External pumping vacuum packaging machine

The utility model relates to an external pumping vacuum packaging machine, which comprises a machine body and a vacuum cover hinged to each other. The vacuum cover and the vacuum chamber in the machine body cooperate with each other, and the body shell on one side of the vacuum chamber is connected with the worktable surface of the separate body. The height of the worktop is lower than the upper plane of the vacuum chamber. The utility model overcomes the troublesome operation and usage of the ordinary external vacuum packaging machine in the prior art, and the vacuum chamber is easy to leak due to an operation mistake, thereby reducing the vacuuming effect of the vacuum packaging machine. Through the above design, the utility model is in use. The packaging bag can be placed on the work surface so as to free up the hand to vacuum the operation at the same time, which greatly improves the effect of vacuum, and has the advantages of simple structure, convenient operation, and high reliability.
