Electronic Cigarette Refill Sealing With Spring-Activated Inlet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The refilling process of electronic cigarettes is cumbersome and prone to e-liquid spills due to the lack of effective sealing mechanisms.
Innovation Solution
An electronic cigarette design incorporating multiple seal rings and a spring-activated e-liquid sealer mechanism that ensures the atomizing core is sealed during refilling, preventing e-liquid leakage by opening and closing the e-liquid inlet based on the atomizing core's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the atomizing core is replaced frequently for refilling, then the e-liquid can be replenished, but the e-liquid leaks during the refilling process
Solution Approach 1:
The sealing structure transitions from a static seal to a dynamic seal that automatically adjusts based on the atomizing core position. The elastic sealing component deforms elastically to seal the e-liquid inlet when the atomizing core is inserted, and returns to its original state when removed, enabling automatic sealing without manual intervention.
Solution Approach 2:
An elastic sealing component acts as an intermediary between the holder body and the atomizing core. This intermediary element deforms to accommodate the atomizing core during insertion while maintaining the seal, and automatically returns to its sealing position when the atomizing core is removed, preventing e-liquid leakage during the refilling process.
2Ease of operation
If the e-liquid inlet remains open for refilling, then the refilling process is simple, but the e-liquid spills during atomizing core replacement
Solution Approach 1:
The elastic sealing component is pre-positioned to cover the e-liquid inlet before the atomizing core is inserted. When the atomizing core is removed for refilling, the seal automatically opens to allow refilling, and then automatically closes to prevent leakage, eliminating the need for manual sealing operations.
Solution Approach 2:
The sealing mechanism is designed to automatically open and close based on the presence or absence of the atomizing core. The elastic deformation of the sealing component provides self-actuating sealing functionality without requiring user intervention, making the system both easy to operate and leak-proof.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the refilling process by minimizing spills and ensuring a secure sealing mechanism, making it easier and more efficient to refill the e-liquid without leakage.
Implementation Method 1
the spring deforms, and the e-liquid inlet of the lower holder is opened, the e-liquid enters the atomizing core. When the atomizing core is pulled out, the spring resets
