Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic atomizing devices face safety issues due to potential battery explosions under extreme conditions, which can cause injuries as harmful gases may enter the atomizer and be inhaled by users.
Innovation Solution
A power supply assembly with a sealing member that deforms under pressure differences above a threshold, forming an interference fit with the electrode post and through hole to prevent gas leakage, and includes a protective cover and exhaust hole to manage high-pressure gas safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional power supply assembly is used without special sealing structures, then the device structure is simple, but harmful gases can leak through clearances and be inhaled by users when the battery explodes
Solution Approach 1:
The sealing member is made of elastic material that can deform under pressure to seal the clearance between the electrode post and the sealing member, preventing harmful gas leakage while maintaining structural simplicity
Solution Approach 2:
The sealing member utilizes pressure-dependent deformation to change its sealing characteristics dynamically - remaining open during normal operation but sealing automatically when pressure difference exceeds the threshold during battery explosion
2Reliability
If the sealing member is always in contact with the first abutting surface, then the sealing is reliable, but the assembly process becomes complex and the structure is more complicated
Solution Approach 1:
The sealing member is pre-configured with the through hole and electrode post positioning features, allowing it to be installed in a single step where it automatically assumes the correct position and sealing contact with the first abutting surface
Solution Approach 2:
The sealing member is designed as a separate, modular component with integrated features (through hole, electrode post accommodation, and abutting surface contact), enabling independent installation and simplifying the overall assembly process
3Object-affected harmful factors
If the sealing member deforms to seal the clearance under pressure difference, then harmful gas leakage is prevented, but the sealing member may be damaged under extreme pressure
Solution Approach 1:
The elastic sealing member is designed with sufficient deformation capacity to absorb extreme pressure during battery explosion without permanent damage, allowing it to return to its original state after the pressure event
Solution Approach 2:
The sealing member utilizes pressure-dependent deformation to change its sealing characteristics dynamically - remaining open during normal operation but sealing automatically when pressure difference exceeds the threshold during battery explosion

Function Achieved in This Case
The solution effectively seals the clearance between the electrode post and sealing member, preventing harmful gases from entering the atomizer and improving user safety by managing high-pressure gas safely, thus enhancing the safety of electronic atomizing devices.
Implementation Method 1
When a difference between a pressure of one end of the sealing member adjacent to the battery and a pressure of the other end of the sealing member away from the battery is greater than a threshold pressure, the sealing member presses against the first abutting surface, and the sealing member is deformed to seal a clearance between the electrode post and the sealing member in the through hole
Implementation Method 2
the sealing member is deformed to seal a clearance between the electrode post and the sealing member
Implementation Method 3
when a pressure difference acting on the sealing member is greater than the threshold pressure, the electrode post and the through hole are in an interference fit

AI summary
The present disclosure relates to a power supply assembly and an electronic atomizing device. The power supply assembly includes a battery, an electrode post electrically connected to the battery, a sealing member, and a support. The battery supplies power to the atomizer through the electrode post. The sealing member is provided with a through hole, and the electrode post extends through the through hole. The support has a first abutting surface. The battery and the sealing member are disposed in the support. When a difference between a pressure of one end of the sealing member adjacent to the battery and a pressure of the other end of the sealing member away from the battery is greater than a threshold pressure, the sealing member presses against the first abutting surface, and is deformed to seal a clearance between the electrode post and the sealing member in the through hole.
