The control unit 3 is used to control the operation of each component, wherein the limit device 6 is used to output signals to the control unit 3, and the control unit 3 respectively gives control signals to the heat sealing mechanism 4, the driving assembly and the vacuum pump assembly. When the trigger part 7 of the lifting movable part 5 cooperates with the limit device 6, and then the control unit 3 receives the start signal of the limit device 6, then the control unit 3 will work through the vacuum pump assembly and the exhaust air pipe assembly, which is conducive to realizing automatic control and operation, and is more conducive to realizing automatic adjustment of the vacuum chamber assembly, which can better meet the use needs of modern users.

[0029] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the limit device 6 includes a mounting seat 61 arranged inside the base 1, a limit switch 62 is arranged on the mounting seat 61, and the limit switch 62 is connected to the control unit 3. The side wall of the vacuum chamber assembly is provided with a limit hole 63 for the trigger part 7 to move up and down. The lifting movable part 5 is provided with a trigger part 7, and the trigger part 7 moves up and down with the lifting movable part 5. The trigger part 7 moves up and down in the limit hole 63, and when the trigger part 7 moves downward, it triggers the limit switch 62. At this time, the limit switch 62 is connected to the control unit 3, which greatly improves the automation level and is more conducive to meeting the user's use needs. It is worth noting that the circuit board used by the control unit 3 is reasonably arranged, simple in structure, and easy to implement. It is worth noting that the trigger part 7 and the lifting movable part 5 are integrally formed, or the trigger part 7 is arranged on a side surface of the lifting movable part 5 through a fixing part. It can be seen that this type is diverse and has a large selection space. It is also worth noting that the fixing part is a screw or a bolt, etc., which is easy to implement. In this embodiment, the trigger part 7 is a protrusion integrally formed with the lifting movable part 5. The protrusion moves up and down with the lifting movable part 5. The protrusion moves up and down in the limit hole 63. When the protrusion moves downward, it triggers the limit switch 62. At this time, the limit switch 62 is connected to the vacuum pump assembly for operation.

[0030] Embodiment 3: It can be explained on the basis of embodiment 2, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the driving assembly includes a cylinder 1 81, a cylinder 2 82, a vacuum pump 1 83 and a vacuum pump 2 84 arranged on the base 1, the cylinder 1 81 and the cylinder 2 82 are respectively located on both sides of the base 1, the vacuum pump 1 83 and the vacuum pump 2 84 are respectively located on both sides of the base 1, and a solenoid valve 85 is arranged on the base 1, the solenoid valve 85 is respectively connected to the cylinder 1 81, the cylinder 2 82 and the vacuum pump 1 83, the solenoid valve 85 is connected to the control unit 3, the limit switch 62 is connected to the control unit 3, and the vacuum pump 1 83 is connected to the external external pumping pipe through the external pumping connecting pipe. When the external external pumping tube is not connected to the external pumping connecting tube and the vacuum bag placed between the drain trough and the vacuum chamber assembly is evacuated (the vacuum chamber assembly is in contact with the drain trough to form a closed space), the air in the closed space and the air in the vacuum bag are evacuated through the vacuum pump 1 83, and then through the external pumping connecting tube. If the external external pumping tube is inserted into the external pumping connecting tube and the vacuum tank (or vacuum bag) is evacuated using the external external pumping tube, the air and soup in the vacuum tank (or vacuum bag) are discharged through the external pumping connecting tube and the vacuum pump 1 83. When the trigger part 7 of the lifting movable part 5 triggers the limit device 6, the limit device 6 will deflate the vacuum chamber assembly through the vacuum pump 2 84 and the cylinder 2 82, which realizes automatic extraction and deflation, which is more conducive to meeting the use requirements. It is to be noted that the cylinder 1 81 and the cylinder 2 82 and the vacuum pump 1 83 are respectively connected to the electromagnetic valve 85 and the vacuum chamber assembly and the vacuum pump 2 84 and the vacuum chamber assembly through pipelines, which is conducive to extraction and deflation.

[0031] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, a pressure sensor 86 is provided on the base 1, and the pressure sensor 86 is used to detect the pressure in the vacuum chamber assembly. The pressure sensor 86 is connected to the control unit 3, and the control unit 3 is connected to the cylinder 2 82 and the vacuum pump 2 84. This is conducive to giving a signal to the control unit 3 through the pressure sensor 86, and the cylinder 2 82 starts to work, which greatly improves the sealing performance.

[0032] like Figure 2 and Figure 5 As shown, a circuit board 9 is arranged on the base 1, and a function button (not shown in the figure) is arranged on the base 1 or the lower cover 2, and the function button is connected to the circuit board 9. The function button may have a switch key. For example, when the switch key is pressed, the circuit board 9 will be triggered to work accordingly, so that the corresponding work of the lifting and lowering vacuum sealing device is triggered by the circuit board 9.

[0033] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the existing technology. Since the cooperation between the vacuum chamber assembly and the drain trough is the existing technology, no further elaboration is made here.

Workers can complete normal operation of it according to the existing technology manual.
