Movable Atomizer Core Structure to Prevent E-Liquid Corrosion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from e-liquid contacting the atomizer, leading to corrosion or oxidation of the heating element, reducing its lifespan and affecting vapor taste and user health.
Innovation Solution
An atomizer design that separates the e-liquid from the atomizing core when not in use, with the core moving between positions to control e-liquid flow and incorporating seals and positioning parts to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizing core remains stationary with e-liquid inlet inside the cartridge, then e-liquid flows smoothly during use, but the heating element corrodes or oxidizes due to continuous e-liquid contact
Solution Approach 1:
The atomizing core is designed to be movable rather than stationary, allowing it to dynamically change position between retraction (outside cartridge) and insertion (inside cartridge) states. This dynamic configuration enables the system to prevent corrosion during storage while ensuring proper e-liquid flow during use, resolving the contradiction between heating element lifespan and device simplicity.
Solution Approach 2:
The atomizing core is extracted from the cartridge during non-use periods, physically separating it from the e-liquid reservoir. This extraction prevents continuous contact between the heating element and e-liquid, thereby preventing corrosion and oxidation, while allowing the core to be reinserted when needed for vaporization.
2Reliability
If the atomizing core is moved between positions, then e-liquid contact with heating element is prevented, but the device requires additional positioning mechanisms
Solution Approach 1:
The atomizing core utilizes its own weight and the elastic recovery force of the sealing ring to automatically retract outside the cartridge when not in use, without requiring external actuation mechanisms. The sealing ring's elasticity provides the restoring force needed for automatic positioning, simplifying the overall device structure while maintaining reliable corrosion prevention.
Solution Approach 2:
The sealing ring acts as an intermediary element that provides both sealing function and positioning function. Its elastic properties enable it to push the atomizing core outward during storage while allowing inward movement during use, serving as a mechanical mediator that reduces the need for complex positioning mechanisms.
3Reliability
If the atomizing core retracts outside the cartridge, then corrosion is prevented, but e-liquid leakage may occur during movement
Solution Approach 1:
The sealing ring serves as a mediator between the atomizing core and the cartridge opening, providing a reliable seal during both retraction and insertion movements. Its elastic deformation capability allows it to maintain sealing contact throughout the movement cycle, preventing e-liquid leakage while enabling the corrosion-preventing retraction motion.
Solution Approach 2:
The sealing ring is implemented as a flexible elastic component that can deform to accommodate the movement of the atomizing core. This flexibility allows the seal to maintain contact and prevent leakage during dynamic operations, while the elastic recovery force aids in automatically retracting the core outside the cartridge during storage.
