What is the specific function of a Mini fan?

People will feel hot wherever they go in the hot summer. So often carry a cattail fan, in order to cool down anytime and anywhere. This is the simplest portable fan, with the continuous development of science and technology, people invented the electric fan, which is driven by an electric motor to drive the wind blade to force the air to flow. It is no longer dependent on manpower to rock the fan. In summer, people can easily and conveniently enjoy the coolness of artificial wind. Because ordinary electric fans rely entirely on electricity from the mains power grid to drive the fans, this has caused the limitation that they can only be used in cities with the mains power grid. Obviously, ordinary electric fans are not mini fans. Then, let’s introduce in detail what are the specific functions of a mini fan?

What is the operation principle of a mini fan?

In general, mini fans are used as an AC motor. But what are fans which used an AC motor? By AC power to drive, the voltage will be positive and negative, completely independent of the circuit control, the generation of the magnetic field. The frequency of the power supply is fixed, and the speed of change of the magnetic pole generated by the silicon steel sheet is determined by the frequency of the power supply. The higher the frequency, the faster the switching speed of the magnetic field will be, and theoretically the faster the rotational speed will be. However, the frequency should not be too fast, too fast will cause start-up difficulties. The internal structure of the AC motor fan is mainly based on the transformer. Most of the materials selected by the AC motor fans are made of domestic discharge needles, which are generally tungsten needles or stainless-steel materials. If the voltage is shaken too much, the service life of the transformer will be affected.

What are the advantages of a mini fan?

First of all, the most obvious benefit of mini fans must be reduced size and weight. There are a number of portable mini fans that can be easily carried out and used by people on the road or at work. Some mini fans, powered by USB ports, take this advantage to the extreme. Because you don't have to worry about running out of power, with the USB charging port, you can charge at any time, effectively extending the use of the mini fan, breaking the time limit.

What are the disadvantages of a mini fan?

While mini fans have many advantages, there are also some disadvantages, which, in general, outweigh the flaws. The biggest problem with mini fans is that they don't have enough wind. Because in the design, it is designed to be easy to carry, so its material is often plastic and not high hardness plastic, so its structure is not strong enough, easy to break.

Mini fans bring us a lot of conveniences, let us in the hot summer, have their own piece of cool. Although it has some small shortcomings, on the whole, people's enthusiasm for it is very high.  If you are in the mini fans business, you can consider our cost-effective products.
