Abstract: A heating assembly, comprising a base plate, the base plate being provided with a plurality of ceramic heating sheets, the ceramic heating sheets being spaced apart side by side and being connected in parallel, and a heat conduction structure being provided over the ceramic heating sheets. An electrothermal furnace having the heating assembly is also provided.

Abstract: The trash can includes a can member, a fastener member for fixing a trash bag's opening, a hoist member, and a thermal sealing member mounted on the can member. The fastener member is detachably embedded in the thermal sealing member, the hoist member engages the thermal sealing member into vertical movement. The can member is also configured with a pump element, a sensor element, a power element, and a controller element. The trash bag is stretched open on the fastener member. The pump element draws air out of the can member and the trash bag is automatically expanded. The sensor element detects that the trash bag has expanded and the pump element stops pumping. The hoist member moves the fastener member upward to further expand the trash bag. The thermal sealing member automatically shrinks and seals the opening of the trash bag.

Abstract: An ultra-thin heating device includes an upper heating pad, a lower heating pad, at least one electric heating piece and a power supply. The electric heating piece is installed at a preset position between the upper heating pad and the lower heating pad. The electrothermal sheet is electrically connected with the power supply. The upper heating pad and the lower heating pad are made of soft material. When a food needs to be heated, the food is placed on the preset position of the upper heating pad corresponding to the at least one electrothermal sheet, and the power supply provides electric power to the at least one electrothermal sheet to heat the food. Because the upper heating pad and the lower heating pad are made of soft material, when not in use, the ultra-thin heating device can be folded or rolled up for storage.

Abstract: A glue jamming prevention structure of a laminator is disclosed, having a main structure that includes a housing, an entry opening and an out-feeding opening respectively arranged at two sides of the housing, a left side board, a right side board, and a power element arranged in the housing. A first entry driving axle, a second entry driving axle, a first out-feeding driving axle, a second out-feeding driving axle, a left-side elastic assembly, and a right-side elastic assembly are arranged on the left side board and the right side board. A first driving belt is arranged on the first entry driving axle and the first out-feeding driving axle. A second driving belt is arranged on the second entry driving axle and the second out-feeding driving axle.

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.
