Electronic Atomizer Integrated Injection-Molded Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomizer designs face manufacturing inefficiencies and quality control challenges due to the manual assembly of silica gel sealing members, which are soft and difficult to produce automatically, leading to low manufacturing efficiency and potential e-liquid leakage.
Innovation Solution
An electronic atomizer with a sealing member integrally formed on the closure member, featuring first, second, and third sealing portions that are injection-molded in one step, allowing for automatic assembly and reducing the need for separate silica gel components, while also incorporating a ceramic matrix and porous ceramic core for enhanced sealing and atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate silica gel sealing members are used, then sealing effect is achieved, but manual assembly is required and manufacturing efficiency is low
Solution Approach 1:
The patent integrates multiple separate sealing members into a single integrated sealing structure that is injection-molded directly onto the closure member. This merging of multiple sealing components (first sealing portion, second sealing portion, third sealing portion) into one piece eliminates manual assembly requirements while maintaining the sealing functionality, thereby resolving the contradiction between sealing reliability and manufacturing efficiency.
2Reliability
If separate sealing members are assembled, then sealing coverage is achieved, but assembly complexity increases and quality control becomes difficult
Solution Approach 1:
The patent combines multiple sealing portions into a single integrated sealing structure that is injection-molded as one piece onto the closure member. This integration reduces assembly complexity from multiple separate assembly steps to a single automated process while maintaining comprehensive sealing coverage through the multi-portional design of the integrated structure.
3Reliability
If silica gel materials are used for sealing members, then sealing flexibility is achieved, but automatic production becomes difficult
Solution Approach 1:
The patent changes the material parameter from soft silica gel to harder plastic material that can be injection-molded. This parameter change enables automatic production through injection molding while maintaining sealing flexibility through the integrated design that incorporates multiple sealing portions with appropriate geometries for different sealing requirements.

AI summary
An electronic atomizer includes a cartridge tube provided with an e-liquid storage cavity and a flue, a closure member closing the e-liquid storage cavity, a sealing member, an atomizing core provided in the closure member, and a base. The closure member includes a closure end, an accommodation end extending downward from closure end, a flow passage vertically penetrating through closure member, and an air passage separated from flow passage; the sealing member is integrally formed on closure member and includes a first sealing portion covering outer side of the atomizing core, a second sealing portion covering outer periphery of the closure end and abutting against inner wall surface of the cartridge tube, and a third sealing portion fitted to top end of the air passage and abutting against end edge of the flue; the e-liquid storage cavity communicates with upper end surface of atomizing core through the flow passage.
