Common temperature control methods for electric blankets in the market?
Market electric blanket common temperature control method, I believe that everyone is estimated to have been in contact with electric blanket, especially the cold weather in the north, most families, have the habit of using electric blanket, then to understand this problem, first of all, we must understand the switch and electric blanket hotline product structure, the common electric blanket control method in the market is roughly as follows!
The electric blanket in the market will probably adopt the following design schemes!
1, ordinary gear switch + ordinary metal hair hot wire
2, intelligent temperature switch + ordinary metal hair hotline
3, intelligent temperature switch + carbon fiber hair hotline
4, special electric blanket switch + double spiral hot wire
1, ordinary gear switch + ordinary metal hair hot wire
Low cost, generally speaking, is the representative of low-end products, most of the design for high and low grade, or push-pull switch, market price competitiveness, quality and safety degree is general, most of the problem electric blanket, is the design of this mode, he does not have an accurate temperature control system, the temperature is all regulated by the level of voltage, the temperature error is also relatively large, in general words to describe is, about how many degrees, can not be described with detailed data, if it is a conscientious enterprise, but also more or less will add a simple temperature protector, to prevent occurrence other than that.
2, intelligent temperature switch + ordinary metal hair hotline
This kind of electric blanket, upgraded in the first case, installed temperature sensor, induction head generally 2-4 varies, mainly sensing the temperature of different positions of the electric blanket, using temperature induction signal, to achieve the purpose of accurate temperature control, temperature general error ± about 3 degrees, the temperature level, can be adjusted arbitrarily by consumers themselves, generally every 5 degrees for an adjustment frequency
3, intelligent temperature switch + carbon fiber hair hotline
This design, similar to the second case, the only strengthening part, is the heating wire inside the electric blanket, from ordinary alloy wire to carbon fiber, this move, a low-end product, directly upgraded to high-end products, generally speaking, carbon fiber has a certain selling point, such as far infrared, good folding resistance, strong toughness, sterilization and other effects, selling points are very good, but the market sales price is not low, generally more than 300 yuan, but there are still certain defects, It just minimizes the possibility of causing failure.
4, special electric blanket switch + double spiral hot wire
This design is dedicated to the special line, the data matching is relatively strong, the price is not low, belongs to the design range of high-grade electric blankets, the temperature of each gear, usually before leaving the factory has been designed, consumers only need to adjust the temperature they need according to the instructions of the manual, other temperature control systems will self-adjust, self-protection, do not worry about safety issues, because the technology used is advanced enough, security measures are strong enough, can be used with confidence!
