Abstract
The utility model relates to an electric heating product, particularly an environment protective electric blanket without electromagnetic radiation. The utility model comprises a plug type switching power supply, power supply connecting wires, a temperature controlling switch, a socket connector for a low-voltage power supply which input power for a blanket body, a piece of heat rejection blanket base cloth and built-in electric heating wires. The utility model is characterized in that the electric heating wires are two stranded conducting wires which are provided with insulating layers and spirally wound around a flexible insulation skeleton line, and the wiring connection method of the conducting wires is that the head end of one conducting wire is connected with the tail end of the other conducting wire, and the rest two endpoints after connected are respectively connected with two terminals of the power supply connecting wires. The utility model has the advantages of no electromagnetic radiation, high thermal efficiency and safe use.
Description
Technical field
The utility model relates to a kind of electromagnetic-radiation-free environmental protection electric blanket, belongs to the electric heating product technical field.
Background technology
Electric blanket becomes the electric heating goods that consumers in general like because its economy and durability is easy to use.Traditional electric blanket is directly to generate heat by heating wire, uses the 220V power supply directly to power, and the potential safety hazard of existence is bigger, and the user has the feared state of mind more, and, often there is fire incident to take place.In recent years, people have developed the heating wire that utilizes the LVPS power supply through great efforts, have greatly improved the safety in utilization of electric blanket, but the wiring of this electric blanket and connect electric mode and have defective, electromagnetic radiation is bigger, influences health, therefore, it is promoted and still is subjected to certain limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetic-radiation-free, non-environmental-pollution, simple in structure, environment-friendly type electric blanket that the heat efficiency is high at the deficiencies in the prior art.
For realizing that the technical scheme that the purpose of this utility model is taked is such.A kind of electric blanket, comprise in the structure that plug-type Switching Power Supply, power supply connect low-tension supply connector, heat radiation blanket base cloth material and the in-built electrical heated filament in lead, temperature control switch, the input blanket body, be characterized in: described heating wire is two stranded leads that have insulating barrier that spiral twines on the flexible insulation skeleton line, its mode of connection is that the head end of a wherein lead and the tail end of another lead join, and draws two-end-point then and connects two terminals that power supply connects lead respectively.
The utility model electromagnetic-radiation-free environmental protection electric blanket, used lead is a copper cash, can be enamelled wire or silk-covered wire.
The utility model is compared with conventional art and since the heating wire in the electric blanket adopt two-wire and around, form the opposite coil of both direction, adopt the series wiring mode, magnetic field cancellation, electromagnetic-radiation-free does not cause environmental pollution, and the heating efficiency height, simple in structure, safe and reliable.
