Slide Valve Sealing Mechanism for Liquid Injecting Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refillable electronic cigarette users face unsatisfactory experiences due to tobacco liquid leakage during filling, as the injector is not fixedly coupled with the device, leading to leaks when the device is turned over.
Innovation Solution
A liquid injecting container with a housing, movable element, and elastic element, where the movable element moves axially to open or seal a liquid outlet when coupled or decoupled from the atomizer, preventing leakage by using a spring to drive the movable element back to a sealed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the injector is not fixedly coupled with the electronic cigarette, then the filling operation is simple and flexible, but the tobacco liquid leaks when the device is turned over
Solution Approach 1:
The patent employs a movable element that can dynamically change position between open and closed states. The movable element is driven by an elastic element (spring) to automatically close the liquid outlet when the injector is detached, while allowing it to open during filling operations. This dynamic mechanism resolves the contradiction by adapting the sealing state based on operational needs.
Solution Approach 2:
The elastic element (spring) provides self-service by automatically returning the movable element to the closed position when the injector is detached, without requiring additional user actions or complex control systems. The spring's elastic force naturally ensures the liquid outlet is sealed when not in use, maintaining reliability while preserving operational simplicity.
2Reliability
If a movable element with elastic element is added to seal the liquid outlet, then liquid leakage is prevented, but the device complexity increases
Solution Approach 1:
The patent uses a movable element that acts as a flexible closure mechanism for the liquid outlet. This movable element can be a simple plug or valve structure that flexes or moves to open/close the outlet, providing effective sealing without requiring complex rigid mechanical systems. The flexibility of the closure mechanism reduces overall device complexity while maintaining sealing reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents tobacco liquid leakage by ensuring the liquid outlet is sealed when not in use, enhancing user experience by maintaining a secure filling process.
Implementation Method 1
an elastic element in the open end, a first end of the elastic element abutting against a first end of the movable element
Implementation Method 2
the elastic element is capable of driving the movable element to move axially to a second position where the at least one liquid outlet is sealed

AI summary
The present disclosure relates to a liquid injecting container for an atomizer. The atomizer includes a liquid injecting opening. The liquid injecting container includes a housing, a movable element, and an elastic element. The housing defines a reservoir for storing tobacco liquid. The housing has an open end. The open end defines at least one liquid outlet. The movable element is capable of moving along an axial direction of the open end. The elastic element abuts against the movable element. When the open end is coupled to the liquid injecting opening, the movable element is capable of moving axially to a first position where the at least one liquid outlet is opened. When the open end is detached from the atomizer, the elastic element is capable of driving the movable element to move axially to a second position where the at least one liquid outlet is sealed.
