What is the liquid inside the electric hot water bag

Electric hot water bag inside is actually iron powder or ferrite, electric hot water bag is by electromagnetic heat generated by the electromagnetic things are closed up to prevent leakage of electricity, if the electricity is generated after the magnetic field, iron and magnetism are reacting to each other.

The so-called water inside the eddy current and hysteresis and then generated heat, and why the transformer will heat is related to the hysteresis and eddy current and heat, people make the transformer into a piece of silicon just piece is to reduce the hysteresis and eddy current, so as to improve efficiency.

The electric hot water bag is safe as long as you are careful not to burn yourself.

Extended information:

When using an electric hot water bag, you should pay attention to:

(1) Check the electric hot water bag before energizing it. Before energizing the electric hot water bag socket to check whether there are water droplets, in order to ensure that the socket should be dry for safety reasons. Then plug the electric hot water bag plug, and then plug the power plug for energization. At the end of the energization, you should first unplug the power plug, and then remove the electric hot water bag plug.

(2) In the process of energizing, the electric hot water bag can not be held in the arms, and is strictly prohibited to wrestle, sitting pressure, so as to avoid the liquid leakage. In the energized state is best not to leave the scene, pay attention to observe the indicator light, the indicator light off before indicating the end of the energized heat storage. General charging 5-10 minutes.

(3) It is strictly prohibited to use water boiling, fire baking and other ways of heating the electric hot water bag, if the liquid inside the electric hot water bag leakage should immediately stop using.

(4) It is strictly prohibited to use while charging, just charge the hot water bag, do not directly close to the skin, to prevent burns caused by the high temperature.

(5) to pay attention to the water temperature is not too hot, not too long, the hot water bag should be placed next to the feet of 10 centimeters, and not on the feet; it is best to put in the quilt before going to bed, and take it out when you go to bed.

(6) In the use of rechargeable hot water bag should be regularly open the bag on the plastic small hole cover, the air will be drained.

(7) the life of the electric hot water bag is generally about one or two years, even if the quality of the electric hot water bag, in the process of using the internal lines and construction is also aging, there are failures and short-circuit potential, if more than this time it is best to replace.
