What is the liquid in the electric heating treasure?

It is a conductive liquid, that is, a mixed solution of water and a certain amount of electrolyte.

Electric heating treasure is divided into electrode type and electric heating wire type. Among them, there are positive and negative electrodes in the electrode type electric heating treasure, which are in direct contact with the liquid (electrolyte solution) in the bag. After the electrode is electrified, the solution is electrically heated for a short time (about 2 ~ 8 minutes), but the liquid expands quickly and is easy to explode. There is an insulator coil in the electric heating wire heater, which is obviously larger than the electrode heater.

Pay attention to four points when purchasing and using electric hot water bottles, and beware of electric hot water bottles becoming "pocket bombs":

First, to buy products produced by regular manufacturers in regular merchants, the products must have national "3C" certification and product certificate;

The second is to buy a hot water bottle with a heating wire and touch the heater of the hot water bottle. The heater of the electric heating wire is large, with a diameter of 7-8 cm, and the diameter of the electrode heater is 1-2 cm.

The third is to check whether the sealing of the electric hot water bottle is intact, whether the power cord is intact, and whether the power cord interface has cracks or other security risks;

Fourth, stop charging within 2 minutes after the indicator light goes out, thus prolonging the service life.
