Soft One-Way Valve Structure for Cleaner E-Cigarette Atomizers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from staining due to reverse airflow and saliva entering the atomizer when the user blows air, which causes e-liquid to be squeezed out.
Innovation Solution
An electronic cigarette design incorporating a one-way valve made of soft materials like silicone or latex, featuring a hollow cylinder with an inner protrusion and an inverted V-shaped upper part with a slot, allowing forward airflow while preventing reverse airflow by automatically closing the slot under reverse pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air passage is opened for user inhalation, then the user can draw vapor from the atomizer, but reverse airflow and saliva can enter the atomizer and squeeze out e-liquid causing staining
Solution Approach 1:
A one-way valve is introduced as an intermediary component in the air passage to selectively allow forward airflow (user inhalation) while blocking reverse airflow and saliva. The valve acts as a mediator that permits vapor extraction in the forward direction but prevents contamination from reverse flow, thereby resolving the contradiction between ease of operation and protection against harmful factors.
Solution Approach 2:
The harmful reverse airflow and saliva are effectively extracted or removed from the system by the one-way valve, which isolates the atomizer from contamination. The valve extracts the problematic reverse flow while maintaining the necessary forward flow for user inhalation, thus protecting the e-liquid from being squeezed out.
2Object-affected harmful factors
If a one-way valve is added to prevent reverse airflow, then contamination is prevented, but the device structure becomes more complex
Solution Approach 1:
The one-way valve is constructed using flexible materials such as silicone rubber or latex, forming a thin film structure that can deform elastically. This flexible membrane allows forward airflow while automatically closing to block reverse airflow, achieving the protective function without requiring complex mechanical components, thereby minimizing the increase in device complexity.
Solution Approach 2:
The one-way valve employs a dynamic structure where the flexible membrane can move and deform in response to airflow direction. During forward inhalation, the membrane remains open; during reverse flow, it closes automatically. This dynamic behavior provides effective reverse flow prevention through a simple, adaptable structure rather than complex fixed mechanisms.

Function Achieved in This Case
Effectively prevents reverse airflow and saliva from entering the atomizer, thereby preventing e-liquid from being squeezed out and maintaining the electronic cigarette's cleanliness.
Implementation Method 1
the one-way valve comprises a soft material; when in use, a forward airflow is passable through the one-way valve, and a reverse airflow is unpassable through the one-way valve
