  • the pointed tip of the nozzle insert unit 180C is inserted into the nozzle 241 of the vacuum sealer V3.
  • the sealing ring 82 of the sucking unit 80A is placed above a check valve 95 provided on a cover 93 of an object to be evacuated, that is, a container 90. Subsequently, when the pump of the vacuum sealer V3 is operated, a suction force is transmitted through the nozzle 241.
  • the nozzle insert unit 180C of the connector is forced to be in close contact with the nozzle, thus maintaining a firm coupling between the outer surface of the nozzle insert unit 180C and the inner surface of the nozzle.
  • the suction force of the pump sequentially acts on the nozzle 241, the nozzle insert unit 180C, the tube 80B, and the sucking unit 80A, as shown in FIG. 6d.
  • an upper disc of the check valve 95 of the container 90 is raised to open a path 93b.
  • air is discharged from a body 91 of the container 90 through the nozzle 241, thus creating a vacuum in the container 90.
  • a sealing ring 93a 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 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. Furthermore, 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, and a filter means is coupled to the adapter when filtering liquid, and a vacuum release means is coupled to the adapter when releasing the vacuum, and 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 accorrrplished. Moreover, 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.
  • the connector of the present invention 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 .

Abstract

La scelleuse sous vide de cette invention comprend un corps principal (10) et un capuchon (20) articulé sur ce corps principal. Le chauffage (30) est installé sur le corps principal et est en contact avec un élément de pression (31 situé sur le capuchon de façon à chauffer et sceller l'extrémité ouverte d'un sac. Une pompe à vide (40) est située dans le corps principal afin d'être couplée à une buse d'aspiration (41) communiquant avec l'extrémité ouverte du sac. Par ailleurs, un élément de scellement en ligne droite (11) est situé à une position prédéterminée sur le corps principal et, un autre élément de scellement (21) est situé à une position correspondant à l'élément de scellement en ligne droite. Ces éléments de scellement définissent un canal à vide dans lequel le vide est fait par la pompe à vide, lorsque le capuchon entre en contact avec le corps principal. Une unité de commande permet de commander le chauffage et la pompe à vide.
