Atomizer Suction Nozzle Anti-Child Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic atomizers are easily disassembled, posing a risk of accidental swallowing by children, as they can be inadvertently broken apart, allowing liquid medium to be ingested.
Innovation Solution
The design incorporates a suction nozzle unit with a cylindrical operating member and elastic member that requires a specific sequence of axial movement and rotation to transmit torsional force, making it difficult for children to disassemble the atomizer, featuring a second pipe with limiting portions and an elastic member to securely seal the liquid injection port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the atomizer is designed to be easily disassembled for refilling, then the ease of operation is improved, but the safety against accidental swallowing by children deteriorates
Solution Approach 1:
The operating member is designed to dynamically change the connection state between the suction nozzle unit and main body unit. By moving axially between first and second positions, it transitions the device from a locked state (preventing disassembly) to an unlocked state (allowing disassembly for refilling). This dynamic mechanism ensures children cannot accidentally disassemble it while maintaining ease of refilling for adults who know the operation sequence
Solution Approach 2:
The elastic member is pre-loaded to automatically hold the operating member in the first position (locked state) before any operation. This preliminary action ensures the device is always in a safe locked state by default, and only becomes disassemblable after the user deliberately performs the unlocking sequence (rotating the operating member to engage limiting portions, then moving axially)
2Object-affected harmful factors
If a locking mechanism with operating member is added, then the safety against accidental disassembly is improved, but the device complexity increases
Solution Approach 1:
The operating member serves multiple functions: it acts as both a rotational element (to engage/disengage limiting portions) and an axial movement element (to lock/unlock the connection). The elastic member simultaneously provides both the locking force and the return force. This multi-functionality reduces the need for separate components, thereby minimizing the increase in device complexity while achieving the safety goal
Solution Approach 2:
The operating member is sleeved on the second pipe, nesting it within the existing structure. The elastic member is disposed between the second pipe and the operating member, fitting within the annular space. This nested arrangement integrates the locking mechanism into the existing atomizer structure without adding significant external complexity or increasing the overall device size
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
The solution significantly increases the difficulty of disassembling the atomizer, thereby preventing accidental ingestion of the liquid medium by children, enhancing safety by ensuring the atomizer remains securely assembled.
Implementation Method 1
an elastic member disposed between the second pipe and the operating member to elastically hold the operating member in the second position
Implementation Method 2
when the operating member is in the first position, the operating member cooperates with the second pipe to transmit a torsional force applied to the operating member by the outside to the second pipe
