Atomizer Isolation Member for E-Liquid Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional atomizers face issues with e-liquid leakage and oxidation, which shorten the service life of the heating element and affect the taste of the e-liquid due to external air exposure and improper e-liquid flow.
Innovation Solution
An atomizer design incorporating an isolation member that can be moved to seal the e-liquid inlets, preventing leakage and oxidation, and a pull rod mechanism to control the e-liquid flow, ensuring the e-liquid is isolated from external air until use, thus extending the heating element's lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the e-liquid inlet is left open for e-liquid flow, then the atomizing function is enabled, but e-liquid leakage and oxidation occur
Solution Approach 1:
The isolation member is pre-positioned to seal the e-liquid inlet before the atomizer is activated. This preliminary sealing action prevents e-liquid leakage and oxidation during storage and transport, while allowing rapid transition to open state when the pull rod is pulled during actual use
Solution Approach 2:
The isolation member is designed to be movable rather than fixed, transitioning between sealed and open positions. When the pull rod is pulled, the isolation member moves to open the e-liquid inlet for atomizing operation; when released, it returns to seal the inlet, enabling dynamic adaptation between storage and usage states
2Reliability
If the isolation member is always sealed to prevent leakage, then e-liquid protection is improved, but e-liquid flow to heating element is blocked
Solution Approach 1:
The isolation member transitions from a static sealed state to a dynamic movable component. It seals the e-liquid inlet during storage, then moves when the pull rod is pulled during use to allow e-liquid flow to the heating element, resolving the contradiction between sealing and flow requirements
Solution Approach 2:
The pull rod acts as an intermediary mechanism that transfers user pulling force to the isolation member, controlling its movement between sealed and open positions. This intermediary control system enables reliable transition between the sealed storage state and the open atomizing state
3Stress or pressure
If external air enters the e-liquid tank to equalize pressure, then pressure balance is achieved, but e-liquid oxidization occurs
Solution Approach 1:
The isolation member provides preliminary sealing of the e-liquid inlet before the atomizer is activated, preventing external air from entering the e-liquid tank during storage and transport, thus avoiding e-liquid oxidization while maintaining pressure balance through the isolation mechanism
4Productivity
If the heating element is exposed to e-liquid before use, then atomizing is enabled, but service life is shortened
Solution Approach 1:
The isolation member is pre-positioned to seal the e-liquid inlet before the atomizer is activated, preventing e-liquid from contacting the heating element during storage. When the pull rod is pulled during use, the isolation member moves to allow e-liquid flow to the heating element, enabling atomizing while preserving heating element service life through delayed exposure

AI summary
An atomizer includes an e-liquid tank (1), an atomizing core, and an isolation member (2). The e-liquid tank includes an e-liquid chamber (105) and the atomizing core includes an at least one e-liquid inlet (301). The at least one e-liquid inlet communicates with the e-liquid chamber. The isolation member is disposed around and movable with respect to the atomizing core, and is configured to close the at least one e-liquid inlet. The isolation member comprises a pull rod (206) configured to drag the isolation member to slide away from the at least one e-liquid inlet.
