Magnetic Drive Pumping Apparatus for Electronic Cigarette Liquid Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette systems face inefficiencies due to uncontrolled liquid delivery to the heating element, leading to issues like dry burning or insufficient atomization, and are bulky and difficult to manufacture due to separate micro-pump and liquid tank components connected by conduits, which increases the risk of leakage.
Innovation Solution
A magnetic drive pumping apparatus integrated with the liquid storage element, featuring a small-sized non-linear flow channel and low-voltage operation, allowing for efficient and controlled liquid delivery by eliminating external conduits and enhancing integration and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If micro-pump components are separated from the liquid tank and connected through conduits, then the micro-pump can be positioned independently, but the overall device size increases and the risk of liquid leakage increases
Solution Approach 1:
The patent integrates the micro-pump components directly into the liquid tank structure, eliminating separate conduits and sealing apparatus. The pump chamber is formed within the tank body, and the diaphragm is directly coupled to the tank wall, merging previously separate components into a unified structure that reduces overall device volume while maintaining independent positioning capability.
2Adaptability or versatility
If micro-pump components are separated and connected through conduits, then the micro-pump can be positioned independently, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the liquid tank and micro-pump into a single integrated unit, eliminating the need for multiple conduits, seals, and connection apparatus. The pump chamber is formed as an integral part of the tank, and fluid communication is achieved through direct openings rather than external conduits, significantly reducing device complexity.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components (conduits, seals, connection apparatus) from the system by directly integrating the pump function into the tank structure, simplifying the overall device architecture while maintaining the essential function of independent pump positioning.
3Device complexity
If conventional siphoning or wicking is used for liquid delivery, then the structure is simple, but the liquid delivery volume cannot be controlled leading to heating inefficiencies
Solution Approach 1:
The patent replaces passive mechanical liquid delivery mechanisms (siphoning, wicking) with an active magnetic drive system. The magnetic drive assembly uses magnetic fields to control the diaphragm movement, enabling precise control of liquid delivery volume while maintaining relatively simple device structure through the integration of the magnetic driver directly into the tank wall.
4Productivity
If magnetic drive micro-pump is used, then liquid pumping efficiency and response time improve, but power consumption increases
Solution Approach 1:
The patent merges the magnetic drive assembly directly into the liquid tank wall, eliminating the need for external drive mechanisms and long drive shafts. This integration reduces mechanical losses and improves coupling efficiency between the magnetic driver and diaphragm, enhancing pumping efficiency while reducing the power required to drive the system.
