[0002] Currently, high-powered stoves are generally used in the commercial sector and have a large power output. These stoves draw air into the burner head through a negative pressure generated by the high-speed flow of combustion gas. In other words, the inlet of the gas pipe is an open structure, allowing air and combustion gas to mix naturally within the pipe. However, due to the large flow rate of combustion gas, this natural air intake method results in insufficient oxygen intake and poor air-gas mixing, failing to achieve maximum combustion efficiency and causing gas waste. Therefore, the existing high-powered stove head technology needs improvement. Summary of the Invention

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] The gas-saving high-powered stove head proposed in this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the furnace includes a burner body 1, within which a furnace cavity 11 is formed. A mixing pipe 12 is integrally connected to the burner body 1. An outlet 111 is formed at the upper end of the furnace cavity 11, and the lower end of the furnace cavity 11 is connected to one end of the mixing pipe 12. The corresponding other end of the mixing pipe 12 is connected to a gas inlet pipe 41 and a compressed air inlet pipe 42. Specifically, a three-way structure 121 is formed at the corresponding other end of the mixing pipe 12, through which the gas inlet pipe 41 and the compressed air inlet pipe 42 are connected to the mixing pipe 12. Figure 1 As shown, a permeable damping structure 3 is provided inside the furnace cavity 11. The furnace cavity 11 can be a circular cavity (or a rectangular or elliptical cavity, etc.). A flame cap 2 is provided at the gas outlet 111, which is located on the upper side of the permeable damping structure 3. A flame nozzle 201 is formed on the flame cap 2. The gas mixing pipe 12 is connected to the flame nozzle 201 through the permeable damping structure 3. A supporting step can be formed on the inner side of the gas outlet 111. The supporting step supports the edge of the flame cap 2, which is beneficial for the positioning and stable placement of the flame cap 2. The combustible gas mixture (a mixture of air and fuel gas) flows through the permeable damping structure 3 and is discharged upward through the flame nozzle 201.

[0023] The working principle of the high-powered stove head of this utility model is briefly explained below: Figure 1 and Figure 2As shown, the gas inlet pipe 41 is connected to a gas source (e.g., bottled liquefied petroleum gas), and the compressed air inlet pipe 42 is connected to a compressed air source such as a high-pressure blower or air compressor. Compressed air and gas are then simultaneously injected into the mixing pipe 12. Through the scouring action of the compressed air, the compressed air and gas are vigorously mixed in the mixing pipe 12, ensuring good pre-mixing. Furthermore, since the air is actively pressurized and mixed in, the oxygen content in the combustible mixture is sufficient. The combustible mixture flows through the mixing pipe 12 and then reaches the furnace chamber 11, passing through the permeable damping structure 3. This ignites the combustible mixture discharged from the flame nozzle 201, forming a flame. Due to the sufficient oxygen, the gas can burn completely. Moreover, because the permeable damping structure 3 reduces the discharge speed of the combustible mixture, the flame is ejected at a lower height (as seen when removing the cookware). The flame heats... When the gas is heated to the bottom of the pot, relatively little heat is lost to the outside, and more heat is transferred to the bottom of the pot. Although the burner of the existing high-powered stove does not inject compressed air, the large flow rate and high velocity of the gas result in a faster flame speed and longer range. This causes the heat carried by the hot gas to quickly diffuse outward along the bottom of the pot and eventually be lost to the outside. Relatively little heat is effectively transferred to the bottom of the pot. This means that excessive gas output and improper air-gas ratio lead to gas waste. Therefore, although the flame of the existing high-powered stove is more intense, its energy efficiency is actually lower, and it also leads to excessively high kitchen temperatures. In contrast, the high-powered burner of this invention allows the gas to fully combine with the air under certain conditions to achieve the most reasonable combustion effect and promotes efficient heat utilization. This helps to save gas. With the continuous rise in gas prices, saving gas helps to reduce the operating costs of the catering industry.

[0024] This utility model's high-powered burner head utilizes compressed air to perfect the mixing ratio of fuel gas and air, and incorporates a breathable damping structure 3 to prevent rapid flame ejection, achieving both excellent combustion and efficient heat utilization. Actual testing showed that, when boiling 20 kg of water, existing high-powered burners take approximately 30 minutes and consume about 350 grams of liquefied petroleum gas (LPG), while the burner head of this utility model takes only about 21 minutes and consumes only about 250 grams of LPG. Therefore, this utility model's high-powered burner head effectively saves fuel and cooking time.

[0025] Furthermore, such as Figure 1 As shown, the breathable damping structure 3 includes a damping mesh 31, which can be a steel mesh with fine mesh holes. The damping mesh 31 can be arranged in multiple layers, and the mesh hole diameter can be 0.3 mm to 0.5 mm. The damping mesh 31 can also be formed by randomly stacking stainless steel wires. The above-mentioned breathable damping structure 3 is easy to obtain and has a low cost.

[0026] Furthermore, such as Figure 1 As shown, the breathable damping structure 3 includes damping particles 32, which are disposed between the upper and lower damping meshes 31. The damping particles 32 can be ceramic particles, sand particles, or steel particles that will not be ignited by flame (in a non-pure oxygen environment). The damping particles 32 can make the path of the combustible gas mixture detour, effectively reducing the flow rate of the combustible gas mixture.

[0027] Furthermore, the damping particles 32 are sand particles, which are easy to obtain and have a low cost. The diameter of the sand particles can be about 1 mm to 2 mm.

[0028] like Figure 6 As shown, in some embodiments, the breathable damping structure 3 may be only a damping mesh 31 or only damping particles 32.

[0029] Furthermore, such as Figure 2 As shown, a gas regulating valve 411 is provided on the gas inlet pipe 41, and an air regulating valve 421 is provided on the compressed air inlet pipe 42. Both the gas regulating valve 411 and the air regulating valve 421 can be ball valves or other valves in the prior art that can effectively regulate gas flow. The gas regulating valve 411 and the air regulating valve 421 are respectively provided with regulating handwheels. By manually rotating the regulating handwheel corresponding to the gas regulating valve 411, the valve ball of the gas regulating valve 411 can be rotated, thereby regulating the gas flow. By rotating the regulating handwheel corresponding to the air regulating valve 421, the compressed air flow can be regulated, thereby adjusting the mixing ratio of gas and air and also adjusting the flame intensity.

[0030] In some embodiments, such as Figure 3 As shown, the high-powered stove head of this utility model also includes a drive gear 5 for synchronously adjusting the gas regulating valve 411 and the air regulating valve 421. The gas regulating valve 411 is equipped with a gas regulating gear 412, and the air regulating valve 421 is equipped with an air regulating gear 422. The drive gear 5 meshes with the gas regulating gear 412 and the air regulating gear 422. Both the gas regulating valve 411 and the air regulating valve 421 can be ball valves. Therefore, when the drive gear 5 rotates, it simultaneously drives the gas regulating gear 412 and the air regulating gear 422 to rotate. The gas regulating gear 412 drives the valve ball of the gas regulating valve 411 to rotate, and the air regulating gear 422 drives the valve ball of the air regulating valve 421 to rotate. This allows for synchronous adjustment of the flow rates of gas and compressed air. In other words, rotating the drive gear 5 can adjust the firepower, which is beneficial for the convenient use of the high-powered stove head. At the compressed air source end, a pressure regulating valve can be installed to adjust the output pressure of the compressed air, thereby adjusting the mixing ratio of compressed air and gas to achieve the optimal effect.

[0031] Furthermore, such as Figure 3As shown, the high-powered stove head of this utility model also includes a drive handle 51. The drive handle 51 and the drive gear 5 are coaxially positioned relative to each other, that is, the rotation axis of the drive handle 51 coincides with the rotation axis of the drive gear 5. Specifically, a fixed rotation support shaft can be provided on the outer wall of the mixing pipe 12. The drive gear 5 is rotatably mounted on the aforementioned rotation support shaft. The drive handle 51 can be rotatably mounted on the aforementioned rotation support shaft. The lower end of the drive handle 51 can be welded to the upper end face of the drive gear 5. Thus, rotating the drive handle 51 can drive the drive gear 5 to rotate, thereby facilitating operation.

[0032] In some embodiments, such as Figure 5 As shown, the breathable damping structure 3 is a concentric ring structure, meaning that the number of breathable damping structures 3 is at least two rings. Figure 5 For example, the number of breathable damping structures 3 is three rings, so the flame holes 201 are distributed in concentric circles. The above arrangement is conducive to generating concentric ring flames and to uniform firepower.

[0033] The high-powered stove head of this utility model also includes an ignition structure, which is used to ignite the combustible gas mixture output from the flame hole 201. Since the ignition structure is existing technology and is not the focus of this utility model, it will not be described in detail.
