Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic atomizing devices face issues of liquid leakage and insufficient liquid supply due to the arrangement of the liquid inlet at the bottom of the reservoir, leading to imbalanced pressure and flow rates, affecting user experience.
Innovation Solution
A capillary liquid conducting and atomizing unit with a housing and atomization assembly featuring a capillary liquid absorbing channel that extends along the side of the atomization assembly, allowing liquid to be absorbed by capillary action, eliminating the need for the inlet to be at the bottom and ensuring consistent liquid supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the liquid inlet is arranged at the bottom of the liquid storage reservoir, then the liquid pressure at the liquid inlet is relatively large, but the liquid easily passes through the porous liquid conducting member causing liquid leakage
Solution Approach 1:
The patent introduces a capillary liquid absorbing channel as an intermediary structure between the liquid inlet and the porous liquid conducting member. This channel uses capillary action to transport liquid, acting as a mediator that controls liquid flow and prevents direct high-pressure liquid from overwhelming the porous material, thus solving the liquid leakage problem while maintaining adequate liquid supply pressure
2Object-generated harmful factors
If the pore size and pore density of the porous material are adjusted to solve liquid leakage, then liquid leakage is reduced, but the liquid supply speed becomes slower causing insufficient liquid supply and dry burning
Solution Approach 1:
The patent segments the liquid transport path into two distinct parts: the capillary liquid absorbing channel for primary liquid transport and the porous liquid conducting member for distribution. This segmentation allows the capillary channel to handle the bulk liquid flow at higher speed while the porous material focuses on distribution, preventing both leakage and insufficient supply
3Stress or pressure
If the liquid inlet is at the bottom, then liquid pressure is high for atomization, but as liquid level decreases the pressure becomes smaller causing slower liquid passage and dry burning
Solution Approach 1:
The patent replaces the gravity-dependent pressure system with a capillary action-based liquid transport system. The capillary liquid absorbing channel uses surface tension and capillary forces to draw liquid upward and maintain steady flow, eliminating the direct dependence on liquid level pressure variations, thus ensuring reliable and consistent liquid supply throughout the atomization process

Implementation Method 1
a capillary liquid absorbing channel communicating with the liquid inlet is provided between an inner side of the housing and a side of the atomization assembly where the liquid inlet is located; and a length direction of the capillary liquid absorbing channel extends along a height direction of the side where the liquid inlet is located, to absorb liquid into the liquid inlet by capillary action

AI summary
The disclosure provides a capillary liquid conducting and atomizing unit and an atomizing device. The capillary liquid conducting and atomizing unit includes a housing and an atomization assembly arranged in the housing; at least one liquid inlet is provided in a side of the atomization assembly, a capillary liquid absorbing channel communicating with the liquid inlet is provided between an inner side of the housing and the side where the liquid inlet is located; a length direction of the capillary liquid absorbing channel extends along a height direction of the side where the liquid inlet is located, and two opposite ends of the capillary liquid absorbing channel respectively extend towards an upper side and a lower side of the liquid inlet, to absorb liquid into the liquid inlet by capillary action. By arranging the capillary liquid absorbing channel outside the liquid inlet, the liquid outside the atomizing unit can be absorbed into the liquid inlet by capillary action, thus the liquid inlet is not required to be arranged at a bottom of the liquid storage reservoir and thus avoids the liquid leakage. Further, the liquid in the bottom of the liquid storage reservoir can be absorbed into the liquid inlet by capillary action to avoid the problem of dry burning caused by insufficient supply of liquid.
