Description

Technical Field

[0001] The utility model belongs to the technical field of gas leakage detection equipment, and particularly relates to an anti-interference type perfluoroisobutyronitrile gas leakage detection device. Background Art

[0002] A perfluoroisobutyronitrile gas leak detection device is a device used to detect the leakage of perfluoroisobutyronitrile gas (also known as C4F8). Perfluoroisobutyronitrile is a gas widely used in the semiconductor manufacturing process for cleaning surfaces and filling cavities. However, perfluoroisobutyronitrile is highly toxic and environmentally hazardous, so its leakage needs to be monitored to ensure the safety of the working environment. A perfluoroisobutyronitrile gas leak detection device usually includes components such as sensors, alarms, and displays. The sensor can detect the concentration of perfluoroisobutyronitrile gas in the air. Once a leak is detected, the alarm will sound an alarm to remind the user to take appropriate emergency measures. At the same time, the display can show the numerical value of the gas concentration, allowing the user to monitor the extent of the gas leakage in real time.

[0003] Some existing detection devices may be relatively large, which limits their use in small spaces. When operating in a small space, the device may face limited space, resulting in inflexible movement and deployment. Due to the dimensional limitations of the small space, the detection device may not be able to provide sufficiently detailed leak detection sensitivity, which may result in the failure to timely detect low-concentration perfluoroisobutyronitrile gas leaks in the small space, which in turn interferes with the final results and makes the detection results inaccurate. Therefore, we hope to design a welding device with a new structure to solve this problem. Utility Model Content
