Rotating Sealing Mechanism for Leak-Free E-Cigarette Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refillable electronic cigarette users face leakage issues when filling tobacco liquid due to the lack of a secure connection between the injector and the device, leading to an unsatisfactory user experience.
Innovation Solution
A liquid injecting container with a hollow housing, a sealing component, and a rotating body that can be driven by the refillable device to rotate between sealing and opening positions, ensuring secure filling without leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the injector is not fixedly coupled with the electronic cigarette, then the device structure is simple and easy to assemble, but the tobacco liquid leaks when the electronic cigarette is turned over
Solution Approach 1:
The sealing component transitions from a static sealing state to a dynamic opening state through rotation. The rotating body allows the sealing component to move between blocking the liquid outlet (sealed) and exposing the liquid outlet (open), enabling controlled liquid flow while maintaining connection stability during refilling operations
Solution Approach 2:
The connection structure is divided into separate functional components: a connection component for mechanical attachment, a sealing component for liquid containment, and a rotating body for state transition. This segmentation allows each component to perform its specific function independently while working together to prevent leakage during refilling
2Reliability
If the sealing component is always closed, then the liquid leakage is prevented, but the liquid cannot flow into the refillable device
Solution Approach 1:
The sealing component is made dynamic through the rotating body mechanism. By rotating the rotating body, the sealing component transitions between blocked and open states, allowing users to control liquid flow on demand. This dynamic adjustment enables both leakage prevention during storage and efficient refilling when needed
Solution Approach 2:
The rotating body serves as an intermediary mechanism between the user's manual operation and the sealing state. Rotating the rotating body indirectly controls the sealing component's position, providing a simple user interface to switch between sealed and open states without directly manipulating the sealing component itself

AI summary
The present disclosure relates to a refillable device. The refillable device includes a liquid chamber in the refillable device, a connection end, a sealing component arranged in the connection end, and a rotating mechanism. The liquid chamber is configured for storing tobacco liquid. The connection end is configured for connecting with an open end of a liquid injecting container. The sealing component defines a liquid inlet. The rotating mechanism tightly abuts against the sealing component. The rotating mechanism is rotatable between a first position where the liquid inlet is opened, and a second position where the liquid inlet is sealed.
