Atomizer Liquid Supply Assembly Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing electronic cigarette atomizers, tobacco liquid often leaks when replacing the atomizing core, causing inconvenience and affecting normal use due to incomplete usage of the liquid.
Innovation Solution
The atomizer design includes a liquid supply assembly with a movable element and elastic element that seals the through hole between the liquid chambers when the holder assembly is detached, preventing liquid leakage by moving the movable element to a position that closes the through hole, ensuring the first liquid chamber is cut off from the second, and featuring a detachable connection for easy refilling and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the atomizing core is made replaceable, then the atomizer can be maintained and reused, but tobacco liquid leaks when the atomizing core is removed
Solution Approach 1:
The sealing element is pre-installed on the holder assembly to seal the through hole before the atomizing core is removed. This preliminary sealing action prevents tobacco liquid from leaking when the atomizing core is taken out for replacement or maintenance.
Solution Approach 2:
A sealing element is introduced as an intermediary component between the holder assembly and the atomizing core. This sealing element selectively opens or closes the through hole based on whether the atomizing core is installed, thereby mediating the liquid flow path to prevent leakage during core replacement.
2Productivity
If the liquid chambers are connected via a through hole, then tobacco liquid can flow freely for aerosolization, but liquid leaks when the holder assembly is detached
Solution Approach 1:
The sealing element is designed to be movable, dynamically changing the state of the through hole from open to closed based on the installation status of the atomizing core. When the core is installed, the hole remains open for liquid flow; when detached, the hole closes to prevent leakage.
Solution Approach 2:
The sealing function is extracted as a separate, independent component (sealing element) that can operate autonomously based on the presence or absence of the atomizing core, rather than relying on the structural integrity of the assembled components alone.
3Ease of manufacture
If the atomizer uses a fixed structure, then manufacturing is simpler, but refilling and replacement are inconvenient
Solution Approach 1:
The atomizer is divided into separable modules: the holder assembly, the atomizing core, and the liquid supply assembly. This segmentation allows the atomizing core to be easily replaced and the liquid supply to be refilled independently, while the sealing element ensures these operations do not cause liquid leakage.
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
This design prevents liquid leakage during atomizer replacement, allows for efficient aerosolization, and enables the atomizer to be used as an independent refillable device, enhancing user convenience and reducing waste by ensuring all tobacco liquid is utilized.
Implementation Method 1
the elastic element exerts an elastic restoring force on the movable element, drives the movable element to move to the second position
Implementation Method 2
The atomizing core is configured for aerosolizing tobacco liquid to form aerosol

AI summary
An atomizer includes a mouthpiece assembly, a liquid supply assembly, a holder assembly, and an atomizing core. The liquid supply assembly includes a first liquid chamber, a second liquid chamber, an air pipe, a movable element, and an elastic element. A through hole is provided between the first liquid chamber and the second liquid chamber. The movable element is movable along the air pipe between a first position and a second position. When the holder assembly is engaged with the liquid supply assembly, the elastic element is compressed, the movable element is in the first position, and the first liquid chamber is in communication with the second liquid chamber via the through hole. When the holder assembly is detached from the liquid supply assembly, the elastic element drives the movable element to move to the second position, and the through hole is sealed.
