[0035] The working principle and use process of the utility model are as follows: the user first installs the control box 81, and installs each mounting block 91 on the top of the operating table 2 according to the size of the control box 81, and then places the control box 81 between the mounting blocks 91. When the control box 81 is pressed downward, the surface of the control box 81 will squeeze the card block 92, so that the card block 92 is deformed toward the outside of the mounting block 91. When the card slot 93 moves to the position of the card block 92, the card block 92 will reset, and the top of the card block 92 surface is engaged with the card slot 93 to prevent the control box 81 from moving up and down. When the user needs to remove the control box 81, he only needs to bend the card block 92 toward the outside of the mounting block 91 so that the card slot 93 is no longer connected to the card block 92, which is convenient for the user to install or remove the control box 81, and use the control box 81 to start the electric cylinder 83. When the electric cylinder 83 When the output end of the vacuum pump 6 moves up and down, it will drive the connecting rod 84 to move up and down. When the connecting rod 84 moves up and down, the heating plate 4 will move up and down. When the heating plate 4 moves upward, the user puts the packaging bag that needs to be vacuum-sealed on the bottom of the heating plate 4, and the heating plate 4 presses and heats it to make the seal melt together, and then uses the mounting plate 82 to facilitate placing the electric cylinder 83 on the top of the connecting rod 84. During the long-term use of the vacuum pump 6, a lot of dust will enter the interior of the vacuum pump 6 at the input end of the vacuum pump 6. The filter 11 is used to block most of the dust from entering the interior of the vacuum pump 6, so that the vacuum pump 6 can be used for a longer time. When the user installs the filter 11, the connecting block 13 is aligned with the mounting groove 12 to connect the filter 11 to the output end of the vacuum pump 6, thereby achieving the effect of easy cleaning.

[0036] In summary, the fruit and vegetable refrigerated vacuum packaging device is provided with an air extractor 6 and a nozzle 7, and uses the air extractor 6 to collect external air, and the nozzle 7 sprays the air, and then uses the wind blown by the nozzle 7 to blow the dust and foreign matter on the surface of the operating table 2 out of the operating table 2, so that it is convenient for the user to clean the operating table 2, and solves the problem that there may be foreign matter at the heating strip of the vacuum packaging, which affects the sealing of the vacuum packaging of fruits and vegetables, and easily causes air leakage during the subsequent transportation of fruits and vegetables, so that the fruits and vegetables cannot be preserved for a long time, thereby affecting the packaging quality of the vacuum packaging machine.
