National standard hot water bag brand

Water and electricity separation of hot water bag brand is divided into two kinds of electric heating wire type heating handbag safer. At present, the electric heating handbag is usually divided into electrodes and electric heating wire type. The standard specifies the endurance, temperature rise, power failure and sealing degree of electric heating handbag. According to this regulation, the electrode type hand warmer has been banned from sale, allowing the continued sale of high safety electric heating wire type hand warmer. Electrode type hand warmer by making direct contact between the electrode and the liquid to generate heat, there is a great safety risk, the leakage of liquid electrocution hazard, China's hot water bag brand ranking of hot water bag companies without temperature control, easy to make the electric bag expansion explosion. Electric heating wire type electric heating bag insulation of the coil isolated heating body and liquid, safer. Explosive electrode type hand warmer is still very popular in the market. The main reason is the interest-driven, cost.

Mass production of electrode type hand warmer cost only about 67 yuan each, the new hot water bag electric heating wire type hand warmer due to the coil and insulation design increases, the cost is high, about 15 yuan each, is more than twice the electrode type. Driven by the interest, some small manufacturers and small businesses take the risk to sell more at low cost and thin profit in an attempt to gain more benefits.
