Solution Overview
Problem
Conventional electronic cigarettes lack a leakproof device, causing condensed e-liquid to permeate into the battery assembly and lead to short circuits.
Innovation Solution
The electronic cigarette incorporates an atomization assembly with a leakproof device comprising a piece of cotton, a heating wire, a limit cover, and seal rings to absorb and contain e-liquid, preventing it from flowing into the battery assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no leakproof device is provided in conventional electronic cigarettes, then the structure is simple, but condensed e-liquid permeates into the battery assembly causing short circuits
Solution Approach 1:
The patent employs seal rings (first seal ring, second seal ring, third seal ring) made of flexible sealing materials to create barrier films between the atomization assembly and battery assembly. These thin film structures effectively block e-liquid permeation while maintaining structural simplicity and avoiding short circuits.
Solution Approach 2:
The patent introduces an intermediary substance (absorbent material/cotton) between the heating wire and the battery assembly. This intermediary absorbs condensed e-liquid and prevents it from reaching the battery, resolving the contradiction by adding a simple mediating layer rather than complex structural modifications.
2Reliability
If seal rings and absorbent materials are added to create a leakproof device, then e-liquid permeation is prevented, but the number of components increases
Solution Approach 1:
The patent merges multiple sealing functions into a unified leakproof device structure that integrates the seal rings and absorbent materials into the existing atomization assembly. By combining these elements into a coordinated system rather than separate additions, the patent achieves effective leakproofing while minimizing the increase in component count.
Solution Approach 2:
The seal rings serve multiple functions: they seal the connection between the atomization assembly and battery assembly, prevent e-liquid permeation, and provide structural support. This multi-functionality reduces the need for additional dedicated components, thereby limiting the increase in device complexity while maintaining high leakproof performance.
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
The leakproof device effectively prevents e-liquid from entering the battery assembly, thereby avoiding short circuits and ensuring reliable operation of the electronic cigarette.
Implementation Method 1
The piece of cotton is disposed on the base to absorb deposited e-liquid on the base
Implementation Method 2
the limit cover is disposed on the piece of cotton to absorb condensed e-liquid on the limit cover
Implementation Method 3
the third seal ring encircles the base to seal the e-liquid tank
Implementation Method 4
The groove collects the condensed e-liquid of the atomization assembly, thus preventing the e-liquid from flowing into the battery assembly
