[0012] The advantages of this application are as follows:

[0013] The blister to be tested is placed in a test liquid with a suitable temperature, and the vacuum pump is turned on to extract the air in the test cavity through the vacuum pipe, so that the test cavity reaches a negative pressure state and the blister is tested. Hot water is used as the test liquid, and the test cavity reaches a negative pressure state. As the air pressure decreases, the hot water will boil, and the partition plate can block the splashing test liquid to prevent the splashing test liquid from entering the vacuum pipe, thereby protecting the vacuum pump. A partition is provided between the partition plate and the side wall of the test cavity, and the partition plate divides the test cavity into a connected upper part and a lower part. The caliber of the connection between the upper and lower parts is small, and the partition plate controls the direction of the airflow in the test cavity.
