Atomizer Sealing Bar Structure for Pressure-Induced Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-forming devices are prone to leakage of the atomization medium during transportation or carrying due to air pressure changes.
Innovation Solution
An atomizer with a sealing bar that can be positioned to seal the air inlet and air outlet of the atomization cavity, reducing the impact of external air pressure changes on the liquid storage cavity and thereby minimizing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizer is equipped with a sealing bar to prevent leakage during transportation, then leakage resistance is improved, but device complexity increases
Solution Approach 1:
The sealing bar is designed as a movable component that can dynamically change position between a first position (sealing the air inlet and air outlet) and a second position (detached from the atomizer). This dynamic design allows the same structure to provide leakage protection during transportation while maintaining normal atomization function during use, resolving the contradiction between reliability and device complexity
Solution Approach 2:
The sealing function is segmented from the main atomizer body as a separate, removable sealing bar component. This segmentation allows the sealing mechanism to be independently designed and positioned, enabling it to seal both the air inlet and air outlet simultaneously without interfering with the overall atomizer structure, thus improving leakage resistance while controlling complexity
2Reliability
If the sealing bar seals both air inlet and air outlet, then leakage prevention is improved, but manufacturing complexity increases
Solution Approach 1:
The sealing bar integrates multiple sealing functions into a single component that simultaneously seals both the air inlet and air outlet. By merging these sealing functions into one integrated structure rather than using separate sealing mechanisms for each opening, the design improves leakage prevention while actually simplifying manufacturing compared to multiple separate sealing components
Solution Approach 2:
The sealing bar serves multiple functions: it seals the air inlet, seals the air outlet, and can be positioned in different states (first position for sealing, second position for detachment). This multi-functionality allows a single component to provide comprehensive leakage protection without requiring multiple specialized parts, thereby improving reliability while maintaining ease of manufacture

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 sealing bar effectively reduces leakage of the atomization medium by isolating the atomization cavity from external pressure changes, while also simplifying the manufacturing process and lowering costs.
Implementation Method 1

AI summary
This application discloses an atomizer and an aerosol-forming device including the atomizer. The atomizer includes a housing assembly, a heating element and a sealing bar. A liquid storage cavity and an atomization cavity are formed in the housing assembly. The heating element is arranged in the housing assembly and is in communication with the atomization cavity and the liquid storage cavity separately. The atomization cavity has an air inlet and an air outlet that are provided coaxially. When the sealing bar is at a first position, the sealing bar passes through the atomization cavity in an axial direction of the atomizer, and the sealing bar is in elastic sealing fit with the housing assembly at the air outlet and the air inlet separately. When the sealing bar is at a second position, the sealing bar is completely detached from the atomizer. The sealing bar is an integrated connection structure.
