Detachable Atomization Assembly for Reusable E-Liquid Cartridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic atomization devices integrate e-liquid and atomization assembly, leading to waste of the atomization assembly when the e-liquid is depleted, increasing smoking costs due to the integrated design.
Innovation Solution
A detachable liquid storage member is introduced, allowing the atomization assembly to be reused by replacing the liquid storage member when empty, with a design that ensures smooth removal and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid storage member and atomization assembly are integrated into one piece, then the device structure is simple and easy to manufacture, but the atomization assembly is wasted when the e-liquid is finished, increasing smoking costs
Solution Approach 1:
The device is divided into separate components: the liquid storage member (cartridge) and the atomization assembly are detached from each other. The liquid storage member can be removed and replaced independently when the e-liquid is depleted, allowing the atomization assembly to continue being used. This segmentation resolves the contradiction by enabling selective replacement of only the consumable liquid storage member while retaining the reusable atomization assembly.
2Device complexity
If the liquid storage member and atomization assembly are integrated into one piece, then the device structure is simple, but the utilization rate of the atomization assembly is low
Solution Approach 1:
By segmenting the device into a replaceable liquid storage member and a reusable atomization assembly, the utilization rate of the atomization assembly is improved. The atomization assembly can be reused multiple times with different liquid storage members, increasing its productivity and utilization rate while maintaining relatively simple device structure through modular design.
Solution Approach 2:
The atomization assembly is designed with universal functionality that can work with multiple liquid storage members. The atomization assembly serves multiple functions: it atomizes e-liquid, provides structural support, and interfaces with the liquid storage member through standardized connection structures (liquid inlet passage, sealing structures), enabling repeated use and high utilization rate.
3Productivity
If the liquid storage member is detachable, then the utilization rate of the atomization assembly is improved, but the device structure becomes more complex
Solution Approach 1:
The detachable design segments the device into modular components with standardized interfaces. The liquid storage member includes a liquid storage chamber and cover with fluid passage, while the atomization assembly includes an atomization chamber and heating element. The connection structures (liquid inlet passage, sealing members) are designed to facilitate easy attachment and detachment, improving utilization rate while controlling complexity through standardization.
Solution Approach 2:
The liquid storage member is designed to be inserted into and nested within the atomization assembly. The liquid storage member mounting seat receives the liquid storage member, and the cover with fluid passage nests within the liquid storage chamber. This nesting arrangement enables compact integration when assembled while allowing easy separation for replacement, balancing structural complexity with usability.
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
Improves the utilization rate of the atomization assembly by enabling replacement of the liquid storage member, reducing waste and lowering smoking costs.
Implementation Method 1
The elastic cover has the fluid passage, or the fluid passage is defined by the elastic cover and the shell cover
Implementation Method 2
The piston is configured to move relative to a cup wall of the liquid cup in the first direction or in a direction opposite to the first direction
Implementation Method 3
The e-liquid is located above the atomization assembly, and under the effect of gravity, the e-liquid will automatically flow to the atomization assembly

AI summary
The present disclosure discloses an electronic atomization device including a housing and an atomization assembly. The housing has an air outlet, an atomization mounting seat, and a liquid storage member mounting seat. A direction from the atomization mounting seat towards the air outlet is a first direction, and a direction from the atomization mounting seat towards the liquid storage member mounting seat is a second direction. The first direction is substantially perpendicular to the second direction. The atomization assembly is disposed at the atomization mounting seat. The atomization mounting seat has an outer surface protruding in the first direction to form a liquid inlet passage.
