Description

Technical Field

[0002] The main function of the damper adjusting device is to control the amount of air entering the combustion chamber to ensure combustion efficiency and safety. The existing damper adjusting devices on the market include components such as a nozzle seat, a damper baffle, a damper plate, and a nozzle. However, the matching position between the nozzle and the damper baffle is small and not completely centered. When the nozzle is installed, one side of the nozzle will be suspended. If the force applied to tighten the nozzle is large, the damper baffle will deform, and the nozzle will also be misaligned with the ejector pipe due to unilateral force, affecting the ejecting effect. Theoretically, if the nozzle is not matched with the damper baffle but directly with the nozzle seat, this problem can be solved. However, when the damper plate is not positioned with the damper baffle, it is easy to contact the damper / damper baffle first when installing the nozzle.

[0048] An embodiment of the present utility model provides an air damper adjusting device, as Figures 1 - 3As shown, the air mounting base 1 is provided with a mounting hole 11 and an air inlet hole 12 provided on the outer periphery of the mounting hole 11; the door adjusting device includes a mounting base 1, a nozzle 2, a positioning assembly 3 and an air door panel 4. The nozzle 2 is connected to the mounting hole 11. The positioning assembly 3 is located outside the mounting base 1 and connected to the mounting hole 11 for limiting the nozzle 2. The air door panel 4 is connected to the outer periphery of the positioning assembly 3 for adjusting the air inlet area of the air inlet hole 12. In this application, the mounting base 1 is fixedly connected to the ejector tube assembly 7, and the nozzle 2 is in threaded fit with the mounting hole 11 to realize the fixed installation of the nozzle 2. The mounting base 1 of this application integrates the nozzle seat and the air door baffle in the prior art, which not only reduces the number of parts, but also avoids the interference between the air door baffle and the nozzle 2 during installation in the prior art. In addition, through the positioning assembly 3 between the air door panel 4 and the mounting base 1, when the nozzle 2 is installed, it is not easy to interfere with the air door panel 4, ensuring the centering and ejecting performance of the nozzle 2 and improving the installation efficiency of the nozzle 2.

[0049] In a preferred embodiment of the present utility model, as Figures 1 - 3 shown, the positioning assembly 3 includes a positioning ring 31. The nozzle 2 passes through the positioning ring 31 and is inserted into the mounting hole 11. The air door panel 4 is sleeved on the outer periphery of the positioning ring 31 and the nozzle 2 and can rotate along its axis. Among them, one end of the positioning ring 31 is fixedly connected to the mounting hole 11, the other end of the positioning ring 31 abuts against the outer periphery of the nozzle 2, and a limiting surface 20 is provided on the outer periphery of the nozzle 2 for cooperating with the positioning ring 31. In this application, the inner ring surface of the positioning ring 31 is fixedly connected to the mounting hole 11, and its outer ring surface abuts against the limiting surface 20 on the outer periphery of the nozzle 2. Through the surface-to-surface cooperation between the outer ring surface and the limiting surface 20, the centering of the nozzle 2 is good. In addition, the inner diameters of the positioning ring 31 and the mounting hole 11 are the same and their central axes are collinear, and the positioning ring 31 and the mounting base 1 are integrally formed. It can also be understood that the positioning ring 31 is an annular body formed by the mounting hole 11 protruding towards the air inlet direction.
