Abstract: The present invention discloses an external vacuum sealer comprising a case, a heating adhesive strip, a heating band assembly and a lifting mechanism that all are installed in the case. The heating band assembly is set up underneath the heating adhesive strip, and is attached to the lifting mechanism. A plastic bag is disposed between the heating adhesive strip and the heating band assembly; the lifting device is able to drive the heating band assembly up such that the heating band assembly approaches the heating adhesive strip until the plastic bag is compressed and sealed; the lifting mechanism is also able to drive the heating band assembly down such that the heating band assembly can be far from the heating adhesive strip and the plastic bag. The lifting mechanism includes a pump unit that connects to the air pipe via the magnetic valve. The present invention enhances the production efficiency.

Abstract: The invention discloses a vacuum low-temperature cooker comprising a housing, an inner pot comprising a basin and a lid, and a heating circulation system comprising a heater, a water pump and connecting pipes. The heater, the water pump and the basin are connected in series through the connecting pipes to construct a closed circulation loop. The basin is equipped with an inlet and an outlet associated with the connecting pipes. The invention makes the temperature inside the inner pot to be constant, such heating circulation loop also makes the water therein to absorb 95% energy emitted by the heater with energy saving. Meanwhile the heater is mounted outside the inner pot, such arrangement makes the inner pot having a maximum space to cook and clean.

Abstract: A vacuum storage bag comprising a plastic bag film, an exhaust valve and a pressure-sealing zipper is provided. The exhaust valve includes a valve plate, a valve seat and a valve cover, the exhaust valve configured between an upper film and a lower film of the plastic bag. One side of the valve seat is bonded to an inner surface of one of the films. Numerous grooves are spread over the other surface of the valve seat, and are wrapped tightly by the valve cover. A cone head is raised in the center of the valve plate between valve seat and the film, and tightly mates with a conical boring of the valve seat. A narrow air duct is formed by the grooves of valve seat and cover, and could filter air in the bag to prevent dust from entering sealing surface between the valve plate and the valve seat.
