This utility model has following conspicuous advantage compared with prior art: one, adopt softish heating wire, outside to be with the resistant to elevated temperatures material of good insulation preformance, produce

It is stable that heat stability produces heat than insulating bag with the saline solution energising.Two, adopt the high sticking freeze and store hydrothermal solution store heat of heat accumulation efficient, and then throw thermal discharge, heat accumulation

Time long.Three, this utility model adopts whippy sticking freeze and store hydrothermal solution and soft insulated heating wire, has again

The overcoat insulated bag that flannelette or cotton are made can increase the time of throwing thermal discharge, so this

The soft high resilience of utility model electric heating bag is used more comfortable than electric warming bag.Four, this utility model electric heating bag has temperature, pressure, electric current three big protectors, the institute so that

With safe and reliable.It is easy to change heat accumulation liquor ratio maintenance electric warming bag when five, this utility model keeps in repair.Six, adopt the high-quality heating wire to make heater element,, use the longevity than making heater element with saline solution etc.

Life is long.Seven, this utility model is plugged attaching plug when heat accumulation, and heat accumulation liquid has stored up heat and has been about to power supply and inserts
