Integrated Porous-Body Atomizer for Leak-Resistant Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers for smoking alternatives, such as e-cigarettes, require complex rigid support elements and seal elements during assembly, complicating the assembly process.
Innovation Solution
An atomizer design featuring a housing, a first sealing member with a liquid storage cavity and airflow opening, a base for support, and an atomization element with a porous body and integrated heating element, where the porous body spans the airflow opening to prevent liquid ingress and is supported by a support frame, reducing component count and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a block-shaped porous ceramic body with groove and rigid support elements is used, then liquid substrate transfer is achieved, but assembly complexity increases due to many components
Solution Approach 1:
The patent combines the porous body, support frame, and sealing functions into an integrated assembly. The porous body is directly mounted on the support frame which provides both mechanical support and sealing, eliminating the need for separate rigid support elements and seal elements, thus reducing component count while maintaining functional reliability
Solution Approach 2:
The support frame serves multiple functions simultaneously: it provides mechanical support for the porous body, creates sealing against the housing wall, and defines the liquid storage cavity. This multi-functionality reduces the number of components needed compared to traditional designs requiring separate support elements and seal elements
2Stability of the object's composition
If multiple rigid support elements and seal elements are used, then structural stability is ensured, but assembly process becomes complicated
Solution Approach 1:
The support frame integrates multiple functions including mechanical support, sealing, and structural stabilization. By combining these functions into a single component rather than using multiple separate elements, the assembly process is simplified while structural stability is maintained through the frame's design
3Reliability
If the porous body completely covers the first opening, then liquid ingress is prevented, but airflow passage is blocked
Solution Approach 1:
The porous body is selectively positioned to cover only the necessary portions of the first opening for liquid ingress prevention, while leaving gaps or openings in specific locations to allow airflow passage. This localized coverage approach ensures liquid prevention where needed while maintaining airflow pathways for aerosol generation
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 simplified design results in a more straightforward assembly process and fewer components, ensuring efficient aerosol generation and airflow without liquid leakage, enhancing user experience.
Implementation Method 1
a heating element integrated on the porous body. The porous body spans the first opening, and at least part of the porous body abuts against a surface of a side of the first sealing member facing the liquid storage cavity
Implementation Method 2
The liquid is heated to be atomized, so as to generate an inhalable steam or aerosol

AI summary
An atomizer and an electronic atomization device are provided, The atomizer includes: a housing; a first sealing member, arranged inside the housing, and defining, with an inner wall of the housing, a liquid storage cavity used for storing a liquid substrate, a first opening used for guiding an airflow to pass through being defined on the first sealing member; a base configured to support the first sealing member; and an atomization element held on the first sealing member and configured to atomize the liquid substrate. The atomization element includes a porous body and a heating element integrated on the porous body. The porous body spans the first opening, and at least part of the porous body abuts against a surface of a side of the first sealing member facing the liquid storage cavity, to prevent the liquid substrate from entering the first opening through the liquid storage cavity.
