Vaporization Assembly With Asymmetrical Channels for Bubble Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bubbles generated by ventilation tend to stay in and block the liquid flowing channels of vaporization assemblies, affecting ventilation performance and preventing liquid from entering the vaporization core.
Innovation Solution
The vaporization assembly features asymmetrical liquid flowing channels with guide grooves on the wall surface of one channel to destroy surface tension and utilize capillary force, guiding liquid towards the vaporization core while preventing bubbles from blocking the channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid flowing channels are provided in the mounting base for liquid to flow from the liquid storage cavity to the vaporization core, then liquid can be delivered to the vaporization core, but bubbles generated by ventilation will block the liquid flowing channels, preventing liquid from entering the vaporization core
Solution Approach 1:
The liquid flowing channels are divided into a first liquid flowing channel and a second liquid flowing channel. The first channel is designed with guide grooves to guide liquid flow, while the second channel is designed as a smooth channel to facilitate bubble rise and discharge. This segmentation allows different channels to handle different functions (liquid transport vs. bubble removal), resolving the contradiction between liquid delivery and ventilation performance.
Solution Approach 2:
Different surface qualities are applied to different channels: the first liquid flowing channel has guide grooves created on its inner surface to enhance liquid flow guidance, while the second liquid flowing channel maintains a smooth inner surface to reduce bubble adhesion and facilitate bubble rise. This local differentiation of surface properties optimizes each channel for its specific function, eliminating the blockage problem while ensuring reliable liquid delivery.
2Device complexity
If symmetrical liquid flowing channels are provided in the mounting base, then structural simplicity is maintained, but bubbles remain balanced and can block both channels equally, affecting liquid flow
Solution Approach 1:
The liquid flowing channels are designed with asymmetrical structures: the first channel includes guide grooves on its inner surface while the second channel has a smooth surface without grooves. This asymmetry creates different flow characteristics in each channel, allowing the grooved channel to effectively guide liquid while the smooth channel preferentially allows bubbles to rise and discharge, thereby improving liquid flow efficiency by preventing bubble blockages.

AI summary
A vaporization assembly includes: a vaporization sleeve having a liquid storage cavity for storing liquid; and a mounting base embedded in the vaporization sleeve, a first liquid flowing channel and a second liquid flowing channel being provided in the mounting base in a direction facing the liquid storage cavity. In the first liquid flowing channel and the second liquid flowing channel, a plurality of guide grooves are provided only on a wall surface of the first liquid flowing channel so as to cause the first liquid flowing channel and the second liquid flowing channel to be asymmetrical in structure.
