Detailed Implementation

[0023] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0024] Example 1 Please refer to Figures 1-9 This invention provides a burner, including a mixing pipe 1, a turbulence structure 7, and a first fan 21. A mixing channel is formed within the mixing pipe 1. The turbulence structure 7 is disposed within the mixing channel to turbulent the mixed airflow of fuel gas and air within the mixing channel. The first fan 21 is mounted on the mixing pipe 1, and its impeller is connected to the mixing channel to agitate the mixed airflow within the mixing channel.

[0025] The burner provided by this invention, by setting a turbulence structure 7, can disturb the gas-air mixture flow in the mixing channel, thereby improving the uniformity of gas-air mixing. Furthermore, by setting a first fan 21, the gas-air mixture flow in the mixing channel is agitated, resulting in a more uniform mixture between air and gas, thus improving the combustion efficiency of the burner.

[0026] Optionally, the turbulence structure 7 includes multiple first turbulence ribs 71, which are spaced apart on the inner wall of the mixing channel and extend along the flow direction of the airflow. When the gas and air enter the mixing pipe 1, they impact the first turbulence ribs 71 and then flow along the gaps between adjacent first turbulence ribs 71, thereby mixing the air and gas and improving the uniformity of the mixture, thus improving the combustion efficiency of the burner.

[0027] Optionally, the turbulence structure 7 further includes multiple second turbulence ribs 72. These second turbulence ribs 72 are spaced apart on the inner wall of the mixing channel and located behind the first turbulence ribs 71. The second turbulence ribs 72 extend along the airflow direction, and the first turbulence ribs 71 and second turbulence ribs 72 are staggered. When the air-fuel mixture flows through the gap between two adjacent first turbulence ribs 71 to the end of the first turbulence rib 71, it collides with the front end of the second turbulence rib 72, and then flows along the gap between two adjacent second turbulence ribs 72. This allows the air-fuel mixture to be further mixed, improving mixing uniformity and thus further improving the combustion efficiency of the burner.

[0028] Optionally, the first turbulence rib 71 and the second turbulence rib 72 are evenly distributed circumferentially along the inner wall of the mixing channel to improve the uniformity of airflow and thus improve the uniformity of mixing.

[0029] Optionally, the front end of the first bleeder rib 71 and / or the second bleeder rib 72 is provided with a first guide portion 73. The diameter of the first guide portion 73 gradually increases along the direction of airflow to guide the gas and reduce the flow resistance of the airflow.

[0030] Optionally, the gas mixing pipe 1 includes an ejector pipe 11 and a first gas mixing pipe 13. An ejector cavity 110 is provided in the ejector pipe 11, and a first gas mixing chamber 130 is provided in the first gas mixing pipe 13. A first fan 21 is installed between the ejector pipe 11 and the first gas mixing pipe 13. The air inlet of the first fan 21 is connected to the air outlet of the ejector pipe 11, and the air outlet of the first fan 21 is connected to the air inlet of the first gas mixing pipe 13. A turbulence structure 7 is provided in the ejector cavity 110 and / or the first gas mixing chamber 130.

[0031] Optionally, the blower 2 includes a housing 21 and a blower body 22. A receiving cavity 210 is formed within the housing 21, and the blower body 22 is installed within the receiving cavity 210. A first end of the housing 21 is sealed to the outlet port of the ejector pipe 11, and a second end of the housing 21 is sealed to the inlet port of the first mixing pipe 13. The ejector cavity 110 and the first mixing cavity 130 are connected through the receiving cavity 210. This allows the gas mixture of fuel gas and air in the ejector cavity 110 to enter the receiving cavity 210 when the blower body 22 rotates. Within the receiving cavity 210, the mixture is agitated by the impeller of the blower body 22, achieving gas mixing, before flowing out to the first mixing cavity 130 for further mixing.

[0032] Optionally, the gas mixing pipe 1 further includes a mixing pipe 12. The inlet port of the mixing pipe 12 is connected to the outlet port of the ejector pipe 11, and the outlet port of the mixing pipe 12 is connected to the first end of the outer casing 21. A mixing chamber 120 is formed inside the mixing pipe 12, and the receiving chamber 210 and the ejector chamber 110 are connected through the mixing chamber 120. By setting the mixing pipe 12, the air and fuel gas mixture in the ejector chamber 110 can be further mixed in the mixing chamber 120 of the mixing pipe 12 before entering the receiving chamber 210, where it is further mixed under the agitation of the impeller of the blower body 22, thereby further improving the uniformity of gas mixing.

[0033] Optionally, the ejector tube 11 extends along a first direction, and the first mixing tube 13 is arranged along a second direction, with the first and second directions perpendicular to each other. This makes the burner structure more compact, reducing structural volume and facilitating product miniaturization. It also allows the mixed gas to change direction during flow, improving the uniformity of gas mixing.

[0034] Optionally, the inner diameter of the ejector cavity 110 gradually decreases along the direction of gas flow, and the inner diameter of the mixing cavity 120 is larger than the inner diameter of the outlet port of the ejector tube 11. This allows the flow velocity of the mixed gas in the ejector cavity 110 to be increased, and diffusion to occur when it flows into the mixing cavity 120, thereby improving the uniformity of the gas mixture.

[0035] Optionally, it also includes a first mounting plate 31, which is installed at the air inlet of the first mixing pipe 13, and the outer casing 21 is installed on the first mounting plate 31, thereby realizing the installation of the fan 2 on the first mixing pipe 13.

A third mounting hole 310 corresponding to the second mounting hole 2110 is formed on the first mounting plate 31. Screws pass through the first mounting hole 1210, the second mounting hole 2110, and the third mounting hole 310 in sequence to fix the mixing tube 12, the outer shell 21, and the first mounting plate 31. This achieves the connection and installation between the mixing tube 12, the outer shell 21, and the first mounting plate 31, resulting in a simple structure, easy installation, and high installation stability.

[0037] Optionally, the first mounting plate 31 and the first mixing pipe 13 are integrally formed, which has a simple structure and can enhance the strength between the first mounting plate 31 and the first mixing pipe 13.

[0038] Optionally, the mixing tube 12 and the ejector tube 11 are integrally formed, which is simple in structure, easy to install, and has high strength.

[0039] Optionally, it also includes a nozzle 6 and a support 61. An installation part 111 is provided at the air inlet port of the ejector tube 11. The support 61 is installed on the installation part 111. The nozzle 6 is installed on the support 61. The nozzle 6 is aligned with the ejector cavity 110. The air inlet port of the nozzle 6 is connected to the gas supply pipe outside the burner.

[0040] Optionally, there are two of each of the first mixing pipe 13, the first fan 21, and the ejector pipe 11, with the two first mixing pipes 13, the two first fans 21, and the two ejector pipes 11 arranged in a one-to-one correspondence.

The outer flame cap 51 is placed on the upper side of the flame spreader body 41 and surrounds the flame spreader body 41 to form an outer ring gas cavity that communicates with the outer ring gas passage 421. The inner flame cap 52 is placed on the upper side of the flame spreader body 41 and surrounds the flame spreader body 41 to form an inner ring gas cavity that communicates with the inner ring gas passage 422. The outlet port of one first mixing pipe 13 is connected to the outer ring gas passage 421, and the outlet port of another first mixing pipe 13 is connected to the inner ring gas passage 422.

[0042] It should be noted that in this embodiment, the front and rear directions are defined by the direction of airflow. That is, the initial contact point of the airflow is the front end, and the last point through which the airflow passes is the rear end.

[0043] Example 2 Please refer to Figures 10-17 The difference between Embodiment 2 and Embodiment 1 is that the turbulence structure 7 includes a substrate 74 and a group of channels 70 formed on the substrate 74. The group of channels 70 includes multiple channels 70, some of which have different opening directions than others. The multiple channels 70 are connected to form an airflow channel, which runs through the front and rear ends of the substrate 74. When the fuel gas and air enter the mixing pipe 1, the gas enters the airflow channel 700 and mixes in the channels 70 with different directions forming the airflow channel 700, thereby making the mixing of air and fuel gas more uniform and improving the combustion efficiency of the burner.

[0044] Optionally, multiple sets of channels 70 are provided, and the multiple sets of channels 70 are evenly distributed along the radial direction of the substrate 74 to form multiple airflow channels 700, thereby improving the mixing efficiency and mixing effect of air and gas.

[0045] Optionally, the peripheral sidewall of the substrate 74 abuts against the inner sidewall of the gas mixing channel to achieve the mounting of the substrate 74 in the gas mixing channel.

[0046] Furthermore, the substrate 74 can be installed in the gas mixing channel by means of adhesive, threaded connection, etc., to enhance the connection stability between the substrate 74 and the gas mixing pipe 1.

[0047] Example 3 Please refer to Figures 18-24 The difference between Embodiment 3 and Embodiment 1 is that the turbulence structure 7 includes a base shaft 75 and multiple turbulence vanes 76 disposed on the base shaft 75. The base shaft 75 extends along the airflow direction, and the multiple turbulence vanes 76 are radially spaced around the base shaft 75. When the gas and air enter the mixing pipe 1, the gas and air collide with the front end of the base shaft 75 and the front end of the turbulence vanes 76, and then flow along the gap between adjacent turbulence vanes 76, so that the air and gas mix with each other, thereby improving the mixing uniformity between air and gas, and thus improving the combustion efficiency of the burner.

[0048] Optionally, the baffle 76 is inclined along the airflow direction; and / or the baffle 76 is radially inclined along the base axis 75 to improve the mixing effect of air and fuel, improve the uniformity of air and fuel mixing, and further improve combustion efficiency.

The diameter of the second guide section 77 gradually increases from front to back, so as to facilitate the smooth flow of air along the guide section 73 to the space between the turbulence vanes 76, thereby guiding the airflow and reducing the resistance of the base shaft 75 to the airflow.

[0051] Optionally, a second guide section 77 is provided at the rear end of the base shaft 75. The diameter of the second guide section 77 gradually decreases from front to back to facilitate the smooth flow of air from the guide section 73, which is conducive to the flow and mixing of air and gas.

[0052] Example 4 Please refer to Figures 25-28The difference between Embodiment 4 and Embodiments 1, 2 and 3 is that Embodiment 4 also includes a second fan 22, and the mixing pipe 1 also includes a second mixing pipe 14.

The air inlet of the second fan 22 is connected to the air outlet of the ejector pipe 11, and the air outlet of the second fan 22 is connected to the air inlet of the second mixing pipe 14. By setting up a second fan 22, the gas mixture of gas and air enters the ejector chamber 110 and is further mixed under the rotation of the impeller of the second fan 22, which greatly improves the uniformity of the mixture between air and gas. Then it enters the second mixing chamber 140 for further mixing. The uniformity of the mixture between air and gas is high. The mixed gas is further mixed under the rotation of the impeller of the first fan 21, thereby further improving the uniformity of the mixture between air and gas, and thus effectively improving the combustion efficiency of the burner.

The second mixing cavity 140 and the first mixing cavity 130 are connected through the first receiving cavity 2110. In this way, when the first blower body 212 rotates, the gas mixture of fuel gas and air in the second mixing cavity 140 can enter the first receiving cavity 2110, be agitated by the impeller of the first blower body 212 in the first receiving cavity 2110, achieve gas mixing, and then flow out to the first mixing cavity 130 for further mixing. The second fan 22 includes a second outer casing 221 and a second fan body 222. A second accommodating cavity 2210 is formed inside the second outer casing 221. The second fan body 222 is installed inside the second accommodating cavity 2210. The outlet port of the mixing pipe 12 is connected to the first end of the second outer casing 221. A mixing chamber 120 is formed inside the mixing pipe 12. The second accommodating cavity 2210 is connected to the ejector cavity 110 through the mixing chamber 120. In this way, when the second fan body 222 rotates, the gas mixture of gas and air in the mixing chamber 120 can enter the second accommodating cavity 2210, be agitated by the impeller of the second fan body 222 in the second accommodating cavity 2210, achieve gas mixing, and then flow out to the second mixing chamber 140 for further mixing.

[0054] Optionally, it also includes a second mounting plate 32, which is installed at the air inlet of the second mixing pipe 14, and the second housing 221 is installed on the second mounting plate 32.

[0055] Optionally, a second screw is also included. A third lug 141 is provided on the outer periphery of the second mixing pipe 14, and a fourth mounting hole 1410 is provided on the third lug 141.
