Although Rainbow's electric heating water bag is not its main product, with many years of experience in the production of electric blankets related to it, Rainbow electric heating water bag has high safety and has no quality problems in many national sampling inspections. Rainbow electric warm water bag is positioned in the mid-end market, the price is between 49~99 yuan, and the product is cost-effective. Its electric heating bags are mainly divided into two styles: electric heating pipe heating and electric heating wire heating, and they are also the two different types of mainstream electric heating bags on the market. Compared with the two, although the heating speed of the electric heating wire is not as good as that of the electric heating pipe, the heating is more uniform, and the price is generally more expensive than the electric heating pipe type warm water bag. In principle, the electric heating pipe is mainly heated by the power supply, and the power supply does not directly contact the liquid in the hot water bag, but adds the liquid through the electric heating pipe.
