Ventilation Assembly for Electronic Cigarette Liquid Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette atomizers are inconvenient for liquid injection, prone to contamination, and experience poor contact stability due to frequent disassembly, leading to excessive liquid in the atomizing head and potential oil boiling, affecting user experience.
Innovation Solution
A ventilation assembly with isolated inlet passages and liquid injection channels, featuring an injection hole for convenient liquid addition and an exhaust port to manage air pressure, ensuring stable internal pressure and preventing excessive liquid in the atomizing head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the atomizing head is disassembled for liquid injection, then liquid can be injected into the atomizer, but the liquid injection process becomes inconvenient and the atomizing head is prone to contamination
Solution Approach 1:
The invention separates the liquid injection function from the atomizing head by providing a dedicated liquid injection channel that is isolated from the atomizing components. This allows liquid to be injected through a separate pathway without disassembling the atomizing head, thereby maintaining its integrity and preventing contamination while enabling convenient liquid refilling.
2Ease of operation
If the atomizing head is frequently removed for liquid injection, then liquid can be added, but poor contact between the atomizing head and other components occurs
Solution Approach 1:
The invention divides the liquid delivery system into separate functional channels: a liquid injection channel for refilling and an atomizing channel for vaporization. This segmentation allows the atomizing head to remain permanently installed and maintain stable contact with other components, while liquid can be added through the isolated injection channel without requiring disassembly.
3Reliability
If air is pressed into the liquid storage device during assembly, then the atomizer can be sealed, but high closed air pressure forces excessive cigarette liquid to the atomizing head
Solution Approach 1:
The invention provides separate isolated channels for liquid injection and air venting. The air venting channel allows trapped air to escape during assembly without pressurizing the liquid storage device, preventing excessive liquid from being forced into the atomizing head. Meanwhile, the liquid injection channel remains sealed and isolated, maintaining proper liquid levels without over-pressurization effects.
4Quantity of substance
If excessive cigarette liquid is in the atomizing head, then liquid can be supplied adequately, but oil boiling occurs and user experience is affected
Solution Approach 1:
The invention separates the liquid injection function from the atomizing head through an isolated injection channel, enabling precise liquid dosage control. This segmentation prevents overfilling by allowing liquid to be injected directly into the storage device without pressurization, ensuring adequate liquid supply to the atomizing head while preventing excessive liquid accumulation that would cause oil boiling and inhalation hazards.

AI summary
The ventilation assembly for an atomizer in an electronic cigarette has a storage chamber, which includes an inlet passages and a liquid injection channel located therein. The inlet passages and the liquid injection channel are isolated from each other. The ventilation assembly further includes an injection hole, an air inlet, the injection hole is in communication with the liquid injection channel and the storage chamber sequentially; and an exhaust port, the exhaust port, and the air inlet are in communication with the inlet passages; when need to inject cigarette liquid, open the injection hole and inject the cigarette liquid into the storage chamber through the injection hole; after the liquid injection is completed, during closing the injection hole, air received in the storage chamber is discharged from the injection hole, exhaust port, the air inlet passage and the air inlet successively.
