Every winter, there will be some news reports about the improper use of small household appliances leading to family illness or injury. Jin Fengxi, a person in the household appliance maintenance industry, suggested that the correct use and daily maintenance of some small household appliances with high frequency at home in winter are very important.

Pay attention to the water quality of humidifier and clean it frequently
Winter is dry, most families will prepare one or more humidifiers, so how to use the humidifier correctly?

First of all, water is the most consumed in the humidifier. In order to save trouble, some families directly add tap water to the humidifier. In fact, it is unsafe to do so, which may cause damage to the humidifier, even pollute the environment, and affect the service life of the machine. If conditions permit, it is recommended to use purified water, or boil the tap water to cool before adding it to the humidifier. At the same time, do not add essential oils, disinfectants and other "ingredients" to the water. These things will not only adhere to the humidifier, affect the service life of the machine, but also stimulate the respiratory system of the human body. In serious cases, allergies and other symptoms will occur.

Secondly, the humidifier should be used appropriately. Generally, the indoor humidity should be controlled at 45% - 60%. If the humidity is too high, the indoor air quality will be affected. It is recommended to purchase intelligent humidifier, which can adjust the working state according to the indoor humidity. Finally, careful people may find that a layer of slippery substances will appear on the inner wall of the humidifier after being used for a period of time, which indicates that it needs to be cleaned. If it is not cleaned all the time, mold will appear in some corners, affecting human health.

Avoid prolonged heating of the thermos pot
In order to drink hot water at any time, many families choose to use thermos pots. The kettle is always plugged in, and the internal temperature control device will heat at any time according to the temperature of the water in the kettle. If there are few families and it takes a long time to drink a pot of water, it will be heated repeatedly for a long time, which will increase the scale in the pot. Because the scale contains some heavy metal elements, the accumulation will have a certain impact on human health. Therefore, it is necessary to avoid repeated heating of the water in the insulation pot for a long time, and pay attention to regularly cleaning the scale in the pot. For daily scale cleaning, only mix the white vinegar and water in the ratio of 1:2 and add them to the pot. After heating and standing for a few minutes, the scale inside will be decomposed, and then wash the inner wall of the pot.

Warm hand treasure should not be used while charging
Some people who are afraid of cold will have warm hand treasure. Because warm hand treasure needs to be recharged repeatedly, we must pay attention to its quality and buy the products of regular manufacturers. In the process of use, it is not recommended to directly contact the warm hand treasure with the skin for a long time. In particular, some people like to put the warm hand treasure into the quilt. Once they fall asleep, they are easy to be scalded. In addition, when it is used for the elderly and children, it can be wrapped with a towel.

It should be noted that when charging the warm hand treasure, it should be placed away from people as far as possible, because the internal temperature control components of the warm hand treasure may fail after repeated use. If its internal parts are damaged or aged, it is likely to explode, so do not use the hand warmer while charging.
