Water-heating and water-cooling dual-purpose electric blanket

Abstract

A water-heating and water-cooling dual-purpose electric blanket comprises an upper blanket surface, a lower blanket surface, a heating layer, a temperature sensor, a temperature monitoring module, a refrigerating device, a switch and sealing pins. The heating layer comprises a surface layer, an inner layer and an interlayer, the interlayer is provided with a heating pipe in which a heating wire is arranged, and a shielding wire is wound around the heating wire; the outer wall of the heating pipe is made of an insulating material, the heating pipe is sleeved with a sleeve pipe with a cavity reserved between the heating pipe and the sleeve pipe, and the cavity is filled with heat transfer liquid; the two ends of the sleeve pipe are connected with three-way pieces in an insertion mode respectively, the other two joints of each three-way piece are connected with an extension pipe and a tightening cap respectively, the two ends of the heating pipe are plugged by the sealing pins, and the tightening caps are in screw connection with the sealing pins through threads; the extension pipes are connected with the refrigerating device; the heating wire is led out from the sealing pins and connected with a power line, and a circuit breaker is arranged on the power line; the temperature sensor is arranged on the heating layer and connected to the temperature monitoring module through a wire, and the temperature monitoring module is connected with the switch; the switch is connected with an external power supply through a plug. The water-heating and water-cooling dual-purpose electric blanket can perform refrigerating or heating selectively and is safer to use.

Description

technical field [0001] The invention relates to an electric heating blanket, in particular to a water heating and water cooling dual-purpose electric heating blanket. Background technique [0002] At present, domestically known electric blankets are composed of electric heating wires and cladding layers. Although they can be used for heating, they can produce harmful electromagnetic radiation, which can harm the body and make people feel uncomfortable such as dryness, thirst, dry eyes, and dizziness. Feeling, and no full line safety protection function, non-radiation electric blanket or magnetic therapy electric blanket products reduce electromagnetic radiation, solve the interference of some low-frequency electromagnetic waves, but the controller structure is complex, the cost of electric blankets is high, and it is easy to damage. [0003] The connection between the heating wire and the power cord of the existing electric blanket is simply wrapped, and the firmness and ins...

[0002] At present, domestically known electric blankets are composed of electric heating wires and cladding layers. Although they can be used for heating, they can produce harmful electromagnetic radiation, which can harm the body and make people feel uncomfortable such as dryness, thirst, dry eyes, and dizziness. No radiation electric blanket or magnetic therapy electric blanket products reduce electromagnetic radiation and solve the interference of some low-frequency electromagnetic waves, but the controller has a complex structure, high cost of electric blankets, and is easily damaged

[0003] The connection between the heating wire and the power cord of the existing electric blanket is only simply wrapped, and the firmness and insulation performance are not high, resulting in a relatively large safety hazard during use
