Description

Technical Field

[0001] This invention relates to the field of stove head technology, specifically a novel stove head with an integrated gasification chamber. Background Technology

[0002] As a core component of kitchen cooking equipment, the burner's combustion efficiency and safety directly impact the user experience and energy costs. Existing combustion technology, especially for fuel systems requiring gasification, generally suffers from inadequate fuel handling mechanisms. Traditional burners often lack effective preheating, gasification, and deep mixing structures. Fuel typically enters the combustion zone directly in liquid or coarse atomized form, preventing fuel molecules from fully contacting and merging with combustion air before combustion. This uneven mixing directly limits the oxidation reaction rate, often resulting in incomplete calorific value release and low flame temperature, failing to meet the demands of efficient and energy-saving cooking.

[0003] Furthermore, existing technologies have significant shortcomings in fluid control and structural protection. On the one hand, traditional air supply and injection structures are relatively simple, making it difficult to utilize the fluid's own kinetic energy to create an effective negative pressure entrainment effect. This results in insufficient secondary air supply to the core combustion area, further restricting the improvement of combustion efficiency. On the other hand, existing equipment typically lacks a dedicated structure for receiving and secondary processing liquid residues generated during incomplete vaporization or injection. This leads to the easy accumulation of liquid fuel inside the burner head, causing oil circuit blockages, and in some cases, even overflowing the casing. Blockages cause abnormal combustion in the stove, and fuel overflow not only results in direct energy waste but also easily contaminates the stove surface and can even cause fires and other safety hazards. Therefore, how to achieve efficient fuel vaporization, thorough premixing, and effective overflow protection through structural optimization has become a pressing technical problem to be solved in this field. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel integrated gasification chamber burner head, which solves the technical problems in existing technologies, such as low combustion chemical reaction rate and low flame temperature due to insufficient fuel gasification premixing, and the safety hazards and resource waste caused by the easy overflow of ungasified fuel due to the lack of an effective receiving structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel integrated gasification chamber furnace head, comprising: The inner oil receiving plate has a combustion chamber cavity fixedly connected to its bottom. An ignition needle mounting hole and a fire protection needle mounting hole are provided inside the combustion chamber cavity, and one end of the ignition needle mounting hole and the fire protection needle mounting hole extends through into the interior of the inner oil receiving plate. The distributor base has a bottom fixedly connected to the center of the oil receiving inner plate, and a distributor is fixedly connected to the top of the distributor base. An air intake structure is provided on the outer wall of the distributor. An integrated air and fuel device is located on one side of the ignition distributor, and a mixing structure is provided between the integrated air and fuel device and the ignition distributor; The inner wall of the burner fixing cover is fixedly connected to the outer wall of the burner. The outer wall of the burner has a fuel injection hole, the inner wall of the burner fixing cover has an L-shaped groove, and the outer wall of the burner fixing cover has an ejection hole. The fuel injection hole, the L-shaped groove and the ejection hole of the inner wall of the burner fixing cover are connected to each other.

[0006] Preferably, the air intake structure includes a second air outlet inside the burner, a first air inlet on the bottom outer wall of the combustion chamber, a first air outlet on the top of the oil receiving inner plate, a central air intake chamber inside the combustion chamber, and the burner located at the top of the central air intake chamber.

[0007] Preferably, the mixing structure includes a vaporization chamber cover, which is located on the outer wall of the fire distributor. A vaporization chamber middle cover is fixedly connected to the inner wall of the vaporization chamber cover, and a vaporization chamber sealing layer with a fixing plate is fixedly connected to the bottom of the vaporization chamber cover.

[0008] Preferably, the air and fuel integrated device penetrates the gasification chamber cover and extends to the inner wall of the gasification chamber top cover, a sealing ring is provided between the gasification chamber top cover and the gasification chamber cover, and a mixed gas outlet is provided on the surface of the gasification chamber cover.

[0009] Preferably, a wind direction ring is fixedly connected to the bottom of the gasification chamber sealing layer with fixed plate, the wind direction ring is located on the outer wall of the combustion chamber cavity, and a bracket is also fixedly connected to the bottom of the gasification chamber sealing layer with fixed plate.

[0010] Preferably, the gasification chamber cover is connected to the top of the integrated air and fuel device, and the surface of the integrated air and fuel device has three parallel feed holes and an air outlet, a fuel inlet and an air inlet cover. The three parallel feed holes are the fuel inlet and the air inlet, respectively.

[0011] Preferably, the air inlet, air outlet, and air inlet cover are connected but not connected to the fuel inlet. The fuel inlet is connected to the fuel inlet, and the air inlet and fuel inlet on the surface of the integrated air and fuel device are vertically distributed.

[0012] Preferably, a fuel outlet is fixedly connected to the bottom of the gasification chamber cover, and a U-shaped tube is fixedly connected to the inner wall of the fuel outlet. One end of the U-shaped tube is connected to the gasification chamber cover, and the other end of the U-shaped tube is connected to the interior of the flame distributor.

[0013] Preferably, the second air outlet inside the ignition distributor is not connected to the fuel injection hole, and the two are vertically distributed.

[0014] This invention provides a novel integrated gasification chamber burner head. It has the following beneficial effects: 1. This invention achieves efficient fuel gasification and deep premixing through a unique flow channel design. Although the fuel inlet and air inlet of the integrated air and fuel device are physically isolated from each other, they maintain the same flow direction when entering the input area inside the gasification chamber. This design ensures the uniformity of the flow field from the source. During the heating process in the gasification chamber, the internal fuel rapidly transforms from a liquid to a gaseous state. Due to the increased intermolecular distance, the gaseous fuel can achieve deep molecular-level fusion with the synchronously input air. Compared to traditional technologies, this thorough premixing greatly enhances the chemical reaction rate, resulting in more complete combustion and a significantly higher flame combustion temperature than that of ordinary liquid fuel combustion.

[0015] 2. This invention significantly improves air mixing efficiency by utilizing fluid dynamics principles. High-temperature gas, accelerated by a U-tube, is ejected at high speed from fuel nozzles on the side of the burner. This high-speed jet generates a significant siphon effect in the area surrounding the burner. This effect utilizes the resulting negative pressure environment to actively entrain surrounding air into the main airflow for secondary mixing. This secondary oxygenation process before ejection effectively compensates for potential oxygen deficiency in single-stage mixing, further improving combustion efficiency and ensuring flame intensity and stability.

[0016] 3. This invention solves the problems of fuel spillage and waste through structural optimization of the inner wall of the fixed shroud. The inner wall of the fixed shroud features a grooved surface structure, which effectively catches any residual or incompletely vaporized fuel droplets that may remain during injection, trapping them within the core combustion area. Utilizing the high-temperature environment generated by combustion, the droplets trapped in the groove undergo secondary heating and vaporization, participating in combustion. This design not only effectively prevents safety hazards and environmental pollution caused by fuel spillage but also ensures that all fuel entering the system is converted into thermal energy, improving overall energy efficiency.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 - Appendix Figure 10This invention provides a novel integrated gasification chamber burner head, including a combustion support assembly, a gasification mixing assembly, and a combustion distribution assembly. To ensure the overall structural stability during operation, a support bracket 4 is provided at the bottom of the burner head. As the core foundation component at the bottom, the bottom of the combustion chamber 23 is fixedly connected to the support bracket 4. An airflow guide ring 3 is provided on the outer wall of the combustion chamber 23, located on its periphery and capable of independently guiding airflow. An oil receiving inner plate 6 is fixedly connected to the top of the combustion chamber 23. The oil receiving inner plate 6 serves as a mounting base, primarily used to fix the upper components of the central air inlet chamber 22. In order to achieve ignition and safety protection functions, the combustion chamber 23 is provided with a dedicated ignition needle mounting hole 12 and a flameout protection needle mounting hole 13. One end of the ignition needle mounting hole 12 and the flameout protection needle mounting hole 13 extends upward through and into the interior of the oil receiving inner plate 6, respectively, for installing and fixing the ignition needle sleeve and the flameout protection needle sleeve, so as to facilitate the ignition needle to perform ignition operation and the flameout protection needle to perform real-time monitoring of the flame status.

[0021] Regarding the core combustion and gasification structure, a burner base 15 is fixedly connected to the center of the inner oil receiving plate 6, and a burner 5 is fixedly connected to the top of the burner base 15. The unique mixing structure of this burner head is set on one side of the burner 5 and the burner head gasification chamber. The burner head gasification chamber is mainly composed of a gasification chamber upper cover 1, a gasification chamber middle cover 24, and a gasification chamber sealing layer 2 with a fixed plate. The gasification chamber upper cover 1 is located on the upper outer wall of the gasification chamber, and its inner wall is sealed to the gasification chamber middle cover 24 and the gasification chamber sealing layer 2 with a fixed plate to ensure airtightness. A mixed gas outlet 27 is provided between the gasification chamber middle cover 24 and the gasification chamber sealing layer 2 with a fixed plate. The bottom of the gasification chamber upper cover 1 is also fixedly connected to the gasification chamber sealing layer 2 with a fixed plate. The bottom of the gasification chamber sealing layer 2 with a fixed plate is further connected to the aforementioned air direction ring 3 and bracket 4, forming a stable sealed cavity structure.

[0022] To achieve efficient gasification premixing, this invention incorporates an integrated air and fuel device 14. This integrated air and fuel device 14 penetrates the gasification chamber cover 24 and extends upwards to the inner wall of the gasification chamber upper cover 1, with its top communicating with the interior of the gasification chamber upper cover 1. To prevent structural circumvention and optimize the feeding effect, the surface of the integrated air and fuel device 14 employs a special three-hole parallel layout design, specifically including three parallel feeding holes and air outlet holes 20, a fuel inlet 25, and an air inlet cover 26. These three parallel feeding holes are a central fuel inlet hole 17 and two air inlets 18 distributed on either side, or an air inlet hole 18 and two fuel inlets 17 distributed on either side. In terms of structural connectivity, the air inlets 18 are connected to the air outlet hole 20 and the air inlet cover 26, while the fuel inlets 17 are independently connected to the fuel inlet 25. The air inlets 18 and fuel inlets 17 are not interconnected and are vertically distributed on the surface of the integrated air and fuel device 14. This design ensures that although the fuel and air are physically isolated from each other, they maintain a consistent flow direction in the input area of ​​the inner wall of the gasification chamber cover 1. After the fluid enters the inner wall of the gasification chamber cover 1, it flows along a specific circulation path. During the heating process, the fuel is transformed from liquid to gas and achieves deep fusion with the air at the molecular level. It then enters the lower layer through the mixed gas outlet 27, greatly improving the chemical reaction rate.

[0023] The high-temperature gas, after gasification and premixing, needs to be transported to the combustion end. Therefore, a fuel outlet 21 is fixedly connected to the bottom of the gasification chamber cover 24, passing through the gasification chamber sealing layer 2 with a fixed plate. A U-shaped tube 16 is fixedly connected to the inner wall of the fuel outlet 21. The other end is connected to the ignition distributor connector, passing through the inner oil receiving plate 6 and communicating with the inside of the ignition distributor 5, thereby introducing the gasified fuel into the ignition distributor 5. An ignition distributor fixing cover 10 is fixedly covered and fixed to the outer wall of the ignition distributor 5, and the inner wall of the ignition distributor fixing cover 10 is fixedly connected to the outer wall of the ignition distributor 5. A fuel injection hole 19 is opened on the outer wall of the ignition distributor 5. Correspondingly, an L-shaped groove is opened on the inner wall of the ignition distributor fixing cover 10, and an outlet hole 11 is opened on the outer wall. The fuel injection hole 19, the L-shaped groove on the inner wall of the ignition distributor fixing cover 10, and the outlet hole 11 are connected in sequence. This structure utilizes the negative pressure siphon effect generated by the high-speed jet within the L-shaped groove to re-entrain the surrounding air for secondary mixing. The mixed gas is then violently ejected outward through the ejector hole 11.

[0024] To further maintain continuous and stable combustion, this invention designs a three-dimensional air intake and supply structure. A central air intake chamber 22 is located inside the combustion chamber 23. A first air inlet 8 is located on the bottom outer wall of the combustion chamber 23, and a first air outlet 7 is located on the top of the fuel receiving inner plate 6. The burner 5 is located at the top of the central air intake chamber 22. External air enters through the first air inlet 8, is guided upwards by the central air intake chamber 22, passes through the first air outlet 7, and finally, the mixed fuel is ejected from the ejector hole 11 inside the burner 5, mixing and burning again with the air from the second air outlet 9. It is worth noting that the second air outlet 9 inside the burner 5 is not connected to the fuel injection hole 19 that supplies the combustion gas, and the two are vertically distributed. This ensures that the centrally supplied air can directly supply the flame root, providing sufficient oxygen to the flame. Combined with the guiding effect of the airflow ring 3, this ensures efficient fuel utilization and stable combustion.

[0025] Working principle: During the operation of the equipment, the stability of the overall structure is supported by the bracket 4. The combustion chamber 23 serves as the core basic component at the bottom, used to fix the ignition needle sleeve, the flameout protection needle sleeve, and the central air inlet chamber 22. The oil receiving inner plate 6 is fixedly connected to the upper part of the central air inlet chamber 22. Its main function is to serve as a mounting base to fix the flame distributor base 15 and connect the U-shaped tube 16 connector. The air direction ring 3 located on the outer ring at the bottom of the combustion chamber 23 independently plays the role of guiding air and does not interfere with the oil receiving inner plate 6.

[0026] At the start of operation, fuel and air are input through an integrated air and fuel device 14 that runs through the upper cover 1 of the gasification chamber. To prevent structural circumvention and optimize the feeding effect, the integrated air and fuel device 14 adopts a three-hole parallel feeding layout design, with two air inlets 18 on the sides and a fuel inlet 17 in the middle. Although the fuel inlet 17 and the air inlet 18 are structurally isolated from each other, they maintain a consistent flow direction in the input area within the upper cover 1 of the gasification chamber to ensure the uniformity of subsequent mixing. After the fluid enters the interior of the upper cover 1 of the gasification chamber, it flows along a specific double-layer or multi-layer circulation path. The fuel and air first enter the uppermost space of the upper cover 1 of the gasification chamber, and under pressure, flow to the side opposite the inlet, entering the next layer of gasification chamber through the interlayer mixed gas outlet 27 opened there, and then circulating in the lower chamber. During this process, the material on the inner wall of the gasification chamber cover 1 is heated, causing the internal fuel to change from liquid to gas. Due to the increased intermolecular distance, the gaseous fuel can achieve deep fusion with air at the molecular level. This fully premixed state greatly enhances the chemical reaction rate, thereby making the subsequent flame combustion temperature significantly higher than that of ordinary liquid combustion.

[0027] The high-temperature gas, after vaporization and premixing, then enters the U-shaped tube 16, and is guided through the oil receiving inner plate 6 to enter the burner base 15, and then flows into the burner 5 at the top. At this time, the ignition needle installed in the ignition needle mounting hole 12 ignites the gas, and the flame protection needle installed in the flame protection needle mounting hole 13 monitors the flame. The high pressure of the vaporized fuel is injected at high speed from the fuel nozzle 19 on the side of the burner 5 into the burner fixing cover 10. Utilizing the negative pressure siphon effect generated around the burner 5 by the high-speed jet, the surrounding air is drawn in again for secondary mixing. The mixed gas is finally violently ejected outward through the ejection hole 11 on the outer wall of the burner fixing cover 10. At the same time, in order to maintain continuous combustion, the external air is supplied in three dimensions with the cooperation of the central air intake chamber 22 and the air direction ring 3. The air is guided by the structure of the central air intake chamber 22 and is directly injected upward with the second air outlet 9 at the top of the burner 5, providing sufficient oxygen for the flame and ensuring efficient fuel utilization and stable combustion.
