both sides of the outer gas ring groove 2 are respectively provided with multiple gas grooves. A flame stabilizing groove is provided between each pair of adjacent gas grooves. A cantilevered gas cover 6 is provided on the outer gas ring groove 2. The cantilevered gas cover 6 does not contact the side of the flame stabilizing groove. In this embodiment, the gas grooves and flame stabilizing grooves are integrally set on the outer gas ring groove 2. The cantilevered gas cover 6 covers the gas grooves and flame stabilizing grooves to prevent the soup from directly covering the gas grooves and flame stabilizing grooves when it falls, thereby preventing the flame from going out. Moreover, the fact that the cantilevered gas cover 6 does not contact the side of the flame stabilizing groove allows the premixed gas to have a delayed residence time after output, so that the premixed gas can have better contact with the air, allowing the flame root to burn quickly and completely, and preventing flame instability.

[0020] In this embodiment, the inner gas ring groove 3 is located at the center of the outer gas ring groove 2. An outer ring wall 4 is provided on the side of the outer gas ring groove 2 away from the inner gas ring groove 3, and an inner ring wall 5 is provided on the other side of the outer gas ring groove 2. The gas groove and the flame stabilizing groove are respectively provided on the upper end face of the outer ring wall 4 and the inner ring wall 5. This makes the gas groove, the flame stabilizing groove and the outer gas ring groove 2 form an integral structure. It can be formed by slotting the upper end face of the outer ring wall 4 and the inner ring wall 5, which simplifies the manufacturing process.

[0021] The gas groove section of this embodiment includes a first gas groove 7 and a second gas groove 10. The first gas groove 7 is formed on the outer ring wall 4, and the second gas groove 10 is formed on the inner ring wall 5. The flame stabilizing groove section includes a first flame stabilizing groove 8 and a second flame stabilizing groove 11. The first flame stabilizing groove 8 is disposed on one side of the first gas groove 7, and the second flame stabilizing groove 11 is disposed on one side of the second gas groove 10. The cantilevered gas cover 6 covers the upper ends of the first gas groove 7, the second gas groove 10, the first flame stabilizing groove 8, and the second flame stabilizing groove 11. Both the flame groove 8 and the second flame stabilizing groove 11 are grooves with open tops. The depth of the first gas groove 7 is greater than that of the first flame stabilizing groove 8, and the depth of the second gas groove 10 is greater than that of the second flame stabilizing groove 11. This allows the cantilevered gas cover 6 to better shield the sides of the first flame stabilizing groove 8 and the second flame stabilizing groove 11, enabling the premixed gas to be better output to the space between the cantilevered gas cover 6 and the side of the flame stabilizing groove. This allows the premixed gas to better provide combustion gas to the flame root, making the flame more stable and preventing accidental flameout.

[0022] In this embodiment, the cantilever gas cover 6 has a central hole 15 in the middle, and the inner gas ring groove 3 is located in the central hole 15. An inner convex ring 17 is provided on the edge of the central hole 15, and an outer convex ring 16 is provided on the edge of the cantilever gas cover 6 away from the central hole 15. A groove 18 is formed between the outer convex ring 16 and the inner convex ring 17. The groove 18 covers the upper end of the outer gas ring groove 2, so that a first gap 19 is formed between the inner side of the outer convex ring 16 and the first flame stabilizing groove 8, and a second gap is formed between the inner side of the inner convex ring 17 and the second flame stabilizing groove 11. Thus, the premixed gas output from the first gas groove 7 and the first flame stabilizing groove 8 can fill the first gap 19, so that the premixed gas can better provide combustion for the flame root. Similarly, the second gap can also be filled with premixed gas through the second gas groove 10 and the second flame stabilizing groove 11 to provide combustion for the flame root, so that both sides of one outer gas ring groove 2 can burn simultaneously.

[0023] It is worth noting that in this embodiment, the side of the outer convex ring 16 near the first flame stabilizing groove 8 is a slope 9; the slope 9 can guide the premixed gas in the first gap 19 downward, allowing the premixed gas to better contact the root of the flame. Similarly, the inner side of the second gap can also adopt a slope structure.

[0024] In this embodiment, a plurality of support blocks 12 are provided on the side of the inner ring wall 5 near the inner gas ring groove 3. The upper surface of the plurality of support blocks 12 is lower than the upper surface of the inner ring wall 5. A limiting protrusion 13 is provided on one side of the upper end of the plurality of support blocks 12, so that the limiting protrusion 13 and the inner ring wall 5 form an inner convex ring groove 14. This ensures that after the cantilever gas cover 6 is installed, it can better ensure that the position is the same each time, and can also ensure that the spatial changes of the first gap 19 and the second gap can remain the same, preventing flame instability.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
