How to do if the temperature not high at heating sheet when use on electric scarf ?
This is a professional problem, perhaps only the industry working person knows the reason, according to market data analysis, at present, any wearable, when the manufacturer designs, the use of 5-7.4V low-voltage power supply may be greater than 90% probability, what is the reason ? Two words on Chinese is "safety" a product to do well, consumers are willing to pay can, the product to do in Not good, it will not hurt people, on the contrary, such as "220-110V" is not good, its own voltage, looking at people feel unsafe, not really unsafe, in fact, there are still some manufacturers do very good...
How many degrees is the temperature design of the heating sheet above the electric scarf more appropriate? Generally speaking, the temperature limit that the human body can withstand will not exceed 65 degrees, some manufacturers will design a higher temperature, it is not recommended to do so, the neck area of the human body is very tender, long-term high temperature hot apply, will lead to red skin, not conducive to the health of the skin .
Some people will design the temperature very low, about 40 ° C or so, but the winter temperature is very slow, it will lead to low product sales, this situation is not considered the factors of the season, summer or autumn production, winter sales, is the premise of the manufacturer in advance, to prepare for winter sales, many manufacturers, did not take into account these problems?
The most ideal temperature for product design is between 55-60 degrees, the winter weather is cold, minus some weather reasons, the temperature conveyed to the human body is about 45-48 degrees, if the human body feels high, through the above temperature control switch, to reduce the temperature, the market for the design of heating pieces, mostly use nanofibers and carbon fibers, of course, carbon fibers will be better . But the production is difficult, many manufacturers are not willing to use, compared with carbon fiber nanofibers, manufacturers will prefer, easy to operate, labor costs will be lower, if I am a consumer, I will choose carbon fiber, good life, no oxidation, infrared, no radiation and so on.
