Atomizer Slide Cavity Mechanism for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic atomization devices have a simple mechanism for removing the atomization core, which can be easily accessed by children, leading to potential hazards such as accidental ingestion of the substrate.
Innovation Solution
The atomizer design includes a slide cavity within an inner barrel where the atomization core assembly is received, and a mouthpiece assembly that pushes the atomization core assembly to slide within the cavity, allowing the end of the atomization core to be exposed for removal, thus requiring special skills to disassemble.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple connection structure is used for the atomization core, then the ease of operation is improved, but the safety for vulnerable people deteriorates
Solution Approach 1:
The atomization core assembly is divided into separable components: the atomization core itself and a retaining structure. The retaining structure includes a retention member that engages with the inner barrel through a specific mechanism (such as a snap-fit or interference fit), requiring deliberate action to disengage. This segmentation allows the atomization core to be removed by adults who can perform the required manipulation while preventing accidental removal by children who cannot execute the disengagement sequence.
Solution Approach 2:
A retention member acts as an intermediary mechanism between the atomization core and the inner barrel. This intermediary component creates a controlled interface that requires specific manipulation (such as pushing, twisting, or pressing a release mechanism) to disengage. The retention member translates simple user input into the force needed to overcome the retention force, allowing easy removal for adults while presenting a barrier to children.
2Ease of operation
If the atomization core is easily accessible, then the ease of operation is improved, but the reliability deteriorates
Solution Approach 1:
The retention structure implements preliminary anti-action by pre-establishing a mechanical barrier (retention force) that opposes accidental removal. The retention member is pre-loaded or pre-positioned to engage with the inner barrel, creating an initial resistive force that must be overcome before the atomization core can be removed. This preliminary opposing force prevents unintended access while allowing deliberate removal when the user applies the correct manipulation sequence.
3Object-affected harmful factors
If a complex disassembly mechanism is used, then the safety for vulnerable people is improved, but the device complexity increases
Solution Approach 1:
The retention mechanism is segmented into simple, discrete components (retention member, retention cavity, inner barrel) rather than a complex integrated system. Each component has a single, well-defined function, and their interaction creates the protective effect. This segmentation maintains low device complexity while achieving safety through the cumulative effect of simple mechanical interactions.
Solution Approach 2:
The complex protective function is localized to a specific region (the retention interface between the retention member and inner barrel) rather than distributed throughout the entire device. The retention mechanism concentrates the safety function at the point where the atomization core interfaces with the inner barrel, keeping the rest of the device simple and maintaining overall low complexity while providing robust protection.

AI summary
An atomizer (100) includes: a liquid storage assembly (10), including an inner barrel (13), wherein the inner barrel defines a slide cavity (130), the slide cavity is defined for receiving the atomization core assembly (30); and a mouthpiece assembly (20), disposed at an end of the inner barrel (13) for pushing against the atomization core assembly, such that the atomization core assembly slides relative to the inner barrel, and an end of the atomization core assembly is exposed to an outside of the atomizer. By configuring the mouthpiece assembly to push against the atomization core assembly, the atomization core assembly slides along the slide cavity of the inner barrel, and one end of the atomization core assembly is exposed to the outside. Therefore, a risk of children removing the atomization core assembly and causing hazards to themselves may be reduced effectively.
