National standard hot water bag ranking

Solid state electric heating cake, filled by insulation cotton (such as: asbestos, etc.), the working principle is: the use of dual temperature control electric heating energy storage structure, gradually release heat energy. With automatic overheating protection device and automatic insulation indicator, a small electric stove, controlled by PTC thermistor switch, PTC is a positive temperature coefficient thermistor. When the current passes through the stove, the stove itself will heat up (the heat of the stove will also be conducted to the stove), and the hot water bag wholesale manufacturer direct sales of the stove temperature reaches a certain value, its resistance will increase sharply. Therefore, at this time to stop consuming electricity, electric water heating bags wholesale after relying on insulation cotton on the electric stove insulation, what brand of water heating bags good slowly release heat.

Soft liquid rechargeable hot water bag

Soft liquid rechargeable hot water bag using a new type of energy storage heating agent, heating up fast. A water injection, can be used for a long time, a unique explosion-proof non-iron device, temperature control protection, long life, insulation lasting. Its working principle is based on the improved solid state electric heating cake, using electrode heating method, high-quality temperature control and thermal fuse temperature double insurance. When the temperature of the liquid in the bag reaches 65 degrees, the temperature control automatically disconnects the circuit and stops heating; when the temperature control control fails, the temperature control disconnects and stops heating and requires a new replacement, please do not try to repair.
