Atomizer Pressure-Relief Structure for Leak-Stable E-Liquid Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-cigarettes suffer from unstable internal air pressure and e-liquid leakage due to the lack of a pressure relief structure, particularly during simulated high-altitude testing, leading to increased costs and reduced competitiveness.
Innovation Solution
An atomization device with an air guide pressure relief member, including an air guide tube and circulating e-liquid compartment, balances pressure by allowing e-liquid to flow through circulating e-liquid holes, stabilizing internal air pressure and preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no pressure relief structure is provided in the e-liquid cup barrel, then the device structure remains simple, but the internal air pressure becomes unstable and e-liquid leakage occurs under high altitude conditions
Solution Approach 1:
The e-liquid cup barrel is divided into multiple functional zones: an upper e-liquid storage area, a lower circulating e-liquid compartment, and intermediate pressure relief channels. This segmentation allows different regions to perform specialized functions (storage, pressure regulation, e-liquid circulation) independently, resolving the contradiction by adding functional complexity only where needed rather than throughout the entire structure.
Solution Approach 2:
A breathable membrane is introduced as an intermediary component between the e-liquid storage area and the circulating e-liquid compartment. This membrane selectively allows air molecules to pass through while blocking e-liquid, serving as a mediator that enables pressure equalization without causing leakage. The membrane resolves the contradiction by providing a controlled interface that balances pressure stability requirements with structural simplicity.
2Reliability
If the e-liquid cup barrel is sealed completely, then e-liquid leakage is prevented, but pressure buildup occurs under high altitude conditions
Solution Approach 1:
Different regions of the e-liquid cup barrel are given different sealing properties: the main body maintains high sealing quality to prevent leakage, while specific localized areas (the circulating e-liquid compartment and pressure relief channels) have controlled permeability to manage pressure. This local differentiation resolves the contradiction by applying sealing selectively rather than uniformly throughout the entire structure.
Solution Approach 2:
The design utilizes pneumatic principles by introducing air circulation channels and a breathable membrane that allow controlled air flow through the e-liquid compartment. This pneumatic system enables pressure equalization between the interior and exterior environments, resolving the contradiction between maintaining seals for leakage prevention and allowing pressure relief through controlled air permeability.
3Reliability
If pressure relief channels are added to the e-liquid cup barrel, then pressure stability improves, but the device complexity increases
Solution Approach 1:
The pressure relief function is merged with the existing e-liquid cup barrel structure rather than being implemented as a separate external component. The circulating e-liquid compartment and pressure relief channels are integrated into the barrel's wall structure, combining multiple functions (e-liquid storage, air circulation, pressure relief) into a single unified component. This merging resolves the contradiction by achieving pressure relief stability without proportionally increasing overall device complexity.
Solution Approach 2:
The e-liquid cup barrel is designed with multi-functionality: it simultaneously serves as an e-liquid storage container, an air circulation chamber, and a pressure relief mechanism. The breathable membrane and circulating compartment perform multiple roles (separation, filtration, pressure regulation) within a single integrated structure. This multi-functionality resolves the contradiction by consolidating multiple components into one universal element.
