The electrode electric hot water bottle has potential safety hazards. Because the electrode is easy to rust, when the rust powder enters the liquid, it will lead to the decrease of liquid resistance, the increase of heating power and the increase of temperature. At this time, if the thermostat fails, the liquid will explode due to gasification when it exceeds a certain temperature. When an explosion occurs, hot water is everywhere, which is easy to cause injuries and burns.
In addition, because the liquid itself will be charged when heated, and there is no overvoltage protection device, when the electrode electric hot water bottle explodes or leaks, the user will not only be scalded, but also get an electric shock.
The heating wire (tube) hot water bottle has an insulated coil, which can separate the heating element from the liquid and is relatively safe.
Warm baby is a necessary artifact for many people to keep out the cold in winter. Fever lasts for a long time, small and light, and can be attached to the body to keep the baby warm. Warm baby produces a temperature of 50-60℃, which is attached to the outside of clothes and then transmitted to the human body. The skin can adapt and even feel comfortable, which makes us often ignore the protection of the skin and sometimes forget to take it off. Warm baby touching a certain skin for a long time, just like "boiling a frog in warm water", will unconsciously lead to cryogenic burns.
Especially for children, children's expression ability is poor, and it is easy to forget to take off the warm baby. Therefore, parents must take good care of the warm baby for their children, otherwise it will lead to cryogenic burns.
