Both ends of the electric heating wire are electrically connected with. Although there is a direct relationship between electricity and power, the greater the power, the shorter the time it takes to burn the same amount of water. Principle: Both ends of the heating wire are connected with the power cord respectively. After electrification, current flows through the heating wire, which generates heat. If the "quick heat" is immersed in the liquid, the heat will be released quickly through the liquid, so that the liquid can be heated quickly and the heating wire will not be burned out.
If left to air dry, the heat is not easy to dissipate, the metal outer tube will burn quickly, or even burn red, and the heating wire in the tube will also burn out. Therefore, when in use, the "quick heating" should be put into the liquid first, and the liquid should at least submerge the heating coil (the handle and wires should not be immersed in the liquid), and then the power supply should be turned on. Turn off the power supply after heating, and then take it out of the liquid to dry later.
Extended data:
Of course, you can drink water that boils quickly (the same principle as an electric kettle), but you should pay attention to:
1, to ensure that the water container and the heating container are cleaned quickly and do not rust. ;
2. The water in the container must not overheat too fast, nor dry burn too fast, otherwise it is easy to burn out;
Don't take the water out of the water immediately after it is boiled. Unplug the electric plug and take it out quickly when the water is cold, because it will heat up quickly and the temperature is still high, which is easy to burn out;
4. After the water boils, unplug the power plug. Because water is boiled for too long, it will lead to water aging and form harmful substances. Therefore, healthy water that meets human needs should be fresh. In addition, if the water is left for too long after boiling, it will also become aged water, and the toxic substances in aged water will increase with the increase of water storage time. Therefore, it is best to drink the water that was burned that day;
5. Because the electric heating wire in "fast heating" is made of nickel-iron alloy, it is generally brittle and easy to break. Therefore, "heating up quickly" cannot be shaken violently. If there is scale or attachment on the surface, you can gently brush it off with a small brush. Don't beat with hard objects, and don't scratch with a knife. Once the wire is broken, it can't be repaired, just need a new one;
6. When burning rapidly at high temperature, people should stay away, because some people put a little more water in the water bottle when boiling water, so some water may spill out during the burning process, and most of the spilled water is boiled water, so be careful not to let the water splash on your body;
7. It is best not to use it in the dormitory when the temperature rises quickly, because some of them have too much power and may cause unnecessary trouble. High-power electrical appliances are not allowed in university dormitories.
