[0039] like Figures 1 to 6 The figure shows the waterway airtightness testing machine of the present invention, which is used to automatically seal a product's waterway and perform airtightness testing. It specifically comprises a frame 1, a conveyor assembly 2, a lifting assembly 3, and a testing assembly 4. The conveyor assembly 2 drives the product to be tested beneath the lifting assembly 3, whereupon the testing assembly 4 is mounted. The lifting assembly 3 then drives the testing assembly 4 downward for airtightness testing. The testing assembly 4 and the lifting assembly 3 are detachably connected, allowing for quick removal and replacement of the testing assembly 4 to accommodate products with varying numbers of waterway openings.

[0040] See also Figure 3As shown, the conveying assembly 2 includes a conveyor line 21 provided on the frame 1, and a product fixture 22 movably connected to the inner side of the conveyor line 21.
