E-Cigarette Atomizer Cover for Easy Refill and Leak Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers for electronic cigarettes lack convenience in refilling tobacco liquid, as they often require complex mechanisms or sealing issues that complicate the injection process.
Innovation Solution
An atomizer design featuring a housing with a rotatable or slidable cover that exposes or covers injecting and vent holes, allowing easy access for refilling tobacco liquid, combined with a sealing mechanism using a seal ring to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a refillable atomizer is used to reduce usage cost, then the atomizer can be recycled and usage cost is reduced, but the injection process becomes complicated due to sealing issues and complex mechanisms
Solution Approach 1:
The atomizer is divided into a removable cover portion and a body portion. The cover can be detached to expose the injection hole, separating the refilling operation from the sealed storage state. This segmentation allows the atomizer to maintain sealing during normal use while enabling easy refilling when needed.
Solution Approach 2:
The cover is designed to be movable between a closed position (sealing the injection hole and vent hole) and an open position (exposing the holes for refilling). This dynamic structure allows the atomizer to transition between sealed storage mode and open refilling mode, resolving the contradiction between maintaining seals and enabling convenient injection.
2Ease of operation
If the injection hole is always exposed for easy refilling, then refilling convenience is improved, but liquid leakage occurs due to poor sealing
Solution Approach 1:
A seal ring is pre-installed around the injection hole and vent hole in the cover structure. This preliminary sealing arrangement ensures that when the cover is closed, the holes are automatically sealed without requiring additional sealing operations, preventing leakage while maintaining refilling convenience.
Solution Approach 2:
A flexible seal ring (made of elastomeric material) is used to create a reliable seal around the injection and vent holes. The flexible nature of the seal ring allows it to deform and conform to the hole openings, ensuring effective sealing when the cover is closed while allowing easy access when opened.
3Reliability
If a cover mechanism is added to control exposure of injection and vent holes, then sealing performance is improved, but device complexity increases
Solution Approach 1:
The sealing function and the cover function are merged into a single component. The cover itself incorporates the seal ring, eliminating the need for separate sealing mechanisms. This integration simplifies the overall structure while maintaining effective sealing when the cover is closed.
Solution Approach 2:
The cover serves multiple functions: it seals the injection hole and vent hole when closed, provides a surface for user interaction (rotation or sliding), and protects the internal components. This multi-functionality reduces the need for additional separate components, simplifying the overall device structure.
