Portable Atomizer Cartridge Airflow Structure for Leak-Safe Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic cigarettes face issues with insufficient air intake due to manufacturing precision errors in the gap size between the cartridge and receiving chamber, leading to E-liquid leakage, contamination, and reverse power supply problems caused by incorrect plugging, as well as insecure connections and inconvenient operation due to poor design and assembly.
Innovation Solution
The introduction of an independent air intake structure with a novel air flow channel design and snap-fitting mechanism that allows external air to enter the atomizing core independently, preventing reverse power supply through foolproof connections, and enhancing the atomization process with a press-connection method for secure terminal connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gap between the cartridge exterior wall and receiving chamber is kept small for reliable mounting, then the cartridge mounting reliability is improved, but the air intake amount becomes insufficient
Solution Approach 1:
The air intake function is segmented from the gap between cartridge and receiving chamber, and independently implemented through air inlet holes in the cartridge body. This allows the gap to be minimized for mounting reliability while air intake is ensured through dedicated channels.
Solution Approach 2:
Air inlet holes serve as intermediary structures that provide a dedicated air intake path, decoupling the air intake function from the mechanical fit between components. This mediator ensures sufficient air supply without compromising mounting reliability.
2Quantity of substance
If the gap between cartridge and receiving chamber is enlarged for air intake, then the air intake amount is improved, but the cartridge becomes loose and prone to leakage
Solution Approach 1:
The air intake function is separated from the mounting interface by introducing dedicated air inlet holes. This segmentation allows the mounting gap to remain small for reliability while air intake is guaranteed through independent channels.
3Device complexity
If conventional plugging connection is used, then the device structure is simple, but reverse power supply cannot be avoided due to incorrect plugging
Solution Approach 1:
The connection structure employs asymmetric design where the cartridge can only be inserted in the correct orientation. This asymmetry prevents reverse power supply by making incorrect plugging physically impossible, while adding minimal complexity to the connection mechanism.
4Strength
If welding is used to connect heating member and terminal, then the connection strength is improved, but the heating member may separate during assembly process
Solution Approach 1:
The heating member is pre-fixed to the atomizing core before assembly with the cartridge. This preliminary action ensures the heating member remains securely positioned throughout the assembly process, preventing separation while maintaining strong final connection.

AI summary
An atomization generating device includes a main body and a cartridge having an exterior housing and a bottom base. The exterior housing includes an opening at a lower portion, an air outlet at a top portion, and an open hole at a side wall. The bottom base is mounted at the opening of the lower portion of the exterior housing. An upper portion of the bottom base is provided with an atomizing core connected with the air outlet through a vapor channel. An upper portion of the main body includes a receiving chamber for receiving the cartridge. The receiving chamber includes an air inlet corresponding to the open hole. The bottom base includes an air guiding channel for guiding an external air into the atomizing core. An end of the air guiding channel is connected with the atomizing core, another end is connected with the air inlet and the open hole.
