Movable Sealing Insert for E-Cigarette Cartridge Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic cigarette cartridges are prone to liquid leakage during transportation and long periods of non-use due to fluid communication between the liquid storage chamber and the outside environment, leading to contamination.
Innovation Solution
A cigarette cartridge design featuring a movably positioned inserting portion that seals the liquid intake hole when not in use, preventing liquid contact and leakage, and extends to communicate with the storage chamber when in use, utilizing a housing with blocking protrusions and a smog passage for fluid communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid storage chamber is fluidly communicated with outside via the liquid guiding member, then the tobacco liquid can be supplied to the user during use, but liquid leakage and contamination occur during transportation or long-term non-use
Solution Approach 1:
The liquid guiding member is designed to be movable relative to the liquid intake hole, transitioning between a first position (sealed state during non-use) and a second position (open state during use). This dynamic positioning allows the system to adapt between leakage prevention mode and liquid supply mode, resolving the contradiction between reliability during storage and ease of operation during use
2Productivity
If the liquid guiding member is always positioned to allow fluid communication, then liquid can flow freely during use, but the liquid storage chamber is exposed to environmental contamination during non-use
Solution Approach 1:
The system is designed to automatically transition the liquid guiding member to the first sealed position before use begins, and to the second open position when use starts. This preliminary positioning action ensures the liquid storage chamber is protected from contamination before any liquid flow is needed, while maintaining efficient liquid flow when activated

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents liquid leakage during transportation and non-use periods by blocking the liquid intake hole when not in use, while ensuring proper fluid communication and atomization when the cartridge is activated.
Implementation Method 1
the inserting portion seals the liquid intake hole
Implementation Method 2
the heater is electrically driven to the heat up the tobacco liquid
Implementation Method 3
the liquid guiding member guides the tobacco liquid in the liquid storage chamber to the heater
Implementation Method 4
causing the tobacco liquid to be atomized to supply the user
