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 housing assembly, a liquid storage cavity, and an atomization cavity, equipped with a heating element and 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.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizer uses a conventional open structure for the atomization cavity, then the manufacturing process is simple and成本低, but the atomization medium leaks during transportation due to air pressure changes
Solution Approach 1:
The sealing bar is designed as a movable component that can dynamically switch between sealing and non-sealing states. During transportation, it moves to the first position to seal the air inlet and air outlet, preventing leakage. During use, it moves to the second position to allow normal atomization function, thus resolving the contradiction between leakage prevention and device complexity.
Solution Approach 2:
The sealing bar acts as an intermediary element between the atomization cavity and the external environment. It selectively controls the sealing of the air inlet and air outlet, enabling the system to adapt to different operational conditions (transportation vs. use) without requiring a completely sealed or completely open structure, thereby preventing leakage while maintaining functional simplicity.
2Reliability
If the sealing bar seals the air inlet and air outlet, then leakage is prevented during transportation, but the structure becomes more complex
Solution Approach 1:
The sealing bar employs a movable design that transitions between sealed and open states based on operational needs. This dynamic mechanism allows the atomizer to achieve reliable sealing during transportation without requiring a permanently complex sealed structure, maintaining ease of manufacture while improving sealing performance.
Solution Approach 2:
The system changes the sealing parameter (open/closed state) of the air inlet and air outlet based on operational conditions. During transportation, the sealing bar closes the openings to prevent leakage; during use, it opens them for normal function. This parameter change allows the system to achieve high sealing performance when needed without permanently increasing manufacturing complexity.
3Ease of operation
If the atomizer maintains an open structure for normal operation, then ease of use is maintained, but air pressure changes cause leakage during carrying
Solution Approach 1:
The sealing bar is designed to be movable, allowing the atomizer to dynamically switch between open (for ease of operation during use) and sealed (for leakage resistance during transportation) states. This resolves the contradiction by enabling the structure to adapt to different operational contexts without permanently compromising either ease of use or leakage resistance.
Solution Approach 2:
The sealing bar provides preliminary protective action by sealing the air inlet and air outlet before transportation begins. This preemptive sealing prevents air pressure changes during carrying from causing leakage, while the ability to open the sealing during use maintains ease of operation, thus resolving the contradiction between leakage resistance and ease of use.
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 sealing bar effectively reduces the risk of leakage by isolating the atomization cavity from external air pressure changes, while also simplifying the manufacturing process and lowering costs.
Implementation Method 1
the sealing bar is in elastic sealing fit with the housing assembly at the air outlet and the air inlet, separately

AI summary
An atomizer includes: a housing assembly, a liquid storage cavity and an atomization cavity being formed in the housing assembly, the atomization cavity having an air inlet and an air outlet that are provided coaxially; a heating element arranged in the housing assembly and in communication with the atomization cavity and the liquid storage cavity, separately; and a sealing bar including an integrated connection structure. 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.
