How many heating areas are more reasonable to design?
I am engaged in the production of heating sheet for more than 20 years, rich experience in the industry, extremely proficient in the circuit principle, know the truth, accounting for the professional point of view to analyze things, I do not recommend so many heating sheet, money is spent, the heating effect is not very ideal . The best state is 3-4 pieces of the working principle, 3 pieces of the principle is, back + left front + right front . The principle of 4 pieces of state is back + left front + right front + collar, of course, this is the problem of radish cabbage, to the customer's opinion shall prevail !
1, Cost of labor has increased a lot, 80% of the current clothing heating sheet are completely dependent on manual processing !
2, Although the heating sheet area is more, but the heating area is smaller, it will make people feel uncomfortable !
3, Number of heating sheet, the internal connection line will become more, the comfort will become worse !
4, More complex the line, the greater the probability of failure ! 5, Will cause the temperature of the heating sheet is too low !
The wearable products on the market, the working voltage is mostly 5V power supply, 7.4V is very rare, this is related to the cost, the same battery, 5V and 7.4V price will be very different . Output end of the battery is divided into two kinds, civil battery 1A, industrial battery 2A, to choose the latter, but once the working current exceeds the output current, the internal PCB board will take current limiting measures, forced power off, prohibit heating power supply . Is similar to cooking a pot of rice, one person can not finish, two people eat full, three people eat enough , four people eat just enough. Five people do not eat enough, six people eat bad principle !
In recent years, wearable products are more popular, especially electric clothing, electric socks, electric pants and other wearable products, the consultation is relatively large, There are also some customers who just entered the industry, professional cognition is not enough, always feel that the more the number of heating tablets to do the better, so that it will give people the heating sheet have strong function . In fact, this idea is absolutely wrong, first of all, the number of heating tablets, will face a lot of problems, and it is a very realistic problem.
