Atomizer One-Way Valve Structure for Leak Isolation and Reflux Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices face issues with liquid leakage from the liquid-storing chamber of the atomizer, which can lead to pollution and damage of internal components, particularly the airflow sensor and battery, due to air pressure changes during transportation or use.
Innovation Solution
The atomizer incorporates an air intake valve, a gulp valve, and a mouthpiece valve, all of which are one-way valves, to manage airflow and prevent liquid leakage. The air intake valve is designed to store leaked liquid, while the gulp valve maintains air pressure in the liquid-storing chamber, and the mouthpiece valve controls aerosol flow, preventing reflux and ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vent hole is provided at the bottom of the atomizer to communicate with the airflow sensor, then the electronic atomization device can be started by detecting airflow changes, but liquid leakage can occur during transportation or use due to air pressure changes, causing liquid to enter the controller and pollute or damage the airflow sensor or battery
Solution Approach 1:
The invention segments the internal space by introducing a baffle plate that divides the housing into a first space (containing the liquid storage chamber) and a second space (containing the controller). This segmentation prevents liquid from crossing from the first space to the second space, thereby protecting the controller and its components from liquid damage while maintaining the vent hole functionality for airflow detection
Solution Approach 2:
The baffle plate acts as an intermediary barrier between the liquid storage chamber and the controller. It allows air pressure equalization and airflow detection to occur through the vent hole while physically blocking liquid from reaching the controller, thus mediating between the need for pressure communication and liquid protection
2Reliability
If the liquid-storing chamber is sealed to prevent leakage, then liquid protection is improved, but air pressure changes during transportation or use can cause liquid to be forced out through any available path, potentially damaging components
Solution Approach 1:
By dividing the housing into separate spaces with a baffle plate, the invention creates a contained environment where pressure changes can occur in the first space without forcing liquid across the baffle plate into the second space. The segmentation provides a pressure buffer zone
Solution Approach 2:
The baffle plate provides beforehand protection by creating a physical barrier that cushions against pressure-induced liquid ejection. Even when pressure forces liquid against the baffle plate, the barrier prevents liquid from reaching the controller, thus cushioning the system against potential damage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents liquid from reaching and damaging internal components, maintains air pressure for efficient atomization, and reduces aerosol reflux, thereby enhancing the reliability and performance of the electronic atomization device.
Implementation Method 1
The air intake valve is opened when pressure of the air inlet portion of the air intake valve is greater than pressure of the air outlet portion of the air intake valve in the airflow channel by at least 100 pa
Implementation Method 2
The air intake valve, the gulp valve, and the mouthpiece valve are all one-way valves

AI summary
This disclosure discloses an atomizer and an electronic atomization device. The atomizer includes: a housing, provided with an air inlet and an air outlet; an airflow channel, formed in the housing and running through the air inlet and the air outlet; a liquid-storing chamber, disposed in the housing; a atomization assembly, disposed in the airflow channel and in fluid communication with the liquid-storing chamber; and an air intake valve, disposed in the airflow channel between the air inlet and the atomization assembly, where an air outlet portion of the air intake valve is close to the atomization assembly, an air inlet portion of the air intake valve is away from the atomization assembly, and a leaked liquid storage for storing leaked liquid is formed between the air intake valve and the atomization assembly; In the atomizer of this disclosure, even if fluid in the liquid-storing chamber leaks through the atomization assembly, the liquid will accumulate in the leaked liquid storage rather than being leaked through the air intake valve, thereby preventing the leaked liquid from polluting and damaging other elements after leaked from the air inlet. After inhalation is completed, the air intake valve can prevent occurrence of aerosol reflux.
