The operator fixes the tire at the rubber disc 3, and then starts the starting switch 6 at the air valve 5. At this time, the air valve 5 starts to transport air into the air pipe 9, and the air enters the No. 1 air guide port 18 through the air pipe 9, and then enters the air bin 14 and pumps the air into the rubber airbag through the air vent 11 in the air bin 14. At this time, the slider 15 starts to move downward along the guide rail 19 and brings the tire into the water. At this time, the air pressure between the tire and the rubber disc 3 increases as the rubber airbag 10 gradually becomes larger. At this time, the operator can judge whether the sealing of the tire repair point is qualified by observing whether bubbles are generated on the water surface.

[0020] The bottom side of the stainless steel water pool 2 is provided with a perforation, in which a water outlet pipe 7 is arranged, and the other end of the water outlet pipe 7 is provided with a cover 8. When the detection is completed or the water pool needs to be cleaned, the operator opens the cover 8 on one side of the water outlet pipe 7 to drain the water in the stainless steel water pool 2.

[0021] Working principle: when testing the sealing of the tire repair point, the operator opens the faucet before the test to let water flow into the stainless steel pool 2 through the water inlet pipe 4. When the water level reaches the requirement, close the faucet and start the test. The operator fixes the tire on the rubber disc 3 and then starts the start switch 6 at the air valve 5. At this time, the air valve 5 starts to transport air into the air pipe 9. The air enters the No. 1 air guide port 18 through the air pipe 9, and then enters the air warehouse 14 and pumps the air into the rubber airbag through the vent 11 in the air warehouse 14. At this time, the slider 15 starts to move downward along the guide rail 19 and brings the tire into the water. At this time, the air pressure between the tire and the rubber disc 3 increases through the gradual expansion of the rubber airbag 10. At this time, the operator can judge whether the sealing of the tire repair point is qualified by observing whether bubbles are generated on the water surface; when the test is completed or the pool needs to be cleaned, the operator opens the cover 8 on one side of the water outlet pipe 7 to drain the water in the stainless steel pool 2.
