In the pressure holding period of the test, when the pressure detected by the first detecting member 430 and the second detecting member 530 does not change, the device under test 20 is indicated as a qualified product by the indicating member 150.

In one embodiment, the water and air joint inspection device 10 further includes two start buttons 160, the two start buttons 160 are electrically connected in series, and the start buttons 160 are disposed on the rack 100. In the process of start detection, two start buttons 160 need to be pressed simultaneously to realize two-hand start, thereby avoiding the clamping mechanism from clamping hands. Wherein two start buttons 160 are provided on the rack 100. In other embodiments, there may be one start button 160.

In one embodiment, the water joint inspection device 10 further includes a stop button 170, and the stop button 170 is disposed on the rack 100.

When the water and air joint inspection device 10 is used, the device 20 to be tested is disposed in the first holding space or the second holding space, and the two start buttons 160 are manually pressed.

When water tightness detection is performed, the first clamping assembly 200 clamps the device to be detected 20, the water inlet valve 410 is opened, the drain valve 420 is closed, water is filled into the device to be detected 20 through the booster pump 440, the booster pump 440 stops working after the water pressure reaches a detection target value, and the water inlet valve 410 is closed to enter a water tightness detection pressure maintaining stage. If the pressure holding is qualified, the indicator 150 indicates that the water tightness of the device under test 20 is detected as a qualified product. If the pressure holding is not qualified, the warning device 140 displays that the water tightness of the device under test 20 is detected as a non-qualified product.

When the air tightness detection is performed, the second clamping assembly 300 clamps the device under test 20, opens the air inlet valve 510, closes the air outlet valve 520, and fills the compressed air into the device under test 20 through the air inlet 310. After the air pressure reaches the detection target value, the inflation is stopped, and the air inlet valve 510 is closed to enter the air tightness detection pressure maintaining stage. The pusher 110 further drives the mounting member 130 to move, so as to drive the dut 20 to move into the water tank 120. If the pressure maintaining is qualified, the indicator 150 indicates that the airtightness of the device under test 20 is detected as a qualified product. If the pressure maintaining is not qualified, the warning device 140 displays that the air tightness of the device 20 is detected as an unqualified product, and meanwhile, bubbles appear in the water tank 120, thereby further facilitating the judgment of the air leakage position of the device 20.

The water-air joint inspection device 10 can also perform air tightness inspection first and then water tightness inspection, or perform only air tightness inspection or only water tightness inspection according to the inspection requirements of the device to be inspected 20. In the process of performing water sealing and air sealing detection on the device to be detected 20, the water and air joint inspection device 10 does not need to replace different equipment for the device to be detected 20, so that the detection efficiency is effectively improved.
