Electronic Cigarette Atomizing Core with Elastic Interference Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic cigarette atomization devices are costly and environmentally polluting due to the need for entire device replacement when the internal tobacco-juice is exhausted, and the replaceable atomizing core components are inconvenient to install and disassemble because they are typically assembled with screw threads.
Innovation Solution
An atomization device with an atomizing base featuring an installation space and insertion port, where the atomizing core component is removably installed, allowing for easy installation and disassembly without the need for rotation or other driving controls, using elastic interference fits and seals to secure the component in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the atomizing core component is fixed with screw threads, then the connection strength is improved, but the ease of installation and disassembly deteriorates
Solution Approach 1:
The atomizing core component is divided into two parts: a first part that is interference-fit into the air duct and a second part that is interference-fit into the insertion port. This segmentation allows the component to be securely fixed without requiring screw threads, enabling tool-free installation and disassembly while maintaining connection strength.
Solution Approach 2:
The traditional screw thread mechanical fastening system is replaced with an elastic interference fit mechanism. The elastic deformation of the sealing rings creates frictional force that secures the atomizing core component in place, eliminating the need for rotational fastening operations and enabling simple push-in and pull-out operations.
2Reliability
If the entire atomizing device is replaced when tobacco-juice is exhausted, then the reliability is improved, but the loss of substance and cost increase
Solution Approach 1:
The atomizing core component, which is the part that becomes clogged and fails over time, is extracted as a separate removable element from the atomizing device body. This allows users to replace only the failing core component rather than the entire device, reducing material waste and cost while maintaining device reliability through component replacement.
Solution Approach 2:
The design enables selective discarding of the consumable atomizing core component while recovering and reusing the durable atomizing device body (including the air duct and insertion port structure). This extends the overall device lifecycle and reduces waste by separating the disposable core from the reusable housing.
3Reliability
If the atomizing core component is fully inserted into the installation space, then the sealing is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The atomizing core component is segmented into two parts of different lengths: the first part fits into the air duct and the second part fits into the insertion port. The second part protrudes outside the atomizing base, providing an exposed grip area that enables easy disassembly by pulling on the protruding portion without compromising the sealing provided by the first part inside the air duct.
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
Facilitates user-friendly replacement of the atomizing core component, reducing costs and environmental impact by allowing for simple pull-out installation and disassembly, eliminating the need for screw threads, and ensuring secure sealing and airflow communication.
Implementation Method 1
either the first part or the air duct is provided with a first seal to elastically attach to the other one. A second seal is provided either the second part or inner wall of the air duct, so as to elastically attach to the other one
Implementation Method 2
When the atomizing core component is installed on the atomizing base, the first part will be elastically interference-plug into the air duct, which makes the internal air of atomizing core component communicate with the internal air channel of the air duct

AI summary
The present disclosure discloses an atomizing device of an electronic cigarette that includes an atomizing base and an atomizing core component. The atomizing core component is configured to produce heat energy to atomize juice and is removably installed on the installation space along the insertion port of the atomizing base. When the atomizing core component is installed, the first part of the atomizing core component is plugged into the installation space, and the second part of the atomizing core component is configured to block the insertion port and at least part of the second part is exposed to the outside. When an external force is applied to the atomizing core component, the atomizing core component is configured to be pulled out along the insertion port driven by the at least part of the second part of the atomizing core component that is exposed to the outside.
