Solution Overview
Problem
Conventional electronic cigarettes face issues with e-liquid solidification and non-uniform preheating leading to passage blockages, especially in cold conditions, and existing preheating methods do not adequately address these issues.
Innovation Solution
An electronic cigarette design incorporating a preheater with a heating wire in the e-liquid tank, an air duct, and a ceramic core for uniform preheating and atomization, along with insulation components and dual control circuits for precise e-liquid preheating and atomization control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If e-liquid is preheated before flowing into the atomization core, then the e-liquid flow blocking issue is addressed, but the preheating is non-uniform which may still cause blocking
Solution Approach 1:
The heating process is divided into two independent stages: preheating stage using a heating wire in the e-liquid tank, and atomization stage using a ceramic core in the atomization chamber. This segmentation allows each component to perform its specific function optimally without interfering with the other, ensuring both preheating effectiveness and atomization uniformity.
Solution Approach 2:
A valve mechanism serves as an intermediary between the preheating system and the atomization system. It controls the timing and flow of preheated e-liquid to the atomization core, ensuring that only properly heated e-liquid proceeds to the atomization chamber, thereby maintaining flow continuity and preventing blocking.
2Temperature
If a heating wire is used to preheat e-liquid, then the e-liquid can be heated before atomization, but the heating may not be uniform throughout the e-liquid
Solution Approach 1:
The e-liquid is preheated in advance within the tank using the heating wire before being transferred to the atomization chamber. This preliminary heating action ensures that the e-liquid reaches an appropriate temperature state prior to atomization, preventing blocking and ensuring smooth flow while the ceramic core then completes the heating and atomization process uniformly.
3Productivity
If e-liquid is heated directly in the atomization core, then atomization occurs, but the e-liquid may solidify in cold conditions before reaching the core
Solution Approach 1:
The system performs preliminary heating of the e-liquid in the tank using the heating wire before the e-liquid reaches the atomization chamber. This advance heating action prevents the e-liquid from solidifying in cold conditions, ensuring it remains in a flowable state and can be efficiently atomized by the ceramic core without blocking the passage.
