The far-infrared thermal electric blanket uses high-density electric carbon wire to quickly heat up to produce high temperatures, which can reach a maximum temperature of 75?C. Exclusive research and development of microcomputer to simulate the wavelength of ?qigong? to produce different changes in high and low temperature. The electric blanket absorbs a large amount of water from the air to produce moisture, offering a new experience of body comfort. Electric blanket function has been widely used in medical rehabilitation. The alternating warm, humid and hot air combined with the far-infrared technology allows the warm, humid and hot air to enter deep cell tissues, promote blood vessel expansion, accelerate blood circulation, and effectively relieve pain in a short time.
