Electronic Cigarette Movable Cover Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from e-liquid leakage due to the lack of proper sealing of the e-liquid filling hole on the atomizer, which is directly disposed on the wall surface and not adequately sealed during the replacement process.
Innovation Solution
The electronic cigarette design incorporates a mouthpiece assembly, atomization assembly, and base assembly with a movable cover and slidable block system, featuring a seal gasket, seal rings, and an elastic sealing device to ensure the e-liquid filling hole is properly sealed, preventing leakage by using a connection bolt, seal sleeve, and spring mechanism to expose and block the filling hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the e-liquid filling hole is directly disposed on the wall surface of the atomizer, then the structure is simple and easy to manufacture, but the sealing is inadequate causing e-liquid leakage during atomizer replacement
Solution Approach 1:
The filling hole structure is segmented into multiple components: a filling hole formed in the atomizer body, a sealing ring embedded in the filling hole, and a movable cover that can slide to expose or cover the filling hole. This segmentation allows each component to perform its specific function - the atomizer provides structural support, the sealing ring ensures liquid-tight sealing, and the movable cover controls access to the filling hole, thereby resolving the contradiction between manufacturing simplicity and sealing reliability.
Solution Approach 2:
A movable cover is introduced as an intermediary component between the filling hole and the external environment. This cover slides along the axis of the filling hole to either expose it for filling or cover it to prevent leakage. The intermediary cover mechanism enables reliable sealing during atomizer replacement while maintaining ease of manufacture through a straightforward sliding structure that can be integrated into the existing atomizer design.
2Device complexity
If the e-liquid filling hole is directly disposed on the wall surface of the atomizer, then the structure is simple, but e-liquid leakage occurs when replacing the atomizer
Solution Approach 1:
The sealing ring is preliminarily installed and embedded in the filling hole of the atomizer before the atomizer is assembled or used. This preliminary sealing action ensures that the filling hole is already sealed and ready to prevent leakage, while the movable cover is positioned to cover the filling hole by default. These preliminary actions prevent e-liquid leakage during atomizer replacement without significantly increasing device complexity, as the sealing structure is integrated into the atomizer manufacturing process.
Solution Approach 2:
The movable cover is designed to slide dynamically along the axis of the filling hole, transitioning between a covered state (preventing leakage) and an exposed state (allowing filling). This dynamic mechanism resolves the contradiction by providing automatic leakage prevention during normal operation and atomizer replacement, while maintaining relatively simple device complexity through a straightforward sliding structure that can be actuated by user input or automatic mechanisms.
3Reliability
If a movable cover and slidable block system is added to cover and expose the e-liquid filling hole, then e-liquid leakage is prevented, but the device complexity increases
Solution Approach 1:
The movable cover and slidable block are merged into an integrated assembly where the slidable block is received by the atomizer body and the movable cover is connected to the slidable block. This merging combines multiple functions - sealing, sliding motion, and structural support - into a unified component system. The integrated design prevents e-liquid leakage through reliable sealing while minimizing device complexity by reducing the number of separate parts and simplifying the assembly process, as the merged structure can be manufactured and assembled as a single unit or pre-assembled module.
