As the vacuuming continues, the external atmospheric pressure presses the vacuum hood against the workbench, and the vacuum hood and the workbench are gradually completely sealed by pressing the vacuum hood and the sealing ring at the edge of the workbench. In reality, during use, due to the repeated opening of the vacuum hood, the sealing ring at the bottom of the vacuum hood will gradually age and the sealing effect will gradually decrease, which will gradually prolong the time to reach the set vacuum negative pressure parameters, affecting the efficiency of vacuum packaging.
