  • a grasp knob 83 d is provided at a predetermined position on the valve 83 , so that air flows into the internal path of the connector 80 by opening the outer disc 83 a using the grasp knob 83 d.
  • the pointed tip of the nozzle insert unit 180 C is inserted into the nozzle 241 of the vacuum sealer V 3 .
  • the sealing ring 82 of the sucking unit 80 A is placed above a check valve 95 provided on a cover 93 of an object to be evacuated, that is, a container 90 .
  • a sealing ring 93 a is provided on a contact surface between the cover 93 and the body 91 of the container 90 to efficiently seal a gap between the cover 93 and the body 91 .
  • a power switch of a vacuum sealer is turned off.
  • the vacuum pressure acts on the internal path of the connector, it is necessary to release the vacuum pressure acting on the internal path so that the sucking unit 80 A of the connector can be easily separated from the container 90 and the nozzle insert unit 180 C can also be easily separated from the nozzle 241 .
  • the outer disc 83 a is opened using the grasp knob 83 d of the check valve 83 .
  • a vacuum sealer according to the present invention is constructed so that sealing members, especially a sealing member provided on a main body, have a straight-line shape, thus simplifying the construction of the vacuum sealer.
  • the present invention includes a channel volume reducing means to reduce a volume of a vacuum channel which provides an evacuative space for a bag, thus allowing vacuum pressure to be more efficiently concentrated, therefore overcoming drawbacks of a vacuum sealer having a completely open-type vacuum channel and a vacuum sealer having a nozzle inserted into an open end of the bag.
  • the present invention includes a guide means to precisely guide the open end of the bag to the channel with the reduced volume, a liquid guide channel to guide liquid leaking from products contained in the bag during the operation of a pump, and a filter means to filter the liquid to prevent the liquid from flowing from the liquid guide channel through a suction nozzle to the pump.
  • a tube connecting the pump to the suction nozzle communicating with the open end of the bag is exposed to a side of a main body of the vacuum sealer to form cut ends, and an adapter is attached to the cut ends.
  • a plug is coupled to the adapter when using the original function of the vacuum sealer
  • a filter means is coupled to the adapter when filtering liquid
  • a vacuum release means is coupled to the adapter when releasing the vacuum
  • a connector is coupled to the adapter when using the vacuum sealer to create a vacuum in an additional container. Therefore, a multi-purpose vacuum sealer is accomplished.
  • a nozzle insert unit of an auxiliary connector is coupled to the nozzle of a pumping means by inserting an insert part of the nozzle insert unit into the nozzle, so that the auxiliary connector can be utilized for creating a vacuum in an object regardless of the kind of pumping means.
  • a coupling method allows the connector of the present invention to be easily connected to the pumping means.
  • the connector includes a sealing means to achieve an excellent sealing effect during the operation of the pump, and a vacuum release means to allow the sucking unit to be easily separated from the object after the object is evacuated.
