E-Cigarette Refill Bottle Valve for Leak-Free Liquid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of adding tobacco liquid into existing electronic cigarettes is complicated and can dirty users' hands, and the process is slow, leading to potential leakage.
Innovation Solution
An electronic cigarette design featuring a detachable liquid bottle with an elastic one-way valve and a liquid guiding channel, allowing for easy and leak-proof refilling by utilizing the elastic properties of the valve to seal tobacco liquid within the storage cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the liquid inlet hole is opened for refilling, then the liquid storage cavity can be replenished, but the operation becomes complicated and slow
Solution Approach 1:
The device is divided into a reusable atomizing main body and a replaceable liquid bottle. The liquid bottle contains a sealed liquid outlet that automatically connects to the atomizing main body's liquid inlet hole, eliminating the need for manual opening and refilling operations. Users simply replace the entire liquid bottle rather than manually refilling.
Solution Approach 2:
The liquid bottle is equipped with an elastic valve that automatically opens when the bottle is inserted into the atomizing main body and automatically closes when removed. This self-activating mechanism eliminates the need for manual operation to open/close the liquid inlet hole, making the refilling process as simple as replacing the bottle.
2Quantity of substance
If the liquid inlet hole is opened for refilling, then the liquid storage cavity can be replenished, but tobacco liquid may leak and dirty the user's hands
Solution Approach 1:
The liquid outlet of the liquid bottle is pre-equipped with a sealed elastic valve that remains closed during normal handling and transport. The valve only opens when the bottle is properly inserted into the atomizing main body, preventing any possibility of leakage during storage, transport, or bottle replacement operations.
Solution Approach 2:
The liquid bottle is designed as a disposable component with an integrated sealed liquid outlet. Once the liquid is depleted or the seal is compromised, the entire bottle is discarded and replaced, eliminating the need for repeated opening/closing operations that could cause leakage and contamination.
3Quantity of substance
If waiting time is extended for liquid filling, then the liquid storage cavity can be properly filled, but service life is prolonged
Solution Approach 1:
The tobacco liquid is pre-filled and sealed within the liquid bottle during manufacturing. When the user needs to refill, they simply replace the pre-filled bottle with the atomizing main body, which automatically transfers the liquid. This eliminates the time-consuming process of manually pouring and waiting for liquid to fill the storage cavity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
