The air pump 1 and the heating sealing member (e.g., the heating wire 2) may be implemented by the prior art, and will not be described herein.

In some embodiments, as shown in fig. 2, the first and

second pumping chambers

3, 8 are both rectangular in shape.

In some embodiments, as shown in fig. 2 and 3, the first and

second evacuation chambers

3 and 8 are disposed side by side adjacent to each other or along the length direction 7 of the vacuum bag 6 in order to facilitate the size reduction of the vacuum packaging machine for the sake of more compact structure.

In some embodiments, as shown in fig. 3, the number of the air pumps 1 is one, the vacuum packaging machine includes a first valve 11 and a second valve 12 which are independent of each other, the air pump 1 is connected with the first air-extracting chamber 3 through the first valve 11, the air pump 1 is connected with the second air-extracting chamber 8 through the second valve 12, and the connection schemes are connected with each other through air pipes 16.

2. After the function is started, firstly the control panel sends a signal to control the electromagnetic valve 1 to open, the electromagnetic valve 1 is the second valve 12, the electromagnetic valve 2 is closed, the electromagnetic valve 2 is the first valve 11, at the moment, only the second air-pumping chamber 8 is vacuumized, the second vacuum degree KP2 is continuously vacuumized, at the moment, the vacuum degree of the second air-pumping chamber 8 is lower, and the vacuum degree in the vacuum bag 6 is still one atmospheric pressure, so that the packaging bag in the second air-pumping chamber 8 is bulged.

3. When the second vacuum degree is detected to reach KP1, the air pump 1 is closed, the control system sends a signal to close the electromagnetic valve 1 and open the electromagnetic valve 2, and the vacuum degree of the second air pumping chamber 8 cannot be reduced. At this time, the control system sends a signal, the air pump 1 starts to operate again, the vacuum degree is adjusted by modulating the power of the motor at this time, the vacuum is continuously pumped until the first vacuum degree KP1 is reached by the first vacuum chamber 3, and KP1< KP2, at this time, the vacuum bag 6 in the second vacuum chamber 8 is still in a state of internal air pressure (KP 1) < external air pressure (KP 2), so that the pumped liquid can completely flow into the expanded vacuum bag 6.

4. And after the first vacuum degree KP1 is reached, the control system sends a sealing command, the heating wire 2 works at the moment, and the work is finished after the heating is finished.

In understanding the present disclosure, the above structure may be understood with reference to other embodiments/drawings, if necessary, and detailed description thereof is omitted.
