Atomizer One-Way Valve Structure for Low Inhalation Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic atomization devices face issues with high resistance at the valve opening due to large adhesive forces between the baffle and the base, leading to difficulty in inhalation and poor user experience.
Innovation Solution
The atomizer incorporates a one-way valve with a baffle that has a closed state and an open state, featuring a reduced contact area through annular grooves, recessed surfaces, and stress weak points to minimize adhesive forces, allowing the baffle to open with a small air pressure difference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve is disposed in the atomizer to prevent leakage of oil and liquid condensate, then the power supply assembly is protected from corrosion, but the resistance to valve opening becomes large, resulting in poor user experience
Solution Approach 1:
The baffle is designed as a flexible thin-walled structure that can elastically deform during operation. This flexibility allows the baffle to open easily with minimal suction force while maintaining its sealing function when closed, thus reducing the resistance to valve opening without compromising the protection function.
Solution Approach 2:
The patent extracts the harmful adhesive forces by creating a stress weak point in the form of an annular groove on the contact surface. This groove removes material that would otherwise contribute to adhesion, allowing the baffle to separate from the base more easily during inhalation while the baffle remains in place to prevent leakage.
2Ease of operation
If the contact area between the baffle and the base is reduced to minimize adhesive forces, then the valve opening resistance is reduced, but the sealing performance may be compromised
Solution Approach 1:
The contact surface of the base is designed with non-uniform properties: an annular groove creates a stress weak point with reduced material, while the surrounding contact areas maintain full contact for sealing. This local variation in quality allows easy opening at the groove location while maintaining sealing performance at the contact interfaces.
Solution Approach 2:
The baffle-base interface is designed to be dynamically adaptable. During normal conditions, the baffle maintains full contact with the base for sealing. During inhalation, the elastic baffle deforms and separates at the stress weak point, allowing easy opening. The system transitions between sealed and open states based on operational conditions.

AI summary
The atomizer is applied to an electronic atomization device. The atomizer includes an airflow channel, an atomizing core, a base, and a one-way valve comprising a baffle that is connected to the base. The baffle has a closed state and an open state. Under normal conditions, the baffle is in the closed state, the baffle covers the air inlet. Upon inhaling at the air outlet, the baffle is in the open state to allow airflow to pass through. The base and/or the baffle is provided with a cavity. While the baffle is in the closed state, surfaces on which the base and the baffle press against each other are contact surfaces, at least a part of the cavity is located on the contact surfaces, the cavity communicates with the air inlet to form a stress weak point.
