Description

Technical Field

[0001] This utility model relates to the technical field of gas stove accessories, specifically a gas burner head. Background Technology

[0002] As a core component of gas stoves, the gas burner's structural design directly affects combustion efficiency, energy consumption, and safety. With the full implementation of 3C certification in the Chinese cooking stove industry, medium-pressure self-suction commercial stoves have had to be phased out of the market. Traditional low-pressure self-suction wok stoves, due to their low heat output, cannot meet the heat requirements of businesses, causing inconvenience for users accustomed to these stoves. Therefore, creating a self-suction stove that can replace medium-pressure stoves has become an urgent task for researchers. After a year of experimentation and research, a high-power gas burner adapted to low-pressure gas has been developed. It can be used alone or in combination according to power requirements. It can be widely used in self-suction wok stoves, large pot stoves, clay pot stoves, and low-soup stoves, greatly facilitating the selection by businesses. Therefore, we have proposed a new type of gas burner. Utility Model Content

[0005] A gas burner head includes a cylinder, a base, and a flame distribution cap;

[0006] The bottom of the cylinder is equipped with a base, and the flame spreader is installed in the inner cavity of the cylinder, forming a mixed gas passage. The flame spreader includes flame spreader fins and heat sinks. A connecting seat is provided in the middle of the flame spreader fins, and the flame spreader fins are axially distributed with the connecting seat as the center.

[0007] The side of the flame spreader facing the gas source is provided with a sloping surface; the other end of the flame spreader is provided with a heat sink, which is tightly set on the inner wall of the cylinder.

The adjusting bolt is screwed inward onto the telescopic fin, and the telescopic length of the telescopic fin can be adjusted by turning the adjusting bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention achieves the firepower of traditional medium-pressure stoves, while also boasting a long lifespan and easy maintenance. Laboratory testing shows its efficiency reaches national standard level one; it is energy-saving and gas-efficient. Not only does it meet national energy conservation and environmental protection requirements, but it is also conducive to widespread adoption and has a very broad market prospect.

[0012] The "funnel effect" formed by the conical hollow structure of the base and the metal mesh accelerates the premixing of gas and primary air; the sloping surface of the flame spreader enhances the airflow turbulence effect, making combustion more complete and improving thermal efficiency; at the same time, the carbon monoxide emission concentration is far below the safety limit, making it more environmentally friendly and safe.

[0013] The combination of telescopic wings and adjusting bolts allows for different length adjustments to adapt to different gas sources. The universal threaded hole design of the connector allows for compatibility with various gas sources such as natural gas and liquefied petroleum gas by changing nozzles of different orifice diameters, meeting the needs of different scenarios such as home and commercial use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example:

[0023] Please see Figure 1-5 This utility model provides a technical solution for a gas burner head:

[0024] A gas burner head includes a cylinder 1, a base 2, and a flame distribution cover 3; the base 2 is installed at the bottom of the cylinder 1, the base 2 is conical, the base 2 is hollow, and an air intake channel is opened in the middle.

[0025] The ignition cover 3 is installed in the inner cavity of the cylinder 1, and the enclosed space is the mixing gas passage; the ignition cover 3 includes ignition fins 4 and heat sink 5, and a connecting seat is provided in the middle of the ignition fins 4, and the ignition fins 4 are axially distributed with the connecting seat as the center.

[0026] The side of the flame spreader 4 facing the gas source is provided with a sloping surface; the other end of the flame spreader 4 is provided with a heat sink 5, which is tightly set on the inner wall of the cylinder 1; a telescopic fin 6 is movably inserted into the heat sink 5, and an adjusting bolt 7 is installed at the end of the heat sink 5 away from the telescopic fin 6, and the adjusting bolt 7 is screwed inward onto the telescopic fin 6. The telescopic length of the telescopic fin 6 can be adjusted by turning the adjusting bolt 7, so as to adapt to different usage scenarios.

[0027] The cylinder 1 adopts a double-layer structure, with the inner layer being a high-temperature resistant ceramic coating and the outer layer being a high-temperature resistant metal material;

[0028] The hollow areas of the base 2 are all equipped with honeycomb metal mesh, which makes the air intake channel form a funnel effect, accelerating the premixing of air and gas; and effectively preventing the influence of external air disturbance.

[0029] The slope of the flame spreader 4 enhances the gas turbulence effect, making the flame root more stable;

[0030] A rotary knob is added to the end of the adjusting bolt 7. The surface of the knob is pressed with anti-slip texture. The adjustment range is set such that each rotation corresponds to a 2mm extension / retraction amount, which can achieve precise adjustment and adapt to different gas source scenarios.

[0031] The gas ejected from the nozzle mixes with air. Under the pressure of the gas, the mixture rises through the mixing channel to the burner cap 3, where it ignites. Due to the resistance of the burner cap 3, the upward airflow velocity and combustion velocity reach equilibrium, and the flame adheres to the burner fins 4 for combustion. The heat from the burner fins 4 diffuses into the air through the heat sink 5 and the circular tube 1, thereby reducing the operating temperature of the burner fins and extending their service life. Because the burner cap 3 has a larger gap than traditional burner caps, the resistance is lower, the flow rate is faster, and the airflow per unit time is greater, resulting in higher power. The sloping design of the burner fins 4, wider at the top and narrower at the bottom, not only reduces airflow resistance but also ensures stable combustion. The design of the heat sink 5 reduces the heat accumulation on the burner fins 4, extending their service life.

[0032] Working principle:

[0033] This gas burner head achieves efficient mixing of gas and air, stable combustion, and precise heat utilization through a scientific structural design. After the gas is ejected from the nozzle at the center of the connecting seat, it first comes into contact with the air drawn in by the base 2. The base 2 forms a "funnel effect," which accelerates airflow through Bernoulli's principle, allowing the gas and primary air to complete preliminary mixing before entering the cylinder 1. The honeycomb mesh structure ensures stable air intake while avoiding uneven mixing caused by airflow disturbance.

[0034] As the premixed gas flows upward, it is divided into multiple airflows by the flame spreader fins 4 of the flame spreader cap 3. The sloping surface of the flame spreader fins 4 causes the airflow to form turbulence, which enhances the mixing effect, provides sufficient oxygen for complete combustion, and significantly reduces carbon monoxide emissions. After the mixed gas is ignited at the end of the flame spreader fins 4, the flame adheres to the flame spreader fins 4 and burns.

[0035] like Figure 5 As shown, the flame spreader 3 of this design also has three-wing and four-wing configurations. Compared with the three-wing and four-wing configurations, the five-wing flame spreader (such as...) Figure 3 , 4 The one shown is the largest in diameter. The diameter of the four-winged flame spreader is smaller than that of the five-winged flame spreader, and the diameter of the three-winged flame spreader is smaller than that of the four-winged flame spreader. When using them, they can be combined in pairs. For example, two four-winged flame spreaders can be used together symmetrically, while three or four three-winged flame spreaders can be used together to effectively increase the firepower of the combustion.

[0036] When it is necessary to adapt to different air sources, the extension length of the telescopic fin 6 can be adjusted by rotating the adjusting bolt 7.
