[0002] Traditional electric blankets have relatively single functions, mainly relying on simple switch control to achieve heating, lacking intelligent interaction and management mechanisms. In terms of safety, when users accidentally fold and use the electric blanket, or when heat dissipation is poor due to local pressure, it is extremely easy to cause overheating, and even serious safety accidents such as fires. Moreover, existing electric blankets generally lack effective abnormal detection and automatic power-off protection measures and cannot respond to emergencies in a timely manner.

[0003] In terms of energy utilization efficiency, during the operation of traditional electric blankets, a large amount of heat generated by the heating wires is dissipated into the surrounding environment and not fully utilized, resulting in energy waste.

[0061] A high-temperature melting layer 3, covering the upper surface of the heating wire assembly 2 and forming physical contact with the heating wire assembly 2;

[0062] A contact circuit 4, arranged on the upper surface of the high-temperature melting layer 3;

[0063] A controller 5, the controller 5 is communicatively connected to the contact circuit 4, the heating wire assembly 2, the voice interaction module 6, the abnormality detection and processing module 7, the remote communication module 8 and the self-checking and guiding module 9;

[0064] It further includes a U-shaped heat insulation rotating assembly 10 sleeved outside the heating wire assembly 2;

[0065] A waste heat recovery structure 11 is arranged at the bottom of the U-shaped heat insulation rotating assembly 10, and the U-shaped heat insulation rotating assembly 10 is communicatively connected to the controller 5;

[0066] A spacer layer 12 is covered on the contact circuit 4, a capacitive touch sensing layer 13 is laid on the spacer layer 12, an outer surface layer 14 is arranged on the capacitive touch sensing layer 13, and the capacitive touch sensing layer 13 is communicatively connected to the controller 5.

[0067] First, arrange multiple heating wire assemblies 2 accurately on the base layer 1 according to the design requirements, ensuring that the spacing between the heating wire assemblies 2 is uniform to guarantee the uniformity of heating.

[0068] Cover the upper surface of the heating wire assemblies 2 evenly with the high-temperature melting layer 3 using a specific process, making it closely fit with the heating wire assemblies 2 to form good physical contact.

[0069] On the upper surface of the high-temperature melting layer 3, set up the contact circuit 4 through the printed circuit board process or other suitable methods, ensuring that stable electrical signal transmission can be carried out between the contact circuit 4 and the high-temperature melting layer 3.

[0070] Connect the controller 5, the voice interaction module 6, the anomaly detection and processing module 7, the remote communication module 8, and the self-checking and guiding module 9 to the contact circuit 4 and the heating wire assemblies 2 through corresponding communication lines, ensuring accurate and stable data transmission between the modules.

[0071] Install the rotary motor 101 and the rotating shaft seat 102 at intervals at the predetermined positions on the base layer 1. Install the U-shaped heat insulation part 103 at the output end of the rotary motor 101 and ensure that the U-shaped heat insulation part 103 can rotate flexibly around the rotating shaft seat 102. Install the detection contacts 104 at appropriate positions on the rotary motor 101 and the rotating shaft seat 102 respectively, making it able to cooperate with the high-temperature melting layer 3 and the contact circuit 4.

[0072] Install the waste heat recovery structure 11 at the bottom of the U-shaped heat insulation and rotation assembly 10. Connect the thermoelectric generator 111 to the U-shaped heat insulation part 103 through the thermal conductive interface layer to ensure efficient heat conduction. Electrically connect the energy storage unit 112 to multiple thermoelectric generators 111 and connect it to other modules such as the controller 5 and the voice interaction module 6 through lines to realize the storage and distribution of electric energy.

[0073] Cover the contact circuit 4 with the isolation layer 12, the capacitive touch sensing layer 13, and the outer surface layer 14 in sequence, ensuring that the layers are closely attached to each other. The matrix electrodes 131 array of the capacitive touch sensing layer 13 is connected to the controller 5 through wires to realize the accurate detection and transmission of human contact signals. At the same time, install the electromagnetic shielding layer between the base layer 1 and the heating wire assemblies 2, ensuring that the metal mesh is firmly connected to the grounding terminal and extends to the edge of the electric blanket for connecting to the external grounding device.

[0074] Working process of the electric blanket: In the startup stage, when the electric blanket is powered on and started, the voice interaction module 6 immediately plays the startup safety prompt voice to remind the user to use the electric blanket correctly. At the same time, the self-checking and guiding module 9 starts to detect the initial resistance of the heating wire assemblies 2 and stores the detection data as the reference data for subsequent anomaly detection.

[0075] During the normal operation stage, during the normal operation of the electric blanket, the abnormal detection and processing module 7 continuously monitors the data of the temperature sensors in each area in real time, and the capacitive touch sensing layer 13 detects the human contact position and area in real time. According to the detection results of the capacitive touch sensing layer 13, the controller 5 divides the electric blanket into an occupied area and an unoccupied area. For the unoccupied area, the controller 5 sends a rotation instruction to the U-shaped heat insulation rotating assembly 10 to rotate the U-shaped heat insulation member 103 by an angle, adjust the angle of the upper opening, reduce the heat of the heating wire assembly 2, and reduce heat dissipation; for the occupied area, the controller 5 combines the human position data and the temperature sensor data, and uses the PID control algorithm to adjust the heating power of the heating wire assembly 2, and dynamically adjusts the target temperature according to the human contact area. During this process, the waste heat recovery structure 11 collects the heat at the bottom of the U-shaped heat insulation rotating assembly 10 in real time, and the controller 5 dynamically adjusts the rotation angle of the U-shaped heat insulation rotating assembly 10 according to the ambient temperature and the working state of the heating wire assembly, optimizes the hot end temperature of the thermoelectric generator 111, and realizes the efficient recovery and utilization of waste heat.

[0076] During the abnormal handling stage, when the abnormal detection and processing module 7 detects that the temperature in a certain area exceeds the preset threshold of 60 °C, at the same time, if the high-temperature melting layer 3 melts due to overheating, it will be electrically connected to the contact circuit 4, and the electrical signal will be transmitted to the controller 5 through the detection contact 104, and it is determined as an overheating abnormality. At this time, the voice interaction module 6 immediately plays an emergency prompt voice to remind the user to check the electric blanket.

[0077] The controller 5 further uses the contact circuit 4 and the high-temperature melting layer 3 to jointly judge whether the heating wire assembly 2 is locally overheated due to misoperation, and starts a 300-second user self-check countdown. If no confirmation signal from the user is received before the countdown ends, the controller 5 will cut off the power supply of the heating wire assembly 2 in the abnormally heated area, maintain the low-temperature operation state of other normal areas, and inform the user through the voice interaction module 6 that they can remotely restore through after-sales.

[0078] Subsequently, the controller 5 sends an abnormal data packet to the factory server through the remote communication module 8, and the after-sales customer service contacts the user according to the work order pushed by the server. After confirming that the user's self-check is okay, the after-sales customer service sends a recovery instruction to the controller 5 through the factory server. The controller 5 performs a secondary verification before recovery, checks the resistance value of the area to be recovered and the state of the high-temperature melting layer 3, and gradually restores the power supply of the heating wire assembly 2 in this area to the set power after passing the verification, so that the electric blanket returns to the normal working state.
