Atomizer Layout With Bottom Reservoir to Prevent E-Liquid Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizers in electronic cigarettes suffer from tobacco liquid spillage due to the liquid conductor becoming saturated and expelling liquid under gravity, leading to cumbersome usage and deteriorated user experience.
Innovation Solution
The atomizer design includes a liquid conductor with a main portion surrounding the heater and an extending portion that absorbs tobacco liquid from below, positioned such that it does not easily saturate, with the reservoir located below the gas pathway to prevent liquid deposition into the gas pathway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the liquid conductor transfers tobacco liquid from the lateral surface to the heater, then the tobacco liquid can be delivered to the heater for heating, but the liquid conductor becomes easy to saturate causing tobacco liquid to be expelled inadvertently under gravity force
Solution Approach 1:
The patent inverts the traditional liquid transfer direction by positioning the reservoir below the heater and having the liquid conductor extend upward to deliver liquid. This gravitational alignment prevents saturation and inadvertent expulsion while maintaining effective liquid delivery to the heater.
Solution Approach 2:
The liquid conductor is configured to extend in a vertical direction from the lower reservoir upward to the heater, changing the spatial dimension of liquid delivery. This vertical arrangement utilizes gravity favorably to prevent liquid accumulation and saturation in the conductor.
2Ease of manufacture
If the reservoir is positioned above the heater, then liquid delivery is straightforward, but tobacco liquid spills into the gas pathway deteriorating user experience
Solution Approach 1:
The patent inverts the conventional reservoir positioning by placing it below the heater instead of above. This inversion eliminates the harmful effect of liquid spillage into the gas pathway while maintaining reliable liquid delivery through the upward-extending liquid conductor.
Solution Approach 2:
The patent converts the potentially harmful effect of gravity (which causes liquid spillage when reservoir is above heater) into a beneficial effect by positioning the reservoir below the heater. Gravity now assists in preventing liquid accumulation and spillage while maintaining continuous liquid delivery to the heater.
3Quantity of substance
If the liquid conductor extends laterally to transfer liquid, then liquid can reach the heater, but the structure becomes cumbersome and complex
Solution Approach 1:
The patent simplifies the liquid conductor configuration by inverting the spatial arrangement - positioning the reservoir below the heater and having the conductor extend vertically upward. This eliminates the need for complex lateral routing and reduces overall structural complexity while maintaining effective liquid transfer.
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
This design effectively prevents tobacco liquid leakage by ensuring it settles into the reservoir, improving user experience by reducing spillage and enhancing the smooth operation of the electronic cigarette.
Implementation Method 1
a liquid conductor, extending towards the proximal end of the atomizing body to contact the heater in the gas pathway and extending towards the distal end of the atomizing body to absorb tobacco liquid from the reservoir
Implementation Method 2
a heater, configured for heating the tobacco liquid to generate an aerosol
Implementation Method 3
the atomizer transfers the tobacco liquid in the reservoir to the heater for heating and atomizing, exterior air flowing in through the gas-inlet pathway bears the atomized tobacco liquid, then expelled through the gas-outlet pathway to form the aerosol mist or vapour
