Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] like Figures 1 to 4 As shown, a novel burner head structure is provided. The burner head base 1 includes an outer burner head 2 and an inner burner head 3. The outer burner head 2 is connected to an outer ejector tube 4. The inner burner head 3 is provided with a partition plate 7 in the middle. The inner burner head 3 is provided with a central flame cap 8 with a vent hole 10 on the upper side. A gas mixing chamber 9 is provided between the central flame cap 8 and the partition plate 7.

[0032] A central ejector device 5 is provided on the lower side of the partition plate 7. The central ejector device 5 includes an inner ejector tube 503, which passes through the partition plate 7 from bottom to top and leads to the gas mixing chamber 9.

[0033] Specifically, the central ejector device 5 also includes a nozzle seat 502, an air inlet 504 on the side of the nozzle seat 502, a nozzle 501 on the upper surface of the nozzle seat 502, and an inner ejector tube 503 placed above the nozzle 501; the nozzle seat 502 is provided with an air inlet channel 505 connecting the air inlet 504 and the nozzle 501.

[0034] Furthermore, the upper surface of the nozzle seat 502 is provided with at least one nozzle 501 and leads to the gas mixing chamber 9 through at least one inner ejector tube 503; the side of the nozzle seat 502 is provided with at least one air inlet 504 and at least one air inlet channel 505, and the nozzle 501 is located on the upper side of the air inlet channel 505.

[0035] The lower end of the inner ejector tube 503 is connected to the nozzle 501, and the upper end passes through the partition plate 7 to the gas mixing chamber 9. A connecting column 6 is provided on the lower side of the inner furnace head 3, and the nozzle seat 502 is connected to the inner furnace head 3 through the connecting column 6.

[0036] Furthermore, air holes 506 are provided on both sides of the lower end of the inner ejector tube 503. When the nozzle 501 passes the gas upward, air is introduced into the inner ejector tube 503 through the air holes 506, and then the air and gas are mixed in the gas mixing chamber 9 through the inner ejector tube 503.

[0037] Furthermore, the vent holes 10 on the center burner cap 8 are arranged in a honeycomb pattern, which allows for better mixing of air and fuel gas, more uniform gas output, more complete combustion, and less combustion noise.

[0038] Furthermore, the central burner cap 8 is designed to be an inverted V-shaped burner cap 11 with the center protruding upwards. The vent 10 is located on the inverted V-shaped burner cap 11 and is perpendicular to the upper surface of the inverted V-shaped burner cap 11 to form radial vent 12 that tilts outwards. The inverted V-shaped burner cap 11 not only makes the combustion more complete, but also has an upward protrusion in the center, so that when items or liquids fall from above, they are less likely to enter the burner head, thus protecting the combustion of the burner head, and it is also easy to clean.

[0039] Furthermore, an outer ring flame cover 15 is provided on the upper side of the outer burner head 2. The outer ring flame cover 15 is an inverted V-shaped outer ring flame cover 16. A second vent hole 17 is provided on the inverted V-shaped outer ring flame cover 16. The second vent hole 17 and the upper surface of the inverted V-shaped outer ring flame cover 16 form a second radial vent hole 18 that is inclined to both sides.

[0040] The inner and outer V-shaped burner caps allow the inner burner head 3 to release gas outwards and the outer burner head 2 to release gas inwards, resulting in a more even and concentrated gas distribution and more complete combustion.

[0041] Furthermore, the inner burner head 3 is installed in the inner ring of the outer burner head 2 via the connecting plate 14 and coincides with the center of the outer burner head 2. The outer ring burner cover 15 and the center burner cover 8 are connected as a whole via the connecting plate 14.

[0042] Furthermore, the inner furnace head 3 has mounting holes 13 on its side for installing thermocouples and ignition needles.

[0043] like Figures 1 to 6As shown in the figure, this is the first embodiment of the present invention. Three nozzles 501 are provided on the upper surface of the nozzle seat 502. The three nozzles 501 are respectively connected to the gas mixing chamber 9 through three inner ejector tubes 503.

[0044] The nozzle seat 502 has two air inlet buckles 504 and two air inlet channels 505 on its side. The two air inlet channels 505 are interconnected, and the nozzle 501 is located on the upper side of the air inlet channel 505.

[0045] Through the air holes 506 on both sides of the lower end of the inner ejector tube 503, while the nozzle 501 is supplying gas upwards, air is introduced into the inner ejector tube 503 through the air holes 506, and the air and gas are mixed for the first time. Then, the air and gas are mixed for the second time in the gas mixing chamber 9 through the inner ejector tube 503. Through the two mixing processes, the air and gas form a uniform combustible mixture, thereby improving combustion efficiency.

[0046] This invention uses multiple internal ejector tubes 503 to introduce gas into the gas mixing chamber 9 on the inner furnace head 3, forming a uniform combustible gas mixture. This fully mixed gas can burn more completely, releasing more heat, improving combustion efficiency, reducing the generation of harmful gases such as carbon monoxide, reducing the risk of poisoning caused by incomplete combustion of gas, and also helping to reduce environmental pollution. The number of internal ejector tubes 503 and nozzles 501 can be adjusted according to actual conditions.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
