For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to 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. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0040] In one embodiment of this utility model, such as Figures 1-6As shown, a burner flame stabilization structure that can be quickly disassembled and assembled is provided, including a base 1, a housing 2, an air regulating mechanism 3, an air intake mechanism 4, an air duct mechanism 5, an ignition mechanism 9, a combustion mechanism 6, a flame stabilization mechanism 7, a quick-release mechanism 8, and an electrical control box 11. The housing 2 is connected to the base 1, the air regulating mechanism 3 is connected to the base 1, the air intake mechanism 4 is connected to the housing 2 and is connected to the ignition mechanism 9 and the combustion mechanism 6 respectively, the air duct mechanism 5 is connected to the housing 2 and is connected to the outside of the air intake mechanism 4, the combustion mechanism 6 is connected to the flame stabilization mechanism 7, the quick-release mechanism 8 is connected to the flame stabilization mechanism 7 and is detachably mounted on the air intake mechanism 4, and the electrical control box 11 is connected to the side of the housing 2.

[0041] The intake mechanism 4 includes a gas pipe 41 and a gas distribution pipe 42. The gas pipe 41 is connected to the housing 2, and the gas distribution pipe 42 is connected to the outside of the gas pipe 41. The combustion mechanism 6 includes a combustion pipe 61 and a flame nozzle 62. One end of the combustion pipe 61 is inserted into the gas pipe 41, and the other end is connected to the flame nozzle 62. The flame stabilization mechanism 7 includes a flame stabilization cover 71 and a swirl vane 72. The swirl vane 72 is connected to the outside of the flame nozzle 62 and is disposed inside the flame stabilization cover 71. The quick-release mechanism 8 includes a positioning ring 81 and a limiting bolt 82. The positioning ring 81 is movably sleeved on the gas distribution pipe 42 and is disposed on one side of the limiting bolt 82. The limiting bolt 82 passes through the gas distribution pipe 42.

[0042] The burner flame stabilization structure provided in this application allows for quick disassembly and assembly. When maintaining or replacing the flame stabilization mechanism 7, simply loosen the limiting bolt 82 and slide the positioning ring 81 along the gas distribution pipe 42 to quickly remove the flame stabilization mechanism 7 from the air intake mechanism 4. The installation process is equally convenient, greatly shortening maintenance time, reducing labor costs, and preventing damage to other components during disassembly and assembly.

[0043] The gas pipe 41 of the air intake mechanism 4 connects to the housing 2 to introduce gas. The gas distribution pipes 42 are evenly distributed outside the gas pipe 41, distributing the gas to each combustion branch. The air regulating mechanism 3's air regulating motor 31 is connected to the electrical control box 11. Through the drive shaft 32, it drives the first air regulating plate 33 to rotate, which in turn causes the driven shaft 35 and the second air regulating plate 36 to rotate synchronously via the swing arm 34, achieving precise adjustment of the air intake volume and providing the appropriate amount of air for gas combustion. The outer air duct 51 and inner air duct 52 of the ductwork mechanism 5 construct a stable channel for the delivery of gas and air. The inner air duct 52 accommodates the gas pipe 41 and the gas distribution pipes 42, ensuring that gas delivery does not interfere with each other.

[0044] In the ignition mechanism 9, the ignition fixing ring 91 is fixed on the outside of the gas pipe 41, and the first ignition needle 92 and the second ignition needle 93 are arranged parallel to each other on it. They generate an electric spark to ignite the gas-air mixture transported by the combustion pipe 61 in the combustion mechanism 6 and sprayed from the flame nozzle 62 nozzle 63, thus starting the combustion process.

[0045] The flame generated by combustion is stabilized by the flame stabilizing mechanism 7. The swirl vane 72 is fixed to the outside of the flame nozzle 62 and located inside the flame stabilizing cover 71, which allows the gas and air to mix fully to form a stable swirl. The flame stabilizing cover 71 then focuses and protects the flame, reducing flame flickering and extinction, and improving combustion efficiency.

[0046] In another embodiment of this utility model, the air regulating mechanism 3 includes an air regulating motor 31, a drive shaft 32, a first air regulating plate 33, a swing arm 34, a driven shaft 35, and a second air regulating plate 36. The air regulating motor 31 is fixedly connected to the base 1 and electrically connected to the electrical control box 11. The drive shaft 32 is fixedly connected to the air regulating motor 31 and rotatably connected to the base 1. The first air regulating plate 33 is fixedly connected to the drive shaft 32. The swing arm 34 is fixedly connected to both the drive shaft 32 and the driven shaft 35. The driven shaft 35 is rotatably connected to the base 1. The second air regulating plate 36 is fixedly connected to the outside of the driven shaft 35. The electrical control box 11 sends a control signal, and the air regulating motor 31 starts operating after receiving the signal. The rotation of the motor drives the fixedly connected drive shaft 32 to rotate. Since the first air regulating plate 33 is fixed on the drive shaft 32, the rotation of the drive shaft 32 will drive the first air regulating plate 33 to rotate synchronously. Simultaneously, the swing arm 34, fixedly connected to the drive shaft 32, also rotates. The rotation of the swing arm 34, in turn, drives the driven shaft 35 to rotate. Since the second air regulating plate 36 is fixed to the outside of the driven shaft 35, the rotation of the driven shaft 35 causes the second air regulating plate 36 to rotate as well. Through the transmission of the drive shaft 32, the swing arm 34, and the driven shaft 35, the rotation of the first air regulating plate 33 and the second air regulating plate 36 is realized, thereby changing the cross-sectional area of ​​the airflow channel and thus adjusting the air intake volume.

[0047] In another embodiment of this invention, multiple gas distribution pipes 42 are provided and are uniformly and annularly fixedly connected to the outside of the gas pipe 41. The multiple gas distribution pipes 42 uniformly connected to the outside of the gas pipe 41 in a ring shape can evenly distribute the gas input from the gas pipe 41 to each branch. Compared to a single pipeline gas supply, this design avoids uneven local gas volume caused by factors such as pipeline resistance during gas transportation, providing a stable and balanced gas supply foundation for subsequent combustion.

[0048] In another embodiment of this utility model, the duct mechanism 5 includes an outer duct 51 and an inner duct 52. The outer duct 51 is fixedly connected to the housing 2, and the inner duct 52 is fixedly connected inside the outer duct 51. The gas pipe 41 and the gas distribution pipe 42 are both disposed inside the inner duct 52. The outer duct 51 and the inner duct 52 provide stable channels for the delivery of air and gas, reducing resistance and fluctuations during gas flow. The outer duct 51 ensures a stable inflow of external air, while the inner duct 52 ensures that the gas is evenly delivered to the combustion mechanism 6, helping to maintain the stability and continuity of combustion.

[0049] In another embodiment of this utility model, the ignition mechanism 9 includes an ignition retaining ring 91, a first ignition needle 92, and a second ignition needle 93. The ignition retaining ring 91 is fixedly connected to the outside of the gas pipe 41, and both the first ignition needle 92 and the second ignition needle 93 are fixedly connected to the ignition retaining ring 91. The first ignition needle 92 and the second ignition needle 93 are arranged parallel to each other and spaced apart. The dual ignition needle design provides double insurance; when one ignition needle fails, the other can still work normally, significantly improving the ignition success rate and reducing the risk of start-up failure. The electric spark generated simultaneously by the dual ignition needles can ignite the gas-air mixture over a larger area, making the flame form more rapidly and distribute more evenly, reducing local unburned phenomena, and improving flame stability.

[0050] In another embodiment of this invention, the flame nozzle 62 has multiple flame holes 63 arranged in a ring-like pattern on its side. These multiple ring-like flame holes 63 allow the gas to be evenly ejected from the side of the flame nozzle 62. Compared to a single flame hole 63, this design avoids localized over-rich or over-lean conditions caused by concentrated gas injection, resulting in a more uniform distribution of the gas before mixing with air, thus laying the foundation for complete combustion.

[0051] In another embodiment of this invention, multiple swirl vanes 72 are provided and uniformly and annularly fixed to the side of the flame nozzle 62. The arrangement of the swirl vanes 72 can change the flow direction of the gas and air, causing them to rotate as they pass through the swirl vanes 72. The multiple swirl vanes 72 are evenly distributed in an annular shape, which can form multiple rotating airflows on the side of the flame nozzle 62, greatly increasing the contact area and mixing degree of the gas and air, allowing them to mix more fully and uniformly, forming a more ideal combustible mixture, and providing good conditions for combustion.

[0052] In another embodiment of the present invention, the positioning ring 81 includes a positioning ring body 811 and a positioning ring 812. The number of positioning rings 812 is the same as that of the air distribution pipe 42, and they are movably sleeved on the air distribution pipe 42. The number of limiting bolts 82 is the same as that of the positioning rings 812.

[0053] The number of positioning rings 812 is the same as that of the gas distribution pipe 42, and they are movably fitted together. This allows the flame stabilizing mechanism 7 to be installed quickly by simply aligning the positioning rings 812 with the gas distribution pipe 42 and fitting them in, and then using the limiting bolts 82 to pass through the gas distribution pipe 42 and fix them to the positioning rings 812. When disassembling, the limiting bolts 82 are loosened, and the positioning rings 812 can slide off along the gas distribution pipe 42. No complicated tools or cumbersome operations are required, which greatly shortens the disassembly and assembly time of the flame stabilizing mechanism 7 and improves maintenance efficiency.

[0054] The burner flame stabilization structure provided in this application allows for quick disassembly and assembly. When maintaining or replacing the flame stabilization mechanism 7, simply loosen the limiting bolt 82 and slide the positioning ring 81 along the gas distribution pipe 42 to quickly remove the flame stabilization mechanism 7 from the air intake mechanism 4. The installation process is equally convenient, greatly shortening maintenance time, reducing labor costs, and preventing damage to other components during disassembly and assembly.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
