Abstract

The invention provides an electric heating film, which comprises a flexible film body and a connector. Wires are distributed on the flexible film body, heating resistive layers connected with the wires are laid on the flexible film body, and the connector is connected with the wires. According to the scheme of the electric heating film, the heating resistive layers connected with the wires are laid on the flexible film body and are formed by painting nano carbon series resistive pastes, so that the thickness of the electric heating film can be effectively controlled and thinning and special shaping of the electric heating film can be realized easily. In addition, the heating resistive layers of the electric heating film are arranged optionally, the electric heating film is simple in manufacturing process, low in cost, favorable for automatic production, high in heat efficiency and easy to control power when in use; the heating resistive layers are free of looseness, short circuit, broken circuit and the like, and accordingly safety of using is improved.

Description

technical field [0001] The invention relates to electric heating technology, in particular to an electric heating diaphragm. Background technique [0002] For externally applied medicines, in order to improve their efficacy, a heater is generally used to heat the medicines. The heating plate of the existing heater is made by smelting nickel and chromium into an alloy according to a certain proportion, and then the resistance wire formed by strong extrusion is made into a spiral or strip shape, and is wound or attached to a rigid insulation board according to the rated power requirement. On the board, the rigid insulating board is generally selected as a mica board, and then the two sides of the rigid insulating board are respectively covered with insulating boards for insulation protection. [0003] There are following deficiencies in the prior art: [0004] 1. Limited by the shape of the resistance wire, it is difficult to realize thinning and specialization of the heatin...
