As shown in fig. 1, an intelligent fast-heating high-efficiency electric blanket comprises a blanket body 1, a heating wire 2, a junction box 3, a flexible lead 4, a controller 5 and a power line 6, wherein the heating wire 2 and the junction box 3 are fixed on the blanket body 1, the heating wire 2 is used for heating the blanket body 1, the junction box 3 is mainly used for electrically connecting the heating wire 2 and the flexible lead 4, the flexible lead 4 is used for electrically connecting the junction box 3 and the controller 5, the controller 5 is used for controlling the power supply and the temperature of the electric blanket, and the power line 6 is used for inputting an alternating current 220V power supply.
As shown in fig. 2 and 3, the junction box includes a heating wire head 7, a heating wire tail 8, a temperature sensor 9, a temperature fuse 10, a circuit board 11, a plastic housing 12, and a multi-core flexible conductor 13, wherein an insulating layer of the heating wire head 7 is in close contact with the temperature fuse 10, an insulating layer of the heating wire tail 8 is in close contact with the temperature sensor 9, the temperature sensor 9 is used for collecting the temperature of the heating wire tail 8, the temperature fuse 10 is connected in series in a circuit of the heating wire head 7 and is used for overheat protection of the heating wire head 7, and the multi-core flexible conductor 13 is used for supplying power to the heating wire and feeding back the temperature value of the heating wire to the controller. The controller circuit comprises an input power supply, a power supply switch, a temperature regulating switch, a temperature control switch, a protection switch, a current fuse, a voltage stabilizing circuit, a timing circuit, a temperature regulating circuit, an intelligent temperature control circuit, an over-temperature protection circuit, an overheating protection circuit and a broken wire protection circuit.
The current fuse is respectively electrically connected with the power switch, the protection switch, the temperature fuse and the voltage stabilizing circuit, the power switch is electrically connected with the input power supply, and the voltage stabilizing circuit is electrically connected with the timing circuit.
The heating wire is respectively and electrically connected with the temperature fuse, the temperature control switch, the overheating protection circuit and the broken wire protection circuit.
The temperature adjusting circuit is electrically connected with the temperature adjusting switch, the timing circuit and the intelligent temperature control circuit respectively, and the intelligent temperature control circuit is electrically connected with the temperature control switch.
Wherein the temperature sensor is respectively electrically connected with the intelligent temperature control circuit and the overtemperature protection circuit.
The protection switch is respectively and electrically connected with the overtemperature protection circuit, the overheat protection circuit and the broken wire protection circuit.
The utility model discloses a theory of operation is:
when the temperature of the heating wire reaches a set value, a temperature sensor in a junction box feeds back the temperature value to the intelligent temperature control circuit and the over-temperature protection circuit through a multi-core flexible wire, the intelligent temperature control circuit closes the temperature control switch, the heating wire stops heating, and when the temperature of the heating wire is lower than the set value, the heating wire restarts heating.
Because the electric blanket adopts advanced intelligent temperature control technology and perfect multiple protection technology, the heating wire can select larger electric power (4W-8W per meter) and larger average input power (80W-150W for one person and 160W-300W for two persons), the electric blanket can reach ideal heating temperature after being electrified for about ten minutes, and the heating wire is always in an intermittent heating state after the electric blanket is electrified, so the heating efficiency is higher, the electricity-saving effect is obvious, and the average electricity-saving rate can reach more than 30 percent compared with the common electric blanket.
If the intelligent temperature control circuit is in failure and the temperature of the electric blanket exceeds a set value, a feedback signal of the temperature sensor enables the overtemperature protection circuit to trigger a protection switch (silicon controlled rectifier) to be conducted, at the moment, the current fuse is fused due to overcurrent, and the heating wire stops heating. If the overtemperature protection circuit and the intelligent temperature control circuit simultaneously break down, when the temperature of the heating wire reaches the specified value of the temperature fuse in the junction box, the temperature fuse is immediately fused, and the temperature fuse is connected in series in the circuit of the heating wire, so that the power supply of the heating wire is cut off. If the electric blanket is curled, folded and stressed when in use or the heating wire is in abnormal working states such as wire collision, crossing and the like, the local temperature of the heating wire is overheated, at the moment, a melting layer in the double-layer heating wire melts, the metal wire and the heating wire are in short circuit, the voltage on the metal wire is fed back to the overheating protection circuit to trigger the protection switch to be conducted, at the moment, the current fuse is fused due to overcurrent, and the heating wire stops heating. When the heating wire in the heating wire is accidentally broken, in order to avoid fire caused by electric sparks or electric arcs at the broken part, the broken wire protection circuit immediately triggers the protection switch to be conducted, the current fuse is fused due to overcurrent, and the power supply of the heating wire is cut off. After the intelligent temperature control technology and the multiple protection technology are adopted, the heating wire insulating layer avoids overheating damage, so that the accident that the electric blanket hurts people is effectively restrained.
If the electric blanket forgets to turn off the power switch after being used, in order to save electric energy and eliminate potential safety hazards, the timing circuit automatically turns off the temperature adjusting circuit, the intelligent temperature control circuit and the temperature control switch after the electric blanket is electrified for 8-10 hours, and the heating wire stops heating due to power failure.
