Atomizer Air Venting Structure for E-Liquid Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional atomizers suffer from e-liquid leakage and inefficient filling due to air ingress, leading to staining and potential heater burnout from pressure differences.
Innovation Solution
An atomizer design with integrated air inlets and vents that directly communicate with the atomizing channel, ensuring smooth airflow and e-liquid flow, and includes features like absorbers to prevent leakage and facilitate faster filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air inlet is provided for smoke flow, then smoke can be driven to mouthpiece, but condensed e-liquid leaks along the atomization channel causing staining
Solution Approach 1:
The air inlet structure is segmented into multiple components: an air inlet channel for smoke flow, and a separate air vent channel for air circulation. This segmentation allows independent control of smoke delivery and air flow paths, preventing e-liquid from being carried along with the smoke stream while maintaining effective smoke delivery to the user.
2Device complexity
If e-liquid tank is isolated from outside environment, then filling is simpler, but air cannot flow in causing pressure difference and heater burnout
Solution Approach 1:
An air vent channel acts as an intermediary element that connects the isolated e-liquid tank to the external environment. This intermediary air passage allows air to flow into the tank to equalize pressure differences, preventing heater burnout, while maintaining the overall isolation and simplicity of the tank structure.
3Productivity
If air vent is added to e-liquid tank, then filling efficiency improves, but e-liquid may leak through the vent
Solution Approach 1:
The air vent channel is designed with specific local characteristics: it is positioned and dimensioned to allow air flow during filling while preventing e-liquid leakage. The channel's geometry and location provide selective permeability - allowing gas passage during normal operation while blocking liquid due to surface tension and flow dynamics.
