Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] Reference Figures 1 to 8 This utility model provides an embodiment of a flame distributor, which includes a base 100 and an injector 400. The upper surface of the base 100 has an inner ring gas passage 200 and an outer ring gas passage 300, with the outer ring gas passage 300 surrounding the outer periphery of the inner ring gas passage 200. The injector 400 is located below the base 100, and its air inlet passage 410 is connected to the outer ring gas passage 300. The base 100 also has a connecting portion 500 located between the inner ring gas passage 200 and the outer ring gas passage 300. The connecting portion 500 has a connecting passage 510. The bottom wall of the inner ring gas passage 200 has a first connecting hole 210 connected to the connecting passage 510, and the bottom wall of the outer ring gas passage 300 has a second connecting hole 310 connected to the connecting passage 510.

[0039] By employing the ignition distributor of this utility model embodiment, the ignition distributor is provided with only one injector tube 400. The intake passage 410 of the injector tube 400 is connected to the outer ring gas passage 300. A connecting part 500 is provided between the inner ring gas passage 200 and the outer ring gas passage 300. A connecting passage 510 is provided on the connecting part 500. The bottom wall of the inner ring gas passage 200 has a first connecting hole 210 that communicates with the connecting passage 510, and the bottom wall of the outer ring gas passage 300 has a second connecting hole 310 that communicates with the connecting passage 510. Thus, the gas can be supplied through the connecting passage 510. The inner ring gas passage 200 and the outer ring gas passage 300 are connected, allowing the gas in the outer ring gas passage 300 to flow into the inner ring gas passage 200 through the connecting passage 510. Thus, gas can be delivered to the inner ring gas passage 200 and the outer ring gas passage 300 through a single injector tube 400. Since the burner in this embodiment of the invention is equipped with only one injector tube 400, the structure of the burner is simpler. During use, only one nozzle needs to be configured for the injector tube 400, making it more convenient to use. It also helps to simplify the overall structure of the burner and reduce costs.

[0040] Understandably, both the ejector tube 400 and the connecting part 500 are located below the base 100, so that the ejector tube 400 and the connecting part 500 can support the base 100, thereby improving the structural strength of the fire distributor.

[0041] Reference Figures 1 to 8 In some embodiments, a first guide surface 211 is provided around the periphery of the first connecting hole 210, and the first guide surface 211 extends from top to bottom toward the connecting channel 510.

[0042] In the above structure, the first guide surface 211 can guide the gas in the connecting channel 510 to flow upward along the first guide surface 211 into the inner ring gas channel 200, avoiding the phenomenon of gas flowing rapidly in the connecting channel 510 and colliding with the end wall of the connecting channel 510, which would cause airflow turbulence, so that the gas can flow more smoothly from the outer ring gas channel 300 into the inner ring gas channel 200.

[0043] It is understood that the first guide surface 211 can be an arc-shaped guide surface or a guide slope, and this utility model does not specifically limit it in this regard.

[0044] Reference Figures 1 to 8 In some embodiments, the bottom wall of the outer ring gas passage 300 is provided with a downwardly recessed groove 320, the ejector tube 400 is located below the inner ring gas passage 200 and extends toward the groove 320, and the inner wall of the groove 320 near the inner ring gas passage 200 is provided with a third connecting hole 321 that communicates with the air intake passage 410.

[0045] In the above structure, by setting a groove 320 on the bottom wall of the outer ring gas passage 300 and opening a third connecting hole 321 on the side wall of the groove 320, the air intake passage 410 of the ejector tube 400 can be directly connected to the groove 320 through the third connecting hole 321. The gas in the air intake passage 410 can first flow along the air intake passage 410 to the groove 320, and then flow upward to the outer ring gas passage 300 and flow along the circumference of the outer ring gas passage 300. When some gas flows along the outer ring gas passage 300 to the second connecting hole 310, it can also flow through the connecting passage 510 to the first connecting hole 210, and then flow upward along the first connecting hole 210 to the inner ring gas passage 200.

[0046] It is understood that in some embodiments, the second connecting hole 310 on the bottom wall of the outer ring gas passage 300 is located near the groove 320. Thus, when the gas flows upward from the groove 320 to the outer ring gas passage 300, it can flow directly through the second connecting hole 310 into the inner ring gas passage 200, thereby making the gas flow smoother.

[0047] Reference Figures 1 to 6 In some embodiments, the bottom wall of the groove 320 is also provided with a downwardly recessed guide groove 330. One end of the guide groove 330 is connected to the third connecting hole 321, and the other end of the guide groove 330 is provided with a second guide surface 331. The second guide surface 331 extends from bottom to top along the direction away from the third connecting hole 321.

[0048] In the above structure, the second guide surface 331 can guide the gas flowing out from the third connecting hole 321 to flow upward along the second guide surface 331 into the groove 320, avoiding the gas from colliding directly with the outer inner wall of the groove 320 due to excessive flow velocity when flowing out from the third connecting hole 321, thus preventing airflow turbulence. This allows the gas to flow more smoothly from the air intake channel 410 into the groove 320.

[0049] It is understood that the second guide surface 331 can be an arc-shaped guide surface with the opening facing upward, or it can be a guide slope. This utility model does not make any specific limitation in this regard.

[0050] Reference Figures 1 to 6 In some embodiments, the groove 320 is an arc-shaped groove extending circumferentially along the outer ring gas passage 300. Both ends of the groove 320 are provided with a third guide surface 322, which extends from bottom to top along a direction away from the third connecting hole 321.

[0051] In the above structure, the third guide surface 322 can guide the gas to flow upward along the third guide surface 322 into the outer ring gas channel 300, avoiding the gas from flowing rapidly along the groove 320 and colliding with the two ends of the groove 320, which would cause airflow turbulence. This is conducive to guiding the gas to flow smoothly into the outer ring gas channel 300.

[0052] It is understood that the third guide surface 322 can be an arc-shaped guide surface or a guide slope, and this utility model does not specifically limit it in this regard.

[0053] Reference Figures 1 to 8 In some embodiments, the ejector tube 400 and the connecting part 500 are both connected to the bottom wall of the base 100, and the base 100, the ejector tube 400 and the connecting part 500 are integrally formed structures.

[0054] By adopting the above structure, the connection between the injector 400, the connecting part 500, and the base 100 is more robust and compact, which helps to improve the structural strength of the flame distributor and facilitates its production and manufacturing, reducing the number of parts and thus improving the production efficiency of the flame distributor. Furthermore, the base 100, injector 400, and connecting part 500 are integrally molded, which also improves the airtightness of the flame distributor and reduces the risk of gas leakage during use.

[0055] It is understood that the base 100, the ejector tube 400 and the connecting part 500 are integrally molded structures. Specifically, the base 100, the ejector tube 400 and the connecting part 500 can be integrally injection molded structures, and this utility model does not make specific limitations in this regard.

[0056] Reference Figures 1 to 8 In some embodiments, the first connecting hole 210 and the second connecting hole 310 both penetrate downward through the side wall of the connecting part 500 and are connected to the connecting channel 510. The end of the connecting part 500 away from the inner ring gas channel 200 has a machining hole that is connected to the connecting channel 510. The machining hole is coaxially arranged with the connecting channel 510, and a plug 520 is sealed and installed at the machining hole.

[0057] In the above structure, the first connecting hole 210 is formed on the bottom wall of the inner ring gas passage 200 and extends downward to the side wall of the through-connection portion 500. This not only enables communication between the inner ring gas passage 200 and the connecting passage 510 through the first connecting hole 210, but also facilitates the machining of the first connecting hole 210, which can be machined from top to bottom along the bottom wall of the inner ring gas passage 200, making machining more convenient. Similarly, the second connecting hole 310 is formed on the bottom wall of the outer ring gas passage 300 and extends downward to the side wall of the through-connection portion 500. This not only enables communication between the outer ring gas passage 300 and the connecting passage 510 through the second connecting hole 310, but also facilitates the machining of the second connecting hole 310, which can be machined from top to bottom along the bottom wall of the inner ring gas passage 200, making machining more convenient.

[0058] Furthermore, by having a machining hole at the end of the connecting part 500 away from the inner ring gas passage 200 that communicates with the connecting passage 510, and by placing a plug 520 at the machining hole, the machining of the connecting passage 510 can be facilitated. The connecting passage 510 can be formed simply by machining inward from the machining hole. After machining, the machining hole can be sealed with the plug 520. Thus, the inner ring gas passage 200 and the outer ring gas passage 300 can be connected through the connecting passage 510, and gas leakage from the machining hole can be prevented.

[0059] Reference Figure 7 and Figure 8In some embodiments, there are two connecting parts 500. The bottom wall of the inner ring gas passage 200 is provided with a first connecting hole 210 that corresponds to and communicates with each connecting passage 510, and the bottom wall of the outer ring gas passage 300 is provided with a second connecting hole 310 that corresponds to and communicates with each connecting passage 510.

[0060] In the above structure, increasing the number of connecting parts 500 can increase the number of paths for gas to flow from the outer ring gas channel 300 to the inner ring gas channel 200, so that gas can flow more smoothly from the outer ring gas channel 300 to the inner ring gas channel 200, avoiding the situation of insufficient gas in the inner ring gas channel 200.

[0061] Understandably, the number of connectors 500 is two, only for... Figure 7 and Figure 8 In addition to the illustrative example, the number of connecting parts 500 may also be three, four or more, and this utility model does not specifically limit the number of connecting parts 500.

[0062] Reference Figures 1 to 8 In some embodiments, an air passage 110 is provided between the inner ring gas passage 200 and the outer ring gas passage 300, and at least one connecting rib 120 is connected between the outer ring wall of the inner ring gas passage 200 and the inner ring wall of the outer ring gas passage 300.

[0063] In the above structure, the air passage 110 facilitates the replenishment of air for combustion in the inner ring gas passage 200 and the outer ring gas passage 300, resulting in more complete combustion and improving the combustion efficiency of the gas when the flame spreader is in use. Furthermore, the connecting rib 120 enhances the structural strength of the flame spreader and makes its structure more compact.

[0064] An embodiment of this utility model also proposes a burner, which is provided with the flame distributor of any of the above embodiments.

[0065] In the burner of this utility model embodiment, by adopting the flame distributor of any of the above embodiments, gas can be delivered to the inner ring gas passage 200 and the outer ring gas passage 300 through one ejector tube 400. Since only one ejector tube 400 is provided, only one nozzle needs to be configured for the ejector tube 400, which is more convenient to use and helps to simplify the overall structure of the burner, reduce the size of the burner, and also reduce the production and manufacturing cost of the burner.

[0066] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
