Conductive Contact Structure for Electronic Cigarette Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarette conductive contact structures are complex, prone to gaps, and easily damage the insulating member, leading to leakage of tobacco liquid into the power supply assembly, causing electrical damage and safety risks.
Innovation Solution
A conductive contact structure comprising a negative electrode assembly, a sealing element, and an insulating assembly, where the negative electrode passes through the cover body to abut against the sealing element, and the positive electrode partially passes through the insulating assembly and sealing element, enhancing sealing performance and preventing tobacco liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional conductive contact structure with multiple parts is used, then electrical connection is achieved, but gaps are easy to generate between parts causing poor sealing performance
Solution Approach 1:
The patent combines the sealing element and insulating assembly into an integrated structure where the sealing element is disposed between the positive electrode assembly and negative electrode assembly, and the insulating assembly covers the positive electrode assembly. This merging of sealing and insulating functions into a unified structure eliminates gaps between separate parts while maintaining electrical connection, directly resolving the contradiction between sealing performance and structural complexity.
2Reliability
If the conductive contact structure has many parts, then electrical connection is established, but the insulating member is easily damaged during welding causing short circuit
Solution Approach 1:
The patent segments the conductive contact structure into distinct functional modules: negative electrode assembly, sealing element, insulating assembly, and positive electrode assembly. The insulating assembly is specifically designed to cover the positive electrode assembly and prevent contact with the negative electrode assembly, isolating the welding process to specific areas and reducing the risk of insulating member damage during manufacturing.
3Reliability
If the conductive contact structure is complex, then electrical connection is achieved, but tobacco liquid leaks into the power supply assembly causing electrical damage
Solution Approach 1:
The patent introduces a sealing element as an intermediary component disposed between the positive electrode assembly and negative electrode assembly. This sealing element acts as a barrier that prevents tobacco liquid from leaking along the conductive contact structure into the power supply assembly, while still allowing the electrical connection to function. The insulating assembly also serves as an intermediary protective layer.

AI summary
The present disclosure provides a conductive contact structure for a power supply assembly. The power supply assembly includes a cover body, and a main body inbuilt with a master control board. The cover body and the main body define an installation space therebetween. The conductive contact structure includes a negative electrode assembly, a sealing element, an insulating assembly and a positive electrode assembly that are disposed in sequence in the installation space. The negative electrode assembly is configured for passing through the cover body to abut against the sealing element and defines a through hole. The insulating assembly has one end configured for covering the positive electrode assembly on the main body and has the other end abutting against the sealing element. The positive electrode assembly is configured for partially passing through the insulating assembly and the sealing element in sequence to be accommodated in the through hole.
