AI Technical Summary
Traditional electric blankets use a single temperature sensor, which makes it difficult to accurately monitor the temperature. This can lead to localized overheating or underheating, uneven heating wires that are prone to oxidation, short lifespan, and safety hazards.
It employs a distributed temperature sensor array and multiple parallel carbon fiber heating wires, combined with a high-temperature resistant insulation layer and control box, to achieve all-round temperature monitoring and uniform heating.
It achieves precise and uniform control of the surface temperature of electric blankets, improving user comfort and safety, reducing the risk of failure, and enhancing insulation performance and service life.
