Atomizer One-Way Valve Structure for Easier Inhalation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic atomization devices face difficulties in user inhalation due to high resistance at the valve opening, caused by the adhesive force between the baffle and the base, leading to a poor user experience.
Innovation Solution
The design incorporates a one-way valve with a baffle that has a closed and open state, featuring a stress weak point at the contact surfaces to reduce adhesive force, allowing airflow with a smaller air pressure difference, and includes a recessed annular groove and separation surfaces to minimize contact area and enhance baffle detachment.
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 contact surface between the baffle and base is segmented into multiple discrete contact points rather than a continuous surface. This is achieved by providing multiple protrusions on the baffle that contact corresponding recesses on the base, or by providing a circumferential gap between the baffle and base. This segmentation significantly reduces the total contact area and thus the adhesive force, allowing the valve to open easily during inhalation while still maintaining reliability when closed.
Solution Approach 2:
The contact surface between the baffle and base is made rough in specific local areas rather than being uniformly smooth. This is achieved by providing rough surfaces at the contact points between the baffle protrusions and base recesses. The rough local surfaces increase mechanical interlocking and friction, which enhances the sealing effect and prevents leakage, while the overall contact area remains small due to the segmented structure.
2Reliability
If the contact area between the baffle and base is increased to improve sealing, then leakage prevention is enhanced, but the adhesive force increases, making valve opening difficult
Solution Approach 1:
The contact interface is divided into multiple discrete contact points through protrusions and recesses, or through a circumferential gap structure. This segmentation reduces the total contact area while maintaining effective sealing at each contact point, thereby reducing the overall adhesive force that must be overcome to open the valve.
Solution Approach 2:
The contact surfaces at the discrete contact points are made rough to enhance local sealing effectiveness through mechanical interlocking and increased friction. This allows adequate sealing with minimal contact area, reducing the total adhesive force while maintaining leakage prevention capability.

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.
