Description

Press vacuum machine

The present invention relates to the field of vacuum technology, and in particular to a hand-held push type vacuum machine.

Since the deterioration of food mold is mainly caused by microbial activity, most microorganisms need oxygen for survival, and vacuum packaging uses this principle to remove the oxygen in the vacuum bag or vacuum box containing the food, so that the microorganisms can not survive. In order to achieve the purpose of food preservation. In addition to inhibiting the growth and reproduction of microorganisms, vacuum is another important function to prevent food oxidation. Since oil-ester foods contain a large amount of unsaturated fatty acids, they are oxidized by oxygen, which causes food to deteriorate and deteriorate. In addition, oxidation can also cause vitamin loss and darkening of the color. Therefore, vacuum packaging can effectively maintain the original color, aroma, taste and nutritional value of the food for a long time.

In order to enable people to conveniently vacuum the vacuum bag or vacuum box containing food in daily life. Liu Dongxin's Chinese Utility Model Patent No. 200620003728.0 is used for the vacuuming machine of the bead type sealed bag; Chinese utility model patents 200720055173.9, 200820049639.9 and 201020270820.X created by Qiu Yuhui are a household vacuum machine; The Chinese utility model patent No. 201020557331.2 created by Xinchun is a hand-held vacuum pump; all of them use a button to start an air pump to perform a vacuuming action.
