Description

Technical Field

[0001] This utility model relates to the field of filter leak detection technology, specifically a filter leak detection device. Background Technology

[0002] A filter leak detection device is used to detect whether a filter can effectively perform its filtering function without leaking. The existing detection method is that one operator introduces gas containing particles into the filter at one end, while another operator scans at the other end to complete the leak detection test. When scanning column by column / row, the scanning areas of adjacent columns / rows need to overlap to avoid missing detections.

[0003] However, in the existing technology, the length of the existing leak detection device cannot be flexibly adjusted, and the device itself cannot control the scanning interval. Operators need to control the scanning interval of adjacent columns / rows by themselves. Manual control of the interval is prone to result in the interval being too small or too large, which leads to waste of manpower or missed detection.

[0004] Chinese patent document CN117740259A discloses a leak detection method for a helium mass spectrometer leak detection system with cyclic leak detection. The system cyclically adds and removes bottles to achieve continuous operation, improving the speed and accuracy of leak detection and reducing the cost of leak detection. However, it does not disclose how to solve the problem in the field of filter leak detection: the existing leak detection devices cannot flexibly adjust the length and cannot control the scanning interval, which can easily lead to wasted manpower or missed detections when operators scan.

[0005] In summary, the problem to be solved is how to design a filter leak detection device that allows for flexible length adjustment for easy operation and control of the scanning interval to prevent wasted manpower or missed detections during scanning. Utility Model Content
