Conductive Contact Structure Sealing for E-Cigarette Battery Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conductive contact structures in electronic cigarette battery assemblies are complex and prone to oil leakage, leading to tobacco liquid penetration into the battery assembly, which can damage internal electrical components.
Innovation Solution
A conductive contact structure comprising a negative electrode assembly, a sealing member, and an insulating assembly, where the negative electrode assembly abuts against the sealing member through the cover body, and the positive electrode assembly partially passes through the insulating and sealing members, enhancing sealing performance and preventing liquid penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional conductive contact structure is used, then the atomizer can be connected to the battery assembly, but the structure is complicated and has many components which easily generate gaps
Solution Approach 1:
The patent combines multiple components (sealing member, insulating member, and conductive contact structure) into an integrated assembly where the sealing member and insulating member are positioned together to simultaneously provide sealing and insulation functions, reducing the number of separate components and assembly steps while improving reliability
Solution Approach 2:
The patent introduces a sealing member as an intermediary component between the atomizer and battery assembly that not only provides sealing but also incorporates insulating properties, thereby mediating both sealing and insulation requirements with a single component
2Reliability
If the conductive contact structure has many components, then electrical connection can be achieved, but gaps are easily generated between components allowing tobacco liquid penetration
Solution Approach 1:
The sealing member and insulating member are combined into a single integrated component that performs both sealing and insulation functions simultaneously, reducing the number of components from multiple separate parts to a unified structure that eliminates gaps between separate components
3Object-affected harmful factors
If the oil leakage preventing structure is weak, then the conductive contact structure remains simple, but tobacco liquid easily penetrates into the battery assembly
Solution Approach 1:
The sealing member is designed with composite functionality, combining sealing properties (to prevent liquid penetration) and insulating properties (to prevent electrical short circuits) in a single component, thereby resisting harmful liquid penetration without significantly increasing structural complexity

AI summary
A conductive contact structure, a battery assembly and an electronic cigarette are disclosed. The battery assembly 100 comprises a cover body 50 and a main body 30 in which a main control board 90 is built. The conductive contact structure comprises a negative electrode assembly (11), a sealing member 14, an insulating assembly 13 and a positive electrode assembly 12, which are provided sequentially. The negative electrode assembly passes through the cover body 50 to abut against the sealing member 14, and is provided with a through-hole 1111 in which an external load is installed. One end of the insulating assembly 13 covers the positive electrode assembly 12, and the other end abuts against the sealing member 14. The positive electrode assembly 12 partially passes through the insulating assembly 13 and the sealing member 14 sequentially, and is received in the through-hole. The technical solution of the present disclosure effectively improves the sealing performance of the conductive contact structure and avoids that tobacco liquid penetrates into the battery assembly from the conductive contact structure.
