Abstract:
1. A vacuum sealer comprises: a base member including a front portion and a rear portion, the front portion formed with a platform having a first sealing ring secured on the platform, the platform being hollow and a drawing hole defined in the top of the platform within the first sealing ring, a heating plate laterally secured on a front edge of the platform, the rear portion of the base member formed with a support, the rear portion of the base member divided into a receiving space and a container, wherein the receiving space is provided to receive a pumping device and the container is adapted to receive a tool and a power cord, an opening defined in one side of the rear portion of the base member and communicating with the container, a door pivotally mounted adjacent to the opening for closing the opening, a bore defined in and extending through the door for a user to easily operate the door and a magnet secured on a free end of the door for selectively holding the door in place; the pumping device mounted on the support, the pumping device includes a pump mounted on the support and a tube, the tube having a first end extending into the hollow platform and communicating with the drawing hole, and a second end connected to the pump, a pressure sensor mounted on the support and connected to the tube, an electromagnetic valve mounted on the support and electrically connected to the pressure sensor, electromagnetic valve guiding the air into the tube to relieve the vacuum condition in the tube when sealing of the plastic bag is finished; and a transparent presser having a rear side pivotally mounted on the platform and selectively pressed on the top of the platform, a second sealing ring secures on a bottom of the presser and fully airtightly abuts the first sealing ring, and the pressure sensor provided to sense the pressure between the first sealing ring and the second sealing ring when the presser is pressed on the platform, a thermal insulator wicker laterally attached to the bottom of the transparent presser and relative to the heating plate to prevent the heat from being transferred from the heating plate to the presser.
