Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner damper adjustment mechanism. Background Technology

[0002] In existing technologies, there are generally two methods for adjusting the burner damper: adjusting the distance and adjusting the area. The method of adjusting the area generally involves setting a fan-shaped notch at the inlet of the stove's injector tube, and then using a fan-shaped notch plate that rotates in conjunction with the fan-shaped notch to change the area of ​​the inlet.

[0003] However, due to structural design flaws, dampers in existing technologies are prone to clogging, affecting oxygen supply and reducing combustion efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a technical solution for a burner damper adjustment mechanism that addresses the shortcomings of existing technologies. This solution not only facilitates the adjustment of the air intake at the burner damper but also ensures stable and reliable air intake, thereby improving the efficiency of air and gas mixing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A damper regulating mechanism for a burner, comprising: Damper plate, the damper plate is connected to the end of the burner's injector tube; Its features are: The damper plate is provided with an air inlet and a positioning hole, with the air inlet evenly distributed along the outer circumference of the positioning hole. Through the design of the above structure, it is not only convenient to adjust the air intake at the burner damper, but also to make the air intake stable and reliable, and improve the efficiency of air and gas mixing.

[0006] Furthermore, it also includes a damper gear and a drive gear. The damper gear is connected to the damper plate through a gas nozzle pipe, and the drive gear is rotatably connected to the damper plate and meshes with the damper gear. The gas nozzle pipe is fixedly connected to the damper plate. The drive gear drives the damper gear to rotate, thereby allowing the damper gear to move along the gas nozzle pipe and adjust the distance between the damper gear and the air inlet to meet the requirements for adjusting the air intake volume.

[0007] Furthermore, a cleaning brush is provided on the side of the damper gear near the damper plate. With the design of the cleaning brush, the damper gear can be rotated to move closer to or away from the air inlet when the burner is not in use, so that the cleaning brush can clean the air inlet, prevent the air inlet from being blocked, improve the oxygen supply efficiency, and further improve the combustion efficiency of the burner.

[0008] Furthermore, the gas nozzle pipe is fixed to the positioning hole, and the gas nozzle pipe is provided with external threads. The center of the damper gear is provided with a through hole, and the through hole is provided with internal threads. The internal threads match the external threads. When the drive gear drives the damper gear to rotate, the damper gear can move horizontally under the action of the internal and external threads, thereby improving the accuracy of oxygen supply.

[0009] Furthermore, the drive gear is fixedly connected to the rotating rod, one end of the rotating rod passes through the damper plate and is connected to the positioning plate, the positioning plate is fixed to the damper plate, and the other end of the rotating rod is connected to a swing plate. By rotating the swing plate, the rotating rod can be driven to rotate, which in turn can drive the damper gear to rotate and move through the drive gear. The positioning plate improves the stability and reliability of the rotating rod installation.

[0010] Furthermore, the thickness of the drive gear is greater than that of the damper gear to meet the requirements for the rotation and movement of the damper gear.

[0011] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: 1. This utility model not only facilitates the adjustment of the air intake at the burner damper, but also ensures stable and reliable air intake, thereby improving the efficiency of air and gas mixing.

[0012] 2. The cleaning brush design allows the damper gear to be rotated near or away from the air inlet when the burner is not in use, enabling the cleaning brush to clean the air inlet, preventing blockage, improving oxygen supply efficiency, and further enhancing the burner's combustion efficiency.

[0018] like Figures 1 to 4 As shown, this utility model discloses a damper adjustment mechanism for a burner, comprising: a damper plate 1, a damper gear 4, and a drive gear 8. The damper plate 1 is connected to the end of the injector tube of the burner.

[0019] The damper plate 1 is provided with an air inlet 2 and a positioning hole 3, and the air inlet 2 is evenly distributed along the outer circumference of the positioning hole 3.

[0020] The damper gear 4 is connected to the damper plate 1 through the gas nozzle pipe 5. The drive gear 8 is rotatably connected to the damper plate 1 and meshes with the damper gear 4. The gas nozzle pipe 5 is fixedly connected to the damper plate 1. The drive gear 8 drives the damper gear 4 to rotate, thereby allowing the damper gear 4 to move along the gas nozzle pipe 5, adjusting the distance between the damper gear 4 and the air inlet 2 to meet the requirements for adjusting the air intake volume.

[0021] A cleaning brush 10 is provided on the side of the damper gear 4 near the damper plate 1. With the design of the cleaning brush 10, the damper gear 4 can be rotated to move closer to or away from the air inlet 2 when the burner is not in use, so that the cleaning brush 10 can clean the air inlet 2, prevent the air inlet 2 from being blocked, improve the oxygen supply efficiency, and further improve the combustion efficiency of the burner.

[0022] The gas nozzle pipe 5 is fixed to the positioning hole 3. The gas nozzle pipe 5 is provided with an external thread 6. The center of the damper gear 4 is provided with a through hole 11. The through hole 11 is provided with an internal thread. The internal thread matches the external thread 6. When the drive gear 8 drives the damper gear 4 to rotate, the damper gear 4 can move horizontally under the action of the internal thread and the external thread 6, thereby improving the accuracy of oxygen supply.

[0023] The drive gear 8 is fixedly connected to the rotating rod 7. One end of the rotating rod 7 passes through the damper plate 1 and is connected to the positioning plate 9. The positioning plate 9 is fixed on the damper plate 1. The other end of the rotating rod 7 is connected to a swing plate. By rotating the swing plate, the rotating rod 7 can be driven to rotate, which in turn can drive the damper gear 4 to rotate and move through the drive gear 8. The positioning plate 9 improves the stability and reliability of the installation of the rotating rod 7.

[0024] The thickness of the drive gear 8 is greater than the thickness of the damper gear 4, which satisfies the rotation and movement requirements of the damper gear 4.

[0025] The above-mentioned structural design not only facilitates the adjustment of the air intake at the burner damper, but also ensures stable and reliable air intake, thereby improving the efficiency of air and gas mixing.

[0026] In practical use, this invention first rotates the rotating rod, which drives the damper gear to rotate via the drive gear and move horizontally, adjusting the distance between the damper gear and the air inlet on the damper plate to meet the requirements for adjusting the air intake volume. After use, rotating the rotating rod brings the damper gear closer to and against the damper plate. Repeatedly rotating the rotating rod allows the cleaning brush on the damper gear to continuously clean the air inlet. After cleaning, rotating the rod returns the damper gear to its original position.

[0027] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to achieve essentially the same technical effect are all covered within the protection scope of this utility model.
