Electronic Cigarette Atomizer Sealing Mechanism for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarettes lack effective child protection mechanisms, as the liquid storage assembly does not automatically seal when detached, posing a safety hazard due to exposure of cigarette liquid.
Innovation Solution
A liquid storage assembly with a sealing member that automatically seals the liquid outlet opening when the atomizing assembly is separated, utilizing an elastic or magnetic mechanism to ensure the liquid storage chamber remains sealed, preventing accidental ingestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid storage assembly and atomizing assembly are detachably connected for ease of operation and maintenance, then the ease of operation is improved, but the liquid storage chamber fails to automatically seal when separated, creating safety hazards
Solution Approach 1:
The sealing member is pre-positioned to automatically seal the liquid storage chamber when the atomizing assembly is detached, eliminating the need for manual sealing operations and ensuring child protection is activated before any harmful exposure can occur
Solution Approach 2:
The sealing mechanism operates autonomously through elastic or magnetic forces, automatically sealing the liquid storage chamber upon separation of assemblies without requiring user intervention, thereby providing consistent safety protection
2Object-affected harmful factors
If a sealing mechanism is added to automatically seal the liquid storage chamber when detached, then the safety protection is improved, but the device complexity increases
Solution Approach 1:
The sealing member utilizes changes in elastic or magnetic parameters to achieve automatic sealing - the elastic member deforms under compression during assembly and restores to seal upon disassembly, while the magnetic member leverages magnetic field strength changes to provide sealing force, simplifying the mechanism by relying on inherent material properties rather than complex mechanical systems
Solution Approach 2:
The patent replaces traditional mechanical sealing mechanisms with elastic or magnetic field-based sealing, eliminating the need for complex mechanical linkages, springs, or actuators, thereby reducing device complexity while maintaining effective sealing functionality
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 effectively prevents children from contacting or ingesting the cigarette liquid by ensuring the liquid storage chamber is sealed when the atomizing assembly is detached, thereby enhancing safety protection.
Implementation Method 1
the sealing member is reset to the first state under the elastic force of the elastic member
Implementation Method 2
the sealing member is reset to the first state under the magnetic attraction of the magnetic member

AI summary
An atomizer includes a liquid storage assembly and an atomizing assembly. The liquid storage assembly includes a liquid storage tube internally provided with a liquid storage chamber, a liquid outlet opening communicating with the liquid storage chamber, and a sealing member movably received in the liquid storage chamber. The atomizing assembly includes an atomizing chamber and a pushing member. When the liquid storage assembly and the atomizing assembly are separated, the sealing member is in a first state in which the sealing member seals the liquid outlet opening. When the liquid storage assembly and the atomizing assembly are connected, the pushing member abuts against the sealing member to drive the sealing member to move to a second state in which the sealing member is separated from the liquid outlet opening.
