Title:
HANDHELD LEAKAGE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2022/246908
Kind Code:
A1
Abstract:
A handheld leakage detector, relating to the field of detection, comprising: a detection body (100) having a detection surface (110); a heating assembly (200) configured to provide a heat source for the detection surface (110); and a temperature acquisition assembly (300) comprising a plurality of first detection portions (310) located on the detection surface (110), the first detection portions (310) being used for acquiring temperature information of air at the side of the detection body (100) facing the detection surface (110). When the detection body (100) is placed at a possible leakage position, if there is a leakage, the leakage position generates an airflow, and the airflow carries away the air heat on the side of the detection surface (110), so that the air temperature is reduced, the air temperature acquired by the temperature acquisition assembly (300) changes in real time, and whether there is a leakage is determined according to the temperature information, acquired by the temperature acquisition assembly, of the air at the side of the detection body (100) facing the detection surface (110).
