DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] The invention provides a gas-saving high-fire burner head, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes a burner body 1, a furnace cavity 11 is formed in the burner body 1, a gas mixing pipe 12 is integrally connected to the burner body 1, an air outlet 111 is formed at the upper end of the furnace cavity 11, the lower end of the furnace cavity 11 is connected to one end of the gas mixing pipe 12, and the other end of the gas mixing pipe 12 is connected to the gas inlet pipe 41 and the compressed air inlet pipe 42. Specifically, the other end of the gas mixing pipe 12 is formed with a three-way structure 121, and the gas inlet pipe 41 and the compressed air inlet pipe 42 are connected to the gas mixing pipe 12 through the three-way structure 121. Figure 1 As shown, a gas permeable damping structure 3 is provided in the furnace cavity 11, and the furnace cavity 11 may be a circular cavity (or a rectangular or elliptical cavity, etc.), and a fire cover 2 is provided at the gas outlet 111, and the fire cover 2 is provided on the upper side of the gas permeable damping structure 3, and a flame hole 201 is formed on the fire cover 2, and the gas mixing pipe 12 is connected to the flame hole 201 through the gas permeable damping structure 3, and a supporting step may be formed on the inner side of the gas outlet 111, and the supporting step supports the edge of the fire cover 2, which is conducive to the positioning and stable placement of the fire cover 2. After the combustible mixed gas (air and gas mixture) flows through the gas permeable damping structure 3, it can be discharged upward through the flame hole 201.

[0023] The working principle of the fierce fire burner of the present invention is briefly described below: Figure 1 and Figure 2As shown, the gas inlet pipe 41 is connected to a gas source (for example, 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 an air compressor, so that the compressed air and the gas are injected into the mixing pipe 12 at the same time. Through the flushing effect of the compressed air, the compressed air and the gas are violently mixed in the mixing pipe 12, so that the compressed air and the gas are well mixed in advance, and because the air is actively pressurized and mixed, it is beneficial to have sufficient oxygen content in the combustible mixed gas; the combustible mixed gas flows through the mixing pipe 12, and the combustible mixed gas then reaches the furnace cavity 11 and passes through the air-permeable damping structure 3, igniting the combustible mixed gas discharged from the flame hole 201, and forming a flame. Due to sufficient oxygen, the gas can be fully burned, and because the air-permeable damping structure 3 reduces the discharge speed of the combustible mixed gas, the height of the flame spraying upward is lower (the performance when the cooker is taken away), and the flame is increased. When the bottom of the pot is heated, relatively less heat energy is lost to the outside, but more heat energy can be transferred to the bottom of the pot. Although the burner head of the fierce fire stove in the prior art does not inject compressed air, the gas flow is large and the flow rate is fast, so the flame is ejected at a fast speed and a long range, causing the heat attached to the hot air flow to quickly diffuse outward along the bottom of the pot and eventually lose to the outside, and the heat energy that can be effectively transferred to the bottom of the pot is relatively small, which means that excessive gas output and improper air ratio cause gas waste. Therefore, although the flame of the fierce fire stove in the prior art is more fierce, it is actually less energy efficient and also causes the room temperature in the kitchen to be too high. In contrast, the fierce fire burner head of the present invention is conducive to the gas and air to fully exert the most reasonable combustion effect under certain conditions and is conducive to the effective use of heat energy, so it is conducive to saving gas. As gas prices continue to rise, saving gas is conducive to reducing the operating costs of the catering industry.

[0024] The fierce fire stove head of the present invention uses compressed air to improve the mixing ratio of gas and air, and is provided with a breathable damping structure 3 to prevent the flame from being ejected quickly, which not only achieves a good combustion effect, but also facilitates the effective use of heat energy. After actual tests, under the same condition of boiling 20 kg of water, the existing fierce fire stove takes about 30 minutes and consumes about 350 grams of liquefied petroleum gas, while the fierce fire stove provided with the fierce fire stove head of the present invention only takes about 21 minutes and consumes only about 250 grams of liquefied petroleum gas. It can be seen that the fierce fire stove head of the present invention is conducive to saving gas and saving cooking time.

[0025] Furthermore, if Figure 1 As shown, the breathable damping structure 3 includes a damping mesh 31, which can be a steel mesh formed with fine mesh holes. The damping mesh 31 can be arranged in multiple layers, and the mesh diameter can be 0.3 mm to 0.5 mm; the damping mesh 31 can also be composed of stainless steel wires wound in an irregular manner; the above-mentioned breathable damping structure 3 is easy to obtain and has a low cost.

[0026] Furthermore, if Figure 1 As shown, the breathable damping structure 3 includes damping particles 32, which are arranged between the upper and lower layers of the damping net 31. The damping particles 32 can be ceramic particles, sand particles or steel particles that will not be ignited by flames (in a non-pure oxygen environment). The damping particles 32 can make the path of the combustible mixed gas circuitous, effectively reducing the flow rate of the combustible mixed gas.

[0027] Furthermore, the damping particles 32 are sand particles, which are easy to obtain and have 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 air-permeable damping structure 3 may be only a damping mesh 31 or only damping particles 32 .

[0029] Furthermore, if 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. 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 the gas flow rate. The gas regulating valve 411 and the air regulating valve 421 are respectively provided with regulating hand wheels. Therefore, by manually rotating the regulating hand wheel corresponding to the gas regulating valve 411, the valve ball of the gas regulating valve 411 can be driven to rotate, thereby regulating the gas flow rate. By rotating the regulating hand wheel corresponding to the air regulating valve 421, the compressed air flow rate can be adjusted, thereby adjusting the mixing ratio of gas and air, and also adjusting the firepower.

[0030] In some embodiments, Figure 3 As shown, the fierce fire burner of the present invention also includes a driving gear 5 for driving the gas regulating valve 411 and the air regulating valve 421 for synchronous regulation. The gas regulating valve 411 is provided with a gas regulating gear 412, and the air regulating valve 421 is provided with an air regulating gear 422. The driving gear 5 is meshed and connected with the gas regulating gear 412 and the air regulating gear 422. During the period, the gas regulating valve 411 and the air regulating valve 421 can be ball valves; therefore, when the driving gear 5 is rotated, the driving gear 5 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, so that the flow of gas and compressed air can be synchronously regulated, that is, rotating the driving gear 5 can realize the adjustment of the firepower, which is conducive to the convenient use of the fierce fire burner; at the compressed gas source end, a pressure regulating valve for adjusting the output pressure of compressed air can be provided to adjust the mixing ratio of compressed air and gas to achieve the most preferred effect.

[0031] Furthermore, if Figure 3As shown, the high-fire burner head of the present invention also includes a driving handle 51, which is coaxially positioned relative to the driving gear 5, that is, the rotation axis of the driving handle 51 coincides with the rotation axis of the driving gear 5. Specifically, a fixed rotation support shaft can be provided on the outer wall of the mixing tube 12, and the driving gear 5 is rotatably provided on the above-mentioned rotation support shaft. The driving handle 51 can be rotatably provided on the above-mentioned rotation support shaft, and the lower end of the driving handle 51 can be welded to the upper end surface of the driving gear 5, so that rotating the driving handle 51 can drive the driving gear 5 to rotate, thereby facilitating operation.

[0032] In some embodiments, Figure 5 As shown, the air-permeable damping structure 3 is a concentric ring structure, that is, the number of the air-permeable damping structure 3 is at least two rings. Figure 5 Taking the example of the air-permeable damping structure 3 as three rings, the flame-spraying holes 201 are distributed in concentric circles. The above arrangement is conducive to the generation of concentric ring flames and uniform firepower.

[0033] The fierce fire burner head of the present invention further comprises an ignition structure, which is used to ignite the combustible mixed gas output from the flame hole 201. Since the ignition structure is a prior art and not the focus of the present invention, it will not be described in detail.
