Or one end of the conduction tube 3 is fixedly connected to the suction port of the vacuum pump at all times, and one end of the conduction tube 3 is a movable end. When in the working state, the movable end of the conduction tube 3 and the suction port 8 are guided. When the connection is made, the movable end of the conduction tube 3 is disconnected from the suction port 8 when in the non-operating state. Or one end of the conduction tube 3 is fixedly connected to the suction port 8 at a fixed end, and one end of the conduction tube 3 is a movable end. When in the working state, the movable end of the conduction tube 3 and the suction port of the vacuum pump The conductive connection is disconnected from the suction port of the vacuum pump when in the non-operating state. Of course, instead of using the vacuum box 2, one end of the air guiding tube 3 can be directly connected to the air inlet of the vacuum pump, and the other end of the air guiding tube 3 can be directly placed in a vacuum bag or a packaging box for vacuuming.

When the vacuum packaging machine is in the working state, the suction port of the vacuum pump in the main box 1 and the suction port 8 in the vacuum box 2 are electrically conducted through the air guiding tube 3.

The vacuum box 2 includes an upper lid 21 and a lower lid 22, and the upper lid 21 is detachably coupled to the lower lid 22 and can be snapped up and down into a sealed cavity. When the upper cover 21 and the lower cover 22 are fastened together, a relatively sealed cavity space is formed.

a heating wire 4 is disposed outside the lower surface of the upper cover 21, and the heating wire 4 is electrically connected to the power supply device through a detachable wire device; the heating device is disposed outside the upper surface of the lower cover 22 4 adapted high temperature strip 5 . When the machine is in the working state, the power supply unit in the main box 1 and the heating wire 4 in the vacuum box 2 are electrically connected by the above-mentioned detachable electric wire device. When the machine is in an inoperative state, that is, the main box 1 and the vacuum box 2 are independent of each other, the detachable electric wire device is detached from the main box 1 and the vacuum box 2, and placed separately. Or one end of the detachable wire device is a fixed end, and is always fixedly connected to the power supply device; and the other end of the wire device is a movable end. When the heating wire needs to be energized, the movable end is electrically connected with the heating wire. In the non-operating state, the movable end of the wire device is disconnected from the heating wire. Conversely, the fixed end of the wire device can be fixedly connected to the heating wire at all times; and the other end of the wire device is a movable end. When the heating wire needs to be energized, the movable end is electrically connected to the power supply device, and is in a non-working state. When the movable end of the wire device is disconnected from the power supply device.

After the upper cover 21 and the lower cover 22 are fastened, the sealing portion of the packaging bag is pressed between the high temperature rubber strip 5 and the heating wire 4, and the heating wire 4 is activated at this time, and the heating wire 4 is heated to be pressed at the high temperature adhesive. The package bag between the strip 5 and the heating wire 4 is hot melted to achieve the sealing of the package.

A groove 6 is provided inside the upper surface of the lower cover 22, and a seal ring 7 fitted to the periphery of the groove 6 is provided inside the lower surface of the upper cover 21. A sealing sponge 9 is provided around the periphery of the groove 6.
