Vaporization Top Base Channel Layout for Bubble-Resistant Liquid Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic vaporization devices, excessive bubbles formed by high viscosity aerosol-generation substrates obstruct liquid feeding channels, leading to blocked liquid absorption and dry burning of the vaporization core, affecting user experience and device lifespan.
Innovation Solution
A vaporization top base with at least two liquid feeding channels, featuring a first corner close to the central axis and a second corner away from it, arranged upstream in the inlet direction, along with a protruding stage and air guide channel, to enlarge the exit and improve liquid feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If external air enters the liquid storage cavity through the vaporization core, then the vaporization process can be maintained, but bubbles form and obstruct the liquid feeding channel due to high viscosity of the aerosol-generation substrate
Solution Approach 1:
The liquid feeding channel is segmented into multiple sections with different cross-sectional areas. The channel includes a first section with a first cross-sectional area and a second section with a second cross-sectional area that is larger than the first. This segmentation allows bubbles to expand and move from the narrower first section to the wider second section, preventing obstruction while maintaining vaporization efficiency.
Solution Approach 2:
The liquid feeding channel transitions from a two-dimensional cross-section to a three-dimensional expanding structure. By increasing the cross-sectional area along the flow direction, the channel provides an additional spatial dimension for bubbles to expand and redirect, allowing them to escape the feeding channel without blocking liquid supply to the vaporization core.
2Duration of action of moving object
If bubbles gather above the liquid absorbing surface, then liquid absorption is blocked, but the vaporization core continues to operate requiring liquid supply
Solution Approach 1:
The liquid feeding channel is designed with an expanding cross-sectional area before the liquid reaches the vaporization core. This preliminary expansion creates a bubble expansion chamber that prevents bubbles from reaching and blocking the liquid absorbing surface, ensuring continuous liquid supply and preventing dry burning throughout the vaporizer's service life.
Solution Approach 2:
The expanded cross-sectional area section acts as an intermediary chamber between the liquid storage cavity and the vaporization core. This intermediate space allows bubbles to be captured and redirected away from the liquid absorption path, mediating between the incoming air-liquid mixture and the vaporization core to prevent blocking.
3Ease of manufacture
If the liquid feeding channel has a uniform cross-section, then the structure is simple, but bubbles cannot escape and cause dry burning
Solution Approach 1:
The liquid feeding channel has different local qualities in terms of cross-sectional area. The first section has a smaller cross-sectional area for efficient liquid transport, while the second section has a larger cross-sectional area for bubble expansion and escape. This local variation in geometry prevents dry burning while maintaining manufacturing feasibility through standard molding techniques.
