Atomizer With Separated Smoke And Intake Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette atomizers produce large-particle smoke that can cause bad taste and scalding, and the integrated liquid storage structure leads to liquid leakage during transportation or use, potentially causing users to inhale the liquid.
Innovation Solution
The atomizer design includes an atomization compartment housing with a smoke passage and an intake passage that are separate, allowing atomized liquid to flow through a negative pressure-formed opening and preventing large-particle smoke from being inhaled, while the liquid storage is isolated to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the atomizer and electronic cigarette liquid storage structure are integrated, then the device structure is simplified, but large-particle smoke is produced causing bad taste and potential scalding
Solution Approach 1:
The patent divides the integrated structure into separate functional modules: an atomization chamber for vapor generation and a liquid storage chamber for e-liquid containment. This segmentation allows independent optimization of each module, enabling fine particle generation in the atomization chamber while preventing liquid leakage from the storage chamber, thereby resolving the contradiction between structural simplicity and harmful particle production.
Solution Approach 2:
The patent extracts the liquid storage function from the atomization process by providing a separate liquid storage chamber that communicates with the atomization chamber through controlled pathways. This extraction ensures that liquid is only transferred when needed for atomization, preventing both large-particle formation and unauthorized liquid access, thus resolving the harmful effects while maintaining functional integration.
2Device complexity
If the atomizer and electronic cigarette liquid storage structure are integrated, then the device structure is simplified, but liquid leakage occurs during transportation or use
Solution Approach 1:
The patent segments the liquid containment system into a dedicated storage chamber separated from the atomization chamber. This segmentation allows the storage chamber to be designed with leak-proof features independent of the atomization process, improving reliability during transportation while maintaining overall device simplicity through modular design.
Solution Approach 2:
The patent extracts the liquid storage function into a separate chamber that communicates with the atomization chamber only through controlled pathways. This extraction enables independent design of leak prevention mechanisms in the storage chamber, such as sealed compartments and controlled release pathways, thereby improving reliability without significantly increasing device complexity.
3Ease of operation
If the air inlet communicates with the outside air, then the user can inhale through the device, but the user may mistake the air inlet for the nozzle and suck electronic cigarette liquid
Solution Approach 1:
The patent extracts the air inlet communication pathway from direct access to the liquid storage chamber by introducing an atomization chamber as an intermediate stage. Air enters through the air inlet, passes through the atomization chamber where liquid is vaporized, and exits through the nozzle. This extraction ensures that even if users mistake the air inlet for the nozzle, they can only inhale vaporized liquid, not raw liquid, thereby maintaining ease of operation while eliminating liquid inhalation risk.
Solution Approach 2:
The patent introduces the atomization chamber as an intermediary between the air inlet and the liquid storage system. This intermediary transforms the physical state of liquid from liquid to vapor before it can be inhaled, acting as a protective barrier that prevents direct liquid contact while maintaining normal inhalation function. The intermediary ensures that only atomized vapor, not liquid, can reach the user regardless of which opening they use.
