At this time, the lower end of the driven rod 55 abuts against the movable plug 56 and makes the movable plug 56 seal the first exhaust hole. At this time, the air in the vacuum chamber can be pre-extracted first. When evacuating the fruit tray, rotate the driving rod 54 so that the driving block 541 at the lower end of the driving rod 54 is placed at the bottom of the driven groove 551, so that the driven rod 55 loses the mortgaging effect on the movable plug 53. Under the action of atmospheric pressure, the movable plug 53 will open, and the air in the fruit tray will enter the vacuum chamber, so that the air in the fruit tray can be quickly extracted, with high efficiency and convenient use. When performing vacuum storage, buckle the cover body 2 on the disc body 1 and press the pressing cover 52. The pressing cover 52 drives the movable cylinder 51 to move downward. The movable cylinder 51 can drive the driving rod 54 to move downward, and the driving rod 54 drives the driven rod 55 to move downward. The driven rod 55 moves downward to squeeze the movable plug 53, so that the first exhaust hole can be sealed. By moving the movable cylinder 51 downward, the volume of the vacuum chamber can be changed, so that the air in the vacuum chamber is squeezed out from the second exhaust hole. After removing the external force, the movable cylinder 51 will reset. Under the action of atmospheric pressure, the movable plug 53 opens, and the air in the fruit tray will enter the vacuum chamber. A one-way flow exhaust channel is formed through the movable plug 53, the vacuum chamber and the exhaust plug 56, so that the air in the fruit tray can be extracted, and a vacuum environment is formed in the fruit tray, which is beneficial to the long-term storage of fruits. After evacuating, rotate the movable cylinder 51, so that the lower end of the driven rod 55 abuts against the movable plug 56 and makes the movable plug 56 seal the first exhaust hole, so that when the fruit tray is opened, the vacuum environment in the vacuum chamber can also be ensured, which is convenient for the next use.
