Explosion-Proof Battery Box Valve With Manual Humidity Venting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-humidity environments, the automatic switch of existing explosion-proof valves in battery boxes allows excessive water vapor to enter, affecting the batteries or battery modules.
Innovation Solution
An explosion-proof valve with a manually adjustable breathing mechanism and sealing gaskets to control communication between the inside and outside of the box, preventing water vapor entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an automatic switch is provided in the explosion-proof valve to adjust pressure difference, then the pressure balance between inside and outside of the box is improved, but water vapor enters the box in high-humidity environments affecting the batteries
Solution Approach 1:
The patent extracts the automatic switching function from the explosion-proof valve by providing a separate breathing mechanism that can be manually controlled. The breathing mechanism includes a breathing switch that can be opened or closed independently, allowing the pressure balance function to be maintained while preventing unwanted water vapor ingress through manual control based on external environment conditions.
Solution Approach 2:
The patent introduces a manually adjustable breathing mechanism that transitions from a fixed automatic state to a dynamic controllable state. The breathing switch can be dynamically opened or closed by the user based on external humidity conditions, allowing the system to adapt its breathing state according to environmental conditions rather than operating automatically in all conditions.
2Stress or pressure
If the breathing switch is opened to communicate inside and outside of the box, then pressure difference is relieved, but water vapor enters the box
Solution Approach 1:
The patent enables the user to manually control the breathing switch based on their knowledge of external environmental conditions. The user serves themselves by making informed decisions about when to open or close the breathing mechanism, preventing water vapor ingress while still allowing pressure relief when appropriate based on external conditions.
3Object-affected harmful factors
If the breathing mechanism is always closed to prevent water vapor entry, then protection against humidity is improved, but pressure difference cannot be adjusted
Solution Approach 1:
The patent introduces a manually adjustable breathing mechanism that transitions from a fixed automatic state to a dynamic controllable state. The breathing switch can be dynamically opened or closed by the user based on external humidity conditions, allowing the system to adapt its breathing state according to environmental conditions rather than operating automatically in all conditions.

AI summary
An explosion-proof valve and a box are provided in the application. The explosion-proof valve is configured for installing in the box, and includes a valve body including a breathing passage, a press cover and a breathing mechanism. The valve body is connected to the valve body, and a gap is between the press cover and the valve body. The breathing mechanism is movably connected to the press cover, and a breathing switch is formed between the breathing mechanism and the valve body. When the breathing mechanism abuts against the valve body, the breathing switch is closed, and an inside of the box is not in communication with an outside of the box. When the breathing mechanism is separated from the valve body, the breathing switch is opened, and the inside of the box is communicated with the outside of the box.
