I have an old-fashioned electric fan at home. It was bought by my parents in the 1980s.
has been used for more than 20 years and has never been repaired.
In the 1980s and even the 1970s, electric fans were luxury goods at that time.
The electric fan purchased by my parents only cost less than 200 yuan back then, but it is much easier to use than the current electric fans.
0 The electric fan I purchased in the 1980s and 1970s has not broken for decades. Why does the electric fan I purchased now have to be replaced with a new one after two years? I believe many people don’t know this problem like me before. If you don’t know, you will understand after reading it. Why are the fans before
more durable?
. Fan blades are different
After comparing it, I found that the fan blades purchased in my parents' era were different from those of the current electric fans.
In the past, many old electric fan manufacturers produced metal fan blades.
Now most of the electric fans we see in the mall are plastic fan blades. Although
has become lighter in weight, it is not as durable as before and is more expensive.
. Don’t cut corners
In the past, technology was far from being as developed as it is now, and the products produced also had many shortcomings,
, but the quality of the products produced in that era was not as good as the products now.
In the past, there was basically no problem of cutting corners when production was performed,
But now many small manufacturers use inferior materials as good materials when producing electric fans.
In the past, the pass rate of the electric fans we purchased was very high in terms of material and internal parts,
But now many of the electric fans we purchased in shopping malls or supermarkets have no quality assurance.
. The motor is different
Motor is one of the important components of the fan. The previous electric fan motors used were all copper coils and sand steel sheets. The quality of the materials used in
is guaranteed, not only durable, but also has a small heat generation.
motors are mainly composed of coil and bearings . In the past, electric fans used bearings,
, but now many electric fans use steel sleeve when making them.
The steel sleeve has a running time too long, and there will be a problem of glue. After the steel sleeve is glued, the running speed will slow down and it will easily burn.
When the electric fan is running, the operation speed depends partly on the lubricant in the fan parts. When the
fan runs very fast, it will generate a continuous high temperature, causing the lubricant to gradually dry.
If the lubricating oil inside the fan loses the lubricating effect, it will reduce the service life of the part. When the parts are worn seriously, the fan will have problems with the use of it.
. Too much competition
Although the previous electric fans looked particularly bulky and were not as good as the current electric fans,
, most of the previous electric fans were metal materials, whether they were shells or internal materials.
However, because the competition is too fierce now and there are too many competitors,
Many fans ignore the quality when making it, and only improve the appearance of the fans. Fans like
are indeed more attractive, but they will be damaged soon when used.
If you want to buy a fan, it is recommended that you take a look at the following two old fans, which are cheap and durable.
