Description

Technical Field

[0001] This utility model particularly relates to a high-efficiency burner combustion system. Background Technology

[0002] Existing burner combustion systems include a support frame, a burner base mounted on the support frame, and isolated central and external gas supply chambers on the burner base. An external burner cap is mounted on the external gas supply chamber, and a central burner cap is mounted on the central gas supply chamber. Both the external and central burner caps have combustion holes. An injector tube, connected separately to the central and external gas supply chambers, is mounted on the burner base. However, the external gas supply chamber is typically positioned around the central gas supply chamber, and relying solely on a single injector tube to fill the external gas supply chamber with air and gas directly impacts combustion efficiency. Furthermore, relying on a single injector tube may result in uneven mixing of air and gas, often leading to incomplete combustion in larger external gas supply chambers. In addition, the support frame height is fixed, and may not be compatible with different gas stove sizes. Utility Model Content

[0033] The working principle of this utility model is as follows:

[0034] Since the ejector tube is a mature component in this technical field, it is not shown in the accompanying drawings; Figure 1 As shown, taking the annular furnace base 1 as an example, the design concept of this application is illustrated. A central air supply chamber 2 and an external air supply chamber 3, isolated from each other, are spaced apart on the furnace base 1. The external air supply chamber 3 is arranged around the periphery of the central air supply chamber 2. An inner ejector tube is connected to the central air supply chamber 2, and two external ejector tubes are connected to the external air supply chamber 3. The two external ejector tubes are symmetrically arranged around the periphery of the external air supply chamber 3, and each external ejector tube is tangent to the external air supply chamber 3. That is, air and fuel gas are introduced into the external air supply chamber 3 through the two external ejector tubes, respectively, from both sides of the external air supply chamber 3. Compared to the injection method of a single ejector tube, the two external ejector tubes can introduce air more evenly, promoting thorough mixing of air and fuel gas, thereby improving combustion efficiency and enhancing flame stability.

[0035] Based on the above technical solution, this application also installs an installation bracket at the bottom of the stove base 1. As an embodiment 1, the installation bracket can be implemented by a combination of a support plate 71, an adjustment component, and a positioning foot 72. One end of the adjustment component is connected to the stove base 1, and the other end is connected to the support plate 71. Multiple positioning feet 72 are provided at the bottom of the support plate 71. A screw hole 6 is provided at the bottom of each positioning foot 72. During installation, the installation bracket can be fixed by simply passing a screw through the screw hole 6 and connecting it to the gas stove.

[0036] Based on the above technical solution, regarding the adjustment method of the mounting bracket, this application designs the adjustment component to have multiple fixing sleeves 81 on the bottom of the furnace base 1, and positioning posts 82 on the support plate 71. Multiple mounting positions 811 are opened on the fixing sleeves 81 in the vertical direction. That is to say, when the fixing sleeves 81 move up and down relative to the positioning posts 82, the distance between the furnace base 1 and the support plate 71 can be adjusted, thereby adjusting the height of the mounting bracket. When the position between the fixing sleeves 81 and the positioning posts 82 is determined, one end of the locking member is passed through the corresponding mounting position 811 on the fixing sleeves 81 and connected to the positioning posts 82, thereby realizing the connection and fixation between the fixing sleeves 81 and the positioning posts 82. This design can adapt to more installation environments, and the locking member can be implemented with screws.

[0037] Based on the above technical solution, in order to enhance the strength of the positioning leg 72, this application provides a reinforcing rib 721 on the positioning leg 72.

[0038] Based on the above technical solution, the inner side of the outer flame cap 4 of this application is provided with a first mounting surface 41 that is inclined downward, and the combustion holes 50 are distributed at intervals on the first mounting surface 41; similarly, the inner side of the central flame cap 5 is also provided with a second mounting surface 51 that is inclined downward, and the combustion holes 50 are distributed at intervals on the second mounting surface 51; thus, the heat of the flame is more concentrated.
