Abstract
The utility model relates to an electric blanket capable of being prevented from burning due to folding. The electric blanket comprises an electric blanket main body and a control switch connected with the electric blanket main body; the control switch is composed of a heat conduction wire, controllable silicon, a diode, a resistor, a capacitor and a fuse; the heat conduction wire comprises an insulating core wire, a temperature sensing wire and a heating wire; a fusible insulation layer is arranged between the insulating core wire and the temperature sensing wire; the heating wire is connected with a power supply output wire; one end of the temperature sensing wire is connected with the diode, and the other end of the temperature sensing wire is hung in the air; and the control terminal of the controllable silicon is connected with the temperature sensing wire by being connected with the diode and the current-limiting resistor in series. When the temperature of the heating wire increases caused by gravity, densely winding, lighting, rolling, folding and the like, the fusible insulation layer melts, then the temperature sensing wire is enabled to be in contact with the heating wire are enabled so as to cause short circuit, further the current of the fuse increases, the power supply is cut off, and the electric blanket stops working; therefore, burning accidents caused by incorrect use methods are effectively avoided, and the purposes of safety and burning prevention can be achieved.
Description
Technical field
The utility model relates to a kind of electric blanket, relates in particular to a kind of anti-folding combustion electric blanket.
Background technology
Electric blanket adopts traditional mode always for a long time; the common secure line protection electric blanket of unalterable employing promptly adopts a fuse to play the route protection effect; in this protection circuit exists and sentences from terminal box to heating wire 15CM; the electric blanket hot-spot takes place can not get protection; therefore exist some potential safety hazards that cause because of the improper using method of user; use the easy breaking out of fire of this electric blanket, electric shock and other safety accidents, and cause life and property loss.
The utility model content
The utility model provides a kind of safe, practical anti-folding combustion electric blanket in order to overcome the above problems.
The technical solution of the utility model is: comprise the electric blanket main body, also comprise the gauge tap that is connected with the electric blanket main body, described gauge tap is made up of hotness line, controllable silicon, diode, resistance and electric capacity and fuse, described hotness line contains insulation heart yearn, temp.-sensing wire and heating line, be provided with fusible insulating barrier between insulation heart yearn and the temp.-sensing wire, the heating line is connected with power supply output line, temp.-sensing wire one end is connected with diode, the other end is unsettled, and the silicon controlled control end links to each other with temp.-sensing wire by a diode of polyphone and a current-limiting resistance.
The utility model when because of gravity, closely cause generating heat the line temperature when raising around, sparking, volume, reason such as folding, fusible insulating barrier promptly melts, cause temp.-sensing wire to contact and produce short circuit with the heating line, the fuse electric current increases and cuts off the power supply, electric blanket promptly quits work, the pyrophoricity accident of having avoided effectively causing because of wrongful using method takes place, and reaches the anti-flaming purpose of safety.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is the electric blanket main body among the figure, the 2nd, and controllable silicon, the 3rd, diode, the 4th, resistance, the 5th, electric capacity, the 6th, fuse, the 7th, temp.-sensing wire, the 8th, heating line.
The specific embodiment
Anti-folding combustion electric blanket, comprise electric blanket main body 1, also comprise the gauge tap that is connected with electric blanket main body 1, described gauge tap is made up of hotness line, controllable silicon 2, diode 3, resistance 4 and electric capacity 5 and fuse 6, described hotness line contains insulation heart yearn, temp.-sensing wire 7 and heating line 8, be provided with fusible insulating barrier between insulation heart yearn and the temp.-sensing wire 7, heating line 8 is connected with power supply output line, temp.-sensing wire 7 one ends are connected with diode 3, the other end is unsettled, and the control end of controllable silicon 2 links to each other with temp.-sensing wire 7 by a diode 3 of polyphone and a current-limiting resistance 4.
