Abstract

The vacuum sealer includes a base, a cover, a vacuuming device, at least a heating device, at least a heat-resistant element wrapping around the heating device, at least a heat insulation element between the base and the heating device, at least a power provision device, and at least a safety breaker device. The safety breaker device includes at least a safety switch, and at least a trigger element. The object to be sealed is placed on the heating device and, as the cover closes the base, the safety switch engages the trigger element to release the safety breaker device and to allow the power provision device to power the heating device. The heat insulation element prevents heat from being conducted to the base. With the dual protection from the safety breaker device and the heat insulation element, safety is enhanced and the power provision device may operate under high voltage.
