However, existing refrigerators still have certain disadvantages: they cannot integrate vacuum sealing equipment. If you want to achieve the vacuum preservation function, the cost is high and the space occupied is large; the existing direct storage method of refrigerators makes the stored food easy to lose moisture, become stale, and easily tainted with flavors and infected with bacteria; the vacuum preservation function in the cabinet occupies the volume of the refrigerator, reducing the food storage space.

When the screw rod rotates, the discharge plate moves horizontally on the surface of the screw rod, and the material is removed from the top of the discharge plate into the material discharge chute; an electric cylinder is bolted to the left side of the discharge plate, and a push plate is bolted to the right side of the electric cylinder through the discharge plate, so that the electric cylinder drives the push plate to move to the right, and pushes the material from the top of the discharge plate to the inside of the rectangular frame.

[0006] Preferably, a first servo motor is bolted to the left side of the material discharge chute, and the left side of the screw rod is bolted to the output end of the first servo motor, so that the first servo motor serves as a driving source and drives the screw rod to rotate in the material discharge chute.

[0007] Preferably, a second servo motor is bolted to the front of the rectangular frame in a circular arrangement, and the output end of the second servo motor is bolted to the front of the rotating rod, so that the second servo motor serves as a driving source to drive the rotating rod to rotate outside the rectangular frame and control the rotation direction of the rotating rod.

[0008] Preferably, a third servo motor is bolted to the front of the cabinet, and the front of the rotating shaft passes through the cabinet and is bolted to the output end of the third servo motor, so that the third servo motor serves as a driving source to drive the rotating shaft to rotate rapidly in the cabinet.

[0012] This technical solution successfully combines the innovative design of the vacuum sealing device with an integrated design and multi-functional integration through components such as a freezer, a cooling bin, a mounting rack, and a sealing cylinder. Food is placed in a vacuum fresh-keeping bag, which is then placed in the freezer after vacuum sealing. The food can be kept fresh for a long time. The freezer and the vacuum sealing device have two functions and can be used for multiple purposes. They can be used separately without affecting each other.

[0013] This technical solution uses components such as a rotating shaft, a rectangular frame, a rotating rod, a closing plate, and an insertion slot to facilitate users to take out and use materials, thereby avoiding the situation in traditional refrigerators where materials are at the bottom of the cabinet and the need to search from top to bottom for the required materials, thereby improving the practicality of the refrigerator.
