[0028] It is worth noting that the circuits, electronic components and modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0029] The working principle of the sealing device for extending the shelf life of protein provided by the utility model is as follows:

[0030] When in use, first open the sealing cover, then put the protein product to be stored on the placement plate 2 from the take-out port, and close the sealing cover after putting it in. At this time, if there is still a lot of empty space inside the device, the dual-axis motor 7 can be started, and the dual-axis motor 7 will drive the two rotating shafts 8 to rotate. The two rotating shafts 8 will respectively drive the two first bevel gears 10 to rotate. The two first bevel gears 10 will drive the two screws 9 to rotate through the two second bevel gears 11. The two screws 9 will drive the two sliders 12 to slide vertically on the inner walls of the two chutes, so that the two sliders 12 drive the second box body 3 to move vertically. The second box body 3 moves downward, and the device will become smaller. The second box body 3 moves upward, and the device will become larger. In this way, the size of the device can be adjusted according to the storage amount of the protein product, which can reduce the space occupied.

[0031] Then start the vacuum pump 5, which will exhaust the gas inside the first box 1 and the second box 3 through the exhaust pipe 6. After the gas is exhausted, the protein product can be stored in a vacuum environment, which can improve the preservation effect and help to increase the shelf life of the protein product. Start the semiconductor refrigeration piece 4, and the refrigeration surface of the semiconductor refrigeration piece 4 will cool the gas inside the first box 1 and the second box 3, so that the device can store the protein product at a low temperature. When the temperature sensor detects that the internal temperature is lower than the set value of the controller, the controller will automatically turn off the semiconductor refrigeration piece 4. The controller will not start the semiconductor refrigeration piece 4 again until the temperature is higher than the set value of the controller. This cycle is repeated continuously, which can achieve the benefit of energy saving.

[0032] Each time the semiconductor cooling plate 4 is activated, the fan 14 is also activated, causing the fan 14 to cool the heat dissipation surface of the semiconductor cooling plate 4 by blowing air. When a person needs to move the device, the multiple electric push rods 17 are activated, and the multiple electric push rods 17 will move the multiple universal wheels 18 out of the multiple bottom shells 15, so that the multiple universal wheels 18 are close to the ground. Then, the person only needs to pull the handle to move the device. When the handle length needs to be adjusted, the screw rod 20 is rotated. Since the screw rod 20 is threadedly connected to the sleeve 19, it can be moved in the sleeve 19. The movement of the screw rod 20 can adjust the length of the handle. The operation is relatively convenient.

[0033] Compared with related technologies, the sealing device for extending the shelf life of protein provided by the present invention has the following beneficial effects:

[0034] The utility model provides a sealing device that can extend the shelf life of protein. The sealing performance between the first box body 1 and the second box body 3 can be ensured by the sealing ring 13. The height of the second box body 3 can be conveniently adjusted by the lifting mechanism. When the second box body 3 moves downward, the device will become smaller. When the second box body 3 moves upward, the device will become larger. Thus, the size of the device can be adjusted according to the storage amount of the protein product, which can reduce the space occupied. The gas inside the first box body 1 and the second box body 3 can be discharged by the vacuum pump 5, the exhaust pipe 6 and the one-way valve. After the gas is exhausted, the protein product can be kept in a vacuum state. Storing in a low-temperature environment can improve the preservation effect and is beneficial to increasing the shelf life of protein products.
