Rotating Locking Piece for Child-Resistant Atomizer Core Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing detachable atomization core assemblies in aerosol generators are prone to accidental removal by children or users due to simple connections, leading to potential safety hazards such as oil leakage.
Innovation Solution
An electronic atomization device with a locking piece that rotates to block or unlock the atomization core assembly, featuring a rotating column and clamping part to secure the assembly in place, and a baffle plate to prevent accidental disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the atomization core assembly is detachably assembled in the atomization device using simple connection methods (interference fit or threaded connection), then the atomization core assembly can be easily removed for replacement, but the assembly is prone to accidental removal by children or users leading to safety hazards
Solution Approach 1:
The locking piece is designed to rotate between a locked position (protruding to block the atomization core assembly) and an unlocked position (retracting to allow removal). This dynamic state change enables the structure to adapt between safety and ease of replacement based on operational context
Solution Approach 2:
The locking piece acts as an intermediary component between the atomization core assembly and the shell. It mediates the connection by providing an additional locking mechanism that requires intentional action to disengage, preventing accidental removal while maintaining intended functionality
2Reliability
If the locking piece structure is added to prevent accidental removal, then safety is improved, but the device complexity increases
Solution Approach 1:
The locking piece serves multiple functions: it blocks the atomization core assembly when protruding, rotates to unlock when retracted, and integrates with both the shell and atomization core assembly. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall device complexity
Solution Approach 2:
The locking piece is nested within the shell structure, rotating around the mounting hole axis. The clamping part nests within the shell's internal cavity, and the shielding part nests within the mounting hole. This nested arrangement minimizes the space occupied and integrates the locking mechanism into the existing structure rather than adding external complexity

AI summary
Electronic atomization device and an aerosol generator. The electronic atomization device includes a shell (1), an atomization core assembly (2), and a locking piece (3). The atomization core assembly is detachably mounted in the mounting hole (12). The first end of the locking piece is rotationally connected with an open end of the mounting hole, and the second end of the locking piece is detachably connected with the shell. When the first end rotates to the second end and connects to the shell, the locking piece partially protrudes in the mounting direction of the atomization core assembly and blocks the atomization core assembly from moving in the mounting direction. When the second end is disconnected from the shell and rotates around the first end in the direction away from the shell, the locking piece unlocks the atomization core assembly.
