Rotating Locking Mechanism for E-Cigarette Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-cigarettes have complex and costly child locking structures that are inconvenient to operate, posing a challenge in preventing children from easily accessing the liquid storage chamber.
Innovation Solution
An atomizer and electronic cigarette design featuring a simple child locking mechanism with a movable upper cover assembly, locking member, and recesses that allow for easy rotation to lock or unlock the liquid storage chamber, ensuring safety and convenient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push-pull child locking structure is adopted, then children are prevented from easily opening the liquid storage chamber, but the structure becomes complicated and costly
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a locking member with locking protrusion, a movable member with recess, and a fixed member with locking groove. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while maintaining effective child locking capability.
Solution Approach 2:
The locking member is designed to be movable relative to the fixed member, transitioning between locked and unlocked states. The locking protrusion can move in and out of the locking groove based on user operation, providing dynamic locking control without requiring complex mechanical structures.
2Reliability
If a push-pull child locking structure is adopted, then children are prevented from easily opening the liquid storage chamber, but the operation becomes inconvenient
Solution Approach 1:
The locking mechanism is designed to be self-operating through a simple rotational motion. The movable member rotates to automatically engage or disengage the locking protrusion with the locking groove, eliminating the need for complex pushing or pulling actions and making the operation intuitive and convenient for users.
3Adaptability or versatility
If the liquid storage chamber is made openable for repeated liquid filling, then economic practicality is improved, but children can easily access the e-liquid
Solution Approach 1:
The child locking mechanism is activated by default, with the locking protrusion positioned to engage the locking groove before any opening operation. This preliminary anti-action prevents children from accidentally opening the chamber while allowing controlled access for liquid filling through the designated opening mechanism.

AI summary
An atomizer and an electronic cigarette comprising same. The atomizer (100) comprises an upper cover assembly (20) and a fixed component; the upper cover assembly (20) comprises an upper cover (21), a movable component (24) capable of rotating relative to the upper cover (21), and a locking component (22) movably provided between the upper cover (21) and the movable component (24); the movable component (24) is partially accommodated in the upper cover (21); a through hole (2122) is provided on the upper cover (21); a groove (2421) is provided on the movable component (24); the fixed component is sleeved at outside of the upper cover (21); a clamping groove corresponding to the through hole (2122) is provided on the fixed component; when the movable component (24) is rotated until the groove (2421) is staggered with the locking component (22), the locking component (22) partially penetrates through the through hole (2122) and is locked with the clamping groove. By providing the groove (2421) corresponding to the locking component (22) on the movable component (24), when the movable component (24) is rotated relative to the upper cover (21), the movable component (24) can abut against the locking component (22), so that the locking component (22) is provided at outside of the upper cover assembly (20) in a protruding mode and clamped in the clamping groove. The present invention is easy to operate and prevents a child from easily opening the atomizer to be in contact with an e-liquid.
