The invention relates to the technical field of disinfection cabinet detection and in particular to a disinfection cabinet airtightness detection system which is mainly composed of a control module, adigital display module, an airtightness testing module and a leakage position detecting module. In the airtightness testing module, a high-pressure gas pump transfers clean compressed air to a disinfection cabinet via an air pipe. A flow controller and a solenoid valve are installed on the air pipe. The pressure test tube of a digital pressure sensor is located in the disinfection cabinet. The control module determines whether the disinfection cabinet leaks according to a pressure change of the compressed air in the disinfection cabinet. Leakage position detection mainly relies on the leakageposition detecting module. A robot arm controls a precision wind speed detector to run along the four sides of a cabinet door to test the wind speed in order to find a leak point. The disinfection cabinet airtightness detection system is fast in detection speed, can achieve full inspection on the domestic disinfection cabinet in cooperation with an assembly line, uses the clean air as a detectionmedium so as not to cause any harm to the human body.
Description
technical field [0001] The invention relates to the technical field of disinfection cabinet detection, in particular to a detection system for the airtightness of a disinfection cabinet. Background technique [0002] Most household disinfection cabinets are sterilized by ozone. Since high concentrations of ozone can strongly stimulate the human respiratory tract, cause human neurotoxicity, and damage the immune function of the human body, the household disinfection cabinet requires good sealing performance. [0003] With the popularization of automated production lines, household disinfection cabinets are automatically produced and assembled on assembly lines, and the production speed can reach one per minute. However, the detection time of the existing ozone detectors is about 30 minutes per set, so it is only possible to conduct a sampling inspection of the household disinfection cabinets on the assembly line, and it is impossible to do a full inspection; moreover, the ...
