Atomizer Sleeve Structure for High-Viscosity Liquid Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaporization devices face poor vaporization effects due to the inability of high-viscosity liquid substrates to be smoothly absorbed by the vaporization core, especially when the device is miniaturized.
Innovation Solution
The vaporizer design includes a liquid storage tube with a sleeve and a vaporization core, where the distance between the first surface of the sleeve and the liquid storage tube is greater than the distance between the second surface, featuring a liquid guiding port on the first surface and a seal member with a liquid inlet hole, allowing for increased liquid feeding space and improved substrate delivery to the vaporization core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distance between the vaporization core and the side wall of the liquid storage tube is reduced to enable miniaturization, then the device size is reduced, but high-viscosity liquid substrates cannot be smoothly absorbed by the vaporization core
Solution Approach 1:
The patent introduces an asymmetric distance relationship between the sleeve surfaces and the liquid storage tube wall, creating an oblique liquid guiding port that directs liquid flow at an angle toward the vaporization core. This dimensional repositioning of the liquid flow path enables smooth delivery of high-viscosity liquids despite the constrained radial space in miniaturized devices.
Solution Approach 2:
The patent changes the geometric parameters of the liquid delivery system by creating an asymmetric configuration where the first distance (from liquid guiding port to vaporization core) is greater than the second distance (from opposite sleeve surface to liquid storage tube wall). This parameter optimization ensures adequate liquid flow path length for high-viscosity substrates while maintaining compact overall device dimensions.
2Ease of operation
If a liquid guiding port is introduced to improve liquid delivery, then high-viscosity liquid absorption is enhanced, but the device structure becomes more complex
Solution Approach 1:
The patent merges the liquid guiding function with the existing sleeve structure by forming the liquid guiding port on the sleeve's outer surface. The seal member is integrated into the same assembly, combining multiple functions (liquid guidance, sealing, and structural support) into a unified component system, thereby minimizing additional complexity.
Solution Approach 2:
The patent applies local quality modification by creating the liquid guiding port only at the specific location where liquid delivery is needed, rather than redesigning the entire device structure. The asymmetric distance configuration is applied locally to the sleeve-vaporization core interface, maintaining simplicity in other parts of the device.
