The item is an easy-to-operate bag sealer that can inflate as well as vacuum, for normal household use, to keep foodstuff fresh. In the front portion of the surface of the body is the bottom frictional pressboard bar that has a frictional surface on one side. Under the cover, facing the frictional surface of the bottom frictional bar is fitted with the upper frictional pressboard bar for vacuuming or inflating. The diagonal frictional force produced by the frictional surface of the bottom frictional pressboard bar and that of the upper frictional pressboard bar is enough to enable the cover to stay closed during the process of realizing the vacuuming and inflating functions. A heat wire is located in parallel to and in the front of the bottom frictional pressboard bar and under the cover is fitted with another coordinating pressboard bar for bag sealing. Also included is an indirect switch to be pressed down to activate the vacuuming and inflating functions control, placed underneath the body, through a hole opened on the body at a corner position formed by the bottom frictional pressboard bar and the surface of the body. Under the cover, at the exact position facing the hole on the body through which the indirect switch is protruding, a cave-like opening is made on the upper frictional pressboard bar or wherever deemed appropriate. The coordinating factor of this cave-like opening and the indirect switch has a procedural function to control the activation of vacuuming and inflating.
