Personal Vaporizer E-Liquid Reservoir Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal vaporizer systems suffer from contamination of e-liquid with particles such as tin, silver, iron, nickel, aluminum, and silicate, which can cause respiratory distress due to their exposure during the welding of components and chemical reactions with the atomizer.
Innovation Solution
A personal vaporizer system with a separate e-liquid reservoir made of high-grade steel, coated with food/surgical compatible materials, and a pressure-driven e-liquid feeding mechanism that isolates the e-liquid from the atomizer until vaporization, eliminating direct contact and potential contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional welding methods are used to assemble vaporizer components, then structural strength and reliability are improved, but metal particle contamination of e-liquid increases
Solution Approach 1:
The vaporizer is divided into separate modules: a heating module that can be pre-assembled and tested independently, and a liquid reservoir module that remains isolated until final assembly. This segmentation prevents contamination of the e-liquid during the welding process while maintaining structural integrity through controlled assembly stages.
Solution Approach 2:
A temporary protective barrier or sealing mechanism is introduced between the e-liquid and the welding zone. This intermediary prevents metal particles from reaching the e-liquid during assembly while allowing the welding process to proceed normally. The barrier is removed or bypassed only after welding is complete and the system is sealed.
2Device complexity
If e-liquid is stored in direct contact with atomizer components, then device complexity is reduced, but e-liquid degradation and contamination occur
Solution Approach 1:
The liquid storage system is separated from the heating/atomization system into distinct compartments. The e-liquid is stored in a sealed reservoir that only connects to the atomizer through a controlled delivery mechanism during operation. This segmentation protects the e-liquid from degradation while maintaining a relatively simple overall device structure through modular design.
Solution Approach 2:
The e-liquid is pre-filled and sealed in a protected reservoir before use. The connection between the reservoir and atomizer is established only when needed, preventing premature exposure to oxygen, heat, and metal surfaces that would cause degradation. This preliminary sealing action maintains e-liquid stability without requiring complex protective mechanisms throughout the device.
3Ease of operation
If permanent connection between e-liquid storage and atomizer is used, then ease of operation is improved, but exposure time to particles increases
Solution Approach 1:
The connection between the e-liquid reservoir and atomizer transitions from a permanent static connection to a dynamic controlled connection. The system allows the liquid pathway to be opened or closed based on operational needs, enabling continuous delivery when active while minimizing exposure time when inactive. This dynamic control reduces the duration of contact between e-liquid and potential contaminants without compromising operational convenience.
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 ensures the e-liquid remains fresh and free from metal contamination, maintaining its properties for a longer period without degradation, thereby reducing health risks and ensuring consistent vapor quality.
Implementation Method 1
the heating element vaporizes the atomized substance
Implementation Method 2
a wicking material that transport the liquid to the coil to be vaporized
Implementation Method 3
a hole that allows the passage of the e-liquid contained in the e-liquid reservoir to the atomizer compartment, caused from the difference of pressure between the inner part of said body of the vaporizer and the e-liquid reservoir

AI summary
The present application discloses a personal vaporizer system with an e-liquid reservoir isolated from the atomizer. The isolation of the e-liquid reservoir from the atomizer eliminates particles contamination of the e-liquid held in the reservoir and chemical reactions between the atomizer and the e-liquid. Since the residence time of “fresh” e-liquid in the atomizer is only the necessary to vaporize a very small amount of e-liquid, particles contamination of the produced vapor and chemical reactions between the e-liquid and atomizer components are dramatically reduced. This represents a huge health benefit for the consumer, compared to all others personal vaporizers with an e-liquid reservoir. The disclosed system can be used in any type of personal vaporizer, for example in the electronic cigarette market.
