1, water heater
Useful life: 8 years for electric water heaters and 6-8 years for gas water heaters
Due to the structure of hot and cold water pipes of water heaters, water is discharged from the upper part of the water tank during daily drainage, so dirt and water bases in the lower part cannot be seen.
So even though the flushed water looks clean during bathing, it is actually mixed with dirt in the tank. A lot of scale is not only dirty, but it will corrode the heating pipe when it is heated on the heating pipe. If it is left for a long time, it will cause hidden trouble such as leakage of electricity.
Teach you a trick, just go to the supermarket to buy the scale and use high-temperature water to melt, then pour it into the water tank in the water heater.

2, electric blanket
Useful life: 6 years
The life of the heat-insulating wire insulation layer in the electric blanket is only 6 years. If it is used for a long time, it is easy to age, crack, greatly reduce the insulation, and easily cause safety hazards such as burns, electric injuries, and fire.
When purchasing electric blankets, it is best to choose electric blankets with indicator lights and protection devices. If a short circuit occurs, the power supply can be cut off automatically.
When you use it for the first time and then use the electric blanket after not using it for a long period of time, it is best to flatten it and then apply the electricity for about 1 hour to observe if there is any abnormality.

3, microwave oven
Useful life: 10 years
If the microwave oven exceeds the service life, not only the heating effect will be greatly reduced, but also the oven door sagging will occur, increasing the microwave leakage coefficient and endangering the health.
When using a microwave oven to heat food, do not use metalware. Instead, choose heat-resistant ceramics, glass, and other utensils.
When food is wrapped in plastic, paper or other flammable materials, be sure to take care to prevent fire when heating.
Eggs, liquids or food in sealed containers should not be heated in a microwave oven to avoid explosion.

4, refrigerator
Useful life: 10~12 years
When the refrigerator is used for a long time, the compressor will be aging, which will not only affect the functions such as refrigeration and sterilization, but also lead to food odor and bacteria, and will also greatly increase power consumption and noise.
The refrigerator must be regularly cleaned of radiators, internal frost blocks and expired foods in order to avoid harm to health, in addition must avoid frequent switching machine impact compressor.

5, air conditioning
Useful life: 8~10 years
Air conditioning for a long time will not only cause water leakage, cooling effect worse, but also significantly increase the power consumption, in addition, if the evaporator fin oxidation, accumulation of dirt will also pollute the indoor environment, causing respiratory diseases.
Air conditioners must not be switched on and off frequently, not only for electricity but also for reducing the service life. It is also important to remember to regularly clean the filters and heat sinks to keep the air clean.

6, TV
Useful life: 5~7 years
If the television's electrical components are used for a long time, they are likely to cause failures, degraded insulation, fire, and burning. Coupled with the long-term accumulation of dust and dirt, the insulation and flame retardant properties of the body will be greatly reduced, and it will easily lead to burning and electric shock.
The gradual aging of electrical components will also result in unclear images and chattering.
When using the TV everyday, be sure not to switch the machine on and off frequently. It is better to reduce the screen brightness properly. Do not maintain high brightness for a long time, so as not to reduce the service life.
In addition, when not using a TV, it is best to cover the vents with a dust cover to prevent dust from collecting and damaging components.

7, washing machine
Useful life: 8~10 years
Long time washing machine not only leaks, short circuit, heat and other problems, along with the aging of the components will cause leakage, causing security risks.
Be sure to remove any hard objects such as coins from the pockets of the clothes before washing them, so as not to damage the washing machine by friction with the inner wall of the drum. In addition, be sure to remember to use common detergents to clean the washing machine to avoid deposition of dirt and bacteria.

8, pressure cooker
Useful life: 5-8 years
When the autoclave is used for a long time, the pressure resistance of the pot body and related components will be significantly reduced, and if it can not withstand excessive pressure it will cause an explosion. Therefore, the old-fashioned pressure cooker is best not to use for more than 5 years, while the electric pressure cooker is relatively safe.
Everyday, you must always open the pressure cooker outlet, and you need to replace the rubber ring in 2 years. If there is damage to the accessories, you must use the original accessories.
When cooking daily, remember that food should not exceed 4/5 of the capacity.
"Non-burning, nicotine for users, low tar content. As the heating temperature (below 500℃) is lower than the combustion temperature of traditional cigarettes (600-900℃), the harmful components produced by tobacco high-temperature combustion pyrolysis and thermal synthesis are reduced, and the release amount of side-flow smoke and environmental smoke (second-hand smoke) is also greatly reduced."
Heating non - combustion products are electronic devices containing tobacco. When you heat them, they produce a nicotine-containing vapor that you can inhale.
They are different from traditional cigarettes and work by heating tobacco to a very low temperature. Tobacco is heated to 350 ° C in a heat-incombustible device, while traditional cigarettes burn at up to 900 ° C.
Still, the temperature at which non-combustion products are heated is high enough to vaporize and inhale harmful chemicals.
Although both are electronic devices, heated non-combustible products are also different from e-cigarettes or steam devices. These usually use chemical liquids and do not necessarily contain nicotine. E-cigarettes tend to heat liquids to around 250 degrees Celsius to produce vapor.
