Electronic Cigarette Atomizer Child-Resistant Sealing Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refillable atomizers for electronic cigarettes pose a risk to children as they can easily remove the sealing cover, leading to potential ingestion of tobacco liquid, and existing designs fail to effectively prevent this and leakage.
Innovation Solution
An atomizer design featuring a sealing cover with a spring-loaded mechanism and protrusions/grooves that requires an external force to detach, preventing accidental removal by children and ensuring the cover only comes off when intentionally unscrewed, thus preventing liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing cover is used to seal the liquid injecting opening, then liquid leakage is prevented, but children can easily screw off the sealing cover and drink the tobacco liquid
Solution Approach 1:
The sealing cover is divided into two separate parts: a main body and a protective cover. The protective cover contains protrusions that engage with grooves on the main body, creating a child-resistant mechanism. This segmentation allows the seal to remain effective while preventing easy removal by children.
Solution Approach 2:
The protective cover is designed to fit over the main body of the sealing cover, with protrusions on the protective cover nesting into corresponding grooves on the main body. This nested structure creates a mechanical interlock that requires significant force to disengage, preventing children from easily removing the seal.
2Object-affected harmful factors
If a child-resistant mechanism is added to the sealing cover, then child safety is improved, but the device complexity increases
Solution Approach 1:
By dividing the sealing cover into two simple components (main body and protective cover) with basic geometric features (protrusions and grooves), the child-resistant mechanism is achieved without requiring complex internal structures or multiple moving parts.
Solution Approach 2:
Instead of making the main body complex and adding simple protective features, the design inverts the approach by keeping both components relatively simple and achieving the child-resistant function through the interaction of basic protrusion-groove geometry. This simplifies manufacturing and assembly.

AI summary
An exemplary atomizer includes a housing, a sealing cover, an atomizing element, an air passage, and an liquid injecting opening. The housing has a first end and an opposite second end. The second end is configured for connecting with a power supply. The housing defines a liquid chamber configured for containing tobacco liquid. The sealing cover is threadedly coupled with the first end. The atomizing element is configured for atomizing the tobacco liquid to form aerosol. The liquid injecting opening is defined in the first end. The sealing cover is configured for sealing the liquid injecting opening. The sealing cover includes a device configured for preventing children from screwing off the sealing cover. The sealing cover can be screwed off via an outer surface thereof only when an external force is exerted on the device to change an internal structural relationship of the device.
