Stove Burner Segmented Fire-Spraying Ring to Reduce Manufacturing Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stove burners face issues with gas leakage due to manufacturing precision problems, leading to potential explosions and high production costs, primarily because the outer fire-spraying member requires high-precision manufacturing and expensive heat-resistant materials.
Innovation Solution
The design of a stove burner with a spiral mixing tube and independent structures for the outer fire-spraying ring and cover body allows for the use of lower-cost heat-resistant materials and ensures airtightness by directing gas escape through a bent channel, reducing the need for high manufacturing precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the manufacturing precision of the outer fire-spraying member is improved greatly to remove clearance, then the airtightness of the annular chamber is improved, but the production cost increases
Solution Approach 1:
A sealing ring is introduced as an intermediary component between the outer ring cover body and the inner ring tube. This sealing ring compensates for the clearance caused by manufacturing tolerances, ensuring airtightness without requiring high manufacturing precision. The sealing ring acts as a mediator that absorbs the dimensional variations while maintaining the seal integrity.
Solution Approach 2:
The invention changes the parameter of the sealing interface by introducing a flexible sealing ring that can deform to fill the clearance gap. Instead of relying on precise dimensional parameters of the rigid components, the system uses the elastic deformation parameter of the sealing ring to achieve the required tightness, thereby relaxing manufacturing precision requirements.
2Temperature
If the outer ring cover body is made of expensive heat-resisting material to contact flame, then the heat resistance is improved, but the manufacturing cost increases
Solution Approach 1:
The outer fire-spraying member is segmented into two independent parts: the outer fire-spraying ring that contacts the flame and requires heat-resisting material, and the outer ring cover body that can be made of cheaper material. This segmentation allows each component to be optimized independently - the fire-spraying ring gets the expensive heat-resistant material where needed, while the cover body uses lower-cost materials, thereby reducing overall manufacturing cost while maintaining necessary heat resistance.
Solution Approach 2:
Instead of making the entire outer ring cover body from expensive heat-resisting material, the invention applies heat-resisting material only to the outer fire-spraying ring portion that directly contacts the flame. The outer ring cover body can then be made of cheaper materials since it does not directly contact the flame. This local quality approach optimizes material usage and reduces cost while maintaining functionality.

AI summary
The present invention discloses a stove burner. The present invention, by designing the outer-ring fire cover body and the outer fire-spraying ring into two independent structures, enables the outer-ring fire cover body to be made of a heat-resisting material of low price, which reduces the manufacturing cost of the entire stove burner; besides, with the outer edge of the annular cover body plate in contact with the top of the outer fire-spraying ring and the cover body ring attached to the sidewall of the inner ring tube close to the gas inlet tube, this structure can better achieve good airtightness of the annular chamber.
