E-Cigarette Vaporization Core With Segmented Liquid Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-cigarettes often experience phenomena such as 'e-liquid frying' and 'burnt core' due to incomplete vaporization of e-liquid, leading to a compromised taste of the smoke.
Innovation Solution
A vaporization core design with a liquid guide body having a specific liquid storage amount and structure, where the liquid guide portion is defined between the first and second side surfaces, and a heating body at the vaporization region, ensuring balanced vaporization and preventing unvaporized e-liquid from being inhaled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the liquid storage amount in the vaporization core is increased, then the vaporization liquid supply is sufficient to avoid burnt core, but the unvaporized e-liquid gathers in non-vaporization regions causing e-liquid frying
Solution Approach 1:
The liquid guide body is divided into distinct functional regions: a liquid absorbing region at the first side surface, a liquid guide portion in the middle, and a vaporization region at the second side surface. This segmentation ensures that e-liquid is absorbed at one end, guided through a controlled path, and vaporized at the other end, preventing accumulation in non-vaporization zones while maintaining sufficient liquid supply.
Solution Approach 2:
Different regions of the liquid guide body are assigned different properties: the liquid absorbing region has high porosity for liquid uptake, the liquid guide portion has controlled dimensions (1mm to 4mm translation distance) for precise liquid transport, and the vaporization region is positioned directly over the heating body for efficient vaporization. This local differentiation optimizes each zone's function to prevent both burnt core and e-liquid frying.
2Quantity of substance
If the liquid guide portion length is increased, then more e-liquid can be transported to the vaporization region, but the temperature cannot reach vaporization temperature causing incomplete vaporization
Solution Approach 1:
The patent specifies precise parameter ranges for the liquid guide portion: the translation distance from the first side surface to the second side surface is controlled at 1mm to 4mm, and the liquid storage amount Q2 is controlled at 19.3mg to 88.2mg (or 20.62mg to 55.39mg). These parameter optimizations ensure the liquid guide portion is long enough to transport sufficient e-liquid but short enough to maintain vaporization temperature, achieving complete vaporization.
3Quantity of substance
If the heating power is increased to vaporize more e-liquid, then the vaporization amount is sufficient, but the unvaporized e-liquid in non-vaporization regions is heated causing burnt core
Solution Approach 1:
The design extracts and eliminates non-vaporization regions from the heating zone. The liquid guide portion is positioned such that it does not directly contact the heating body, creating a thermal barrier that prevents heat from reaching e-liquid in the transport region. Only e-liquid in the vaporization region, directly over the heating body, is heated and vaporized, preventing burnt core while maintaining sufficient vaporization output.
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 solution effectively prevents 'e-liquid frying' and 'burnt core' by ensuring full vaporization of the e-liquid, improving the taste and quality of the smoke output.
Implementation Method 1
a liquid guide body (1), the liquid guide body having a first side surface (11) and a second side surface (12) arranged opposite to each other, at least a part of the first side surface forming a liquid absorbing region
Implementation Method 2
a heating body (2) arranged at the vaporization region of the second side surface (12)... the vaporization liquid is heated and vaporized by the vaporization core
Implementation Method 3
The vaporization liquid is heated and vaporized by the vaporization core to form smoke
