The inlet of the air inlet is connected to the external gas, and the outlet of the air inlet is connected to the outer ring outlet chamber. During combustion, the gas supply in the outer ring outlet chamber is balanced with the oxygen supply in the air outside the burner cap. When the burner is turned off, the gas supply in the outer ring outlet chamber suddenly decreases, and a large amount of air outside the burner cap rushes into the outer ring outlet chamber. The imbalance between the gas and oxygen supply causes the burner to backfire. Summary of the Invention

[0024] It should be noted that the descriptions of these embodiments are for the purpose of aiding understanding of the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] In the description of this utility model, the terms "upper", "lower", "top" and "bottom" indicate the orientation or positional relationship only for the convenience of describing the invention and not as requiring the utility model to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "set up," "connected," "located in," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a detachable arrangement, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] like Figures 1 to 10 As shown, it is a burner, including a base 1, on which an air inlet 7 and an outer ring fire outlet chamber 3 are respectively provided. The air inlet 7 is located at the bottom of the base 1 and is connected to the outer ring fire outlet chamber 3. The characteristic feature is that an inwardly and upwardly inclined annular air guide plate 4 is provided on the upper part of the outer ring fire outer wall 31 of the outer ring fire outlet chamber 3.

[0028] After the burner is turned off, the gas supply in the outer ring gas outlet chamber 3 suddenly decreases. Under the action of the annular air guide plate 4, the air outside the burner cap will not rush into the outer ring gas outlet chamber in a large amount quickly. The supply of gas and oxygen is not unbalanced, and the burner will not produce backfire.

[0029] In this embodiment, an outer ring step 32 is provided on the outer ring fire outer wall 31, and the annular gas guide plate 4 is provided on the inner side of the outer ring step 32.

[0030] The outer ring step 32 can create a certain distance between the annular gas guide plate 4 and the burner cap, further enabling more complete combustion in the outer ring burner outlet chamber 3.

[0031] In this embodiment, the angle at which the annular air guide plate 4 tilts inward and upward is 'a', and the range of 'a' is 30°-89°. The angle of 'a' can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, and 89°, etc.

[0032] In this embodiment, an air inlet mounting base 10 is also included, the upper end of which is engaged with the outer wall 71 of the air inlet 7.

[0033] Currently, most burners are made of iron or aluminum. After prolonged use and under high-temperature conditions, the burner and the burner head will corrode and stick together, making disassembly and maintenance inconvenient. This air inlet mounting bracket 10 is made of a non-corrosion-resistant material (such as stainless steel), so the burner and burner head will not stick together, making maintenance and disassembly convenient.

[0034] In this embodiment, a central flame outlet mounting base 9 is also included. A central flame outlet 6 is provided on the base 1. The inlet of the central flame outlet 6 is connected to the air inlet 7, and the outlet of the central flame outlet 6 is located in the middle of the outer ring flame outlet chamber 3. The central flame outlet mounting base 9 is engaged with the outer wall of the inlet of the central flame outlet 6.

[0035] Currently, most burners are made of iron or aluminum. After prolonged use and under high-temperature conditions, the burner and the burner head will corrode and stick together, making disassembly and maintenance inconvenient. This air inlet mounting bracket 10 is made of a non-corrosion-resistant material (such as stainless steel), so the burner and burner head will not stick together, making maintenance and disassembly convenient.

[0036] In this embodiment, a gas equalization plate 5 is also included. The gas equalization plate 5 is inclined downward, with one end of the gas equalization plate 5 disposed on the annular gas guide plate 4 and the other end of the gas equalization plate 5 disposed on the inner wall of the outer annular fire.

[0037] In this embodiment, an air guide channel 2 is provided on the base 1, and the air inlet 7 is connected to the outer ring fire outlet chamber 3 through the air guide channel 2.

[0038] In this embodiment, an inwardly and upwardly inclined central flame guide plate 62 is provided on the upper part of the central flame outer wall 61 of the central flame outlet 6.

[0039] In this embodiment, an inner ring step 63 is provided on the outer wall 61 of the central flame outlet 6, and the central flame guide plate 62 is located on the inner side of the inner ring step 63.

[0040] The inner ring step 63 can create a certain distance between the central fire guide plate 62 and the flame cap, further enabling more complete combustion in the outer ring fire outlet chamber 3.

[0041] The embodiments of this utility model have been described in detail above, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations of these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
