Atomizer Air Passage Segmentation for E-Cigarette Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing atomizer designs in electronic cigarettes suffer from tobacco liquid condensation and leakage due to straight-through air passages, which lead to pollution and reduced aerosolization efficiency.
Innovation Solution
An upgraded air passage structure with a blocking piece that divides the air passage into independent inlet and outlet areas, positioned differently from the atomizing chamber, and staggered inlets and outlets to prevent condensation leakage, allowing for multiple reheating and aerosolization cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a straight-through air passage is used to achieve fast air flow, then air passage speed is improved, but condensing tobacco liquid leaks out from the air inlet or outlet causing pollution
Solution Approach 1:
The air passage is segmented into distinct air inlet area and air outlet area by the blocking piece, with each area positioned at different axial positions relative to the atomizing chamber. This segmentation prevents direct straight-through flow and allows condensing liquid to be retained in the atomizing chamber while maintaining efficient air flow paths.
Solution Approach 2:
The blocking piece serves as an intermediary element that divides the air passage and prevents direct connection between the air inlet and outlet areas. It mediates the airflow by forcing it to pass through the atomizing chamber in a controlled manner, preventing liquid leakage while maintaining aerosolization efficiency.
2Productivity
If air inlet is disposed below the atomizing chamber for straight-through flow, then air passage efficiency is improved, but condensing tobacco liquid leaks out causing pollution
Solution Approach 1:
The air passage is divided into separate air inlet area and air outlet area by the blocking piece, with each area positioned at different axial positions. This segmentation maintains efficient aerosolization by ensuring air flows through the atomizing chamber while preventing liquid leakage through the blocked pathway.
Solution Approach 2:
Instead of positioning the air inlet below the atomizing chamber for direct straight-through flow, the invention inverts the approach by positioning the air inlet area and air outlet area at different axial positions with the blocking piece preventing direct flow. This inversion maintains productivity while eliminating the harmful liquid leakage effect.
