Abstract: A manufacturing process for a food warming pad includes the following steps: a pad body with a groove formed on a second surface is manufactured by an integrated molding process; after the heating wire is embedded in the groove, an encapsulation glue is coated, and a drying operation is performed; after the encapsulation glue is completely cured, a controller is installed; and then, a test is performed to obtain a qualified food warming pad.

Abstract: A modular food warming pad includes a first heating pad and a plurality of second heating pads. The first heating pad includes a first support panel, a controller and a first connector electrically connected to each other. Each second heating pad includes a second supporting panel, a second connector, and a third connector electrically connected to each other. The first heating pad and the second heating pads are arranged in a first direction. The first connector of the first heating pad is electrically connected to the second connector of an adjacent second heating pad; the third connector of one second heating pad is electrically connected to the second connector of its adjacent second heating pad.

Abstract: A flexible heat preservation board with heating wire encapsulated therein includes a heating pad, a heating wire and a liquid adhesive. A first side of the heating pad is defined with a groove and arranged with a plurality of projections. The heating pad is provided with a power supplier. Inner surfaces of the groove are provided with a first protrusion and a second protrusion respectively. A bottom surface of the groove, lower surfaces of the first protrusion and the second protrusion define an open accommodating space for receiving the heating wire. A first gap is formed between the first protrusion and the heating wire, a second gap is formed between the second protrusion and the heating wire. The liquid adhesive encapsulates the first protrusion, the second protrusion, and the heating wire in the groove. Both the heating pad and the heating wire are flexible.

Abstract: The present disclosure relates to the technical field of heat preservation boards and, particularly to a flexible heat preservation board, including a heating pad and a heating wire, in which the heating pad is formed with a limiting groove for threading the heating wire, the limiting groove is uniformly distributed around the heating pad, the heating pad is provided with a power supplier to which an end of the heating wire is connected, a side of the heating pad is formed with a plurality of protruding structures having a same height, and the heating pad and the heating wire are both made of flexible materials. The proposed disclosure solves the problem that most of the existing meal heating devices are made of metal or glass materials, which, due to their high rigidity, lead to occupying a large space when they are not required for use and are difficult to store.

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: 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.
