Atomizer Refill Structure With Movable Inlet Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional atomizers face issues with e-liquid leakage due to loose rubber plugs that fail to seal the inlet after refilling, leading to missing plugs and inefficient refilling processes.
Innovation Solution
An atomizer design featuring a movable e-liquid injection member with threaded engagement and a seal ring mechanism that ensures e-liquid chamber filling and sealing, preventing leakage by moving between positions to enter and exit the chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rubber plug is used to block the e-liquid inlet, then the inlet can be sealed, but the plug becomes loose and fails to seal properly after refilling, causing leakage
Solution Approach 1:
The injection member is designed to be movable between a first position (for refilling) and a second position (for sealing). This dynamic positioning allows the system to switch between open and sealed states, resolving the contradiction between ease of refilling and sealing reliability. The male thread and female thread enable controlled movement of the injection member to maintain reliable sealing while allowing periodic refilling operations.
2Reliability
If the e-liquid inlet is blocked by a rubber plug, then the chamber is sealed, but the plug is prone to being lost and fails to prevent leakage
Solution Approach 1:
The sealing function is merged with the injection member itself. The injection member incorporates both the refilling function and the sealing function in a single integrated component, eliminating the need for a separate rubber plug. This reduces device complexity while maintaining reliable leakage prevention through the threaded engagement mechanism.
3Productivity
If the injection member is movable between positions, then refilling efficiency is improved, but the mechanism requires threaded engagement which increases device complexity
Solution Approach 1:
The threaded engagement mechanism serves multiple functions: it provides structural support for the injection member, enables controlled movement between positions, ensures reliable sealing through precise positioning, and prevents over-tightening. This multi-functionality justifies the added complexity by eliminating the need for separate mechanisms for each function, ultimately simplifying the overall system.

AI summary
An atomizer includes a housing including an e-liquid chamber. The e-liquid chamber is equipped with an e-liquid injection member. The e-liquid injection member includes at least one first e-liquid inlet. The e-liquid injection member is movable between a first position and a second position; in the first position, the at least one first e-liquid inlet communicates with the e-liquid chamber; and in the second position, the at least one first e-liquid inlet is not in communication with the e-liquid chamber.
