Microwave Heating Assembly Groove for Concentrated Aerosol Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices suffer from inefficient microwave energy utilization and dispersion, leading to low vapor generation and slow aerosol production due to inherent energy distribution in the microwave heating assembly.
Innovation Solution
A microwave heating assembly with an inner conductor unit featuring a groove on its surface to adjust energy field distribution, concentrating microwave energy on the aerosol generation substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a probe structure is used to insert the microwave heating assembly into the aerosol generation product, then the heating function is achieved, but the energy utilization efficiency is low and energy is excessively dispersed
Solution Approach 1:
The groove structure is introduced on the surface of the inner conductor unit to create non-uniform local quality in the microwave field. This causes the microwave energy to be concentrated in specific regions rather than uniformly distributed, improving energy utilization efficiency and aerosol generation speed while reducing energy loss
2Productivity
If microwave energy is distributed inherently without adjustment, then the heating assembly structure is simple, but the vapor generation amount is small and aerosol generation speed is slow
Solution Approach 1:
The groove structure on the inner conductor unit creates localized field enhancement regions, concentrating microwave energy where needed to increase vapor generation amount without significantly complicating the overall heating assembly structure
Solution Approach 2:
The groove introduces a new dimensional feature on the conductor surface, transforming the two-dimensional conductor surface into a three-dimensional structured surface that manipulates electromagnetic field distribution, thereby improving productivity with minimal structural complexity increase
3Ease of operation
If microwave energy is inherently distributed, then the heating assembly is compact, but energy is excessively dispersed resulting in localized scorching
Solution Approach 1:
The groove structure creates specific regions of enhanced and reduced field intensity, allowing controlled energy distribution that prevents localized scorching by directing energy away from sensitive areas while maintaining heating effectiveness in other regions
