Gas Burner Curved Flow Path for Thorough Mixing Without Obstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas stoves suffer from pipeline obstruction due to bending in the gas pipeline, leading to blocked gas paths and inefficient mixing of gaseous fuel and air.
Innovation Solution
The gas burner design includes separate gas mixing and flow guide cavities with curved transitions between them, ensuring a longer path length for gas mixing and preventing accumulation at connections, while maintaining a compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the gas pipeline is extended to achieve more thorough mixing of gaseous fuel and air, then the mixing effect is improved, but the gas path may be blocked at bent positions, resulting in obstruction of the gas pipeline
Solution Approach 1:
The patent applies curved transition connections instead of sharp bends in the gas pipeline. The curved transitions between the gas mixing cavity, flow guide cavity, and gas supply cavity eliminate dead zones where gas could accumulate and block flow, while still providing sufficient path length for thorough mixing of fuel and air.
Solution Approach 2:
The gas mixing system is divided into separate cavities (gas mixing cavity, flow guide cavity, gas supply cavity) with distinct functions. This segmentation allows each cavity to be optimized for its specific purpose while maintaining overall system efficiency and preventing obstruction through proper flow guidance.
2Quantity of substance
If the path length of gas is increased to improve mixing, then the mixing effect is enhanced, but the burner body length becomes excessively long, making mounting and placement difficult
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement of the cavities, positioning them at different locations and orientations within the burner body. This dimensional optimization allows the gas to traverse a sufficiently long path for thorough mixing while keeping the overall burner body dimensions compact and suitable for mounting.
Solution Approach 2:
The flow guide cavity and gas supply cavity are arranged in a nested or closely integrated configuration, where the end of the flow guide cavity bends toward the gas supply cavity. This nesting reduces the overall length required while maintaining the necessary flow path for effective mixing.

Function Achieved in This Case
This design ensures thorough mixing of fuel and air, stabilizes the flame, and prevents pipeline obstruction, allowing for efficient and stable operation without excessive lengthening the burner body.
Implementation Method 1
Based on the curved transition connection between the first ejection cavity and the gas mixing cavity as well as the curved transition connection between the gas mixing cavity and the gas supply cavity, after the gas reaches a connection between the first ejection cavity and the gas mixing cavity as well as a connection between the gas mixing cavity and the gas supply cavity, the mixed gas may be guided through the transition connection to enter the first ejection cavity and the gas mixing cavity to prevent the mixed gas from being stuck and accumulated at the above-mentioned connections
Implementation Method 2
a path length of gas reaching the gas supply cavity is increased. As a result, the mixed gas is fully mixed during movement
