[0044] The use method and principle of the utility model:
[0045] When an airtightness test is required on product 100, product 100 is first placed on the limiting block assembly 9 of the support assembly 8.

At this time, spring 806 is compressed first. Then, the sealing assembly and limiting rod 604 press down on product 100 to limit and fix it. The spring on the sealing assembly is also compressed. The air pump supplies air to the vent column 602 in the sealing assembly to increase the air pressure inside product 100. Then, the piston rod of cylinder 503 continues to extend, driving the support assembly 8 and product 100 into the water tank. At this time, the air pressure inside product 100 has risen to the required test value, and the airtightness test begins. After product 100 enters the water tank, the test state will be maintained for 30 seconds. After the airtightness test is completed, the piston rod of cylinder 503 will retract, driving the lifting mechanism 5 and the sealing assembly to rise. The rebound force of spring 806 will also drive the support assembly 8 and product 100 to float to the surface together.
