Atomizer Latching Mechanism for Child-Safe Liquid Refill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic cigarette atomizers with top or side liquid injection modes are inconvenient for users and lack child safety features, as children can easily access and open the liquid intake holes, posing a safety hazard.
Innovation Solution
An atomizer design featuring a liquid storage chamber with a unique upper cover assembly and connecting member that includes a rotatable shaft, limiting shaft, and latching mechanism, which requires a translational push and rotational movement to open the liquid intake hole, making it difficult for children to access and improving security through a 'L' shaped sliding groove and latching system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If top liquid injection or side surface liquid injection is adopted, then cleaning convenience is improved, but operation convenience deteriorates due to frequent opening and closing
Solution Approach 1:
The atomizer pre-opens the liquid intake hole during assembly or before use, eliminating the need for frequent opening and closing operations. The liquid intake hole is manufactured in an open state, allowing users to directly add liquid without manual opening actions, thus resolving the contradiction between cleaning convenience and operation convenience.
2Ease of operation
If traditional liquid injection modes are used, then liquid access is simplified, but child safety deteriorates as children can easily open the atomizer
Solution Approach 1:
The atomizer is divided into separable components including an upper cover assembly and a body assembly. The liquid intake hole is selectively openable through a latching mechanism that requires deliberate action to open, preventing children from easily accessing the liquid while maintaining convenient liquid access for adult users.
Solution Approach 2:
The atomizer employs a dynamic latching mechanism with a latching clip and latching groove that can transition between locked and unlocked states. This dynamic system allows controlled access to the liquid intake hole, providing safety against unintended opening by children while enabling convenient liquid refilling by users.
3Ease of operation
If bottom liquid injection is adopted, then operation simplicity is improved, but sealing performance deteriorates
Solution Approach 1:
The atomizer introduces a latching clip as an intermediary component between the upper cover assembly and body assembly. This latching mechanism serves as a mediator that maintains reliable sealing by engaging with the latching groove, preventing unintended opening while allowing deliberate liquid refilling operations.

AI summary
An atomizer for an electronic cigarette includes an upper cover assembly, a base assembly, and an atomizer head. The upper cover assembly includes an inner lining member defining a positioning hole and a first sliding groove, the first sliding groove includes a translational groove and a rotation groove in communication with the translational groove, the position hole is parallel to the translational groove, and a connecting member defines a first liquid intake hole in communication with the liquid storage chamber. The atomizer requires a translational push is needed prior to opening the liquid intake hole by a side sliding so as to improve safety.
