Technical Field

[0001] The utility model relates to the technical field of air tightness detection equipment, in particular to an air tightness detection device for a windshield washer. Background Art

[0002] The windshield washer air tightness test device is a device used to test the air tightness or sealing of the automobile windshield washer under pressure. The main function of this device is to ensure that the windshield washer does not leak during use and maintains its normal working condition, thereby ensuring the safety of automobile driving.

[0003] Most existing windshield washer air tightness detection devices increase the pressure in the windshield washer and then determine the air tightness of the windshield washer based on the value of the pressure gauge. If the windshield washer only has a slight leak, it is necessary to observe the changes in the pressure gauge for a long time to determine whether the air tightness of the windshield washer is damaged. This detection method not only has a slow detection process, but also has high requirements on the sensitivity of the pressure gauge. If the sensitivity of the pressure gauge deteriorates, the detection work cannot be carried out normally. Therefore, it is necessary to develop a windshield washer air tightness detection device with fast detection speed and independent of the sensitivity of the pressure gauge. Utility Model Content
