What is inside the charging hot water bag
After the water can be used to charge the hot water bag, after the water to clean the air, rapid expansion when charging, if the quality is not good, prone to short circuit or even explosion. In the purchase of hot water bags, should pay more attention to product packaging, pay attention to whether the above marked product identification, underwriting units, national standards, product description and use of attention, etc.. Due to the sale of a lot of heating supplies on the market, product quality is uneven, so pay attention to the choice of regular brands in the purchase, do not covet cheap buy. But when using, do not think that electric hot water to a certain temperature power will automatically jump, part of the product quality, the temperature keeps rising until the explosion. Therefore, the charging time should not be too long, people do not leave the electric hot water bottle, touch electric hot water temperature, found sufficient heat, early power, this can avoid the occurrence of excessive temperature and pressure ".
The bag is not generally liquid water, which contains a conductive material, hot water bag is electromagnetic heat generated by the solenoid that is closed to prevent leakage, if the electricity will cause magnetic field and magnetic iron is the interaction of the so-called water to produce eddy current and hysteresis and the heat generated, and transformer why fever is relevant because of hysteresis and eddy current heat, the transformer made of a piece of silicon steel sheet is to reduce the hysteresis and eddy current, so as to improve the efficiency, and the hot water bag is opposite, so the electricity heating. If replaced by water, because water is a bad conductor, it will not heat, so the bag of liquid can not be replaced with water.
Charging hot water bag inside the electrolyte, which is a mixture of water and chemical salts, a power due to water and electrolyte conductivity, heat quickly, very slow heat dissipation. Electric hot water in the electrolyte cannot easily change, if you accidentally fell out, can also add a small amount of salt - water.
