Description

Technical Field

[0001] This utility model relates to the field of gas combustion equipment technology, and in particular to a detachable gas diversion device for a gas burner head. Background Technology

[0002] As a core piece of equipment in modern kitchens, gas stoves' combustion performance and lifespan directly impact user experience. Currently, multi-ring gas burners on the market, such as those described in CN208504388U, generally employ an integral cast structure, solidifying the air intake, mixing, and exhaust chambers into a single, non-removable component. This traditional structure reveals several technical limitations in practical use: First, over long-term use, impurities in the gas and dust from the air easily accumulate carbon deposits within the gas passages, and the traditional integral structure cannot effectively clean the internal flow channels. When combustion efficiency decreases or malfunctions, the entire burner assembly often needs to be replaced, resulting in high maintenance costs and resource waste.

[0003] Secondly, the existing gas distribution structure has significant flaws. Most products employ a simple straight-through intake design, lacking optimization of airflow organization, resulting in uneven gas distribution between rings and affecting flame stability. Especially when adjusting the flame intensity of a single ring, pressure fluctuations often cause flame flickering in adjacent rings, making precise independent control difficult.

[0004] In addition, the existing flame structure design of the burner head also has shortcomings. Most products adopt the same or nearly equal height of the gas outlet layout, which causes the inner and outer ring flames to interfere with each other during combustion. The inner ring flame is easily "submerged" by the outer ring flame, resulting in poor flame stabilization performance under low load conditions and easy flameout.

[0005] While some improved designs attempt to enhance maintainability through modular connections, these solutions are largely limited to the detachability of external interfaces and fail to address the modular reconfiguration of the core gas flow path. The internal flow channels remain fixed, hindering truly convenient maintenance. Therefore, developing a flow distribution device that enables rapid assembly and disassembly of the core gas flow path, facilitates cleaning and maintenance, and simultaneously ensures uniform gas distribution and flame stability has become a pressing technical challenge in this field. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a gas diversion device that not only enables the rapid disassembly and installation of the core gas passage for easy cleaning and maintenance, but also improves combustion efficiency and stability through a unique structural design.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A gas diversion device for a gas burner head includes a main housing, a guide cylinder, a circular tube, and a connector. The main housing has a through hole at its bottom; the guide cylinder is fixedly disposed at the center of the main housing and extends upwards; the circular tube is detachably fitted inside the guide cylinder, with its lower end passing through the through hole at the bottom of the main housing; the connector is detachably connected to the bottom of the main housing and has an air inlet; the lower end of the circular tube passes through the main housing and forms a detachable connection with the connector; a central gas passage leading to the top of the main housing is formed between the guide cylinder and the circular tube.

[0008] Furthermore, the connector is a T-shaped structure, including mounting portions on both sides and a connecting cylinder in the middle; the mounting portions are fixed to the bottom surface of the main housing by bolts.

[0009] Furthermore, the connector has a snap-fit ​​interface at the top of the connecting cylinder and an annular protrusion at the lower end of the round tube, which engages with the snap-fit ​​interface.

[0010] Furthermore, the top of the main housing is provided with an outer ring vent and an inner ring vent, which are coaxially arranged with the guide cylinder.

[0011] Furthermore, the heights of the upper end face of the circular tube, the upper end face of the inner ring air outlet, and the upper end face of the outer ring air outlet decrease sequentially.

[0012] Furthermore, the main housing is also provided with a first air intake chamber and a second air intake chamber; the first air intake chamber is connected to the outer ring air outlet, and the second air intake chamber is connected to the inner ring air outlet.

[0013] Furthermore, the air intake interfaces of the first air intake chamber and the second air intake chamber are located on the front of the main housing; the first air intake chamber forms a first expansion portion extending downward to the right at the interface, and the second air intake chamber forms a second expansion portion extending downward at the interface, which is used to increase the cavity volume.

[0014] Furthermore, the volume of the first air intake chamber is greater than the volume of the second air intake chamber.

[0015] Furthermore, the bottom of the main housing is provided with at least one support rib extending upward to the bottom of the inner ring air outlet, for supporting the inner ring air outlet.

[0016] Furthermore, the bottom of the main housing is provided with at least two support feet.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. Modular cleaning and maintenance advantages: The detachable design of the round pipe and connectors allows for quick disassembly of the core gas passage. When cleaning is required, simply remove the fixing bolts of the bottom connector to remove the entire internal gas passage module, effectively solving the problem of difficult cleaning of integrated structures.

[0018] 2. Reliable sealing connection: The T-shaped structure of the connector provides stable fixed support through the mounting part, while the snap-fit ​​interface at the top of the connecting cylinder and the annular protrusion at the lower end of the round tube form a snap-fit ​​connection, which not only ensures the convenience of disassembly, but also helps to ensure the airtightness of the connection.

[0019] 3. Optimized flame structure: The top of the main casing can be equipped with coaxial outer and inner ring gas outlets, forming a multi-layer gas outlet structure with the central gas passage. Through the design of decreasing height of the upper end face of the circular tube, the upper end face of the inner ring gas outlet, and the upper end face of the outer ring gas outlet, the multi-layer flames are spatially staggered, which can effectively avoid mutual interference between flames, thereby improving combustion stability.

[0020] 4. High-efficiency intake system: The first expansion section of the first intake chamber and the second expansion section of the second intake chamber, through the expansion design at the interface, can effectively increase the chamber volume, reduce intake resistance, optimize the gas distribution effect, and improve the problem of low intake efficiency of traditional simple chamber structure.

[0021] 5. Enhanced structural stability: The supporting ribs at the bottom of the main housing extend upwards to support the inner ring air outlet, significantly enhancing the rigidity of the inner ring structure. This helps prevent deformation under long-term high-temperature use and extends the service life of the device. Attached Figure Description

[0023] It should be noted that the various dimensions, parameters, and numerical ranges given in the embodiments of this utility model are only to help those skilled in the art fully understand the technical solution of this utility model, and are not intended to limit the scope of protection of this utility model. Within the scope of the concept of this utility model, those skilled in the art can make adaptive adjustments to the following structures and parameters according to actual application scenarios and needs, and all such adjustments should fall within the scope of protection defined by the claims of this utility model.

[0024] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be noted that the following description is for illustrative purposes only and should not be construed as limiting the scope of protection of this utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides a gas diversion device, the core innovation of which is to solve the technical problems of traditional integrated gas burners, such as difficulty in cleaning and maintenance, uneven gas distribution and flame interference, through modular design.

[0026] To address the cleaning and maintenance challenges mentioned in the background section, this invention employs a unique detachable structure. The main housing 1 has a through hole 10 at its bottom, and a guide cylinder 11 is fixedly positioned at the center of the main housing and extends upwards. A circular tube 2 is detachably fitted inside the guide cylinder 11, with its lower end passing through the through hole 10. A connector 3 is detachably connected to the bottom of the main housing 1 via bolts. This design achieves modularity of the core gas passage. When internal carbon deposits need cleaning, simply remove the fixing bolts of the connector 3 to remove the circular tube 2 and connector 3 as a single module. This effectively solves the problem of traditional integrated structures being unable to clean the internal flow channels, significantly reducing maintenance costs.

[0027] To address the issues of uneven gas distribution and flame interference, this invention employs a multi-layered optimized design. The top of the main housing 1 may be equipped with a coaxially fitted outer ring gas outlet 41 and an inner ring gas outlet 42. A central gas passage is formed between the guide cylinder 11 and the circular tube 2 fitted inside it. The upper end of this passage, together with the inner and outer ring gas outlets, constitutes a multi-layered gas outlet structure. Specifically, the central gas outlet formed by the upper end face of the circular tube 2, the upper end face of the inner ring gas outlet 42, and the upper end face of the outer ring gas outlet 41 can be designed with progressively decreasing heights, maintaining a certain height difference (e.g., approximately 5 mm) between each layer. This three-dimensional layered structure allows the flames of each ring to be spatially staggered during combustion, helping to avoid the phenomenon of the inner and outer ring flames "submerging" each other, thereby improving flame stability, especially the flame stabilization performance under low-load conditions.

[0028] Regarding the optimization of the air intake system, a first air intake chamber 51 and a second air intake chamber 52 can be provided within the main housing 1, responsible for supplying gas to the outer and inner rings respectively. The first air intake chamber 51 can form a first expansion section 53 extending downwards to the right at the air intake interface, and the second air intake chamber 52 can form a second expansion section 54 extending downwards at the air intake interface. These expansion sections, by increasing the cavity volume, can effectively reduce intake resistance and stabilize airflow. Simultaneously, the volume of the first air intake chamber 51 can be larger than the volume of the second air intake chamber 52. This differentiated design allows the outer ring flame to receive more gas supply, facilitating more precise flame adjustment and improving the uneven gas distribution problem caused by traditional simple chamber structures.

[0029] To ensure reliable connection, connector 3 can adopt a T-shaped structure, including mounting portions 31 on both sides and a connecting cylinder 32 in the middle. The snap-fit ​​interface 33 at the top of the connecting cylinder 32 forms a reliable snap-fit ​​connection with the annular protrusion 21 at the lower end of the round tube 2. This design ensures both ease of disassembly and airtightness at the connection.

[0030] In terms of structural stability, the support ribs 421 at the bottom of the main housing 1 extend upwards to the bottom of the inner ring vent 42, providing effective support for the inner ring structure and preventing deformation under long-term high-temperature use. At the same time, the feet 12 symmetrically arranged at the bottom of the main housing 1 provide stable support for the entire device and promote heat dissipation by maintaining appropriate bottom space, ensuring long-term reliable operation of the device.

[0031] In a specific embodiment of this utility model, the following parameters may be used: the main housing 1 is integrally cast from high-temperature resistant cast iron or stainless steel; the guide cylinder 11 extends vertically upward from the center of the bottom of the housing, with a height 8-12mm higher than the bottom surface of the main housing 1; the outer diameter of the circular tube 2 maintains a fitting clearance of 0.1-0.3mm with the inner diameter of the guide cylinder 11; the annular protrusion 21 at the lower end of the circular tube 2 has a height of 0.5-1.0mm and a width of 2-3mm; the inner diameter of the outer ring vent 41 is 80-100mm, the inner diameter of the inner ring vent 42 is 50-60mm, and the outer diameter of the upper end of the guide cylinder 11 is 25-30mm. It should be emphasized that these parameters are merely examples and are not intended to limit the scope of this utility model.

[0032] The working principle of this invention is as follows: Gas can enter the device through multiple independent channels. The first channel of gas enters the outer ring outlet 41 through the first inlet chamber 51, forming the main heating flame; the second channel of gas enters the inner ring outlet 42 through the second inlet chamber 52, forming an auxiliary heating flame; the third channel of gas enters through the connector 3, and is ejected from the central outlet through the channel between the circular pipe 2 and the guide cylinder 11, forming the core heating flame. Each ring flame can be precisely adjusted through independent control valves, providing users with flexible firepower selection. The meticulous design of each component ensures reliable sealing performance and operational stability even after multiple disassemblies and reassemblies.

[0033] The above embodiments, through targeted structural design, effectively solve the various technical problems raised in the background art and achieve the beneficial effects described in this utility model. Within the scope of this utility model, those skilled in the art can adjust the specific dimensional parameters according to actual needs, and such adjustments should be considered to fall within the protection scope of this utility model. The protection scope of this utility model is determined by the claims.
