Description

Technical Field

[0001] This invention belongs to the field of kitchen equipment technology, specifically relating to an oxygen-assisted gas burner. Background Technology

[0002] As an indispensable cooking appliance in modern kitchens, the performance of the burner, a core component of gas stoves, directly affects combustion efficiency, energy utilization, and safety. Currently, most gas burners on the market employ atmospheric combustion, where gas is ejected and then drawn in air via an ejector mechanism, where it mixes inside the burner or at the outlet before combustion. While this traditional method is simple in structure and low in cost, its combustion process relies entirely on the natural diffusion and mixing of air in the environment, which presents certain limitations.

[0003] First, due to the passive and uncontrollable air supply, the mixing of fuel gas and air is often uneven and insufficient, especially under fire control or external airflow interference, which can easily lead to decreased combustion stability. Incomplete combustion not only reduces thermal efficiency and wastes energy, but also easily produces harmful gases such as carbon monoxide, posing safety hazards. Second, in pursuit of higher heat loads or greater firepower, it is usually necessary to increase the fuel gas flow rate or nozzle size, but this may further worsen the mixing conditions, resulting in uneven flame temperature distribution and difficulty in effectively improving thermal efficiency. Although there are some solutions in existing technologies that attempt to improve the mixing effect, such as using more complex ejector structures, multi-channel gas supply, or partial premixing designs, these solutions often complicate the burner structure, increase manufacturing and maintenance costs, and have limited effect on improving the precision of oxygen supply and the uniformity of mixing, especially making it difficult to dynamically fine-tune the oxygen-supporting ratio according to the combustion state.

[0004] Therefore, how to effectively improve the uniformity of gas and oxygen mixing and the completeness of combustion, while maintaining a relatively simple and reliable gas stove structure, to achieve more efficient, energy-saving, and environmentally friendly combustion, has become a topic worthy of in-depth research in this field. This invention is an improvement made against this background. Summary of the Invention

[0005] To solve at least one of the above-mentioned technical problems, the present invention provides an oxygen-assisted gas burner head.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] An oxygen-assisted gas-fired burner head includes:

[0008] Fire cap,

[0009] air guide cone,

[0010] Mixing disc,

[0011] Layered pipe,

[0012] Oxygen generating equipment, and

[0013] Sensing probe;

[0014] The mixing disc includes a disc bottom, a disc strip, a disc surface, and a hole seat. The disc strip consists of multiple cylindrical strips of different diameters and equal heights, arranged vertically concentrically in layers to form multiple horizontal partition layers. The disc surface is provided with disc holes, and the hole seat is used to install the sensing probe.

[0015] The layered pipe consists of two pipes, which are partially double-layered composite pipes. The inner pipe is used to transport gas, and the outer pipe is used to transport oxygen.

[0016] The oxygen generator is an independent pluggable component, which is equipped with a gas delivery pipe for connecting to the oxygen replenishment port.

[0017] The air guide cone consists of multiple conical cylinders with different outer diameters and equal heights, arranged vertically and coaxially in layers to form multiple horizontal isolation layers. The isolation layers are connected to the partition layers of the mixing disc.

[0018] The flame cap is placed on top of the gas guide cone and has a cap hole;

[0019] The sensing probe is fixed inside the hole seat and extends upward through the flame cap.

[0020] Preferably, the bottom of the mixing disc is provided with a plurality of air inlet connection holes, and the air inlet connection holes are connected to the layered pipe through branch connections.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The core of the oxygen-assisted gas burner provided by this invention lies in the introduction of a micro-oxygen generator to actively introduce a small amount and a controllable proportion of oxygen into the gas, fundamentally improving the traditional gas stove's passive combustion mode that relies solely on natural draft and mixing. This design allows the gas to undergo preliminary oxygen-enriched premixing before mixing with air, thereby significantly improving the completeness and stability of combustion, resulting in higher flame temperatures, more complete combustion, effectively improving thermal efficiency, and reducing harmful gases such as carbon monoxide produced by incomplete combustion, thus offering the dual advantages of energy saving and environmental protection.

This structure ensures uniform flame distribution from the center of the burner to the periphery, resulting in more even heating of the cookware. It also provides a basis for branch control and precise adjustment of heat, allowing users to flexibly control the heat according to their cooking needs and further avoiding energy waste.

[0031] Furthermore, the oxygen generator of this invention adopts an independent and detachable modular design, requiring no external power supply and powered by a button battery, greatly improving ease of use and product adaptability. Users can decide whether to activate the oxygen-assisting function according to actual needs, switching between normal use and high-efficiency energy-saving modes. The overall structure achieves functional innovation while maintaining reasonable complexity; each component is designed with both functionality and ease of assembly, and the integrated sensor probe ensures safety during use. In summary, this invention achieves effective improvements in combustion performance, usage control, energy efficiency, and safety and environmental protection. Attached Figure Description

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. However, the drawings are merely illustrative and do not represent a complete and exhaustive representation of the invention. In the following description, when referring to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The terms "upper," "lower," "left," "right," "inner," "outer," "front," and "rear" appearing in the description are only used to illustrate the understanding of the invention with reference to the drawings. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application; rather, they are merely examples of apparatuses or methods consistent with some aspects of this application as detailed in the appended claims.

[0043] This invention provides an oxygen-assisted gas burner head that adds an oxygen-assisted process to the traditional gas stove, resulting in more complete gas combustion and higher combustion efficiency. Figure 7 As shown in the diagram, the intervention point of the present invention can be clearly seen, namely, the introduction of oxygen with a gas ratio of <2% into the front-end facilities of a conventional burner, and the mixing and combustion by the special combustion burner of the present invention.

[0044] Specifically, the present invention provides an oxygen-assisted gas burner head, the overall structure of which is a combination of a truncated cone and a cylinder. Its upper part is a cone without a pointed tip, and its lower part is a disc-shaped base. Its side view resembles a soup bowl. (See also...) Figure 2 As shown; the furnace head includes a fire cover 1, a gas guide cone 2, a gas mixing disc 3, at least one layered pipe 4, an oxygen generating device 5, and an induction probe 6.

[0045] Furthermore, according to Figure 3 , Figure 4As shown, the main function of the mixing disc 3 is to mix gases. It consists of a disc bottom 31, a disc belt 32, a disc surface 33, and a perforated seat 34. The disc bottom 31 is a horizontally arranged circular plate. The disc belt 32 is arranged on the upper surface of the disc bottom 31. The disc belt 32 consists of multiple cylindrical belts of different diameters and equal heights. The cylindrical belts are arranged vertically concentrically in layers, forming multiple relatively independent horizontal partition layers. These partition layers allow the fuel gas and oxygen to be fully mixed and output upwards. The outermost belt has an outer diameter that is the same as the... The outer diameter of the bottom plate 31 is the same; the plate surface 33 is located on the top of the belt 32, and its shape and size are the same as those of the bottom plate 31. The plate body of the plate surface 33 is provided with plate holes 331 according to the belt spacing of the belt 32. The plate holes 331 are arranged in a ring at equal intervals; the hole seat 34 is located at the center of the mixing plate 3. The hole seat 34 includes two holes for installing and fixing the sensing probe 6; an air inlet connection hole is also reserved on the plate body of the bottom plate 31, that is, under each partition layer.

[0046] Furthermore, in this invention, the layered pipe 4 is preferably two pipes, each with a corresponding connecting assembly including a valve hole sleeve 41 and a branch connector 42; as shown Figure 3 , Figure 6 As shown, the layered pipe 4 is a partially double-layered composite pipe. Its inner layer is a gas supply pipe, connected to the gas supply via an external component; its outer layer is an oxygen supply pipe, connected to an oxygen supply facility via an external pipeline or directly. A valve orifice sleeve 41 is provided at the critical point of the single / double-layered composite pipe. The valve orifice sleeve 41 is a sealing head for the outer pipeline, constructed as a conical body with an outer end diameter larger than the inner end diameter. The inner end is threadedly connected to the outer pipe. Tightening the inner end compresses the inner part of the outer end, causing the internal rubber gasket to tightly wrap around the inner pipe. An oxygen replenishment hole is provided on the end face of the outer end of the valve orifice sleeve 41. This oxygen replenishment hole is a one-way check valve, remaining normally closed when no external oxygen supply facility is connected.

[0047] There are two branch connectors 42, namely a front branch connector 421 and a rear branch connector 422, arranged in a straight line in front and behind. They are pipe connection fittings and are located at the bottom of the mixing plate 3. Each branch connector 42 consists of a horizontal air inlet and multiple vertical air outlets. The air inlet is fixedly connected to one end of the layered pipe 4, and the air outlets are fixedly connected to the air inlet connection holes reserved on the plate bottom 31. Preferably, the air outlets are arranged in a staggered manner according to the interval layer set in the plate 32. The multiple air outlets of the front branch connector 421 are connected to the odd-numbered air inlet connection holes on the plate bottom 31, and the multiple air outlets of the rear branch connector 422 are connected to the even-numbered air inlet connection holes on the plate bottom 31, thereby realizing staggered air supply. Its main function is to evenly distribute the air supply into two paths and control them separately to achieve uniform flame, energy saving and consumption reduction, and adjustment of firepower.

[0048] Furthermore, refer to Figure 5 As shown, the gas guide cone 2 consists of multiple conical cylinders with different outer diameters and equal heights. The conical cylinders are arranged vertically and coaxially in layers to form multiple relatively independent horizontal isolation layers. These isolation layers correspond to and are fixedly connected to the partition layer of the gas mixing disk 3, allowing the gas mixed in the partition layer to enter the isolation layer along the disk hole 331 for uniform diffusion. The outermost conical cylinder has the same bottom outer diameter as the disk surface 33. The gas guide cone 2 and the gas mixing disk 3 are preferably integrally cast.

[0049] Furthermore, such as Figure 6 As shown, the flame cap 1 is an independent movable component, placed on top of the gas guide cone 2. The flame cap 1 is disc-shaped, and its bottom, corresponding to the top of the gas guide cone 2, has multiple circular grooves. These grooves serve to fix the cap and isolate the gas. Multiple rings of cap holes 11 are arranged in a matrix with the center of the cap as the radius. The diameter of each cap hole 11 is less than the diameter of the disc hole 331. There are at least two rings of cap holes 11 within each circular groove corresponding to the gas guide cone 2 to achieve uniform flame output. Two through holes are pre-drilled in the groove at the center of the flame cap 1, corresponding to the vertically downward hole seat 34, for orienting the flame cap 1 and covering the induction probe 6.

[0050] Furthermore, through Figure 2 , Figure 4 , Figure 5 and Figure 6It is understood that the sensing probe 6 consists of two extended sensing probes, namely an ignition needle and a flameout protection needle; the bottom of the sensing probe 6 is fixedly installed in the hole seat 34 of the mixing plate 3, the top of the sensing probe 6 is naturally vertical and is positioned and covered by the flame cap 1, and the top of the sensing probe 6 is slightly higher than the upper surface of the flame cap 1; the connecting wire of the sensing probe 6 is output externally through the bottom of the hole seat 34.

[0051] Furthermore, such as Figure 6 As shown, the oxygen generating device 5 is an independent accessory, and its connection can be determined independently. The oxygen generating device 5 is a cylindrical miniature oxygen generating facility, and its oxygen generation capacity accounts for 0.5%-2% of the total gas delivery capacity of this invention. It is equipped with a replaceable button battery at its tail end, which can generate oxygen generation kinetic energy through the built-in button battery without the need for an external power supply. The oxygen generating components are located inside its column. Two gas delivery pipes are provided on its top end face, and the gas delivery pipes are inserted into the oxygen replenishment holes on the valve hole sleeves 41 of the two layered pipes 4.

[0052] Furthermore, by combining the present invention with external components, the practical application effect of the present invention can be demonstrated, as can be seen from the following: Figure 1 As shown, the Figure 1 The schematic diagrams shown are only intended as inspiration for practical applications of the present invention.

[0053] The working steps and working principle of this invention are as follows:

[0054] The gas is transported through the inner layer of the layered pipe 4. If the oxygen generator 5 is connected, the trace amount of oxygen produced by it is simultaneously transported through the outer layer. After the gas and oxygen converge at the end of the layered pipe 4, they are distributed to different partition layers of the mixing disc 3 through the branch connector 42 for preliminary mixing. The mixed gas rises through the disc holes 331, enters the partition layer corresponding to the gas guide cone 2 for uniform distribution, and finally is ejected from the densely packed cap holes 11 on the burner cap 1 and ignited. The induction probe 6 ensures the safety of the ignition process and use. By using the front branch connector 421 and the rear branch connector 422 to distribute the gas flow path, the firepower of different combustion zones of the burner head can be effectively adjusted and controlled separately, thereby achieving the purpose of energy saving and precise firepower control.

[0055] The specific embodiments of the present invention have been described in detail above, but they are only examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this invention are also within the scope of the present invention. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
