Microporous Atomizing Core to Reduce Heating Element Soot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accumulation of tobacco soot on the surface and periphery of the heating element in conventional atomizers affects user experience by causing burnt or peculiar smells and potentially harmful gases.
Innovation Solution
An atomizing core with a protective layer having micropores (30%-70% porosity and 100 μm-500 μm thickness) covering the heating element, which filters out liquid and solid particles to prevent soot formation, combined with a vent hole or through groove to facilitate smoke discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective layer is added to cover the heating element, then tobacco soot accumulation is reduced, but device complexity increases
Solution Approach 1:
The protective layer is designed with micropores having a porosity of 30%-70% to enable selective filtration. The porous structure allows smoke to pass through while trapping liquid and solid particles that would otherwise accumulate as soot on the heating element, thus reducing harmful factors without requiring a completely solid barrier
Solution Approach 2:
The protective layer acts as an intermediary component between the heating element and the incoming smoke. It intercepts and filters particles from the smoke before they reach the heating element surface, preventing direct contact and accumulation while still allowing the smoke to pass through for user inhalation
2Object-affected harmful factors
If the protective layer thickness is increased to improve filtration, then soot reduction effectiveness increases, but smoke flow resistance increases
Solution Approach 1:
The protective layer thickness is optimized to a specific range of 100 μm to 500 μm, and the porosity is controlled at 30%-70%. These parameter optimizations ensure sufficient filtration capability to reduce soot while maintaining adequate smoke flow. The micropore size and distribution are carefully controlled to balance particle capture efficiency with smoke permeability
3Object-affected harmful factors
If the protective layer covers the entire heating element, then soot accumulation is maximally reduced, but heating efficiency may be affected
Solution Approach 1:
The protective layer is designed with non-uniform micropore distribution, where the pore size and density vary in different regions. The micropores are strategically distributed to provide effective filtration while maintaining localized areas that facilitate efficient heat transfer to the liquid, thus preserving heating efficiency while reducing soot accumulation
