Vaporizer Power Supply Assembly With Isolated Airflow Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaporization devices face safety risks due to power supply explosions, which can direct impact forces towards the user's face or mouth, and fail to meet UL8139 security tests.
Innovation Solution
A power supply assembly with a holder isolating the power supply from the vaporization component, featuring an airflow sensing apparatus and airflow channels, ensuring airflow generated during an explosion is directed away from the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply is directly mounted in the power supply assembly without isolation, then the device structure is simple, but the power supply explosion can directly impact the user's face or mouth causing safety risks
Solution Approach 1:
The power supply assembly is segmented into distinct functional zones using the holder as a partition. The holder divides the internal space to separate the power supply from the vaporization component and user-facing areas, creating isolated compartments that prevent explosion impact from reaching the user while maintaining structural organization.
Solution Approach 2:
The holder acts as an intermediary barrier between the power supply and the user-facing components. This intermediate structure absorbs and redirects explosion forces away from the user's face or mouth, serving as a protective mediator that maintains both safety and functional integration.
2Object-affected harmful factors
If the power supply faces the nozzle direction, then the device structure is simplified, but the explosion impact force directs powders, electrode pins, and tiny parts toward the user's mouth or face increasing danger
Solution Approach 1:
The holder creates an asymmetric internal arrangement within the power supply assembly, positioning the power supply at an angle or orientation that is not directly facing the nozzle. This asymmetric configuration ensures that explosion forces are directed away from the user's face or mouth rather than along the nozzle axis, reducing the harmful impact direction.
3Reliability
If the airflow channel and start airway are not isolated from the power supply, then the device structure is simpler, but the explosion can affect airflow paths and contaminate the vaporization system
Solution Approach 1:
The holder segments the internal airflow paths from the power supply compartment, creating separate airflow channels that do not directly communicate with the power supply area. This segmentation prevents explosion contaminants from entering the vaporization airflow paths while maintaining distinct functional zones for power and vaporization systems.
