Aerosol Flow Adjustment Chamber for Flavor Inhaler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-burning type flavor inhalers, the flow of aerosol in the second cartridge is polarized due to mismatched cross-sectional areas between the first and second flow paths, leading to incomplete passage of the flavor source without proper aerosol flow adjustment.
Innovation Solution
Incorporating an aerosol flow adjustment chamber between the first and second flow paths to suppress polarization, with a larger cross-sectional area in the second flow path and a cylindrical shape for the flavor source container, and using a mesh body with specific opening shapes to enhance the passage of aerosol and flavor components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second flow path has a larger cross-sectional area than the first flow path, then the aerosol flow is adjusted to prevent polarization, but the device structure becomes more complex
Solution Approach 1:
An aerosol flow adjustment chamber is introduced as an intermediary component between the first flow path and the second flow path. This chamber serves as a buffer zone that redistributes the aerosol flow, preventing polarization effects while maintaining a relatively simple overall device structure. The adjustment chamber acts as a mediator that decouples the structural simplicity from the flow uniformity requirement.
2Productivity
If a mesh body with specific opening shapes is used, then the passage of aerosol and flavor components is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
A mesh body with specifically designed opening shapes and distributions is employed in the flavor source container. The porous structure allows efficient passage of aerosol while maintaining flavor source integrity. The mesh design optimizes the balance between aerosol generation efficiency and manufacturing feasibility by using standard mesh fabrication techniques.
3Reliability
If the flavor source container has a cylindrical shape, then the aerosol flow distribution is improved, but the volume efficiency decreases
Solution Approach 1:
The flavor source container adopts a cylindrical shape with optimized dimensional proportions. The cylindrical geometry provides superior aerosol flow distribution and flavor release characteristics compared to other shapes. The design compensates for the increased volume by optimizing the height-to-diameter ratio and positioning the container strategically within the device architecture.

AI summary
This non-combusting flavor inhaler is provided with a first flow path which is disposed downstream of a vaporizer unit, and, as an aerosol flow path, a second flow path which is disposed downstream of the first flow path. The second flow path houses a flavor source for imparting flavor to an aerosol. In order to suppress unevenness of aerosol flow in the second flow path, an aerosol flow adjustment chamber for adjusting flow of the aerosol supplied from the first flow path is provided between the first flow path and the second flow path.
