Solution Overview
Problem
Conventional electronic atomizing devices face safety concerns due to potential battery explosions under extreme conditions, as existing safety measures fail to effectively prevent the inhalation of high-pressure gases and harmful substances by users.
Innovation Solution
Incorporating a cushion plug mechanism within the power supply assembly that automatically closes the functional channel when a threshold air pressure difference is exceeded, preventing harmful substances from entering the air inhaling channel during battery explosions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed cavity structure is used to contain the battery, then safety against external factors is improved, but harmful gases generated by the battery cannot be released and may cause explosion
Solution Approach 1:
The bottom cover is designed with a pre-formed groove structure that creates an emergency exhaust pathway before any explosion occurs. This preliminary structural arrangement ensures that when gas accumulates in the sealed cavity, it can automatically escape through the groove without requiring additional active components or user intervention.
Solution Approach 2:
The invention converts the harmful effect of gas accumulation (which could cause explosion) into a beneficial pressure-driven automatic exhaust mechanism. The gas pressure that would otherwise be dangerous is utilized to force the bottom cover away from the main body, opening the emergency exhaust groove and safely releasing the accumulated gas.
2Object-generated harmful factors
If an emergency exhaust groove is designed into the bottom cover, then gas release capability is improved, but the sealing performance between bottom cover and main body deteriorates
Solution Approach 1:
The bottom cover is designed to dynamically adjust its position relative to the main body based on internal pressure conditions. Under normal operation, the bottom cover maintains a sealed position against the main body. When gas pressure exceeds a threshold, the bottom cover automatically moves away to open the exhaust groove, providing a dynamic seal that adapts to operational conditions.
Solution Approach 2:
The groove structure is pre-designed in the bottom cover at a location that allows it to function as both a sealing surface and an emergency exhaust pathway. This preliminary structural arrangement enables the bottom cover to maintain sealing under normal conditions while providing a predetermined escape route for excessive gas pressure.
3Object-generated harmful factors
If the bottom cover is designed to move away from the main body for gas release, then explosion-proof capability is improved, but structural stability deteriorates
Solution Approach 1:
The connection between the bottom cover and main body is designed to be dynamically adjustable rather than rigidly fixed. The bottom cover can maintain a stable connected state during normal operation, but can automatically separate when gas pressure exceeds safety thresholds. This dynamic connection provides both structural stability and explosion-proof capability.
Solution Approach 2:
The gas pressure that threatens structural stability is converted into a beneficial force that triggers the safety release mechanism. The same pressure that could cause explosion is utilized to automatically open the exhaust groove by separating the bottom cover from the main body, transforming a harmful effect into a protective action.

Enhances the safety performance of electronic atomizing devices by blocking high-pressure gases and harmful substances from entering the inhalation pathway during battery explosions, thereby protecting users from potential harm.
Implementation Method 1
When a difference between air pressure in the receiving cavity and air pressure in the air inhaling channel exceeds a threshold pressure, the cushion plug moves from a first station to a second station

AI summary
An electronic atomizing device (10) includes an atomizer (30, 700) provided with an air inhaling channel (31, 601) therein for inhalation of aerosol, a power supply assembly (20, 900) comprising a battery (200, 21) supplying power to the atomizer (30, 700) and provided with a receiving cavity (110, 911), a functional channel (740) providing communication between the air inhaling channel (31, 601) and the receiving cavity (110,911), and a cushion plug (300, 800) disposed in the functional channel (740). When the difference between the air pressure in the receiving cavity (110, 911) and the air pressure in the air inhaling channel (31, 601) exceeds the threshold pressure, the functional channel (740) is in a closed state. Therefore high pressure gases and harmful substances generated if the battery explodes can not pass through the functional channel into the air inhaling channel to be inhaled by the user.
