Inhaler Atomization Assembly Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inhalers, including electronic cigarettes and medical aerosol inhalers, suffer from the issue of volatile substances evaporating from the wick, leading to reduced efficacy and taste degradation when not in use due to direct communication between the liquid storage chamber and the outside environment.
Innovation Solution
An inhaler with a detachable atomization assembly that includes a liquid reservoir, an atomizing core, and a movable member, where the movable member seals the liquid reservoir when not in use, preventing liquid from reaching the wick, and communicates with the wick only when the assembly is connected to the battery, allowing for controlled liquid absorption and atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the liquid storage chamber is in direct communication with the wick, then the liquid can be continuously supplied to the atomizing core, but the volatile substances in the liquid will evaporate through the mouthpiece when not in use, leading to reduced efficacy and taste degradation
Solution Approach 1:
The movable member dynamically changes the communication state between the liquid storage chamber and the wick based on whether the inhaler is in use. When connected to the battery assembly, the movable member opens to allow liquid flow; when disconnected, it closes to seal the liquid storage chamber, preventing volatilization while maintaining liquid supply capability during operation.
Solution Approach 2:
The movable member acts as an intermediary component between the liquid storage chamber and the wick. It controls the liquid flow path by opening or closing the communication channel, serving as a gatekeeper that allows liquid to reach the wick only when needed, thereby preventing direct continuous exposure of the liquid to the atmosphere through the wick.
2Loss of substance
If a movable member is added to seal the liquid reservoir, then liquid volatilization is prevented, but the device structure becomes more complex
Solution Approach 1:
The movable member is integrated into the existing detachable connection system between the atomization assembly and battery assembly. It serves dual functions: sealing the liquid storage chamber when disconnected and allowing liquid flow when connected, without requiring a separate independent sealing mechanism. This multi-functionality reduces overall device complexity despite adding the sealing capability.
Solution Approach 2:
The movable member is positioned and actuated by the natural connection and disconnection actions of the user. When the user attaches or detaches the atomization assembly from the battery assembly, the movable member automatically moves to the appropriate position (open or closed) without requiring additional controls or mechanisms, making the system self-regulating.
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
Prevents volatilization of the liquid in the storage chamber when not in use, maintaining the quality and efficacy of the liquid, and ensuring consistent performance upon reactivation.
Implementation Method 1
when the atomization assembly is not connected to the battery assembly, the movable member seals the liquid reservoir, such that the liquid in the liquid reservoir is isolated from the wick
Implementation Method 2
the atomizing core includes a wick... one end of the liquid-draining aperture is in communication with the liquid storage chamber; when the atomization assembly is connected to the battery assembly, the movable member moves towards the battery assembly, such that the other end of the liquid-draining aperture is in communication with the wick
Implementation Method 3
the atomization assembly of the inhaler further comprises an elastic member, one end of the elastic member is connected to the movable member, the other end of the elastic member is connected to the liquid reservoir, a direction of urging the movable member by the elastic member is opposite to a moving direction of the movable member when the movable member moves towards the battery assembly
Implementation Method 4
at least part of the movable member is made of a magnetic material, the movable member is capable of being attracted by a magnet in the battery assembly to move towards the battery assembly

AI summary
An atomization assembly of an inhaler includes: a liquid reservoir defining a main liquid storage chamber therein for storing liquid and an auxiliary liquid storage chamber, the liquid reservoir further defining a liquid-draining aperture between the main liquid storage chamber and the auxiliary liquid storage chamber; an atomizing core connected to the liquid reservoir; and a movable member configured to move back and forth between a first position towards the liquid-draining aperture and a second position away from the liquid-draining aperture, wherein when the movable member is in the first position, the movable member seals the liquid-draining aperture, such that the main liquid storage chamber is isolated from the auxiliary liquid storage chamber; when the movable member is in the second position, the movable member is separated from the liquid-draining aperture, thereby communicating the main liquid storage chamber with the auxiliary liquid storage chamber.
