Why charging hot water bags when charging will drum up
The traditional hot water bag is only an empty bag made of rubber, usually square, with a hot water inlet, sealed with a plug, mostly a spiral plug. The use of the way to fill the hot water to play a role in heating. With the development of science and technology, the emergence of a new type of hot water bag on the market: electric heater and electric heating. Water storage type electric heating water bag, by filling liquid, which has a heater plug heating liquid in the bag, so as to achieve the purpose of heating. The utility model relates to an electric heating cake, which is filled with a heat insulation cotton, and the power supply can be used for heating the moisture cotton, so as to achieve the effect of heating.
Because the charging warm water bag filled with a certain amount of liquid, and adding a fever powder, electricity accelerated the flow of water, stimulate the black powder to produce chemical reaction, heat is released, this principle is charge of hot water bag. A person should have some knowledge of chemistry that chemical reactions will be generated, chemical reaction and stable precipitation and gas, so it is not difficult to explain with a period of time will drum up warm water bag charging.
Method for discharging charging hot water bag:1.. If the hot water bag is just overheated, need to wait until the temperature drops to normal temperature.2.. First set up the hot water bag, so that the water inlet upward, so as to prevent the plastic plug when the water flow out.3.. Pinch the end of the water inlet with one hand, and the other hand pulls the plug. When pulling out the rubber plug, be careful.4.. And then use the other hand to hold the bottom of the electric heating bag and gently press the air gradually discharged until a small amount of liquid outflow.5.. Finally tighten the rubber plug.
