principle of operation
The warm water bag itself contains liquid. If a small piece of metal in the bag is slightly pressed, a chemical reaction will occur, and the liquid in the bag will immediately appear as a white object, which will solidify and heat up (can the heating time be guaranteed? Hold for about 20 minutes). When it's cold, you can boil it in boiling water for a few minutes, and then it becomes soft (water again). Repeat this cycle. Is the liquid in it coal liquid or water, which can quickly meet the pressure or heat energy? Heat up or expand.
Metal sheet has good heat transfer performance because it is metal. If you are good at physics, basically all the students in Grade 2 can tell you. This is a very typical example of endothermic heating. Because cold air is heavier than hot air, it always flows downward, which is more convenient for heating. If you are careful, you can observe the shape of a warm handbag.
What parts does the heating package include?
A heating bag comprises a sealed outer bag, an inner bag and a granular heater; The inner bag consists of a bottom surface and a top surface with micropores. The inner bag is placed in a sealed outer bag, and the heating element is placed in the inner bag. Granular hair? The heating element is a mixture, including iron powder, activated carbon and water. The heating bag of the utility model has a very simple structure and does not need external energy, electricity, gas, etc. And it is very convenient to use, especially suitable for special needs. Want people, such as arthritis, rheumatism, dysmenorrhea and other patients.

Some heating bags can be used on the feet, some on the abdomen, and some on the whole body. Most heating bags are designed by electric heating, because electric heating water heating bags are easier to heat and operate. Most heating bags are filled with water, because water is a relatively easy medium to heat. When we choose heating bags, we'd better choose some that can be electrically heated, because the group that can be electrically heated heats the bags faster. Pay attention to electricity safety when using heating package.
