The electric fan is also an indispensable summer appliance and the most used heat-cleaning appliance in the family at present. Compared with air conditioners, electric fans are less effective, but they are energy-efficient and do not consume electricity, and because they are easy to use and cheap, their market position is still indestructible. Electric fans have leaves, there are three leaves, four leaves, five leaves, so three leaves of electric fans or five leaves of electric fans good?
Three-blade electric fan or five-blade electric fan is good
Five-blade is certainly better than three-blade. After the fan becomes five-blade from three-blade, the blade becomes narrower and requires a thicker steel plate to achieve the same strength. In addition, the design of the blade shape, more complex than the original, with 50 tons of pressure stamping without molding, must be opened to 200 tons of pressure to do, the difficulty has increased quite a lot, the price is naturally high, more blades wind is relatively softer.
Fan blade is a very important point of purchase and inspection, fan blade material and the number of pieces directly affect the quality of the fan and the silent effect, generally speaking, the low-end electric fan fan blade is generally used AS material, and the mainstream is currently on the market is PP material, compared to the PP material fan blade on the soft side, in the case of wind is not bad more light and safe, of course, in fact, the two materials of the fan in the specific use of Of course, the difference between the two materials in the specific use of the fan is not very large; more noteworthy point is the number of blades, common electric fan fan blades for three, high-end fans will reach five, in the design of electric fans generally do not appear in an even number of blades, because the even number of blades of electric fans are prone to resonance in the rotation, causing damage, compared to the five-blade fan blowing out the wind is not only softer, and the silent effect will greatly exceed the three-blade fan.
The difference between three-blade electric fan and five-blade electric fan is not much, five-blade speed than the slow three-blade, noise will show slightly smaller, the balance is also better (jitter less) As for the wind smoothly, feel comfortable, I do not agree, many fans deliberately designed to change the wind speed in order to simulate the natural wind, safety factors are not talked about, as for heat dissipation, if you refer to heat dissipation to people, that is, wind power, and the number of leaves Irrelevant, if you refer to the fan itself, heat dissipation, blowing hot air to people.
Three electric fan leaves easy to loosen how to do
Glue gun inserted into the rubber strip heated by electricity, the fan blades are removed.
Fan blade removed, the rubber strip through the glue gun heated just softened.
Fan foot glue, pay attention not to the screws on the glue (screws are difficult to turn and turn bad).
Quickly install the fan blade on the screws.
The next two leaves fan blade as above, complete.
Three leaf electric fan price: 108 yuan, 24 yuan, 35 yuan, 38 yuan, 29 yuan, 25 yuan and other prices. (Price source network, for reference only)
Three leaf electric fan or five leaf electric fan is good? Here we can clearly tell you that the more leaves of the electric fan, the better the wind speed will be, which is the main willingness of people to choose a five-blade electric fan rather than a three-blade electric fan, of course, more leaves of the electric fan may also face the trouble of installation and removal, the leaves are easily damaged and need to be replaced frequently, etc.. When the electric fan is running, remember not to put your hands near the electric fan leaves, or your hands may be seriously injured.
