However, although the car ashtray was cancelled, the cigarette lighter continued to exist in the car configuration table and became a standard. According to the survey data, the proportion of smokers among adults in China is about 28%, but it is lower than before.
The reason why cigarette lighters become standard is that cigarette lighters can meet the needs of some car owners. In addition to the low cost of cigarette lighters, there are also these stories behind the cigarette lighters becoming standard.
As early as 192 1, American Morris Company applied for the patent of the world's first "cordless" lighter, and around 1925, cigarette lighters became the standard of many cars with the trend at that time. Therefore, the origin of nearly a hundred years has also become the reason why lighters are difficult to give up.
Modern cigarette lighter was patented in 1960. At this time, the output power of cigarette lighters carried by many cars began to be 12V or 24V, and at the same time, many derivatives of cigarette lighters appeared-of course, there was no device to convert the USB charging port of cigarette lighters at that time, but taking power from the cigarette lighters could make the searchlights run.
There are still many wild animals in the suburbs of the United States at night, and in 1960, the number of bears and wolves is likely to be more or less. At this time, it is very important to see the environment clearly with searchlights before getting off the bus. Nowadays, many car electronic products are powered by cigarette lighters, such as driving recorders and car refrigerators, which is one reason why cigarette lighters are still standard today.
How to use the current lighter must not be taught. Just to remind you of a few points that you don't often pay attention to:
1. The cigarette lighter is overloaded
When using the cigarette lighter adapter to supply power, it is necessary to avoid the power load exceeding the output power of the cigarette lighter. Because the maximum current allowed by the cigarette lighter adapter is different, a mobile phone+an ipad may be overloaded. When there are many passengers on the bus, you need to pay special attention.
At the same time, the vehicle inverter powered by cigarette lighter can convert 12V DC into 220V AC, but the total power cannot be overloaded.
(Note that such a cigarette lighter adapter may be in danger of overload. )
2. The quality of cigarette lighter adapter is not up to standard.
Due to the wide variety of cigarette lighter adapters on the market, there are also many unqualified cigarette lighter adapters. Generally speaking, if there is an overload when taking electricity from the cigarette lighter, the internal safety of the cigarette lighter adapter will automatically fuse to prevent accidents. However, the unqualified cigarette lighter adapter has no overload protection function, and a short circuit may easily cause a fire.
Therefore, when purchasing a cigarette lighter adapter, we should not only buy products with reliable quality, but also pay attention to the need to replace the cigarette lighter adapter in time if it is loose or has poor contact. At the same time, if the metal contacts and their surroundings are black and the plug smells of burning, it means that the adapter of the cigarette lighter has failed and should be stopped immediately.
3. The cigarette lighter is directly exposed.
Most vehicles and lighters are equipped with covers, but some car owners accidentally lost the covers and failed to replace them in time. Once accidentally drenched in water or dropped into some coins and small metal objects, the lighter may be short-circuited or even spontaneously ignited, which is very dangerous!
Of course, if the cigarette lighter is used frequently, its snap spring has been deformed and needs to be repaired to avoid poor contact and short circuit.
